inflammation are key causes of transplant malfunctioning and permanent failure, which play a major role in the development of chronic rejection of the transplanted organ. Inflammation-induced microvascular loss is a promising area to investigate the decisive roles of regulatory and effector responses. The present study was designed to investigate the impact of IL-10 on immunotolerance, in particular, the microenvironment of the allograft during rejection. Here, we investigated the effects of IL-10 blockade/ reconstitution and serially monitored regulatory T cells (Tregs), graft microvasculature, and airway epithelium in rejecting airway transplants. We demonstrated that the blocking/reconstitution of IL-10 significantly modulates CD4+FOXP3+ Tregs, microvasculature, and airway epithelium during rejection. Our findings further highlighted that blockade of IL-10 upregulated proinflammatory cytokines, IL-2, IL-1β, IFN-γ, IL-15, and IL-23, but suppressed IL-5 secretion during rejection; however, reconstitution of IL-10 significantly upregulated CD4+FOXP3+ Tregs, tissue oxygenation/blood flow and airway repair. Collectively, these findings demonstrate a potential reparative modulation of IL-10 during microvascular and epithelial repair, which could provide a vital therapeutic window to rejecting transplants in clinical practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interleukin%20-10" title="interleukin -10">interleukin -10</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory%20T%20cells" title=" regulatory T cells"> regulatory T cells</a>, <a href="https://publications.waset.org/abstracts/search?q=allograft%20rejection" title=" allograft rejection"> allograft rejection</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotolerance" title=" immunotolerance"> immunotolerance</a> </p> <a href="https://publications.waset.org/abstracts/114156/immunomodulation-by-interleukin-10-therapy-in-mouse-airway-transplantation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114156.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">175</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> iPSC-derived MSC Mediated Immunosuppression during Mouse Airway Transplantation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Afzal%20Khan">Mohammad Afzal Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatimah%20Alanazi"> Fatimah Alanazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hala%20Abdalrahman%20Ahmed"> Hala Abdalrahman Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Talal%20Shamma"> Talal Shamma</a>, <a href="https://publications.waset.org/abstracts/search?q=Kilian%20Kelly"> Kilian Kelly</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20A.%20Hammad"> Mohammed A.

Despite the remarkable short-term recovery, long-term lung survival continues to face several significant challenges, including chronic rejection and severe toxic side-effects due to global immunosuppression. Stem cell-based immunotherapy has been recognized as a crucial immunoregulatory regimen in various preclinical and clinical studies. Despite initial therapeutic outcomes, conventional stem cells face key limitations. The Cymerus™ manufacturing facilitates the production of a virtually limitless supply of consistent human induced pluripotent stem cell (iPSC)-derived mesenchymal stem cells, which could play a key role in selective immunosuppression and graft repair during rejection. Here, we demonstrated the impact of iPSC-derived human MSCs on the development of immune-tolerance and long-term graft survival in mouse orthotopic airway allografts. BALB/c→C57BL/6 allografts were reconstituted with iPSC-derived MSCs (2 million/transplant/ at d0), and allografts were examined for regulatory T cells (Tregs), oxygenation, microvascular blood flow, airway epithelium and collagen deposition during rejection. We demonstrated that iPSC-derived MSC treatment leads to significant increase in tissue expression of hTSG-6 protein, followed by an upregulation of mouse Tregs and IL-5, IL-10, IL-15 cytokines, which augments graft microvascular blood flow and oxygenation, and thereby maintained a healthy airway epithelium and prevented the subepithelial deposition of collagen at d90 post-transplantation. Collectively, these data confirmed that iPSC-derived MSC-mediated immunosuppression has potential to establish immune-tolerance and rescue allograft from sustained hypoxic/ischemic phase and subsequently limits long-term airway epithelial injury and collagen progression, which therapeutically warrant a study of Cymerus iPSC-derived MSCs as a potential management option for immunosuppression in transplant recipients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stem%20cell%20therapy" title="stem cell therapy">stem cell therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotolerance" title=" immunotolerance"> immunotolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory%20T%20cells" title=" regulatory T cells"> regulatory T cells</a>, <a href="https://publications.waset.org/abstracts/search?q=hypoxia%20and%20ischemia" title=" hypoxia and ischemia"> hypoxia and ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=microvasculature" title=" microvasculature"> microvasculature</a> </p> <a href="https://publications.waset.org/abstracts/114237/ipsc-derived-msc-mediated-immunosuppression-during-mouse-airway-transplantation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114237.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">158</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> The Language of Landscape Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hosna%20Pourhashemi">Hosna Pourhashemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chahar Bagh, the symbol of the world, displayed around the pool of life in the centre, attempts to emulate Eden. It represents a duality concept based on the division of the universe into two perceptional insights, a celestial and an earthly one. Chahar Bagh garden pattern refers to the Garden of Eden, that was watered and framed by main four rivers. This microcosm is combined with a mystical love of flowers, sweet-scented trees, the variety of colors, and the sense of eternal life. This symbol of the integration of spontaneous expressivity of the natural elements and reasoning awareness of man strives for the ideal of divine perfection. Through collecting and analyzing the data, the prevalence and continuous