This study attempts to do empirical approach between specific technologies’ classification. For technological convergence classification, it is necessary to set the target technology to be analyzed. This study selected target technology from national research and development plan. At first we found a source technology for analysis. Depending on the weight of source technology, NT-based, BT-based, IT-based, ET-based, CS-based convergence types were classified. This study aims to empirically show the concept of convergence technology and convergence types. If we use the source technology to classify convergence type, it will be useful to make practical strategies of convergence technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technology%20convergence" title="technology convergence">technology convergence</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20technology" title=" source technology"> source technology</a>, <a href="https://publications.waset.org/abstracts/search?q=convergence%20type" title=" convergence type"> convergence type</a>, <a href="https://publications.waset.org/abstracts/search?q=R%26D%20strategy" title=" R&D strategy"> R&D strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20classification" title=" technology classification"> technology classification</a> </p> <a href="https://publications.waset.org/abstracts/37117/a-research-analysis-on-the-source-technology-and-convergence-types" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37117.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">485</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">11871</span> Development of Open Source Geospatial Certification Model Based on Geospatial Technology Competency Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanzeel%20Ur%20Rehman%20Khan">Tanzeel Ur Rehman Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Franz%20Josef%20Behr"> Franz Josef Behr</a>, <a href="https://publications.waset.org/abstracts/search?q=Phillip%20Davis"> Phillip Davis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Open source geospatial certifications are needed in geospatial technology education and industry sector. In parallel with proprietary software, free and open source software solutions become important in geospatial technology research and play an important role for the growth of the geospatial industry. ESRI, GISCI (GIS Certification Institute), ASPRS (American Society of Photogrammetry and remote sensing), and Meta spatial are offering certifications on proprietary and open source software. These are portfolio and competency based certifications depending on GIS Body of Knowledge (Bok). The analysis of these certification approaches might lead to the discovery of some gaps in them and will open a new way to develop certifications related to the geospatial open source (OS). This new certification will investigate the different geospatial competencies according to open source tools that help to identify geospatial professionals and strengthen the geospatial academic content. The goal of this research is to introduce a geospatial certification model based on geospatial technology competency model (GTCM).The developed certification will not only incorporate the importance of geospatial education and production of the geospatial competency-based workforce in universities and companies (private or public) as well as describe open source solutions with tools and technology. Job analysis, market analysis, survey analysis of this certification opens a new horizon for business as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geospatial%20certification" title="geospatial certification">geospatial certification</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source" title=" open source"> open source</a>, <a href="https://publications.waset.org/abstracts/search?q=geospatial%20technology%20competency%20model" title=" geospatial technology competency model"> geospatial technology competency model</a>, <a href="https://publications.waset.org/abstracts/search?q=geoscience" title=" geoscience"> geoscience</a> </p> <a href="https://publications.waset.org/abstracts/33486/development-of-open-source-geospatial-certification-model-based-on-geospatial-technology-competency-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33486.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">566</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">11870</span> Conceptualization and Strategies of Biogas Technology for Rural Development in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Okorowo%20Cyril%20Agochi">Okorowo Cyril Agochi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main challenge of present world is to harness the energy source which is environment friendly and ecologically balanced. This need has forced to search for other alternate source of energy. But unfortunately the new alternative energy sources like the solar, hydro, wind etc. require huge economical value and technical power to operate, which seem to be very difficult for the developing countries like Nigeria. In the present moment biogas energy can be one and only reliable, easily available and economically feasible source of alternative and renewable source which can be managed by locally available sources and simple technology for secondary schools, tertiary institution and rural villages.

