This can have an impact on clustering wind speed characteristics in Indonesia. This study uses data daily wind speed observations of the Site Meteorological Station network for 30 years. Multicollinearity tests were also performed on all of these data before doing clustering with PCA. The results show that the four main components have a total diversity of above 80% which will be used for clusters. Division of clusters using Ward's method obtained 3 types of clusters. Cluster 1 covers the central part of Sumatra Island, northern Kalimantan, northern Sulawesi, and northern Maluku with the climatological pattern of wind speed that does not have an annual cycle and a weak speed throughout the year with a low-speed ranging from 0 to 1,5 m/s². Cluster 2 covers the northern part of Sumatra Island, South Sulawesi, Bali, northern Papua with the climatological pattern conditions of wind speed that have annual cycle variations with low speeds ranging from 1 to 3 m/s². Cluster 3 covers the eastern part of Java Island, the Southeast Nusa Islands, and the southern Maluku Islands with the climatological pattern of wind speed conditions that have annual cycle variations with high speeds ranging from 1 to 4.5 m/s². <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PCA" title="PCA">PCA</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster" title=" cluster"> cluster</a>, <a href="https://publications.waset.org/abstracts/search?q=Ward%27s%20method" title=" Ward's method"> Ward's method</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20speed" title=" wind speed"> wind speed</a> </p> <a href="https://publications.waset.org/abstracts/132942/wind-velocity-climate-zonation-based-on-observation-data-in-indonesia-using-cluster-and-principal-component-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132942.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">195</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">126</span> Materiality of Gender Roles in Gede City State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Maina%20Muthegethi">David Maina Muthegethi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For decades, archaeological work of Swahili Civilization has mainly concentrated on exploration of economic and political dynamics of City states. This paper moves further and explore how gender roles were formed, maintained, negotiated and re-negotiated through time and space in Gede City. Unlike other Swahili city states, Gede was located around two miles away from the shores of Indian Ocean. Nonetheless, the city was characterized by security walls, stone houses, mosques and tombs typical of Swahili City states such as Kilwa. The study employed several methods of data collection namely: archival research, survey, re-examination of collected materials and excavation of Gede archaeological site. Since, the study aimed to examine gender roles across different social class, a total of three houses were excavated based on their social hierarchy. Thus, the houses were roughly categorized as belonging to elites, middle class and lower class. The house were located in the inner wall, second inner wall and the outer wall of Gede City respectively. Key findings shows that gender roles differed considerably along classes in Gede archaeological site. For instance, the women of the elite and middle class were active participants in Gede international trade through production and consumption of imported goods. This participation corresponded with commercialization of Gede households especially in elite’ areas where they hosted international traders. On the other hand, the middle class houses, women concentrated on running of light industries aimed at supplying goods for the urban community. Thus, they were able to afford exotic goods as their elites counterparts. Lastly, the gender roles of lower class entailed subsistence gender roles with little participation in Gede formal commerce. Interestingly, gender roles in Gede were dynamic in nature and response to cultural diffusion, spread of Islam, intensification of trade, diversification of subsistence patterns and urbanization. Therefore, this findings, demonstrate centrality of gender in reconstruction of social lives of Swahili Civilization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20roles" title="gender roles">gender roles</a>, <a href="https://publications.waset.org/abstracts/search?q=Islam" title=" Islam"> Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Swahili%20civilization" title=" Swahili civilization"> Swahili civilization</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanization" title=" urbanization"> urbanization</a> </p> <a href="https://publications.waset.org/abstracts/157828/materiality-of-gender-roles-in-gede-city-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157828.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">125</span> High-Resolution Flood Hazard Mapping Using Two-Dimensional Hydrodynamic Model Anuga: Case Study of Jakarta, Indonesia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hengki%20Eko%20Putra">Hengki Eko Putra</a>, <a href="https://publications.waset.org/abstracts/search?q=Dennish%20Ari%20Putro"> Dennish Ari Putro</a>, <a href="https://publications.waset.org/abstracts/search?q=Tri%20Wahyu%20Hadi"> Tri Wahyu Hadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Edi%20Riawan"> Edi Riawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Junnaedhi%20Dewa%20Gede"> Junnaedhi Dewa Gede</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditia%20Rojali"> Aditia Rojali</a>, <a href="https://publications.waset.org/abstracts/search?q=Fariza%20Dian%20Prasetyo"> Fariza Dian Prasetyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yudhistira%20Satya%20Pribadi"> Yudhistira Satya Pribadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dita%20Fatria%20Andarini"> Dita Fatria Andarini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mila%20Khaerunisa"> Mila Khaerunisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Raditya%20Hanung%20Prakoswa"> Raditya Hanung Prakoswa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Catastrophe risk management can only be done if we are able to calculate the exposed risks. Jakarta is an important city economically, socially, and politically and in the same time exposed to severe floods. On the other hand, flood risk calculation is still very limited in the area. This study has calculated the risk of flooding for Jakarta using 2-Dimensional Model ANUGA. 2-Dimensional model ANUGA and 1-Dimensional Model HEC-RAS are used to calculate the risk of flooding from 13 major rivers in Jakarta. ANUGA can simulate physical and dynamical processes between the streamflow against river geometry and land cover to produce a 1-meter resolution inundation map. The value of streamflow as an input for the model obtained from hydrological analysis on rainfall data using hydrologic model HEC-HMS. The probabilistic streamflow derived from probabilistic rainfall using statistical distribution Log-Pearson III, Normal and Gumbel, through compatibility test using Chi Square and Smirnov-Kolmogorov. Flood event on 2007 is used as a comparison to evaluate the accuracy of model output. Property damage estimations were calculated based on flood depth for 1, 5, 10, 25, 50, and 100 years return period against housing value data from the BPS-Statistics Indonesia, Centre for Research and Development of Housing and Settlements, Ministry of Public Work Indonesia. The vulnerability factor was derived from flood insurance claim. Jakarta's flood loss estimation for the return period of 1, 5, 10, 25, 50, and 100 years, respectively are Rp 1.30 t; Rp 16.18 t; Rp 16.85 t; Rp 21.21 t; Rp 24.32 t; and Rp 24.67 t of the total value of building Rp 434.43 t. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2D%20hydrodynamic%20model" title="2D hydrodynamic model">2D hydrodynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=ANUGA" title=" ANUGA"> ANUGA</a>, <a href="https://publications.waset.org/abstracts/search?q=flood" title=" flood"> flood</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20modeling" title=" flood modeling"> flood modeling</a> </p> <a href="https://publications.waset.org/abstracts/58115/high-resolution-flood-hazard-mapping-using-two-dimensional-hydrodynamic-model-anuga-case-study-of-jakarta-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58115.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">275</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">124</span> Formulation of Sun Screen Cream and Sun Protecting Factor Activity from Standardized–Partition Compound of Mahkota Dewa Leaf (Phaleria macrocarpa (Scheff.)

