have the potential to minimize environmental impact and improve resource efficiency by recycling the nutrient solution drained from a hydroponic (primary-donor) crop to irrigate another (secondary-receiver), less sensitive to salinity crop. However, it remains unclear if the drained solution from the primary crop can fully meet the nutritional requirements of a secondary crop and whether the productivity of the secondary crop is affected. To address this question, a prototype cascade hydroponic system was designed and tested using a cucumber crop as the donor crop and a melon as secondary crop. The performance of the system in terms of productivity and water and nutrient use efficiency was evaluated by measuring plant growth, fresh and dry matter production, nutrients content, and photosynthesis rate in the secondary crop. The amount of water and nutrients used for the primary and secondary crops was also recorded. This work was carried out under the ECONUTRI project that has received funding from the European Union’s Horizon 2020 research and innovation programme under the Horizon Europe Grant agreement: 101081858. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydroponics" title="hydroponics">hydroponics</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20use%20efficiencu" title=" water use efficiencu"> water use efficiencu</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrients%20use%20efficiency" title=" nutrients use efficiency"> nutrients use efficiency</a> </p> <a href="https://publications.waset.org/abstracts/175832/drainage-management-in-a-cascade-hydroponic-system-combination-of-cucumber-and-melon-crops" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175832.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Experience of Two Major Research Centers in the Diagnosis of Cardiac Amyloidosis from Transthyretin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Panagiotopoulos">Ioannis Panagiotopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Aristidis%20Anastasakis"> Aristidis Anastasakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstantinos%20Toutouzas"> Konstantinos Toutouzas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Iakovou"> Ioannis Iakovou</a>, <a href="https://publications.waset.org/abstracts/search?q=Charalampos%20Vlachopoulos"> Charalampos Vlachopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilis%20Voudris"> Vasilis Voudris</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgios%20Tziomalos"> Georgios Tziomalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstantinos%20Tsioufis"> Konstantinos Tsioufis</a>, <a href="https://publications.waset.org/abstracts/search?q=Efstathios%20Kastritis"> Efstathios Kastritis</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandros%20Briassoulis"> Alexandros Briassoulis</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimon%20Stamatelopoulos"> Kimon Stamatelopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexios%20Antonopoulos"> Alexios Antonopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Paraskevi%20Exadaktylou"> Paraskevi Exadaktylou</a>, <a href="https://publications.waset.org/abstracts/search?q=Evanthia%20Giannoula"> Evanthia Giannoula</a>, <a href="https://publications.waset.org/abstracts/search?q=Anastasia%20Katinioti"> Anastasia Katinioti</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Kalantzi"> Maria Kalantzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Evangelos%20Leontiadis"> Evangelos Leontiadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Eftychia%20Smparouni"> Eftychia Smparouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Malakos"> Ioannis Malakos</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Aravanis"> Nikolaos Aravanis</a>, <a href="https://publications.waset.org/abstracts/search?q=Argyrios%20Doumas"> Argyrios Doumas</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Koutelou"> Maria Koutelou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Cardiac amyloidosis from Transthyretin (ATTR-CA) is an infiltrative disease characterized by the deposition of pathological transthyretin complexes in the myocardium. This study describes the characteristics of patients diagnosed with ATTR-CA from 2019 until present at the Nuclear Medicine Department of Onassis Cardiac Surgery Center and AHEPA Hospital. These centers have extensive experience in amyloidosis and modern technological equipment for its diagnosis. Materials and Methods: Records of consecutive patients (N=73) diagnosed with any type of amyloidosis were collected, analyzed, and prospectively followed. The diagnosis of amyloidosis was made using specific myocardial scintigraphy with Tc-99m DPD. Demographic characteristics, including age, gender, marital status, height, and weight, were collected in a database. Clinical characteristics, such as amyloidosis type (ATTR and AL), serum biomarkers (BNP, troponin), electrocardiographic findings, ultrasound findings, NYHA class, aortic valve replacement, device implants, and medication history, were also collected. Some of the most significant results are presented. Results: A total of 73 cases (86% male) were diagnosed with amyloidosis over four years. The mean age at diagnosis was 82 years, and the main symptom was dyspnea. Most patients suffered from ATTR-CA (65 vs. 8 with AL). Out of all the ATTR-CA patients, 61 were diagnosed with wild-type and 2 with two rare mutations. Twenty-eight patients had systemic amyloidosis with extracardiac involvement, and 32 patients had a history of bilateral carpal tunnel syndrome. Four patients had already developed polyneuropathy, and the diagnosis was confirmed by DPD scintigraphy, which is known for its high sensitivity. Among patients with isolated cardiac involvement, only 6 had left ventricular ejection fraction below 40%. The majority of ATTR patients underwent tafamidis treatment immediately after diagnosis. Conclusion: In conclusion, the experiences shared by the two centers and the continuous exchange of information provide valuable insights into the diagnosis and management of cardiac amyloidosis. Clinical suspicion of amyloidosis and early diagnostic approach are crucial, given the availability of non-invasive techniques. Cardiac scintigraphy with DPD can confirm the presence of the disease without the need for a biopsy. The ultimate goal still remains continuous education and awareness of clinical cardiologists so that this systemic and treatable disease can be diagnosed and certified promptly and treatment can begin as soon as possible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amyloidosis" title="amyloidosis">amyloidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20scintigraphy" title=" myocardial scintigraphy"> myocardial scintigraphy</a>, <a href="https://publications.waset.org/abstracts/search?q=Tc-99m%20DPD" title=" Tc-99m DPD"> Tc-99m DPD</a>, <a href="https://publications.waset.org/abstracts/search?q=transthyretin" title=" transthyretin"> transthyretin</a> </p> <a href="https://publications.waset.org/abstracts/176716/experience-of-two-major-research-centers-in-the-diagnosis-of-cardiac-amyloidosis-from-transthyretin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176716.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Consumer Load Profile Determination with Entropy-Based K-Means Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20P.%20Panapakidis">Ioannis P.