influence of Chahar Bagh concept on selected historical gardens was elaborated and evaluated. After the conquest of Persia by the Arabs in the 7th century, Chahar Bagh was adopted and spread throughout the Islamic expansion, from the Middle East, westward across northern Africa to Morocco and the Iberian Peninsula, and eastward through Iran to Central Asia and India. Furthermore, its continuity to the mid of 16th century Renaissance period is shown. By adapting the semiotic theory of Peirce and Saussure on the Persian garden, Chahar Bagh was defined as the basic pattern language for the garden culture. The hypothesis of the continuous influence of Chahar Bagh pattern language on today’s landscape architecture was examined on selected works of Dieter Kienast, as the important and relevant protagonist of his time (end of twentieth ct.) and up to our time. Chahar Bagh pattern language offers collective cultural sensitive healing wisdom transmitted down through the millennia. Through my reflections in Dieter Kienast’s works, I transformed my personal experience into a transpersonal understanding regarding the Sufi philosophy and the Jung psychology, which brings me to define new design theories and methods to form a spiritual, as I call it” Quaternary Perception Model” for landscape architecture. Based on a cognition process through self-journeying in this holistic model, human consciousness can be developed to access to “higher” levels of being and embrace the unity. The self-purification and mindfulness through transpersonal confrontation in the ”Quaternary Perception Model” generates a form of heart-based treatment. I adapted the seven spiritual levels of Sufi self-development on the perception of landscape, representing the stages of the self, ranging from absolutely self-centered to pure spiritual humanity. I redefine and reread the elements and features of Chahar Bagh pattern language for today’s landscape architecture. The “lost paradise” lies in our heart and can be perceived by all humans in landscapes and cities designed in the spirit of” Quaternary Model”. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=persian%20garden" title="persian garden">persian garden</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20language%20of%20Chahar%20Bagh" title=" pattern language of Chahar Bagh"> pattern language of Chahar Bagh</a>, <a href="https://publications.waset.org/abstracts/search?q=wholistic%20Perception" title=" wholistic Perception"> wholistic Perception</a>, <a href="https://publications.waset.org/abstracts/search?q=dieter%20kienast" title=" dieter kienast"> dieter kienast</a>, <a href="https://publications.waset.org/abstracts/search?q=%E2%80%9Cquaternary%20model%E2%80%9D" title=" “quaternary model”"> “quaternary model”</a> </p> <a href="https://publications.waset.org/abstracts/159230/the-language-of-landscape-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159230.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">19</span> Solving Extended Linear Complementarity Problems (XLCP) - Wood and Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liberto%20Pombal">Liberto Pombal</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Dieter%20Jaekel"> Christian Dieter Jaekel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work is to establish theoretical and numerical conditions for Solving Extended Linear Complementarity Problems (XLCP), with emphasis on the Horizontal Linear Complementarity Problem (HLCP).

To achieve a better package quality and a stable transfer molding process, it is necessary to understand the influence of the process parameters on the package quality. This work aims to comprehend the relationship between the process parameters, and to identify the optimum process parameters for the transfer molding process in order to achieve less voids and wire sweep. To achieve this, a DoE is executed for process optimization and a regression analysis is carried out. A systematic approach is represented to generate models which enable an estimation of the number of voids and wire sweep.

We use a quadric error metric to calculate an error value for each vertex of the mesh and order all vertices based on this value. This step is followed by the parallel removal of a number of vertices with the lowest calculated error values. To allow for the parallel removal of multiple vertices we use a set of per-vertex boundaries that prevent mesh foldovers even when simplification operations are performed on neighbouring vertices. We execute multiple iterations of the calculation of the vertex errors, ordering of the error values and removal of vertices until either a desired number of vertices remains in the mesh or a minimum error value is reached. This parallel approach is used to speed up the simplification process while maintaining mesh topology and avoiding foldovers at every step of the simplification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20graphics" title="computer graphics">computer graphics</a>, <a href="https://publications.waset.org/abstracts/search?q=half%20edge%20collapse" title=" half edge collapse"> half edge collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20simplification" title=" mesh simplification"> mesh simplification</a>, <a href="https://publications.waset.org/abstracts/search?q=precomputed%20simplification" title=" precomputed simplification"> precomputed simplification</a>, <a href="https://publications.waset.org/abstracts/search?q=topology%20preserving" title=" topology preserving"> topology preserving</a> </p> <a href="https://publications.waset.org/abstracts/36600/gpu-accelerated-triangle-mesh-simplification-using-parallel-vertex-removal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36600.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">367</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> Enhancing Rural Agricultural Value Chains through Electric Mobility Services in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clemens%20Pizzinini">Clemens Pizzinini</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Rosner"> Philipp Rosner</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Ziegler"> David Ziegler</a>, <a href="https://publications.waset.org/abstracts/search?q=Markus%20Lienkamp"> Markus Lienkamp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transportation is a constitutional part of most supply and value chains in modern economies.