In this study, 13 formulations of cream oil in water (o/w) were prepared and tested for their physical characteristics. The physical characteristics were then used for determining the optimum formula. This study aimed to explore the physical stability of optimized formulation of cream, its sun protecting factor (SPF) values using in vitro and in vivo tests. The optimum formula of o/w cream were prepared based on Simplex Lattice Design (LSD) method using software Design Expert®. The formulation of o/w cream were varied based on the proportion of cetyl alcohol, mineral oil and tween 80. The difference of physical characteristic of optimum and predicted formula was tested using t-test with significant level of 95%. The optimum formula of o/w cream was the formula which consists of cetyl alcohol 9.71%, mineral oil, 29%, and tween 80 3.29. Based on t-test, there was no significant difference of physical characteristics of optimum and predicted formulation. Viscosity, spread power, adhesive power, and separation volume ratio of o/w at week 0-4 were relatively stable. The o/w creams were relatively stable at extreme temperature. The o/w creams from mahkota dewa, phalerin, and benzophenone have SPF values of 21.32, 33.12, and 42.49, respectively. The formulas did not irritate the skin based on in vivo test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cream" title="cream">cream</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20vitro" title=" In vitro"> In vitro</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20vivo" title=" In vivo"> In vivo</a> </p> <a href="https://publications.waset.org/abstracts/66716/formulation-of-sun-screen-cream-and-sun-protecting-factor-activity-from-standardized-partition-compound-of-mahkota-dewa-leaf-phaleria-macrocarpa-scheff-boerl" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66716.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">229</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">123</span> An Investigation on Engineering Students’ Perceptions towards E-Learning in the UK</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Razzaghifard%20P.">Razzaghifard P.</a>, <a href="https://publications.waset.org/abstracts/search?q=Arya%20F."> Arya F.</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20S.%20Chien-I"> Chen S.