Clustering-based load profiling is built upon the utilization of unsupervised machine learning tools for the purpose of formulating the typical load curves or load profiles. The most commonly used algorithm in the load profiling literature is the K-means. While the algorithm has been successfully tested in a variety of applications, its drawback is the strong dependence in the initialization phase. This paper proposes a novel modified form of the K-means that addresses the aforementioned problem. Simulation results indicate the superiority of the proposed algorithm compared to the K-means. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clustering" title="clustering">clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20profiling" title=" load profiling"> load profiling</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20modeling" title=" load modeling"> load modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency%20and%20quality" title=" energy efficiency and quality"> energy efficiency and quality</a> </p> <a href="https://publications.waset.org/abstracts/89525/consumer-load-profile-determination-with-entropy-based-k-means-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89525.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> pscmsForecasting: A Python Web Service for Time Series Forecasting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Andrianakis">Ioannis Andrianakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasileios%20Gkatas"> Vasileios Gkatas</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikos%20Eleftheriadis"> Nikos Eleftheriadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexios%20Ellinidis"> Alexios Ellinidis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermioni%20Avramidou"> Ermioni Avramidou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> pscmsForecasting is an open-source web service that implements a variety of time series forecasting algorithms and exposes them to the user via the ubiquitous HTTP protocol.

The System Operator solves an optimization routine aiming at the minimization of the cost of produced electricity. The solution of the optimization problem leads to the calculation of the System Marginal Price (SMP). Accurate forecasts of the SMP can lead to increased profits and more efficient portfolio management from the producer`s perspective. Aim of this study is to provide a comparative analysis of various machine learning models such as artificial neural networks and neuro-fuzzy models for the prediction of the SMP of the Greek market. Machine learning algorithms are favored in predictions problems since they can capture and simulate the volatilities of complex time series. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deregulated%20energy%20market" title="deregulated energy market">deregulated energy market</a>, <a href="https://publications.waset.org/abstracts/search?q=forecasting" title=" forecasting"> forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20marginal%20price" title=" system marginal price"> system marginal price</a> </p> <a href="https://publications.waset.org/abstracts/85227/comparison-of-machine-learning-models-for-the-prediction-of-system-marginal-price-of-greek-energy-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85227.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> PredictionSCMS: The Implementation of an AI-Powered Supply Chain Management System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Andrianakis">Ioannis Andrianakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasileios%20Gkatas"> Vasileios Gkatas</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikos%20Eleftheriadis"> Nikos Eleftheriadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexios%20Ellinidis"> Alexios Ellinidis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermioni%20Avramidou"> Ermioni Avramidou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper discusses the main aspects involved in the development of a supply chain management system using the newly developed PredictionSCMS software as a basis for the discussion.

On the other hand, Food and Nutrition Security (FNS) has evolved dramatically during the last decades in theory and practice serving as a reference point for exchanging experiences among all agents involved in programs and projects to fostering policy and strategy development. Global pressures make it more important than ever to gain a better understanding of the contribution that agrifood businesses make to FNS and to examine ways to make them more resilient in an increasingly globalized and uncertain world. This study extends the standard three-dimensional model of sustainability to include two more dimensions: A technological dimension and a policy/political dimension. Apart from the economic, environmental and social dimensions regularly used in sustainability literature, the extended model will accurately represent the measures and policies addressing food and nutrition security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20and%20nutrition%20security" title="food and nutrition security">food and nutrition security</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title=" food safety"> food safety</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/41913/an-extended-model-for-sustainable-food-and-nutrition-security-in-the-agrifood-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41913.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Voltage Sag Characteristics during Symmetrical and Asymmetrical Faults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Binas">Ioannis Binas</a>, <a href="https://publications.waset.org/abstracts/search?q=Marios%20Moschakis"> Marios Moschakis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrical faults in transmission and distribution networks can have great impact on the electrical equipment used. Fault effects depend on the characteristics of the fault as well as the network itself. It is important to anticipate the network’s behavior during faults when planning a new equipment installation, as well as troubleshooting. Moreover, working backwards, we could be able to estimate the characteristics of the fault when checking the perceived effects. Different transformer winding connections dominantly used in the Greek power transfer and distribution networks and the effects of 1-phase to neutral, phase-to-phase, 2-phases to neutral and 3-phase faults on different locations of the network were simulated in order to present voltage sag characteristics. The study was performed on a generic network with three steps down transformers on two voltage level buses (one 150 kV/20 kV transformer and two 20 kV/0.4 kV). We found that during faults, there are significant changes both on voltage magnitudes and on phase angles. The simulations and short-circuit analysis were performed using the PSCAD simulation package. This paper presents voltage characteristics calculated for the simulated network, with different approaches on the transformer winding connections during symmetrical and asymmetrical faults on various locations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phase%20angle%20shift" title="Phase angle shift">Phase angle shift</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20quality" title=" power quality"> power quality</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer%20winding%20connections" title=" transformer winding connections"> transformer winding connections</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20sag%20propagation" title=" voltage sag propagation"> voltage sag propagation</a> </p> <a href="https://publications.waset.org/abstracts/123004/voltage-sag-characteristics-during-symmetrical-and-asymmetrical-faults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123004.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Performants: A Digital Event Manager-Organizer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Andrianakis">Ioannis Andrianakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Manolis%20Falelakis"> Manolis Falelakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Pavlidou"> Maria Pavlidou</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstantinos%20Papakonstantinou"> Konstantinos Papakonstantinou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermioni%20Avramidou"> Ermioni Avramidou</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Kalogiannis"> Dimitrios Kalogiannis</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Milios"> Nikolaos Milios</a>, <a href="https://publications.waset.org/abstracts/search?q=Katerina%20Bountakidou"> Katerina Bountakidou</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiriakos%20Chatzidimitriou"> Kiriakos Chatzidimitriou</a>, <a href="https://publications.waset.org/abstracts/search?q=Panagiotis%20Panagiotopoulos"> Panagiotis Panagiotopoulos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artistic events, such as concerts and performances, are challenging to organize because they involve many people with different skill sets. Small and medium venues often struggle to afford the costs and overheads of booking and hosting remote artists, especially if they lack sponsors or subsidies. This limits the opportunities for both venues and artists, especially those outside of big cities. However, more and more research shows that audiences prefer smaller-scale events and concerts, which benefit local economies and communities. To address this challenge, our project “PerformAnts: Digital Event Manager-Organizer” aims to develop a smart digital tool that automates and optimizes the processes and costs of live shows and tours. By using machine learning, applying best practices and training users through workshops, our platform offers a comprehensive solution for a growing market, enhances the mobility of artists and the accessibility of venues and allows professionals to focus on the creative aspects of concert production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=event%20organization" title="event organization">event organization</a>, <a href="https://publications.waset.org/abstracts/search?q=creative%20industries" title=" creative industries"> creative industries</a>, <a href="https://publications.waset.org/abstracts/search?q=event%20promotion" title=" event promotion"> event promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/170627/performants-a-digital-event-manager-organizer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Recovery and Εncapsulation of Μarine Derived Antifouling Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20Stramarkou">Marina Stramarkou</a>, <a href="https://publications.waset.org/abstracts/search?q=Sofia%20Papadaki"> Sofia Papadaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Kaloupi"> Maria Kaloupi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Batzakas"> Ioannis Batzakas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biofouling is a complex problem of the aquaculture industry, as it reduces the efficiency of the equipment and causes significant losses of cultured organisms. Nowadays, the current antifouling methods are proved to be labor intensive, have limited lifetime and use toxic substances that result in fish mortality. Several species of marine algae produce a wide variety of biogenic compounds with antibacterial and antifouling properties, which are effective in the prevention and control of biofouling and can be incorporated in antifouling coatings. In the present work, Fucus spiralis, a species of macro algae, and Chlorella vulgaris, a well-known species of microalgae, were used for the isolation and recovery of bioactive compounds, belonging to groups of fatty acids, lipopeptides and amides. The recovery of the compounds was achieved through the application of the ultrasound- assisted extraction, an environmentally friendly method, using green, non-toxic solvents. Moreover, the coating of the antifouling agents was done by innovative encapsulation and coating methods, such as electro-hydrodynamic process. For the encapsulation of the bioactive compounds natural matrices were used, such as polysaccharides and proteins. Water extracts that were incorporated in protein matrices were considered the most efficient antifouling coating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algae" title="algae">algae</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound-assisted%20extraction" title=" ultrasound-assisted extraction"> ultrasound-assisted extraction</a> </p> <a href="https://publications.waset.org/abstracts/69052/recovery-and-encapsulation-of-marine-derived-antifouling-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69052.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Haptic Cycle: Designing Enhanced Museum Learning Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Menelaos%20N.%20Katsantonis">Menelaos N.

