This type of equipment, combined with pre-established medical protocols, contributes significantly to the containment of highly transmissible pathogens such as COVID-19. Due to its hermetic isolation, it allows more excellent patient safety, protecting companions and the health team. In this context, this work presents the development, testing, and validation of a medical capsule to treat patients affected by COVID-19. To this end, requirements such as low cost and easy handling were considered to meet the demand of people infected with the virus in remote locations in the Amazon region and/or where there are no ICU beds and mechanical ventilators for orotracheal intubation. Conceived and developed in a partnership between SAMEL Planos de Saúde and Instituto Conecthus, the device entitled "Vanessa Capsule" was designed to be used together with the NIV protocol (non-invasive ventilation), has an automatic exhaust system and filters performing the CO2 exchange, in addition to having BiPaps ventilatory support equipment (mechanical fans) in the Cabin Kit. The results show that the degree of effectiveness in protecting against infection by aerosols, with the protection cabin, is satisfactory, implying the consideration of the Vanessa capsule as an auxiliary method to be evaluated by the health team. It should also be noted that the medical observation of the evaluated patients found that the treatment against the COVID-19 virus started earlier with non-invasive mechanical ventilation reduces the patient's suffering and contributes positively to their recovery, in association with isolation through the Vanessa capsule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20ventilators" title=" mechanical ventilators"> mechanical ventilators</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20capsule" title=" medical capsule"> medical capsule</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20ventilation" title=" non-invasive ventilation"> non-invasive ventilation</a> </p> <a href="https://publications.waset.org/abstracts/163906/development-of-an-aerosol-protection-capsule-for-patients-with-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163906.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1865</span> Detection of COVID-19 Cases From X-Ray Images Using Capsule-Based Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Donya%20Ashtiani%20Haghighi">Donya Ashtiani Haghighi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirali%20Baniasadi"> Amirali Baniasadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coronavirus (COVID-19) disease has spread abruptly all over the world since the end of 2019. Computed tomography (CT) scans and X-ray images are used to detect this disease. Different Deep Neural Network (DNN)-based diagnosis solutions have been developed, mainly based on Convolutional Neural Networks (CNNs), to accelerate the identification of COVID-19 cases. However, CNNs lose important information in intermediate layers and require large datasets. In this paper, Capsule Network (CapsNet) is used. Capsule Network performs better than CNNs for small datasets. Accuracy of 0.9885, f1-score of 0.9883, precision of 0.9859, recall of 0.9908, and Area Under the Curve (AUC) of 0.9948 are achieved on the Capsule-based framework with hyperparameter tuning. Moreover, different dropout rates are investigated to decrease overfitting. Accordingly, a dropout rate of 0.1 shows the best results. Finally, we remove one convolution layer and decrease the number of trainable parameters to 146,752, which is a promising result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capsule%20network" title="capsule network">capsule network</a>, <a href="https://publications.waset.org/abstracts/search?q=dropout" title=" dropout"> dropout</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperparameter%20tuning" title=" hyperparameter tuning"> hyperparameter tuning</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a> </p> <a href="https://publications.waset.org/abstracts/164276/detection-of-covid-19-cases-from-x-ray-images-using-capsule-based-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164276.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1864</span> Detecting Manipulated Media Using Deep Capsule Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Uzuazomaro%20Oju">Joseph Uzuazomaro Oju</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ease at which manipulated media can be created, and the increasing difficulty in identifying fake media makes it a great threat. Most of the applications used for the creation of these high-quality fake videos and images are built with deep learning. Hence, the use of deep learning in creating a detection mechanism cannot be overemphasized. Any successful fake media that is being detected before it reached the populace will save people from the self-doubt of either a content is genuine or fake and will ensure the credibility of videos and images. The methodology introduced in this paper approaches the manipulated media detection challenge using a combo of VGG-19 and a deep capsule network. In the case of videos, they are converted into frames, which, in turn, are resized and cropped to the face region. These preprocessed images/videos are fed to the VGG-19 network to extract the latent features. The extracted latent features are inputted into a deep capsule network enhanced with a 3D -convolution dynamic routing agreement. The 3D –convolution dynamic routing agreement algorithm helps to reduce the linkages between capsules networks. Thereby limiting the poor learning shortcoming of multiple capsule network layers. The resultant output from the deep capsule network will indicate a media to be either genuine or fake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20capsule%20network" title="deep capsule network">deep capsule network</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20routing" title=" dynamic routing"> dynamic routing</a>, <a href="https://publications.waset.org/abstracts/search?q=fake%20media%20detection" title=" fake media detection"> fake media detection</a>, <a href="https://publications.waset.org/abstracts/search?q=manipulated%20media" title=" manipulated media"> manipulated media</a> </p> <a href="https://publications.waset.org/abstracts/123371/detecting-manipulated-media-using-deep-capsule-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123371.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">134</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">1863</span> Aerodynamic Design Optimization Technique for a Tube Capsule That Uses an Axial Flow Air Compressor and an Aerostatic Bearing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20E.%20Hodaib">Ahmed E.