One of the critical factors in the successful application of e-learning in higher education is students’ perceptions towards it. The main purpose of this paper is to investigate the perceptions of engineering students about e-learning in the UK. For the purpose of the present study, 145 second-year engineering students were randomly selected from the total population of 1280 participants. The participants were asked to complete a questionnaire containing 16 items. The data collected from the questionnaire were analyzed through the Statistical Package for Social Science (SPSS) software. The findings of the study revealed that the majority of participants have negative perceptions of e-learning. Most of the students had trouble interacting effectively during online classes. Furthermore, the majority of participants had negative experiences with the learning platform they used during e-learning. Suggestions were made on what could be done to improve the students’ perceptions of e-learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-learning" title="e-learning">e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=higher" title=" higher"> higher</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20education" title=" engineering education"> engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20learning" title=" online learning"> online learning</a> </p> <a href="https://publications.waset.org/abstracts/148727/an-investigation-on-engineering-students-perceptions-towards-e-learning-in-the-uk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148727.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">122</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">122</span> Towards a Competitive South African Tooling Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mncedisi%20Trinity%20Dewa">Mncedisi Trinity Dewa</a>, <a href="https://publications.waset.org/abstracts/search?q=Andre%20Francois%20Van%20Der%20Merwe"> Andre Francois Van Der Merwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Matope"> Stephen Matope</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tool, Die and Mould-making (TDM) firms have been known to play a pivotal role in the growth and development of the manufacturing sectors in most economies.

It inhibits the replication of DENV in Aedes aegypti. Both DENV and its vector, Aedes aegypty, are sensitive to climate factor especially temperature. The changing of climate has a direct impact on temperature which means changing the vector transmission. Temperature has been known to effect Wolbachia density as it has an ideal temperature to grow. Some scenarios, which are known as Representative Concentration Pathways (RCPs), have been developed by Intergovernmental Panel on Climate Change (IPCC) to predict the future climate based on greenhouse gases concentration. These scenarios are applied to mitigate the future change of Aedes aegypti migration and how Wolbachia could control the virus. The prediction will determine the schemes to release Wolbachia-injected Aedes aegypti to reduce DENV transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aedes%20aegypti" title="Aedes aegypti">Aedes aegypti</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=dengue%20virus" title=" dengue virus"> dengue virus</a>, <a href="https://publications.waset.org/abstracts/search?q=Intergovernmental%20Panel%20on%20Climate%20Change" title=" Intergovernmental Panel on Climate Change"> Intergovernmental Panel on Climate Change</a>, <a href="https://publications.waset.org/abstracts/search?q=representative%20concentration%20pathways" title=" representative concentration pathways"> representative concentration pathways</a>, <a href="https://publications.waset.org/abstracts/search?q=Wolbachia" title=" Wolbachia"> Wolbachia</a> </p> <a href="https://publications.waset.org/abstracts/64262/representative-concentration-pathways-approach-on-wolbachia-controlling-dengue-virus-in-aedes-aegypti" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64262.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">300</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">119</span> A System For A Sustainable Electronic Waste Marketplace</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arya%20Sarukkai">Arya Sarukkai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to increased technological advances and the high use of phones, tablets, computers, and other electronics, we continue to see rapid growth in the volume of e-waste. There are millions just throwing out their old devices, millions who have many devices and don’t know what to do with them, and there are millions who would benefit from receiving those devices. The thesis of this paper is that by creating an ecosystem of donors and recipients and providing the right incentives, we can reduce e-waste. We discuss a system for sustainable e-waste by building a marketplace between donors and recipients. We also summarize experimental results comparing different incentives and present a live web service that allows for e-waste supplies to reach schools and nonprofit institutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E-waste%20ecosystems" title="E-waste ecosystems">E-waste ecosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=marketplaces" title=" marketplaces"> marketplaces</a>, <a href="https://publications.waset.org/abstracts/search?q=e-waste%20web%20app" title=" e-waste web app"> e-waste web app</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20services" title=" online services"> online services</a> </p> <a href="https://publications.waset.org/abstracts/142966/a-system-for-a-sustainable-electronic-waste-marketplace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142966.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">197</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">118</span> R Software for Parameter Estimation of Spatio-Temporal Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Budi%20Nurani%20Ruchjana">Budi Nurani Ruchjana</a>, <a href="https://publications.waset.org/abstracts/search?q=Atje%20Setiawan%20Abdullah"> Atje Setiawan Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20Gede%20Nyoman%20Mindra%20Jaya"> I.

