Title:	APPLICATION USING AUGMENTED REALITY
Author:	MAURICIO PLAZA TORRES
Source:	Journal of Theoretical and Applied Information Technology Vol 21. No. 1 -- 2010
Abstract	Laparoscopy technique has caused a high impact in the surgical community. The success of this technology is the application of the surgical conventional practices to access in the abdominal cavity, with diagnostic and therapeutic purposes, with a minimum surgical intervention. This procedure has been used for biliary lithiasis, now it is an advanced procedure in several pathologies interventions; the reason is because surgical set of instruments has been improving. The base of laparoscopy procedure is the video surgery, which for nature needs the training of the surgeon and the knowledge of the set of instruments, as well as his advantages and his limitations. The correct use of this technology prevents surgical problems and the correct knowledge of the instruments in every particular condition, avoids human operation mistakes. Additionally to all inherent problems in the use of the technology, an additional variable exists; the position of the image is displayed in a monitor, in a different position from the area of operation. This implies an additional training of the surgeon so that the surgical act has fluency and continuity. The image is taken by an endocamera and projected in a monitor. The first barrier that the surgeon must overcome is the difference between the position of the image and the place of navigation of the instruments. If there is the possibility of projecting the image on the human body with the same characteristics of an open surgery, we can have closer this methodology over to the traditional surgeries, achieving the advantages of the video surgery over a virtual traditional surgery. With this new technological modification, the surgeon does not use the image of monitor and in his place he sees, in his visual field, the internal image of the abdomen like an open traditional surgery. The training would centre on the use of the laparoscopy instruments and the surgeon will feel the sensation of being in a traditional operation, with consistent progress in his surgical skill. In order to obtain this objective, we can propose the use of the augmented reality technique, which allows having the human real body in the field of vision and the superposition of the internal image of the abdomen [4].

Title:	E-VEHICLE: AN IMPLICATION TO NEXT GENERATION TRANSPORTATION

Abstract	Casualties due to traffic accidents are increasing day by day. Think of this message being displayed on your computer screen while you were driving “there’s a possibility of collision with a car in the next few minutes if you go on driving with this speed and direction”. Our research is intended towards developing collision avoidance architecture for the latest Intelligent Transport System. The exchange of safety messages among vehicles and with infrastructure devices poses major challenges. Specially, safety messages have to be adaptively distributed within a certain range of a basically unbounded system. These messages are to be well coordinated and processed via different algorithms between two different cars which is embedded radar or without radar. With this motivation the author sets the objectives like achieving a data rate of 100 Mbps for full vehicular mobility, sensing of nearby vehicles using digital radar, integrating both communication and radar to have one wireless embedded system for providing concurrent vehicular communication and safety. To achieve 100 Mbps data rate, different communication technologies at the transmitter as well as at the receiver sections are tried and compared according to CALM (Continuous Air interface for Long and Medium distance ) standard framed by ITU. Finally, MIMO (Multiple-Input Multiple-Output) based noble signal scheme “Hybrid BLAST STBC” at the transmitter and ML (Maximum Likehood) detector approach has evolved fulfilling the objective. This scheme combines MIMO and STBC (Space Time Block Code) to generate a system functionally superior to MIMO and STBC systems. For radar based sensing, MIMO radar is found to be more effective on road condition. Finally, authors would like to provide an implication of realistic E-vehicle for next generation transportation system. The above performances of our proposed system are compared with the conventional scheme by software simulations which validate the analytical results.

Abstract	In estimate, around six billion fluorescent lamps are discarded every year. In human life, suddenly fused fluorescent lamp creates a lot of problem. Then authors think how fused fluorescent lamp can be re-utilized and this mentioned problem can be overcome. Therefore authors motivated a simple method to design a prototype model in the laboratory. This paper presents a new concept to analyze the process of lighting with fused fluorescent lamp using bridge rectifier circuit. And what are the role of choke & starter in this mechanism of circuit model. Experimentally, characteristics of fused fluorescent lamp are also analyzed throughout this paper

Title:	OPTIMAL POINT TARGET DETECTION USING DIGITAL RADARS
Author:	NIRMALENDU BIKAS SINHA, M.MITRA
Source:	Journal of Theoretical and Applied Information Technology Vol 21. No. 1 -- 2010
Abstract	This paper presents an overview of recent progress of radar for the image detection and characterization of targets. MIMO radar can improve on conventional target detection, parameter identification, and target classification performance via diversity of, among other things, its simultaneously transmitted waveforms. However, the mutual interference among the waveforms may lead to considerable performance degradation in suppressing clutter near targets. The performance of the conventional radar for moving target detection have been evaluated analytically mainly focusing on the Swerling model II, IV and V and their integration loss during the signal processing related with the threshold voltage level of matched filter . Finally this paper extended toward MIMO radar detection performance for moving target under the condition of unknown parameters or other fluctuating model.

