The PALEX code contains the recorded parsing actions and also lexical formatting information including white spaces and comments. We can record a list of parsing actions (shift, reduce, and reading a token) during a compiling process after a compiler finishes analyzing the source code. The proposed technique has advantages for syntax sensitive approach and language independency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Code%20Clones" title="Code Clones">Code Clones</a>, <a href="https://publications.waset.org/search?q=Source%20Code%20Representation" title=" Source Code Representation"> Source Code Representation</a>, <a href="https://publications.waset.org/search?q=XML" title=" XML"> XML</a>, <a href="https://publications.waset.org/search?q=Parser" title="Parser">Parser</a>, <a href="https://publications.waset.org/search?q=Parser%20Generator" title=" Parser Generator"> Parser Generator</a> </p> <a href="https://publications.waset.org/13000/syntax-sensitive-and-language-independent-detection-of-code-clones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13000/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13000/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13000/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13000/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13000/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13000/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13000/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13000/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13000/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13000/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13000.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">1460</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">740</span> Visualization of Code Clone Detection Results and the Implementation with Structured Data</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> <p>This paper describes a code clone visualization method, called FC graph, and the implementation issues. 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&rsquo;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">739</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.

High rumen degradation rate of faba bean protein may lead to inconstant rumen conditions that could have a prominent impact on rumen microbial diversity. Amplified Ribosomal DNA Restriction Analysis (ARDRA) is utilized to monitor diversity of rumen microbes on sheep fed low quality forage supplemented by faba beans. Four mature merino sheep with existing rumen cannula were used in this study according to 4 x 4 Latin square design. The results of study indicated that there were 37 different ARDRA types identified out of 136 clones examined. Among those clones, five main clone types existed across the treatments with different percentages. In conclusion, the ARDRA method is potential to be used as a routine tool to assess the temporary changes in the rumen community as a result of different feeding strategies.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=ARDRA%20method" title="ARDRA method">ARDRA method</a>, <a href="https://publications.waset.org/search?q=clones" title=" clones"> clones</a>, <a href="https://publications.waset.org/search?q=microbial%20diversity" title=" microbial diversity"> microbial diversity</a>, <a href="https://publications.waset.org/search?q=ribotypes" title=" ribotypes"> ribotypes</a>, <a href="https://publications.waset.org/search?q=ruminants." title=" ruminants."> ruminants.</a> </p> <a href="https://publications.waset.org/10006201/amplified-ribosomal-dna-restriction-analysis-method-to-assess-rumen-microbial-diversity-of-ruminant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10006201/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10006201/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10006201/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10006201/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10006201/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10006201/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10006201/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10006201/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10006201/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10006201/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10006201.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">1466</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">736</span> Performance of Random Diagonal Codes for Spectral Amplitude Coding Optical CDMA Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Hilal%20A.%20Fadhil">Hilal A.

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">735</span> Code-Switching in Facebook Chatting Among Maldivian Teenagers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Aaidha%20Hammad">Aaidha Hammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This study examines the phenomenon of code switching among teenagers in the Maldives while they carry out conversations through Facebook in the form of &ldquo;Facebook Chatting&rdquo;. 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">734</span> Flowering Response of a Red Pitaya Germplasm Collection to Lighting Addition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Dinh-Ha%20Tran">Dinh-Ha Tran</a>, <a href="https://publications.waset.org/search?q=Chung-Ruey%20Yen"> Chung-Ruey Yen</a>, <a href="https://publications.waset.org/search?q=Yu-Kuang%20H.%20Chen"> Yu-Kuang H.

The night-breaking treatment was conducted during the period of 10 Oct. 2013 to 5 Mar. 2014 with 4-continuous hours (22.00 &ndash; 02.00 hrs) of additional lighting daily using incandescent bulbs (100W). Among cultivars and clones tested, twenty-three genotypes, most belonging to the red-magenta flesh type, were found to have positively flowering response to the lighting treatment. The duration of night-breaking treatment for successful flowering initiation varied from 33- 48 days. The lighting-sensitive genotypes bore 1-2 flowering flushes. Floral and fruiting stages took 21-26 and 46-59 days, respectively. Among sixteen fruiting genotypes, the highest fruit set rates were found in Damao 9, D4, D13, Chaozou large, Chaozhou 5, Small Nick and F22. Five cultivars and clones (Orejona, D4, Chaozhou large, Chaozhou 5 and Small Nick) produced fruits with an average weight of more than 300 g per fruit which were higher than those of the fruits formed in the summer of 2013. Fruits produced during off-season containing total soluble solids (TSS) from 17.5 to 20.7oBrix, which were higher than those produced inseason.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Flowering%20response" title="Flowering response">Flowering response</a>, <a href="https://publications.waset.org/search?q=long-day%20plant" title=" long-day plant"> long-day plant</a>, <a href="https://publications.waset.org/search?q=night-breaking%0D%0Atreatment" title=" night-breaking treatment"> night-breaking treatment</a>, <a href="https://publications.waset.org/search?q=off-season%20production" title=" off-season production"> off-season production</a>, <a href="https://publications.waset.org/search?q=pitaya." title=" pitaya."> pitaya.</a> </p> <a href="https://publications.waset.org/10000565/flowering-response-of-a-red-pitaya-germplasm-collection-to-lighting-addition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10000565/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10000565/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10000565/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10000565/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10000565/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10000565/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10000565/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10000565/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10000565/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10000565/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10000565.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">3963</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">733</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.

