Steering grip force data is obtained by using two resistive force sensors attached to the steering wheel and connected to a personal computer with the aid of a data acquisition module. The alertness of the driver is then assessed by utilizing change detection algorithm based on log-likelihood ratio. The aforementioned system is a module of a driver safety system for smart vehicle, which uses sensor fusion technology to prevent driver-related road accidents.","PeriodicalId":239300,"journal":{"name":"Proceedings.

The UC and ELD problems are to decide when and which generating units to commit and decommit, in order to minimize the total fuel cost over specified period subject to a large number of difficult constraints. Lagrangian relaxation (LR) has been widely used to solve UC and ELD. Recently bundling method (BM) has appeared to be one of the best multipliers updated techniques for LR. This method has promising and the fastest convergence characteristics for UC and ELD problems. For that reason, this paper is to solve the UC and ELD problems via LR, BM and interior point method. This paper explores also the best possible way of updating Lagrangian multipliers with minimum computation time using fast programming techniques.","PeriodicalId":239300,"journal":{"name":"Proceedings.

The structure accepts declarative global specification of constraints including user-defined constraint, and an efficient representation that permits localized constraints checking. A new method called \"detection\" is added to the structure to check the status of violation of the relations in an object-oriented database. The new approach is demonstrated using ALICE rule. The notion of the constraints is used to define the connectivity between objects required for the valid expression of constraint and rule conditions. The event in an event-condition-action (ECA) rule that defines the active behavior of an application specifies an operation to be monitored, such as modifying a data value. The semantic analysis process applies a concept known as object-centered conditions during the compilation of ALICE rules to detect semantically incorrect rules at compile time.","PeriodicalId":239300,"journal":{"name":"Proceedings.

The heart sounds is a non-stationery signal, thus it is very important to study the frequency and time information. One of the time-frequency analysis methods is short time Fourier transforms. However, the STFT analysis is limited by the time and frequency resolution. The wavelet transform was introduced to curb the resolution problem in STFT. The wavelet transform is a multi-resolution time-scale analysis that gives high resolution for low frequency components and low resolution for high frequency components. Since majority of heart sounds component lies in low frequency, thus the application of wavelet transform to heart sounds is very suitable. Results in time-frequency representation clearly show that the wavelet transform is capable to distinguish between the normal with a few types of abnormal heart sounds. The murmurs caused by particular heart diseases such as aortic regurgitation, aortic stenosis, mitral regurgitation, mitral stenosis, pulmonary regurgitation and tricuspid regurgitation were clearly shown under continuous wavelet representation.","PeriodicalId":239300,"journal":{"name":"Proceedings.

This paper describes how CORBA standard was successfully used in developing a distributed stock exchange application, a typical three tiers (clients, brokers, stock exchange) application that has many distributed components and a high database hit rate. The Kuala Lumpur stock exchange (KLSE) was taken as a model of study in developing this application. CORBA event service was heavily used to cater for the communication needs of this application.

Building up so many towers for power transmitting need a high expenditure. To overcome this problem, conductor as transmission line with capability to conduct more current is needed. Aluminum is a good current conductor; low in cost and lighter weight compare to copper. These advantages enhance the usage of aluminum conductor as overhead line of transmission system. But the weakness is on mechanical part, which is not practical to ambient condition. This paper focuses on the factors that influence the conductivity and current carrying capacity of aluminum conductor.

This paper presents an approach in using solar power to generate electrical energy in the future using an SPS 2000 (solar power satellite) rectenna. The suitable location of the rectenna in Malaysia has been identified. Spherical rectenna is chosen for optimized reception area and for ease of analysis. The amount of energy received by this rectenna is simulated using Visual Basic V.5.0. The latitude of the rectenna, rectenna radius, earth inclination, distance between rectenna and satellite and the time of the year of inception determine energy reception. The program also estimates the price per kWh of energy generated. However, this is not the real of electricity as the satellite and the transmitting costs were not considered in the calculation.","PeriodicalId":239300,"journal":{"name":"Proceedings.

However, these advances have their drawbacks as well, for example unauthorized tampering of images. Digital watermarking has emerged as a possible method to tackle these issues. A digital watermark is created by inserting a digital signal, or pattern within multimedia content. This embedded information can be used to determine whether the host data are being tampered with or not. This paper presents a review of watermarking where watermarking processes are described briefly and the appropriate properties for different applications are discussed.","PeriodicalId":239300,"journal":{"name":"Proceedings.