GSTAR is a combination of time series and spatial models that have parameters vary per location. We use the method of Ordinary Least Squares (OLS) and use the Mean Average Percentage Error (MAPE) to fit the model to spatiotemporal real phenomenon. For case study, we use oil production data from volcanic layer at Jatibarang Indonesia or climate data such as rainfall in Indonesia. Software R is very user-friendly and it is making calculation easier, processing the data is accurate and faster. Limitations R script for the estimation of model parameters spatiotemporal GSTAR built is still limited to a stationary time series model.

One can use the convolution code. This paper presents performance of OFDM using Space Time Block Codes (STBC) diversity technique use QAM modulation with code rate 1/2. The evaluation is done by analyzing the value of Bit Error Rate (BER) vs. Energy per Bit to Noise Power Spectral Density Ratio (Eb/No). This scheme is conducted 256 sub-carrier which transmits Rayleigh multipath channel in OFDM system. To achieve a BER of 10-3 is required 30 dB SNR in SISO-OFDM scheme. For 2x2 MIMO-OFDM scheme requires 10 dB to achieve a BER of 10-3. For 4x4 MIMO-OFDM scheme requires 5 dB while adding convolution in a 4x4 MIMO-OFDM can improve performance up to 0 dB to achieve the same BER. This proves the existence of saving power by 3 dB of 4x4 MIMO-OFDM system without coding, power saving 7 dB of 2x2 MIMO-OFDM system without coding and significant power savings from SISO-OFDM system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convolution%20code" title="convolution code">convolution code</a>, <a href="https://publications.waset.org/abstracts/search?q=OFDM" title=" OFDM"> OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=MIMO" title=" MIMO"> MIMO</a>, <a href="https://publications.waset.org/abstracts/search?q=QAM" title=" QAM"> QAM</a>, <a href="https://publications.waset.org/abstracts/search?q=BER" title=" BER"> BER</a> </p> <a href="https://publications.waset.org/abstracts/2398/performance-analysis-of-mimo-ofdm-using-convolution-codes-with-qam-modulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2398.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">114</span> Risk Identification of Investment Feasibility in Indonesia’s Toll Road Infrastructure Investment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christo%20Februanto%20Putra">Christo Februanto Putra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents risk identification that affects investment feasibility on toll road infrastructure in Indonesia using qualitative methods survey based on the expert practitioner in investor, contractor, and state officials.

Those cases caused harm to many people, even death, and lead to the continuation circle of violence. This research was conducted to evaluate the effect of using peace education and media literacy in enhancing student’s understanding about aggression, as an effort to prevent aggressive behavior. In terms of methodology, this research was done by quasi-experiment with one group pretest and post-test design. A number of 38 students who were at risk of aggressive behavior from 3 vocational high school were involved to receive a 10 learning session about peace and media literacy. The aggression questionnaire was used to identify participants, supported by student’s record in school. To collect data, the questionnaire for measuring understanding about aggression has been developed and was used after the validity and reliability of this questionnaire tested. Post-test was carried out after the session ended. Data were analyzed using t-test. The finding result showed that the mean score of student’s understanding of aggression was increased, therefore learning session of peace education and media literacy is significantly effective to enhance student’s understanding of aggression. It also showed a meaningful difference of understanding between male and female student’s whereas female students have a better understanding of aggression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aggressive%20behavior%20prevention" title="aggressive behavior prevention">aggressive behavior prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=aggression" title=" aggression"> aggression</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20literacy" title=" media literacy"> media literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=peace%20education" title=" peace education"> peace education</a>, <a href="https://publications.waset.org/abstracts/search?q=peacebuilding" title=" peacebuilding"> peacebuilding</a> </p> <a href="https://publications.waset.org/abstracts/86385/aggressive-behavior-prevention-the-effect-of-peace-education-and-media-literacy-towards-students-understanding-about-aggression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86385.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">179</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">106</span> Comparative Study od Three Artificial Intelligence Techniques for Rain Domain in Precipitation Forecast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabilah%20Filzah%20Mohd%20Radzuan">Nabilah Filzah Mohd Radzuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Andi%20Putra"> Andi Putra</a>, <a href="https://publications.waset.org/abstracts/search?q=Zalinda%20Othman"> Zalinda Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Azuraliza%20Abu%20Bakar"> Azuraliza Abu Bakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Razak%20Hamdan"> Abdul Razak Hamdan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Precipitation forecast is important to avoid natural disaster incident which can cause losses in the involved area.

Using a threshold creep law for composite materials, expressions for stresses, strains, and strain rates are derived for several anisotropic cases.