The state-space equations of EKF are established based on the electrical, mechanical and the simplified thermal models of an asynchronous machine. The asynchronous machine with simplified thermal model in Dymola is compiled as DymolaBlock, a physical model in MATLAB/Simulink. The coolant air temperature, three-phase voltages and currents are exported from the physical model and are processed by EKF estimator as inputs. Compared to the temperatures exported from the physical model of the machine, three parts of temperatures can be estimated quite accurately by the EKF estimator. The online EKF estimator is independent from the machine control algorithm and can work under any speed and load condition if the stator current is nonzero current system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asynchronous%20machine" title="asynchronous machine">asynchronous machine</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20Kalman%20filter" title=" extended Kalman filter"> extended Kalman filter</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20estimation" title=" temperature estimation"> temperature estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20model" title=" thermal model"> thermal model</a> </p> <a href="https://publications.waset.org/abstracts/67431/estimation-of-the-temperatures-in-an-asynchronous-machine-using-extended-kalman-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67431.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">285</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">14</span> Modeling and Analysis of a Cycling Prosthetic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Tolentino">John Tolentino</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Seok%20Park"> Yong Seok Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are currently many people living with limb loss in the USA. The main causes for amputation can range from vascular disease, to trauma, or cancer. This number is expected increase over the next decade. Many patients have a single prosthetic for the first year but end up getting a second one to accommodate their changing physique. Afterwards, the prosthesis gets replaced every three to five years depending on how often it is used. This could cost the patient up to $500,000 throughout their lifetime. Complications do not end there, however. Due to the absence of nerves, it becomes more difficult to traverse terrain with a prosthetic. Moving on an incline or decline becomes difficult, thus curbs and stairs can be a challenge. Certain physical activities, such as cycling, could be even more strenuous. It will need to be relearned to accommodate for the change in weight, center of gravity, and transfer of energy from the leg to the pedal. The purpose of this research project is to develop a new, alternate below-knee cycling prosthetic using Dieter & Schmidt’s design process approach. It will be subjected to fatigue analysis under dynamic loading to observe the limitations as well as the strengths and weaknesses of the prosthetic. Benchmark comparisons will be made between existing prosthetics and the proposed one, examining the benefits and disadvantages. The resulting prosthetic will be 3D printed using acrylonitrile butadiene styrene (ABS) or polycarbonate (PC) plastic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20Printing" title="3D Printing">3D Printing</a>, <a href="https://publications.waset.org/abstracts/search?q=Cycling" title=" Cycling"> Cycling</a>, <a href="https://publications.waset.org/abstracts/search?q=Prosthetic%20design" title=" Prosthetic design"> Prosthetic design</a>, <a href="https://publications.waset.org/abstracts/search?q=Synthetic%20design." title=" Synthetic design."> Synthetic design.</a> </p> <a href="https://publications.waset.org/abstracts/123679/modeling-and-analysis-of-a-cycling-prosthetic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123679.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">142</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">13</span> Software Engineering Inspired Cost Estimation for Process Modelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felix%20Baumann">Felix Baumann</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksandar%20Milutinovic"> Aleksandar Milutinovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Dieter%20Roller"> Dieter Roller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Up to this point business process management projects in general and business process modelling projects in particular could not rely on a practical and scientifically validated method to estimate cost and effort. Especially the model development phase is not covered by a cost estimation method or model. Further phases of business process modelling starting with implementation are covered by initial solutions which are discussed in the literature. This article proposes a method of filling this gap by deriving a cost estimation method from available methods in similar domains namely software development or software engineering. Software development is regarded as closely similar to process modelling as we show. After the proposition of this method different ideas for further analysis and validation of the method are proposed. We derive this method from COCOMO II and Function Point which are established methods of effort estimation in the domain of software development. For this we lay out similarities of the software development rocess and the process of process modelling which is a phase of the Business Process Management life-cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COCOMO%20II" title="COCOMO II">COCOMO II</a>, <a href="https://publications.waset.org/abstracts/search?q=busines%20process%20modeling" title=" busines process modeling"> busines process modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20estimation%20method" title=" cost estimation method"> cost estimation method</a>, <a href="https://publications.waset.org/abstracts/search?q=BPM%20COCOMO" title=" BPM COCOMO"> BPM COCOMO</a> </p> <a href="https://publications.waset.org/abstracts/41029/software-engineering-inspired-cost-estimation-for-process-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41029.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">440</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">12</span> Smart-Textile Containers for Urban Mobility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ren%C3%A9%20Vieroth">René Vieroth</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Dils"> Christian Dils</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20V.%20Krshiwoblozki"> M.

Bicycle based solutions are already and since a long time the key to success. Modern developments like e-bikes and high-end cargo-bikes complement the portfolio. Weight, aerodynamic drag, and security for the transported goods are the key factors for working solutions. Recent achievements in the field of smart-textiles allowed the creation of a totally new generation of intelligent textile cargo containers, which fulfill those demands. The fusion of technical textiles, design and electrical engineering made it possible to create an ecological solution which is very near to become a product. This paper shows all the details of this solution that includes an especially developed sensor textile for cut detection, a protective textile layer for intrusion prevention, an universal-charging-unit for energy harvesting from diverse sources and a low-energy alarm system with GSM/GPRS connection, GPS location and RFID interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cargo-bike" title="cargo-bike">cargo-bike</a>, <a href="https://publications.waset.org/abstracts/search?q=cut-detection" title=" cut-detection"> cut-detection</a>, <a href="https://publications.waset.org/abstracts/search?q=e-bike" title=" e-bike"> e-bike</a>, <a href="https://publications.waset.org/abstracts/search?q=energy-harvesting" title=" energy-harvesting"> energy-harvesting</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20urban%20mobility" title=" green urban mobility"> green urban mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics" title=" logistics"> logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=smart-textiles" title=" smart-textiles"> smart-textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=textile-integrity%20sensor" title=" textile-integrity sensor"> textile-integrity sensor</a> </p> <a href="https://publications.waset.org/abstracts/77783/smart-textile-containers-for-urban-mobility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77783.