Title:	ANALYSIS AND MATHEMATICAL MODELLING OF SPACE VECTOR MODULATED DIRECT CONTROLLED MATRIX CONVERTER
Author:	RUZLAINI GHONI, AHMED N. ABDALLA
Source:	Journal of Theoretical and Applied Information Technology Vol 21. No. 1 -- 2010
Abstract	Matrix converters as induction motor drivers have received considerable attention in recent years because of its good alternative to voltage source inverter pulse width modulation (VSI-PWM) converters. This paper presents the work carried out in developing a mathematical model for a space vector modulated (SVM) direct controlled matrix converter. The mathematical expressions relating the input and output of the three phase matrix converter are implemented by using MATLAB/SIMULINK. The duty cycles of the switches are modeled using space vector modulation for 0.5 and 0.866 voltage transfer ratios. Simulations of the matrix converter loaded by passive RL load and active induction motor are performed. A unique feature of the proposed model is that it requires very less computation time and less memory compared to the power circuit realized by using actual switches. In addition, it offers better spectral performances, full control of the input power factor, fully utilization of input voltages, improve modulation performance and output voltage close to sinusoidal

Title:	A NEW INCREMENTAL GENETIC ALGORITHM BASED CLASSIFICATION MODEL TO MINE DATA WITH CONCEPT DRIFT
Author:	P.VIVEKANANDAN , Dr. R. NEDUNCHEZHIAN
Source:	Journal of Theoretical and Applied Information Technology Vol 21. No. 1 -- 2010
Abstract	In a database the data concepts changes over time and this is called concept drift. Genetic algorithm is widely used for mining classification rules. If the data set is of three or four years old, the mined rules may not reflect the current concept due to concept drift. Applying the incremental genetic (IGA) algorithm in a batch mode can mine accurate rules reflecting the current concept. But applying genetic algorithm without monitoring for a change in an incremental manner repeatedly on arriving data will result in an unnecessary increase in the learning cost. There is also another problem, Due to change in the data distribution some of the rules which are generated may be lost when we apply genetic algorithm in an incremental fashion. In this paper a new incremental genetic algorithm is proposed to rectify the above problems. The New IGA applies the Genetic algorithm iteration step only when required, so that learning cost may be reduced. The new method also keeps track of the rules which are generated earlier and which would have been lost due to change in data distribution. In the proposed method each record of the incoming dataset is monitored. If they are correctly classified they are dropped and misclassified records are added to a window. When the window is full, the genetic algorithm is applied to the records in the window and new rules are generated based only on the misclassified examples and on the examples of new classes. The invalid rules are replaced with the newly generated valid rules. The new method ensures that the next iteration of genetic algorithm is called only when there is a concept drift or when there is a change in the data distribution and sufficient number of records is available. This will reduce the learning cost particularly when there is no concept drift or when there is a slow drift and also ensures that no rule is lost due to change in data distribution.

Title:	DEVELOPMENT OF E-HEALTH APPLICATION FOR RURAL COMMUNITY OF BANGLADESH
Author:	DEBASHISH DAS
Source:	Journal of Theoretical and Applied Information Technology Vol 21. No. 1 -- 2010
Abstract	Bangladesh is a developing country. In developing countries, there is a digital divide between rural and urban areas. We need to provide locally relevant ICT services to overcome these divisions. Traditional software development methods are not suitable for developing the software of rural areas because they cannot serve the unique needs and complexities of such areas. I have tried to find the most appropriate way to engineer suitable software applications for rural communities of Bangladesh. I have developed a methodological framework for creating software applications for rural community. Socially structured computing framework to create software applications using the principle of action research and participative Design Guide as the best practices that helped me address all the problems that affect the success of the application. On the validity of the framework, I show that by using it to create Telemedicine Communicator (TC). TC is a prototype system for remote consultations in health for rural communities. It allows for communication between a small hospital in a village and a bigger hospital in neighboring village. It uses Voice over Internet Protocol (VoIP) combined with a store and forward approach to communications. TC can be tested over a Wireless Fidelity (wireless) network as well. Within social consciousness, it is suitable for the local development of relevant applications for rural areas of Bangladesh. I found that TC is an improvement of the solution of telemedicine in the community of destiny. Using this approach also led to a lot of knowledge about best practices for ICT development projects. I am also proposing that VoIP and Wi-Fi technology is relevant to rural areas and that the liberalization of telecommunications in Bangladesh is still needed to promote technological development in rural and under serviced areas.

Title:	E-DEMOCRACY IN MIDDLE EAST: HARD TO APPROACH
Author:	EYAS EL-QAWASMEH, SUHAIL OWAIS
Source:	Journal of Theoretical and Applied Information Technology Vol 21. No. 1 -- 2010
Abstract	The paper will explore the key benefits and challenges in advancing e-Government for democratic participation and social inclusion, particularly from a Middle Eastern regional perspective (i.e., Hashemite Kingdom of Jordan). The use of online Internet services for applying e-democracy is studied with many clarifying comments and obstacles. The authors suggest that the implementation of e-Democracy requires an environment of confidence that must be created. In addition, a transition period of “real democracy” must be implemented first for some time. Some of the problems with implementing of e-Democracy in the Middle East are presented. In addition, many observations and examples are given to verify the notes of the authors.

Author:	D.KALYANAKUMAR, Dr.V.KIRBAKARAN, K.RAMASH KUMAR
Source:	Journal of Theoretical and Applied Information Technology Vol 21. No. 1 -- 2010
Abstract	This paper presents an investigation of Hybrid Seven-Level (HSL) H – bridge Inverter is used in a Distribution Static Compensator (DSTATCOM) in Power System (PS), making use of HSLI benefits of low harmonics distortion, reduced number of switches to achieve the seven- level inverter output over the conventional cascaded seven level inverter and reduced switching losses. In order to improve the power factor, compensate the reactive power and suppress the total harmonics distortion (THD) drawn from a Non-Liner Diode Rectifier Load (NLDRL) of DSTATCOM, we propose a Sub-Harmonics Pulse Width Modulation (SHPWM) technique is used as control for the switches of HSL H – bridge Inverter. The D-Q reference frame theory is used to generate the reference compensating currents for DSTATCOM and proportional and integral (PI) control is used for capacitors dc voltage regulation for DSTATCOM. A HSL H – bridge Inverter is considered for shunt compensation of a 4.5 kV distribution system. The results are validated through MatLab/Simulink simulation software