Since for a specific type of material anisotropy described in the paper, these quantities are found to have the lowest values at the inner radius (the potential location of cylinder failure), it is concluded that by employing such an anisotropic material for the design of a thick-walled cylinder a longer service life for the cylinder may be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creep" title="creep">creep</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20strains" title=" large strains"> large strains</a>, <a href="https://publications.waset.org/abstracts/search?q=thick-walled%20cylinders" title=" thick-walled cylinders"> thick-walled cylinders</a>, <a href="https://publications.waset.org/abstracts/search?q=anisotropy" title=" anisotropy"> anisotropy</a> </p> <a href="https://publications.waset.org/abstracts/165479/large-strain-creep-analysis-of-composite-thick-walled-anisotropic-cylinders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165479.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">149</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">104</span> Novel Aminoglycosides to Target Resistant Pathogens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihar%20Ranjan">Nihar Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Derrick%20Watkins"> Derrick Watkins</a>, <a href="https://publications.waset.org/abstracts/search?q=Dev%20P.%20Arya"> Dev P.

We have developed novel high-throughput capable assays for ribosome targeted drug discovery. One such assay examines the compounds ability to bind to a model ribosomal RNA A-site. We have also coupled this assay to other functional orthogonal assays. Such analysis can provide valuable understanding of the relationships between two complementary drug screening methods and could be used as standard analysis to correlate the affinity of a compound for its target and the effect the compound has on a cell. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20resistance" title="bacterial resistance">bacterial resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=aminoglycosides" title=" aminoglycosides"> aminoglycosides</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a>, <a href="https://publications.waset.org/abstracts/search?q=drugs" title=" drugs"> drugs</a> </p> <a href="https://publications.waset.org/abstracts/16341/novel-aminoglycosides-to-target-resistant-pathogens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16341.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">370</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">103</span> Gall Bladder Polyp Identified as Solitary RCC Metastasis 4 Years after Nephrectomy: An Unusual Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerard%20Bray">Gerard Bray</a>, <a href="https://publications.waset.org/abstracts/search?q=Arya%20Bahadori"> Arya Bahadori</a>, <a href="https://publications.waset.org/abstracts/search?q=Sachinka%20Ranasinghe"> Sachinka Ranasinghe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Renal cell carcinoma (RCC) is among the top 10 most common cancers worldwide, where metastatic disease carries a poor prognosis. Herein, we present a 74-year-old male presenting with asymptomatic solitary metachronous metastasis to the gall bladder 4 years following nephrectomy for clear cell RCC. Solitary RCC metastasis to the gall bladder following nephrectomy is rarely reported in the literature and brings with it a clinical conundrum of whether surgical resection or systemic therapy should be utilized. In this case, surgical excision with cholecystectomy was employed without systemic therapy. We, therefore, contribute a rare and interesting case that highlights that metastasectomy of a solitary metastasis can improve survival according to current literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renal%20cell%20carcinoma" title="renal cell carcinoma">renal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=gall%20bladder%20metastasis" title=" gall bladder metastasis"> gall bladder metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=solitary%20metastasectomy" title=" solitary metastasectomy"> solitary metastasectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=metachronous" title=" metachronous"> metachronous</a> </p> <a href="https://publications.waset.org/abstracts/145137/gall-bladder-polyp-identified-as-solitary-rcc-metastasis-4-years-after-nephrectomy-an-unusual-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145137.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">173</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">102</span> Design of Ternary Coatings System to Minimize the Residual Solvent in Polymeric Coatings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyoti%20Sharma">Jyoti Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumar%20Arya"> Raj Kumar Arya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The coatings of homogeneous ternary solution of Poly(styrene)(PS)-Poly(ethyleneglycol)-6000(PEG) Chlorobenzene (CLB) of two different concentrations (5.05%-4.98%-89.97% and 10.05%-5.12%-84.82%) were studied and dried under quiescent conditions.

Cryptographic algorithms scramble the data so that intruder will not able to retrieve it; however steganography covers that data in some cover file so that presence of communication is hidden. This paper presents the implementation of Ron Rivest, Adi Shamir, and Leonard Adleman (RSA) Algorithm with Image and Audio Steganography and Data Encryption Standard (DES) Algorithm with Image and Audio Steganography. The coding for both the algorithms have been done using MATLAB and its observed that these techniques performed better than individual techniques. The risk of unauthorized access is alleviated up to a certain extent by using these techniques. These techniques could be used in Banks, RAW agencies etc, where highly confidential data is transferred.
