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">3228</span> Production Radionuclide Therapy 161-Terbium Using by Talys1.6 and Empire 3.2 Codes in Reactions Cyclotron</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shohreh%20Rahimi%20Lascokalayeh">Shohreh Rahimi Lascokalayeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Yousefnia"> Hasan Yousefnia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Tajik"> Mojtaba Tajik</a>, <a href="https://publications.waset.org/abstracts/search?q=Samaneh%20Zolghadri"> Samaneh Zolghadri</a>, <a href="https://publications.waset.org/abstracts/search?q=Bentehoda%20Abdolhosseini"> Bentehoda Abdolhosseini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the production of terbium-161 as new therapeutic radionuclide was investigated using TALYS1.6& EMPIRE 3.2 codes.

Every crisis situations and perils has an origin in the emergency/ crisis event occurrence and they need critical/ crisis interfaces assessment. Here, the emergency events can be expected - then crisis scenarios can be pre-prepared by pertinent organizational crisis management authorities towards their coping; or it may be unexpected - without pre-prepared scenario of event. But the both need operational coping by means of crisis management as well. The operation, forms, characteristics, behaviour and utilization of crisis management have various qualities, depending on real critical infrastructure organization perils, and prevention training processes. An aim is always - better security and continuity of the organization, which successful obtainment needs to find and investigate critical/ crisis zones and functions in critical infrastructure organization models, operating in pertinent perils environment. Our DYVELOP (Dynamic Vector Logistics of Processes) method is disposables for it. Here, it is necessary to derive and create identification algorithm of critical/ crisis interfaces. The locations of critical/ crisis interfaces are the flags of crisis situation in organization of critical infrastructure models. Then, the model of crisis situation will be displayed at real organization of Czech energetic crisis infrastructure subject in real peril environment. These efficient measures are necessary for the infrastructure protection. They will be derived for peril mitigation, crisis situation coping and for environmentally friendly organization survival, continuity and its sustainable development advanced possibilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algorithms" title="algorithms">algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=energetic%20infrastructure%20complex%20system" title=" energetic infrastructure complex system"> energetic infrastructure complex system</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=peril%C2%B4s%20environment" title=" peril´s environment"> peril´s environment</a> </p> <a href="https://publications.waset.org/abstracts/39510/perils-environment-of-energetic-infrastructure-complex-system-modelling-by-the-crisis-situation-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39510.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">402</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">3226</span> Code Switching and Language Attitudes of Two 10-11 Years Old Bilingual Child</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kristiina%20Teiss">Kristiina Teiss</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Estonians and children having Estonian as a one of their languages have lately become the fastest growing minority or bilingual group in Finland which underlines the importance of studying this target group. The acquisition of bilingualism by an infant is affected by many different issues like the child’s personal traits, language differences, and different environmental factors such as people´s attitudes towards languages and bilingualism. In the early years the most important factor is the children’s interaction with their parents and siblings. This poster gives an overview to the material and some preliminary findings of ongoing PhD study concerning code-mixing, code-switching and language attitudes of two bilingual 10-11 year old children. Data was collected from two different bilingual families, one of them living in Tampere, Finland and one of them moved during the study to Tallinn, Estonia. The data includes audio recordings of the families’ interactions with their children when they were aged 2-3 years old and then when they were 10-11 years old. The data also includes recorded semi-structured queries of the parents, as well as recorded semi-structured queries of the children when they were in the age of 10-11 years. The features of code-mixing can vary depending on norms or models in the families, or even according to its use by two parents in same family. The practices studied in the ongoing longitudinal case study, based on a framework of ethnography, contain parental conversational strategies and family attitudes as well as CS (code-switching and code-mixing) cases occurring both in children and adult language. The aim of this paper is to find out whether there is a connection between children’s attitudes and their daily language use. It would be also interesting to find some evidence, as to whether living in different countries has different impacts on using two languages. The results of dissertation maid give some directional suggestions on how language maintenance of Estonian-Finnish bilinguals could be supported, although generalizations on the base of case study could not be done. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=code%20switching" title="code switching">code switching</a>, <a href="https://publications.waset.org/abstracts/search?q=Estonian" title=" Estonian"> Estonian</a>, <a href="https://publications.waset.org/abstracts/search?q=Finnish" title=" Finnish"> Finnish</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20attitudes" title=" language attitudes "> language attitudes </a> </p> <a href="https://publications.waset.org/abstracts/38639/code-switching-and-language-attitudes-of-two-10-11-years-old-bilingual-child" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38639.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">371</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">3225</span> Quick Response Codes in Physio: A Simple Click to Long-Term Oxygen Therapy Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20W.%20Lee">K.