Hashem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-speed transportation has become a growing concern. To increase high-speed efficiencies and minimize power consumption of a vehicle, we need to eliminate the friction with the ground and minimize the aerodynamic drag acting on the vehicle. Due to the complexity and high power requirements of electromagnetic levitation, we make use of the air in front of the capsule, that produces the majority of the drag, to compress it in two phases and inject a proportion of it through small nozzles to make a high-pressure air cushion to levitate the capsule. The tube is partially-evacuated so that the air pressure is optimized for maximum compressor effectiveness, optimum tube size, and minimum vacuum pump power consumption. The total relative mass flow rate of the tube air is divided into two fractions. One is by-passed to flow over the capsule body, ensuring that no chocked flow takes place. The other fraction is sucked by the compressor where it is diffused to decrease the Mach number (around 0.8) to be suitable for the compressor inlet. The air is then compressed and intercooled, then split. One fraction is expanded through a tail nozzle to contribute to generating thrust. The other is compressed again. Bleed from the two compressors is used to maintain a constant air pressure in an air tank. The air tank is used to supply air for levitation. Dividing the total mass flow rate increases the achievable speed (Kantrowitz limit), and compressing it decreases the blockage of the capsule. As a result, the aerodynamic drag on the capsule decreases. As the tube pressure decreases, the drag decreases and the capsule power requirements decrease, however, the vacuum pump consumes more power. That’s why Design optimization techniques are to be used to get the optimum values for all the design variables given specific design inputs. Aerodynamic shape optimization, Capsule and tube sizing, compressor design, diffuser and nozzle expander design and the effect of the air bearing on the aerodynamics of the capsule are to be considered. The variations of the variables are to be studied for the change of the capsule velocity and air pressure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tube-capsule" title="tube-capsule">tube-capsule</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperloop" title=" hyperloop"> hyperloop</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20design%20optimization" title=" aerodynamic design optimization"> aerodynamic design optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20compressor" title=" air compressor"> air compressor</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20bearing" title=" air bearing"> air bearing</a> </p> <a href="https://publications.waset.org/abstracts/59173/aerodynamic-design-optimization-technique-for-a-tube-capsule-that-uses-an-axial-flow-air-compressor-and-an-aerostatic-bearing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59173.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">330</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">1862</span> Wireless Capsule Endoscope - Antenna and Channel Characterization </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Elhelbawy">Mona Elhelbawy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mac%20Gray"> Mac Gray</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional wired endoscopy is an intrusive process that requires a long flexible tube to be inserted through the patient’s mouth while intravenously sedated. Only images of the upper 4 feet of stomach, colon, and rectum can be captured, leaving the remaining 20 feet of small intestines. Wireless capsule endoscopy offers a painless, non-intrusive, efficient and effective alternative to traditional endoscopy. In wireless capsule endoscopy (WCE), ingestible vitamin-pill-shaped capsules with imaging capabilities, sensors, batteries, and antennas are designed to send images of the gastrointestinal (GI) tract in real time. In this paper, we investigate the radiation performance and specific absorption rate (SAR) of a miniature conformal capsule antenna operating at the Medical Implant Communication Service (MICS) frequency band in the human body. We perform numerical simulations using the finite element method based commercial software, high-frequency structure simulator (HFSS) and the ANSYS human body model (HBM). We also investigate the in-body channel characteristics between the implantable capsule and an external antenna placed on the surface of the human body. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IEEE%20802.15.6" title="IEEE 802.15.6">IEEE 802.15.6</a>, <a href="https://publications.waset.org/abstracts/search?q=MICS" title=" MICS"> MICS</a>, <a href="https://publications.waset.org/abstracts/search?q=SAR" title=" SAR"> SAR</a>, <a href="https://publications.waset.org/abstracts/search?q=WCE" title=" WCE"> WCE</a> </p> <a href="https://publications.waset.org/abstracts/129035/wireless-capsule-endoscope-antenna-and-channel-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129035.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">127</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">1861</span> Attachments of the Distal Oblique Membrane and Distal Oblique Bundle to the Distal Radioulnar Joint Capsule and Septum of Extensor Tendon Sheath</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Seu">Yuri Seu</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Kyu%20Choi"> Seong-Kyu Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Jin%20Park"> Hyun Jin Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Seo%20Park"> Jin Seo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=HongtaeKim"> HongtaeKim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi-Sun%20Hur"> Mi-Sun Hur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to clarify the attachments of the distal oblique membrane (DOM) and distal oblique bundle (DOB) of the interosseous membrane of the forearm. The distal oblique membrane was investigated in the 21 specimens of 11 Korean cadavers. The muscles in the forearms were removed to observe the DOB. The DOB was found in 13 of 21 specimens (61.9 %). The DOB was attached to the distal radioulnar joint capsule and the septum between the tendons of the extensor digiti minimi (EDM) and extensor carpi ulnaris (ECU) as well as the radius and ulna. In the cases that the DOB was absent, a part of the DOM extended to the distal radioulnar joint capsule and the septum between the tendons of the EDM and ECU, as well as the radius and ulna in all specimens (100%). The DOM, including the DOB, was arranged obliquely in the anteroposterior direction, whereas the intermediate part of the interosseous membrane was arranged in the same plane between the radius and ulna. The extension of the DOM and DOB to the wrist region may stabilize the distal radioulnar joint during supination and pronation. These data will be useful when performing reconstructive surgeries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distal%20oblique%20membrane" title="distal oblique membrane">distal oblique membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=distal%20oblique%20bundle" title=" distal oblique bundle"> distal oblique bundle</a>, <a href="https://publications.waset.org/abstracts/search?q=distal%20radioulnar%20joint%20capsule" title=" distal radioulnar joint capsule"> distal radioulnar joint capsule</a>, <a href="https://publications.waset.org/abstracts/search?q=interosseous%20membrane" title=" interosseous membrane"> interosseous membrane</a> </p> <a href="https://publications.waset.org/abstracts/167714/attachments-of-the-distal-oblique-membrane-and-distal-oblique-bundle-to-the-distal-radioulnar-joint-capsule-and-septum-of-extensor-tendon-sheath" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167714.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">91</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">1860</span> Material Properties Evolution Affecting Demisability for Space Debris Mitigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chetan%20Mahawar">Chetan Mahawar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarath%20Chandran"> Sarath Chandran</a>, <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20Panigrahi"> Sridhar Panigrahi</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20P.%20Shaji"> V.

