This approach, based on a two-cluster Fuzzy C-Means methodology, considers type-II fuzzy sets to handle uncertainty due to the image modality (presence of speckle noise, low contrast, etc.), and to calculate the optimum inter-cluster threshold. Fine boundaries are detected by a local recursive merging of ambiguous pixels. The method has been tested on a representative database. Compared to both Otsu and type-I Fuzzy C-Means techniques, the proposed method significantly reduces the segmentation errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=defuzzification" title="defuzzification">defuzzification</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20clustering" title=" fuzzy clustering"> fuzzy clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20segmentation" title=" image segmentation"> image segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=type-II%20fuzzy%20sets" title=" type-II fuzzy sets"> type-II fuzzy sets</a> </p> <a href="https://publications.waset.org/abstracts/32293/liver-lesion-extraction-with-fuzzy-thresholding-in-contrast-enhanced-ultrasound-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32293.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">485</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">51</span> Trends in All-Cause Mortality and Inpatient and Outpatient Visits for Ambulatory Care Sensitive Conditions during the First Year of the COVID-19 Pandemic: A Population-Based Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tetyana%20Kendzerska">Tetyana Kendzerska</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20T.%20Zhu"> David T.

To compare observed and expected (projected based on previous years) trends in all-cause mortality and healthcare use for ACSCs in the first year of the pandemic (March 2020 - March 2021). A population-based study using provincial health administrative data.General adult population (Ontario, Canada). Monthly all-cause mortality, and hospitalizations, emergency department (ED) and outpatient visit rates (per 100,000 people at-risk) for seven combined ACSCs (asthma, COPD, angina, congestive heart failure, hypertension, diabetes, and epilepsy) during the first year were compared with similar periods in previous years (2016-2019) by fitting monthly time series auto-regressive integrated moving-average models. Compared to previous years, all-cause mortality rates increased at the beginning of the pandemic (observed rate in March-May 2020 of 79.98 vs. projected of 71.24 [66.35-76.50]) and then returned to expected in June 2020—except among immigrants and people with mental health conditions where they remained elevated. Hospitalization and ED visit rates for ACSCs remained lower than projected throughout the first year: observed hospitalization rate of 37.29 vs. projected of 52.07 (47.84-56.68); observed ED visit rate of 92.55 vs. projected of 134.72 (124.89-145.33). ACSC outpatient visit rates decreased initially (observed rate of 4,299.57 vs. projected of 5,060.23 [4,712.64-5,433.46]) and then returned to expected in June 2020. Reductions in outpatient visits for ACSCs at the beginning of the pandemic combined with reduced hospital admissions may have been associated with temporally increased mortality—disproportionately experienced by immigrants and those with mental health conditions.

One such challenge is coping with the stress and negative emotions of caregiving. The Stoics (i.e. Lucius Annaeus Seneca [4 B.C.E. - 65 C.E.], Epictetus [50-135 C.E.], and Marcus Aurelius [121-180 C.E.]) have provided coping techniques that are useful for dealing with stress and negative emotions. This paper lists and explains some of the fundamental coping techniques provided by the Stoics. For instance, some Stoic coping techniques thus follow (the list is far from exhaustive): a) mindfulness: to the best of your ability, constantly being aware of your thoughts, habits, desires, norms, memories, likes/dislikes, beliefs, values, and of everything outside of you in the world (b) constantly adjusting one’s expectations in accordance with reality, c) memento mori: constantly reminding oneself that death is inevitable and that death is not to be seen as evil, and d) praemeditatio malorum: constantly detaching oneself from everything that is so dear to one so that the least amount of suffering follows from the loss, damage, or ceasing to be of such entities. All coping techniques will be extracted from the following original texts by the Stoics: Seneca’s Letters to Lucilius, Epictetus’ Discourses and the Encheiridion, and Marcus Aurelius’ Meditations. One major finding is that the usefulness of each Stoic coping technique can be empirically tested by anyone in the sense of applying it one’s own life especially when one is facing real-life challenges. Another major finding is that all of the Stoic coping techniques are predicated upon, and follow from, one fundamental principle: constantly differentiate what is and what is not in one’s control. After differentiating it, one should constantly habituate oneself in not controlling things that are beyond one’s control. For example, the following things are beyond one’s control (all things being equal): death, certain illnesses, being born in a particular socio-economic family, etc. The conclusion is that if one habituates oneself by practicing to the best of one’s ability both the fundamental Stoic principle and the Stoic coping techniques, then such a habitual practice can eventually decrease the stress and negative emotions that one experiences by being a caregiver. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=care-giving" title="care-giving">care-giving</a>, <a href="https://publications.waset.org/abstracts/search?q=coping%20techniques" title=" coping techniques"> coping techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20emotions" title=" negative emotions"> negative emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=stoicism" title=" stoicism"> stoicism</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/88621/coping-with-the-stress-and-negative-emotions-of-care-giving-by-using-techniques-from-seneca-epictetus-and-marcus-aurelius" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88621.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">49</span> Lexical Classification of Compounds in Berom: A Semantic Description of N-V Nominal Compounds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pam%20Bitrus%20Marcus">Pam Bitrus Marcus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compounds in Berom, a Niger-Congo language that is spoken in parts of central Nigeria, have been understudied, and the semantics of N-V nominal compounds have not been sufficiently delineated. This study describes the lexical classification of compounds in Berom and, specifically, examines the semantics of nominal compounds with N-V constituents. The study relied on a data set of 200 compounds that were drawn from Bere Naha (a newsletter publication in Berom). Contrary to the nominalization process in defining the lexical class of compounds in languages, the study revealed that verbal and adjectival classes of compounds are also attested in Berom and N-V nominal compounds have an agentive or locative interpretation that is not solely determined by the meaning of the constituents of the compound but by the context of the usage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=berom" title="berom">berom</a>, <a href="https://publications.waset.org/abstracts/search?q=berom%20compounds" title=" berom compounds"> berom compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=nominal%20compound" title=" nominal compound"> nominal compound</a>, <a href="https://publications.waset.org/abstracts/search?q=N-V%20compounds" title=" N-V compounds"> N-V compounds</a> </p> <a href="https://publications.waset.org/abstracts/171026/lexical-classification-of-compounds-in-berom-a-semantic-description-of-n-v-nominal-compounds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171026.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">78</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">48</span> Conductive and Stretchable Graphene Nanoribbon Coated Textiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%20Gan">Lu Gan</a>, <a href="https://publications.waset.org/abstracts/search?q=Songmin%20Shang"> Songmin Shang</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Chun%20Wah%20Yuen"> Marcus Chun Wah Yuen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A conductive and stretchable cotton fabric was prepared in this study through coating the graphene nanoribbon onto the cotton fabric.