It enables users to open websites, photos and other information with mobile devices by just snapping the code. In usual Long Term Oxygen Therapy arrangement, piles of LTOT related information like leaflets from different oxygen service providers are given to patients to choose an appropriate plan according to their needs. If these printed materials are transformed into electronic format (QR Code), it would be more environmentally-friendly. More importantly, electronic materials including LTOT equipment operation and dyspnoea relieving techniques also empower patients in long-term disease management. The objective to this study is to investigate the effect of QR code in patient education on new LTOT users. This study was carried out in medical wards of North District Hospital. Adult patients and relatives who followed commands, were able to use smartphones with internet services and required LTOT arrangement on hospital discharge were recruited. In LTOT arrangement, apart from the usual LTOT education booklets which included patients’ personal information (e.g. oxygen titration and six-minute walk test results etc.), extra leaflets consisted of 1. QR codes of LTOT plans from different oxygen service providers, 2. Education materials of dyspnoea management and 3. Instructions on LTOT equipment operation were given. Upon completion of LTOT arrangement, a questionnaire about the use of QR code on patient education was filled in by patients or relatives. A total of 10 new LTOT users were recruited from November 2017 to January 2018. Initially, 70% of them did not know anything about the QR code, but all of them understood its operation after a simple demonstration. 70% of them agreed that it was convenient to use (20% strongly agree, 40% agree, 10% somewhat agree). 80% of them agreed that QR code could facilitate the retrieval of more LTOT related information (10% strongly agree, 70% agree) while 90% agreed that we should continue delivering QR code leaflets to new LTOT users in the future (30% strongly agree, 40% agree, 20% somewhat agree). It is proven that QR code is a convenient and environmentally-friendly tool to deliver information. It is also relatively easy to be introduced to new users. It has received welcoming feedbacks from current users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=long-term%20oxygen%20therapy" title="long-term oxygen therapy">long-term oxygen therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=physiotherapy" title=" physiotherapy"> physiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20education" title=" patient education"> patient education</a>, <a href="https://publications.waset.org/abstracts/search?q=QR%20code" title=" QR code"> QR code</a> </p> <a href="https://publications.waset.org/abstracts/95306/quick-response-codes-in-physio-a-simple-click-to-long-term-oxygen-therapy-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95306.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">148</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">3224</span> Dido: An Automatic Code Generation and Optimization Framework for Stencil Computations on Distributed Memory Architectures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariem%20Saied">Mariem Saied</a>, <a href="https://publications.waset.org/abstracts/search?q=Jens%20Gustedt"> Jens Gustedt</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilles%20Muller"> Gilles Muller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present Dido, a source-to-source auto-generation and optimization framework for multi-dimensional stencil computations. It enables a large programmer community to easily and safely implement stencil codes on distributed-memory parallel architectures with Ordered Read-Write Locks (ORWL) as an execution and communication back-end. ORWL provides inter-task synchronization for data-oriented parallel and distributed computations. It has been proven to guarantee equity, liveness, and efficiency for a wide range of applications, particularly for iterative computations. Dido consists mainly of an implicitly parallel domain-specific language (DSL) implemented as a source-level transformer. It captures domain semantics at a high level of abstraction and generates parallel stencil code that leverages all ORWL features. The generated code is well-structured and lends itself to different possible optimizations. In this paper, we enhance Dido to handle both Jacobi and Gauss-Seidel grid traversals. We integrate temporal blocking to the Dido code generator in order to reduce the communication overhead and minimize data transfers. To increase data locality and improve intra-node data reuse, we coupled the code generation technique with the polyhedral parallelizer Pluto. The accuracy and portability of the generated code are guaranteed thanks to a parametrized solution. The combination of ORWL features, the code generation pattern and the suggested optimizations, make of Dido a powerful code generation framework for stencil computations in general, and for distributed-memory architectures in particular. We present a wide range of experiments over a number of stencil benchmarks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stencil%20computations" title="stencil computations">stencil computations</a>, <a href="https://publications.waset.org/abstracts/search?q=ordered%20read-write%20locks" title=" ordered read-write locks"> ordered read-write locks</a>, <a href="https://publications.waset.org/abstracts/search?q=domain-specific%20language" title=" domain-specific language"> domain-specific language</a>, <a href="https://publications.waset.org/abstracts/search?q=polyhedral%20model" title=" polyhedral model"> polyhedral model</a>, <a href="https://publications.waset.org/abstracts/search?q=experiments" title=" experiments"> experiments</a> </p> <a href="https://publications.waset.org/abstracts/105064/dido-an-automatic-code-generation-and-optimization-framework-for-stencil-computations-on-distributed-memory-architectures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105064.