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">315</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">11</span> Disrupted or Discounted Cash Flow: Impact of Digitisation on Business Valuation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthias%20Haerri">Matthias Haerri</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Huettche"> Tobias Huettche</a>, <a href="https://publications.waset.org/abstracts/search?q=Clemens%20Kustner"> Clemens Kustner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article discusses the impact of digitization on business valuation. In order to become and remain ‘digital’, investments are necessary whose return on investment (ROI) often remains vague. This uncertainty is contradictory for a valuation, that rely on predictable cash flows, fixed capital structures and the steady state. However digitisation does not make a company valuation impossible, but traditional approaches must be reconsidered. The authors identify four areas that are to be changing: (1) Tools instead of intuition - In the future, company valuation will neither be art nor science, but craft. This does not require intuition, but experience and good tools. Digital evaluation tools beyond Excel will therefore gain in importance. (2) Real-time instead of deadline - At present, company valuations are always carried out on a case-by-case basis and on a specific key date. This will change with the digitalization and the introduction of web-based valuation tools. Company valuations can thus not only be carried out faster and more efficiently, but can also be offered more frequently. Instead of calculating the value for a previous key date, current and real-time valuations can be carried out. (3) Predictive planning instead of analysis of the past - Past data will also be needed in the future, but its use will not be limited to monovalent time series or key figure analyses. With pictures of ‘black swans’ and the ‘turkey illusion’ it was made clear to us that we build forecasts on too few data points of the past and underestimate the power of chance. Predictive planning can help here. (4) Convergence instead of residual value - Digital transformation shortens the lifespan of viable business models. If companies want to live forever, they have to change forever. For the company valuation, this means that the business model valid on the valuation date only has a limited service life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20valuation" title="business valuation">business valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20finance" title=" corporate finance"> corporate finance</a>, <a href="https://publications.waset.org/abstracts/search?q=digitisation" title=" digitisation"> digitisation</a>, <a href="https://publications.waset.org/abstracts/search?q=disruption" title=" disruption"> disruption</a> </p> <a href="https://publications.waset.org/abstracts/105970/disrupted-or-discounted-cash-flow-impact-of-digitisation-on-business-valuation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105970.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">133</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">10</span> Violence against Police Officers in Germany</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anne%20T.%20Herr">Anne T. Herr</a>, <a href="https://publications.waset.org/abstracts/search?q=Clemens%20Lorei"> Clemens Lorei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Employees of organizations with security tasks, such as emergency services, public order services, or police forces, work every day to ensure people's safety. Violence against police is, therefore, a relevant topic both socially and politically. An increase in violence is often discussed without there being any verifiable and generally valid data. So far, scientific research has mainly focused on offender characteristics and crime statistics. These surveys are mostly subjective, retrospective, and neglect the dynamics and interactions in concrete violent situations. Therefore, more recent research methods attempt to capture the issue of violence against emergency forces more comprehensively. However, the operationalization of the constructs and the methodological approach pose particular challenges. This contribution provides an overview of new perspectives on the understanding of violent assaults and identifies current research gaps. In addition, a new research project of the Hessian University of Police and Administration in Germany is presented. In the 'AMBOSafe' study, different theoretical backgrounds for understanding violence against police and emergency services personnel will be combined in order to capture as many different perspectives of violent assaults as possible in a multimodal research approach. In a retrospective as well as in a longitudinal survey, the conditions of escalation dynamics in the assaults are recorded and supplemented by the current and valid prevalence of physical and verbal assaults in a period of four months. In addition, qualitative interviews with those affected will be used to record more detailed descriptions of and the feelings during the assaults, as well as possible causes and connections between the different groups of people. In addition to the reports of the police forces, the motives of the attackers will be collected and supplemented by analyzing the criminal case files. This knowledge can contribute to a more comprehensive understanding of violent assaults against police forces in order to be able to derive scientifically based preventive measures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assaults" title="assaults">assaults</a>, <a href="https://publications.waset.org/abstracts/search?q=crime%20statistics" title=" crime statistics"> crime statistics</a>, <a href="https://publications.waset.org/abstracts/search?q=escalation%20dynamics" title=" escalation dynamics"> escalation dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=police" title=" police"> police</a> </p> <a href="https://publications.waset.org/abstracts/134902/violence-against-police-officers-in-germany" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134902.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">114</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">9</span> Exploring the Relationship between Organisational Identity and Value Systems: Reflecting on the Values-Crafting Process in a Multi-National Organisation within the Entertainment Industry </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dieter%20Veldsman">Dieter Veldsman</a>, <a href="https://publications.waset.org/abstracts/search?q=Theo%20Heyns%20Veldsman"> Theo Heyns Veldsman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The knowledge economy demands an organisation that is flexible, adaptable and able to navigate the ever-changing environment. This fast-paced environment has however resulted in an organizational landscape that battles to engage employees, retain top talent and create meaningful work for its members. In the knowledge economy, the concept of organizational identity has become an important consideration as organisations aim to create a compelling and inviting narrative for all stakeholders across the business value chain. Values are often seen as the behavioural framework that informs organisational culture, yet often values are perceived to be inauthentic and misaligned with the true character or identity of the organisation and how it is perceived by different role players. This paper focuses on exploring the relationship between