Central to the methodologies are the presumption that it is the absolute yield of the crop in a given location that is of the highest priority to those requiring information on crop productivity. Most individuals, companies and organisations within the agri-food sector need to be able to balance the supply of crops with the demand for them. Different modelling approaches have been used to determine and predict crop yield. The growing need to ensure certainty of supply and stability of prices requires an approach that describes the risk in producing a crop.

The estimator only needs a few, usually known, steering system parameters. Friction occurs on almost every mechanical system and has a negative influence on high-precision position control. This is demonstrated on a steering angle controller for highly automated driving. In this steering system the friction induces limit cycles which cause oscillating vehicle movement when the vehicle follows a given reference trajectory. When compensating the friction with the introduced estimator, limit cycles can be suppressed. This is demonstrated by measurements in a series vehicle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20estimation" title="friction estimation">friction estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20compensation" title=" friction compensation"> friction compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=steering%20system" title=" steering system"> steering system</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20vehicle%20guidance" title=" lateral vehicle guidance"> lateral vehicle guidance</a> </p> <a href="https://publications.waset.org/abstracts/27641/friction-estimation-and-compensation-for-steering-angle-control-for-highly-automated-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27641.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">515</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">45</span> Global Direct Search Optimization of a Tuned Liquid Column Damper Subject to Stochastic Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mansour%20H.%20Alkmim">Mansour H.

The objective is to find optimized parameters for the TLCD under stochastic load from different wind power spectral density. A verification is made considering the analytical solution of an undamped primary system under white noise excitation. Finally, a numerical example considering a simplified wind turbine model is given to illustrate the efficacy of the TLCD. Results from the random vibration analysis are shown for four types of random excitation wind model where the response PSDs obtained showed good vibration attenuation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generalized%20pattern%20search" title="generalized pattern search">generalized pattern search</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20optimization" title=" parameter optimization"> parameter optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20vibration%20analysis" title=" random vibration analysis"> random vibration analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20suppression" title=" vibration suppression"> vibration suppression</a> </p> <a href="https://publications.waset.org/abstracts/68674/global-direct-search-optimization-of-a-tuned-liquid-column-damper-subject-to-stochastic-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68674.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">275</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">44</span> National Strategy for Swedish Wildlife Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Hornell">Maria Hornell</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Ohman"> Marcus Ohman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nature, and the society it is a part of, is under constant change. The landscape, climate and game populations vary over time, as well as society's priorities and the way it uses the land where wildlife may proliferate. Sweden currently has historically large wildlife populations which are a resource for the benefit and joy of many people. Wildlife may also be seen as a problem as it may cause damage in contradiction to other human interests. The Swedish Environmental Protection Agency introduces a new long-term strategy for national wildlife management. The strategy envisions a wildlife management in balance. It focuses on wildlife values in a broad sense including outdoor recreation and tourism as well as conservation of biodiversity. It is fundamental that these values should be open and accessible for the major part of the population. For that to be possible new ways to manage, mitigate and prevent damages and other problems that wildlife causes need to be developed. The strategy describes a roadmap for the development and strengthening of Sweden's wildlife management until 2020. It aims at being applicable for those authorities and stakeholders with interest in wildlife management being a guide for their own strategies, goals, and activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wildlife%20management" title="wildlife management">wildlife management</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sweden" title=" Sweden"> Sweden</a>, <a href="https://publications.waset.org/abstracts/search?q=SEPA" title=" SEPA"> SEPA</a> </p> <a href="https://publications.waset.org/abstracts/88146/national-strategy-for-swedish-wildlife-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88146.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">43</span> Jordan Curves in the Digital Plane with Respect to the Connectednesses given by Certain Adjacency Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Josef%20Slapal">Josef Slapal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital images are approximations of real ones and, therefore, to be able to study them, we need the digital plane Z2 to be equipped with a convenient structure that behaves analogously to the Euclidean topology on the real plane. In particular, it is required that such a structure allows for a digital analogue of the Jordan curve theorem. We introduce certain adjacency graphs on the digital plane and prove digital Jordan curves for them thus showing that the graphs provide convenient structures on Z2 for the study and processing of digital images. Further convenient structures including the wellknown Khalimsky and Marcus-Wyse adjacency graphs may be obtained as quotients of the graphs introduced. Since digital Jordan curves represent borders of objects in digital images, the adjacency graphs discussed may be used as background structures on the digital plane for solving the problems of digital image processing that are closely related to borders like border detection, contour filling, pattern recognition, thinning, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20plane" title="digital plane">digital plane</a>, <a href="https://publications.waset.org/abstracts/search?q=adjacency%20graph" title=" adjacency graph"> adjacency graph</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan%20curve" title=" Jordan curve"> Jordan curve</a>, <a href="https://publications.waset.org/abstracts/search?q=quotient%20adjacency" title=" quotient adjacency"> quotient adjacency</a> </p> <a href="https://publications.waset.org/abstracts/65454/jordan-curves-in-the-digital-plane-with-respect-to-the-connectednesses-given-by-certain-adjacency-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65454.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">42</span> Laser Micro-Welding of an Isomorphous System with Different Geometries: An Investigation on the Mechanical Properties and Microstructure of the Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Amne%20Elahi">Mahdi Amne Elahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Koch"> Marcus Koch</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Plapper"> Peter Plapper</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the demand of miniaturizing in automotive industry, the application of laser welding is quite promising. The current study focused on laser micro-welding of CuSn6 bronze and nickel wire for a miniature electromechanical hybrid component. Due to the advantages of laser welding, the welding can be tailored specifically for the requirements of the part. Scanning electron and optical microscopy were implemented to study the microstructure and tensile-shear test was selected to represent the mechanical properties. Different welding sides, beam oscillations, and speeds have been investigated to optimize the tensile-shear load and microstructure. The results show that the mechanical properties and microstructure of the joint is highly under the influence of the mentioned parameters. Due to the lack of intermetallic compounds, the soundness of the joint is achievable by manipulating the geometry of the weld seam and minimize weld defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bronze" title="bronze">bronze</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20micro-welding" title=" laser micro-welding"> laser micro-welding</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel" title=" nickel"> nickel</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20shear%20test" title=" tensile shear test"> tensile shear test</a> </p> <a href="https://publications.waset.org/abstracts/103859/laser-micro-welding-of-an-isomorphous-system-with-different-geometries-an-investigation-on-the-mechanical-properties-and-microstructure-of-the-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103859.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">166</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> Use of Natural Fibers in Landfill Leachate Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Araujo%20J.%20F.%20Marina">Araujo J.

