In this talk, we present a recursive framework to generate Gray codes for weak orders. We then describe a simple algorithm based on the framework that generates 2-Gray codes for weak orders in constant amortized time per string. This framework can easily be modified to generate other Gray codes for weak orders. We provide an example on using the framework to generate the first Shift Gray code for weak orders, also in constant amortized time, where consecutive strings differ by a shift or a symbol change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=weak%20order" title="weak order">weak order</a>, <a href="https://publications.waset.org/abstracts/search?q=Cayley%20permutation" title=" Cayley permutation"> Cayley permutation</a>, <a href="https://publications.waset.org/abstracts/search?q=Gray%20code" title=" Gray code"> Gray code</a>, <a href="https://publications.waset.org/abstracts/search?q=shift%20Gray%20code" title=" shift Gray code"> shift Gray code</a> </p> <a href="https://publications.waset.org/abstracts/118752/a-simple-recursive-framework-to-generate-gray-codes-for-weak-orders-in-constant-amortized-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118752.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">177</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">1555</span> Skew Cyclic Codes over Fq+uFq+…+uk-1Fq</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Li">Jing Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiuli%20Li"> Xiuli Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies a special class of linear codes, called skew cyclic codes, over the ring <em>R</em>= <em>F<sub>q</sub></em>+<em>uF<sub>q</sub></em>+&hellip;+<em>u<sup>k-</sup></em><sup>1</sup><em>F<sub>q</sub></em>, where <em>q</em> is a prime power.

Through projecting designed light patterns on the object, deformed patterns can be obtained and used for the geometric shape reconstruction. At present, Gray code is the most reliable and commonly used light pattern in the structured light 3D scanner. However, the trade-off between scanning efficiency and accuracy is a long-standing and challenging problem. The design of light patterns plays a significant role in the scanning efficiency and accuracy. Thereby, we proposed a novel encoding method integrating color information and Gray-code to improve the scanning efficiency. We will demonstrate that with the proposed method, the scanning time can be reduced to approximate half of the one needed by Gray-code without reduction of precision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gray-code" title="gray-code">gray-code</a>, <a href="https://publications.waset.org/abstracts/search?q=structured%20light%20scanner" title=" structured light scanner"> structured light scanner</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20shape%20acquisition" title=" 3D shape acquisition"> 3D shape acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20reconstruction" title=" 3D reconstruction"> 3D reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/33773/time-efficient-color-coding-for-structured-light-3d-scanner" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33773.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">457</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">1553</span> Enhancing the Network Security with Gray Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Adi%20Purnomo%20Sidhi">Thomas Adi Purnomo Sidhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, network is an essential need in almost every part of human daily activities.

