A LOS/NLOS likelihood hypothesis testing approach is applied based on exploiting distinctive statistical features of the channel impulse response (CIR) using parameters related to the “skewness” of the CIR and its root mean square (RMS) delay spread. A log-normal fit is presented for the probability densities of the CIR parameters. Simulation results show that different environments (residential, office, outdoor, etc.) have measurable differences in their CIR parameters’ statistics, which is then exploited in determining the nature of the propagation channels. Correct LOS/NLOS channel identification rates exceeding 90% are shown to be achievable for most types of environments. Additional improvement is also obtained by combining both CIR skewness and RMS delay statistics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UWB" title="UWB">UWB</a>, <a href="https://publications.waset.org/abstracts/search?q=propagation" title=" propagation"> propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=LOS" title=" LOS"> LOS</a>, <a href="https://publications.waset.org/abstracts/search?q=NLOS" title=" NLOS"> NLOS</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a> </p> <a href="https://publications.waset.org/abstracts/55684/reliable-line-of-sight-and-non-line-of-sight-propagation-channel-identification-in-ultra-wideband-wireless-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55684.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">249</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2755</span> Retrospection and Introspection on the Three-Decade Sight Translation Research in China—Bibliometric Analysis of CNKI (1987—2015) Relevant Articles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wei%20Deng">Wei Deng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on sorting and analyzing related literature on CNKI for nearly three decades between 1987—2015, this paper, adopting the method of bibliometrics, summarized and reviewed the domestic research on sight translation from three aspects. The analysis concluded the following findings: 1) The majority research had focused on the noumenon of sight translation. The rest of the three main research perspectives are in descending order: sight translation teaching, sight translation skills and other associated skills, and cognitive research of sight translation. 2) The domestic research increased significantly in recent five years, but there is much room for the quality. 3) The non-empirical study has had higher proportion, while the empirical study is unitary with the lack of triangle validation. This paper suggested that sight translation being in sore need of unified definition, multilingual, even interdisciplinary cooperation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bibliometric%20analysis" title="bibliometric analysis">bibliometric analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=perspectives" title=" perspectives"> perspectives</a>, <a href="https://publications.waset.org/abstracts/search?q=sight%20translation" title=" sight translation"> sight translation</a>, <a href="https://publications.waset.org/abstracts/search?q=tendency" title=" tendency"> tendency</a> </p> <a href="https://publications.waset.org/abstracts/51000/retrospection-and-introspection-on-the-three-decade-sight-translation-research-in-china-bibliometric-analysis-of-cnki-1987-2015-relevant-articles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51000.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">336</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">2754</span> Enhanced Bit Error Rate in Visible Light Communication: A New LED Hexagonal Array Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Matter">Karim Matter</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20Fayed"> Heba Fayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abd-Elaziz"> Ahmed Abd-Elaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Moustafa%20Hussein"> Moustafa Hussein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the exponential growth of mobile devices and wireless services, a huge demand for radiofrequency has increased. The presence of several frequencies causes interference between cells, which must be minimized to get the lower Bit Error Rate (BER). For this reason, it is of great interest to use visible light communication (VLC). This paper suggests a VLC system that decreases the BER by applying a new LED distribution with a hexagonal shape using a Frequency Reuse (FR) concept to mitigate the interference between the reused frequencies inside the hexagonal shape. The BER is measured in two scenarios, Line of Sight (LoS) and Non-Line of Sight (Non-LoS), for each technique that we used. The recommended values of BER in the proposed model for Soft Frequency Reuse (SFR) in the case of Los at 4, 8, and 10 dB signal to noise ratio (SNR), are 3.6×10⁻⁶, 6.03×10⁻¹³, and 2.66×10⁻¹⁸, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visible%20light%20communication%20%28VLC%29" title="visible light communication (VLC)">visible light communication (VLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20of%20view%20%28FoV%29" title=" field of view (FoV)"> field of view (FoV)</a>, <a href="https://publications.waset.org/abstracts/search?q=hexagonal%20array" title=" hexagonal array"> hexagonal array</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20reuse" title=" frequency reuse"> frequency reuse</a> </p> <a href="https://publications.waset.org/abstracts/146526/enhanced-bit-error-rate-in-visible-light-communication-a-new-led-hexagonal-array-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146526.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">160</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">2753</span> Gaze Patterns of Skilled and Unskilled Sight Readers Focusing on the Cognitive Processes Involved in Reading Key and Time Signatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20F.%20Viljoen">J. F.