In seeking to improve this situation, this project proposes the treatment of landfill leachate using natural fibers intercropped with advanced oxidation processes. The selected natural fibers were palm, coconut and banana fiber. These materials give sustainability to the project because, besides having adsorbent capacity, are often part of waste discarded. The study was conducted in laboratory scale. In trials, the effluents were characterized as Chemical Oxygen Demand (COD), Turbidity and Color. The results indicate that is technically promising since that there were extremely oxidative conditions, the use of certain natural fibers in the reduction of pollutants in leachate have been obtained results of COD removals between 67.9% and 90.9%, Turbidity between 88.0% and 99.7% and Color between 67.4% and 90.4%. The expectation generated is to continue evaluating the association of efficiency of other natural fibers with other landfill leachate treatment processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lndfill%20leachate" title="lndfill leachate">lndfill leachate</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20treatment" title=" chemical treatment"> chemical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20fibers" title=" natural fibers"> natural fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20oxidation%20processes" title=" advanced oxidation processes"> advanced oxidation processes</a> </p> <a href="https://publications.waset.org/abstracts/27165/use-of-natural-fibers-in-landfill-leachate-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27165.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">40</span> Shotcrete Performance Optimisation and Audit Using 3D Laser Scanning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Gonzalez">Carlos Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Slatcher"> Neil Slatcher</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20%20Properzi"> Marcus Properzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kan%20Seah"> Kan Seah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In many underground mining operations, shotcrete is used for permanent rock support. Shotcrete thickness is a critical measure of the success of this process. 3D Laser Mapping, in conjunction with Jetcrete, has developed a 3D laser scanning system specifically for measuring the thickness of shotcrete. The system is mounted on the shotcrete spraying machine and measures the rock faces before and after spraying. The calculated difference between the two 3D surface models is measured as the thickness of the sprayed concrete. Typical work patterns for the shotcrete process required a rapid and automatic system. The scanning takes place immediately before and after the application of the shotcrete so no convergence takes place in the interval between scans. Automatic alignment of scans without targets was implemented which allows for the possibility of movement of the spraying machine between scans. Case studies are presented where accuracy tests are undertaken and automatic audit reports are calculated. The use of 3D imaging data for the calculation of shotcrete thickness is an important tool for geotechnical engineers and contract managers, and this could become the new state-of-the-art methodology for the mining industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20imaging" title="3D imaging">3D imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=shotcrete" title=" shotcrete"> shotcrete</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20model" title=" surface model"> surface model</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel%20stability" title=" tunnel stability"> tunnel stability</a> </p> <a href="https://publications.waset.org/abstracts/84408/shotcrete-performance-optimisation-and-audit-using-3d-laser-scanning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84408.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">290</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">39</span> Component Interface Formalization in Robotic Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20Hristozov">Anton Hristozov</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Matson"> Eric Matson</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Dietz"> Eric Dietz</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Rogers"> Marcus Rogers</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Components are heavily used in many software systems, including robotics systems. The growth of sophistication and diversity of new capabilities for robotic systems presents new challenges to their architectures. Their complexity is growing exponentially with the advent of AI, smart sensors, and the complex tasks they have to accomplish. Such complexity requires a more rigorous approach to the creation, use, and interoperability of software components. The issue is exacerbated because robotic systems are becoming more and more reliant on third-party components for certain functions. In order to achieve this kind of interoperability, including dynamic component replacement, we need a way to standardize their interfaces. A formal approach is desperately needed to specify what an interface of a robotic software component should contain. This study performs an analysis of the issue and presents a universal and generic approach to standardizing component interfaces for robotic systems. Our approach is inspired by well-established robotic architectures such as ROS, PX4, and Ardupilot. The study is also applicable to other software systems that share similar characteristics with robotic systems. We consider the use of JSON or Domain Specific Languages (DSL) development with tools such as Antlr and automatic code and configuration file generation for frameworks such as ROS and PX4. A case study with ROS2 is presented as a proof of concept for the proposed methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CPS" title="CPS">CPS</a>, <a href="https://publications.waset.org/abstracts/search?q=robots" title=" robots"> robots</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20architecture" title=" software architecture"> software architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=interface" title=" interface"> interface</a>, <a href="https://publications.waset.org/abstracts/search?q=ROS" title=" ROS"> ROS</a>, <a href="https://publications.waset.org/abstracts/search?q=autopilot" title=" autopilot"> autopilot</a> </p> <a href="https://publications.waset.org/abstracts/148295/component-interface-formalization-in-robotic-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148295.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">92</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> An International Comparison of Forensic Identification Evidence Legislation: Balancing Community Interests and Individual Rights</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Smith">Marcus Smith</a> </p> <p class="card-text"><strong>Abstract:</strong></p> DNA profiling has made a valuable contribution to criminal investigations over the past thirty years. Direct matching DNA profiles from a crime scene and suspect, or between a suspect and a database remain of great importance to crimes such as murder, assault, and property theft. As scientific and technological advancement continues, a wide range of new DNA profiling applications has been developed. The application of new techniques involves an interesting balancing act between admitting probative evidence in a criminal trial, evaluating its degree of relevance and validity, and limiting its prejudicial impact. The impact of new DNA profiling applications that have significant implications for law enforcement and the legal system can be evaluated through a review of relevant case law, legislation and the latest empirical evidence from