They limit speakers in a conversation to decide which code they should use to utter particular phrases or words in the course of carrying out their utterance. Every human society is characterized by the existence of diverse linguistic varieties. The speakers of these varieties at some points have various degrees of contact with the non-speakers of their variety, which one of the outcomes of the linguistic contact is code-switching or code-mixing. The work discusses the nature of code-switching and code-mixing in Ogba-English bilinguals’ speeches. It provides a detailed explanation of the concept of code-switching and code-mixing and explains the typology of code-switching and code-mixing and their manifestation in Ogba-English bilingual speakers’ speeches. The findings reveal that code-switching and code-mixing are functionally motivated and being triggered by various conversational contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bilinguals" title="bilinguals">bilinguals</a>, <a href="https://publications.waset.org/abstracts/search?q=code-mixing" title=" code-mixing"> code-mixing</a>, <a href="https://publications.waset.org/abstracts/search?q=code-switching" title=" code-switching"> code-switching</a>, <a href="https://publications.waset.org/abstracts/search?q=Ogba" title=" Ogba"> Ogba</a> </p> <a href="https://publications.waset.org/abstracts/122982/code-switching-and-code-mixing-among-ogba-english-bilingual-conversations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122982.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">181</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">1551</span> Interaction of Non-Gray-Gas Radiation with Opposed Mixed Convection in a Lid-Driven Square Cavity </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Cherifi">Mohammed Cherifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrahmane%20Benbrik"> Abderrahmane Benbrik</a>, <a href="https://publications.waset.org/abstracts/search?q=Siham%20Laouar-Meftah"> Siham Laouar-Meftah</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Lemonnier"> Denis Lemonnier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to numerically investigate the interaction of non-gray-gas radiation with opposed mixed convection in a vertical two-sided lid-driven square cavity. The opposing flows are simultaneously generated by the vertical boundary walls which slide at a constant speed and the natural convection due to the gradient temperature of differentially heated cavity. The horizontal walls are thermally insulated and perfectly reflective. The enclosure is filled with air-H2O-CO2 gas mixture, which is considered as a non-gray, absorbing, emitting and not scattering medium. The governing differential equations are solved by a finite-volume method, by adopting the SIMPLER algorithm for pressure–velocity coupling. The radiative transfer equation (RTE) is solved by the discrete ordinates method (DOM). The spectral line weighted sum of gray gases model (SLW) is used to account for non-gray radiation properties. Three cases of the effects of radiation (transparent, gray and non-gray medium) are studied. Comparison is also made with the parametric studies of the effect of the mixed convection parameter, Ri (0.1, 1, 10), on the fluid flow and heat transfer have been performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=opposed%20mixed%20convection" title="opposed mixed convection">opposed mixed convection</a>, <a href="https://publications.waset.org/abstracts/search?q=non-gray-gas%20radiation" title=" non-gray-gas radiation"> non-gray-gas radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=two-sided%20lid-driven%20cavity" title=" two-sided lid-driven cavity"> two-sided lid-driven cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20ordinate%20method" title=" discrete ordinate method"> discrete ordinate method</a>, <a href="https://publications.waset.org/abstracts/search?q=SLW%20model" title=" SLW model"> SLW model</a> </p> <a href="https://publications.waset.org/abstracts/45398/interaction-of-non-gray-gas-radiation-with-opposed-mixed-convection-in-a-lid-driven-square-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45398.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">319</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">1550</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/abstracts/search?q=Keunhong%20Chae">Keunhong Chae</a>, <a href="https://publications.waset.org/abstracts/search?q=Seokho%20Yoon"> Seokho Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></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.