The selection of material and operating conditions is determined with the objective of lightweight structure and ability to demise faster subject to spacecraft survivability during its mission. Since the demisability of spacecraft depends on evolving thermal material properties such as emissivity, specific heat capacity, thermal conductivity, radiation intensity, etc. Therefore, this paper presents the analysis of evolving thermal material properties of spacecraft, which affect the demisability process and thus estimate demise time using the demisability model by incorporating evolving thermal properties for sensible heating followed by the complete or partial break-up of spacecraft. The demisability analysis thus concludes the best suitable spacecraft material is based on the least estimated demise time, which fulfills the criteria of design-for-survivability and as well as of design-for-demisability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demisability" title="demisability">demisability</a>, <a href="https://publications.waset.org/abstracts/search?q=emissivity" title=" emissivity"> emissivity</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight" title=" lightweight"> lightweight</a>, <a href="https://publications.waset.org/abstracts/search?q=re-entry" title=" re-entry"> re-entry</a>, <a href="https://publications.waset.org/abstracts/search?q=survivability" title=" survivability"> survivability</a> </p> <a href="https://publications.waset.org/abstracts/155073/material-properties-evolution-affecting-demisability-for-space-debris-mitigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155073.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">116</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">1859</span> A Dissipative Particle Dynamics Study of a Capsule in Microfluidic Intracellular Delivery System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nishanthi%20N.%20S.">Nishanthi N.

Usually, vector-based methods, such as liposomes and polymeric materials, and physical methods, such as electroporation and sonoporation have been used for introducing nucleic acids or proteins. Reliance on exogenous materials, toxicity, off-target effects was the short-comings of these methods. Microinjection was an alternative process which addressed the above drawbacks. However, its low throughput had hindered its adoption widely. Mechanical deformation of cells by squeezing them through constriction channel can cause the temporary development of pores that would facilitate non-targeted diffusion of materials. Advantages of this method include high efficiency in intracellular delivery, a wide choice of materials, improved viability and high throughput. This cell squeezing process can be studied deeper by employing simple models and efficient computational procedures. In our current work, we present a finite sized dissipative particle dynamics (FDPD) model to simulate the dynamics of the cell flowing through a constricted channel. The cell is modeled as a capsule with FDPD particles connected through a spring network to represent the membrane. The total energy of the capsule is associated with linear and radial springs in addition to constraint of the fixed area. By performing detailed simulations, we studied the strain on the membrane of the capsule for channels with varying constriction heights. The strain on the capsule membrane was found to be similar though the constriction heights vary. When strain on the membrane was correlated to the development of pores, we found higher porosity in capsule flowing in wider channel. This is due to localization of strain to a smaller region in the narrow constriction channel. But the residence time of the capsule increased as the channel constriction narrowed indicating that strain for an increased time will cause less cell viability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capsule" title="capsule">capsule</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20squeezing" title=" cell squeezing"> cell squeezing</a>, <a href="https://publications.waset.org/abstracts/search?q=dissipative%20particle%20dynamics" title=" dissipative particle dynamics"> dissipative particle dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=intracellular%20delivery" title=" intracellular delivery"> intracellular delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidics" title=" microfluidics"> microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulations" title=" numerical simulations"> numerical simulations</a> </p> <a href="https://publications.waset.org/abstracts/100996/a-dissipative-particle-dynamics-study-of-a-capsule-in-microfluidic-intracellular-delivery-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100996.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">140</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">1858</span> Progressive Participatory Observation Applied to Priority Neighbourhoods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serge%20Rohmer">Serge Rohmer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a progressive participatory observation that can be used as a sociological investigation within communities.