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">3223</span> A Method and System for Secure Authentication Using One Time QR Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Divyans%20Mahansaria">Divyans Mahansaria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> User authentication is an important security measure for protecting confidential data and systems. However, the vulnerability while authenticating into a system has significantly increased. Thus, necessary mechanisms must be deployed during the process of authenticating a user to safeguard him/her from the vulnerable attacks. The proposed solution implements a novel authentication mechanism to counter various forms of security breach attacks including phishing, Trojan horse, replay, key logging, Asterisk logging, shoulder surfing, brute force search and others. QR code (Quick Response Code) is a type of matrix barcode or two-dimensional barcode that can be used for storing URLs, text, images and other information. In the proposed solution, during each new authentication request, a QR code is dynamically generated and presented to the user. A piece of generic information is mapped to plurality of elements and stored within the QR code. The mapping of generic information with plurality of elements, randomizes in each new login, and thus the QR code generated for each new authentication request is for one-time use only. In order to authenticate into the system, the user needs to decode the QR code using any QR code decoding software. The QR code decoding software needs to be installed on handheld mobile devices such as smartphones, personal digital assistant (PDA), etc. On decoding the QR code, the user will be presented a mapping between the generic piece of information and plurality of elements using which the user needs to derive cipher secret information corresponding to his/her actual password. Now, in place of the actual password, the user will use this cipher secret information to authenticate into the system. The authentication terminal will receive the cipher secret information and use a validation engine that will decipher the cipher secret information. If the entered secret information is correct, the user will be provided access to the system. Usability study has been carried out on the proposed solution, and the new authentication mechanism was found to be easy to learn and adapt. Mathematical analysis of the time taken to carry out brute force attack on the proposed solution has been carried out. The result of mathematical analysis showed that the solution is almost completely resistant to brute force attack. Today’s standard methods for authentication are subject to a wide variety of software, hardware, and human attacks. The proposed scheme can be very useful in controlling the various types of authentication related attacks especially in a networked computer environment where the use of username and password for authentication is common. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=authentication" title="authentication">authentication</a>, <a href="https://publications.waset.org/abstracts/search?q=QR%20code" title=" QR code"> QR code</a>, <a href="https://publications.waset.org/abstracts/search?q=cipher%20%2F%20decipher%20text" title=" cipher / decipher text"> cipher / decipher text</a>, <a href="https://publications.waset.org/abstracts/search?q=one%20time%20password" title=" one time password"> one time password</a>, <a href="https://publications.waset.org/abstracts/search?q=secret%20information" title=" secret information "> secret information </a> </p> <a href="https://publications.waset.org/abstracts/71171/a-method-and-system-for-secure-authentication-using-one-time-qr-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71171.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">268</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">3222</span> Climate Impact-Minimizing Road Infrastructure Layout for Growing Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stanislovas%20Buteliauskas">Stanislovas Buteliauskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Au%C5%A1rius%20Juozapavi%C4%8Dius"> Aušrius Juozapavičius</a> </p> <p class="card-text"><strong>Abstract:</strong></p> City road transport contributes significantly to climate change, and the ongoing world urbanization is only increasing the problem. The paper describes a city planning concept minimizing the number of vehicles on the roads while increasing overall mobility. This becomes possible by utilizing a recently invented two-level road junction with a unique property of serving both as an intersection of uninterrupted traffic and an easily accessible transport hub capable of accumulating private vehicles, and therefore becoming an especially effective park-and-ride solution, and a logistics or business center. Optimized layouts of city road infrastructure, living and work areas, and major roads are presented. The layouts are suitable both for the development of new cities as well as for the expansion of existing ones.

