It has become even more relevant with the availability of huge amounts of open-source projects. Reuse saves cost, increases the speed of development and improves software reliability. Measuring this reusability is not s straight forward process due to the variety of metrics and qualities linked to software reuse and the lack of comprehensive empirical studies to support the proposed metrics or models. In this paper, a conceptual model is proposed to measure the reusability of OO program code. A comprehensive set of metrics is used to compute the most significant factors of reusability and an empirical investigation is conducted to measure the reusability of the classes of randomly selected open-source Java projects. Additionally, the impact of using inner and anonymous classes on the reusability of their enclosing classes is assessed. The results obtained are thoroughly analyzed to identify the factors behind lack of reusability in open-source OO program code and the impact of nesting on it.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Code%20reuse" title="Code reuse">Code reuse</a>, <a href="https://publications.waset.org/search?q=Low%20Complexity" title=" Low Complexity"> Low Complexity</a>, <a href="https://publications.waset.org/search?q=Empirical%20Analysis" title=" Empirical Analysis"> Empirical Analysis</a>, <a href="https://publications.waset.org/search?q=Modularity" title=" Modularity"> Modularity</a>, <a href="https://publications.waset.org/search?q=Software%20Metrics" title=" Software Metrics"> Software Metrics</a>, <a href="https://publications.waset.org/search?q=Understandability." title=" Understandability."> Understandability.</a> </p> <a href="https://publications.waset.org/9997487/empirical-analysis-of-the-reusability-of-object-oriented-program-code-in-open-source-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9997487/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9997487/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9997487/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9997487/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9997487/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9997487/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9997487/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9997487/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9997487/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9997487/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9997487.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">2181</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">881</span> A Framework to Support Reuse in Object-Oriented Software Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Fathi%20Taibi">Fathi Taibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Reusability is a quality desired attribute in software products. Generally, it could be achieved through adopting development methods that promote it and achieving software qualities that have been linked with high reusability proneness. With the exponential growth in mobile application development, software reuse became an integral part in a substantial number of projects. Similarly, software reuse has become widely practiced in start-up companies. However, this has led to new emerging problems. Firstly, the reused code does not meet the required quality and secondly, the reuse intentions are dubious. This work aims to propose a framework to support reuse in Object-Oriented (OO) software development. The framework comprises a process that uses a proposed reusability assessment metric and a formal foundation to specify the elements of the reused code and the relationships between them. The framework is empirically evaluated using a wide range of open-source projects and mobile applications. The results are analyzed to help understand the reusability proneness of OO software and the possible means to improve it.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Software%20reusability" title="Software reusability">Software reusability</a>, <a href="https://publications.waset.org/search?q=software%20metrics" title=" software metrics"> software metrics</a>, <a href="https://publications.waset.org/search?q=object-oriented%20software" title=" object-oriented software"> object-oriented software</a>, <a href="https://publications.waset.org/search?q=modularity" title=" modularity"> modularity</a>, <a href="https://publications.waset.org/search?q=low%20complexity" title=" low complexity"> low complexity</a>, <a href="https://publications.waset.org/search?q=understandability." title=" understandability."> understandability.</a> </p> <a href="https://publications.waset.org/10012857/a-framework-to-support-reuse-in-object-oriented-software-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10012857/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10012857/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10012857/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10012857/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10012857/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10012857/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10012857/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10012857/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10012857/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10012857/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10012857.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">379</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">880</span> A Rapid Code Acquisition Scheme in OOC-Based CDMA Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Keunhong%20Chae">Keunhong Chae</a>, <a href="https://publications.waset.org/search?q=Seokho%20Yoon"> Seokho Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>We propose a code acquisition scheme called improved multiple-shift (IMS) for optical code division multiple access systems, where the optical orthogonal code is used instead of the pseudo noise code.