In this study, the Haptic Cycle is presented, a cycle of museum activities proposed for the development of museum learning approaches with optimized effectiveness and engagement. Haptic Cycle envisages the improvement of the museum’s services by offering a wide range of activities. Haptic Cycle activities make the museum’s exhibitions more approachable by bringing them closer to the visitors. Visitors can interact with the museum’s artifacts and explore them haptically and sonically. Haptic Cycle proposes constructivist learning activities in which visitors actively construct their knowledge by exploring the artifacts, experimenting with them and realizing their importance. Based on the Haptic Cycle, we developed the HapticSOUND system, an innovative virtual reality system that includes an advanced user interface that employs gesture-based technology. HapticSOUND’s interface utilizes the leap motion gesture recognition controller and a 3D-printed traditional Cretan lute, utilized by visitors to perform various activities such as exploring the lute and playing notes and songs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=haptic%20cycle" title="haptic cycle">haptic cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=HapticSOUND" title=" HapticSOUND"> HapticSOUND</a>, <a href="https://publications.waset.org/abstracts/search?q=museum%20learning" title=" museum learning"> museum learning</a>, <a href="https://publications.waset.org/abstracts/search?q=gesture-based" title=" gesture-based"> gesture-based</a>, <a href="https://publications.waset.org/abstracts/search?q=leap%20motion" title=" leap motion"> leap motion</a> </p> <a href="https://publications.waset.org/abstracts/165300/haptic-cycle-designing-enhanced-museum-learning-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165300.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Government (Big) Data Ecosystem: Definition, Classification of Actors, and Their Roles </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Iftikhar%20Hussain%20Shah">Syed Iftikhar Hussain Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilis%20Peristeras"> Vasilis Peristeras</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Magnisalis"> Ioannis Magnisalis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organizations, including governments, generate (big) data that are high in volume, velocity, veracity, and come from a variety of sources.

The key objectives of this paper are to propose a robust definition of government (big) data ecosystem and a classification of government (big) data ecosystem actors and their roles. We showcase a graphical view of actors, roles, and their relationship in the government (big) data ecosystem. We also discuss our research findings. We did not find too much published research articles about the government (big) data ecosystem, including its definition and classification of actors and their roles.

In this paper, we describe PerformAnts, a platform that increases the mobility of musicians and their accessibility to remotely located venues by rationalizing the cost of live acts. By analyzing the event history and taking into account their potential availability, the platform provides bespoke recommendations to both bands and venues while also facilitating the organization of tours and helping rationalize transportation expenses by realizing an innovative mechanism called “chain booking”. Moreover, the platform provides an environment where complicated tasks such as technical and financial negotiations, concert promotion or copyrights are easily manipulated by users using best practices. The proposed solution provides important benefits to the whole spectrum of small/medium size concert organizers, as the complexity and the cost of the production are rationalized. The environment is also very beneficial for local talent, musicians that are very mobile, venues located away from large urban areas or in touristic destinations, and managers who will be in a position to coordinate a larger number of musicians without extra effort. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20industry" title=" music industry"> music industry</a>, <a href="https://publications.waset.org/abstracts/search?q=creative%20industries" title=" creative industries"> creative industries</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20applications" title=" web applications"> web applications</a> </p> <a href="https://publications.waset.org/abstracts/162544/performants-making-the-organization-of-concerts-easier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162544.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">96</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Blockchain for Transport: Performance Simulations of Blockchain Network for Emission Monitoring Scenario</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dermot%20O%27Brien">Dermot O'Brien</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasileios%20Christaras"> Vasileios Christaras</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgios%20Fontaras"> Georgios Fontaras</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Nai%20Fovino"> Igor Nai Fovino</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Kounelis"> Ioannis Kounelis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rise of the Internet of Things (IoT), 5G, and blockchain (BC) technologies, vehicles are becoming ever increasingly connected and are already transmitting substantial amounts of data to the original equipment manufacturers (OEMs) servers. This data could be used to help detect mileage fraud and enable more accurate vehicle emissions monitoring. This would not only help regulators but could enable applications such as permitting efficient drivers to pay less tax, geofencing for air quality improvement, as well as pollution tolling and trading platforms for transport-related businesses and EU citizens. Other applications could include traffic management and shared mobility systems. BC enables the transmission of data with additional security and removes single points of failure while maintaining data provenance, identity ownership, and the possibility to retain varying levels of privacy depending on the requirements of the applied use case. This research performs simulations of vehicles interacting with European member state authorities and European Commission BC nodes that are running hyperleger fabric and explores whether the technology is currently feasible for transport applications such as the emission monitoring use-case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=future%20transportation%20systems" title="future transportation systems">future transportation systems</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20innovations" title=" technological innovations"> technological innovations</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20approaches%20for%20transportation%20future" title=" policy approaches for transportation future"> policy approaches for transportation future</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20and%20regulatory%20trends" title=" economic and regulatory trends"> economic and regulatory trends</a>, <a href="https://publications.waset.org/abstracts/search?q=blockchain" title=" blockchain"> blockchain</a> </p> <a href="https://publications.waset.org/abstracts/141507/blockchain-for-transport-performance-simulations-of-blockchain-network-for-emission-monitoring-scenario" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Government Big Data Ecosystem: A Systematic Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Iftikhar%20Hussain%20Shah">Syed Iftikhar Hussain Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilis%20Peristeras"> Vasilis Peristeras</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Magnisalis"> Ioannis Magnisalis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data that is high in volume, velocity, veracity and comes from a variety of sources is usually generated in all sectors including the government sector.