The key focus will be on the operation and efficiency of green infrastructure on urban stormwater management. Green infrastructure approach refers to the employment of sufficient green covers as a modern and smart environmental solution to improve the quality of urban environments. Green infrastructure provides a wide variety of micro-scale ecosystem services, such as stormwater runoff management, regulation of extreme air temperatures, reduction of energy consumption, plus a variety of social benefits and human health and wellbeing. However, the cold climate of Finland with seasonal ground frost, snow cover and relatively short growing season bring about questions of whether green infrastructure works as efficiently as expected. To tackle this question, green infrastructure solutions will be studied and analyzed with manifold methods: stakeholder perspectives regarding existing and planned GI solutions will be collected by web based questionnaires, semi structured interviews and group discussions, and analyzed in both qualitative and quantitative methods. Targeted empirical field campaigns will be conducted on selected sites. A systematic literature review with global perspective will support the analyses. The findings will be collected, compiled and analyzed using geographic information systems (GIS). The findings of the research will improve our understanding of the functioning of green infrastructure in the Finnish environment in urban stormwater management, as a landscape element for citizens’ wellbeing, and in climate change mitigation and adaptation. The acquired information will be shared with stakeholders in interactive co-design workshops. As green covers have great demand and potential globally, the conclusions will have relevance in other cool climate regions and may support Finnish business in green infrastructure sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change%20adaptation" title="climate change adaptation">climate change adaptation</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=green%20infrastructure" title=" green infrastructure"> green infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=stormwater" title=" stormwater"> stormwater</a> </p> <a href="https://publications.waset.org/abstracts/86446/sustainable-mitigation-of-urban-stormwater-runoff-the-applicability-of-green-infrastructure-approach-in-finnish-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86446.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">166</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">3220</span> Partial M-Sequence Code Families Applied in Spectral Amplitude Coding Fiber-Optic Code-Division Multiple-Access Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shin-Pin%20Tseng">Shin-Pin Tseng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, numerous spectral amplitude coding (SAC) fiber-optic code-division-multiple-access (FO-CDMA) techniques were appealing due to their capable of providing moderate security and relieving the effects of multiuser interference (MUI). Nonetheless, the performance of the previous network is degraded due to fixed in-phase cross-correlation (IPCC) value. Based on the above problems, a new SAC FO-CDMA network using partial M-sequence (PMS) code is presented in this study. Because the proposed PMS code is originated from M-sequence code, the system using the PMS code could effectively suppress the effects of MUI. In addition, two-code keying (TCK) scheme can applied in the proposed SAC FO-CDMA network and enhance the whole network performance. According to the consideration of system flexibility, simple optical encoders/decoders (codecs) using fiber Bragg gratings (FBGs) were also developed. First, we constructed a diagram of the SAC FO-CDMA network, including (N/2-1) optical transmitters, (N/2-1) optical receivers, and one N×N star coupler for broadcasting transmitted optical signals to arrive at the input port of each optical receiver. Note that the parameter N for the PMS code was the code length. In addition, the proposed SAC network was using superluminescent diodes (SLDs) as light sources, which then can save a lot of system cost compared with the other FO-CDMA methods. For the design of each optical transmitter, it is composed of an SLD, one optical switch, and two optical encoders according to assigned PMS codewords. On the other hand, each optical receivers includes a 1 × 2 splitter, two optical decoders, and one balanced photodiode for mitigating the effect of MUI. In order to simplify the next analysis, the some assumptions were used. First, the unipolarized SLD has flat power spectral density (PSD). Second, the received optical power at the input port of each optical receiver is the same. Third, all photodiodes in the proposed network have the same electrical properties. Fourth, transmitting '1' and '0' has an equal probability. Subsequently, by taking the factors of phase‐induced intensity noise (PIIN) and thermal noise, the corresponding performance was displayed and compared with the performance of the previous SAC FO-CDMA networks. From the numerical result, it shows that the proposed network improved about 25% performance than that using other codes at BER=10-9. This is because the effect of PIIN was effectively mitigated and the received power was enhanced by two times. As a result, the SAC FO-CDMA network using PMS codes has an opportunity to apply in applications of the next-generation optical network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spectral%20amplitude%20coding" title="spectral amplitude coding">spectral amplitude coding</a>, <a href="https://publications.waset.org/abstracts/search?q=SAC" title=" SAC"> SAC</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber-optic%20code-division%20multiple-access" title=" fiber-optic code-division multiple-access"> fiber-optic code-division multiple-access</a>, <a href="https://publications.waset.org/abstracts/search?q=FO-CDMA" title=" FO-CDMA"> FO-CDMA</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20M-sequence" title=" partial M-sequence"> partial M-sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=PMS%20code" title=" PMS code"> PMS code</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20Bragg%20grating" title=" fiber Bragg grating"> fiber Bragg grating</a>, <a href="https://publications.waset.org/abstracts/search?q=FBG" title=" FBG"> FBG</a> </p> <a href="https://publications.waset.org/abstracts/92764/partial-m-sequence-code-families-applied-in-spectral-amplitude-coding-fiber-optic-code-division-multiple-access-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92764.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">384</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">3219</span> A Brief Review of the Axial Capacity of Circular High Strength CFST Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fuat%20Korkut">Fuat Korkut</a>, <a href="https://publications.waset.org/abstracts/search?q=Soner%20Guler"> Soner Guler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concrete filled steel tube (CFST) columns are commonly used in construction applications such as high-rise buildings and bridges owing to its lots of remarkable benefits.