However, this information can be compromised in many cases, such as when it is stored locally on the company's computers or when it is transferred between servers and clients. Of these important information leaks, source code leaks are probably the most costly. Because the source code often represents the core technology of the company, especially for the Internet companies, source code leakage may even lead to the company's core products lose market competitiveness, and then lead to the bankruptcy of the company. In recent years, such as Microsoft, AMD and other large companies have occurred source code leakage events, suffered a huge loss. This reveals to us the importance and necessity of preventing source code leakage. This paper aims to find ways to prevent source code leakage based on the direction of operating system, and based on the fact that most companies use Linux or Linux-like system to realize the interconnection between server and client, to discuss how to reduce the possibility of source code leakage during data transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20transmission" title="data transmission">data transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=Linux" title=" Linux"> Linux</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20code" title=" source code"> source code</a>, <a href="https://publications.waset.org/abstracts/search?q=operating%20system" title=" operating system"> operating system</a> </p> <a href="https://publications.waset.org/abstracts/153161/unix-source-code-leak-evaluation-and-feasible-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153161.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">270</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">11868</span> Patent License of Transfer Technology: Challenges and Opportunities in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agung%20Sujatmiko">Agung Sujatmiko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the purposes of patent licensing was to transfer technology from developed countries to developing countries. For this reason, the role of the patent license agreement was very important and had a function as a tool to achieve technological development. This goal was very good, but in fact, many problems and obstacles arose in its implementation, so the technology transfer that had been implemented had not given good results. For this reason, it was necessary to find a solution so that technology could switch properly. The problem approach used the statutory and conceptual approaches. The analysis used was deductive by analyzing general laws and regulations and then concluding. Several regulations related to technology transfer were the main source to find answers to why technology transfer was difficult to achieve and what caused it. Once the cause was known, a solution would be sought. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=license" title="license">license</a>, <a href="https://publications.waset.org/abstracts/search?q=patent" title=" patent"> patent</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=tie%20in%20clause" title=" tie in clause"> tie in clause</a> </p> <a href="https://publications.waset.org/abstracts/168971/patent-license-of-transfer-technology-challenges-and-opportunities-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168971.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">95</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">11867</span> Use of Magnesium as a Renewable Energy Source</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafayel%20K.%20Kostanyan">Rafayel K.

Due to the inherent nature of open source development, a specific set of open source software development practices has evolved. While there is an ongoing research on the topic of applicability of open source development practices within a company setting, still little is known about their benefits and challenges. The objective of this research is to understand if and to what degree open source development practices observed within a mature open source community are aligned with development practices within a large software and hardware company setting. For the purpose of this case study a set of open source development practices that are present in a mature open source community has been identified. Then, development practices of a large, international, hardware and software company based in Sweden were assessed and compared to the identified open source community practices. It is shown that there are many similarities between a mature open source community and a large company setting in regard to software development practices. We also identify practices that exist in open source communities and that are not standard within a company setting, but whose implementation can result in an improved software development efficiency within the company setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development%20practices" title="development practices">development practices</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20software" title=" open source software"> open source software</a>, <a href="https://publications.waset.org/abstracts/search?q=innersource" title=" innersource"> innersource</a>, <a href="https://publications.waset.org/abstracts/search?q=closed%20open%20source" title=" closed open source"> closed open source</a> </p> <a href="https://publications.waset.org/abstracts/13154/a-case-study-of-open-source-development-practices-within-a-large-company-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13154.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">558</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">11865</span> Investigation on Biomass as an Alternate Source for Power Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narsimhulu%20Sanke">Narsimhulu Sanke</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20N.%20Reddy"> D.

The results show that the mismatch between the goal and the source is not entirely rooted in non-linguistic behaviors, i.e. that linguistic descriptions also show the focus of the goal on the source in events; Non-verbal memory for events, on the other hand, indicates that the focus of the goal is only on events that are purposefully moving and the actor is alive. In the present study, an attempt is made to examine the principle of priority of the goal over the source by focusing on Persian directional motion verbs. For this purpose, 117 Persian directional motion verbs have been selected from the dictionary and data for them have been collected from the body of Bijan Khan and the components of goal and source have been identified in sentences and the prominence of the components of goal and source has been shown in the form of diagrams. As it was obtained from the data, Persian motion-directional verbs also showed the bias of the goal over source in motion events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motion-directional%20verbs" title="motion-directional verbs">motion-directional verbs</a>, <a href="https://publications.waset.org/abstracts/search?q=priority%20of%20goal%20over%20source%20principle" title=" priority of goal over source principle"> priority of goal over source principle</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20factors" title=" cognitive factors"> cognitive factors</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20factors" title=" linguistic factors"> linguistic factors</a> </p> <a href="https://publications.waset.org/abstracts/156958/priority-of-goal-over-source-in-persian-directional-motion-verbs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156958.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">87</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">11863</span> The Evaluation Model for the Quality of Software Based on Open Source Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Donghong">Li Donghong</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng%20Fuyang"> Peng Fuyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Guanghua"> Yang Guanghua</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Xiaoyan"> Su Xiaoyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using open source code is a popular method of software development.

