wide field of applications. Their types range from household robots over workshop robots to autonomous cars and many more. All of them undergo a number of testing steps during development, production and maintenance. This paper describes an approach to improve testing of robot behavior. It was inspired by the RoboCup @work competition that itself reflects a robotics benchmark for industrial robotics. There, scaled down versions of mobile industrial robots have to navigate through a workshop-like environment or operation area and have to perform tasks of manipulating and transporting work pieces. This paper will introduce an approach of automated vision-based testing of the behavior of the so called youBot robot, which is the most widely used robot platform in the RoboCup @work competition. The proposed system allows automated testing of multiple tries of the robot to perform a specific missions and it allows for the flexibility of the robot, e.g. selecting different paths between two tasks within a mission. The approach is based on a multi-camera setup using, off the shelf cameras and optical markers. It has been applied for test-driven development (TDD) and maintenance-like verification of the robot behavior and performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supervisory%20control" title="supervisory control">supervisory control</a>, <a href="https://publications.waset.org/abstracts/search?q=testing" title=" testing"> testing</a>, <a href="https://publications.waset.org/abstracts/search?q=markers" title=" markers"> markers</a>, <a href="https://publications.waset.org/abstracts/search?q=mono%20vision" title=" mono vision"> mono vision</a>, <a href="https://publications.waset.org/abstracts/search?q=automation" title=" automation"> automation</a> </p> <a href="https://publications.waset.org/abstracts/8364/automated-testing-of-workshop-robot-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8364.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">377</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">281</span> Sainte Sophie Landfill: Field-Scale Assessment of Municipal Solid Waste Mechanical Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wameed%20Alghazali">Wameed Alghazali</a>, <a href="https://publications.waset.org/abstracts/search?q=Shawn%20Kenny"> Shawn Kenny</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20J.%20Van%20Geel"> Paul J.

Mechanical settlement is governed by the physical characteristics of MSW and the applied overburden pressure. Several research studies used oedometers and different size compression cells to evaluate the primary and mechanical creep compression indices/ratios. However, MSW is known for its heterogeneity, which means data obtained from laboratory testing are not necessary to be a good representation of the mechanical response observed in the field. Furthermore, most of the laboratory tests found in the literature were conducted on shredded samples of MSW to obtain specimens that are suitable for the testing setup. It is believed that shredding MSW samples changes the physical and mechanical properties of the waste. In this study, settlement field data was collected during the filling stage of Ste. Sophie landfill was used to estimate the primary and mechanical creep compression ratios. The field results from Ste. Sophie landfill indicated that both the primary and mechanical creep compression ratios of MSW are not constants but decrease with the increase in the applied vertical stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical%20creep%20compression%20ratio" title="mechanical creep compression ratio">mechanical creep compression ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=municipal%20solid%20waste" title=" municipal solid waste"> municipal solid waste</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20compression%20ratio" title=" primary compression ratio"> primary compression ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20level" title=" stress level"> stress level</a> </p> <a href="https://publications.waset.org/abstracts/162606/sainte-sophie-landfill-field-scale-assessment-of-municipal-solid-waste-mechanical-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162606.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">280</span> Employing Innovative Pedagogy: Collaborative (Online) Learning and Teaching In An International Setting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sonja%20G%C3%B6gele">Sonja Gögele</a>, <a href="https://publications.waset.org/abstracts/search?q=Petra%20Kletzenbauer"> Petra Kletzenbauer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> International strategies are ranked as one of the core activities in the development plans of Austrian universities. This has led to numerous promising activities in terms of internationalization (i.e. development of international degree programmes, increased staff, and student mobility, and blended international projects). The latest innovative approach are so called Blended Intensive Programmes (BIP), which combine jointly delivered teaching and learning elements of at least three participating ERASMUS universities in a virtual and short-term mobility setup. Students who participate in BIP can maintain their study plans at their home institution and include BIP as a parallel activity. This paper presents the experiences of this programme on the topic of sustainable computing hosted by the University of Applied Sciences FH JOANNEUM. By means of an online survey and face-to-face interviews with all stakeholders (20 students, 8 professors), the empirical study addresses the challenges of hosting an international blended learning programme (i.e. virtual phase and on-site intensive phase) and discusses the impact of such activities in terms of innovative pedagogy (i.e. virtual collaboration, research-based learning). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internationalization" title="internationalization">internationalization</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20learning" title=" collaborative learning"> collaborative learning</a>, <a href="https://publications.waset.org/abstracts/search?q=blended%20intensive%20programme" title=" blended intensive programme"> blended intensive programme</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a> </p> <a href="https://publications.waset.org/abstracts/154674/employing-innovative-pedagogy-collaborative-online-learning-and-teaching-in-an-international-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154674.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">279</span> Analysing Maximum Power Point Tracking in a Stand Alone Photovoltaic System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osamede%20Asowata">Osamede Asowata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Optimized gain in respect to output power of stand-alone photovoltaic (PV) systems is one of the major focus of PV in recent times. This is evident in its low carbon emission and efficiency. Power failure or outage from commercial providers, in general, does not promote development to public and private sector; these basically limit the development of industries. The need for a well-structured PV system is of importance for an efficient and cost effective monitoring system. The purpose of this paper is to validate the maximum power point of an off-grid PV system taking into consideration the most effective tilt and orientation angles for PV's in the southern hemisphere. This paper is based on analyzing the system using a solar charger with maximum power point tracking (MPPT) from a pulse width modulation (PWM) perspective. The power conditioning device chosen is a solar charger with MPPT. The practical setup consists of a PV panel that is set to an orientation angle of 0°N, with a corresponding tilt angle of 36°, 26°, and 16°. Preliminary results include regression analysis (normal probability plot) showing the maximum power point in the system as well the best tilt angle for maximum power point tracking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=poly-crystalline%20PV%20panels" title="poly-crystalline PV panels">poly-crystalline PV panels</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20chargers" title=" solar chargers"> solar chargers</a>, <a href="https://publications.waset.org/abstracts/search?q=tilt%20and%20orientation%20angles" title=" tilt and orientation angles"> tilt and orientation angles</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20power%20point%20tracking" title=" maximum power point tracking"> maximum power point tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=MPPT" title=" MPPT"> MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=Pulse%20Width%20Modulation%20%28PWM%29." title=" Pulse Width Modulation (PWM)."> Pulse Width Modulation (PWM).</a> </p> <a href="https://publications.waset.org/abstracts/98767/analysing-maximum-power-point-tracking-in-a-stand-alone-photovoltaic-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98767.