We have used a combination of Entropy term weighting scheme and class based feature (CPBF) vectors as feature selection methods for selecting the best features of Arabic script Web documents for Web page language identifications. Then we input the selected features based on the identification of latent semantics of user profiles using singular value decomposition (SVD). The SVD has been used to remove the noises on the documents retrieved before applying the ICA for topic extraction. We assume that the topic on each document is independent from each other. We have used the information retrieval measures that are precision, recall and F in order to evaluate the effectiveness of the proposed algorithm. From the experiments, we have found that the proposed method could leads to good Arabic script language identification results with good separations of Arabic, Persian, and Urdu languages using the ICA.","PeriodicalId":122964,"journal":{"name":"2008 Second Asia International Conference on Modelling & Simulation (AMS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132200310","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 governing system of fully coupled non-linear partial differential equations describing the process was derived from a mechanistic approach along with the implementation of continuum model. The most extensive formulation of the material used in many hygrothermal and soil transport investigation was adopted as the basis for further development in this work. Two examples comprising one dimensional brick drying and shell drying are solved to validate and demonstrate robustness of the approach. Validation within a one dimensional framework showed that the model presented is in a good agreement with other studies that have been reported previously in the drying of porous material. A two layers case study which illustrate the drying of ceramic shell layers are compared and contrasted against experimental data on shell drying, showing good agreements.","PeriodicalId":122964,"journal":{"name":"2008 Second Asia International Conference on Modelling & Simulation (AMS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122897617","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}

A modified indoor rowing machine and humanoid are modelled using the Visual Nastran dynamic simulation software. The humanoid model is designed based on anthropometric data. The knee and elbow trajectories are obtained for both normal rowing sequence and rowing sequence with voluntary upper body effort. The model developed is evaluated via the torque required at the knee joint and elbow joint throughout the rowing cycle. The model required an adequate amount of torque in order to produce a smooth rowing manoeuvre. The performance of the model developed indicates that the model can be used for future development of FES-assisted indoor rowing exercise.","PeriodicalId":122964,"journal":{"name":"2008 Second Asia International Conference on Modelling & Simulation (AMS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127738696","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}

However, MDA's need to remain reasonably abstract means that it is more a software development approach rather than a standalone methodology, and therefore needs methodology support to be practically useful. Several MDA-based methodologies exist today, yet the need remains for the definition of an instantiable MDA- based development process. We propose a generic lifecycle for MDA-based software development that can be used as a basis for constructing MDA-based methodologies through a Method Engineering (ME) process. The phases and activities of the proposed lifecycle are described herein, with a number of prominent MDA-based methodologies assessed as to their degree of conformance to the proposed lifecycle.","PeriodicalId":122964,"journal":{"name":"2008 Second Asia International Conference on Modelling & Simulation (AMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129210630","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}

This is called the variable-length-packet fixed-length-slot (VPFS) switching scheme. In a VPFS network, all switches adopt the same slot size but slot boundaries are not synchronized from one switch to another. When a packet of any length arrives at a switch, a slot or multiple consecutive slots must be assigned to carry that packet from the input to the destined output, with the condition that the chain of slots carrying the packet cannot be broken up and routed separately in the switch. Given a selected slot size, s, and the average length of packet, x, we show that the expected arrival overhead of a packet due to asynchronous slot boundary is equal to s, thus the maximum throughput of the VPFS scheme is limited to x/(x +s). Although a small slot size is preferable in order to maximize the throughput, the challenge of switching is a compromise. The proposed model can be used for evaluating the performances of different variable-length optical packet switching scenarios.","PeriodicalId":122964,"journal":{"name":"2008 Second Asia International Conference on Modelling & Simulation (AMS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117256396","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 time-varying cell gain (TVCNN) \"hardware annealing\" is also embedded in the network. The test of such a system showed highly efficient in finding globally the optimal solutions for cellular neural networks. The cell gain as an annealing control signal is implemented by using a continuously adjustable MOS amplifier. The adjustable amplifier that used for this function combines an active input and a regulated cascade output. The proposal design method of TVCNN will be implemented by applying both the voltage-mode and current-mode concepts to have an idea of cost and speed in our implementation decision. Experimental simulation shows that the proposed approach is effective for real-time signal and image processing using standard CMOS technology. It offers a high accuracy over an input range. The analytical formulas for determination the values of designable parameters as a transistor sizes and component values are illustrated by an example of optimization task.","PeriodicalId":122964,"journal":{"name":"2008 Second Asia International Conference on Modelling & Simulation (AMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116296047","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}

Super resolution methods are generally classified into reconstruction based and learning based methods. The learning based methods fully learn the intensity prior between all bands of images. For most of these, some fake information can be inevitably introduced into synthesized high resolution image though the image may offer visually good effects. For medical image analysis, it might deteriorate the image analysis and diagnosis performance. In this paper we propose a better learning using real image training set that enhances the high frequency information. The method exploits richness of real-world images. The training set is preprocessed images so as to extract the structural correlation. The technique learns the fine details that correspond to different image structures seen at a low-resolution and then uses those learned relationships to predict fine details in other images.","PeriodicalId":122964,"journal":{"name":"2008 Second Asia International Conference on Modelling & Simulation (AMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114654464","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}

Therefore, there is a growing interest in helping user better find, filter, and manage these resources. Language identification is the first step of understanding text documents which is written in. It is usually a module within multilingual application. In this paper, we introduce language identification of Arabic script documents by letter frequency. Technique used for identification is fuzzy adaptive resonance theory (ART), which is belong to the neural network architectures that perform incremental unsupervised learning. Arabic script documents such as Arabic, Persian and Urdu were used for performing language identification.