jurisdictions around the world including the United States, United Kingdom, and Australia. There are benefits in further examining the implications of these new developments, including how the criminal law can best be adapted to ensure that new technology is used to enhance criminal investigation and prosecution while ensuring it is applied in a measured way that respects individual rights and maintains principles of fairness enshrined in the legal system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criminal%20procedure" title="criminal procedure">criminal procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20evidence" title=" forensic evidence"> forensic evidence</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20profiling" title=" DNA profiling"> DNA profiling</a>, <a href="https://publications.waset.org/abstracts/search?q=familial%20searching" title=" familial searching"> familial searching</a>, <a href="https://publications.waset.org/abstracts/search?q=phenotyping" title=" phenotyping"> phenotyping</a> </p> <a href="https://publications.waset.org/abstracts/83037/an-international-comparison-of-forensic-identification-evidence-legislation-balancing-community-interests-and-individual-rights" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83037.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">132</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">37</span> Shoring System Selection for Deep Excavation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faouzi%20Ahtchi-Ali">Faouzi Ahtchi-Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Vitiello"> Marcus Vitiello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A study was conducted in the east region of the Middle East to assess the constructability of a shoring system for a 12-meter deep excavation. Several shoring systems were considered in this study including secant concrete piling, contiguous concrete piling, and sheet-piling. The excavation was carried out in a very dense sand with the groundwater level located at 3 meters below ground surface. The study included conducting a pilot test for each shoring system listed above. The secant concrete piling included overlapping concrete piles to a depth of 16 meters. Drilling method with full steel casing was utilized to install the concrete piles. The verticality of the piles was a concern for the overlap. The contiguous concrete piling required the installation of micro-piles to seal the gap between the concrete piles. This method revealed that the gap between the piles was not fully sealed as observed by the groundwater penetration to the excavation. The sheet-piling method required pre-drilling due to the high blow count of the penetrated layer of saturated sand. This study concluded that the sheet-piling method with pre-drilling was the most cost effective and recommended a method for the shoring system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=excavation" title="excavation">excavation</a>, <a href="https://publications.waset.org/abstracts/search?q=shoring%20system" title=" shoring system"> shoring system</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20east" title=" middle east"> middle east</a>, <a href="https://publications.waset.org/abstracts/search?q=Drilling%20method" title=" Drilling method"> Drilling method</a> </p> <a href="https://publications.waset.org/abstracts/21043/shoring-system-selection-for-deep-excavation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21043.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">468</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> FELIX: 40 Hz Masked Flickering Light as a Potential Treatment of Major Depressive Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikolas%20Aasheim">Nikolas Aasheim</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Sakalauskait%C4%97"> Laura Sakalauskaitė</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Dubois"> Julie Dubois</a>, <a href="https://publications.waset.org/abstracts/search?q=Malina%20Ploug%20Larsen"> Malina Ploug Larsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Michael%20Petersen"> Paul Michael Petersen</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20S.%20Carstensen"> Marcus S.

Current treatments are based on a trial-and-error approach, and reliable biomarkers are needed for more informed and personalized treatment solutions. One potential biomarker is aberrant gamma-frequency (30-80 Hz) brainwaves, hypothesized to originate from deficiencies in the excitatory-inhibitory interaction between the pyramidal cells and interneurons. An imbalance within this interaction is described as a crucial pathological mechanism in various neuropsychiatric conditions, including MDD, and the modulation of this pathological interaction has been investigated as a potential target. A specific type of steady-state visually evoked potential (SSVEP) in the gamma frequency band, referred to as gamma entrainment using sensory stimuli (GENUS), particularly around the 40Hz spectrum, entrains large scale, fast-spiking PV+ interneurons, facilitating coordinated activity in key brain regions, reduced neuronal and synaptic loss, and enhanced synaptic stability and plasticity. GENUS has shown promise in improving sleep, offering neuroprotective effects in Alzheimer's disease (AD), and reducing pathological markers like Amyloid Beta and TAU proteins, as seen in animal models. In this study, we explore the antidepressant, cognitive, and electrophysiological effects of a novel, non-invasive brain stimulation (NIBS) approach utilizing a 40 Hz invisible spectral flicker to induce gamma activity in patients diagnosed with Major Depressive Disorder (MDD). This non-invasive targeted stimulation of lower gamma band activity (40 Hz) is designed to modulate neural circuits associated with mood and cognitive functions, providing a potential new therapeutic avenue for MDD. Methods and Design: 60 patients with a current diagnosis of a major depressive episode will be enrolled in a randomized, double-blinded, placebo-controlled trial. The active treatment group will receive 40 Hz invisible spectral flickering light stimulation while the control group will receive continuous light matched in colour temperature and brightness. Patients in both groups will get an hour of daily light treatment in their own homes and will attend four follow-up visits to assess depression severity measured by Hamilton Depression Rating Scale (HAM-D₆), several aspects of sleep, cognitive function, quality of life. Additionally, exploratory EEG is conducted to assess spectral changes throughout the protocol. The primary endpoint is the mean change from baseline to week 6 in depression severity (HAM-D₆ subset) between the groups. Current state of affairs/timeline: The FELIX study was initiated in the beginning of 2022, planning to reach stage of publication in December 2025. 21 participants have been enrolled in the protocol thus far, expecting to be finished with trials and recruitment by the end of 2024. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=major%20depressive%20disorder" title="major depressive disorder">major depressive disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma" title=" gamma"> gamma</a>, <a href="https://publications.waset.org/abstracts/search?q=neurostimulation" title=" neurostimulation"> neurostimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a> </p> <a href="https://publications.waset.org/abstracts/194887/felix-40-hz-masked-flickering-light-as-a-potential-treatment-of-major-depressive-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194887.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">3</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> Seasonal Influence on Environmental Indicators of Beach Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcus%20C.%20Garcia">Marcus C.

