One of the difficulties that occur in the model is to decide the weights of quality characteristics. This is due to the interrelations existence among the quality factors based model ISO 9126. Each of these characteristics can influence or even contradict each other. The interrelations existence among the factors affects the weight of characteristics software quality, and will affect the software quality calculation. Therefore, researchers will integrate DEMATEL and ANP methods for calculate the weight of characteristics software quality based model ISO 9126. DEMATEL method used to calculate sum of influences for each characteristics model ISO 9126, while the ANP method used to calculate local weights and global weight for each sub characteristics model ISO 9126. Results from this study is the value of local weights for each of the characteristics of ISO 9126, and global weights for each sub characteristics ISO 9126 which represent the level of importance of the characteristics and sub characteristics ISO 9126.

This paper presents an attractive approach for teaching the large three-phase synchronous generator under unbalanced steady-state condition of the 500 kV EHV Jawa-Madura-Bali (or Jamali) system to which it is connected using Matlab's Graphical User Interface (GUI) capability. Whereas two unbalanced steady-state conditions of the grid are obtained by setting all of IBTs (or inter bus transformers), the Jamali's grid loads, into load imbalance of 5% and 10%. The main motivation for such a study is to develop user-friendly software for better teaching the behavior of the generator which is connected to the grid when unbalanced loads are present. An example is given to demonstrate the usefulness of the developed tool.

This paper proposes a quadratic programming for solving the dynamic direct current optimal power flow (DDCOPF). The DDCOPF solves OPF with multi load levels in which ramp rate of committed units become coupling between two series load levels. To overcome this problem, a very large matrix may be required. The more number of load levels are considered, the larger matrix will be used. Consequently, it may take long computation time to solve. Therefore, the DC load flow is preferable than AC load flow. To show the effectiveness of the proposed approach, IEEE 14 bus test system is used. In addition, application of the proposed approach to real system Jawa Bali 500 kV 25-bus is presented.

In this paper, an online decentralized multisensor data fusion algorithm facilitated by middleware networked using CORBA event channel is proposed, in order to deal with simplifying problem in sensor registration and fusion for vehicle state estimation. The networked based navigation concept for Autonomous Underwater Vehicle (AUV) using several sensors is presented. A simulation of various application scenarios are considered by choosing several parameters of UKF, i.e. weighting constant for sigma points and square root matrix. Normalized mean-square error (MSE) of Monte Carlo simulations are computed and reported in the simulation results. Furthermore, the middleware infrastructure based on Open Control Platform (OCP) to support the interconnection between the whole filter structures also reported.

In power system dynamic studies, it is necessary to represent induction motor loads with a standard reduced order model in order to reduce computational requirements. A third-order model, neglecting the stator transients, is often used. In this paper, the third-order model is further simplified into two second-order models, called as slip-flux-magnitude and slip-flux-angle models. The model derivations are given in detail. The dynamic responses of both models are compared with the higher third-order model for the cases of small and large horse power induction motor loads. The study results show that the slip-flux-angle model gives better approximation of the third-order model.

This paper presents the design and modeling of a portable pico linear permanent magnet generator for the application of wave energy conversion system. Two types of generator technology namely the rotary and linear are identified but due to the high maintenance and low efficiency of rotary, linear generator is preferable. Three linear permanent magnet generator designs with different types of permanent magnet shape have been proposed. Preliminary results for the air gap distribution and open circuit test are demonstrated and discussed are shown to be as expected.