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">278</span> Outdoor Anomaly Detection with a Spectroscopic Line Detector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20J.%20G.%20Somsen">O. J. G. Somsen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the tasks of optical surveillance is to detect anomalies in large amounts of image data. However, if the size of the anomaly is very small, limited information is available to distinguish it from the surrounding environment. Spectral detection provides a useful source of additional information and may help to detect anomalies with a size of a few pixels or less. Unfortunately, spectral cameras are expensive because of the difficulty of separating two spatial in addition to one spectral dimension. We investigate the possibility of modifying a simpler spectral line detector for outdoor detection. This may be especially useful if the area of interest forms a line, such as the horizon. We use a monochrome CCD that also enables detection into the near infrared. A simple camera is attached to the setup to determine which part of the environment is spectrally imaged. Our preliminary results indicate that sensitive detection of very small targets is indeed possible. Spectra could be taken from the various targets by averaging columns in the line image. By imaging a set of lines of various width we found narrow lines that could not be seen in the color image but remained visible in the spectral line image. A simultaneous analysis of the entire spectra can produce better results than visual inspection of the line spectral image. We are presently developing calibration targets for spatial and spectral focusing and alignment with the spatial camera. This will present improved results and more use in outdoor application <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anomaly%20detection" title="anomaly detection">anomaly detection</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopic%20line%20imaging" title=" spectroscopic line imaging"> spectroscopic line imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20analysis" title=" image analysis"> image analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=outdoor%20detection" title=" outdoor detection "> outdoor detection </a> </p> <a href="https://publications.waset.org/abstracts/34329/outdoor-anomaly-detection-with-a-spectroscopic-line-detector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34329.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">481</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">277</span> Understanding ASPECTS of Stroke: Interrater Reliability between Emergency Medicine Physician and Radiologist in a Rural Setup</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vineel%20Inampudi">Vineel Inampudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arjun%20Prakash"> Arjun Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Vinod"> Joseph Vinod</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aims and Objectives: To evaluate the interrater reliability in grading ASPECTS score, between emergency medicine physician at first contact and radiologist among patients with acute ischemic stroke. Materials and Methods: We conducted a retrospective analysis of 86 acute ischemic stroke cases referred to the Department of Radiodiagnosis during November 2014 to January 2016. The imaging (plain CT scan) was performed using GE Bright Speed Elite 16 Slice CT Scanner. ASPECTS score was calculated separately by an emergency medicine physician and radiologist. Interrater reliability for total and dichotomized ASPECTS (≥ 6 and < 6) scores were assessed using statistical analysis (ICC and Cohen ĸ coefficients) on SPSS software (v17.0). Results: Interrater agreement for total and dichotomized ASPECTS was substantial (ICC 0.79 and Cohen ĸ 0.68) between the emergency physician and radiologist. Mean difference in ASPECTS between the two readers was only 0.15 with standard deviation of 1.58. No proportionality bias was detected. Bland Altman plot was constructed to demonstrate the distribution of ASPECT differences between the two readers. Conclusion: Substantial interrater agreement was noted in grading ASPECTS between emergency medicine physician at first contact and radiologist thereby confirming its robustness even in a rural setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ASPECTS" title="ASPECTS">ASPECTS</a>, <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography" title=" computed tomography"> computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=MCA%20territory" title=" MCA territory"> MCA territory</a>, <a href="https://publications.waset.org/abstracts/search?q=stroke" title=" stroke"> stroke</a> </p> <a href="https://publications.waset.org/abstracts/96351/understanding-aspects-of-stroke-interrater-reliability-between-emergency-medicine-physician-and-radiologist-in-a-rural-setup" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96351.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">276</span> Air-Blast Ultrafast Disconnectors and Solid-State Medium Voltage DC Breaker: A Modified Version to Lower Losses and Higher Speed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kadivar">Ali Kadivar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaveh%20Niayesh"> Kaveh Niayesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> MVDC markets for green power generations, Navy, subsea oil and gas electrification, and transportation electrification are extending rapidly. The lack of fast and powerful DC circuit breakers (CB) is the most significant barrier to realizing the medium voltage DC (MVDC) networks. A concept of hybrid circuit breakers (HCBs) benefiting from ultrafast disconnectors (UFD) is proposed. A set of mechanical switches substitute the power electronic commutation switches to reduce the losses during normal operation in HCB. The success of current commutation in such breakers relies on the behaviour of elongated, wall constricted arcs during the opening across the contacts inside the UFD. The arc voltage dependencies on the contact speed of UFDs is discussed through multiphysics simulations contact opening speeds of 10, 20 and 40 m/s. The arc voltage at a given current increases exponentially with the contact opening velocity. An empirical equation for the dynamic arc characteristics is presented for the tested UFD, and the experimentally verfied characteristics for voltage-current are utilized for the current commutation simulation prior to apply on a 14 kV experimental setup. Different failures scenarios due to the current commutation are investigated <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MVDC%20breakers" title="MVDC breakers">MVDC breakers</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20circuit%20breaker" title=" DC circuit breaker"> DC circuit breaker</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20operating%20breaker" title=" fast operating breaker"> fast operating breaker</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra-fast%20elongated%20arc" title=" ultra-fast elongated arc"> ultra-fast elongated arc</a> </p> <a href="https://publications.waset.org/abstracts/171231/air-blast-ultrafast-disconnectors-and-solid-state-medium-voltage-dc-breaker-a-modified-version-to-lower-losses-and-higher-speed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171231.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">83</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">275</span> Arduino-Based Laser Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simon%20Bambey">Simon Bambey</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Lim"> Edward Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai%20Corley-Jory"> Kai Corley-Jory</a>, <a href="https://publications.waset.org/abstracts/search?q=Pooya%20Taheri"> Pooya Taheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal of this paper is to propose a simple and low-cost microcontroller-based laser communication link. To demonstrate that laser communication is a viable and efficient means for transmitting data, a transceiver capable of transfer rates of approximately 0.7 kB/s is prototyped. The hardware used for the transceiver consists of Commercial Off-The-Shelf (COTS) lasers, photodiodes, and the Arduino Mega 2560 which is an open-source and easy-to-use microcontroller-based platform intended for making interactive projects. A graphic user interface utilizing the Meteor framework is developed to facilitate the communication between the user and transceiver. The developed transceiver prototype is capable of receiving and transmitting data at significant ranges with no loss of information. Furthermore, stable and secure communication is achieved through several mechanisms developed to manage simultaneous sending and receiving, in addition to detecting physical interruptions during transmission. The design setup is scalable and with further development can be transformed into a fiber-optic transmission system. Due to its nature, laser communication is very secure and can provide a safe and private communication link.

