So far, different types of empirical equations for estimation of the coefficient have been developed, based on various case studies. The main objective of this paper is to develop an empirical equation for estimation of the coefficient for a riverine flow. For this purpose, a set of tracer experiments was conducted, involving salt tracer, at three sections located in downstream of a lengthy canal. Tracer data were measured in three mixing lengths along the canal including; 45, 75 and 100m. According to the results, the obtained coefficients from new developed empirical equation gave an encouraging level of agreement with the theoretical values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coef%EF%AC%81cients" title="coefﬁcients">coefﬁcients</a>, <a href="https://publications.waset.org/abstracts/search?q=dispersion" title=" dispersion"> dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=river" title=" river"> river</a>, <a href="https://publications.waset.org/abstracts/search?q=tracer" title=" tracer"> tracer</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/31418/estimation-of-longitudinal-dispersion-coefficient-using-tracer-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31418.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">389</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">62</span> Islam’s Expediency; The Poison and the Antidote of Islamic Government</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Ebrahimi">Mahdi Ebrahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most effective factors that can empower and modernize the Islamic government according to the needs of society is the institution of expediency in Islamic governance. At the same time, not paying attention to the foundations and principles of Islamic governance may cause this factor to create the basis for corruption and totalitarianism of the rulers, which ultimately causes a gap between the people and the rulers and the emergence of whole government corruption and dictatorship. Meanwhile, there are specific principles in the doctrine of Islamic Governance that can prevent such an event from happening. Principles such as: remaining popular and pious by the Ulama, Amr Bil-Maroof Va Nahy An Al-Munkar (commanding the good and preventing the bad) by the individuals, the rule of frank criticism with loud voices and clarification and accountability in the fields that cause the corruption of those in charge. In this research, these principles are presented along with their Islamic basis.

The results show that climate variability significantly affected surface water quality over the time. The existence of yearly internal variation and hysteresis phenomenon for pH and EC parameters was observed.

FPGA is an integrated circuit that contains an array of logic blocks, and its architecture can be reprogrammed and reconfigured after manufacturing. Complex circuits for various applications can be designed and implemented using FPGA hardware. The reconfigurable hardware used in this paper is an SoC (System on a Chip) FPGA type that integrates both microprocessor and FPGA architectures into a single device. In the present study the Laplace equation is implemented and solved numerically on both reconfigurable hardware and CPU. The precision of results and speedups of the calculations are compared together. The computational process on FPGA, is up to 20 times faster than a conventional CPU, with the same data precision.

Because photovoltaic generates power in low voltage, first, generated power should increase. Usually, distributed generation injects their power to AC-Grid, hence after voltage increasing an inverter is needed to convert DC power to AC power. This results in utilization two series converter that grows cost, complexity, and low efficiency. In this paper a single stage inverter is utilized to boost and invert in one stage. Control of this scheme is easier, and its initial cost decreases comparing to conventional double stage inverters. A simple control scheme is used to control active power as well as minimum total harmonic distortion (THD) in injected current. Simulations in MATLAB demonstrate better outputs comparing with conventional approaches. <p class="card-text"><strong>Keywords:</strong> <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=boost%20inverter" title=" boost inverter"> boost inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20strategy" title=" control strategy"> control strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20phase%20inverter" title=" three phase inverter"> three phase inverter</a> </p> <a href="https://publications.waset.org/abstracts/47543/control-scheme-for-single-stage-boost-inverter-for-grid-connected-photovoltaic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47543.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">372</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">56</span> Predicting Shot Making in Basketball Learnt Fromadversarial Multiagent Trajectories</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Harmon">Mark Harmon</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolghani%20Ebrahimi"> Abdolghani Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Lucey"> Patrick Lucey</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Klabjan"> Diego Klabjan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we predict the likelihood of a player making a shot in basketball from multiagent trajectories. Previous approaches to similar problems center on hand-crafting features to capture domain-specific knowledge. Although intuitive, recent work in deep learning has shown, this approach is prone to missing important predictive features. To circumvent this issue, we present a convolutional neural network (CNN) approach where we initially represent the multiagent behavior as an image. To encode the adversarial nature of basketball, we use a multichannel image which we then feed into a CNN. Additionally, to capture the temporal aspect of the trajectories, we use “fading.” We find that this approach is superior to a traditional FFN model. By using gradient ascent, we were able to discover what the CNN filters look for during training. Last, we find that a combined FFN+CNN is the best performing network with an error rate of 39%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basketball" title="basketball">basketball</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20network" title=" convolutional neural network"> convolutional neural network</a> </p> <a href="https://publications.waset.org/abstracts/133743/predicting-shot-making-in-basketball-learnt-fromadversarial-multiagent-trajectories" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133743.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">153</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">55</span> A Practical Protection Method for Parallel Transmission-Lines Based on the Fault Travelling-Waves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Ebrahimi">Mohammad Reza Ebrahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In new restructured power systems, swift fault detection is very important. The parallel transmission-lines are vastly used in this kind of power systems because of high amount of energy transferring. In this paper, a method based on the comparison of two schemes, i.e., i) maximum magnitude of travelling-wave (TW) energy ii) the instants of maximum energy occurrence at the circuits of parallel transmission-line is proposed. Using the travelling-wave of fault in order to faulted line identification this method has noticeable operation time. Moreover, the algorithm can cover for identification of faults as external or internal faults. For an internal fault, the exact location of the fault can be estimated confidently.