They also have the ability to observe deviations from expected patterns in musical scores. This increases the “Eye-hand span” (reading ahead of the point of playing) in order to process the elements in the score. The study aims to investigate the gaze patterns of expert and non-expert sight readers focusing on key and time signatures. 20 musicians were tasked with playing 12 sight reading examples composed for one hand and five examples composed for two hands to be performed on a piano keyboard. These examples were composed in different keys and time signatures and included accidentals and changes of time signature to test this theory. Results showed that the experts fixate more and for longer on key and time signatures as well as deviations in examples for two hands than the non-expert group. The inverse was true for the examples for one hand, where expert sight readers showed fewer and shorter fixations on key and time signatures as well as deviations. This seems to suggest that experts focus more on the key and time signatures as well as deviations in complex scores to facilitate sight reading. The examples written for one appeared to be too easy for the expert sight readers, compromising gaze patterns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognition" title="cognition">cognition</a>, <a href="https://publications.waset.org/abstracts/search?q=eye%20tracking" title=" eye tracking"> eye tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=musical%20notation" title=" musical notation"> musical notation</a>, <a href="https://publications.waset.org/abstracts/search?q=sight%20reading" title=" sight reading"> sight reading</a> </p> <a href="https://publications.waset.org/abstracts/115499/gaze-patterns-of-skilled-and-unskilled-sight-readers-focusing-on-the-cognitive-processes-involved-in-reading-key-and-time-signatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115499.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">138</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">2752</span> Scalable Cloud-Based LEO Satellite Constellation Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Sobh">Karim Sobh</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20El-Ayat"> Khaled El-Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Fady%20Morcos"> Fady Morcos</a>, <a href="https://publications.waset.org/abstracts/search?q=Amr%20El-Kadi"> Amr El-Kadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Distributed applications deployed on LEO satellites and ground stations require substantial communication between different members in a constellation to overcome the earth coverage barriers imposed by GEOs. Applications running on LEO constellations suffer the earth line-of-sight blockage effect. They need adequate lab testing before launching to space. We propose a scalable cloud-based net-work simulation framework to simulate problems created by the earth line-of-sight blockage. The framework utilized cloud IaaS virtual machines to simulate LEO satellites and ground stations distributed software. A factorial ANOVA statistical analysis is conducted to measure simulator overhead on overall communication performance. The results showed a very low simulator communication overhead. Consequently, the simulation framework is proposed as a candidate for testing LEO constellations with distributed software in the lab before space launch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LEO" title="LEO">LEO</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=constellation" title=" constellation"> constellation</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite" title=" satellite"> satellite</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20simulation" title=" network simulation"> network simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=netfilter" title=" netfilter"> netfilter</a> </p> <a href="https://publications.waset.org/abstracts/23478/scalable-cloud-based-leo-satellite-constellation-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23478.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">386</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">2751</span> Optimized Text Summarization Model on Mobile Screens for Sight-Interpreters: An Empirical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianhua%20Wang">Jianhua Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To obtain key information quickly from long texts on small screens of mobile devices, sight-interpreters need to establish optimized summarization model for fast information retrieval.

The first algorithm uses only the measurements from one end of the line and the positive and zero sequence parameters of the line, while the second one uses the measurements from both ends of the line and only the positive sequence parameters of the line. The algorithms were tested using a transmission grid transposed in MATLAB. In a first stage it was established a fault location base line, where the algorithms mentioned above estimate the fault locations using the exact line parameters. After that, the positive and zero sequence resistance and reactance of the line were calculated again for different ground resistivity values and then the fault locations were estimated again in order to compare the results with the base line results.