The details of the test setup and procedures were illustrated. The results obtained from the experimental tests were discussed which include the observation of cracking patterns and influence of aspect ratio (L/b). Analytical study of ﬁnite element analysis was implemented and degree of composite action of the test panels was also examined in both experimental and analytical studies. Result shows that crack patterns appeared in only one-direction, similar to reports on solid slabs, particularly when both concrete wythes act in a composite manner. Foamed concrete was briefly reviewed and experimental results were compared with the ﬁnite element analyses data which gives a reasonable degree of accuracy. Therefore, based on the results obtained, PFCSP slab can be used as an alternative to conventional flooring system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspect%20ratio%20%28L%2Fb%29" title="aspect ratio (L/b)">aspect ratio (L/b)</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analyses%20%28FEA%29" title=" finite element analyses (FEA)"> finite element analyses (FEA)</a>, <a href="https://publications.waset.org/abstracts/search?q=foamed%20concrete%20%28FC%29" title=" foamed concrete (FC)"> foamed concrete (FC)</a>, <a href="https://publications.waset.org/abstracts/search?q=precast%20foamed%20concrete%20sandwich%20panel%20%28PFCSP%29" title=" precast foamed concrete sandwich panel (PFCSP)"> precast foamed concrete sandwich panel (PFCSP)</a>, <a href="https://publications.waset.org/abstracts/search?q=ultimate%20flexural%20strength%20capacity" title=" ultimate flexural strength capacity"> ultimate flexural strength capacity</a> </p> <a href="https://publications.waset.org/abstracts/42153/structural-behavior-of-laterally-loaded-precast-foamed-concrete-sandwich-panel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42153.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">314</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">273</span> Effect of Fluidized Granular Activated Carbon for the Mitigation of Membrane Fouling in Wastewater Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingwei%20Wang">Jingwei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthony%20G.%20Fane"> Anthony G.

It has been affirmed that the unsteady-state tangential shear conferred by GAC fluidization on membrane surface suppressed the extent of membrane fouling with energy consumption much lower than that of bubbling (i.e., air sparging). In a previous work, the hydrodynamics of the fluidized GAC particles were correlated with membrane fouling mitigation effectiveness. Results verified that the momentum transfer from particle to membrane held a key in fouling mitigation. The goal of the current work is to understand the effect of fluidized GAC on membrane critical flux. Membrane critical flux values were measured by a vertical Direct Observation Through the Membrane (DOTM) setup. The polystyrene particles (known as latex particles) with the particle size of 5 µm were used as model foulant thus to give the number of the foulant on the membrane surface. Our results shed light on the positive effect of fluidized GAC enhancing the critical membrane flux by an order-of-magnitude as compared to that of liquid shear alone. Membrane fouling mitigation was benefitted by the increasing of power input. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=membrane%20fouling%20mitigation" title="membrane fouling mitigation">membrane fouling mitigation</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid-solid%20fluidization" title=" liquid-solid fluidization"> liquid-solid fluidization</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20flux" title=" critical flux"> critical flux</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20input" title=" energy input"> energy input</a> </p> <a href="https://publications.waset.org/abstracts/75555/effect-of-fluidized-granular-activated-carbon-for-the-mitigation-of-membrane-fouling-in-wastewater-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75555.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">407</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">272</span> Storage Tank Overfill Protection in Compliance with Functional Safety Standard: IEC 61511</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Alsada">Hassan Alsada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tank overfill accidents are major concerns for industries handling large volumes of hydrocarbons. Buncefield, Jaipur, Puerto Rico, and West Virginia are just a few accidents with catastrophic consequences. Thus, it is very important for any industry to take the right safety measures for overfill prevention. Moreover, one of the main causative factors in the overfill accidents was inadequate risk analysis and, subsequently, inadequate design. This study aims to provide a full assessment in accordance with the Functional safety standard: “IEC 615 11 – Safety instrumented systems for the process industry” to the tank overfill scenario according to the standard’s Safety Life Cycle (SLC), which includes: the analysis phase, the implementation phase, and the operation phase. The paper discusses in depth the tank overfills Independent Protection Layers (IPLs) with systematic analysis to avoid the safety risks of under-design and the financial risk of facility overdesign. The result shows a clear and systematic assessment in compliance with the standards that can help to assist existing tank overfilling setup or a guide to support designing new storage facilities overfill protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IEC%2061511" title="IEC 61511">IEC 61511</a>, <a href="https://publications.waset.org/abstracts/search?q=PHA" title=" PHA"> PHA</a>, <a href="https://publications.waset.org/abstracts/search?q=LOPA" title=" LOPA"> LOPA</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20safety" title=" process safety"> process safety</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20instrumented%20systems" title=" safety instrumented systems"> safety instrumented systems</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20instrumented%20function" title=" safety instrumented function"> safety instrumented function</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20safety" title=" functional safety"> functional safety</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20life%20cycle" title=" safety life cycle"> safety life cycle</a> </p> <a href="https://publications.waset.org/abstracts/160747/storage-tank-overfill-protection-in-compliance-with-functional-safety-standard-iec-61511" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">271</span> Principle Components Updates via Matrix Perturbations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aiman%20Elragig">Aiman Elragig</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Dreiwi"> Hanan Dreiwi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dung%20Ly"> Dung Ly</a>, <a href="https://publications.waset.org/abstracts/search?q=Idriss%20Elmabrook"> Idriss Elmabrook</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper highlights a new approach to look at online principle components analysis (OPCA).