The surge in the hospital services demand beyond the current capacity leads to shortage of ICU beds and ventilators in some parts of US. In this study, we forecast the required number of hospital beds and possible shortage of beds in US during COVID-19 pandemic to be used in the planning and hospitalization of new cases. In this paper, we used a data on COVID-19 deaths and patients’ hospitalization besides the data on hospital capacities and utilization in US from publicly available sources and national government websites. we used a novel ensemble modelling of deep learning networks, based on stacking different linear and non-linear layers to predict the shortage in hospital beds.

The methodology allows for considering numerous design variables with different natures concurrently. It redefines the ultimate goal of design based on the notion of satisfaction, resulting in the simplification of the multi-objective constrained optimization process. It also formalizes the effect of designer’s subjective attitude in the process. To enhance modeling efficiency for both computation and accuracy, a hardware-in-the-loop simulation platform is used, which involves physical joint modules and the control unit in addition to the software modules. This platform is implemented in the HCD design architecture to reliably evaluate the design attributes and performance super criterion during the design process. The resulting overall architecture is applied to redesigning kinematic, dynamic and control parameters of an industrial robot manipulator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concurrent%20engineering" title="concurrent engineering">concurrent engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=hardware-in-the-loop%20simulation" title=" hardware-in-the-loop simulation"> hardware-in-the-loop simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20manipulator" title=" robot manipulator"> robot manipulator</a>, <a href="https://publications.waset.org/abstracts/search?q=multidisciplinary%20systems" title=" multidisciplinary systems"> multidisciplinary systems</a>, <a href="https://publications.waset.org/abstracts/search?q=mechatronics" title=" mechatronics"> mechatronics</a> </p> <a href="https://publications.waset.org/abstracts/2865/advanced-mechatronic-design-of-robot-manipulator-using-hardware-in-the-loop-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2865.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">454</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">50</span> Effect of Lemongrass Oil Containing Polycaprolactone Nanofibers on Biofilm Formation of Proteus mirabilis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulcan%20Sahal">Gulcan Sahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Nasseri"> Behzad Nasseri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Akbar%20Ebrahimi"> Ali Akbar Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Isil%20Seyis%20Bilkay"> Isil Seyis Bilkay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Proteus mirabilis strains which are natural colonizers of healthy individuals’ gastrointestinal tract are also known as common causes of catheter-associated urinary tract infections. Nowadays, as a result of an increased resistance to various antimicrobial drugs, there has been a growing interest in natural products. Therefore, the aim of this study is to investigate biofilm formation of P. mirabilis strains on lemongrass oil containing polycaprolactone nanofibers. Polycaprolactone nanofibers with different lemongrass oil concentrations were successfully prepared by electrospinning and biofilm formation of P. mirabilis on these nanofibers were determined by ‘Crystal Violet Staining Assay’. According to our results, polycaprolactone nanofibers with some lemongrass oil concentrations, decreased biofilm formation of P. mirabilis and this effect increased in parallel with the increase in lemongrass oil concentration. Our results indicate that, polycaprolactone nanofibers with some concentrations of lemongrass oil may provide a treatment against catheter-associated urinary tract infections by means of causing an inhibition on biofilm formation of P. mirabilis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-biofilm" title="anti-biofilm">anti-biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm%20formation" title=" biofilm formation"> biofilm formation</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=proteus%20mirabilis" title=" proteus mirabilis"> proteus mirabilis</a> </p> <a href="https://publications.waset.org/abstracts/55250/effect-of-lemongrass-oil-containing-polycaprolactone-nanofibers-on-biofilm-formation-of-proteus-mirabilis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55250.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">412</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Intrusion Detection System Based on Peer to Peer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Pour%20Ebrahimi">Alireza Pour Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Abasi"> Vahid Abasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently by the extension of internet usage, Research on the intrusion detection system takes a significant importance. Many of improvement systems prevent internal and external network attacks by providing security through firewalls and antivirus. In recently years, intrusion detection systems gradually turn from host-based systems and depend on O.S to the distributed systems which are running on multiple O.S. In this work, by considering the diversity of computer networks whit respect to structure, architecture, resource, services, users and also security goals requirement a fully distributed collaborative intrusion detection system based on peer to peer architecture is suggested. in this platform each partner device (matched device) considered as a peer-to-peer network. All transmitted information to network are visible only for device that use security scanning of a source.