Continuous soil erosion measurements are required in order to comprehend the erosional processes and propose effective and efficient conservation measures to mitigate surface erosion. Mitigating soil erosion, especially in Mediterranean countries such as Greece, is essential in order to maintain environmental and agricultural sustainability. In this paper, we present the Automated Soil Erosion Monitoring System (ASEMS) that measures surface soil erosion along with other factors that impact erosional process. Specifically, this system measures ground level changes (surface soil erosion), rainfall, air temperature, soil temperature and soil moisture. Another important innovation is that the data will be collected by remote communication. In addition, stakeholder’s awareness is a key factor to help reduce any environmental problem. The different dissemination activities that were utilized are described. The overall outcomes were the development of an innovative system that can measure erosion very accurately. These data from the system help study the process of erosion and find the best possible methods to reduce erosion. The dissemination activities enhance the stakeholder's and public's awareness on surface soil erosion problems and will lead to the adoption of more effective soil erosion conservation practices in Greece. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20management" title="soil management">soil management</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20technologies" title=" new technologies"> new technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation%20practices" title=" conservation practices"> conservation practices</a> </p> <a href="https://publications.waset.org/abstracts/38394/the-automated-soil-erosion-monitoring-system-asems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38394.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Natural Regeneration Assessment of a Double Bunrt Mediterranean Coniferous Forest: A Pilot Study from West Peloponnisos, Greece</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dionisios%20Panagiotaras">Dionisios Panagiotaras</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20P.%20Kokkoris"> Ioannis P.

The present study concerns a pilot assessment of natural vegetation regeneration in the second, in terms of area, fire-affected region for 2021, at Ancient Olympia area, located in West Peloponnisos (Ilia Prefecture), Greece. A standardised field sampling protocol for assessing natural regeneration was implemented at selected sites where the forest fire had occurred previously (in 2007), and the vegetation (Pinus halepensis forest) had regenerated naturally. The results of the study indicate the loss of the established natural regeneration of Pinus halepensis forest, as well as of the tree-layer in total. Post-fire succession species are recorded to the shrub and the herb layer, with a varying cover. Present findings correspond to the results of field work and analysis one year after the fire, which will form the basis for further research and conclusions on taking action for restoration schemes in areas that have been affected by fire more than once within a 20-year period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forest" title="forest">forest</a>, <a href="https://publications.waset.org/abstracts/search?q=pinus%20halepensis" title=" pinus halepensis"> pinus halepensis</a>, <a href="https://publications.waset.org/abstracts/search?q=ancient%20olympia" title=" ancient olympia"> ancient olympia</a>, <a href="https://publications.waset.org/abstracts/search?q=post%20fire%20vegetation" title=" post fire vegetation"> post fire vegetation</a> </p> <a href="https://publications.waset.org/abstracts/173710/natural-regeneration-assessment-of-a-double-bunrt-mediterranean-coniferous-forest-a-pilot-study-from-west-peloponnisos-greece" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173710.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Contrast-to-Noise Ratio Comparison of Different Calcification Types in Dual Energy Breast Imaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vaia%20N.%20Koukou">Vaia N.