In this work performance analysis of ORC is conducted based on the second law of thermodynamics for recovery of low temperature heat source from 100°C to 140°C using R134a as the working fluid. Effects of system parameters such as turbine inlet pressure or source temperature are theoretically investigated on the exergy destructions (anergies) at various components of the system as well as net work production or exergy efficiency. Results show that the net work or exergy efficiency has a peak with respect to the turbine inlet pressure when the source temperature is low, however, increases monotonically with increasing turbine inlet pressure when the source temperature is high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Organic%20Rankine%20Cycle%20%28ORC%29" title="Organic Rankine Cycle (ORC)">Organic Rankine Cycle (ORC)</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20temperature%20heat%20source" title=" low temperature heat source"> low temperature heat source</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy" title=" exergy"> exergy</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20temperature" title=" source temperature "> source temperature </a> </p> <a href="https://publications.waset.org/abstracts/8156/a-second-law-assessment-of-organic-rankine-cycle-depending-on-source-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8156.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">452</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">11861</span> GA3C for Anomalous Radiation Source Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Yi%20Liu">Chia-Yi Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo-Bin%20Xiao"> Bo-Bin Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Bin%20Lin"> Wen-Bin Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsiang-Ning%20Wu"> Hsiang-Ning Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang-Hsun%20Huang"> Liang-Hsun Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to reduce the risk of radiation damage that personnel may suffer during operations in the radiation environment, the use of automated guided vehicles to assist or replace on-site personnel in the radiation environment has become a key technology and has become an important trend. In this paper, we demonstrate our proof of concept for autonomous self-learning radiation source searcher in an unknown environment without a map. The research uses GPU version of Asynchronous Advantage Actor-Critic network (GA3C) of deep reinforcement learning to search for radiation sources. The searcher network, based on GA3C architecture, has self-directed learned and improved how search the anomalous radiation source by training 1 million episodes under three simulation environments. In each episode of training, the radiation source position, the radiation source intensity, starting position, are all set randomly in one simulation environment. The input for searcher network is the fused data from a 2D laser scanner and a RGB-D camera as well as the value of the radiation detector. The output actions are the linear and angular velocities. The searcher network is trained in a simulation environment to accelerate the learning process. The well-performance searcher network is deployed to the real unmanned vehicle, Dashgo E2, which mounts LIDAR of YDLIDAR G4, RGB-D camera of Intel D455, and radiation detector made by Institute of Nuclear Energy Research. In the field experiment, the unmanned vehicle is enable to search out the radiation source of the 18.5MBq Na-22 by itself and avoid obstacles simultaneously without human interference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20reinforcement%20learning" title="deep reinforcement learning">deep reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=GA3C" title=" GA3C"> GA3C</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20searching" title=" source searching"> source searching</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20detection" title=" source detection"> source detection</a> </p> <a href="https://publications.waset.org/abstracts/148264/ga3c-for-anomalous-radiation-source-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148264.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">114</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">11860</span> The Exploration Targets of the Nanpu Sag: Insight from Organic Geochemical Characteristics of Source Rocks and Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lixin%20Pei">Lixin Pei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhilong%20Huang"> Zhilong Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenzhe%20Gang"> Wenzhe Gang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organic geochemistry of source rocks and oils in the Nanpu Sag, Bohai Bay basin was studied on the basis of the results of Rock-Eval and biomarker. The possible source rocks consist of the third member (Es₃) and the first member (Es₁) of Shahejie formation and the third member of Dongying Formation (Ed₃) in the Nanpu Sag. The Es₃, Es₁, and Ed₃ source rock intervals in the Nanpu Sag all have high organic-matter richness and are at hydrocarbon generating stage, which are regarded as effective source rocks. The three possible source rock intervals have different biomarker associations and can be differentiated by gammacerane/αβ C₃₀ hopane, ETR ([C₂₈+C₂₉]/ [C₂₈+C₂₉+Ts]), C₂₇ diasterane/sterane and C₂₇/C₂₉ steranes, which suggests they deposited in different environments. Based on the oil-source rock correlation, the shallow oils mainly originated from the Es₃ and Es₁ source rocks in the Nanpu Sag. Through hydrocarbon generation and expulsion history of the source rocks, trap development history and accumulation history, the shallow oils mainly originated from paleo-reservoirs in the Es₃ and Es₁ during the period of Neotectonism, and the residual paleo-reservoirs in the Es₃ and Es₁ would be the focus targets in the Nanpu Sag; Bohai Bay Basin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=source%20rock" title="source rock">source rock</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker%20association" title=" biomarker association"> biomarker association</a>, <a href="https://publications.waset.org/abstracts/search?q=Nanpu%20Sag" title=" Nanpu Sag"> Nanpu Sag</a>, <a href="https://publications.waset.org/abstracts/search?q=Bohai%20Bay%20Basin" title=" Bohai Bay Basin"> Bohai Bay Basin</a> </p> <a href="https://publications.waset.org/abstracts/79990/the-exploration-targets-of-the-nanpu-sag-insight-from-organic-geochemical-characteristics-of-source-rocks-and-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79990.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">373</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">11859</span> An Introductory Study on Optimization Algorithm for Movable Sensor Network-Based Odor Source Localization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yossiri%20Ariyakul">Yossiri Ariyakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Piyakiat%20Insom"> Piyakiat Insom</a>, <a href="https://publications.waset.org/abstracts/search?q=Poonyawat%20Sangiamkulthavorn"> Poonyawat Sangiamkulthavorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Takamichi%20Nakamoto"> Takamichi Nakamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the method of optimization algorithm for sensor network comprised of movable sensor nodes which can be used for odor source localization was proposed.

EXVol is possible to describe the source area as a non-uniform three-dimensional (x, y, z) source. And decompose and set it into several sets of volume units. Users can equally divide (x, y, z) coordinate system to calculate the detection efficiency at a specific position of a cylindrical volume source. By determining the detection efficiency for differential volume units, the total radiative absolute distribution and the correction factor of the detection efficiency can be obtained from the nondestructive measurement of the source. In order to check the performance of the EXVol code, Si ingot of 20 cm in diameter and 50 cm in height were used as a source. The detector was moved at the collimation geometry to calculate the detection efficiency at a specific position and compared with the experimental values. In this study, the performance of the EXVol code was extended to obtain the detection efficiency distribution at a specific position in a large volume source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attenuation" title="attenuation">attenuation</a>, <a href="https://publications.waset.org/abstracts/search?q=EXVol" title=" EXVol"> EXVol</a>, <a href="https://publications.waset.org/abstracts/search?q=detection%20efficiency" title=" detection efficiency"> detection efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20source" title=" volume source"> volume source</a> </p> <a href="https://publications.waset.org/abstracts/97158/calculation-of-detection-efficiency-of-horizontal-large-volume-source-using-exvol-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97158.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">185</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">11856</span> Analysis of Joint Source Channel LDPC Coding for Correlated Sources Transmission over Noisy Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Ben%20Abdessalem">Marwa Ben Abdessalem</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Zribi"> Amin Zribi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Bouall%C3%A8gue"> Ammar Bouallègue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a Joint Source Channel coding scheme based on LDPC codes is investigated. We consider two concatenated LDPC codes, one allows to compress a correlated source and the second to protect it against channel degradations. The original information can be reconstructed at the receiver by a joint decoder, where the source decoder and the channel decoder run in parallel by transferring extrinsic information. We investigate the performance of the JSC LDPC code in terms of Bit-Error Rate (BER) in the case of transmission over an Additive White Gaussian Noise (AWGN) channel, and for different source and channel rate parameters. We emphasize how JSC LDPC presents a performance tradeoff depending on the channel state and on the source correlation. We show that, the JSC LDPC is an efficient solution for a relatively low Signal-to-Noise Ratio (SNR) channel, especially with highly correlated sources. Finally, a source-channel rate optimization has to be applied to guarantee the best JSC LDPC system performance for a given channel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AWGN%20channel" title="AWGN channel">AWGN channel</a>, <a href="https://publications.waset.org/abstracts/search?q=belief%20propagation" title=" belief propagation"> belief propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20source%20channel%20coding" title=" joint source channel coding"> joint source channel coding</a>, <a href="https://publications.waset.org/abstracts/search?q=LDPC%20codes" title=" LDPC codes"> LDPC codes</a> </p> <a href="https://publications.waset.org/abstracts/62721/analysis-of-joint-source-channel-ldpc-coding-for-correlated-sources-transmission-over-noisy-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62721.