These networks generally have a simple protection system usually implemented using fuses, re-closers, and over-current relays. Recently, great attention has been paid to applying Distributed energy resources (DERs) throughout electric distribution systems. Presence of such generation in a network leads to losing coordination of protection devices. Therefore, it is desired to develop an algorithm which is capable of protecting distribution systems that include DER. On the other hand smart grid brings opportunities to the power system. Fast advancement in communication and measurement techniques accelerates the development of multi agent system (MAS). So in this paper, a new approach for the protection of distribution networks in the presence of DERs is presented base on MAS. The proposed scheme has been implemented on a sample 27-bus distribution network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20energy%20resource" title="distributed energy resource">distributed energy resource</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20network" title=" distribution network"> distribution network</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20agent%20system" title=" multi agent system"> multi agent system</a> </p> <a href="https://publications.waset.org/abstracts/33470/a-multi-agent-based-protection-scheme-for-smart-distribution-network-in-presence-of-distributed-energy-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33470.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">608</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">47</span> Effect of Humidity on In-Process Crystallization of Lactose During Spray Drying</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amirali%20Ebrahimi">Amirali Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20A.%20G.%20Langrish"> T.

It has been suggested by Williams–Landel–Ferry kinetics (WLF) that a higher particle temperature and lower glass-transition temperature would increase the crystallization rate of the particles during the spray-drying process. Freshly humidified air produced by a Buchi-B290 spray dryer as a humidifier attached to the main spray dryer decreased the particle glass-transition temperature (Tg), while allowing the particle temperature (Tp) to reach higher values by using an insulated drying chamber. Differential scanning calorimetry (DSC) and moisture sorption analysis were used to measure the degree of crystallinity for the spray-dried lactose powders. The results showed that higher Tp-Tg, as a result of applying humid air, improved the process yield from 21 ± 4 to 26 ± 2% and crystallinity of the particles by decreasing the latent heat of crystallization from 43 ± 1 to 30 ± 11 J/g and the sorption peak height from 7.3 ± 0.7% to 6 ± 0.7%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lactose" title="lactose">lactose</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20drying" title=" spray drying"> spray drying</a>, <a href="https://publications.waset.org/abstracts/search?q=humid%20air" title=" humid air"> humid air</a> </p> <a href="https://publications.waset.org/abstracts/7244/effect-of-humidity-on-in-process-crystallization-of-lactose-during-spray-drying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7244.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">425</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">46</span> A Robust Optimization Method for Service Quality Improvement in Health Care Systems under Budget Uncertainty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Ashrafi">H.