These include calcium carbonate, calcium oxalate, hydroxyapatite and aluminum. The aim of this study is to compare the contrast-to-noise ratio (CNR) values of the different calcification types using the dual energy method. The constructed calcification phantom consisted of three different calcification types and thicknesses: hydroxyapatite, calcite and calcium oxalate of 100, 200, 300 thicknesses. The breast tissue equivalent materials were polyethylene and polymethyl methacrylate slabs simulating adipose tissue and glandular tissue, respectively. The total thickness was 4.2 cm with 50% fixed glandularity. The low- (LE) and high-energy (HE) images were obtained from a tungsten anode using 40 kV filtered with 0.1 mm cadmium and 70 kV filtered with 1 mm copper, respectively. A high resolution complementary metal-oxide-semiconductor (CMOS) active pixel sensor (APS) X-ray detector was used. The total mean glandular dose (MGD) and entrance surface dose (ESD) from the LE and HE images were constrained to typical levels (MGD=1.62 mGy and ESD=1.92 mGy). On average, the CNR of hydroxyapatite calcifications was 1.4 times that of calcite calcifications and 2.5 times that of calcium oxalate calcifications. The higher CNR values of hydroxyapatite are attributed to its attenuation properties compared to the other calcification materials, leading to higher contrast in the dual energy image. This work was supported by Grant Ε.040 from the Research Committee of the University of Patras (Programme K. Karatheodori). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcification%20materials" title="calcification materials">calcification materials</a>, <a href="https://publications.waset.org/abstracts/search?q=CNR" title=" CNR"> CNR</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20energy" title=" dual energy"> dual energy</a>, <a href="https://publications.waset.org/abstracts/search?q=X-rays" title=" X-rays"> X-rays</a> </p> <a href="https://publications.waset.org/abstracts/63600/contrast-to-noise-ratio-comparison-of-different-calcification-types-in-dual-energy-breast-imaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63600.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Liver Histopathological Findings after Treatment with Anastrazole and Letrozole in Ovariectomized Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Boutas">Ioannis Boutas</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilios%20Pergialiotis"> Vasilios Pergialiotis</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolaos%20Salakos"> Nicolaos Salakos</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Agrogiannis"> George Agrogiannis</a>, <a href="https://publications.waset.org/abstracts/search?q=Panagiotis%20Konstantopoulos"> Panagiotis Konstantopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Laskarina-Maria%20Korou"> Laskarina-Maria Korou</a>, <a href="https://publications.waset.org/abstracts/search?q=Theodoros%20Kalampokas"> Theodoros Kalampokas</a>, <a href="https://publications.waset.org/abstracts/search?q=Odysseas%20Gregoriou"> Odysseas Gregoriou</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Creatsas"> George Creatsas</a>, <a href="https://publications.waset.org/abstracts/search?q=Despina%20Perrea"> Despina Perrea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The effect of third generation aromatase inhibitors in the lipid profile among women with breast cancer, present diversities. It has been also shown that low levels of estrogens affect liver metabolism in mice in numerous ways, such as lipid accumulation and hepatic steatosis. Materials and Methods: Forty-five female Wistar rats underwent surgical ovariectomy. The animals were anesthetized with a combination of ketamine (75 mg/kg) and xylazine (10 mg/kg) which were administered intraperitoneally. After the ovariectomy, the operated animals were randomized in three groups. The first group did not receive any drug regimen (ovariectomized control group). The second group received Anastrazole and the third group received Letrozole. Four months after the initiation of the study, the animals were euthanized and livers were dissected immediately for further histopathological analysis. The histological features were grouped into 4 broad categories: steatosis, ballooning, portal inflammation and lobular activity. A score from 0 (absence) to 3 (severe) was assigned to each parameter. Results: The liver pathology analysis revealed significant differences among groups with favored mild steatosis and ballooning among animals that received Anastrazole or Letrozole. Conclusion: The effect of Anastrazole and Letrozole on liver function have not yet been clarified. In our study mild histological liver alterations seem also to occur and these alterations should be taken in mind in future clinical studies <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anastrazole" title="anastrazole">anastrazole</a>, <a href="https://publications.waset.org/abstracts/search?q=letrozole" title=" letrozole"> letrozole</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=rats" title=" rats"> rats</a> </p> <a href="https://publications.waset.org/abstracts/38653/liver-histopathological-findings-after-treatment-with-anastrazole-and-letrozole-in-ovariectomized-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38653.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Combined Effects of Thymol, Carvacrol and Packaging on the Shelf-Life of Marinated Chicken</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Layal%20Karam">Layal Karam</a>, <a href="https://publications.waset.org/abstracts/search?q=Rayan%20Roustom"> Rayan Roustom</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20G.%20%20Abiad"> Mohamad G.