Canola and mustard species that are in Brassicaceae family have too high contribution to world herbal production. In this study, genotypes of two kinds of (Caravel and Excalibul) canola (Brassica napus), wild mustard (Sinapis arvensis), white mustard (Sinapis alba) and Camelina (Camelina sativa) were grown in the experimental field, and their morphological characteristics were determined. According to the results of the research; plant length was varied between 76.75 cm and 151.50 cm, and the longest plant was belonging to species of Sinapis arvensis. The number of branches varied from 3.75 piece/plant to 17.75 piece/plant and the most numerous branch was counted in species of Sinapis alba. It was determined that the number of grains in one capsule was between 3.75 piece/capsule and 35.75 piece/capsule and the largest amount of grains in the one capsule was in the Excalibul variety of species of Brassica napus. In our research, it has been determined that the plant of Sinapis arvensis is a potential plant for industrial of oil production; such as Brassica napus, Sinapis alba and Camelina (Camelina sativa). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brassica%20napus" title="Brassica napus">Brassica napus</a>, <a href="https://publications.waset.org/abstracts/search?q=Camelina%20sativa" title=" Camelina sativa"> Camelina sativa</a>, <a href="https://publications.waset.org/abstracts/search?q=canola" title=" canola"> canola</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinapis%20alba" title=" Sinapis alba"> Sinapis alba</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinapis%20arvensis" title=" Sinapis arvensis"> Sinapis arvensis</a>, <a href="https://publications.waset.org/abstracts/search?q=wild%20mustard" title=" wild mustard"> wild mustard</a> </p> <a href="https://publications.waset.org/abstracts/77975/determination-of-morphological-characteristics-of-brassica-napus-sinapis-arvensis-sinapis-alba-and-camelina-sativa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77975.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">199</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">1856</span> Feature Extraction Based on Contourlet Transform and Log Gabor Filter for Detection of Ulcers in Wireless Capsule Endoscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nimisha%20Elsa%20Koshy">Nimisha Elsa Koshy</a>, <a href="https://publications.waset.org/abstracts/search?q=Varun%20P.%20Gopi"> Varun P.

Wireless Capsule Endoscopy (WCE) is a low risk, painless, noninvasive procedure for diagnosing diseases such as bleeding, polyps, ulcers, and Crohns disease within the human digestive tract, especially the small intestine that was unreachable using the traditional endoscopic methods. However, analysis of massive images of WCE detection is tedious and time consuming to physicians. Hence, researchers have developed software methods to detect these diseases automatically. Thus, the effectiveness of WCE can be improved. In this paper, a novel textural feature extraction method is proposed based on Contourlet transform and Log Gabor filter to distinguish ulcer regions from normal regions. The results show that the proposed method performs well with a high accuracy rate of 94.16% using Support Vector Machine (SVM) classifier in HSV colour space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contourlet%20transform" title="contourlet transform">contourlet transform</a>, <a href="https://publications.waset.org/abstracts/search?q=log%20gabor%20filter" title=" log gabor filter"> log gabor filter</a>, <a href="https://publications.waset.org/abstracts/search?q=ulcer" title=" ulcer"> ulcer</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20capsule%20endoscopy" title=" wireless capsule endoscopy"> wireless capsule endoscopy</a> </p> <a href="https://publications.waset.org/abstracts/17330/feature-extraction-based-on-contourlet-transform-and-log-gabor-filter-for-detection-of-ulcers-in-wireless-capsule-endoscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17330.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">540</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">1855</span> A Non-Destructive TeraHertz System and Method for Capsule and Liquid Medicine Identification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ke%20Lin">Ke Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Steve%20Wu%20Qing%20Yang"> Steve Wu Qing Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Nan"> Zhang Nan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The medicine and drugs has in the past been manufactured to the final products and then used laboratory analysis to verify their quality. However the industry needs crucially a monitoring technique for the final batch to batch quality check. The introduction of process analytical technology (PAT) provides an incentive to obtain real-time information about drugs on the production line, with the following optical techniques being considered: near-infrared (NIR) spectroscopy, Raman spectroscopy and imaging, mid-infrared spectroscopy with the use of chemometric techniques to quantify the final product. However, presents problems in that the spectra obtained will consist of many combination and overtone bands of the fundamental vibrations observed, making analysis difficult.

Over the years, election observation continues to play critical role in the electoral process specifically in Nigeria and Africa at large. Election observation keeps an eye on the electoral process and all the stakeholders during elections, to ensure that the process is fair to all contestants. While literature abound on this role of election observation on electoral process in Nigeria, scanty scholarly efforts have been made to appraise how election observation influences electoral reforms in Nigeria. Also, while election observation may play a role in ensuring that the electoral process is credible, specifically, its role in prvoking and eliciting various electoral reforms in the country has not been explored. The paper adopts the explanatory research design using secondary data and document analysis. Preliminary findings show that election observation has influenced electoral reforms in Nigeria in no small measure. The paper concludes that election observation is critical for result oriented electoral reforms in Nigeria, albeit, such reforms have to be implemented to the latter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electoral%20reforms" title="electoral reforms">electoral reforms</a>, <a href="https://publications.waset.org/abstracts/search?q=election%20observation" title=" election observation"> election observation</a>, <a href="https://publications.waset.org/abstracts/search?q=electoral%20process" title=" electoral process"> electoral process</a>, <a href="https://publications.waset.org/abstracts/search?q=developing%20country" title=" developing country"> developing country</a> </p> <a href="https://publications.waset.org/abstracts/123813/the-impact-of-election-observation-on-electoral-reforms-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123813.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">165</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">1853</span> Optimizing the Capacity of a Convolutional Neural Network for Image Segmentation and Pattern Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yalong%20Jiang">Yalong Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zheru%20Chi"> Zheru Chi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study the factors which determine the capacity of a Convolutional Neural Network (CNN) model and propose the ways to evaluate and adjust the capacity of a CNN model for best matching to a specific pattern recognition task.