We have also developed an important relation between best 1:1 code and the uniquely decipherable code by using different measures of entropy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Codeword" title="Codeword">Codeword</a>, <a href="https://publications.waset.org/search?q=Instantaneous%20code" title=" Instantaneous code"> Instantaneous code</a>, <a href="https://publications.waset.org/search?q=Prefix%20code" title=" Prefix code"> Prefix code</a>, <a href="https://publications.waset.org/search?q=Uniquely%20decipherable%20code" title="Uniquely decipherable code">Uniquely decipherable code</a>, <a href="https://publications.waset.org/search?q=Best%20one-one%20code" title=" Best one-one code"> Best one-one code</a>, <a href="https://publications.waset.org/search?q=Mean%20codewordlength" title=" Mean codewordlength"> Mean codewordlength</a> </p> <a href="https://publications.waset.org/927/codes-and-formulation-of-appropriate-constraints-via-entropy-measures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/927/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/927/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/927/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/927/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/927/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/927/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/927/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/927/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/927/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/927/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/927.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">1298</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">876</span> A Survey of Business Component Identification Methods and Related Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Zhongjie%20Wang">Zhongjie Wang</a>, <a href="https://publications.waset.org/search?q=Xiaofei%20Xu"> Xiaofei Xu</a>, <a href="https://publications.waset.org/search?q=Dechen%20Zhan"> Dechen Zhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With deep development of software reuse, componentrelated technologies have been widely applied in the development of large-scale complex applications. Component identification (CI) is one of the primary research problems in software reuse, by analyzing domain business models to get a set of business components with high reuse value and good reuse performance to support effective reuse. Based on the concept and classification of CI, its technical stack is briefly discussed from four views, i.e., form of input business models, identification goals, identification strategies, and identification process. Then various CI methods presented in literatures are classified into four types, i.e., domain analysis based methods, cohesion-coupling based clustering methods, CRUD matrix based methods, and other methods, with the comparisons between these methods for their advantages and disadvantages. Additionally, some insufficiencies of study on CI are discussed, and the causes are explained subsequently. Finally, it is concluded with some significantly promising tendency about research on this problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Business%20component" title="Business component">Business component</a>, <a href="https://publications.waset.org/search?q=component%20granularity" title=" component granularity"> component granularity</a>, <a href="https://publications.waset.org/search?q=component%20identification" title=" component identification"> component identification</a>, <a href="https://publications.waset.org/search?q=reuse%20performance." title=" reuse performance."> reuse performance.</a> </p> <a href="https://publications.waset.org/5965/a-survey-of-business-component-identification-methods-and-related-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/5965/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/5965/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/5965/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/5965/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/5965/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/5965/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/5965/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/5965/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/5965/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/5965/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/5965.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">1974</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">875</span> An Improved Method on Static Binary Analysis to Enhance the Context-Sensitive CFI</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Qintao%20Shen">Qintao Shen</a>, <a href="https://publications.waset.org/search?q=Lei%20Luo"> Lei Luo</a>, <a href="https://publications.waset.org/search?q=Jun%20Ma"> Jun Ma</a>, <a href="https://publications.waset.org/search?q=Jie%20Yu"> Jie Yu</a>, <a href="https://publications.waset.org/search?q=Qingbo%20Wu"> Qingbo Wu</a>, <a href="https://publications.waset.org/search?q=Yongqi%20Ma"> Yongqi Ma</a>, <a href="https://publications.waset.org/search?q=Zhengji%20Liu"> Zhengji Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Control Flow Integrity (CFI) is one of the most promising technique to defend Code-Reuse Attacks (CRAs). Traditional CFI Systems and recent Context-Sensitive CFI use coarse control flow graphs (CFGs) to analyze whether the control flow hijack occurs, left vast space for attackers at indirect call-sites. Coarse CFGs make it difficult to decide which target to execute at indirect control-flow transfers, and weaken the existing CFI systems actually. It is an unsolved problem to extract CFGs precisely and perfectly from binaries now. In this paper, we present an algorithm to get a more precise CFG from binaries. Parameters are analyzed at indirect call-sites and functions firstly. By comparing counts of parameters prepared before call-sites and consumed by functions, targets of indirect calls are reduced. Then the control flow would be more constrained at indirect call-sites in runtime. Combined with CCFI, we implement our policy. Experimental results on some popular programs show that our approach is efficient. Further analysis show that it can mitigate COOP and other advanced attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Contex-sensitive" title="Contex-sensitive">Contex-sensitive</a>, <a href="https://publications.waset.org/search?q=CFI" title=" CFI"> CFI</a>, <a href="https://publications.waset.org/search?q=binary%20analysis" title=" binary analysis"> binary analysis</a>, <a href="https://publications.waset.org/search?q=code%20reuse%0D%0Aattack." title=" code reuse attack."