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">357</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">11855</span> Assessment of the Contribution of Geographic Information System Technology in Non Revenue Water: Case Study Dar Es Salaam Water and Sewerage Authority Kawe - Mzimuni Street</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Pesco%20Kassa">Victor Pesco Kassa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research deals with the assessment of the contribution of GIS Technology in NRW.

The results show that the source temperature as well as the ammonia mass fraction affects greatly on the thermodynamic performance of the cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ammonia-water%20mixture" title="ammonia-water mixture">ammonia-water mixture</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalina%20cycle" title=" Kalina cycle"> Kalina cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=low-grade%20heat%20source" title=" low-grade heat source"> low-grade heat source</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20temperature" title=" source temperature"> source temperature</a> </p> <a href="https://publications.waset.org/abstracts/22703/performance-analysis-of-absorption-power-cycle-under-different-source-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22703.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">458</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">11851</span> Requirement Engineering Within Open Source Software Development: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kars%20Beek">Kars Beek</a>, <a href="https://publications.waset.org/abstracts/search?q=Remco%20Groeneveld"> Remco Groeneveld</a>, <a href="https://publications.waset.org/abstracts/search?q=Sjaak%20Brinkkemper"> Sjaak Brinkkemper</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although there is much literature available on requirement documentation in traditional software development, few studies have been conducted about this topic in open source software development. While open-source software development is becoming more important, the software development processes are often not as structured as corporate software development processes. Papers show that communities, creating open-source software, often lack structure and documentation. However, most recent studies about this topic are often ten or more years old. Therefore, this research has been conducted to determine if the lack of structure and documentation in requirement engineering is currently still the situation in these communities. Three open-source products have been chosen as subjects for conducting this research. The data for this research was gathered based on interviews, observations, and analyses of feature proposals and issue tracking tools. In this paper, we present a comparison and an analysis of the different methods used for requirements documentation to understand the current practices of requirements documentation in open source software development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=case%20study" title="case study">case study</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20software" title=" open source software"> open source software</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20software%20development" title=" open source software development"> open source software development</a>, <a href="https://publications.waset.org/abstracts/search?q=requirement%20elicitation" title=" requirement elicitation"> requirement elicitation</a>, <a href="https://publications.waset.org/abstracts/search?q=requirement%20engineering" title=" requirement engineering"> requirement engineering</a> </p> <a href="https://publications.waset.org/abstracts/143917/requirement-engineering-within-open-source-software-development-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143917.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">104</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">11850</span> Victims and Violators: Open Source Information, Admissibility Standards, and War Crimes Investigations in Iraq and Syria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Genevieve%20Zingg">Genevieve Zingg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern technology and social media platforms have fundamentally altered the nature of war crimes investigations by providing new forms of data, evidence, and documentation, and pose a unique opportunity to expand the efficacy of international law. However, much of the open source information available is deemed inadmissible in subsequent legal proceedings and fails to function as evidence largely due to issues of reliability and verifiability. Focusing on current judicial investigations