The street is a basic public product and an important public space in the city, and commerce along the street is an important space for people to consume in the "experience era". Therefore, in this way, it is particularly important to create the vitality of the gray space along the street. From the perspective of vitality construction, this paper takes Sha Zheng Street in Chongqing as the empirical object, combined with the theoretical knowledge of behavioral architecture, and based on the current situation of the commercial gray space along Sha Zheng Street, this paper explores the influence factors and the constraints behind the spatial vitality and then puts forward a general strategy to improve the spatial vitality of the commercial gray space along the street. The author hopes that through the exploration of the vitality of commercial gray space along the street, environmental design can be introduced into the integrated design vision of the urban public environment, and the urban designers can be inspired to create a street environment with a living atmosphere with a small start. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vitality%20creation" title="vitality creation">vitality creation</a>, <a href="https://publications.waset.org/abstracts/search?q=gray%20space" title=" gray space"> gray space</a>, <a href="https://publications.waset.org/abstracts/search?q=street%20commerce" title=" street commerce"> street commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=sha%20zheng%20street" title=" sha zheng street"> sha zheng street</a> </p> <a href="https://publications.waset.org/abstracts/170660/optimization-of-commercial-gray-space-along-the-street-from-the-perspective-of-vitality-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170660.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">100</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">1548</span> Assessing Relationships between Glandularity and Gray Level by Using Breast Phantoms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yun-Xuan%20Tang">Yun-Xuan Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei-Yuan%20Liu"> Pei-Yuan Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun-Mu%20Lu"> Kun-Mu Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Tsung%20Tseng"> Min-Tsung Tseng</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang-Kuang%20Chen"> Liang-Kuang Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuh-Feng%20Tsai"> Yuh-Feng Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Wen%20Lee"> Ching-Wen Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jay%20Wu"> Jay Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast cancer is predominant of malignant tumors in females. The increase in the glandular density increases the risk of breast cancer. BI-RADS is a frequently used density indicator in mammography; however, it significantly overestimates the glandularity. Therefore, it is very important to accurately and quantitatively assess the glandularity by mammography. In this study, 20%, 30% and 50% glandularity phantoms were exposed using a mammography machine at 28, 30 and 31 kVp, and 30, 55, 80 and 105 mAs, respectively. The regions of interest (ROIs) were drawn to assess the gray level. The relationship between the glandularity and gray level under various compression thicknesses, kVp, and mAs was established by the multivariable linear regression. A phantom verification was performed with automatic exposure control (AEC). The regression equation was obtained with an R-square value of 0.928. The average gray levels of the verification phantom were 8708, 8660 and 8434 for 0.952, 0.963 and 0.985 g/cm3, respectively. The percent differences of glandularity to the regression equation were 3.24%, 2.75% and 13.7%. We concluded that the proposed method could be clinically applied in mammography to improve the glandularity estimation and further increase the importance of breast cancer screening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mammography" title="mammography">mammography</a>, <a href="https://publications.waset.org/abstracts/search?q=glandularity" title=" glandularity"> glandularity</a>, <a href="https://publications.waset.org/abstracts/search?q=gray%20value" title=" gray value"> gray value</a>, <a href="https://publications.waset.org/abstracts/search?q=BI-RADS" title=" BI-RADS"> BI-RADS</a> </p> <a href="https://publications.waset.org/abstracts/60797/assessing-relationships-between-glandularity-and-gray-level-by-using-breast-phantoms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60797.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">491</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">1547</span> Conceptualizing Conflict in the Gray Zone: A Comparative Analysis of Diplomatic, Military and Political Lenses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Hardy">John Hardy</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Lushenko"> Paul Lushenko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> he twenty-first century international security order has been fraught with challenges to the credibility and stability of the post-Cold War status quo. Although the American-led international system has rarely been threatened directly by dissatisfied states, an underlying challenge to the international security order has emerged in the form of a slow-burning abnegation of small but significant aspects of the status quo. Meanwhile, those security challenges which have threatened to destabilize order in the international system have not clearly belonged to the traditional notions of diplomacy and armed conflict. Instead, the main antagonists have been both states and non-state actors, the issues have crossed national and international boundaries, and contestation has occurred in a ‘gray zone’ between peace and war. Gray zone conflicts are not easily categorized as military operations, national security policies or political strategies, because they often include elements of diplomacy, military operations, and statecraft in complex combinations. This study applies three approaches to conceptualizing the gray zone in which many contemporary conflicts take place. The first approach frames gray zone conflicts as a form of coercive diplomacy, in which armed force is used to add credibility and commitment to political threats. The second approach frames gray zone conflicts as a form of discrete military operation, in which armed force is used sparingly and is limited to a specific issue. The third approach frames gray zones conflicts as a form of proxy war, in which armed force is used by or through third parties, rather than directly between belligerents. The study finds that each approach to conceptualizing the gray zone accounts for only a narrow range of issues which fall within the gap between traditional notions of peace and war. However, in combination, all three approaches are useful in explicating the gray zone and understanding the character of contemporary security challenges which defy simple categorization. These findings suggest that coercive diplomacy, discrete military operations, and proxy warfare provide three overlapping lenses for conceptualizing the gray zone and for understanding the gray zone conflicts which threaten international security in the early twenty-first century. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gray%20zone" title="gray zone">gray zone</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20security" title=" international security"> international security</a>, <a href="https://publications.waset.org/abstracts/search?q=military%20operations" title=" military operations"> military operations</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20security" title=" national security"> national security</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a> </p> <a href="https://publications.waset.org/abstracts/95592/conceptualizing-conflict-in-the-gray-zone-a-comparative-analysis-of-diplomatic-military-and-political-lenses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95592.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">158</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">1546</span> Characterization of Onboard Reliable Error Correction Code FORSDRAM Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Pitcheswara%20Rao">N.