> code reuse attack.</a> </p> <a href="https://publications.waset.org/10007533/an-improved-method-on-static-binary-analysis-to-enhance-the-context-sensitive-cfi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10007533/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10007533/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10007533/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10007533/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10007533/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10007533/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10007533/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10007533/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10007533/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10007533/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10007533.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">943</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">874</span> Aspect based Reusable Synchronization Schemes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Nathar%20Shah">Nathar Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concurrency and synchronization are becoming big issues as every new PC comes with multi-core processors. A major reason for Object-Oriented Programming originally was to enable easier reuse: encode your algorithm into a class and thoroughly debug it, then you can reuse the class again and again. However, when we get to concurrency and synchronization, this is often not possible. Thread-safety issues means that synchronization constructs need to be entangled into every class involved. We contributed a detailed literature review of issues and challenges in concurrent programming and present a methodology that uses the Aspect- Oriented paradigm to address this problem. Aspects will allow us to extract the synchronization concerns as schemes to be “weaved in" later into the main code. This allows the aspects to be separately tested and verified. Hence, the functional components can be weaved with reusable synchronization schemes that are robust and scalable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Aspect-orientation" title="Aspect-orientation">Aspect-orientation</a>, <a href="https://publications.waset.org/search?q=development%20methodologysoftware%20concurrency" title=" development methodologysoftware concurrency"> development methodologysoftware concurrency</a>, <a href="https://publications.waset.org/search?q=synchronization." title=" synchronization."> synchronization.</a> </p> <a href="https://publications.waset.org/10825/aspect-based-reusable-synchronization-schemes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10825/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10825/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10825/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10825/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10825/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10825/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10825/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10825/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10825/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10825/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10825.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">1246</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">873</span> A Water Reuse System in Wetland Paddy Supports the Growing Industrial Water Needs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Yu-Chuan%20Chang">Yu-Chuan Chang</a>, <a href="https://publications.waset.org/search?q=Chen%20Shi-Kai"> Chen Shi-Kai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A water reuse system in wetland paddy was simulated to supply water for industrial in this paper. A two-tank model was employed to represent the return flow of the wetland paddy.Historical data were performed for parameter estimation and model verification. With parameters estimated from the data, the model was then used to simulate a reasonable return flow rate from the wetland paddy. The simulation results show that the return flow ratio was 11.56% in the first crop season and 35.66% in the second crop season individually; the difference may result from the heavy rainfall in the second crop season. Under the existent pond with surplus active capacity, the water reuse ratio was 17.14%, and the water supplementary ratio was 21.56%. However, the pattern of rainfall, the active capacity of the pond, and the rate of water treatment limit the volume of reuse water. Increasing the irrigation water, dredging the depth of pond before rainy season and enlarging the scale of module are help to develop water reuse system to support for the industrial water use around wetland paddy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Return%20flow" title="Return flow">Return flow</a>, <a href="https://publications.waset.org/search?q=water%20reuse" title=" water reuse"> water reuse</a>, <a href="https://publications.waset.org/search?q=wetland%20paddy" title=" wetland paddy"> wetland paddy</a>, <a href="https://publications.waset.org/search?q=return%20flow%20ratio%20%28RR%29" title=" return flow ratio (RR)"> return flow ratio (RR)</a>, <a href="https://publications.waset.org/search?q=water%20reuse%20ratio%20%28WRR%29" title=" water reuse ratio (WRR)"> water reuse ratio (WRR)</a>, <a href="https://publications.waset.org/search?q=water%20supplementary%20ratio%28WSR%29" title=" water supplementary ratio(WSR)"> water supplementary ratio(WSR)</a> </p> <a href="https://publications.waset.org/9438/a-water-reuse-system-in-wetland-paddy-supports-the-growing-industrial-water-needs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9438/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9438/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9438/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9438/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9438/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9438/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9438/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9438/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9438/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9438/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9438.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">1309</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">872</span> Syntax Sensitive and Language Independent Detection of Code Clones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kazuaki%20Maeda">Kazuaki Maeda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a new technique to detect code clones from the lexical and syntactic point of view, which is based on PALEX source code representation.