Engineers and line managers usually do not recognize some of these factors and underutilize their production/assembly lines. In this paper, a special food processing assembly line is studied in detail, and procedures are presented to illustrate how productivity and efficiency of such lines can be increased. The assembly line considered produces ten different types of freshly prepared salads on the same line, which is called mixed model assembly line. Problems causing delays and inefficiencies on the line are identified. Line balancing and related tools are used to increase line efficiency and minimize balance delays. The procedure and the approach utilized in this paper can be useful for the operation managers and industrial engineers dealing with similar assembly lines in food processing industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20lines" title="assembly lines">assembly lines</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20balancing" title=" line balancing"> line balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20efficiency" title=" production efficiency"> production efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=bottleneck" title=" bottleneck"> bottleneck</a> </p> <a href="https://publications.waset.org/abstracts/68271/analysis-and-improvement-of-efficiency-for-food-processing-assembly-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68271.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">388</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">2747</span> Miniature Fast Steering Mirrors for Space Optical Communication on NanoSats and CubeSats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvain%20Chardon">Sylvain Chardon</a>, <a href="https://publications.waset.org/abstracts/search?q=Timot%C3%A9o%20Payre"> Timotéo Payre</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Grardel"> Hugo Grardel</a>, <a href="https://publications.waset.org/abstracts/search?q=Yann%20Quentel"> Yann Quentel</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Thomachot"> Mathieu Thomachot</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A9rald%20Aigouy"> Gérald Aigouy</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Claeyssen"> Frank Claeyssen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the increasing digitalization of society, access to data has become vital and strategic for individuals and nations. In this context, the number of satellite constellation projects is growing drastically worldwide and is a next-generation challenge of the New Space industry. So far, existing satellite constellations have been using radio frequencies (RF) for satellite-to-ground communications, inter-satellite communications, and feeder link communication. However, RF has several limitations, such as limited bandwidth and low protection level. To address these limitations, space optical communication will be the new trend, addressing both very high-speed and secured encrypted communication. Fast Steering Mirrors (FSM) are key components used in optical communication as well as space imagery and for a large field of functions such as Point Ahead Mechanisms (PAM), Raster Scanning, Beam Steering Mirrors (BSM), Fine Pointing Mechanisms (FPM) and Line of Sight stabilization (LOS). The main challenges of space FSM development for optical communication are to propose both a technology and a supply chain relevant for high quantities New Space approach, which requires secured connectivity for high-speed internet, Earth planet observation and monitoring, and mobility applications. CTEC proposes a mini-FSM technology offering a stroke of +/-6 mrad and a resonant frequency of 1700 Hz, with a mass of 50 gr. This FSM mechanism is a good candidate for giant constellations and all applications on board NanoSats and CubeSats, featuring a very high level of miniaturization and optimized for New Space high quantities cost efficiency. The use of piezo actuators offers a high resonance frequency for optimal control, with almost zero power consumption in step and stay pointing, and with very high-reliability figures > 0,995 demonstrated over years of recurrent manufacturing for Optronics applications at CTEC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20steering%20mirror" title="fast steering mirror">fast steering mirror</a>, <a href="https://publications.waset.org/abstracts/search?q=feeder%20link" title=" feeder link"> feeder link</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20of%20sight%20stabilization" title=" line of sight stabilization"> line of sight stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20communication" title=" optical communication"> optical communication</a>, <a href="https://publications.waset.org/abstracts/search?q=pointing%20ahead%20mechanism" title=" pointing ahead mechanism"> pointing ahead mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=raster%20scan" title=" raster scan"> raster scan</a> </p> <a href="https://publications.waset.org/abstracts/162023/miniature-fast-steering-mirrors-for-space-optical-communication-on-nanosats-and-cubesats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162023.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">80</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">2746</span> An Assembly Line Designing Study for a Refrigeration Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emin%20Gundogar">Emin Gundogar</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Erkayman"> Burak Erkayman</a>, <a href="https://publications.waset.org/abstracts/search?q=Aysegul%20Yilmaz"> Aysegul Yilmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusret%20Sazak"> Nusret Sazak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When considering current competition conditions on the world, satisfying customer demands on time has become an important factor that enables the firms take a step further.