The authors believe that the basis for the process of formation and development of the stock market model infrastructure in Russia is the theory of large systems. This theory considers the financial market infrastructure as a whole on the basis of macroeconomic approach with the further definition of its aims and objectives. Evaluation of the prospects for interaction of securities market institutions will enable identifying the problems associated with the development of this system. The interaction of elements of the stock market infrastructure allows to reduce the costs and time of transactions, thereby freeing up resources of market participants for more efficient operation. Thus, methodology of the transaction analysis allows to determine the financial infrastructure as a set of specialized institutions that form a modern quasi-stable system. The financial infrastructure, based on international standards, should include trading systems, regulatory and supervisory bodies, rating agencies, settlement, clearing and depository organizations. Distribution of financial assets, reducing the magnitude of transaction costs, increased transparency of the market are promising tasks in the solution for questions of services level and quality increase provided by institutions of the securities market financial infrastructure. In order to improve the efficiency of the regulatory system, it is necessary to provide "standards" for all market participants. The development of a clear regulation for the barrier to the stock market entry and exit, provision of conditions for the development and implementation of new laws regulating the activities of participants in the securities market, as well as formulation of proposals aimed at minimizing risks and costs, will enable the achievement of positive results. The latter will be manifested in increasing the level of market participant security and, accordingly, the attractiveness of this market for investors and issuers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=institutional%20infrastructure" title="institutional infrastructure">institutional infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20assets" title=" financial assets"> financial assets</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory%20system" title=" regulatory system"> regulatory system</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20market" title=" stock market"> stock market</a>, <a href="https://publications.waset.org/abstracts/search?q=transparency%20of%20the%20market" title=" transparency of the market"> transparency of the market</a> </p> <a href="https://publications.waset.org/abstracts/102596/building-and-development-of-the-stock-market-institutional-infrastructure-in-russia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102596.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">3217</span> Evaluating of Turkish Earthquake Code (2007) for FRP Wrapped Circular Concrete Cylinders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guler%20S.">Guler S.</a>, <a href="https://publications.waset.org/abstracts/search?q=Guzel%20E."> Guzel E.</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulen%20M."> Gulen M.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fiber Reinforced Polymer (FRP) materials are commonly used in construction sector to enhance the strength and ductility capacities of structural elements.

This simulation code facilitates to select the appropriate parameters for circuit switched networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erlang%20B%20formula" title="Erlang B formula">Erlang B formula</a>, <a href="https://publications.waset.org/abstracts/search?q=call%20blocking" title=" call blocking"> call blocking</a>, <a href="https://publications.waset.org/abstracts/search?q=telephone%20system%20dimension" title=" telephone system dimension"> telephone system dimension</a>, <a href="https://publications.waset.org/abstracts/search?q=Markov%20model" title=" Markov model"> Markov model</a>, <a href="https://publications.waset.org/abstracts/search?q=link%20capacity" title=" link capacity"> link capacity</a> </p> <a href="https://publications.waset.org/abstracts/6283/dimensioning-of-circuit-switched-networks-by-using-simulation-code-based-on-erlang-b-formula" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6283.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">611</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">3215</span> Assessing Renewal Needs of Urban Water Infrastructure Systems: Case Study of Linköping in Sweden</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20Hegazy">Eman Hegazy</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Anderberg"> Stefan Anderberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Joakim%20Krook"> Joakim Krook</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban water infrastructure systems are central to functioning cities. For securing a continuous and efficient supply of the systems services, continuous investment, maintenance, and renewal are needed. Neglecting maintenance and renewal can lead to recurrent breakdown problems as systems age, which makes it more and more difficult to secure efficient long-term supply. Globally, many cities struggle with aging water infrastructure, often due to competing funding priorities. Investment in maintenance and renewal is not prioritized. The problem primarily stems from the challenge of reaping the benefits of investments promptly. The long-term benefits gained from investing in the renewal of water infrastructure may be achievable in the long run, resulting in the oversight of such investments. This leads to a build-up of "renewal debt" for future generations to inherit. Addressing this issue is difficult due to various contributing factors and the complex nature of the systems. The study aims to contribute to an increased understanding of the long-term management challenges of urban water infrastructure, the development of improved maintenance and renewal strategies through the examination of water infrastructure management, and the assessment of the adequacy of the maintenance and renewal in a case study, the city of Linköping, Sweden. Employing a multi-methods approach, this study utilized both qualitative and quantitative methods, including interviews, workshops, and data analysis. The findings of the study provided insights into the current status of the water and sewerage networks in Linkoping, highlighting the risks to ensuring reliable and sustainable water supply and discussing strategies for improving maintenance and renewal. <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=infrastructure%20management" title=" infrastructure management"> infrastructure management</a>, <a href="https://publications.waset.org/abstracts/search?q=renewal%20needs" title=" renewal needs"> renewal needs</a>, <a href="https://publications.waset.org/abstracts/search?q=Sweden" title=" Sweden"> Sweden</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20water%20infrastructure" title=" urban water infrastructure"> urban water infrastructure</a> </p> <a href="https://publications.waset.org/abstracts/171149/assessing-renewal-needs-of-urban-water-infrastructure-systems-case-study-of-linkoping-in-sweden" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171149.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">68</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">3214</span> A Review of the Axial Capacity of Circular High Strength Concrete-Filled Steel Tube Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20G%C3%BClen">Mustafa Gülen</a>, <a href="https://publications.waset.org/abstracts/search?q=Eylem%20G%C3%BCzel"> Eylem Güzel</a>, <a href="https://publications.waset.org/abstracts/search?q=Soner%20Guler"> Soner Guler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concrete filled steel tube (CFST) columns are commonly used in construction applications such as high-rise buildings and bridges owing to its lots of remarkable benefits.