To date, limited data on addition of active components of Essential Oils (EOs) to marinades for chicken preservation are available. The antimicrobial effect of carvacrol and thymol, added at 0.4 and 0.8% v/w to marinated fresh chicken, stored in air and under vacuum packaging (VP), for 21 days at 4°C, was examined. The samples were monitored for microbiological (total viable count (TVC), lactic acid bacteria (LAB), Brochothrix thermosphacta, Pseudomonas spp., total coliforms, Escherichia coli, yeasts and molds) and sensory attributes (odor characteristics). Our data supports that among the tested microorganisms, Pseudomonas spp., LAB and B. thermosphacta were the most dominant microbiota in the marinated chicken samples. Additionally, the use of active EOs components, especially the higher concentration (0.8% v/w) in combination with VP, retarded the growth of spoilage microbiota and resulted in a significant reduction of about 2.9-3.1 log cfu/g and a microbiological shelf-life extension of marinated chicken by > 6 days, as judged by TVC data. Interestingly, the combination of active components of EOs at the lower concentration (0.4% v/w) and packaging (air or vacuum) resulted in a significant sensorial shelf-life extension of 15 and >21 days, as compared to the controls’ shelf-life of 9 days. The results of our study demonstrated the potential of the active components, carvacrol and thymol, as natural effective antimicrobial hurdles to control the growth of spoilage microorganisms in marinated chicken meat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chicken" title="chicken">chicken</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils%20compounds" title=" essential oils compounds"> essential oils compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=marination" title=" marination"> marination</a>, <a href="https://publications.waset.org/abstracts/search?q=meat%20spoilage" title=" meat spoilage"> meat spoilage</a>, <a href="https://publications.waset.org/abstracts/search?q=preservation" title=" preservation"> preservation</a> </p> <a href="https://publications.waset.org/abstracts/97038/combined-effects-of-thymol-carvacrol-and-packaging-on-the-shelf-life-of-marinated-chicken" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97038.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Mitigation of Wind Loads on a Building Using Small Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arindam%20Chowdhury">Arindam Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Tremante"> Andres Tremante</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadtaghi%20Moravej"> Mohammadtaghi Moravej</a>, <a href="https://publications.waset.org/abstracts/search?q=Bodhisatta%20Hajra"> Bodhisatta Hajra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Zisis"> Ioannis Zisis</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Irwin"> Peter Irwin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extreme wind events, such as hurricanes, have caused significant damage to buildings, resulting in losses worth millions of dollars. The roof of a building is most vulnerable to wind-induced damage due to the high suctions experienced by the roof in extreme wind conditions. Wind turbines fitted to buildings can help generate energy, but to our knowledge, their application to wind load mitigation is not well known. This paper presents results from an experimental study to assess the effect of small wind turbines (developed and patented by the first and second authors) on the wind loads on a low rise building roof. The tests were carried out for an open terrain at the Wall of Wind (WOW) experimental facility at Florida International University (FIU), Miami, Florida, USA, for three cases – bare roof, roof fitted with wind turbines placed closer to the roof edges, and roof with wind turbines placed away from the roof edges. Results clearly indicate that the presence of the wind turbines reduced the mean and peak pressure coefficients (less suction) on the roof when compared to the bare deck case. Furthermore, the peak pressure coefficients were found to be lower (less suction) when the wind turbines were placed closer to the roof, than away from the roof. Flow visualization studies using smoke and gravel clearly showed that the presence of the turbines disrupted the formation of vortices formed by cornering winds, thereby reducing roof suctions and preventing lift off of roof coverings. This study shows that the wind turbines besides generating wind energy, can be used for mitigating wind induced damage to the building roof. Future research must be directed towards understanding the effect of these wind turbines on other roof geometries (e.g. hip/gable) in different terrain conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wall%20of%20wind" title="wall of wind">wall of wind</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20loads" title=" wind loads"> wind loads</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title=" wind turbine"> wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=building" title=" building"> building</a> </p> <a href="https://publications.waset.org/abstracts/76245/mitigation-of-wind-loads-on-a-building-using-small-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76245.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">249</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Microstructural Evolution of an Interface Region in a Nickel-Based Superalloy Joint Produced by Direct Energy Deposition </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Ferguson">Matthew Ferguson</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatyana%20Konkova"> Tatyana Konkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Violatos"> Ioannis Violatos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microstructure analysis of additively manufactured (AM) materials is an important step in understanding the interrelationship between mechanical properties and materials performance. Literature on the effect of laser-based AM process parameters on the microstructure in the substrate-deposit interface is limited. The interface region, the adjoining area of substrate and deposit, is characterized by the presence of the fusion zone (FZ) and heat-affected zone (HAZ), experiencing rapid thermal gyrations resulting in thermal-induced transformations. Inconel 718 was utilized as work material for both the substrate and deposit. Three blocks of Inconel 718 material were deposited by Direct Energy Deposition (DED) using three different laser powers, 550W, 750W and 950W, respectively. A coupled thermo-mechanical transient approach was utilized to correlate temperature history to the evolution of microstructure. The thermal history of the deposition process was monitored with the thermocouples installed inside the substrate material. The interface region of the blocks was analyzed with Optical Microscopy (OM) and Scanning Electron Microscopy (SEM), including the electron back-scattered diffraction (EBSD) technique. Laser power was found to influence the dissolution of intermetallic precipitated phases in the substrate and grain growth in the interface region. Microstructure and thermal history data were utilized to draw conclusive comparisons between the investigated process parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20energy%20deposition" title=" direct energy deposition"> direct energy deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20back-scattered%20diffraction" title=" electron back-scattered diffraction"> electron back-scattered diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=inconel%20718" title=" inconel 718"> inconel 718</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20microscopy" title=" optical microscopy"> optical microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscopy" title=" scanning electron microscopy"> scanning electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=substrate-deposit%20interface%20region" title=" substrate-deposit interface region"> substrate-deposit interface region</a> </p> <a href="https://publications.waset.org/abstracts/137537/microstructural-evolution-of-an-interface-region-in-a-nickel-based-superalloy-joint-produced-by-direct-energy-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137537.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Application of Customized Bioaugmentation Inocula to Alleviate Ammonia Toxicity in CSTR Anaerobic Digesters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yixin%20Yan">Yixin Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Miao%20Yan"> Miao Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Irini%20Angelidaki"> Irini Angelidaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Fotidis"> Ioannis Fotidis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ammonia, which derives from the degradation of urea and protein-substrates, is the major toxicant of the commercial anaerobic digestion reactors causing loses of up to 1/3 of their practical biogas production, which reflects directly on the overall revenue of the plants.

Three continuous stirred-tank reactors (CSTR), fed with the organic fraction of municipal solid waste at a hydraulic retention time of 15 days and operated at thermophilic (55°C) conditions were assessed. After an ammonia shock of 4 g NH4+-N L-1, the customized inocula were bioaugmented into the CSTR reactors to alleviate ammonia toxicity effect on AD process. Recovery rate of methane production and methanogenic activity will be assessed to evaluate the bioaugmentation performance, while 16s rRNA gene sequence will be used to reveal the difference of microbial community changes through bioaugmentation. At the microbial level, the microbial community structures of the four reactors will be analysed to find the mechanism of bioaugmentation. Changes in hydrogen formation potential will be used to predict direct interspecies electron transfer (DIET) between ammonia tolerant methanogens and syntrophic bacteria. This experimental work is expected to create bioaugmentation inocula that will be easy to obtain, transport, handled and bioaugment in AD reactors to efficiently alleviate the ammonia toxicity, without alternating any of the other operational parameters including the ammonia-rich feedstocks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artisanal%20fishing%20waste" title="artisanal fishing waste">artisanal fishing waste</a>, <a href="https://publications.waset.org/abstracts/search?q=acidogenesis" title=" acidogenesis"> acidogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20fatty%20acids" title=" volatile fatty acids"> volatile fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</a>, <a href="https://publications.waset.org/abstracts/search?q=inoculum%2Fsubstrate%20ratio" title=" inoculum/substrate ratio"> inoculum/substrate ratio</a> </p> <a href="https://publications.waset.org/abstracts/125008/application-of-customized-bioaugmentation-inocula-to-alleviate-ammonia-toxicity-in-cstr-anaerobic-digesters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Conversion of Sweet Sorghum Bagasse to Sugars for Succinic Acid Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enlin%20Lo">Enlin Lo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Dogaris"> Ioannis Dogaris</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Philippidis"> George Philippidis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Succinic acid is a compound used for manufacturing lacquers, resins, and other coating chemicals. It is also used in the food and beverage industry as a flavor additive. It is predominantly manufactured from petrochemicals, but it can also be produced by fermentation of sugars from renewable feedstocks, such as plant biomass. Bio-based succinic acid has great potential in becoming a platform chemical (building block) for commodity and high-value chemicals. In this study, the production of bio-based succinic acid from sweet sorghum was investigated. Sweet sorghum has high fermentable sugar content and can be cultivated in a variety of climates. In order to avoid competition with food feedstocks, its non-edible ‘bagasse’ (the fiber part after extracting the juice) was targeted. Initially, various conditions of pretreating sweet sorghum bagasse (SSB) were studied in an effort to remove most of the non-fermentable components and expose the cellulosic fiber containing the fermentable sugars (glucose). Concentrated (83%) phosphoric acid was utilized at temperatures 50-80 oC for 30-60 min at various SSB loadings (10-15%), coupled with enzymatic hydrolysis using commercial cellulase (Ctec2, Novozymes) enzyme, to identify the conditions that lead to the highest glucose yields for subsequent fermentation to succinic acid. As the pretreatment temperature and duration increased, the bagasse color changed from light brown to dark brown-black, indicating decomposition, which ranged from 15% to 72%, while the theoretical glucose yield is 91%. With Minitab software statistical analysis, a model was built to identify the optimal pretreatment condition for maximum glucose released. The projected theoretical bio-based succinic acid production is 23g per 100g of SSB, which will be confirmed with fermentation experiments using the bacterium Actinobacillus succinogenes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose" title=" cellulose"> cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymatic%20hydrolysis" title=" enzymatic hydrolysis"> enzymatic hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=pretreatment" title=" pretreatment"> pretreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=succinic%20acid" title=" succinic acid"> succinic acid</a> </p> <a href="https://publications.waset.org/abstracts/72626/conversion-of-sweet-sorghum-bagasse-to-sugars-for-succinic-acid-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72626.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> An Overview of Technology Availability to Support Remote Decentralized Clinical Trials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simone%20Huber">Simone Huber</a>, <a href="https://publications.waset.org/abstracts/search?q=Bianca%20Schnalzer"> Bianca Schnalzer</a>, <a href="https://publications.waset.org/abstracts/search?q=Baptiste%20Alcalde"> Baptiste Alcalde</a>, <a href="https://publications.waset.org/abstracts/search?q=Sten%20Hanke"> Sten Hanke</a>, <a href="https://publications.waset.org/abstracts/search?q=Lampros%20Mpaltadoros"> Lampros Mpaltadoros</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanos%20G.%20Stavropoulos"> Thanos G.

