To prepare a suitable site for ZnO nanostructures to grow, the TiO2 seed layer was pre-coated on glass substrate by sol-gel spin-coating. The coated TiO2 thin films were heated at different annealing temperatures; 350, 400, 450, 500 and 550 C for 2 hours in order to determine the best optical quality of the seed layer film for growth of ZnO nanostructures by solution-immersion method. The optical properties of the TiO2: ZnO thin films, as a function of TiO2 annealing temperature have been studied by Photoluminescence (PL) spectroscopy and UV-Vis (Ultraviolet Visible) spectroscopy. Compared to as-grown TiO2 seed layer, red shift was observed on the PL emission peaks of annealed TiO2 seed layer in visible region. This is due to the presence of interstitial oxygen (Oi-). To determine the optical quality and stoichiometric properties of the films, the ratio of the UV emission peak intensity and the visible emission peak intensity, IUV/IVIS were calculated to be 0.32, 0.77, 0.88, 1.50, 1.05 and 0.36 for as-grown, 350, 400, 450, 500 and 550 C, respectively. The higher the intensity of the ratio IUV/IVIS, the better the optical quality of the thin films is. UV-Vis spectra showed that the thin films exhibited high transparency in visible region and high absorption properties in the UV region.","PeriodicalId":240050,"journal":{"name":"2014 2nd International Conference on Electrical, Electronics and System Engineering (ICEESE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125446608","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}

In LS-SVM, the accuracy of the prediction is depends on the selection of kernel parameters. Unfortunately, there is no systematic methodology for selection of their optimal values. Therefore, a novel hybrid Quantum-Inspired Evolutionary Programming - Least Squares Support Vector Machine (QIEP-SVM) is developed for accurate prediction. In QIEP-SVM, Quantum-Inspired Evolutionary Programming (QIEP) is developed to optimise selected parameters for the LS-SVM which are gamma and sigma. QIEP is combining Evolutionary Programming (EP) with quantum mechanics concepts such as interference and superposition in order to enhance classical Evolutionary Programming (EP). The optimal output of DG is first generated using multiobjective Quantum-Inspired Evolutionary Programming (QIEP) at various loading condition according to 24-hours load profile. The data from the simulations are then used as the inputs to the Least-Squares Support Vector Machine (LS-SVM). There are three inputs which are active load (MW), reactive load (MVAR) and minimum voltage (p.u). Whereas, there are five outputs that represents the output of DG at five buses. The objective function for the optimisation process is to minimise the mean square error between predicted and targeted output. The performance of QIEP-SVM is then compared to classical LS-SVM using cross-validation technique and hybrid Artificial Neural Network-Quantum-Inspired Evolutionary Programming (QIEP-ANN). The results of QIEP-SVM model had shown better prediction performance as compared to classical LS-SVM and QIEP-ANN. All simulations in this study were carried out using IEEE 69-bus distribution test system.","PeriodicalId":240050,"journal":{"name":"2014 2nd International Conference on Electrical, Electronics and System Engineering (ICEESE)","volume":"661 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128128376","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}

Hence, this paper is aimed to overcome this problem by using RFID-ARDUINO approach in web-based laboratories attendance system. The propose system will assist the lab instructor to record and manage the student attendance automatically. In addition, the system also provides an evaluation section for lab instructor to key-in and manage the student's experiment marks. The system is divided into two parts, which are the web-based development and system integration with the RFID-ARDUINO technology. An Arduino Uno microcontroller board is use as the hardware platform. Meanwhile, the web design is developed in Adobe Dreamweaver and Adobe Fireworks and deploy in XAMPP application server. Visual Basic scripting is use to integrate between hardware and SQL database. Upon testing, Web-based Laboratory Attendance System (LAS) is successfully facilitated the students' attendance and laboratory management on evaluation of student performance for particular experiment.","PeriodicalId":240050,"journal":{"name":"2014 2nd International Conference on Electrical, Electronics and System Engineering (ICEESE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128352182","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 thickness of the protective layer was determined and applied in the Continuous Wave (CW) and Pulse Echo (PE) ultrasound velocity equations. Corrected Continuous Wave (CCW) was determined as the most accurate fat measurement method and used to measure the intramuscular fat content in chicken fillets. Standard fat measurement method, Soxhlet Method was used to validate the result. The results from the research suggested that it is possible to measure intramuscular fat content non-invasively using ultrasonic velocity measurement. The improvement of the ultrasonic velocity measurement has increased the correlation between fat content measured using Soxhlet Method and ultrasonic velocity compared to the previous research (r= -0.657 vs. r = -0.411). The research presented herewith indicates that with further knowledge of tissue compositions and ultrasound properties, ultrasound technology could be used in the prediction of chicken intramuscular fat percentage with reasonable accuracy.","PeriodicalId":240050,"journal":{"name":"2014 2nd International Conference on Electrical, Electronics and System Engineering (ICEESE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127742222","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}