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 class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=code-switching" title="code-switching">code-switching</a>, <a href="https://publications.waset.org/abstracts/search?q=Facebook" title=" Facebook"> Facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=Facebook%20chatting%20Maldivian%20teenagers" title=" Facebook chatting Maldivian teenagers"> Facebook chatting Maldivian teenagers</a> </p> <a href="https://publications.waset.org/abstracts/71159/code-switching-in-facebook-chatting-among-maldivian-teenagers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71159.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">245</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">1540</span> Development of Fem Code for 2-D Elasticity Problems Using Quadrilateral and Triangular Elements </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Umar%20Kiani">Muhammad Umar Kiani</a>, <a href="https://publications.waset.org/abstracts/search?q=Waseem%20Sakawat"> Waseem Sakawat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents the development of FEM code using Quadrilateral 4-Node (Q4) and Triangular 3-Node (T3) elements.

Quadrilateral element is difficult to handle directly, that is why natural coordinates (eta, ksi) are used. Due to this, Q4 code includes numerical integration (Gauss quadrature). In this case, complete numerical integration is performed using 2 points. On the other hand, T3 element can be modeled directly, by using direct stiffness approach.

The speaker tends to use code switching in his/her speech for better clarification of his/her message to the receiver. It is commonly used in sociocultural countries such as Lebanon because of the various cultures that have come across its lands through history, considering Lebanon is geographically located in the heart of the world, and hence between many cultures and languages. In addition, Lebanon was occupied by Turkish authorities for about 400 years, and later on by the French mandate, where both of these countries forced their languages in official papers and in the Lebanese educational system. In this paper, the importance of code switching in the Lebanese workplace will be examined, stressing the efficiency and amount of the production resulting from code switching in the workplace (factories, universities among other places) in addition to exploring the social, education, religious and cultural factors behind this phenomenon in Lebanon. <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=Lebanon" title=" Lebanon"> Lebanon</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural" title=" cultural"> cultural</a>, <a href="https://publications.waset.org/abstracts/search?q=factors" title=" factors"> factors</a> </p> <a href="https://publications.waset.org/abstracts/143945/code-switching-a-case-study-of-lebanon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143945.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">287</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">1538</span> Features of Testing of the Neuronetwork Converter Biometrics-Code with Correlation Communications between Bits of the Output Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20S.%20Akhmetov">B.

Our approach associates, in the edge node, an optical code-word to a group multicast address. In the core node, a set of tunable decoders are used to send a traffic data to multiple destinations based on the received code-word. The use of code-words, which correspond to the combination of an input port and a set of output ports, allows the implementation of an optical switching matrix.