organisational identity and value systems by focusing on a case study within a multi-national organisation within South Africa. The paper evaluates the implementation of mixed methods OD approach that gathered collaborative inputs of more than 4500 employees who participated in crafting the newly established values system post a retrenchment process. The paper will evaluate the relationship between the newly crafted value system and the identity of the organisation as described by various internal and external stakeholders in order to explore potential alignment, dissonance and key insights into understanding the relationship between organisational identity and values. The case study will be reported from the perspective of an OD consultant who supported the transformation process over a period of 8 months and aims to provide key insights into values and identity alignment within knowledge economy organisations. From a practical perspective, the paper provides insights into how values are created, perceived and lived within organisations and the impact on employee engagement and culture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=culture" title="culture">culture</a>, <a href="https://publications.waset.org/abstracts/search?q=organisational%20development" title=" organisational development"> organisational development</a>, <a href="https://publications.waset.org/abstracts/search?q=organisational%20identity" title=" organisational identity"> organisational identity</a>, <a href="https://publications.waset.org/abstracts/search?q=values" title=" values"> values</a> </p> <a href="https://publications.waset.org/abstracts/59224/exploring-the-relationship-between-organisational-identity-and-value-systems-reflecting-on-the-values-crafting-process-in-a-multi-national-organisation-within-the-entertainment-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59224.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">310</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">8</span> A Non-Invasive Neonatal Jaundice Screening Device Measuring Bilirubin on Eyes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Shihao">Li Shihao</a>, <a href="https://publications.waset.org/abstracts/search?q=Dieter%20Trau"> Dieter Trau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bilirubin is a yellow substance that is made when the body breaks down old red blood cells. High levels of bilirubin can cause jaundice, a condition that makes the newborn's skin and the white part of the eyes look yellow. Jaundice is a serial-killer in developing countries in Southeast Asia such as Myanmar and most parts of Africa where jaundice screening is largely unavailable. Worldwide, 60% of newborns experience infant jaundice. One in ten will require therapy to prevent serious complications and lifelong neurologic sequelae. Limitations of current solutions: - Blood test: Blood tests are painful may largely unavailable in poor areas of developing countries, and also can be costly and unsafe due to the insufficient investment and lack of access to health care systems. - Transcutaneous jaundice-meter: 1) can only provide reliable results to caucasian newborns, due to skin pigmentations since current technologies measure bilirubin by the color of the skin. Basically, the darker the skin is, the harder to measure, 2) current jaundice meters are not affordable for most underdeveloped areas in Africa like Kenya and Togo, 3) fat tissue under the skin also influences the accuracy, which will give overestimated results, 4) current jaundice meters are not reliable after treatment (phototherapy) because bilirubin levels underneath the skin will be reduced first, while overall levels may be quite high. Thus, there is an urgent need for a low-cost non-invasive device, which can be effective not only for caucasian babies but also Asian and African newborns, to save lives at the most vulnerable time and prevent any complications like brain damage. Instead of measuring bilirubin on skin, we proposed a new method to do the measurement on the sclera, which can avoid the difference of skin pigmentations and ethnicities, due to the necessity for the sclera to be white regardless of racial background. This is a novel approach for measuring bilirubin by an optical method of light reflection off the white part of the eye. Moreover, the device is connected to a smart device, which can provide a user-friendly interface and the ability to record the clinical data continuously A disposable eye cap will be provided avoiding contamination and fixing the distance to the eye. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaundice" title="Jaundice">Jaundice</a>, <a href="https://publications.waset.org/abstracts/search?q=bilirubin" title=" bilirubin"> bilirubin</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive" title=" non-invasive"> non-invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=sclera" title=" sclera"> sclera</a> </p> <a href="https://publications.waset.org/abstracts/50345/a-non-invasive-neonatal-jaundice-screening-device-measuring-bilirubin-on-eyes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50345.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">236</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">7</span> Doing Durable Organisational Identity Work in the Transforming World of Work: Meeting the Challenge of Different Workplace Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theo%20Heyns%20Veldsman">Theo Heyns Veldsman</a>, <a href="https://publications.waset.org/abstracts/search?q=Dieter%20Veldsman"> Dieter Veldsman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organisational Identity (OI) refers to who and what the organisation is, what it stands for and does, and what it aspires to become. OI explores the perspectives of how we see ourselves, are seen by others and aspire to be seen. It provides as rationale the ‘why’ for the organisation’s continued existence. The most widely accepted differentiating features of OI are encapsulated in the organisation’s core, distinctive, differentiating, and enduring attributes. OI finds its concrete expression in the organisation’s Purpose, Vision, Strategy, Core Ideology, and Legacy. In the emerging new order infused by hyper-turbulence and hyper-fluidity, the VICCAS world, OI provides a secure anchor and steady reference point for the organisation, particularly the growing widespread focus on Purpose, which is indicative of the organisation’s sense of social citizenship. However, the transforming world of work (TWOW) - particularly the potent mix of ongoing disruptive innovation, the 4th Industrial Revolution, and the gig economy with the totally unpredicted COVID19 pandemic - has resulted in the consequential adoption of different workplace strategies by organisations in terms of how, where, and when work takes place. Different employment relations (transient to permanent); work locations (on-site to remote); work time arrangements (full-time at work to flexible work schedules); and technology enablement (face-to-face to virtual) now form the basis of the employer/employee relationship. The different workplace strategies, fueled by the demands of TWOW, pose a substantive challenge to organisations of doing durable OI work, able to fulfill OI’s critical attributes of core, distinctive, differentiating, and enduring. OI work is contained in the ongoing, reciprocally interdependent stages of sense-breaking, sense-giving, internalisation, enactment, and affirmation. The objective of our paper is to explore how to do durable OI work relative to different workplace strategies in the TWOW. Using a conceptual-theoretical approach from a practice-based orientation, the paper addresses the following topics: distinguishes different workplace strategies based upon a time/place continuum; explicates stage-wise the differential organisational content and process consequences of these strategies for durable OI work; indicates the critical success factors of durable OI work under these differential conditions; recommends guidelines for OI work relative to TWOW; and points out ethical implications of all of the above. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organisational%20identity" title="organisational identity">organisational identity</a>, <a href="https://publications.waset.org/abstracts/search?q=workplace%20strategies" title=" workplace strategies"> workplace strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20world%20of%20work" title=" new world of work"> new world of work</a>, <a href="https://publications.waset.org/abstracts/search?q=durable%20organisational%20identity%20work" title=" durable organisational identity work"> durable organisational identity work</a> </p> <a href="https://publications.waset.org/abstracts/151531/doing-durable-organisational-identity-work-in-the-transforming-world-of-work-meeting-the-challenge-of-different-workplace-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151531.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">200</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">6</span> Variable Renewable Energy Droughts in the Power Sector – A Model-based Analysis and Implications in the European Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Kittel">Martin Kittel</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Roth"> Alexander Roth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The continuous integration of variable renewable energy sources (VRE) in the power sector is required for decarbonizing the European economy. Power sectors become increasingly exposed to weather variability, as the availability of VRE, i.e., mainly wind and solar photovoltaic, is not persistent. Extreme events, e.g., long-lasting periods of scarce VRE availability (‘VRE droughts’), challenge the reliability of supply. Properly accounting for the severity of VRE droughts is crucial for designing a resilient renewable European power sector. Energy system modeling is used to identify such a design. Our analysis reveals the sensitivity of the optimal design of the European power sector towards VRE droughts. We analyze how VRE droughts impact optimal power sector investments, especially in generation and flexibility capacity. We draw upon work that systematically identifies VRE drought patterns in Europe in terms of frequency, duration, and seasonality, as well as the cross-regional and cross-technological correlation of most extreme drought periods. Based on their analysis, the authors provide a selection of relevant historical weather years representing different grades of VRE drought severity. These weather years will serve as input for the capacity expansion model for the European power sector used in this analysis (DIETER). We additionally conduct robustness checks varying policy-relevant assumptions on capacity expansion limits, interconnections, and level of sector coupling. Preliminary results illustrate how an imprudent selection of weather years may cause underestimating the severity of VRE droughts, flawing modeling insights concerning the need for flexibility. Sub-optimal European power sector designs vulnerable to extreme weather can result. Using relevant weather years that appropriately represent extreme weather events, our analysis identifies a resilient design of the European power sector. Although the scope of this work is limited to the European power sector, we are confident that our insights apply to other regions of the world with similar weather patterns. Many energy system studies still rely on one or a limited number of sometimes arbitrarily chosen weather years. We argue that the deliberate selection of relevant weather years is imperative for robust modeling results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20systems" title="energy systems">energy systems</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20optimization" title=" numerical optimization"> numerical optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20renewable%20energy%20sources" title=" variable renewable energy sources"> variable renewable energy sources</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20drought" title=" energy drought"> energy drought</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility" title=" flexibility"> flexibility</a> </p> <a href="https://publications.waset.org/abstracts/162542/variable-renewable-energy-droughts-in-the-power-sector-a-model-based-analysis-and-implications-in-the-european-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162542.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">72</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">5</span> Selective Extraction of Lithium from Native Geothermal Brines Using Lithium-ion Sieves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Misagh%20Ghobadi">Misagh Ghobadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rich%20Crane"> Rich Crane</a>, <a href="https://publications.waset.org/abstracts/search?q=Karen%20Hudson-Edwards"> Karen Hudson-Edwards</a>, <a href="https://publications.waset.org/abstracts/search?q=Clemens%20Vinzenz%20Ullmann"> Clemens Vinzenz Ullmann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lithium is recognized as the critical energy metal of the 21st century, comparable in importance to coal in the 19th century and oil in the 20th century, often termed 'white gold'. Current global demand for lithium, estimated at 0.95-0.98 million metric tons (Mt) of lithium carbonate equivalent (LCE) annually in 2024, is projected to rise to 1.87 Mt by 2027 and 3.06 Mt by 2030. Despite anticipated short-term stability in supply and demand, meeting the forecasted 2030 demand will require the lithium industry to develop an additional capacity of 1.42 Mt of LCE annually, exceeding current planned and ongoing efforts. Brine resources constitute nearly 65% of global lithium reserves, underscoring the importance of exploring lithium recovery from underutilized sources, especially geothermal brines. However, conventional lithium extraction from brine deposits faces challenges due to its time-intensive process, low efficiency (30-50% lithium recovery), unsuitability for low lithium concentrations (<300 mg/l), and notable environmental impacts. Addressing these challenges, direct lithium extraction (DLE) methods have emerged as promising technologies capable of economically extracting lithium even from low-concentration brines (>50 mg/l) with high recovery rates (75-98%). However, most studies (70%) have predominantly focused on synthetic brines instead of native (natural/real), with limited application of these approaches in real-world case studies or industrial settings. This study aims to bridge this gap by investigating a geothermal brine sample collected from a real case study site in the UK. A Mn-based lithium-ion sieve (LIS) adsorbent was synthesized and employed to selectively extract lithium from the sample brine. Adsorbents with a Li:Mn molar ratio of 1:1 demonstrated superior lithium selectivity and adsorption capacity. Furthermore, the pristine Mn-based adsorbent was modified through transition metals doping, resulting in enhanced lithium selectivity and adsorption capacity. The modified adsorbent exhibited a higher separation factor for lithium over major co-existing cations such as Ca, Mg, Na, and K, with separation factors exceeding 200. The adsorption behaviour was well-described by the Langmuir model, indicating monolayer adsorption, and the kinetics followed a pseudo-second-order mechanism, suggesting chemisorption at the solid surface. Thermodynamically, negative ΔG° values and positive ΔH° and ΔS° values were observed, indicating the spontaneity and endothermic nature of the adsorption process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20minerals" title=" critical minerals"> critical minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=DLE" title=" DLE"> DLE</a>, <a href="https://publications.waset.org/abstracts/search?q=geothermal%20brines" title=" geothermal brines"> geothermal brines</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemistry" title=" geochemistry"> geochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium" title=" lithium"> lithium</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20sieves" title=" lithium-ion sieves"> lithium-ion sieves</a> </p> <a href="https://publications.waset.org/abstracts/186911/selective-extraction-of-lithium-from-native-geothermal-brines-using-lithium-ion-sieves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186911.