Climate function at automobile is an important variable for thermal comfort. In the experimental study localized heating and cooling performances have been examined with the aid of a mechanism established to a vehicle. The equipment’s used in the experimental setup/mechanism have been provided and assembled. During the measurement, the status of the performance level has been determined. Input parameters revolutions per minute and time; output parameters car seat cooling temperature, car back cooling temperature, car seat heating temperature, car back heating temperature were described by RBMTF if-the rules. Numerical parameters of input and output variables were fuzzificated as linguistic variables: Very Very Low (L1), Very Low (L2), Low (L3), Negative Medium (L4), Medium (L5), High (L7), Very High (L8) and Very Very High (L9) linguistic classes. The comparison between experimental data and RBMTF is done by using statistical methods like absolute fraction of variance (R2). The actual values and RBMTF results indicated that RBMTF could be successfully used in standard car air conditioning system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning%20system" title="air conditioning system">air conditioning system</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling-heating" title=" cooling-heating"> cooling-heating</a>, <a href="https://publications.waset.org/abstracts/search?q=RMBTF%20modelling" title=" RMBTF modelling"> RMBTF modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=car%20seat" title=" car seat"> car seat</a> </p> <a href="https://publications.waset.org/abstracts/39821/the-fuzzy-logic-modeling-of-performance-driver-seats-localised-cooling-and-heating-in-standard-car-air-conditioning-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39821.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">353</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">269</span> Theoretical and Experimental Investigation of the Interaction Behavior of a Bouncing Ball upon a Flexible Surface Impacted in Two Dimensions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wiwat%20Chumai">Wiwat Chumai</a>, <a href="https://publications.waset.org/abstracts/search?q=Perawit%20Boonsomchua"> Perawit Boonsomchua</a>, <a href="https://publications.waset.org/abstracts/search?q=Kanjana%20Ongkasin"> Kanjana Ongkasin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ball bouncing problem is a well-known problem in physics involving a ball dropped from a height to the ground. In this paper, the work investigates the theoretical and experimental setup that describes the dynamics of a rigid body on a chaotic elastic surface under air-damp conditions. Examination of four different types of balls is made, including marble, metal ball, tennis ball, and ping-pong ball. In this experiment, the effect of impact velocities is not considered; the ball is dropped from a fixed height. The method in this work employs the Rayleigh Dissipation Function to specify the effects of dissipative forces in Lagrangian mechanics. Our discoveries reveal that the dynamics of the ball exhibit horizontal motion while damping oscillation occurs, forming the destabilization in vertical pinch-off motion. Moreover, rotational motion is studied. According to the investigation of four different balls, the outcomes illustrate that greater mass results in more frequent dynamics, and the experimental results at some points align with the theoretical model. This knowledge contributes to our understanding of the complex fluid system and could serve as a foundation for further developments in water droplet simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=droplet" title="droplet">droplet</a>, <a href="https://publications.waset.org/abstracts/search?q=damping%20oscillation" title=" damping oscillation"> damping oscillation</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20damping%20oscillation" title=" nonlinear damping oscillation"> nonlinear damping oscillation</a>, <a href="https://publications.waset.org/abstracts/search?q=bouncing%20ball%20problem" title=" bouncing ball problem"> bouncing ball problem</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20surface" title=" elastic surface"> elastic surface</a> </p> <a href="https://publications.waset.org/abstracts/186488/theoretical-and-experimental-investigation-of-the-interaction-behavior-of-a-bouncing-ball-upon-a-flexible-surface-impacted-in-two-dimensions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186488.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">100</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">268</span> Artificial Intelligence in Penetration Testing of a Connected and Autonomous Vehicle Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phillip%20Garrad">Phillip Garrad</a>, <a href="https://publications.waset.org/abstracts/search?q=Saritha%20Unnikrishnan"> Saritha Unnikrishnan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recent popularity of connected and autonomous vehicles (CAV) corresponds with an increase in the risk of cyber-attacks. These cyber-attacks have been instigated by both researchers or white-coat hackers and cyber-criminals. As Connected Vehicles move towards full autonomy, the impact of these cyber-attacks also grows. The current research details challenges faced in cybersecurity testing of CAV, including access and cost of the representative test setup. Other challenges faced are lack of experts in the field. Possible solutions to how these challenges can be overcome are reviewed and discussed. From these findings, a software simulated CAV network is established as a cost-effective representative testbed. Penetration tests are then performed on this simulation, demonstrating a cyber-attack in CAV. Studies have shown Artificial Intelligence (AI) to improve runtime, increase efficiency and comprehensively cover all the typical test aspects in penetration testing in other industries. There is an attempt to introduce similar AI models to the software simulation. The expectation from this implementation is to see similar improvements in runtime and efficiency for the CAV model. If proven to be an effective means of penetration test for CAV, this methodology may be used on a full CAV test network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title="cybersecurity">cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=connected%20vehicles" title=" connected vehicles"> connected vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20simulation" title=" software simulation"> software simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=penetration%20testing" title=" penetration testing"> penetration testing</a> </p> <a href="https://publications.waset.org/abstracts/144766/artificial-intelligence-in-penetration-testing-of-a-connected-and-autonomous-vehicle-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144766.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">110</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">267</span> High-Tech Based Simulation and Analysis of Maximum Power Point in Energy System: A Case Study Using IT Based Software Involving Regression Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enemeri%20George%20Uweiyohowo">Enemeri George Uweiyohowo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Improved achievement with respect to output control of photovoltaic (PV) systems is one of the major focus of PV in recent times. This is evident to its low carbon emission and efficiency. Power failure or outage from commercial providers, in general, does not promote development to public and private sector, these basically limit the development of industries. The need for a well-structured PV system is of importance for an efficient and cost-effective monitoring system. The purpose of this paper is to validate the maximum power point of an off-grid PV system taking into consideration the most effective tilt and orientation angles for PV's in the southern hemisphere. This paper is based on analyzing the system using a solar charger with MPPT from a pulse width modulation (PWM) perspective. The power conditioning device chosen is a solar charger with MPPT. The practical setup consists of a PV panel that is set to an orientation angle of 0∘N, with a corresponding tilt angle of 36∘, 26∘ and 16∘. Preliminary results include regression analysis (normal probability plot) showing the maximum power point in the system as well the best tilt angle for maximum power point tracking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=poly-crystalline%20PV%20panels" title="poly-crystalline PV panels">poly-crystalline PV panels</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20technology%20%28IT%29" title=" information technology (IT)"> information technology (IT)</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20power%20point%20tracking%20%28MPPT%29" title=" maximum power point tracking (MPPT)"> maximum power point tracking (MPPT)</a>, <a href="https://publications.waset.org/abstracts/search?q=pulse%20width%20modulation%20%28PWM%29" title=" pulse width modulation (PWM)"> pulse width modulation (PWM)</a> </p> <a href="https://publications.waset.org/abstracts/89070/high-tech-based-simulation-and-analysis-of-maximum-power-point-in-energy-system-a-case-study-using-it-based-software-involving-regression-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89070.