FEA is a powerful tool to study the reproduction of a particular loading on anatomical structures with various parameters. Many studies used FEA as a solution for failure prediction with variable of unknown stresses. The effects of external impact conditions are demonstrated by stress analysis. The raw images collected from CT scan were rendered into 3D model. The surface model was repaired by Autodesk 3ds Max and converted into editable surface model for the ease of solid bodies conversion. The surface model was further converted into solid model by using Autodesk Inventor. The meshing technique used is tetrahedral shape function which consists of solid 10 nodes and 92 elements. The element size is set at finer value of less than 0.005 mm. The comparison of both CT scans generated 3D model and computed-based 3D model are to be done in the future study.","PeriodicalId":282263,"journal":{"name":"2012 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124374358","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}

With building automation and remote control, appliances can be switched on or off without physically switching them on by their switches. Hence, an embedded web server is developed to achieve remote control of switches and autonomous control with predefined rules. A web server is used instead of conventional approach where the controls of switches are performed through the web browser via local area network or the internet. The embedded server is developed from a Microchip PIC24FJ256GB106 16-bit microcontroller together with an Ethernet controller ENC28J60 using TCP/IP stack provided by Microchip and utilizes USB flash drive as storage medium. This paper discusses the testing of components that make up the system, together with problems encountered and methods to solve the problems. Performance of the embedded webserver is obtained and documented. Optimizations were performed to increase the system's performance. The system is designed to use JavaScript to emulate HTTP digest authentication by using a one way hash function to encode the salted username and password for user authentication purpose. Power control modules were designed and developed to control AC power devices. AC light bulbs were used to demonstrate the capability of the system to operate in AC environment.","PeriodicalId":282263,"journal":{"name":"2012 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129110007","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 growth of voice-controlled technologies has becoming part of our daily life, nevertheless variability in speech makes these spoken language technologies relatively difficult. One of the profound variability is accent. By classifying accent types, different models could be developed to handle SI-ASR. In this paper, we classified three accents in English language recorded from three main ethnicities in Malaysia namely Malay, Chinese and Indian using artificial neural network model. All experiments were performed in speaker-independent and three most accent-sensitive words-independent modes. Mel-bands spectral energy was extracted from eighteen bands taking the statistical values of each speech sample i.e. mean, standard deviation, kurtosis and the ratio of standard deviation to kurtosis to characterize the spectral energy distribution. The system was evaluated using independent test dataset, partial-independent test dataset and training dataset. The best three-class accuracy rate of 99.01% with independent test dataset was obtained. The overall accuracy rate for several trials was averaged to 96.79% with the average learning time at 49 epochs.","PeriodicalId":282263,"journal":{"name":"2012 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128397815","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}

Using water flow rate 0.400 kg/s and inlet temperature 30°C, the temperature distribution is simulated and the temperature values are used as a means to predict each CPV cell's operating temperature. It is observed that a solar cell located at the central region of the array experiences the highest temperature of 58.3°C, while CPV cells located furthest to the center are operating at 7°C lower than the center region cell. For comparison purpose, we also investigated the effect of uniform temperature distribution for all the cells at 55.2°C. It is found that the output power varies by less than 1W compared to the case of non-uniform temperature distribution where each solar cell is experiencing a different temperature value. On the other hand, the output power increases to 462.70 W when the array temperature is reduced to 40°C, while the output power dropped to 418.60 W when the array temperature is increased to 100°C. Through better understanding of temperature effects to dense array CPV performance, a suitable cooling system can be designed to minimize power loss.","PeriodicalId":282263,"journal":{"name":"2012 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115575131","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}

Supplementary damping stabilizer can be added to the internal AC or DC voltage control channel of the STATCOM inputs to implement the task of power oscillation damping controller (POD). This study presents the simultaneously coordinated design of the multiple damping controllers between PSS and STATCOM-based POD or between different multiple STATCOM-based POD controllers without conventional PSS in a single-machine infinite-bus power system. The coordinated design is formulated as an optimization problem, which is solved by a particle swarm optimization (PSO) algorithm to search for optimum stabilizer's parameter settings that optimize a given eigenvalue based objective function. The simulation results reveals that the coordinated designing of the multiple damping controllers provide satisfactory performance in terms of an increasing the damping rate and decrease the settling time in comparison to the individual damping controllers.","PeriodicalId":282263,"journal":{"name":"2012 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124129851","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}