Secondly, the number of independent functional units in the capsule network is adjusted to fit it to the training dataset. Thirdly, a method based on Bayesian GAN is proposed to enrich the variances in the current dataset to increase its complexity. Experimental results on the PASCAL VOC 2010 Person Part dataset and the MNIST dataset show that, in both conventional CNN models and capsule networks, the number of independent functional units is an important factor that determines the capacity of a network model.

To develop high-speed rails and to increase high-speed efficiencies, the idea of Hyperloop was introduced. The challenge is to overcome the difficulties of managing friction and air-resistance which become substantial when vehicles approach high speeds. In this paper, we are presenting the methodologies of the capsule design which got a design concept innovation award at SpaceX competition in January, 2016. MATLAB scripts are written for the levitation and propulsion calculations and iterations. Computational Fluid Dynamics (CFD) is used to simulate the air flow around the capsule considering the effect of the axial-flow air compressor and the levitation cushion on the air flow. The design procedures of a single-sided linear induction motor are analyzed in detail and its geometric and magnetic parameters are determined. A structural design is introduced and Finite Element Method (FEM) is used to analyze the stresses in different parts. The configuration and the arrangement of the components are illustrated.

This study aims to develop the three-dimensional numerical method for precise computation and the surface panel method for rapid engineering prediction. Detailed flow field analysis for Mars exploration mission was performed by carrying on a series of fully three-dimensional Navier-Stokes computations. The static aerodynamic performance was then discussed, including the surface pressure, lift and drag coefficient, lift-to-drag ratio with the numerical and engineering method. Computation results shown that the shock layer is thin because of lower effective specific heat ratio, and that calculated results from both methods agree well with each other, and is consistent with the reference data. Aerodynamic performance analysis shows that CG location determines trim characteristics and pitch stability, and certain radially and axially shift of the CG location can alter the capsule lifting entry performance, which is of vital significance for the aerodynamic configuration des0ign and inner instrument layout of the Mars entry capsule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mars%20entry%20capsule" title="Mars entry capsule">Mars entry capsule</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20aerodynamics" title=" static aerodynamics"> static aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersonic" title=" hypersonic"> hypersonic</a> </p> <a href="https://publications.waset.org/abstracts/22909/aerodynamic-prediction-and-performance-analysis-for-mars-science-laboratory-entry-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22909.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">299</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">1848</span> Contourlet Transform and Local Binary Pattern Based Feature Extraction for Bleeding Detection in Endoscopic Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mekha%20Mathew">Mekha Mathew</a>, <a href="https://publications.waset.org/abstracts/search?q=Varun%20P%20Gopi"> Varun P Gopi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless Capsule Endoscopy (WCE) has become a great device in Gastrointestinal (GI) tract diagnosis, which can examine the entire GI tract, especially the small intestine without invasiveness and sedation.

The toxicity of Methidathion, Malathion, Deltamethrin, and Lufenuron to adult males and females of Acanthiophilus helianthi was studied under laboratory conditions. Malathion was the most toxic among the tested compounds followed by Methidathion, Lufenuron, and Deltamethrin to Acanthiophilus helianthi at 24 h post treatment, the respective LC50 values were 0.40 ppm, 0.68 ppm, 10.99 ppm, and 11.75 ppm for males and 0.46 ppm, 0.97 ppm, 13.45 ppm, and 16.32 ppm for females. At 48 h post treatment, Malathion was the most toxic followed by Methidathion, Deltamethrin, and Lufenuron to Acanthiophilus helianthi, LC50 values were 0.08 ppm, 0.54 ppm, 1.80 ppm, and 1.96 ppm for males and 0.34 ppm, 0.64 ppm, 1.88 ppm, and 2.37 ppm for females. At 72 h post treatment, Malathion was the most toxic followed by Methidathion, Lufenuron, and Deltamethrin to Acanthiophilus helianthi LC50 values were 0.04 ppm, 0.33 ppm, 0.44 ppm, and 0.71 ppm for males and 0.09 ppm, 0.36 ppm, 0.75 ppm, and 0.82 ppm for females. It is observed that LC50 values for treated adult females increased more than in the treated adult males at 24 h, 48 h, and 72 h post treatment. It means that the adult males were more susceptible to the tested insecticides than the adult females. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=safflower" title="safflower">safflower</a>, <a href="https://publications.waset.org/abstracts/search?q=Methidathion" title=" Methidathion"> Methidathion</a>, <a href="https://publications.waset.org/abstracts/search?q=Deltamethrin" title=" Deltamethrin"> Deltamethrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lufenuron" title=" Lufenuron"> Lufenuron</a>, <a href="https://publications.waset.org/abstracts/search?q=Malathion" title=" Malathion"> Malathion</a>, <a href="https://publications.waset.org/abstracts/search?q=Tephritidae" title=" Tephritidae"> Tephritidae</a>, <a href="https://publications.waset.org/abstracts/search?q=safflower%20capsule%20fly" title=" safflower capsule fly"> safflower capsule fly</a>, <a href="https://publications.waset.org/abstracts/search?q=Acanthiophilus%20helianthi" title=" Acanthiophilus helianthi "> Acanthiophilus helianthi </a> </p> <a href="https://publications.waset.org/abstracts/17503/relative-toxicity-of-apparent-pesticides-against-safflower-capsule-fly-acanthiophilus-helianthi-rossi-diptera-tephritidae-under-laboratory-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17503.