In order to make sure the courseware for teaching and learning traditional craft is applicable, effective and support teaching and learning pedagogy, a model for courseware development of teaching and learning traditional craft was developed and derived from methodologies synthesized from related research areas. Through an extensive review of literature, the model was specifically designs to meet the needs of adult learners in a web-based environment with concentrating on designing strategic learning using cognitive apprenticeship approaches. The aim of this study is to verify each component of the proposed model (namely CDTC Model) through initial validation by an Evaluator Committee that was appointed among selected craft instructors from National Craft Institute, Rawang, Malaysia (Institut Kraf Negara (IKN)). The validation is purposely to examine, evaluate, and score the efficacy of each proposed components according to its relevance to the model and was realized through quantitative investigation using questionnaire among Evaluator Committee. The committee, evaluated the model and made recommendations for improving the model. Components validated by committee were used in designing a preliminary version of the model. A significant contribution in this research is to provide relevant preliminary CDTC model for courseware development of teaching and learning traditional craft that will support and preserve our traditional heritage for future generation. With the development of the CDTC model, hopefully it will encourage courseware designers to develop more multimedia applications for teaching and learning traditional craft as well as a good reference for educators, instructional designers, and product developers for developing interactive multimedia applications.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124288364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method is based on pairwise classification by probability from the selective pairwise classifiers. In this research, we focus on the elements of emotion included in a dialogist's voice. Thus, as training datasets for learning the pairwise classifiers, we extract acoustic features from emotionally expressive voice samples spoken by unspecified actors and actresses in films, and TV dramas. The acoustic features adopt duration per single mora, fundamental frequency, energy, and formant. All features except duration per single mora have statistics extracted standard deviation, mean, maximum, minimum, median, timezone of maximum, and timezone of minimum. Pairwise classification classifies a multi-class problem by using a series of binary classifiers. Pairwise classifiers used tree augmented naive bayes, which constructs tree structure among the attributes in naive bayes, by selected subset features. The subset features are selected on every pair of emotions by using naive bayes. This paper reports the accuracy rates of emotion detection by using our method. In experimental results from our voice samples, the emotion classification rates improved.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114053360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When people listen to music, they select songs reflect their own feelings at the time, and then they emotionally evaluate the song. We believe that our emotional evaluation of songs are influenced by the fluctuation properties of both the volume and pitch of songs. Thus, we focused on the fluctuation properties containing dynamic ideas concerning music, and extracted thirty six fluctuation properties concerning both the volume and pitch from each song using the Fast Fourier Transform. We also prepared a subjective evaluation experiment for plural songs using the Semantic Differential method, and obtained an emotional evaluation of the songs. Then, we studied the relationships between the extracted properties and the emotional evaluations of the songs by conducting a multiple discriminant analysis. As a result, a high percentage of the questions were answered correctly and low discriminant errors were shown, and therefore, we suggested that the fluctuation properties of the songs influenced the emotional evaluations of them. Furthermore, we confirmed the especial properties related with the emotional evaluation of the music by taking into consideration the coefficients of the liner discriminants of the canonical variates that describe the discriminant spaces.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115515136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EMRs are used by medical practitioners in storing, handling, and consulting the patients' data. Decision support is one of the most useful and promising features of EMRs, which is yet to be fully adopted in healthcare sector. The reason of the uncommon use of the decision support feature is partly due to the complexity of medical processes and protocols, and partly due to the technological constraint. In this research, the re-admission prediction feature was investigated as a part of decision support in EMRs. The emergency re-admission time window was used to design the proposed re-admission prediction feature. This research also examined how the appropriateness of the width of a time window contributes to the design factor of the proposed re-admission prediction feature. This research demonstrated that the use of emergency re-admission time window is appropriate in the design of re-admission prediction feature. The research outcome allows the users of EMRs to manage the re-admission case in hospital.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115636129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designers often spend considerable time in designing op-amps analytically, and then realize that the simulated circuits do not match with analytical expectations. This is primarily due to modeling of short channel MOS devices using long channel equations. Finally an adhoc mechanism is adopted to realize the op-amp with the help of a simulator. Proposed Potential Distribution Method (PDM) is a method where the design methodology is based on actual behavior of the devices and it is free from any analytical expression. This paper demonstrates the design approach for realizing a fully differential folded cascode op-amp using PDM, which is based on simulator results obtained with predefined bias conditions. The dependency of various performance parameters, like slew rate (SR), unity gain bandwidth (UGB), phase margin (PM), etc. on potentials and current distribution at different nodes is presented. It is found that using these dependencies, the target specifications for an op-amp can be achieved with shorter design time. Also, fine tuning the performance metric can be achieved using PDM. Finally, a fully differential folded cascode op-amp is thus designed and the simulation results are presented.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114646756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aim to make more reliable and robust automatic feature extraction and natural 3D feature construction from 2D features detected on a pair of frontal and profile view face images. We propose several heuristic algorithms to minimize possible errors introduced by prevalent imperfect orthogonal condition and non-coherent luminance trying to address the problems incurred with illumination discrepancies on common surface points in accommodation of multi-views. In our approach, we first extract the 2D features that are visible to both cameras in both views. Then, we estimate the coordinates of the features in the hidden profile view based on the visible features extracted in the two orthogonal views. After that, based on the coordinates of the extracted features, we deform a 3D generic model to perform the desired deformation based modeling. Finally, the face model is texture-mapped by projecting the input 2D images onto the vertices of the face model. As the reconstructed 3D face model is MPEG4 compliant, it can be readily animated by standard MPEG4 facial animation parameters (FAPs). Present study proves the scope of modeling procedure for real-time applications such as face recognition and performance driven facial animation.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126109519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