In order to improve service quality of a clinic, four important dimensions are defined: tangibles, responsiveness, empathy, and reliability. Moreover, there are several service stages in hospitals such as financial screening and examination. One of the most challenging limitations for improving service quality is budget which impressively affects the service quality. In this paper, we present an approach to address budget uncertainty and provide guidelines for service resource allocation. In this paper, a service quality improvement approach is proposed which can be adopted to multistage service processes to improve service quality, while controlling the costs. A multi-objective function based on the importance of each area and dimension is defined to link operational variables to service quality dimensions. The results demonstrate that our approach is not ultra-conservative and it shows the actual condition very well. Moreover, it is shown that different strategies can affect the number of employees in different stages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allocation" title="allocation">allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=budget%20uncertainty" title=" budget uncertainty"> budget uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20resource" title=" healthcare resource"> healthcare resource</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20quality%20assessment" title=" service quality assessment"> service quality assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20optimization" title=" robust optimization "> robust optimization </a> </p> <a href="https://publications.waset.org/abstracts/124177/a-robust-optimization-method-for-service-quality-improvement-in-health-care-systems-under-budget-uncertainty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124177.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">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Conceptualizing IoT Based Framework for Enhancing Environmental Accounting By ERP Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Ebrahimi%20Ghadi">Amin Ebrahimi Ghadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Moalagh"> Morteza Moalagh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research is carried out to find how a perfect combination of IoT architecture (Internet of Things) and ERP system can strengthen environmental accounting to incorporate both economic and environmental information.

The aim of this study was to investigate the effect of long term HD on memory types of HD patients. To assess the different type of memory, we used memory parts of the Persian Papers and Pencil Cognitive assessment package (PCAP) and Addenbrooke's Cognitive Examination (ACE-R). Our study included 80 HD patients of whom 39 had less than six months of HD and 41 patients and another group which had a history of HD more than six months. The population had a mean age of 51.60 years old and 27.5% of them were female. The scores of patients who have been hemodialyzed for a long time (median time of HD was up to 4 years) had lower score in anterograde, explicit, visual, recall and recognition memory (5.44±1.07, 9.49±3.472, 22.805±6.6913, 5.59±10.435, 11.02±3.190 score) than the HD patients who underwent HD for a shorter term, where the median time was 3 to 5 months (P<0.01). The regression result shows that, by increasing the HD duration, all memory types are reduced (R2=0.600, P<0.01). The present study demonstrated that HD patients who were under HD for a long time had significantly lower scores in the different types of memory. However, additional researches are needed in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hemodialysis%20patients" title="hemodialysis patients">hemodialysis patients</a>, <a href="https://publications.waset.org/abstracts/search?q=duration%20of%20hemodialysis" title=" duration of hemodialysis"> duration of hemodialysis</a>, <a href="https://publications.waset.org/abstracts/search?q=memory%20types" title=" memory types"> memory types</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahedan" title=" Zahedan"> Zahedan</a> </p> <a href="https://publications.waset.org/abstracts/83159/memory-types-in-hemodialysis-patients-a-study-based-on-hemodialysis-duration-zahedan-south-east-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83159.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">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Ceramic Membrane Filtration Technologies for Oilfield Produced Water Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Ebrahimi">Mehrdad Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Schmitz"> Oliver Schmitz</a>, <a href="https://publications.waset.org/abstracts/search?q=Axel%20Schmidt"> Axel Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Czermak"> Peter Czermak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> “Produced water” (PW) is any fossil water that is brought to the surface along with crude oil or natural gas. By far, PW is the largest waste stream by volume associated with oil and gas production operations. Due to the increasing volume of waste all over the world in the current decade, the outcome and effect of discharging PW on the environment has lately become a significant issue of environmental concerns. Therefore, there is a need for new technologies for PW treatment due to increase focus on water conservation and environmental regulation. The use of membrane processes for treatment of PW has several advantages over many of the traditional separation techniques. In oilfield produced water treatment with ceramic membranes, process efficiency is characterized by the specific permeate flux and by the oil separation performance. Apart from the membrane properties, the permeate flux during filtration of oily wastewaters is known to be strongly dependent on the constituents of the feed solution, as well as on process conditions, e.g. trans-membrane pressure (TMP) and cross-flow velocity (CFV). The research project presented in these report describes the application of different ceramic membrane filtration technologies for the efficient treatment of oil-field produced water and different model oily solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20membrane" title="ceramic membrane">ceramic membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20fouling" title=" membrane fouling"> membrane fouling</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20rejection" title=" oil rejection"> oil rejection</a>, <a href="https://publications.waset.org/abstracts/search?q=produced%20water%20treatment" title=" produced water treatment"> produced water treatment</a> </p> <a href="https://publications.waset.org/abstracts/121611/ceramic-membrane-filtration-technologies-for-oilfield-produced-water-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121611.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">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Experimental and Analytical Dose Assessment of Patient's Family Members Treated with I-131</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marzieh%20Ebrahimi">Marzieh Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Changizi"> Vahid Changizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Kardan"> Mohammad Reza Kardan</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mahdi%20Hosseini%20Pooya"> Seyed Mahdi Hosseini Pooya</a>, <a href="https://publications.waset.org/abstracts/search?q=Parham%20Geramifar"> Parham Geramifar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radiation exposure to the patient's family members is one of the major concerns during thyroid cancer radionuclide therapy.