This paper thus studies the effects of different diaphragm in-plane models (including in-plane rigid model and in-plane flexible model) on the seismic performance of structures. Taking an actual industrial plant as an example, the seismic performance of the structure is predicted using different floor diaphragm models, and the analysis errors caused by different diaphragm in-plane models including deformation error and internal force error are calculated. Furthermore, the influence of the aspect ratio on the analysis errors is investigated. Finally, the code rationality is evaluated by assessing the analysis errors of the structure models whose floors were determined as rigid according to the code’s criterion. It is found that different floor models may cause great differences in the distribution of structural internal forces, and the current code may underestimate the influence of the floor in-plane effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20plant" title="industrial plant">industrial plant</a>, <a href="https://publications.waset.org/abstracts/search?q=diaphragm" title=" diaphragm"> diaphragm</a>, <a href="https://publications.waset.org/abstracts/search?q=calculating%20error" title=" calculating error"> calculating error</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20rationality" title=" code rationality"> code rationality</a> </p> <a href="https://publications.waset.org/abstracts/127256/study-on-flexible-diaphragm-in-plane-model-of-irregular-multi-storey-industrial-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127256.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">3211</span> The Food Security and Nutritional Diversity Impacts of Coupling Rural Infrastructure and Value Chain Development: Evidence from a Generalized Propensity Score Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latif%20Apaassongo%20Ibrahim">Latif Apaassongo Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Owusu-Addo%20Ebenezer"> Owusu-Addo Ebenezer</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Bonuedo"> Isaac Bonuedo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structural barriers - including inadequate infrastructure, poor market linkages, and limited access to financial and extension services - have been the major constraints to improved welfare in the semi-arid regions of Ghana; food insecurity and malnutrition are persistent. The effects of infrastructural improvements as countermeasures are often misdirected by confounding effects of other economic, social, and environmental variables. This study applies Directed Acyclic Graphs (DAGs) to map the causal pathways between infrastructure development and household welfare, identifying key mediators and confounders for one such initiative in Ghana. Then, using Generalized Propensity Score (GPS) and Doubly Robust Estimation (IPWRA), this study evaluates the differential roles of government-supported infrastructure improvements in access and intensity of commercial relative to public infrastructure, on household food security and women’s nutritional diversity given three major value-chain improvements. The main findings suggest that these infrastructure improvements positively impact food security and nutrition, with women’s empowerment and nutritional education acting as key mediators. Market access emerged as a stronger causal mechanism relative to productivity gains in linking infrastructure to improved welfare. Membership in Farmer-Based Organizations (FBOs) and participation in agribusiness linkages further amplified these impacts. However, the effects of infrastructure improvements were less clear when combined with the adoption of climate resilience practices, suggesting potential trade-offs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20security" title="food security">food security</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title=" infrastructure"> infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20access" title=" market access"> market access</a>, <a href="https://publications.waset.org/abstracts/search?q=women%27s%20empowerment" title=" women's empowerment"> women's empowerment</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer-based%20organizations" title=" farmer-based organizations"> farmer-based organizations</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20resilience" title=" climate resilience"> climate resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a> </p> <a href="https://publications.waset.org/abstracts/192677/the-food-security-and-nutritional-diversity-impacts-of-coupling-rural-infrastructure-and-value-chain-development-evidence-from-a-generalized-propensity-score-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192677.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">6</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">3210</span> Building Data Infrastructure for Public Use and Informed Decision Making in Developing Countries-Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Busayo%20Fashoto">Busayo Fashoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulhakeem%20Shaibu"> Abdulhakeem Shaibu</a>, <a href="https://publications.waset.org/abstracts/search?q=Justice%20Agbadu"> Justice Agbadu</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Aiyeoribe"> Samuel Aiyeoribe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data has gone from just rows and columns to being an infrastructure itself. The traditional medium of data infrastructure has been managed by individuals in different industries and saved on personal work tools; one of such is the laptop. This hinders data sharing and Sustainable Development Goal (SDG) 9 for infrastructure sustainability across all countries and regions. However, there has been a constant demand for data across different agencies and ministries by investors and decision-makers. The rapid development and adoption of open-source technologies that promote the collection and processing of data in new ways and in ever-increasing volumes are creating new data infrastructure in sectors such as lands and health, among others. This paper examines the process of developing