The purpose of this paper was to perform a quali-quantitative analysis of the beach waste on the Curva da Jurema Beach (Espírito Santo - Brazil). Three transects were used with equidistant positioning over the total length of the beach for the solid waste collection. Solid wastes were later classified according to their use and primary raw material from the low and high summer season. During the low season, average values of 7.10 items.m<sup>-1</sup>, 18.22 g.m<sup>-1</sup> and 0.91 g.m<sup>-2</sup> were found for the whole beach, and transect 3 contributed the most waste, with the total sum of items equal to 999 (49%), a total mass of 5.62 kg and a total volume of 21.31 L. During the high summer season, average values of 8.22 items.m<sup>-1</sup>, 54.40 g.m<sup>-1</sup> and 2.72 g.m<sup>-2</sup> were found, with transect 2 contributing the most to the total sum with 1,212 items (53%), a total mass of 10.76 kg and a total volume of 51.99 L. Of the total collected, plastic materials represented 51.4% of the total number of items, 35.9% of the total mass and 68% of the total volume. The implementation of reactive and proactive measures is necessary so that the management of the solid wastes on Curva da Jurema Beach is in accordance with principles of sustainability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beach%20solid%20waste" title="beach solid waste">beach solid waste</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20indicators" title=" environmental indicators"> environmental indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=quali-quantitative%20analysis" title=" quali-quantitative analysis"> quali-quantitative analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a> </p> <a href="https://publications.waset.org/abstracts/60976/seasonal-influence-on-environmental-indicators-of-beach-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60976.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">306</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> Child Rights in the Context of Psychiatric Power</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dmytro%20D.%20Buiadzhy">Dmytro D.

The unresolved mental health problems in childhood are likely to lead individuals to poverty, isolation, and social exclusion as stated by Marcus Richards. Such an approach justifies the involvement of children in the view of supervision and control of power. The discourse, related to the mental health of children, provides a tight impact of family, educational institutions and medical authorities on the child through any manifestations of his psychic, having signs of "abnormality.” Throughout the adult life, the individual continues to feel the pressure of power through legal, political, and economic institutions that also appeal to the mental health regulation. The juvenile law declares the equality of a child and an adult, but in fact simply delegates the powers of parents to impersonal social institutions of the guardianship, education, and social protection. The psychiatric power in this study is considered in accordance with the Michel Foucault’s concept of power as a manifestation of "positive" technologies of power, which include various manifestations of subjectivity, in particular children’s one, in a view of supervision and control of the state power. The main issue disclosed in this paper is how weakening of the parental authority, in the context of legislative ratification of the child rights, strengthens the other forms of power over children, especially the psychiatric power, which justifies and affects the children mancipation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=child%20rights" title="child rights">child rights</a>, <a href="https://publications.waset.org/abstracts/search?q=psychiatric%20power" title=" psychiatric power"> psychiatric power</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse" title=" discourse"> discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=parental%20authority" title=" parental authority"> parental authority</a> </p> <a href="https://publications.waset.org/abstracts/39741/child-rights-in-the-context-of-psychiatric-power" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39741.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">344</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> The Challenge of Characterising Drought Risk in Data Scarce Regions: The Case of the South of Angola</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Limones">Natalia Limones</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Marzo"> Javier Marzo</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Wijnen"> Marcus Wijnen</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleix%20Serrat-Capdevila"> Aleix Serrat-Capdevila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research we developed a structured approach for the detection of areas under the highest levels of drought risk that is suitable for data-scarce environments. The methodology is based on recent scientific outcomes and methods and can be easily adapted to different contexts in successive exercises. The research reviews the history of drought in the south of Angola and characterizes the experienced hazard in the episode from 2012, focusing on the meteorological and the hydrological drought types. Only global open data information coming from modeling or remote sensing was used for the description of the hydroclimatological variables since there is almost no ground data in this part of the country. Also, the study intends to portray the socioeconomic vulnerabilities and the exposure to the phenomenon in the region to fully understand the risk. As a result, a map of the areas under the highest risk in the south of the country is produced, which is one of the main outputs of this work. It was also possible to confirm that the set of indicators used revealed different drought vulnerability profiles in the South of Angola and, as a result, several varieties of priority areas prone to distinctive impacts were recognized. The results demonstrated that most of the region experienced a severe multi-year meteorological drought that triggered an unprecedent exhaustion of the surface water resources, and that the majority of their socioeconomic impacts started soon after the identified onset of these processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drought%20risk" title="drought risk">drought risk</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure" title=" exposure"> exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard" title=" hazard"> hazard</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title=" vulnerability"> vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/138085/the-challenge-of-characterising-drought-risk-in-data-scarce-regions-the-case-of-the-south-of-angola" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138085.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">191</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> Accelerated Molecular Simulation: A Convolution Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jannes%20Quer">Jannes Quer</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Niknejad"> Amir Niknejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Weber"> Marcus Weber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational Drug Design is often based on Molecular Dynamics simulations of molecular systems. Molecular Dynamics can be used to simulate, e.g., the binding and unbinding event of a small drug-like molecule with regard to the active site of an enzyme or a receptor. However, the time-scale of the overall binding event is many orders of magnitude longer than the time-scale of simulation. Thus, there is a need to speed-up molecular simulations. In order to speed up simulations, the molecular dynamics trajectories have to be ”steared” out of local minimizers of the potential energy surface – the so-called metastabilities – of the molecular system. Increasing the kinetic energy (temperature) is one possibility to accelerate simulated processes. However, with temperature the entropy of the molecular system increases, too. But this kind ”stearing” is not directed enough to stear the molecule out of the minimum toward the saddle point. In this article, we give a new mathematical idea, how a potential energy surface can be changed in such a way, that entropy is kept under control while the trajectories are still steared out of the metastabilities. In order to compute the unsteared transition behaviour based on a steared simulation, we propose to use extrapolation methods. In the end we mathematically show, that our method accelerates the simulations along the direction, in which the curvature of the potential energy surface changes the most, i.e., from local minimizers towards saddle points. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extrapolation" title="extrapolation">extrapolation</a>, <a href="https://publications.waset.org/abstracts/search?q=Eyring-Kramers" title=" Eyring-Kramers"> Eyring-Kramers</a>, <a href="https://publications.waset.org/abstracts/search?q=metastability" title=" metastability"> metastability</a>, <a href="https://publications.waset.org/abstracts/search?q=multilevel%20sampling" title=" multilevel sampling"> multilevel sampling</a> </p> <a href="https://publications.waset.org/abstracts/67617/accelerated-molecular-simulation-a-convolution-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67617.