In order to evaluate the extent to which the AD is a source of the broad Balmer lines and high ionization UV lines in radio-loud (RL) AGN, we focused on an extremely jetted RL quasar, 3C 47 that clearly shows a double peaked profile. This work presents its optical spectra and UV observations from the HST/FOS covering the rest-frame spectral range from 2000 to 7000 \AA. The fit of the low ionization lines, Hbeta, Halpha and MgII2800 show profiles that are in very good agreement with a relativistic Keplerian AD model. The profile of the prototypical high ionization lines can also be modeled by the contribution of the AD, with additional components due to outflows and emissions from the innermost part of the narrow line regions (NLRs). A prominent fit of the resulting double peaked profiles were found and very important disk parameters of the disk have been determined using the Hbeta, Halpha and MgII2800 lines: the inner and outer radii (both in units of G/mbh, where mbh is the supermassive black hole), an inclination to the line of sight, the emissivity index and the local broadening parameter. In addition, the accretion parameters, /mbh and /lledd are also determined. This work indicates that the line profile of 3C 47 shows the most convincing direct evidence for the presence of a rotating AD in AGN and the broad, double-peaked profiles originate from this AD that surrounds an /mbh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20galactic%20nuclei" title="active galactic nuclei">active galactic nuclei</a>, <a href="https://publications.waset.org/abstracts/search?q=quasars" title=" quasars"> quasars</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20lines" title=" emission lines"> emission lines</a>, <a href="https://publications.waset.org/abstracts/search?q=Double-peaked" title=" Double-peaked"> Double-peaked</a>, <a href="https://publications.waset.org/abstracts/search?q=supermassive%20black%20hole" title=" supermassive black hole"> supermassive black hole</a> </p> <a href="https://publications.waset.org/abstracts/175551/the-quasar-3c-47extreme-population-b-jetted-source-with-double-peaked-profile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175551.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">75</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">2744</span> A Preliminary Development of Virtual Sight-Seeing Website for Thai Temples on Rattanakosin Island </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pijitra%20Jomsri">Pijitra Jomsri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, the sources of cultures and tourist attractions are presented in online documentary form only.

So the impedance, admittance voltage and current along the line are expanded as a Taylor series in x/l where l is the total length of the line to obtain at the end, the main transmission line parameters such as voltage response and transmission and reflexion coefficients represented by scattering parameters in frequency domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABCD%20parameters" title="ABCD parameters">ABCD parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=characteristic%20impedance%20exponential%20nonuniform%20transmission%20line" title=" characteristic impedance exponential nonuniform transmission line"> characteristic impedance exponential nonuniform transmission line</a>, <a href="https://publications.waset.org/abstracts/search?q=Picard-Carson%27s%20method" title=" Picard-Carson's method"> Picard-Carson's method</a>, <a href="https://publications.waset.org/abstracts/search?q=S%20parameters" title=" S parameters"> S parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylor%27s%20series" title=" Taylor's series"> Taylor's series</a> </p> <a href="https://publications.waset.org/abstracts/32383/analysis-of-exponential-nonuniform-transmission-line-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32383.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">443</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">2741</span> Enhancement of the Performance of Al-Qatraneh 33-kV Transmission Line Using STATCOM: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hamad">Ali Hamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Al-Drous"> Ibrahim Al-Drous</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleh%20Al-Jufout"> Saleh Al-Jufout</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a case study of using STATCOM to enhance the performance of Al-Qatraneh 33-kV transmission line.