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">334</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">1845</span> Efficacy of Cool's and Rhythmic Stabilization Exercises on Scapular up Ward Rotation and Ut/Sa Ratio in Patients with Shoulder Impingement Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Moustafa">Mohammed Moustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Ayad"> Khaled Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Reda"> Waleed Reda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shoulder impingement syndrome is the most common disorder of the shoulder, resulting in functional loss and disability. Objective: This study was designed to compare between the effects of scapular muscle training versus rhythmic stabilization exercises in treatment of shoulder impingement syndrome. Methods: Thirty patients participated in this study; they were assigned randomly into two experimental groups. The first experimental group (A) consisted of 15 patients with a mean age (21.87±2.72) years; they received graduated rhythmic stabilization exercises and stretching of the posterior capsule. The second experimental group (B) consisted of 15 patients with a mean age (22.27±2.94) years; they received scapular muscle training exercises in addition to stretching of the posterior capsule. Treatment was given three times per week, every other day, for four consecutive weeks. Patients have been evaluated pretreatment and post treatment for shoulder pain severity and functional disability. Results: Both groups showed highly statistical significant reduction in pain severity and functional disability measured post-treatment when compared with their corresponding values in pretreatment assessment.

E. Smith) (Lepidoptera, Noctuidae) has recently become one of the major threats to maize production in the world. It is native to tropical and subtropical America and began to spread to many African and a few Asian Countries. A survey for the observation of infestation and collection of fall armyworm was conducted in field planted with maize in the northern part of Katsina state. Eggs and immature stages were collected, place in a plastic container and brought to the laboratory for observation and study of developmental stages. FAW was identified based on the morphological characteristics, i.e. the “Y” inverted shape on the head capsule and the patterns of black spots on the abdominal segments (square and trapezoidal forms). Different growing stage of maize are affected by fall armyworm, but the damage is greatest during the early growing phase of corn. Heavy infestation on the leaves also cause defoliation. Four developmental stages (eggs larvae, pupae and adults) of the FAW were studied when fed with young corn under laboratory conditions. Furthermore, effective scouting or monitoring of FAW could be practice at early stage of growth of maize. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infestation" title="infestation">infestation</a>, <a href="https://publications.waset.org/abstracts/search?q=katsina" title=" katsina"> katsina</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=fall%20armyworm" title=" fall armyworm"> fall armyworm</a> </p> <a href="https://publications.waset.org/abstracts/180992/occurrence-of-the-fall-armyworm-spodoptera-frugiperda-j-e-smith-lepidoptera-noctuidae-on-maize-in-katsina-state-nigeria-and-preliminary-study-of-its-developmental-characteristics-under-laboratory-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180992.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">74</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">1843</span> The Influence of Mechanical and Physicochemical Characteristics of Perfume Microcapsules on Their Rupture Behaviour and How This Relates to Performance in Consumer Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Gray">Andrew Gray</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhibing%20Zhang"> Zhibing Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ability for consumer products to deliver a sustained perfume response can be a key driver for a variety of applications. Many compounds in perfume oils are highly volatile, meaning they readily evaporate once the product is applied, and the longevity of the scent is poor. Perfume capsules have been introduced as a means of abating this evaporation once the product has been delivered. The impermeable capsules are aimed to be stable within the formulation, and remain intact during delivery to the desired substrate, only rupturing to release the core perfume oil through application of mechanical force applied by the consumer. This opens up the possibility of obtaining an olfactive response hours, weeks or even months after delivery, depending on the nature of the desired application. Tailoring the properties of the polymeric capsules to better address the needs of the application is not a trivial challenge and currently design of capsules is largely done by trial and error. The aim of this work is to have more predictive methods for capsule design depending on the consumer application. This means refining formulations such that they rupture at the right time for the specific consumer application, not too early, not too late. Finding the right balance between these extremes is essential if a benefit is sought with respect to neat addition of perfume to formulations. It is important to understand the forces that influence capsule rupture, first, by quantifying the magnitude of these different forces, and then by assessing bulk rupture in real-world applications to understand how capsules actually respond. Samples were provided by an industrial partner and the mechanical properties of individual capsules within the samples were characterized via a micromanipulation technique, developed by Professor Zhang at the University of Birmingham. The capsules were synthesized such as to change one particular physicochemical property at a time, such as core: wall material ratio, and the average size of capsules. Analysis of shell thickness via Transmission Electron Microscopy, size distribution via the use of a Mastersizer, as well as a variety of other techniques confirmed