For their success, recruitment and retention of participants are some of the most challenging aspects of protocol adherence. Main barriers include: i) lack of awareness of clinical trials; ii) long distance from the clinical site; iii) the burden on participants, including the duration and number of clinical visits and iv) high dropout rate. Most of these aspects could be addressed with a new paradigm, namely the Remote Decentralized Clinical Trials (RDCTs). Furthermore, the COVID-19 pandemic has highlighted additional advantages and challenges for RDCTs in practice, allowing participants to join trials from home and not depend on site visits, etc. Nevertheless, RDCTs should follow the process and the quality assurance of conventional clinical trials, which involve several processes. For each part of the trial, the Building Blocks, existing software and technologies were assessed through a systematic search. The technology needed to perform RDCTs is widely available and validated but is yet segmented and developed in silos, as different software solutions address different parts of the trial and at various levels. The current paper is analyzing the availability of technology to perform RDCTs, identifying gaps and providing an overview of Basic Building Blocks and functionalities that need to be covered to support the described processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architectures%20and%20frameworks%20for%20health%20informatics%20systems" title="architectures and frameworks for health informatics systems">architectures and frameworks for health informatics systems</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20trials" title=" clinical trials"> clinical trials</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20and%20communications%20technology" title=" information and communications technology"> information and communications technology</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20decentralized%20clinical%20trials" title=" remote decentralized clinical trials"> remote decentralized clinical trials</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20availability" title=" technology availability"> technology availability</a> </p> <a href="https://publications.waset.org/abstracts/140144/an-overview-of-technology-availability-to-support-remote-decentralized-clinical-trials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140144.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">217</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Different Types of Amyloidosis Revealed with Positive Cardiac Scintigraphy with Tc-99M DPD-SPECT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Panagiotopoulos">Ioannis Panagiotopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Efstathios%20Kastritis"> Efstathios Kastritis</a>, <a href="https://publications.waset.org/abstracts/search?q=Anastasia%20Katinioti"> Anastasia Katinioti</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgios%20Efthymiadis"> Georgios Efthymiadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Argyrios%20Doumas"> Argyrios Doumas</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Koutelou"> Maria Koutelou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Transthyretin amyloidosis (ATTR) is a rare but serious infiltrative disease. Myocardial scintigraphy with DPD has emerged as the most effective, non-invasive, highly sensitive, and highly specific diagnostic method for cardiac ATTR amyloidosis. However, there are cases in which additional laboratory investigations reveal AL amyloidosis or other diseases despite a positive DPD scintigraphy. We describe the experience from the Onassis Cardiac Surgery Center and the monitoring center for infiltrative myocardial diseases of the cardiology clinic at AHEPA. Materials and Methods: All patients with clinical suspicion of cardiac or extracardiac amyloidosis undergo a myocardial scintigraphy scan with Tc-99m DPD. In this way, over 500 patients have been examined. Further diagnostic approach based on clinical and imaging findings includes laboratory investigation and invasive techniques (e.g., biopsy). Results: Out of 76 patients in total with positive myocardial scintigraphy Grade 2 or 3 according to the Perugini scale, 8 were proven to suffer from AL Amyloidosis during the investigation of paraproteinemia. Among these patients, 3 showed Grade 3 uptake, while the rest were graded as Grade 2, or 2 to 3. Additionally, one patient presented diffuse and unusual radiopharmaceutical uptake in soft tissues throughout the body without cardiac involvement. These findings raised suspicions, leading to the analysis of κ and λ light chains in the serum, as well as immunostaining of proteins in the serum and urine of these specific patients. The final diagnosis was AL amyloidosis. Conclusion: The value of DPD scintigraphy in the diagnosis of cardiac amyloidosis from transthyretin is undisputed. However, positive myocardial scintigraphy with DPD should not automatically lead to the diagnosis of ATTR amyloidosis. Laboratory differentiation between ATTR and AL amyloidosis is crucial, as both prognosis and therapeutic strategy are dramatically altered. Laboratory exclusion of paraproteinemia is a necessary and essential step in the diagnostic algorithm of ATTR amyloidosis for all positive myocardial scintigraphy with diphosphonate tracers since >20% of patients with Grade 3 and 2 uptake may conceal AL amyloidosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AL%20amyloidosis" title="AL amyloidosis">AL amyloidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=amyloidosis" title=" amyloidosis"> amyloidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ATTR" title=" ATTR"> ATTR</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20scintigraphy" title=" myocardial scintigraphy"> myocardial scintigraphy</a>, <a href="https://publications.waset.org/abstracts/search?q=Tc-99m%20DPD" title=" Tc-99m DPD"> Tc-99m DPD</a> </p> <a href="https://publications.waset.org/abstracts/176715/different-types-of-amyloidosis-revealed-with-positive-cardiac-scintigraphy-with-tc-99m-dpd-spect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176715.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Detection of Flood Prone Areas Using Multi Criteria Evaluation, Geographical Information Systems and Fuzzy Logic.