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">213</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">266</span> The Impact of Quality Management System Establishment over the Performance of Public Administration Services in Kosovo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilir%20Rexhepi">Ilir Rexhepi</a>, <a href="https://publications.waset.org/abstracts/search?q=Naim%20Ismajli"> Naim Ismajli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quality and quality management are key factors of success nowadays. Public sector and quality management in this sector contains many challenges and difficulties, most notably in a new country like Kosovo. This study analyses the process of implementation of quality management system in public administration institutions in this country. The main objective is to show how to set up a quality management system and how does the quality management system setup affect the overall public administration services in Kosovo. This study shows how the efficiency and effectiveness of public institution services/performance is rapidly improving through the establishment and functionalization of Quality Management System. The specific impact of established QMC within the organization has resulted with the identification of mission related processes within the entire system including input identification, the person in charge and the way of conversion to the output of each activity though the interference with other service processes within the system. By giving detailed analyses of all steps of implementation of the Quality Management System, its effect and consequences towards the overall public institution service performance, we try to go one step further, by showing it as a very good example or tool of other public institutions for improving their service performance. Interviews with employees, middle and high level managers including the quality manager and general secretaries are also part of analyses in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality" title="quality">quality</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20management%20system" title=" quality management system"> quality management system</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20administration%20institutions" title=" public administration institutions"> public administration institutions</a> </p> <a href="https://publications.waset.org/abstracts/8430/the-impact-of-quality-management-system-establishment-over-the-performance-of-public-administration-services-in-kosovo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8430.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">282</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">265</span> Advanced Technologies for Detector Readout in Particle Physics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Venturini">Y.

The first product of the family is the VX2740 (64 ch, 125 MS/s, 16 bit) for advanced waveform recording and Digital Pulse Processing, fitting with the special requirements of Dark Matter and Neutrino experiments. In parallel, CAEN is developing the FERS-5200 platform, a Front-End Readout System designed to read out large multi-detector arrays, such as SiPMs, multi-anode PMTs, silicon strip detectors, wire chambers, GEM, gas tubes, and others. This is a highly-scalable distributed platform, based on small Front-End cards synchronized and read out by a concentrator board, allowing to build extremely large experimental setup. We plan to develop a complete family of cost-effective Front-End cards tailored to specific detectors and applications. The first one available is the A5202, a 64-channel unit for SiPM readout based on CITIROC ASIC by Weeroc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dark%20matter" title="dark matter">dark matter</a>, <a href="https://publications.waset.org/abstracts/search?q=digitizers" title=" digitizers"> digitizers</a>, <a href="https://publications.waset.org/abstracts/search?q=front-end%20electronics" title=" front-end electronics"> front-end electronics</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20FPGA" title=" open FPGA"> open FPGA</a>, <a href="https://publications.waset.org/abstracts/search?q=SiPM" title=" SiPM"> SiPM</a> </p> <a href="https://publications.waset.org/abstracts/131194/advanced-technologies-for-detector-readout-in-particle-physics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131194.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">128</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">264</span> Study of Natural Patterns on Digital Image Correlation Using Simulation Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gang%20Li">Gang Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghulam%20Mubashar%20Hassan"> Ghulam Mubashar Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Arcady%20Dyskin"> Arcady Dyskin</a>, <a href="https://publications.waset.org/abstracts/search?q=Cara%20MacNish"> Cara MacNish </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital image correlation (DIC) is a contactless full-field displacement and strain reconstruction technique commonly used in the field of experimental mechanics. Comparing with physical measuring devices, such as strain gauges, which only provide very restricted coverage and are expensive to deploy widely, the DIC technique provides the result with full-field coverage and relative high accuracy using an inexpensive and simple experimental setup. It is very important to study the natural patterns effect on the DIC technique because the preparation of the artificial patterns is time consuming and hectic process. The objective of this research is to study the effect of using images having natural pattern on the performance of DIC. A systematical simulation method is used to build simulated deformed images used in DIC. A parameter (subset size) used in DIC can have an effect on the processing and accuracy of DIC and even cause DIC to failure. Regarding to the picture parameters (correlation coefficient), the higher similarity of two subset can lead the DIC process to fail and make the result more inaccurate. The pictures with good and bad quality for DIC methods have been presented and more importantly, it is a systematic way to evaluate the quality of the picture with natural patterns before they install the measurement devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Digital%20Image%20Correlation%20%28DIC%29" title="Digital Image Correlation (DIC)">Digital Image Correlation (DIC)</a>, <a href="https://publications.waset.org/abstracts/search?q=deformation%20simulation" title=" deformation simulation"> deformation simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20pattern" title=" natural pattern"> natural pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=subset%20size" title=" subset size"> subset size</a> </p> <a href="https://publications.waset.org/abstracts/18727/study-of-natural-patterns-on-digital-image-correlation-using-simulation-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18727.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">420</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">263</span> Methods of Variance Estimation in Two-Phase Sampling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raghunath%20Arnab">Raghunath Arnab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The two-phase sampling which is also known as double sampling was introduced in 1938. In two-phase sampling, samples are selected in phases. In the first phase, a relatively large sample of size is selected by some suitable sampling design and only information on the auxiliary variable is collected. During the second phase, a sample of size is selected either from, the sample selected in the first phase or from the entire population by using a suitable sampling design and information regarding the study and auxiliary variable is collected. Evidently, two phase sampling is useful if the auxiliary information is relatively easy and cheaper to collect than the study variable as well as if the strength of the relationship between the variables and is high. If the sample is selected in more than two phases, the resulting sampling design is called a multi-phase sampling. In this article we will consider how one can use data collected at the first phase sampling at the stages of estimation of the parameter, stratification, selection of sample and their combinations in the second phase in a unified setup applicable to any sampling design and wider classes of estimators. The problem of the estimation of variance will also be considered. The variance of estimator is essential for estimating precision of the survey estimates, calculation of confidence intervals, determination of the optimal sample sizes and for testing of hypotheses amongst others. Although, the variance is a non-negative quantity but its estimators may not be non-negative. If the estimator of variance is negative, then it cannot be used for estimation of confidence intervals, testing of hypothesis or measure of sampling error. The non-negativity properties of the variance estimators will also be studied in details. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auxiliary%20information" title="auxiliary information">auxiliary information</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20sampling" title=" two-phase sampling"> two-phase sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=varying%20probability%20sampling" title=" varying probability sampling"> varying probability sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=unbiased%20estimators" title=" unbiased estimators"> unbiased estimators</a> </p> <a href="https://publications.waset.org/abstracts/36087/methods-of-variance-estimation-in-two-phase-sampling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36087.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">588</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">262</span> Generalized Vortex Lattice Method for Predicting Characteristics of Wings with Flap and Aileron Deflection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mondher%20Yahyaoui">Mondher Yahyaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A generalized vortex lattice method for complex lifting surfaces with flap and aileron deflection is formulated. The method is not restricted by the linearized theory assumption and accounts for all standard geometric lifting surface parameters: camber, taper, sweep, washout, dihedral, in addition to flap and aileron deflection. Thickness is not accounted for since the physical lifting body is replaced by a lattice of panels located on the mean camber surface. This panel lattice setup and the treatment of different wake geometries is what distinguish the present work form the overwhelming majority of previous solutions based on the vortex lattice method. A MATLAB code implementing the proposed formulation is developed and validated by comparing our results to existing experimental and numerical ones and good agreement is demonstrated. It is then used to study the accuracy of the widely used classical vortex-lattice method. It is shown that the classical approach gives good agreement in the clean configuration but is off by as much as 30% when a flap or aileron deflection of 30° is imposed. This discrepancy is mainly due the linearized theory assumption associated with the conventional method. A comparison of the effect of four different wake geometries on the values of aerodynamic coefficients was also carried out and it is found that the choice of the wake shape had very little effect on the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aileron%20deflection" title="aileron deflection">aileron deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=camber-surface-bound%20vortices" title=" camber-surface-bound vortices"> camber-surface-bound vortices</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20VLM" title=" classical VLM"> classical VLM</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20VLM" title=" generalized VLM"> generalized VLM</a>, <a href="https://publications.waset.org/abstracts/search?q=flap%20deflection" title=" flap deflection"> flap deflection</a> </p> <a href="https://publications.waset.org/abstracts/9274/generalized-vortex-lattice-method-for-predicting-characteristics-of-wings-with-flap-and-aileron-deflection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9274.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">435</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">261</span> The Design and Implementation of a Calorimeter for Evaluation of the Thermal Performance of Materials: The Case of Phase Change Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Solgi">Ebrahim Solgi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Hamedani"> Zahra Hamedani</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrouz%20Mohammad%20Kari"> Behrouz Mohammad Kari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruwan%20Fernando"> Ruwan Fernando</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Skates"> Henry Skates</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of thermal energy storage (TES) as part of a passive design strategy can reduce a building’s energy demand. TES materials do this by increasing the lag between energy consumption and energy supply by absorbing, storing and releasing energy in a controlled manner. The increase of lightweight construction in the building industry has made it harder to utilize thermal mass. Consequently, Phase Change Materials (PCMs) are a promising alternative as they can be manufactured in thin layers and used with lightweight construction to store latent heat. This research investigates utilizing PCMs, with the first step being measuring their performance under experimental conditions. To do this requires three components. The first is a calorimeter for measuring indoor thermal conditions, the second is a pyranometer for recording the solar conditions: global, diffuse and direct radiation and the third is a data-logger for recording temperature and humidity for the studied period. This paper reports on the design and implementation of an experimental setup used to measure the thermal characteristics of PCMs as part of a wall construction. The experimental model has been simulated with the software EnergyPlus to create a reliable simulation model that warrants further investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20change%20materials" title="phase change materials">phase change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=EnergyPlus" title=" EnergyPlus"> EnergyPlus</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20evaluation" title=" experimental evaluation"> experimental evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=night%20ventilation" title=" night ventilation"> night ventilation</a> </p> <a href="https://publications.waset.org/abstracts/89358/the-design-and-implementation-of-a-calorimeter-for-evaluation-of-the-thermal-performance-of-materials-the-case-of-phase-change-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89358.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">256</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">260</span> Revolutionizing Gaming Setup Design: Utilizing Generative and Iterative Methods to Prop and Environment Design, Transforming the Landscape of Game Development Through Automation and Innovation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rashmi%20Malik">Rashmi Malik</a>, <a href="https://publications.waset.org/abstracts/search?q=Videep%20Mishra"> Videep Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The practice of generative design has become a transformative approach for an efficient way of generating multiple iterations for any design project. The conventional way of modeling the game elements is very time-consuming and requires skilled artists to design. A 3D modeling tool like 3D S Max, Blender, etc., is used traditionally to create the game library, which will take its stipulated time to model. The study is focused on using the generative design tool to increase the efficiency in game development at the stage of prop and environment generation. This will involve procedural level and customized regulated or randomized assets generation. The paper will present the system design approach using generative tools like Grasshopper (visual scripting) and other scripting tools to automate the process of game library modeling. The script will enable the generation of multiple products from the single script, thus creating a system that lets designers /artists customize props and environments. The main goal is to measure the efficacy of the automated system generated to create a wide variety of game elements, further reducing the need for manual content creation and integrating it into the workflow of AAA and Indie Games. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iterative%20game%20design" title="iterative game design">iterative game design</a>, <a href="https://publications.waset.org/abstracts/search?q=generative%20design" title=" generative design"> generative design</a>, <a href="https://publications.waset.org/abstracts/search?q=gaming%20asset%20automation" title=" gaming asset automation"> gaming asset automation</a>, <a href="https://publications.waset.org/abstracts/search?q=generative%20game%20design" title=" generative game design"> generative game design</a> </p> <a href="https://publications.waset.org/abstracts/173936/revolutionizing-gaming-setup-design-utilizing-generative-and-iterative-methods-to-prop-and-environment-design-transforming-the-landscape-of-game-development-through-automation-and-innovation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173936.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">70</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">259</span> Transition Metal Carbodiimide vs. Spinel Matrices for Photocatalytic Water Oxidation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karla%20Lienau">Karla Lienau</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20M%C3%BCller"> Rafael Müller</a>, <a href="https://publications.waset.org/abstracts/search?q=Ren%C3%A9%20Mor%C3%A9"> René Moré</a>, <a href="https://publications.waset.org/abstracts/search?q=Debora%20Ressnig"> Debora Ressnig</a>, <a href="https://publications.waset.org/abstracts/search?q=Dan%20Cook"> Dan Cook</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Walton"> Richard Walton</a>, <a href="https://publications.waset.org/abstracts/search?q=Greta%20R.%20Patzke"> Greta R.