RD code is constructed using code level and data level, one of the important properties of this code is that the cross correlation at data level is always zero, which means that Phase intensity Induced Phase (PIIN) is reduced. We find that the performance of the RD code will be better than Modified Frequency Hopping (MFH) and Hadamard code It has been observed through experimental and theoretical simulation that BER for RD code perform significantly better than other codes. Proof –of-principle simulations of encoding with 3 channels, and 10 Gbps data transmission have been successfully demonstrated together with FBG decoding scheme for canceling the code level from SAC-signal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=FBG" title="FBG">FBG</a>, <a href="https://publications.waset.org/search?q=MFH" title=" MFH"> MFH</a>, <a href="https://publications.waset.org/search?q=OCDMA" title=" OCDMA"> OCDMA</a>, <a href="https://publications.waset.org/search?q=PIIN" title=" PIIN"> PIIN</a>, <a href="https://publications.waset.org/search?q=BER." title=" BER."> BER.</a> </p> <a href="https://publications.waset.org/519/performance-of-random-diagonal-codes-for-spectral-amplitude-coding-optical-cdma-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/519/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/519/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/519/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/519/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/519/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/519/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/519/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/519/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/519/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/519/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/519.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">1743</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">870</span> SQL Generator Based On MVC Pattern</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chanchai%20Supaartagorn">Chanchai Supaartagorn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Structured Query Language (SQL) is the standard de facto language to access and manipulate data in a relational database.

The current study aims at evaluating the frequency of code-switching and it investigates between what languages code-switching occurs. Besides the study identifies the types of words that are often codeswitched and the triggers for code switching. The methodology used in this study is mixed method of qualitative and quantitative approach. In this regard, the chat log of a group conversation between 10 teenagers was collected and analyzed. A questionnaire was also administered through online to 24 different teenagers from different corners of the Maldives. The age of teenagers ranged between 16 and 19 years. The findings of the current study revealed that while Maldivian teenagers chat in Facebook they very often code switch and these switches are most commonly between Dhivehi and English, but some other languages are also used to some extent. It also identified the different types of words that are being often code switched among the teenagers. Most importantly it explored different reasons behind code switching among the Maldivian teenagers in Facebook chatting.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Code-switching" title="Code-switching">Code-switching</a>, <a href="https://publications.waset.org/search?q=Facebook" title=" Facebook"> Facebook</a>, <a href="https://publications.waset.org/search?q=Facebook%20chatting%20Maldivian%20teenagers." title=" Facebook chatting Maldivian teenagers."> Facebook chatting Maldivian teenagers.</a> </p> <a href="https://publications.waset.org/10008770/code-switching-in-facebook-chatting-among-maldivian-teenagers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10008770/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10008770/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10008770/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10008770/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10008770/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10008770/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10008770/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10008770/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10008770/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10008770/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10008770.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">1098</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">868</span> Affine Projection Algorithm with Variable Data-Reuse Factor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=ChangWoo%20Lee">ChangWoo Lee</a>, <a href="https://publications.waset.org/search?q=Young%20Kow%20Lee"> Young Kow Lee</a>, <a href="https://publications.waset.org/search?q=Sung%20Jun%20Ban"> Sung Jun Ban</a>, <a href="https://publications.waset.org/search?q=SungHoo%20Choi"> SungHoo Choi</a>, <a href="https://publications.waset.org/search?q=Sang%20Woo%20Kim"> Sang Woo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper suggests a new Affine Projection (AP) algorithm with variable data-reuse factor using the condition number as a decision factor.