related to ongoing conflicts in Syria and Iraq, this paper will examine key challenges and opportunities for the effective use of open source information in securing justice. This paper will consider strategies and approaches that can be used to ensure that information collected by affected populations meets basic admissibility standards. This paper argues that the critical failure to equip civilian populations in conflict zones with knowledge and information regarding established admissibility standards and guidelines both jeopardizes the potential of open source information and compromises the ability of victims to participate effectively in justice and accountability processes. The ultimate purpose of this paper is, therefore, to examine how to maximize the value of open source information based on the rules of evidence in international, regional, and national courts, and how to maximize the participation of affected populations in holding their abusers to account. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title="human rights">human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20criminal%20law" title=" international criminal law"> international criminal law</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20justice" title=" international justice"> international justice</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20law" title=" international law"> international law</a>, <a href="https://publications.waset.org/abstracts/search?q=Iraq" title=" Iraq"> Iraq</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20information" title=" open source information"> open source information</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=Syria" title=" Syria"> Syria</a>, <a href="https://publications.waset.org/abstracts/search?q=transitional%20justice" title=" transitional justice"> transitional justice</a>, <a href="https://publications.waset.org/abstracts/search?q=war%20crimes" title=" war crimes"> war crimes</a> </p> <a href="https://publications.waset.org/abstracts/85349/victims-and-violators-open-source-information-admissibility-standards-and-war-crimes-investigations-in-iraq-and-syria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85349.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11849</span> Determinants of Rural Household Effective Demand for Biogas Technology in Southern Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mesfin%20Nigussie">Mesfin Nigussie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objectives of the study were to identify factors affecting rural households’ willingness to install biogas plant and amount willingness to pay in order to examine determinants of effective demand for biogas technology. A multistage sampling technique was employed to select 120 respondents for the study. The binary probit regression model was employed to identify factors affecting rural households’ decision to install biogas technology. The probit model result revealed that household size, total household income, access to extension services related to biogas, access to credit service, proximity to water sources, perception of households about the quality of biogas, perception index about attributes of biogas, perception of households about installation cost of biogas and availability of energy source were statistically significant in determining household’s decision to install biogas. Tobit model was employed to examine determinants of rural household’s amount of willingness to pay. Based on the model result, age of the household head, total annual income of the household, access to extension service and availability of other energy source were significant variables that influence willingness to pay. Providing due considerations for extension services, availability of credit or subsidy, improving the quality of biogas technology design and minimizing cost of installation by using locally available materials are the main suggestions of this research that help to create effective demand for biogas technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas%20technology" title="biogas technology">biogas technology</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20demand" title=" effective demand"> effective demand</a>, <a href="https://publications.waset.org/abstracts/search?q=probit%20model" title=" probit model"> probit model</a>, <a href="https://publications.waset.org/abstracts/search?q=tobit%20model" title=" tobit model"> tobit model</a>, <a href="https://publications.waset.org/abstracts/search?q=willingnes%20to%20pay" title=" willingnes to pay"> willingnes to pay</a> </p> <a href="https://publications.waset.org/abstracts/108948/determinants-of-rural-household-effective-demand-for-biogas-technology-in-southern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108948.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">11848</span> Use of Cow Dung Residues of Biogas Plants for Sustainable Development of Rural Communities in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumra%20Siddique%20Abbasi">Sumra Siddique Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Shikun"> Cheng Shikun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biogas technology has rapidly developed in agriculture sector to upgrade and improve the life of farmers by providing them alternative and cost-effective energy source.