The four electron transfer process of water oxidation remains the bottleneck of water splitting, so that special emphasis is placed on the development of economic, stable and efficient water oxidation catalysts (WOCs). Our investigations introduced cobalt carbodiimide CoNCN and its transition metal analogues as WOC types, and further studies are focused on the interaction of different transition metals in the convenient all-nitrogen/carbon matrix. This provides further insights into the nature of the ‘true catalyst’ for cobalt centers in this non-oxide environment. Water oxidation activity is evaluated with complementary methods, namely photocatalytically using a Ru-dye sensitized standard setup as well as electrocatalytically, via immobilization of the WOCs on glassy carbon electrodes. To further explore the tuning potential of transition metal combinations, complementary investigations were carried out in oxidic spinel WOC matrices with more versatile host options than the carbodiimide framework. The influence of the preparative history on the WOC performance was evaluated with different synthetic methods (e.g. hydrothermally or microwave assisted). Moreover, the growth mechanism of nanoscale Co3O4-spinel as a benchmark WOC was investigated with in-situ PXRD techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbodiimide" title="carbodiimide">carbodiimide</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=spinels" title=" spinels"> spinels</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20oxidation" title=" water oxidation"> water oxidation</a> </p> <a href="https://publications.waset.org/abstracts/49987/transition-metal-carbodiimide-vs-spinel-matrices-for-photocatalytic-water-oxidation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49987.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">289</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">258</span> Participatory Air Quality Monitoring in African Cities: Empowering Communities, Enhancing Accountability, and Ensuring Sustainable Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wabinyai%20Fidel%20Raja">Wabinyai Fidel Raja</a>, <a href="https://publications.waset.org/abstracts/search?q=Gideon%20Lubisa"> Gideon Lubisa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Air pollution is becoming a growing concern in Africa due to rapid industrialization and urbanization, leading to implications for public health and the environment. Establishing a comprehensive air quality monitoring network is crucial to combat this issue. However, conventional methods of monitoring are insufficient in African cities due to the high cost of setup and maintenance. To address this, low-cost sensors (LCS) can be deployed in various urban areas through the use of participatory air quality network siting (PAQNS). PAQNS involves stakeholders from the community, local government, and private sector working together to determine the most appropriate locations for air quality monitoring stations. This approach improves the accuracy and representativeness of air quality monitoring data, engages and empowers community members, and reflects the actual exposure of the population. Implementing PAQNS in African cities can build trust, promote accountability, and increase transparency in the air quality management process. However, challenges to implementing this approach must be addressed. Nonetheless, improving air quality is essential for protecting public health and promoting a sustainable environment. Implementing participatory and data-informed air quality monitoring can take a significant step toward achieving these important goals in African cities and beyond. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low-cost%20sensors" title="low-cost sensors">low-cost sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=participatory%20air%20quality%20network%20siting" title=" participatory air quality network siting"> participatory air quality network siting</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20pollution" title=" air pollution"> air pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20quality%20management" title=" air quality management"> air quality management</a> </p> <a href="https://publications.waset.org/abstracts/170898/participatory-air-quality-monitoring-in-african-cities-empowering-communities-enhancing-accountability-and-ensuring-sustainable-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170898.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">257</span> Calibration of Syringe Pumps Using Interferometry and Optical Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Batista">E.

These instruments are critical in neonatology and oncology, where any variation in the flow rate and drug dosing quantity can lead to severe incidents and even death of the patient. Therefore it is very important to determine the accuracy and precision of these devices using the suitable calibration methods. The Volume Laboratory of the Portuguese Institute for Quality (LVC/IPQ) uses two different methods to calibrate syringe pumps from 16 nL/min up to 20 mL/min. The Interferometric method uses an interferometer to monitor the distance travelled by a pusher block of the syringe pump in order to determine the flow rate. Therefore, knowing the internal diameter of the syringe with very high precision, the travelled distance, and the time needed for that travelled distance, it was possible to calculate the flow rate of the fluid inside the syringe and its uncertainty. As an alternative to the gravimetric and the interferometric method, a methodology based on the application of optical technology was also developed to measure flow rates. Mainly this method relies on measuring the increase of volume of a drop over time. The objective of this work is to compare the results of the calibration of two syringe pumps using the different methodologies described above. The obtained results were consistent for the three methods used. The uncertainties values were very similar for all the three methods, being higher for the optical drop method due to setup limitations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calibration" title="calibration">calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=flow" title=" flow"> flow</a>, <a href="https://publications.waset.org/abstracts/search?q=interferometry" title=" interferometry"> interferometry</a>, <a href="https://publications.waset.org/abstracts/search?q=syringe%20pump" title=" syringe pump"> syringe pump</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/124348/calibration-of-syringe-pumps-using-interferometry-and-optical-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124348.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">109</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">256</span> Evaluation of Heterogeneity of Paint Coating on Metal Substrate Using Laser Infrared Thermography and Eddy Current</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Mezghani">S.