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">732</span> Optical Multicast over OBS Networks: An Approach Based On Code-Words and Tunable Decoders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Maha%20Sliti">Maha Sliti</a>, <a href="https://publications.waset.org/search?q=Walid%20Abdallah"> Walid Abdallah</a>, <a href="https://publications.waset.org/search?q=Noureddine%20Boudriga"> Noureddine Boudriga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In the frame of this work, we present an optical multicasting approach based on optical code-words.

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">728</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">727</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.

Source code obfuscation aims in obscuring the source code to hide the functionality of the codes. This paper proposes an Array data transformation in order to obfuscate the source code which uses arrays. The applications using the proposed data structures force the programmer to obscure the logic manually. It makes the developed obscured codes hard to reverse engineer and also protects the functionality of the codes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Reverse%20Engineering" title="Reverse Engineering">Reverse Engineering</a>, <a href="https://publications.waset.org/search?q=Source%20Code%20Obfuscation." title=" Source Code Obfuscation."> Source Code Obfuscation.</a> </p> <a href="https://publications.waset.org/2537/array-data-transformation-for-source-code-obfuscation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/2537/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/2537/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/2537/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/2537/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/2537/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/2537/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/2537/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/2537/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/2537/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/2537/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/2537.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">2036</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">725</span> Directors- Islamic Code of Ethics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ahmad%20Saiful%20Azlin%20Puteh%20Salin">Ahmad Saiful Azlin Puteh Salin</a>, <a href="https://publications.waset.org/search?q=Norlela%20Kamaludin"> Norlela Kamaludin</a>, <a href="https://publications.waset.org/search?q=Siti%20Khadijah%20Ab%20Manan"> Siti Khadijah Ab Manan</a>, <a href="https://publications.waset.org/search?q=Mohd%20Shatari%20Abdul%20Ghafar"> Mohd Shatari Abdul Ghafar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses a new model of Islamic code of ethics for directors. 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">724</span> Morphological Characteristics and Pollination Requirement in Red Pitaya (Hylocereus spp.) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Dinh%20Ha">Dinh Ha</a>, <a href="https://publications.waset.org/search?q=Tran"> Tran</a>, <a href="https://publications.waset.org/search?q=Chung%20-%20Ruey%20Yen"> Chung - Ruey Yen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This study explored the morphological characteristics and effects of pollination methods on fruit set and characteristics in 4 red pitaya (<em>Hylocereus </em>spp.) clones.

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.

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.

In our previous paper, we used Genetic algorithm (GA), to recover spreading code. Although genetic algorithms (GAs) are well known for their robustness in solving complex optimization problems, but nonetheless, by increasing the length of the code, we will often lead to an unacceptable slow convergence speed. To solve this problem we introduce Particle Swarm Optimization (PSO) into code estimation in spread spectrum communication system. In searching process for code estimation, the PSO algorithm has the merits of rapid convergence to the global optimum, without being trapped in local suboptimum, and good robustness to noise. In this paper we describe how to implement PSO as a component of a searching algorithm in code estimation. Swarm intelligence boasts a number of advantages due to the use of mobile agents. Some of them are: Scalability, Fault tolerance, Adaptation, Speed, Modularity, Autonomy, and Parallelism. These properties make swarm intelligence very attractive for spread spectrum code estimation. They also make swarm intelligence suitable for a variety of other kinds of channels. Our results compare between swarm-based algorithms and Genetic algorithms, and also show PSO algorithm performance in code estimation process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Code%20estimation" title="Code estimation">Code estimation</a>, <a href="https://publications.waset.org/search?q=Particle%20Swarm%20Optimization%28PSO%29" title=" Particle Swarm Optimization(PSO)"> Particle Swarm Optimization(PSO)</a>, <a href="https://publications.waset.org/search?q=Spread%20spectrum." title=" Spread spectrum."> Spread spectrum.</a> </p> <a href="https://publications.waset.org/12337/spread-spectrum-code-estimationby-particle-swarm-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/12337/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/12337/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/12337/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/12337/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/12337/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/12337/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/12337/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/12337/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/12337/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/12337/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/12337.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">2136</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">717</span> Semi-Blind Two-Dimensional Code Acquisition in CDMA Communications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Rui%20Wu">Rui Wu</a>, <a href="https://publications.waset.org/search?q=Tapani%20Ristaniemi"> Tapani Ristaniemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we propose a new algorithm for joint time-delay and direction-of-arrival (DOA) estimation, here called two-dimensional code acquisition, in an asynchronous directsequence code-division multiple-access (DS-CDMA) array system.