When working in fields such as software development, having comments in your code that are of good quality is a fundamental requirement. Tackling software problems while making use of programs that have already been built. It is essential for the intention of the source code to be made crystal apparent in the comments that are added to the code. This assists programmers in better comprehending the programs they are working on and enables them to complete software maintenance jobs in a more timely manner. In spite of the fact that comments and documentation are meant to improve readability and maintainability, the vast majority of programmers place the majority of their focus on the actual code that is being written. This study provides a complete and comprehensive overview of the previous research that has been conducted on the topic of code comments. The study focuses on four main topics, including automated comment production, comment consistency, comment classification, and comment quality rating. One is able to get the knowledge that is more complete for use in following inquiries if they conduct an analysis of the proper approaches that were used in this study issue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=code%20commenting" title="code commenting">code commenting</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20code" title=" source code"> source code</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20quality" title=" software quality"> software quality</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20assurance" title=" quality assurance"> quality assurance</a> </p> <a href="https://publications.waset.org/abstracts/166697/analyzing-the-impact-of-code-commenting-on-software-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166697.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1534</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/abstracts/search?q=Cinna%20Soltanpur">Cinna Soltanpur</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ghamari"> Mohammad Ghamari</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Momahed%20Heravi"> Behzad Momahed Heravi</a>, <a href="https://publications.waset.org/abstracts/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/abstracts/search?q=concatenated%20coding" title="concatenated coding">concatenated coding</a>, <a href="https://publications.waset.org/abstracts/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/abstracts/search?q=array%20code" title=" array code"> array code</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20floors" title=" error floors"> error floors</a> </p> <a href="https://publications.waset.org/abstracts/60058/lowering-error-floors-by-concatenation-of-low-density-parity-check-and-array-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60058.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">356</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">1533</span> Exploiting JPEG2000 into Reversible Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Te-Jen%20Chang">Te-Jen Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=I-Hui%20Pan"> I-Hui Pan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuang-Hsiung%20Tan"> Kuang-Hsiung Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shan-Jen%20Cheng"> Shan-Jen Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Wu%20Lan"> Chien-Wu Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Chan%20Hu"> Chih-Chan Hu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the event of multimedia age in order to protect data not to be tampered, damaged, and faked, information hiding technologies are proposed.

Under the undoubted situation, important secret information is transmitted out.Reversible information hiding technologies for high capacity is proposed in this paper. The gray images are as cover media in this technology. We compress gray images and compare with the original image to produce the estimated differences.

However, this information can be compromised in many cases, such as when it is stored locally on the company's computers or when it is transferred between servers and clients. Of these important information leaks, source code leaks are probably the most costly. Because the source code often represents the core technology of the company, especially for the Internet companies, source code leakage may even lead to the company's core products lose market competitiveness, and then lead to the bankruptcy of the company. In recent years, such as Microsoft, AMD and other large companies have occurred source code leakage events, suffered a huge loss. This reveals to us the importance and necessity of preventing source code leakage. This paper aims to find ways to prevent source code leakage based on the direction of operating system, and based on the fact that most companies use Linux or Linux-like system to realize the interconnection between server and client, to discuss how to reduce the possibility of source code leakage during data transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20transmission" title="data transmission">data transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=Linux" title=" Linux"> Linux</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20code" title=" source code"> source code</a>, <a href="https://publications.waset.org/abstracts/search?q=operating%20system" title=" operating system"> operating system</a> </p> <a href="https://publications.waset.org/abstracts/153161/unix-source-code-leak-evaluation-and-feasible-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">270</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1531</span> Code Refactoring Using Slice-Based Cohesion Metrics and AOP</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jagannath%20Singh">Jagannath Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Durga%20Prasad%20Mohapatra"> Durga Prasad Mohapatra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software refactoring is very essential for maintaining the software quality. It is an usual practice that we first design the software and then go for coding. But after coding is completed, if the requirement changes slightly or our expected output is not achieved, then we change the codes. For each small code change, we cannot change the design. In course of time, due to these small changes made to the code, the software design decays. Software refactoring is used to restructure the code in order to improve the design and quality of the software. In this paper, we propose an approach for performing code refactoring. We use slice-based cohesion metrics to identify the target methods which requires refactoring. After identifying the target methods, we use program slicing to divide the target method into two parts. Finally, we have used the concepts of Aspects to adjust the code structure so that the external behaviour of the original module does not change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20refactoring" title="software refactoring">software refactoring</a>, <a href="https://publications.waset.org/abstracts/search?q=program%20slicing" title=" program slicing"> program slicing</a>, <a href="https://publications.waset.org/abstracts/search?q=AOP" title=" AOP"> AOP</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesion%20metrics" title=" cohesion metrics"> cohesion metrics</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20restructure" title=" code restructure"> code restructure</a>, <a href="https://publications.waset.org/abstracts/search?q=AspectJ" title=" AspectJ"> AspectJ</a> </p> <a href="https://publications.waset.org/abstracts/10366/code-refactoring-using-slice-based-cohesion-metrics-and-aop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10366.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">512</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">1530</span> Maximum Distance Separable b-Symbol Repeated-Root γ-Constacylic Codes over a Finite Chain Ring of Length 2</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Laaouine">Jamal Laaouine</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Elhassani%20Charkani"> Mohammed Elhassani Charkani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Let p be a prime and let b be an integer.