Eighty-five adult family members of fifty-one patients volunteered to participate in this research study. Considering the minimum and maximum range of dose rate from 15 µsv/h to 120 µsv/h at patients' release time, the calculated mean and median dose values of family members were 0.45 mSv and 0.28 mSv, respectively. Moreover, almost all family members’ doses were measured to be less than the dose constraint of 5 mSv recommended by Basic Safety Standards. Considering the influence parameters such as patient dose rate and administrated activity, the total effective doses of family members were calculated by TEDE and NRC formulas and compared with those of experimental results. The results indicated that, it is fruitful to use the quantitative calculations for releasing patients treated with I-131 and correct estimation of patients' family doses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effective%20dose" title="effective dose">effective dose</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoluminescence" title=" thermoluminescence"> thermoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=I-131" title=" I-131"> I-131</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid%20cancer" title=" thyroid cancer"> thyroid cancer</a> </p> <a href="https://publications.waset.org/abstracts/50786/experimental-and-analytical-dose-assessment-of-patients-family-members-treated-with-i-131" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50786.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">399</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Analysis of the Sagittarius, Borje Ghos, the Symbol of the City of Isfahan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shirin%20Manavi">Shirin Manavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gorbanali%20Ebrahimi"> Gorbanali Ebrahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Man is a symbolist. He experiences living, whether he lived in the Old World or he is living in today's world. The symbol is a kind of concise expression of wishes and in the meantime, it comprises all the demands and Dos and Don'ts of a group, a people, and a nation. Our land, Iran, is also the land of symbols, explicit and hidden ones. The astronomical symbols are among these symbols that were recruited in fortune telling of cities. One of the symbols is the astronomical symbol of sagittairc which is the astrology of some cities such as Isfahan. November 22 of each year has been selected by Isfahan experts as Isfahan's Glorification Day. They have also selected the historically painted picture on the entrance of Qeysariye Bazar which has been designed based on the arch constellation. This symbol was chosen because Isfahan has been found in arch constellation on the basis of historical documentation of astrology. This study aims at the recognition, description, and analysis of the arch constellation, the symbol of Isfahan where it has been displayed once upon a time over the Tabarak castle and it is for centuries on the vertex of Isfahan's Qeysariye Bazar. This research has been done on the basis of the analytical method, but due to the particular structure of this paper, it has also benefited from the historical and descriptive methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isfahan%27s%20Qeysariye%20Bazar" title="Isfahan's Qeysariye Bazar">Isfahan's Qeysariye Bazar</a>, <a href="https://publications.waset.org/abstracts/search?q=semiotics" title=" semiotics"> semiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=astrology%20of%20cities" title=" astrology of cities"> astrology of cities</a>, <a href="https://publications.waset.org/abstracts/search?q=constellation" title=" constellation"> constellation</a>, <a href="https://publications.waset.org/abstracts/search?q=sagittairc%20%28Borje%20Ghos%29" title=" sagittairc (Borje Ghos)"> sagittairc (Borje Ghos)</a> </p> <a href="https://publications.waset.org/abstracts/47743/analysis-of-the-sagittarius-borje-ghos-the-symbol-of-the-city-of-isfahan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47743.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">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Effects of Oral Resveratrol Supplementation on Inflammation and Quality of Life in Patients with Ulcerative Colitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Samsami">M.