It has been observed that floods affect the greatest number of people and induce the biggest damage when compared to the total of annual natural disasters. The detection of potential flood-prone areas constitutes one of the fundamental components of the European Natural Disaster Management Policy, directly connected to the European Directive 2007/60. The aim of the present paper is to develop a new methodology that combines geographical information, fuzzy logic and multi-criteria evaluation methods so that the most vulnerable areas are defined. Therefore, ten factors related to geophysical, morphological, climatological/meteorological and hydrological characteristics of the basin were selected. Afterwards, two models were created to detect the areas pronest to flooding. The first model defined the gravitas of each factor using Analytical Hierarchy Process (AHP) and the final map of possible flood spots were created using GIS and Boolean Algebra. The second model made use of the fuzzy logic and GIS combination and a respective map was created. The application area of the aforementioned methodologies was in Ardas basin due to the frequent and important floods that have taken place these last years. Then, the results were compared to the already observed floods. The result analysis shows that both models can detect with great precision possible flood spots. As the fuzzy logic model is less time-consuming, it is considered the ideal model to apply to other areas. The said results are capable of contributing to the delineation of high risk areas and to the creation of successful management plans dealing with floods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process" title="analytical hierarchy process">analytical hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20prone%20areas" title=" flood prone areas"> flood prone areas</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20information%20system" title=" geographic information system"> geographic information system</a> </p> <a href="https://publications.waset.org/abstracts/37019/detection-of-flood-prone-areas-using-multi-criteria-evaluation-geographical-information-systems-and-fuzzy-logic-the-ardas-basin-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37019.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">379</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> A Six-Year Case Study Evaluating the Stakeholders’ Requirements and Satisfaction in Higher Educational Establishments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20I.%20%CE%91ngeli">Ioannis I.

All systems are targeting to measure or evaluate the Universities’ Quality Assurance Systems and the services offered to the recipients of HE, mainly the students. Numerous surveys were conducted in the past either by each university or by organized bodies to identify the students’ satisfaction or to evaluate to what extent these requirements are fulfilled. In this paper, the main results of an ongoing 6-year joint research will be presented very briefly. This research deals with an in depth investigation of student’s satisfaction, students personal requirements, a cup analysis among these two parameters and compares different universities. Through this research an attempt will be made to address four very important questions in higher education establishments (HEE): (1) Are there any common requirements, parameters, good practices or questions that apply to a large number of universities that will assure that students’ requirements are fulfilled? (2) Up to what extent the individual programs of HEE fulfil the requirements of the stakeholders? (3) Are there any similarities on specific programs among European HEE? (4) To what extent the knowledge acquired in a specific course program is utilized or used in a specific country? For the execution of the research an internationally accepted questionnaire(s) was used to evaluate up to what extent the students’ requirements and satisfaction were fulfilled in 2012 and five years later (2017). Samples of students and or universities were taken from many European Universities. The questionnaires used, the sampling method and methodology adopted, as well as the comparison tables and results will be very valuable to any university that is willing to follow the same route and methodology or compare the results with their own HHE. Apart from the unique methodology, valuable results are demonstrated from the four case studies. There is a great difference between the student’s expectations or importance from what they are getting from their universities (in all parameters they are getting less). When there is a crisis or budget cut in HEE there is a direct impact to students. There are many differences on subjects taught in European universities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20in%20higher%20education" title="quality in higher education">quality in higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=students%27%20requirements" title=" students' requirements"> students' requirements</a>, <a href="https://publications.waset.org/abstracts/search?q=education%20standards" title=" education standards"> education standards</a>, <a href="https://publications.waset.org/abstracts/search?q=student%27s%20survey" title=" student's survey"> student's survey</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholder%27s%20requirements" title=" stakeholder's requirements"> stakeholder's requirements</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20engineering%20courses" title=" mechanical engineering courses"> mechanical engineering courses</a> </p> <a href="https://publications.waset.org/abstracts/99932/a-six-year-case-study-evaluating-the-stakeholders-requirements-and-satisfaction-in-higher-educational-establishments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99932.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Legal Issues of Collecting and Processing Big Health Data in the Light of European Regulation 679/2016</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Iglezakis">Ioannis Iglezakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Theodoros%20D.%20Trokanas"> Theodoros D.

Whether Big Health Data can be characterised as ‘personal data’ or not is really the crux of the matter. The legal ambiguity is compounded by the fact that, even though the processing of Big Health Data is premised on the de-identification of the data subject, the possibility of a combination of Big Health Data with other data circulating freely on the web or from other data files cannot be excluded. Another key point is that the application of some provisions of GPDR to Big Health Data may both absolve the data controller of his legal obligations and deprive the data subject of his rights (e.g., the right to be informed), ultimately undermining the fundamental right to the protection of personal data of natural persons. Moreover, data subject’s rights (e.g., the right not to be subject to a decision based solely on automated processing) are heavily impacted by the use of AI, algorithms, and technologies that reclaim health data for further use, resulting in sometimes ambiguous results that have a substantial impact on individuals. On the other hand, as the COVID-19 pandemic has revealed, Big Data analytics can offer crucial sources of information. In this respect, this paper identifies and systematises the legal provisions concerned, offering interpretative solutions that tackle dangers concerning data subject’s rights while embracing the opportunities that Big Health Data has to offer. In addition, particular attention is attached to the scope of ‘consent’ as a legal basis in the collection and processing of Big Health Data, as the application of data analytics in Big Health Data signals the construction of new data and subject’s profiles. Finally, the paper addresses the knotty problem of role assignment (i.e., distinguishing between controller and processor/joint controllers and joint processors) in an era of extensive Big Health data sharing. The findings are the fruit of a current research project conducted by a three-member research team at the Faculty of Law of the Aristotle University of Thessaloniki and funded by the Greek Ministry of Education and Religious Affairs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20health%20data" title="big health data">big health