The rapid response from the first and second responders in the code blue event will improve patient outcomes and prevent tissue hypoxia that leads to brain injury and other organ failures. Providing 1 minute for the cardiac massage and 2 minutes for defibrillation will significantly improve patient outcomes. As we know, the American Heart Association came out with guidelines for managing cardiac arrest patients. The hospital must provide competent staff to manage this situation. It can be achieved when the staff is well equipped with the skill, attitude, and knowledge to manage this situation with well-planned strategies, i.e., clear guidelines for managing the code blue event, competent staff, and functional equipment. The code blue simulation (CBS) was chosen in the training program for code blue management because it can mimic real scenarios. Having the code blue simulation module will allow the staff to appreciate what they will face during the code blue event, especially since it rarely happens in that area. This CBS module training will help the staff familiarize themselves with the activities that happened during actual events and be able to operate the equipment accordingly. Being challenged and independent in managing the code blue in the early phase gives the patient a better outcome. The CBS module will help the assessor and the hospital management team with the proper tools and guidelines for managing the code blue drill accordingly. As we know, prompt action will benefit the patient and their family. It also indirectly increases the confidence and job satisfaction among the nurses, increasing the standard of care, reducing the complication and hospital burden, and enhancing cost-effective care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=code%20blue%20simulation%20module" title="code blue simulation module">code blue simulation module</a>, <a href="https://publications.waset.org/abstracts/search?q=development%20of%20code%20blue%20simulation%20module" title=" development of code blue simulation module"> development of code blue simulation module</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20blue%20response%20time" title=" code blue response time"> code blue response time</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20blue%20drill" title=" code blue drill"> code blue drill</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiorespiratory%20arrest" title=" cardiorespiratory arrest"> cardiorespiratory arrest</a>, <a href="https://publications.waset.org/abstracts/search?q=managing%20code%20blue" title=" managing code blue"> managing code blue</a> </p> <a href="https://publications.waset.org/abstracts/183021/the-development-validation-and-evaluation-of-the-code-blue-simulation-module-in-improving-the-code-blue-response-time-among-nurses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183021.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">65</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">1527</span> The Gray Dance - An Analysis of Ageism in Dance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paula%20Higa">Paula Higa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper briefly examines age and its impact on a dancer’s performance career. An investigation into the possible reasons why audiences don’t regularly see veteran dancers on stage (termed as the Gray Dancer) supports the research. This analysis reflects some of the social dynamics that shape perceptions of the aging body in the U.S., as well as the correlation between the meaning of old and decay in Western culture. The primary question addressed in this research asks, who has the prerogative to determine when a dancer should stop dancing - society or the dancer themselves The aging process can significantly shorten a performer's professional career. The body has less endurance and is more susceptible to injuries, fatigue, etc. It also becomes less flexible and loses muscular strength and tone. A reduction in physical skills may usher gray dancers to embrace an ideology of shorter careers. However, in today’s age of diversity, equity, and inclusion, the realm of dance performance should reflect the times in which it is rooted; a multi-generational environment where people interact and participate in all of life's events. Overall, this study champions the inclusion of gray dancers as representations of mastery and wisdom akin to those traits associated with age and experience across various professions. Dance is an art form that transcends the assumptions of youthful beauty and physical ability. It serves as a conduit for conveying a lifetime of experiences, emotions, and ideas through the expressive vehicle of the body. Furthermore, it presents audiences with a medium to perceive and comprehend both themselves and life itself, echoing Noverre's insightful contemplation.