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">328</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">31</span> Challenges and Insights by Electrical Characterization of Large Area Graphene Layers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Klein">Marcus Klein</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Grie%C3%9FBach"> Martina GrießBach</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Kupke"> Richard Kupke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current advances in the research and manufacturing of large area graphene layers are promising towards the introduction of this exciting material in the display industry and other applications that benefit from excellent electrical and optical characteristics. New production technologies in the fabrication of flexible displays, touch screens or printed electronics apply graphene layers on non-metal substrates and bring new challenges to the required metrology. Traditional measurement concepts of layer thickness, sheet resistance, and layer uniformity, are difficult to apply to graphene production processes and are often harmful to the product layer. New non-contact sensor concepts are required to adapt to the challenges and even the foreseeable inline production of large area graphene. Dedicated non-contact measurement sensors are a pioneering method to leverage these issues in a large variety of applications, while significantly lowering the costs of development and process setup. Transferred and printed graphene layers can be characterized with high accuracy in a huge measurement range using a very high resolution. Large area graphene mappings are applied for process optimization and for efficient quality control for transfer, doping, annealing and stacking processes. Examples of doped, defected and excellent Graphene are presented as quality images and implications for manufacturers are explained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphene" title="graphene">graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=doping%20and%20defect%20testing" title=" doping and defect testing"> doping and defect testing</a>, <a href="https://publications.waset.org/abstracts/search?q=non-contact%20sheet%20resistance%20measurement" title=" non-contact sheet resistance measurement"> non-contact sheet resistance measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=inline%20metrology" title=" inline metrology"> inline metrology</a> </p> <a href="https://publications.waset.org/abstracts/54544/challenges-and-insights-by-electrical-characterization-of-large-area-graphene-layers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54544.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">307</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> Exploring the Energy Model of Cumulative Grief</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masica%20Jordan%20Alston">Masica Jordan Alston</a>, <a href="https://publications.waset.org/abstracts/search?q=Angela%20N.%20Bullock"> Angela N.

The Energy Model of Cumulative Grief utilizes historic models of grief stage theories. The innovative model is additionally unique due to its focus on cultural responsiveness. The Energy Model of Cumulative Grief helps to train practitioners who work with clients dealing with grief and loss. This paper assists in introducing the world to this innovative model and exploring how this model positively impacted a convenience sample of 140 practitioners and individuals experiencing grief and loss. Respondents participated in Webinars provided by the National Grief and Loss Center of America (NGLCA). Participants in this cross-sectional research design study completed one of three Grief and Loss Surveys created by the Grief and Loss Centers of America. Data analysis for this study was conducted via SPSS and Survey Hero to examine survey results for respondents. Results indicate that the Energy Model of Cumulative Grief was an effective resource for participants in addressing grief and loss. The majority of participants found the Webinars to be helpful and a conduit to providing them with higher levels of hope. The findings suggest that using The Energy Model of Cumulative Grief is effective in providing culturally responsive grief and loss resources to practitioners and clients. There are far reaching implications with the use of technology to provide hope to those suffering from grief and loss worldwide through The Energy Model of Cumulative Grief. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grief" title="grief">grief</a>, <a href="https://publications.waset.org/abstracts/search?q=loss" title=" loss"> loss</a>, <a href="https://publications.waset.org/abstracts/search?q=grief%20energy" title=" grief energy"> grief energy</a>, <a href="https://publications.waset.org/abstracts/search?q=grieving%20brain" title=" grieving brain"> grieving brain</a> </p> <a href="https://publications.waset.org/abstracts/168405/exploring-the-energy-model-of-cumulative-grief" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168405.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">85</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> Eye Tracking Syntax in Language Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Maia">Marcus Maia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study reports and discusses the use of eye tracking qualitative data in reading workshops in Brazilian middle and high schools and in Generative Syntax and Sentence Processing courses at the undergraduate and graduate levels at the Federal University of Rio de Janeiro, respectively. Both endeavors take the sentential level as the proper object to be metacognitively explored in language education (cf. Chomsky, Gallego & Ott, 2019) to develop innate science forming capacity and knowledge of language. In both projects, non-discrepant qualitative eye tracking data collected and quantitatively analyzed in experimental syntax and psycholinguistic studies carried out in Lapex (Experimental Psycholinguistics Laboratory of the Federal University of Rio de Janeiro) were displayed to students as a point of departure, triggering discussions. Classes would generally start with the display of videos showing eye tracking data, such as gaze plots and heatmaps from several studies in Psycholinguistics and Experimental Syntax that we had already developed in our laboratory. The videos usually triggered discussions with students about linguistic and psycholinguistic issues, such as the reading of sentences for gist, garden-path sentences, syntactic and semantic anomalies, the filled-gap effect, island effects, direct and indirect cause, and recursive constructions, among other topics. Active, problem-solving based methodologies were employed with the objective of stimulating student participation. The communication also discusses the importance of developing full literacy, epistemic vigilance and intellectual self-defense in an infodemic world in the lines of Maia (2022). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reading" title="reading">reading</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20psycholinguistics" title=" educational psycholinguistics"> educational psycholinguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=eye-tracking" title=" eye-tracking"> eye-tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20methodology" title=" active methodology"> active methodology</a> </p> <a href="https://publications.waset.org/abstracts/172629/eye-tracking-syntax-in-language-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172629.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">66</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">28</span> Navigating the Ripple Effect: Deconstructing the Multilayered Impact of Fuel Subsidy Removal on Nigeria’s Educational Landscape</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abimbola%20Mobolanle%20Adu">Abimbola Mobolanle Adu</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Tayo%20Akinlade"> Marcus Tayo Akinlade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This comprehensive study systematically dissects the intricate interplay between the removal of fuel subsidy and its multifaceted repercussions on Nigeria's educational system. Originating in the 1970s, the fuel subsidy policy initially conceived to curtail fuel costs and faced financial unsustainability. In 2023, President Bola Tinubu's administration announced its cessation. The resultant escalation in petroleum product prices precipitated challenges within the education sector, manifesting as heightened administrative costs, increased student fees, amplified dropout rates, and others. Employing a qualitative research methodology, grounded in Critical Theory, the study draws from diverse secondary sources and employs content analysis to unravel the intricate layers of this issue. Critical Theory provides a lens through which the power dynamics, socio-economic structures, and ideological influences shaping policy decisions can be critically examined, offering a deeper understanding of the multifaceted impact. Findings underscore the imperative for strategic interventions, advocating for investments in technology and the exploration of alternative energy sources. The paper concludes by emphasizing the pivotal role of education, advocating for nuanced policies to alleviate the impact on both private and public educational institutions. In essence, this research contributes nuanced insights into the labyrinthine dynamics between fuel subsidy policies and the educational sector, underscoring the exigency for meticulous interventions to fortify the nation's educational foundation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=administration" title="administration">administration</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20subsidy" title=" fuel subsidy"> fuel subsidy</a>, <a href="https://publications.waset.org/abstracts/search?q=policy" title=" policy"> policy</a>, <a href="https://publications.waset.org/abstracts/search?q=multilayered%20impact" title=" multilayered impact"> multilayered impact</a> </p> <a href="https://publications.waset.org/abstracts/179338/navigating-the-ripple-effect-deconstructing-the-multilayered-impact-of-fuel-subsidy-removal-on-nigerias-educational-landscape" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179338.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">59</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> Engineering Ligand-Free Biodegradable-Based Nanoparticles for Cell Attachment and Growth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simone%20F.%20Medeiros">Simone F.