that only one particular physicochemical property was altered for each sample. The mechanical analysis was subsequently undertaken, showing the effect that changing certain capsule properties had on the response under compression. It was, however, important to link this fundamental mechanical response to capsule performance in real-world applications. As such, the capsule samples were introduced to a formulation and exposed to full scale stresses. GC-MS headspace analysis of the perfume oil released from broken capsules enabled quantification of what the relative strengths of capsules truly means for product performance. Correlations have been found between the mechanical strength of capsule samples and performance in terms of perfume release in consumer applications. Having a better understanding of the key parameters that drive performance benefits the design of future formulations by offering better guidelines on the parameters that can be adjusted without worrying about the performance effects, and singles out those parameters that are essential in finding the sweet spot for capsule performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20products" title="consumer products">consumer products</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20and%20physicochemical%20properties" title=" mechanical and physicochemical properties"> mechanical and physicochemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=perfume%20capsules" title=" perfume capsules"> perfume capsules</a>, <a href="https://publications.waset.org/abstracts/search?q=rupture%20behaviour" title=" rupture behaviour"> rupture behaviour</a> </p> <a href="https://publications.waset.org/abstracts/87689/the-influence-of-mechanical-and-physicochemical-characteristics-of-perfume-microcapsules-on-their-rupture-behaviour-and-how-this-relates-to-performance-in-consumer-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87689.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">131</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">1842</span> Reduction of Patient’s Dose of I-131 Therapy by Used Local Diuretic Juice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mosab%20kh.%20A.%20A.%20Bashir">Mosab kh.

It was observed that the external exposure from the second group clearly decreased to low levels which contributed to the decrease in patient dose and also to the decrease in the exposure from the patient to his/her family. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=local%20diuretic%20juice" title="local diuretic juice">local diuretic juice</a>, <a href="https://publications.waset.org/abstracts/search?q=therapy" title=" therapy"> therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20medicine" title=" radiation medicine"> radiation medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=diuretic%20plant" title=" diuretic plant"> diuretic plant</a> </p> <a href="https://publications.waset.org/abstracts/4035/reduction-of-patients-dose-of-i-131-therapy-by-used-local-diuretic-juice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4035.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">315</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1841</span> Powder Assisted Sheet Forming to Fabricate Ti Capsule Magnetic Hyperthermia Implant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keigo%20Nishitani">Keigo Nishitani</a>, <a href="https://publications.waset.org/abstracts/search?q=Kohei%20Mizuta%20Mizuta"> Kohei Mizuta Mizuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuyoshi%20Kurita"> Kazuyoshi Kurita</a>, <a href="https://publications.waset.org/abstracts/search?q=Yukinori%20Taniguchi"> Yukinori Taniguchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To establish mass production process of Ti capsule which has Fe powder inside as magnetic hyperthermia implant, we assumed that Ti thin sheet can be drawn into a φ1.0 mm die hole through the medium of Fe Powder and becomes outer shell of capsule. This study discusses mechanism of powder assisted deep drawing process by both of numerical simulation and experiment. Ti thin sheet blank was placed on die, and was covered by Fe powder layer without pressurizing. Then upper punch was indented on the Fe powder layer, and the blank can be drawn into die cavity as pressurized powder particles were extruded into die cavity from behind of the drawn blank. Distinct Element Method (DEM) has been used to demonstrate the process. To identify bonding parameters on Fe particles which are cohesion, tensile bond stress and inter particle friction angle, axial and diametrical compression failure test of Fe powder compact was conducted. Several density ratios of powder compacts in range of 0.70 - 0.85 were investigated and relationship between mean stress and equivalent stress was calculated with consideration of critical state line which rules failure criterion in consolidation of Fe powder. Since variation of bonding parameters with density ratio has been experimentally identified, and good agreement has been recognized between several failure tests and its simulation, demonstration of powder assisted sheet forming by using DEM becomes applicable. Results of simulation indicated that indent/drawing length of Ti thin sheet is promoted by smaller Fe particle size, larger indent punch diameter, lower friction coefficient between die surface and Ti sheet and certain degrees of die inlet taper angle. In the deep drawing test, we have made die-set with φ2.4 mm punch and φ1.0 mm die bore diameter. Pure Ti sheet with 100 μm thickness, annealed at 650 deg. C has been tested. After indentation, indented/drawn capsule has been observed by microscope, and its length was measured to discuss the feasibility of this capsulation process. Longer drawing length exists on progressive loading pass comparing with the case of single stroke loading. It is expected that progressive loading has an advantage of which extrusion of powder particle into die cavity with Ti sheet is promoted since powder particle layer can be rebuilt while the punch is withdrawn from the layer in each loading steps. This capsulation phenomenon is qualitatively demonstrated by DEM simulation. Finally, we have