Infrared thermography is a nondestructive and non-invasive method that can be envisaged as a useful tool to measure the surface thickness variations by analyzing the temperature response. In this paper, the thermal quadrupole method for two layered samples heated up with a pulsed excitation is firstly used. By analyzing the thermal responses as a function of thermal properties and thicknesses of both layers, optimal parameters for the excitation source can be identified. Simulations show that a pulsed excitation with duration of ten milliseconds allows to obtain a substrate-independent thermal response. Based on this result, an experimental setup consisting of a near-infrared laser diode and an Infrared camera was next used to evaluate the variation of paint coating thickness between 60 µm and 130 µm on two samples. Results show that the parameters extracted for thermal images are correlated with the estimated thicknesses by the Eddy current methods. The laser pulsed thermography is thus an interesting alternative nondestructive method that can be moreover used for non conductive substrates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non%20destructive" title="non destructive">non destructive</a>, <a href="https://publications.waset.org/abstracts/search?q=paint%20coating" title=" paint coating"> paint coating</a>, <a href="https://publications.waset.org/abstracts/search?q=thickness" title=" thickness"> thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20thermography" title=" infrared thermography"> infrared thermography</a>, <a href="https://publications.waset.org/abstracts/search?q=laser" title=" laser"> laser</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a> </p> <a href="https://publications.waset.org/abstracts/20665/evaluation-of-heterogeneity-of-paint-coating-on-metal-substrate-using-laser-infrared-thermography-and-eddy-current" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20665.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">639</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">255</span> Measuring Engagement Equation in Educational Institutes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahfoodh%20Saleh%20Al%20Sabbagh">Mahfoodh Saleh Al Sabbagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Venkoba%20Rao"> Venkoba Rao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is plenty of research, both in academic and consultancy circles, about the importance and benefits of employee engagement and customer engagement and how it gives organization an opportunity to reduce variability and improve performance. Customer engagement is directly related to the engagement level of the organization's employees. It is therefore important to measure both. This research drawing from the work of Human Sigma by Fleming and Asplund, attempts to assess engagement level of customer and employees - the human systems of business - in an educational setup. Student is important to an educational institute and is a customer to be served efficiently and effectively. Considering student as customer and faculty as employees serving them, in–depth interviews were conducted to analyze the relationship between faculty and student engagement in two leading colleges in Oman, one from private sector and another from public sector. The study relied mainly on secondary data sources to understand the concept of engagement. However, the search of secondary sources was extensive to compensate the limited primary data. The results indicate that high faculty engagement is likely to lead to high student engagement. Engaged students were excited about learning, loved the feeling of they being cared as a person by their faculty and advocated the organization to other. The interaction truly represents an opportunity to build emotional connection to the organization. This study could be of interest to organizations interest in building and maintaining engagement with employees and customers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=customer%20engagement" title="customer engagement">customer engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20psychology" title=" consumer psychology"> consumer psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20institutes" title=" educational institutes"> educational institutes</a> </p> <a href="https://publications.waset.org/abstracts/17671/measuring-engagement-equation-in-educational-institutes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17671.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">472</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">254</span> Inductions of CaC₂ on Sperm Morphology and Viability of the Albino Mice (Mus musculus)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dike%20H.%20Ogbuagu">Dike H.

Thirty isogenic strains of male albino mice, Mus musculus (age≈ 8weeks; weight= 32.5±2.0g) were acclimatized (ambient temperature 28.0±1.0°C) for 2 weeks and fed standard growers mash and water ad libutum. They were later exposed to graded toxicant concentrations (w/w) of 2.5000, 1.2500, 0.6250, and 0.3125% in 4 cages. A control cage was also established. After 5 weeks, 3 animals from each cage were sacrificed by cervical dislocation and the cauda epididymis excised. Sperm morphology and viability were determined by microscopic procedures. The ANOVA, means plots, Student’s t-test and variation plots were used to analyze data. The common abnormalities observed included Double Head, Pin Head, Knobbed Head, No Tail and With Hook. The higher toxicant concentrations induced significantly lower body weights [F(829.899) ˃ Fcrit(4.19)] and more abnormalities [F(26.52) ˃ Fcrit(4.00)] at P˂0.05. Sperm cells in the control setup were significantly more viable than those in the 0.625% (t=0.005) and 2.500% toxicant doses (t=0.018) at the 95% confidence limit. CaC₂ appeared to induced morphological abnormalities and reduced viability in sperm cells of M. musculus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20ripening" title="artificial ripening">artificial ripening</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium%20carbide" title=" calcium carbide"> calcium carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20vendors" title=" fruit vendors"> fruit vendors</a>, <a href="https://publications.waset.org/abstracts/search?q=sperm%20morphology" title=" sperm morphology"> sperm morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=sperm%20viability" title=" sperm viability"> sperm viability</a> </p> <a href="https://publications.waset.org/abstracts/43338/inductions-of-cac2-on-sperm-morphology-and-viability-of-the-albino-mice-mus-musculus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43338.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">222</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">253</span> Absorbed Dose Measurements for Teletherapy Prediction of Superficial Dose Using Halcyon Linear Accelerator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Limen%20Njinga">Raymond Limen Njinga</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeneye%20Samuel%20Olaolu"> Adeneye Samuel Olaolu</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinyode%20Ojumoola%20Ajimo"> Akinyode Ojumoola Ajimo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Measurement of entrance dose and dose at different depths is essential to avoid overdose and underdose of patients. The aim of this study is to verify the variation in the absorbed dose using a water-equivalent material. Materials and Methods: The plastic phantom was arranged on the couch of the halcyon linear accelerator by Varian, with the farmer ionization chamber inserted and connected to the electrometer. The image of the setup was taken using the High-Quality Single 1280x1280x16 higher on the service mode to check the alignment with the isocenter. The beam quality TPR₂₀,₁₀ (Tissue phantom ratio) was done to check the beam quality of the machine at a field size of 10 cm x 10 cm. The calibration was done using SAD type set-up at a depth of 5 cm. This process was repeated for ten consecutive weeks, and the values were recorded. Results: The results of the beam output for the teletherapy machine were satisfactory and accepted in comparison with the commissioned measurement of 0.62. The beam quality TPR₂₀,₁₀ (Tissue phantom ratio) was reasonable with respect to the beam quality of the machine at a field size of 10 cm x 10 cm. Conclusion: The results of the beam quality and the absorbed dose rate showed a good consistency over the period of ten weeks with the commissioned measurement value. <p