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">46</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">4</span> Processes Controlling Release of Phosphorus (P) from Catchment Soils and the Relationship between Total Phosphorus (TP) and Humic Substances (HS) in Scottish Loch Waters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaoyun%20Hui">Xiaoyun Hui</a>, <a href="https://publications.waset.org/abstracts/search?q=Fiona%20Gentle"> Fiona Gentle</a>, <a href="https://publications.waset.org/abstracts/search?q=Clemens%20Engelke"> Clemens Engelke</a>, <a href="https://publications.waset.org/abstracts/search?q=Margaret%20C.%20Graham"> Margaret C. Graham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although past work has shown that phosphorus (P), an important nutrient, may form complexes with aqueous humic substances (HS), the principal component of natural organic matter, the nature of such interactions is poorly understood. Humic complexation may not only enhance P concentrations but it may change its bioavailability within such waters and, in addition, influence its transport within catchment settings. This project is examining the relationships and associations of P, HS, and iron (Fe) in Loch Meadie, Sutherland, North Scotland, a mesohumic freshwater loch which has been assessed as reference condition with respect to P. The aim is to identify characteristic spectroscopic parameters which can enhance the performance of the model currently used to predict reference condition TP levels for highly-coloured Scottish lochs under the Water Framework Directive. In addition to Loch Meadie, samples from other reference condition lochs in north Scotland and Shetland were analysed. By including different types of reference condition lochs (clear water, mesohumic and polyhumic water) this allowed the relationship between total phosphorus (TP) and HS to be more fully explored. The pH, [TP], [Fe], UV/Vis absorbance/spectra, [TOC] and [DOC] for loch water samples have been obtained using accredited methods. Loch waters were neutral to slightly acidic/alkaline (pH 6-8). [TP] in loch waters were lower than 50 µg L-1, and in Loch Meadie waters were typically <10 µg L-1. [Fe] in loch waters were mainly <0.6 mg L-1, but for some loch water samples, [Fe] were in the range 1.0-1.8 mg L-1and there was a positive correlation with [TOC] (r2=0.61). Lochs were classified as clear water, mesohumic or polyhumic based on water colour. The range of colour values of sampled lochs in each category were 0.2–0.3, 0.2–0.5 and 0.5–0.8 a.u. (10 mm pathlength), respectively. There was also a strong positive correlation between [DOC] and water colour (R2=0.84). The UV/Vis spectra (200-700 nm) for water samples were featureless with only a slight “shoulder” observed in the 270–290 nm region. Ultrafiltration was then used to separate colloidal and truly dissolved components from the loch waters and, since it contained the majority of aqueous P and Fe, the colloidal component was fractionated by gel filtration chromatography method. Gel filtration chromatographic fractionation of the colloids revealed two brown-coloured bands which had distinctive UV/Vis spectral features. The first eluting band had larger and more aromatic HS molecules than the second band, and in addition both P and Fe were primarily associated with the larger, more aromatic HS. This result demonstrated that P was able to form complexes with Fe-rich components of HS, and thus provided a scientific basis for the significant correlation between [Fe] and [TP] that the previous monitoring data of reference condition lochs from Scottish Environment Protection Agency (SEPA) showed. The distinctive features of the HS will be used as the basis for an improved spectroscopic tool. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=total%20phosphorus" title="total phosphorus">total phosphorus</a>, <a href="https://publications.waset.org/abstracts/search?q=humic%20substances" title=" humic substances"> humic substances</a>, <a href="https://publications.waset.org/abstracts/search?q=Scottish%20loch%20water" title=" Scottish loch water"> Scottish loch water</a>, <a href="https://publications.waset.org/abstracts/search?q=WFD%20model" title=" WFD model "> WFD model </a> </p> <a href="https://publications.waset.org/abstracts/18131/processes-controlling-release-of-phosphorus-p-from-catchment-soils-and-the-relationship-between-total-phosphorus-tp-and-humic-substances-hs-in-scottish-loch-waters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18131.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">546</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">3</span> Performance Assessment of Ventilation Systems for Operating Theatres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clemens%20Bulitta">Clemens Bulitta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sasan%20Sadrizadeh"> Sasan Sadrizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Buhl"> Sebastian Buhl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Ventilation technology in operating theatres (OT)is internationally regulated by dif-ferent standards, which define basic specifications for technical equipment and many times also the necessary operating and performance parameters. This confronts the operators of healthcare facilities with the question of finding the best ventilation and air conditioning system for the OT in order to achieve the goal of a large and robust surgicalworkzone with appropriate air quality and climate for patient safety and occupational health. Additionally, energy consumption and the potential need for clothing that limits transmission of bacteria must be considered as well as the total life cycle cost. However, the evaluation methodology of ventilation systems regarding these matters are still a topic of discussion. To date, there are neither any uniform standardized specifications nor any common validation criteria established. Thus, this study aimed to review data in the literature and add ourown research results to compare and assess the performance of different ventilations systems regarding infection preventive effects, energy efficiency, and staff comfort. Methods: We have conducted a comprehensive literature review on OT ventilation-related topics to understand the strengths and limitations of different ventilation systems. Furthermore, data from experimental assessments on OT ventilation systems at the University of Amberg-Weidenin Germany were in-cluded to comparatively assess the performance of Laminar Airflow (LAF), Turbulent Mixing Air-flow(TMA), and Temperature-controlled Airflow (TcAF) with regards to patient and occupational safety as well as staff comfort including indoor climate.CFD simulations from the Royal Institute of Technology in Sweden (KTH) were also studied to visualize the differences between these three kinds of ventilation systems in terms of the size of the surgical workzone, resilience to obstacles in the airflow, and energy use. Results: A variety of ventilation concepts are in use in the OT today. Each has its advantages and disadvantages, and thus one may be better suited than another depend-ing on the built environment and clinical workflow. Moreover, the proper functioning of OT venti-lation is also affected by multiple external and internal interfering factors. Based on the available data TcAF and LAF seem to provide the greatest effects regarding infection control and minimizing airborne risks for surgical site infections without the need for very tight surgical clothing systems. Resilience to obstacles, staff comfort, and energy efficiency seem to be favourable with TcAF. Conclusion: Based on literature data in current publications