data infrastructure and, by extension, a data portal to provide baseline data for sustainable development and decision making in Nigeria. This paper employs the FAIR principle (Findable, Accessible, Interoperable, and Reusable) of data management using open-source technology tools to develop data portals for public use. eHealth Africa, an organization that uses technology to drive public health interventions in Nigeria, developed a data portal which is a typical data infrastructure that serves as a repository for various datasets on administrative boundaries, points of interest, settlements, social infrastructure, amenities, and others. This portal makes it possible for users to have access to datasets of interest at any point in time at no cost. A skeletal infrastructure of this data portal encompasses the use of open-source technology such as Postgres database, GeoServer, GeoNetwork, and CKan. These tools made the infrastructure sustainable, thus promoting the achievement of SDG 9 (Industries, Innovation, and Infrastructure). As of 6th August 2021, a wider cross-section of 8192 users had been created, 2262 datasets had been downloaded, and 817 maps had been created from the platform. This paper shows the use of rapid development and adoption of technologies that facilitates data collection, processing, and publishing in new ways and in ever-increasing volumes. In addition, the paper is explicit on new data infrastructure in sectors such as health, social amenities, and agriculture. Furthermore, this paper reveals the importance of cross-sectional data infrastructures for planning and decision making, which in turn can form a central data repository for sustainable development across developing countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20portal" title="data portal">data portal</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20infrastructure" title=" data infrastructure"> data infrastructure</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=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/139524/building-data-infrastructure-for-public-use-and-informed-decision-making-in-developing-countries-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139524.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">97</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">3209</span> Enterprise Infrastructure Related to the Product Value Transferred from Intellectual Capital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih%20Chin%20Yang">Chih Chin Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper proposed a new theory of intellectual capital (so called IC) and a value approach in associated with production and market.

The decision to invest in a new infrastructure in transports could take from a few years to some decades. This is mainly because of the need to reserve and spent many capitals, the long payback period, the number of the stakeholders involved in decision process and –many times- the investment and business risks are high. Therefore, the decision assessment framework is an essential challenge linked with the key decision factors meet the stakeholder expectations highlighting project trade-offs, financial risks, business uncertainties and market limitations. This paper examines the decision process for new transport infrastructure projects in cross border regions, where a wide range of stakeholders with different expectation is involved. According to a consequences analysis systemic approach, the relationship of transport infrastructure development, economic system development and stakeholder expectation is analyzed. Adopting the on system of system methodological approach, the decision making framework, variables, inputs and outputs are defined, highlighting the key shareholder’s role and expectations.

Low bill payment and high theft mean utility customers have little incentive to conserve. It also means electricity distribution companies have less to invest in infrastructure maintenance, modernization, and technical upgrades. The low-quality electricity services can result impair the economic benefits from connections to the electrical grid. We study the impacts of two interventions implemented in Karachi, Pakistan, with the goal of reducing distribution losses and increasing revenue recovery: infrastructure improvements that made illegal connections physically more difficult and institutional innovations designed to increase communities’ trust in and cooperation with the utility. Using differences in implementation timing across space, we estimate the interventions’ impacts before the COVID-19 pandemic and their role in mitigating the pandemic’s effects on electricity services. Results indicate that the infrastructure improvements reduced losses, as well as the electricity delivered to the distribution system, a proxy for a generation. The institutional innovations significantly impacted revenue recovery, but not losses in their initial months; however, the efforts mitigated the pandemic’s negative effect on the utility finances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electricity" title="electricity">electricity</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title=" infrastructure"> infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=losses" title=" losses"> losses</a>, <a href="https://publications.waset.org/abstracts/search?q=revenue%20recovery" title=" revenue recovery"> revenue recovery</a> </p> <a href="https://publications.waset.org/abstracts/147407/electricity-services-and-covid-19-understanding-the-role-of-infrastructure-improvements-and-institutional-innovations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147407.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">3206</span> Software Defect Analysis- Eclipse Dataset</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amrane%20Meriem">Amrane Meriem</a>, <a href="https://publications.waset.org/abstracts/search?q=Oukid%20Salyha"> Oukid Salyha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presence of defects or bugs in software can lead to costly setbacks, operational inefficiencies, and compromised user experiences.