Code clone detection tools usually show the results in a textual representation. If the results are large, it makes a problem to software maintainers with understanding them. One of the approaches to overcome the situation is visualization of code clone detection results. A scatter plot is a popular approach to the visualization. However, it represents only one-to-one correspondence and it is difficult to find correspondence of code clones over multiple files. FC graph represents correspondence among files, code clones and packages in Java. All nodes in FC graph are positioned using force-directed graph layout, which is dynami- cally calculated to adjust the distances of nodes until stabilizing them. We applied FC graph to some open source programs and visualized the results. In the author’s experience, FC graph is helpful to grasp correspondence of code clones over multiple files and also code clones with in a file.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=code%20clone%20detection" title="code clone detection">code clone detection</a>, <a href="https://publications.waset.org/search?q=program%20comprehension" title=" program comprehension"> program comprehension</a>, <a href="https://publications.waset.org/search?q=software%20maintenance" title=" software maintenance"> software maintenance</a>, <a href="https://publications.waset.org/search?q=visualization" title=" visualization"> visualization</a> </p> <a href="https://publications.waset.org/4659/visualization-of-code-clone-detection-results-and-the-implementation-with-structured-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/4659/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/4659/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/4659/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/4659/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/4659/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/4659/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/4659/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/4659/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/4659/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/4659/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/4659.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">1513</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">866</span> PIIN Suppression Using Random Diagonal Code for Spectral Amplitude Coding Optical CDMA System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Hilal%20Adnan%20Fadhil"> Hilal Adnan Fadhil</a>, <a href="https://publications.waset.org/search?q=Syed%20Alwei"> Syed Alwei</a>, <a href="https://publications.waset.org/search?q=R.%20Badlishah%20Ahmad"> R. Badlishah Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new code for spectral-amplitude coding optical code-division multiple-access system is proposed called Random diagonal (RD) code. This code is constructed using code segment and data segment. One of the important properties of this code is that the cross correlation at data segment is always zero, which means that Phase Intensity Induced Noise (PIIN) is reduced. For the performance analysis, the effects of phase-induced intensity noise, shot noise, and thermal noise are considered simultaneously. Bit-error rate (BER) performance is compared with Hadamard and Modified Frequency Hopping (MFH) codes. It is shown that the system using this new code matrices not only suppress PIIN, but also allows larger number of active users compare with other codes. Simulation results shown that using point to point transmission with three encoded channels, RD code has better BER performance than other codes, also its found that at 0 dbm PIIN noise are 10-10 and 10-11 for RD and MFH respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=OCDMA" title="OCDMA">OCDMA</a>, <a href="https://publications.waset.org/search?q=MFH" title=" MFH"> MFH</a>, <a href="https://publications.waset.org/search?q=PIIN" title=" PIIN"> PIIN</a>, <a href="https://publications.waset.org/search?q=and%20BER." title=" and BER."> and BER.</a> </p> <a href="https://publications.waset.org/7707/piin-suppression-using-random-diagonal-code-for-spectral-amplitude-coding-optical-cdma-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7707/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7707/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7707/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7707/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7707/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7707/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7707/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7707/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7707/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7707/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7707.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">1787</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">865</span> Valorization of Industrial Wastes on Hybrid Low Embodied Carbon Cement Based Mortars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Z.%20Abdollahnejad">Z.