and our studies at the Technical Uni-versity of Applied Sciences Amberg-Weidenand the Royal Institute of Technoclogy, LAF and TcAF are more suitable for minimizing the risk for surgical site infections leading to improved clin-ical outcomes. Nevertheless, regarding the best management of thermal loads, atmosphere, energy efficiency, and occupational safety, overall results and data suggest that TcAF systems could pro-vide the economically most efficient and clinically most effective solution under routine clinical conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ventilation%20systems" title="ventilation systems">ventilation systems</a>, <a href="https://publications.waset.org/abstracts/search?q=infection%20control" title=" infection control"> infection control</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=operating%20theatre" title=" operating theatre"> operating theatre</a>, <a href="https://publications.waset.org/abstracts/search?q=airborne%20infection%20risks" title=" airborne infection risks"> airborne infection risks</a> </p> <a href="https://publications.waset.org/abstracts/144738/performance-assessment-of-ventilation-systems-for-operating-theatres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144738.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">97</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">2</span> Real-Time Neuroimaging for Rehabilitation of Stroke Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerhard%20Gritsch">Gerhard Gritsch</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Skupch"> Ana Skupch</a>, <a href="https://publications.waset.org/abstracts/search?q=Manfred%20Hartmann"> Manfred Hartmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Wolfgang%20Fr%C3%BChwirt"> Wolfgang Frühwirt</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannes%20Perko"> Hannes Perko</a>, <a href="https://publications.waset.org/abstracts/search?q=Dieter%20Grossegger"> Dieter Grossegger</a>, <a href="https://publications.waset.org/abstracts/search?q=Tilmann%20Kluge"> Tilmann Kluge</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rehabilitation of stroke patients is dominated by classical physiotherapy. Nowadays, a field of research is the application of neurofeedback techniques in order to help stroke patients to get rid of their motor impairments. Especially, if a certain limb is completely paralyzed, neurofeedback is often the last option to cure the patient. Certain exercises, like the imagination of the impaired motor function, have to be performed to stimulate the neuroplasticity of the brain, such that in the neighboring parts of the injured cortex the corresponding activity takes place. During the exercises, it is very important to keep the motivation of the patient at a high level. For this reason, the missing natural feedback due to a movement of the effected limb may be replaced by a synthetic feedback based on the motor-related brain function. To generate such a synthetic feedback a system is needed which measures, detects, localizes and visualizes the motor related µ-rhythm. Fast therapeutic success can only be achieved if the feedback features high specificity, comes in real-time and without large delay. We describe such an approach that offers a 3D visualization of µ-rhythms in real time with a delay of 500ms. This is accomplished by combining smart EEG preprocessing in the frequency domain with source localization techniques. The algorithm first selects the EEG channel featuring the most prominent rhythm in the alpha frequency band from a so-called motor channel set (C4, CZ, C3; CP6, CP4, CP2, CP1, CP3, CP5). If the amplitude in the alpha frequency band of this certain electrode exceeds a threshold, a µ-rhythm is detected. To prevent detection of a mixture of posterior alpha activity and µ-activity, the amplitudes in the alpha band outside the motor channel set are not allowed to be in the same range as the main channel. The EEG signal of the main channel is used as template for calculating the spatial distribution of the µ - rhythm over all electrodes. This spatial distribution is the input for a inverse method which provides the 3D distribution of the µ - activity within the brain which is visualized in 3D as color coded activity map. This approach mitigates the influence of lid artifacts on the localization performance. The first results of several healthy subjects show that the system is capable of detecting and localizing the rarely appearing µ-rhythm. In most cases the results match with findings from visual EEG analysis. Frequent eye-lid artifacts have no influence on the system performance. Furthermore, the system will be able to run in real-time. Due to the design of the frequency transformation the processing delay is 500ms. First results are promising and we plan to extend the test data set to further evaluate the performance of the system. The relevance of the system with respect to the therapy of stroke patients has to be shown in studies with real patients after CE certification of the system.

Plants do not have a constant and steady distribution all around the world, and even plant species’ variations are not the same in one specific region. Presence of plants is not only limited to one field like botany; they exist in different fields such as literature and mythology and they hold useful and inestimable historical records. No one can imagine the world without oxygen which is produced mostly by plants. Their influences become more manifest since no other live species can exist on earth without plants as they form the basic food staples too. Regulation of water cycle and oxygen production are the other roles of plants. The roles affect environment and climate. Plants are the main components of agricultural activities. Many countries benefit from these activities. Therefore, plants have impacts on political and economic situations and future of countries. Due to importance of plants and their roles, study of plants is essential in various fields. Consideration of their different applications leads to focus on details of them too. Automatic recognition of plants is a novel field to contribute other researches and future of studies. Moreover, plants can survive their life in different places and regions by means of adaptations. Therefore, adaptations are their special factors to help them in hard life situations. Weather condition is one of the parameters which affect plants life and their existence in one area. Recognition of plants in different weather conditions is a new window of research in the field. Only natural images are usable to consider weather conditions as new factors. Thus, it will be a generalized and useful system. In order to have a general system, distance from the camera to plants is considered as another factor. The other considered factor is change of light intensity in environment as it changes during the day. Adding these factors leads to a huge challenge to invent an accurate and secure system. Development of an efficient plant recognition system is essential and effective. One important component of plant is leaf which can be used to implement automatic systems for plant recognition without any human interface and interaction. Due to the nature of used images, characteristic investigation of plants is done. Leaves of plants are the first characteristics to select as trusty parts. Four different plant species are specified for the goal to classify them with an accurate system. The current paper is devoted to principal directions of the proposed methods and implemented system, image dataset, and results. The procedure of algorithm and classification is explained in details. First steps, feature detection and description of visual information, are outperformed by using Scale invariant feature transform (SIFT), HARRIS-SIFT, and FAST-SIFT methods. The accuracy of the implemented methods is computed. In addition to comparison, robustness and efficiency of results in different conditions are investigated and explained. <p class="card-text"><strong>Keywords:</strong> <a