The speed of error detection and correction of a code is largely dependent upon the associated encoder and decoder circuits. The complexity and the speed of such circuits are determined by the number of 1?s in the parity check matrix (PCM). The number of 1?s in the parity check matrix for the code proposed by the authors are fewer than in any currently known single error correcting/double error detecting code. This results in simplified encoding and decoding circuitry for error detection and correction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Decoder" title="Decoder">Decoder</a>, <a href="https://publications.waset.org/search?q=Hsiao%20code" title=" Hsiao code"> Hsiao code</a>, <a href="https://publications.waset.org/search?q=Parity%20Check%20Matrix" title=" Parity Check Matrix"> Parity Check Matrix</a>, <a href="https://publications.waset.org/search?q=Syndrome%20Pattern." title=" Syndrome Pattern."> Syndrome Pattern.</a> </p> <a href="https://publications.waset.org/926/decoder-design-for-a-new-single-error-correctingdouble-error-detecting-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/926/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/926/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/926/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/926/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/926/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/926/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/926/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/926/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/926/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/926/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/926.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">2080</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">714</span> Variable Rate Superorthogonal Turbo Code with the OVSF Code Tree</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Insah%20Bhurtah">Insah Bhurtah</a>, <a href="https://publications.waset.org/search?q=P.%20Clarel%20Catherine"> P.

In this work, Orthogonal Variable Spreading Factor (OVSF) codes are used with the same principles applied in a low-rate superorthogonal turbo code due to their variable-length properties. The introduced system is the Variable Rate Superorthogonal Turbo Code (VRSTC) where puncturing is not performed on the encoder&rsquo;s final output but rather before selecting the output to achieve higher rates. Due to bandwidth expansion, the codes outperform an ordinary turbo code in the AWGN channel. Simulations results show decreased performance compared to those obtained with the employment of Walsh-Hadamard codes. However, with OVSF codes, the VRSTC system keeps the orthogonality of codewords whilst producing variable rate codes contrary to Walsh-Hadamard codes where puncturing is usually performed on the final output.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=CDMA" title="CDMA">CDMA</a>, <a href="https://publications.waset.org/search?q=MAP%20Decoding" title=" MAP Decoding"> MAP Decoding</a>, <a href="https://publications.waset.org/search?q=OVSF" title=" OVSF"> OVSF</a>, <a href="https://publications.waset.org/search?q=Superorthogonal%20Turbo%20Code." title=" Superorthogonal Turbo Code.

First, it examined whether the code-mixing rate was different in Mandarin Chinese and English contexts. Second, it explored the syntactic categories of code-mixing in Singapore bilingual children. Moreover, this study investigated whether morphological information was preserved when inserting syntactic components into the matrix language. Data are derived from the Singapore Bilingual Corpus, in which the recordings and transcriptions of sixty English-Mandarin 5-to-6-year-old children were preserved for analysis. Results indicated that the rate of code-mixing was asymmetrical in the two language contexts, with the rate being significantly higher in the Mandarin context than that in the English context. The asymmetry is related to language dominance in that children are more likely to code-mix when using their nondominant language. Concerning the syntactic categories of code-mixing words in the Singaporean bilingual children, we found that noun-mixing, verb-mixing, and adjective-mixing are the three most frequently used categories in code-mixing in the Mandarin context. This pattern mirrors the syntactic categories of code-mixing in the Cantonese context in Cantonese-English bilingual children, and the general trend observed in lexical borrowing. Third, our results also indicated that English vocabularies that carry morphological information are embedded in bare forms in the Mandarin context. These findings shed light upon how bilingual children take advantage of the two languages in mixed utterances in a bilingual environment.</p> <p class="card-text"><strong>Keywords:</strong> <a