Some wastes deserve further studies by the scientific community not only because they are generated in high amount but also because they have a low reuse rate. This paper reports results of 32 hybrid cement mortars based on fly ash and waste glass. They allow to explore the influence of mix design on the cost and on the embodied carbon of the hybrid cement mortars. The embodied carbon data for all constituents were taken from the database Ecoinvent.

When it matches a configured code-word, the delayed burst is switched to a set of output ports.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Optical%20multicast" title="Optical multicast">Optical multicast</a>, <a href="https://publications.waset.org/search?q=optical%20burst%20switching%20networks" title=" optical burst switching networks"> optical burst switching networks</a>, <a href="https://publications.waset.org/search?q=optical%20code-words" title=" optical code-words"> optical code-words</a>, <a href="https://publications.waset.org/search?q=tunable%20decoder" title=" tunable decoder"> tunable decoder</a>, <a href="https://publications.waset.org/search?q=virtual%20optical%20memory." title=" virtual optical memory."> virtual optical memory.</a> </p> <a href="https://publications.waset.org/9998597/optical-multicast-over-obs-networks-an-approach-based-on-code-words-and-tunable-decoders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9998597/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9998597/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9998597/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9998597/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9998597/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9998597/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9998597/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9998597/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9998597/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9998597/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9998597.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">1760</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">862</span> Simulation of Hamming Coding and Decoding for Microcontroller Radiation Hardening</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Rehab%20I.%20Abdul%20Rahman">Rehab I.

The complex tasks of retrieving and extracting information from source code documents is vital in the development cycle of the large software systems. The two main subtasks which result from these activities are code duplication prevention and plagiarism detection. In this paper, we propose a Mohamed Amine Ouddan, and Hassane Essafi source code retrieval system based on two-level fingerprint representation, respectively the structural and the semantic information within a source code. A sequence alignment technique is applied on these fingerprints in order to quantify the similarity between source code portions. The specific purpose of the system is to detect plagiarism and duplicated code between programs written in different programming languages belonging to the same class, such as C, Cµ, Java and CSharp. These four languages are supported by the actual version of the system which is designed such that it may be easily adapted for any programming language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Source%20code%20retrieval" title="Source code retrieval">Source code retrieval</a>, <a href="https://publications.waset.org/search?q=plagiarism%20detection" title=" plagiarism detection"> plagiarism detection</a>, <a href="https://publications.waset.org/search?q=clonedetection" title=" clonedetection"> clonedetection</a>, <a href="https://publications.waset.org/search?q=sequence%20alignment." title=" sequence alignment."> sequence alignment.</a> </p> <a href="https://publications.waset.org/12393/a-multilanguage-source-code-retrieval-system-using-structural-semantic-fingerprints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/12393/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/12393/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/12393/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/12393/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/12393/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/12393/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/12393/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/12393/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/12393/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/12393/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/12393.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">1792</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">860</span> The Feasibility of Augmenting an Augmented Reality Image Card on a Quick Response Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Alfred%20Chen">Alfred Chen</a>, <a href="https://publications.waset.org/search?q=Shr%20Yu%20Lu"> Shr Yu Lu</a>, <a href="https://publications.waset.org/search?q=Cong%20Seng%20Hong"> Cong Seng Hong</a>, <a href="https://publications.waset.org/search?q=Yur-June%20Wang"> Yur-June Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research attempts to study the feasibility of augmenting an augmented reality (AR) image card on a Quick Response (QR) code. The authors have developed a new visual tag, which contains a QR code and an augmented AR image card. The new visual tag has features of reading both of the revealed data of the QR code and the instant data from the AR image card. Furthermore, a handheld communicating device is used to read and decode the new visual tag, and then the concealed data of the new visual tag can be revealed and read through its visual display. In general, the QR code is designed to store the corresponding data or, as a key, to access the corresponding data from the server through internet. Those reveled data from the QR code are represented in text. Normally, the AR image card is designed to store the corresponding data in 3-Dimensional or animation/video forms. By using QR code's property of high fault tolerant rate, the new visual tag can access those two different types of data by using a handheld communicating device. The new visual tag has an advantage of carrying much more data than independent QR code or AR image card. The major findings of this research are: 1) the most efficient area for the designed augmented AR card augmenting on the QR code is 9% coverage area out of the total new visual tag-s area, and 2) the best location for the augmented AR image card augmenting on the QR code is located in the bottom-right corner of the new visual tag. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Augmented%20reality" title="Augmented reality">Augmented reality</a>, <a href="https://publications.waset.org/search?q=QR%20code" title=" QR code"> QR code</a>, <a href="https://publications.waset.org/search?q=Visual%20tag" title=" Visual tag"> Visual tag</a>, <a href="https://publications.waset.org/search?q=Handheldcommunicating%20device" title=" Handheldcommunicating device"> Handheldcommunicating device</a> </p> <a href="https://publications.waset.org/5470/the-feasibility-of-augmenting-an-augmented-reality-image-card-on-a-quick-response-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/5470/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/5470/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/5470/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/5470/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/5470/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/5470/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/5470/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/5470/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/5470/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/5470/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/5470.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">1555</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">859</span> Ranking and Unranking Algorithms for k-ary Trees in Gray Code Order</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Fateme%20Ashari-Ghomi">Fateme Ashari-Ghomi</a>, <a href="https://publications.waset.org/search?q=Najme%20Khorasani"> Najme Khorasani</a>, <a href="https://publications.waset.org/search?q=Abbas%20Nowzari-Dalini"> Abbas Nowzari-Dalini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present two new ranking and unranking algorithms for k-ary trees represented by x-sequences in Gray code order.

Several corporate scandals and local (example Transmile and Megan Media) and overseas corporate (example Parmalat and Enron) collapses show that the current corporate governance and regulatory reform are unable to prevent these events from recurring. Arguably, the code of ethics for directors is under research and the current code of ethics only concentrates on binding the work of the employee of the organization as a whole, without specifically putting direct attention to the directors, the group of people responsible for the performance of the company. This study used a semi-structured interview survey of well-known Islamic scholars such as the Mufti to develop the model. It is expected that the outcome of the research is a comprehensive model of code of ethics based on the Islamic principles that can be applied and used by the company to construct a code of ethics for their directors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Code%20of%20ethics" title="Code of ethics">Code of ethics</a>, <a href="https://publications.waset.org/search?q=director" title=" director"> director</a>, <a href="https://publications.waset.org/search?q=Islam" title=" Islam"> Islam</a>, <a href="https://publications.waset.org/search?q=ethics" title=" ethics"> ethics</a> </p> <a href="https://publications.waset.org/14165/directors-islamic-code-of-ethics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14165/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14165/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14165/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14165/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14165/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14165/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14165/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14165/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14165/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14165/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14165.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">1939</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">856</span> Lowering Error Floors by Concatenation of Low-Density Parity-Check and Array Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Cinna%20Soltanpur">Cinna Soltanpur</a>, <a href="https://publications.waset.org/search?q=Mohammad%20Ghamari"> Mohammad Ghamari</a>, <a href="https://publications.waset.org/search?q=Behzad%20Momahed%20Heravi"> Behzad Momahed Heravi</a>, <a href="https://publications.waset.org/search?q=Fatemeh%20Zare"> Fatemeh Zare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Low-density parity-check (LDPC) codes have been shown to deliver capacity approaching performance; however, problematic graphical structures (e.g. trapping sets) in the Tanner graph of some LDPC codes can cause high error floors in bit-error-ratio (BER) performance under conventional sum-product algorithm (SPA). This paper presents a serial concatenation scheme to avoid the trapping sets and to lower the error floors of LDPC code. The outer code in the proposed concatenation is the LDPC, and the inner code is a high rate array code. This approach applies an interactive hybrid process between the BCJR decoding for the array code and the SPA for the LDPC code together with bit-pinning and bit-flipping techniques. Margulis code of size (2640, 1320) has been used for the simulation and it has been shown that the proposed concatenation and decoding scheme can considerably improve the error floor performance with minimal rate loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Concatenated%20coding" title="Concatenated coding">Concatenated coding</a>, <a href="https://publications.waset.org/search?q=low%E2%80%93density%20parity%E2%80%93check%20codes" title=" low–density parity–check codes"> low–density parity–check codes</a>, <a href="https://publications.waset.org/search?q=array%20code" title=" array code"> array code</a>, <a href="https://publications.waset.org/search?q=error%20floors." title=" error floors.