Resveratrol is an antioxidant and anti-inflammatory compound. This study determined the effects of resveratrol compound on inflammatory factors in patients with ulcerative colitis. This study was a double-blind randomized clinical trial conducted on 50 patients with UC. Subjects received one capsule daily for 6 wk of either resveratrol (500 mg) or a placebo. Inflammatory factors, anthropometric measures, and IBDQ-9 (Inflammatory Bowel Disease Questionnaire-9) scores were assessed at baseline and at the end of the study. STATA12 software was used for data analysis. No significant differences were found in the background variables between the two groups at baseline. The results indicated that resveratrol supplementation for 6 week significantly decreased plasma levels of TNF-a and hs-CRP and the activity of NF-κB over the placebo group (p<0.001). Significant differences remained after adjustment for vitamin C (p<0.0001). The IBDQ-9 scores increased significantly in the resveratrol group over the placebo group (p<0.001).

Paclitaxel (PTX) and dipalmitoylphosphatidylcholine (DPPC) were selected for the drug molecule and as a natural phospholipid nanocarrier, respectively. This work focused on two important interaction parameters between molecules in terms of center of mass (COM) and van der Waals interaction energy. Furthermore, we compared the simulation results of the PTX interaction with the cell membrane and the interaction of DPPC as a nanocarrier loaded by the drug with the cell membrane. The molecular dynamic analysis resulted in low energy between the nanocarrier and the cell membrane as well as significant decrease of COM amount in the nanocarrier and the cell membrane system during the interaction. Thus, the drug vehicle showed notably better interaction with the cell membrane in compared to free drug interaction with the cell membrane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-cancer%20drug" title="anti-cancer drug">anti-cancer drug</a>, <a href="https://publications.waset.org/abstracts/search?q=center%20of%20mass" title=" center of mass"> center of mass</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20energy" title=" interaction energy"> interaction energy</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocarrier" title=" nanocarrier"> nanocarrier</a> </p> <a href="https://publications.waset.org/abstracts/73548/assessment-of-drug-delivery-systems-from-molecular-dynamic-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73548.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">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> An Ensemble Deep Learning Architecture for Imbalanced Classification of Thoracic Surgery Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saba%20%20Ebrahimi">Saba Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ahmadian"> Saeed Ahmadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hedie%20%20Ashrafi"> Hedie Ashrafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Selecting appropriate patients for surgery is one of the main issues in thoracic surgery (TS). Both short-term and long-term risks and benefits of surgery must be considered in the patient selection criteria. There are some limitations in the existing datasets of TS patients because of missing values of attributes and imbalanced distribution of survival classes. In this study, a novel ensemble architecture of deep learning networks is proposed based on stacking different linear and non-linear layers to deal with imbalance datasets. The categorical and numerical features are split using different layers with ability to shrink the unnecessary features. Then, after extracting the insight from the raw features, a novel biased-kernel layer is applied to reinforce the gradient of the minority class and cause the network to be trained better comparing the current methods. Finally, the performance and advantages of our proposed model over the existing models are examined for predicting patient survival after thoracic surgery using a real-life clinical data for lung cancer patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a