This can provide additional information in the absence of optical equipment. The purpose of this study is to estimate Direction of Arrival (DOA) based on Time Difference of Arrival (TDOA) estimation of the acoustic source in the drone. The problem is that it is impossible to measure the clear target acoustic source because of the drone noise. To overcome this problem is to separate the drone noise and the target acoustic source using Blind Source Separation(BSS) based on Independent Component Analysis(ICA). ICA can be performed assuming that the drone noise and target acoustic source are independent and each signal has non-gaussianity. For maximized non-gaussianity each signal, we use Negentropy and Kurtosis based on probability theory. As a result, we can improve TDOA estimation and DOA estimation of the target source in the noisy environment. We simulated the performance of the DOA algorithm applying BSS algorithm, and demonstrated the simulation through experiment at the anechoic wind tunnel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeroacoustics" title="aeroacoustics">aeroacoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=acoustic%20source%20detection" title=" acoustic source detection"> acoustic source detection</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20difference%20of%20arrival" title=" time difference of arrival"> time difference of arrival</a>, <a href="https://publications.waset.org/abstracts/search?q=direction%20of%20arrival" title=" direction of arrival"> direction of arrival</a>, <a href="https://publications.waset.org/abstracts/search?q=blind%20source%20separation" title=" blind source separation"> blind source separation</a>, <a href="https://publications.waset.org/abstracts/search?q=independent%20component%20analysis" title=" independent component analysis"> independent component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=drone" title=" drone"> drone</a> </p> <a href="https://publications.waset.org/abstracts/94236/study-on-acoustic-source-detection-performance-improvement-of-microphone-array-installed-on-drones-using-blind-source-separation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94236.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">162</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">11845</span> Fuzzy Optimization Multi-Objective Clustering Ensemble Model for Multi-Source Data Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20B.%20Le">C.

Multi-source data clustering has emerged as a important issue in the data mining and machine learning community. Different data sources provide information about different data. Therefore, multi-source data linking is essential to improve clustering performance. However, in practice multi-source data is often heterogeneous, uncertain, and large. This issue is considered a major challenge from multi-source data. Ensemble is a versatile machine learning model in which learning techniques can work in parallel, with big data. Clustering ensemble has been shown to outperform any standard clustering algorithm in terms of accuracy and robustness. However, most of the traditional clustering ensemble approaches are based on single-objective function and single-source data. This paper proposes a new clustering ensemble method for multi-source data analysis. The fuzzy optimized multi-objective clustering ensemble method is called FOMOCE. Firstly, a clustering ensemble mathematical model based on the structure of multi-objective clustering function, multi-source data, and dark knowledge is introduced. Then, rules for extracting dark knowledge from the input data, clustering algorithms, and base clusterings are designed and applied. Finally, a clustering ensemble algorithm is proposed for multi-source data analysis. The experiments were performed on the standard sample data set. The experimental results demonstrate the superior performance of the FOMOCE method compared to the existing clustering ensemble methods and multi-source clustering methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clustering%20ensemble" title="clustering ensemble">clustering ensemble</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-source" title=" multi-source"> multi-source</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-objective" title=" multi-objective"> multi-objective</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20clustering" title=" fuzzy clustering"> fuzzy clustering</a> </p> <a href="https://publications.waset.org/abstracts/136598/fuzzy-optimization-multi-objective-clustering-ensemble-model-for-multi-source-data-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136598.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">189</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">11844</span> Relevance of Technology on Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felicia%20K.%20Oluwalola">Felicia K.

In the existing block bundle adjustment methods, as the controlling information in the adjustment system, the approach using single observation scale and precision is unable to screen out the control information and to give reasonable and effective corresponding weights, which reduces the convergence and adjustment reliability of the results. Referring to the relevant theory and technology of quotient space, in this project, several subjects are researched. Multi-layer quotient space of multi-geometric features is constructed to describe and filter control data. Normalized granularity merging mechanism of multi-layer control information is studied and based on the normalized scale factor, the strategy to optimize the weight selection of control data which is less relevant to the adjustment system can be realized. At the same time, geometric positioning experiment is conducted using multi-source remote sensing data, aerial images, and multiclass control data to verify the theoretical research results. This research is expected to break through the cliché of the single scale and single accuracy control data in the adjustment process and expand the theory and technology of photogrammetry. Thus the problem to process multi-source remote sensing data will be solved both theoretically and practically. <p class="card-text"><strong>Keywords:</strong> <a