It is usually caused by a retrobulbar hemorrhage as a result of trauma. If not treated in a timely manner, permanent vision loss can occur. Lateral canthotomy and cantholysis are minor procedures that can be performed bedside with equipment available in the emergency department. The aim of the procedure is to release the attachments between the suspensory ligaments of the eye and the bony orbital wall, leading to a decrease in intraorbital pressure and preventing irreversible loss of vision. As most Ophthalmologists across the UK provide non-resident on-call service, this may lead to a delay in the treatment of OCS and stresses the need for Emergency medical staff to be able to provide this sight-saving procedure independently. Aim: To survey current training, experience, and confidence levels among Emergency Medicine doctors in performing emergency lateral canthotomy and to establish whether these variables change the following teaching from experienced ophthalmologists. RESULTS: Most EM registrars had little to no experience in performing lateral canthotomy and cantholysis. The majority of them showed a significant increase in their confidence to perform the procedure following ophthalmic-led teaching. The survey also showed that the registrars felt such training should be added to/part of the EM curriculum. Conclusion: The involvement of Ophthalmologists in the teaching of EM doctors to recognise and treat OCS independently may prevent delays in treatment and reduce the risk of permanent sight loss. This project showed potential in improving patient care and will lead to a National Survey of EM doctors across the UK. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lateral%20canthotomy" title="lateral canthotomy">lateral canthotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=retrobulbar%20hemorrhage" title=" retrobulbar hemorrhage"> retrobulbar hemorrhage</a>, <a href="https://publications.waset.org/abstracts/search?q=Ophthalmology" title=" Ophthalmology"> Ophthalmology</a>, <a href="https://publications.waset.org/abstracts/search?q=orbital%20compartment%20syndrome" title=" orbital compartment syndrome"> orbital compartment syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=sight%20loss" title=" sight loss"> sight loss</a>, <a href="https://publications.waset.org/abstracts/search?q=blindness" title=" blindness"> blindness</a> </p> <a href="https://publications.waset.org/abstracts/161386/confidence-levels-among-uk-emergency-medicine-doctors-in-performing-emergency-lateral-canthotomy-should-it-be-a-key-skill-in-the-ed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161386.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">98</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">2738</span> Principal Component Analysis Applied to the Electric Power Systems – Practical Guide; Practical Guide for Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Morales">John Morales</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Ordu%C3%B1a"> Eduardo Orduña</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently the Principal Component Analysis (PCA) theory has been used to develop algorithms regarding to Electric Power Systems (EPS).

This paper examines the balancing effect of a whole production line of a real auto glass manufacturer in three steps. In the first step, processing time of each activity in the workstations is generated according to a practical approach. In the second step, the whole production process is simulated and the bottleneck stations have been identified, and finally in the third step, several improvement scenarios are generated to optimize the system throughput, and the best one is proposed. The main contribution of the current research is the proposed framework which combines two famous approaches including Assembly Line Balancing and Optimization via Simulation technique (OvS). The results show that the proposed framework could be applied in practical environments, easily. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20line%20balancing%20problem" title="assembly line balancing problem">assembly line balancing problem</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20via%20simulation" title=" optimization via simulation"> optimization via simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning" title=" production planning"> production planning</a> </p> <a href="https://publications.waset.org/abstracts/24107/a-new-ovs-approach-in-assembly-line-balancing-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24107.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">526</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">2732</span> Building a Measure of Sensory Preferences For (Wrestling and Boxing) Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Nabhan">Mohamed Nabhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research aims to build a measure of sensory preferences for (wrestling and boxing) players.

The customization level of a product is defined by the fraction of aesthetic attributes of the product that the manufacturer chooses to customize. In contrast to the existing literature on product line design that predominantly assumes deterministic demand, we consider the presence of demand uncertainty and frame the product line design problem in a single period (news vendor) setting. We examine the effect of demand uncertainty on product line decisions. Furthermore, we also examine how product line decisions are influenced by channel structure. While we use the centralized channel as a benchmark, we consider the decentralized dual channel where the customized product is sold through an online channel owned by the manufacturer and the standard product is sold through a retailer. We introduce a supply contract between the manufacturer and the retailer for improving channel efficiency and coordinate the distribution channel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=product%20line%20design" title="product line design">product line design</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20uncertainty" title=" demand uncertainty"> demand uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=customization%20level" title=" customization level"> customization level</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20channel" title=" distribution channel"> distribution channel</a> </p> <a href="https://publications.waset.org/abstracts/83258/product-line-design-with-customization-in-the-presence-of-demand-uncertainty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83258.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">186</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">2728</span> Transforming Butterworth Low Pass Filter into Microstrip Line Form at LC-Band Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liew%20Hui%20Fang">Liew Hui Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Idris%20Syed%20Hassan"> Syed Idris Syed Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Fareq%20Abd.%20Malek"> Mohd Fareq Abd.

The filter’s lumped element circuits and microstrip line form were first designed and simulated using Advanced Design Software (ADS) to obtain the best filter characteristic based on S-parameter and implemented on FR4 substrate for order N=3,4,5,6,7,8 and 9. The importance of a new approach of transforming method as a correction factor has been considered into designed microstrip line. From ADS simulation results proved that the response of microstrip line circuit of Butterworth low pass filter with fringing correction factor has an excellent agreement with its lumped circuit.