Its basic principle is to place cells on a scaffold capable of promoting cell functions, and for this purpose, polymeric nanoparticles have been successfully used due to the ability of some macro chains to mimic the extracellular matrix and influence cell functions. In general, nanoparticles require surface chemical modification to achieve cell adhesion, and recent advances in their synthesis include methods for modifying the ligand density and distribution onto nanoparticles surface. However, this work reports the development of biodegradable polymeric nanoparticles capable of promoting cellular adhesion without any surface chemical modification by ligands. Biocompatible and biodegradable nanoparticles based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) were synthesized by solvent evaporation method. The produced nanoparticles were small in size (85 and 125 nm) and colloidally stable against time in aqueous solution. Morphology evaluation showed their spherical shape with small polydispersity. Human osteoblast-like cells (MG63) were cultured in the presence of PHBHV nanoparticles, and growth kinetics were compared to those grown on tissue culture polystyrene (TCPS). Cell attachment on non-tissue culture polystyrene (non-TCPS) pre-coated with nanoparticles was assessed and compared to attachment on TCPS. These findings reveal the potential of PHBHV nanoparticles for cell adhesion and growth, without requiring a matrix ligand to support cells, to be used as scaffolds, in tissue engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title="tissue engineering">tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=PHBHV" title=" PHBHV"> PHBHV</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells"> stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=cellular%20attachment" title=" cellular attachment"> cellular attachment</a> </p> <a href="https://publications.waset.org/abstracts/81789/engineering-ligand-free-biodegradable-based-nanoparticles-for-cell-attachment-and-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81789.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">210</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> A Study on the Impact of Covid-19 on Primary Healthcare Workers in Ekiti State, South-West Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adeyinka%20Adeniran">Adeyinka Adeniran</a>, <a href="https://publications.waset.org/abstracts/search?q=Omowunmi%20Bakare"> Omowunmi Bakare</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Oluwole"> Esther Oluwole</a>, <a href="https://publications.waset.org/abstracts/search?q=Florence%20Chieme"> Florence Chieme</a>, <a href="https://publications.waset.org/abstracts/search?q=Temitope%20Durojaiye"> Temitope Durojaiye</a>, <a href="https://publications.waset.org/abstracts/search?q=Modupe%20Akinyinka"> Modupe Akinyinka</a>, <a href="https://publications.waset.org/abstracts/search?q=Omobola%20Ojo"> Omobola Ojo</a>, <a href="https://publications.waset.org/abstracts/search?q=Babatunde%20Olujobi"> Babatunde Olujobi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Ilesanmi"> Marcus Ilesanmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Akintunde%20Ogunsakin"> Akintunde Ogunsakin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Globally, COVID-19 has greatly impacted the human race physically, socially, mentally, and economically.