In this work, we used a recommendation system to improve the performance of ML models in terms of predicting the code severity and effort estimation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20engineering" title="software engineering">software engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=bugs%20detection" title=" bugs detection"> bugs detection</a>, <a href="https://publications.waset.org/abstracts/search?q=effort%20estimation" title=" effort estimation"> effort estimation</a> </p> <a href="https://publications.waset.org/abstracts/172928/software-defect-analysis-eclipse-dataset" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172928.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">86</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">3205</span> Performance Analysis of MIMO-OFDM Using Convolution Codes with QAM Modulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I%20Gede%20Puja%20Astawa">I Gede Puja Astawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoedy%20Moegiharto"> Yoedy Moegiharto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Zainudin"> Ahmad Zainudin</a>, <a href="https://publications.waset.org/abstracts/search?q=Imam%20Dui%20Agus%20Salim"> Imam Dui Agus Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Annisa%20Anggraeni"> Nur Annisa Anggraeni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Performance of Orthogonal Frequency Division Multiplexing (OFDM) system can be improved by adding channel coding (error correction code) to detect and correct the errors that occur during data transmission. 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">3204</span> Analysing Environmental Licensing of Infrastructure Projects in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ronaldo%20Seroa%20Da%20Motta">Ronaldo Seroa Da Motta</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20Santiago"> Gabriela Santiago</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main contribution of this study is the identification of the factors influencing the environmental licensing process of infrastructure projects in Brazil. These factors will be those that reflect the technical characteristics of the project, the corporate governance of the entrepreneur, and the institutional and regulatory governance of the environmental agency, including the number of interventions by non-licensing agencies. The model conditions these variables to the licensing processing time of 34 infrastructure projects. Our results indicated that the conditions would be more sensitive to the type of enterprise, complexity as in gas pipelines and hydroelectric plants in the most vulnerable biome with a greater value of the enterprise or the entrepreneur's assets, together with the number of employees of the licensing agency. The number of external interventions by other non-licensing institutions does not affect the licensing time. Such results challenge the current criticism that environmental licensing has been often pointed out as a barrier to speed up investments in infrastructure projects in Brazil due to the participation of civil society and other non-licensing institutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20licensing" title="environmental licensing">environmental licensing</a>, <a href="https://publications.waset.org/abstracts/search?q=condionants" title=" condionants"> condionants</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazil" title=" Brazil"> Brazil</a>, <a href="https://publications.waset.org/abstracts/search?q=timing%20process" title=" timing process"> timing process</a> </p> <a href="https://publications.waset.org/abstracts/113916/analysing-environmental-licensing-of-infrastructure-projects-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113916.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">3203</span> Effect of Urban Solid Waste Management Practices on the Sustainability of Urban Infrastructure in Sokoto Metropolis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rilwanu">Rilwanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bello"> Bello</a>, <a href="https://publications.waset.org/abstracts/search?q=Usmn%20Bello%20Saad"> Usmn Bello Saad</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Umar%20Yaro"> Hamza Umar Yaro</a>, <a href="https://publications.waset.org/abstracts/search?q=Isyka%20Ibrahim"> Isyka Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Adebayo%20Oluwole"> Adebayo Oluwole</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimoh%20Abdurrahman"> Jimoh Abdurrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban solid waste management is a critical issue affecting the sustainability of urban infrastructure globally. In rapidly growing cities like Sokoto metropolis inefficient waste management practices led to significant environmental and economic challenges. The research aimed at assessing the effect of waste management practices on the sustainability of urban infrastructure in Sokoto. It also includes assessing the current state of solid waste management practices and its impact on the sustainability of sokoto urban infrastructure. The methodology adopted both primary and secondary sources of data. The targeted population include the staff of SUDA, STEPA and some of the resident in the metropolis. Descriptive method was adopted in the analysis and presentation of data. The study revealed that the waste management practice adopted is solid metropolis was very poor as its associated with poor funding, no availability of sufficient vehicles, bad attitude of resident upon waste disposal which led to blockage of streets and water channels which can subsequently lead to flood. The study recommended that the state government need to increase in funding the relevant authority and also provide the waste dumping sites as well as modern vehicles and equipment to ensure effective solid waste management and disposal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste" title="waste">waste</a>, <a