This NZCC code is constructed using address segment and data segment. In this work, the proposed NZCC code is implemented in an optical system using the Opti-System software for the spectral amplitude coded optical code-division multiple-access (SAC-OCDMA) scheme. The main contribution of the proposed NZCC code is the zero cross correlation, which reduces both the MAI and PIIN noises. The proposed NZCC code reveals properties of minimum cross-correlation, flexibility in selecting the code parameters and supports a large number of users, combined with high data rate and longer fiber length. Simulation results reveal that the optical code division multiple access system based on the proposed NZCC code accommodates maximum number of simultaneous users with higher data rate transmission, lower Bit Error Rates (BER) and longer travelling distance without any signal quality degradation, as compared to the former existing SAC-OCDMA codes.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Cross%20Correlation" title="Cross Correlation">Cross Correlation</a>, <a href="https://publications.waset.org/search?q=Optical%20Code%20Division%20Multiple%20Access" title=" Optical Code Division Multiple Access"> Optical Code Division Multiple Access</a>, <a href="https://publications.waset.org/search?q=Spectral%20Amplitude%20Coding%20Optical%20Code%20Division%20Multiple%20Access" title=" Spectral Amplitude Coding Optical Code Division Multiple Access"> Spectral Amplitude Coding Optical Code Division Multiple Access</a>, <a href="https://publications.waset.org/search?q=Multiple%20Access%20Interference" title=" Multiple Access Interference"> Multiple Access Interference</a>, <a href="https://publications.waset.org/search?q=Phase%20Induced%20Intensity%20Noise" title=" Phase Induced Intensity Noise"> Phase Induced Intensity Noise</a>, <a href="https://publications.waset.org/search?q=New%20Zero%20Cross%20Correlation%20code." title=" New Zero Cross Correlation code."> New Zero Cross Correlation code.</a> </p> <a href="https://publications.waset.org/10003968/design-and-performance-analysis-of-one-dimensional-zero-cross-correlation-coding-technique-for-a-fixed-wavelength-hopping-sac-ocdma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10003968/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10003968/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10003968/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10003968/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10003968/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10003968/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10003968/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10003968/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10003968/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10003968/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10003968.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">2243</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">853</span> Implementation of a Reed-Solomon Code as an ECC in Yet Another Flash File System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Sungjoon%20Sim">Sungjoon Sim</a>, <a href="https://publications.waset.org/search?q=Soongyu%20Kwon"> Soongyu Kwon</a>, <a href="https://publications.waset.org/search?q=Dongjae%20Song"> Dongjae Song</a>, <a href="https://publications.waset.org/search?q=Jong%20Tae%20Kim"> Jong Tae Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flash memory has become an important storage device in many embedded systems because of its high performance, low power consumption and shock resistance. Multi-level cell (MLC) is developed as an effective solution for reducing the cost and increasing the storage density in recent years. However, most of flash file system cannot handle the error correction sufficiently. To correct more errors for MLC, we implement Reed-Solomon (RS) code to YAFFS, what is widely used for flash-based file system. RS code has longer computing time but the correcting ability is much higher than that of Hamming code. <p class="card-text"><strong>Keywords:</strong> <a