Methods: The study was a cross-sectional descriptive study using a quantitative data collection method of 716 primary healthcare workers in Ekiti state. Respondents were selected using an online convenience sampling method via their social media platforms. Data was collected, collated, and analyzed using SPSS version 25 software and presented as frequency tables, mean and standard deviation. Bivariate and multivariate analyses were conducted using a t-test, and the level of statistical significance was set at p<0.05. Results: Less than half (47.1%) of respondents were between 41-50 age group and a mean age of 44.4+6.4SD. A majority (89.4%) were female, and almost all (96.2%) were married. More than (90%) had ever heard of Coronavirus, and (85.8%) had to spend more money on activities of daily living such as transportation (90.1%), groceries (80.6%), assisting relations (95.8%) and sanitary measures (disinfection) at home (95.0%). COVID-19 had a huge negative impact on about (89.7%) of healthcare workers, with a mean score of 22+4.8. Conclusion: COVID-19 negatively impacted the daily living and professional duties of primary healthcare workers, which reflected their psychological, physical, social, and economic well-being. Disease outbreaks are unlikely to disappear in the near future. Hence, global proactive interventions and homegrown measures should be adopted to protect healthcare workers and save lives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title="Covid-19">Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20workforce" title=" health workforce"> health workforce</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20health%20care" title=" primary health care"> primary health care</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20systems" title=" health systems"> health systems</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a> </p> <a href="https://publications.waset.org/abstracts/161276/a-study-on-the-impact-of-covid-19-on-primary-healthcare-workers-in-ekiti-state-south-west-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161276.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">84</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> The Effectiveness of Cash Flow Management by SMEs in the Mafikeng Local Municipality of South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ateba%20Benedict%20Belobo">Ateba Benedict Belobo</a>, <a href="https://publications.waset.org/abstracts/search?q=Faan%20Pelser"> Faan Pelser</a>, <a href="https://publications.waset.org/abstracts/search?q=Ambe%20Marcus"> Ambe Marcus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aims: This study arise from repeated complaints from both electronic mails about the underperformance of Mafikeng Small and Medium-Size enterprises after the global financial crisis. The authors were on the view that, this poor performance experienced could be as a result of the negative effects on the cash flow of these businesses due to volatilities in the business environment in general prior to the global crisis. Thus, the paper was mainly aimed at determining the shortcomings experienced by these SMEs with regards to cash flow management. It was also aimed at suggesting possible measures to improve cash flow management of these SMEs in this tough time. Methods: A case study was conducted on 3 beverage suppliers, 27 bottle stores, 3 largest fast consumer goods super markets and 7 automobiles enterprises in the Mafikeng local municipality. A mixed method research design was employed and a purposive sampling was used in selecting SMEs that participated. Views and experiences of participants of the paper were captured through in-depth interviews. Data from the empirical investigation were interpreted using open coding and a simple percentage formula. Results: Findings from the empirical research reflected that majority of Mafikeng SMEs suffer poor operational performance prior to the global financial crisis primarily as a result of poor cash flow management. However, the empirical outcome also indicted other secondary factors contributing to this poor operational performance. Conclusion: Finally, the authorsproposed possible measures that could be used to improve cash flow management and to solve other factors affecting operational performance of SMEs in the Mafikeng local municipality in other to achieve a better business performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cash%20flow" title="cash flow">cash flow</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20performance" title=" business performance"> business performance</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20financial%20crisis" title=" global financial crisis"> global financial crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a> </p> <a href="https://publications.waset.org/abstracts/23084/the-effectiveness-of-cash-flow-management-by-smes-in-the-mafikeng-local-municipality-of-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23084.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">439</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> The Media and Reportage of Boko Haram Insurgency in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priscilla%20Marcus">Priscilla Marcus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mass media was a force to reckon with in the struggle and attainment of Nigeria’s independence in 1960 and since then, the Nigerian media has carved a niche for itself in performing its traditional role of education, information, entertainment, shaping of opinions and swinging of views of the society on knotty national issues. Boko Haram insurgency in Nigeria which emerged from an unnoticed, negligible and quiet beginning, has turned out daring, monstrous and unstoppable. This paper examines The Media and Reportage of Boko Haram Insurgency in Nigeria and to suggest strategies the mass media could adopt in combating this form of terrorism. Data for the study were collected from a variety of sources including the print and electronic media. The major observation of this study is that the mass media have an enormous role to play if Boko Haram’s activities are to be combated. It argued that even though the media houses are just doing their job – reporting the incident(s) as they occur, thus keeping the citizens abreast of facts; the rate at which news keeps coming regarding the activities of the sect has portrayed the media as information dissemination and terror campaign spread. It also argued that the ceaseless reporting has not translated to a decrease in the activities of the sect or increase in the level of government actions to check the insurgency. However, the information being disseminated is enlightening the populace and also creating an atmosphere of panic and insecurity. It further argued that the media should move beyond mere recitation of events to providing the public with knowledge needed to make things better. This is because the sect has been accorded too much undeserved and unnecessary publicity while the government on the other hand has been portrayed, albeit indirectly as a weak organization incapable of handling the ‘more organized’ Boko Haram. The study, concluded that, to effectively address the problem of this form of terrorism in Nigeria, the media have to brace up to the task of uncovering activities of the sect in appreciation of their watch-dog role. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boko%20Haram" title="Boko Haram">Boko Haram</a>, <a href="https://publications.waset.org/abstracts/search?q=insurgency" title=" insurgency"> insurgency</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20media" title=" mass media"> mass media</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/53533/the-media-and-reportage-of-boko-haram-insurgency-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53533.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">326</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> Linearly Polarized Single Photon Emission from Nonpolar, Semipolar and Polar Quantum Dots in GaN/InGaN Nanowires </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Snezana%20Lazic">Snezana Lazic</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarko%20Gacevic"> Zarko Gacevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Holmes"> Mark Holmes</a>, <a href="https://publications.waset.org/abstracts/search?q=Ekaterina%20Chernysheva"> Ekaterina Chernysheva</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20M%C3%BCller"> Marcus Müller</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Veit"> Peter Veit</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Bertram"> Frank Bertram</a>, <a href="https://publications.waset.org/abstracts/search?q=Juergen%20Christen"> Juergen Christen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasuhiko%20Arakawa"> Yasuhiko Arakawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Calleja"> Enrique Calleja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study reports how the pencil-like morphology of a homoepitaxially grown GaN nanowire can be exploited for the fabrication of a thin conformal InGaN nanoshell, hosting nonpolar, semipolar and polar single photon sources (SPSs). All three SPS types exhibit narrow emission lines (FWHM~0.35 - 2 meV) and high degrees of linear optical polarization (P > 70%) in the low-temperature micro-photoluminescence (µ-PL) experiments and are characterized by a pronounced antibunching in the photon correlation measurements (gcorrected(2)(0) < 0.3). The quantum-dot-like exciton localization centers induced by compositional fluctuations within the InGaN nanoshell are identified as the driving mechanism for the single photon emission. As confirmed by the low-temperature transmission electron microscopy combined with cathodoluminescence (TEM-CL) study, the crystal region (i.e. non-polar m-, semi-polar r- and polar c-facets) hosting the single photon emitters strongly affects their emission wavelength, which ranges from ultra-violet for the non-polar to visible for the polar SPSs. The photon emission lifetime is also found to be facet-dependent and varies from sub-nanosecond time scales for the non- and semi-polar SPSs to a few nanoseconds for the polar ones. These differences are mainly attributed to facet-dependent indium content and electric field distribution across the hosting InGaN nanoshell. The hereby reported pencil-like InGaN nanoshell is the first single nanostructure able to host all three types of single photon emitters and is thus a promising building block for tunable quantum light devices integrated into future photonic and optoelectronic circuits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GaN%20nanowire"