fabricated Ti capsule which has Fe powder inside for magnetic hyperthermia cancer care treatment. It is concluded that suggested method is possible to use the manufacturing of Ti capsule implant for magnetic hyperthermia cancer care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal%20powder%20compaction" title="metal powder compaction">metal powder compaction</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20forming" title=" metal forming"> metal forming</a>, <a href="https://publications.waset.org/abstracts/search?q=distinct%20element%20method" title=" distinct element method"> distinct element method</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20care" title=" cancer care"> cancer care</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20hyperthermia" title=" magnetic hyperthermia"> magnetic hyperthermia</a> </p> <a href="https://publications.waset.org/abstracts/72896/powder-assisted-sheet-forming-to-fabricate-ti-capsule-magnetic-hyperthermia-implant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72896.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">298</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">1840</span> A Case Report on Diaphragm Disease of Small Bowel Following Usage of Non-Steroidal Anti-Inflammatory Drugs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shivani%20Kuttuva">Shivani Kuttuva</a>, <a href="https://publications.waset.org/abstracts/search?q=Bridget%20Fergie"> Bridget Fergie</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Mishreki"> Andrew Mishreki</a>, <a href="https://publications.waset.org/abstracts/search?q=Shovkat%20Mir"> Shovkat Mir</a>, <a href="https://publications.waset.org/abstracts/search?q=Fintan%20Bergin"> Fintan Bergin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diaphragm disease (DD) of the small bowel is a condition wherein the bowel lumen is divided into a series of short compartments by multiple circumferential membranes of mucosa and submucosa, leading to pinhole lumen and subsequent obstruction. It is a rare condition commonly attributed to non-steroidal anti-inflammatory drugs (NSAIDs) usage. Herein we present a 31-yr-old-female with a history of NSAIDs usage for one year following neurosurgery, who presented with recurrent idiopathic small bowel obstruction, recalcitrant anaemia, and impaction of capsule endoscope on investigating for anaemia. The capsule endoscopy images demonstrated multiple circumferential strictures with ulcers at its tip and villous atrophy in the proximal bowel, suggestive of NSAIDs related damage. However, due to the lack of awareness of the detrimental effects of NSAIDs on bowel mucosa distal to the duodenum, the underlying aetiology of this clinical presentation remained a mystery for a significant duration. The patient had to undergo repeated laparotomies in order to relieve the symptoms of recurring acute small bowel obstruction. Upon examining the resected specimen under microscopy, the histopathological hallmark of expanded, fibrotic, and congested submucosa was picked up, leading to the confirmation of diaphragm disease. Thus, this case report aims to widen the awareness among clinicians and aid surgeons in devising a management plan for young individuals presenting with recurring episodes of obstruction due to Diaphragm disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capsule%20endoscopy" title="capsule endoscopy">capsule endoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=diaphragm%20disease" title=" diaphragm disease"> diaphragm disease</a>, <a href="https://publications.waset.org/abstracts/search?q=NSAIDs" title=" NSAIDs"> NSAIDs</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20small%20bowel%20obstruction" title=" recurrent small bowel obstruction"> recurrent small bowel obstruction</a> </p> <a href="https://publications.waset.org/abstracts/148989/a-case-report-on-diaphragm-disease-of-small-bowel-following-usage-of-non-steroidal-anti-inflammatory-drugs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148989.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">170</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">1839</span> Thick Data Techniques for Identifying Abnormality in Video Frames for Wireless Capsule Endoscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinan%20Fiaidhi">Jinan Fiaidhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabah%20Mohammed"> Sabah Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Petros%20Zezos"> Petros Zezos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Capsule endoscopy (CE) is an established noninvasive diagnostic modality in investigating small bowel disease. CE has a pivotal role in assessing patients with suspected bleeding or identifying evidence of active Crohn's disease in the small bowel. However, CE produces lengthy videos with at least eighty thousand frames, with a frequency rate of 2 frames per second. Gastroenterologists cannot dedicate 8 to 15 hours to reading the CE video frames to arrive at a diagnosis. This is why the issue of analyzing CE videos based on modern artificial intelligence techniques becomes a necessity. However, machine learning, including deep learning, has failed to report robust results because of the lack of large samples to train its neural nets. In this paper, we are describing a thick data approach that learns from a few anchor images. We are using sound datasets like KVASIR and CrohnIPI to filter candidate frames that include interesting anomalies in any CE video. We are identifying candidate frames based on feature extraction to provide representative measures of the anomaly, like the size of the anomaly and the color contrast compared to the image background, and later feed these features to a decision tree that can classify the candidate frames as having a condition like the Crohn's Disease. Our thick data approach reported accuracy of detecting Crohn's Disease based on the availability of ulcer areas at the candidate frames for KVASIR was 89.9% and for the CrohnIPI was 83.3%. We are continuing our research to fine-tune our approach by adding more thick data methods for enhancing diagnosis accuracy. <p class="card-text"><strong>Keywords:</strong> <a
