In the electricity deregulation, the electricity consumption of consumers depending on the electricity prices will change because the electricity prices are expected to fluctuate according to the market conditions. Therefore, the fluctuation of the electricity consumption can cause difficulty of distribution system operation, e.g. minimizing the distribution line losses, improving the voltage profile,...
Recently in Japan, a deregulation of electricity market is being extended and retailers are expected to supply the electricity to consumers. Moreover, an energy management system enables the consumers to easily manage their energy consumption according to the electricity prices. This means that a large number of decision makers who manages electricity energy will be in the electricity market. In order...
At present, some training tools for endoscopic surgery have been commercialized such as box simulator and virtual training simulator. These training tools enable a trainee to practice various operation without any risks of a patient and have been utilized by unskilled surgeons in medical institutions. However, more effective training environments have been required by the doctors who engage in medical...
Identifying similar structures in proteins has emerged as one of the most attractive research topics in the post-genome era. Protein structure alignment, which is similar to sequence alignment, identifies the structural homology between two protein structures according to their three-dimensional conformation. One of the simplest yet most robust techniques for optimizing protein structure alignment...
By improvements of ICT (Information and Communications Technologies), a lot of advanced high speed communication standards such as 3G (3rd generation mobile telecommunications), LTE (Long Term Evolution) and High speed WLAN (Wireless Local Area Network) have been developed. Recently, most devices destined for consumer use, equip more than one communication interface based on the above high speed communication...
There is increasing demand for accurate short-term forecasting of weather conditions at specified locations. This demand arises partly from the growing numbers of renewable energy facilities. In order successfully to integrate renewable energy supplies with grid sources, the short term (e.g. next 24 hrs) output profile of the renewable system needs to be forecast as accurately as possible, to avoid...
In this paper, we focus on evolutionary optimization of multi-agent behavior. There are two representative models for multi-agent control, homogeneous and heterogeneous models. In the homogeneous model, all agents are controlled by the same controller. Therefore, it is difficult to realize complex cooperative behavior such as division of labors. In contrast, in the heterogeneous model, respective...
There is a need of surgery workflow analysis to increase an efficiency of advanced medical care. Surgical Operations have been recorded by several sensors for such as postoperative analysis and incidents detection. In particular, surgical video recording is commonly used, so there are some audio-visual recorded data, and they are useful to obtain a better understandings and description of advanced...
Passing the university entrance examination is a crucial step in student's life because it opens the vistas of higher education in professional development. It is very competitive to a certain degree so students try their luck with necessary preparation. Those who not prepared well, they fail it. Kankor is one such university entrance examination in Afghanistan. However, majority of talented students...
The Gait recognition is the 2nd generation of biometric identification technology which aims to identify people at a distance by the way they walk. Due to the fact that there has been increasing research interest in the identification of an individual in access controlled environments such as the airports, banks and car parks, it has been observed that the effective human gait recognition plays a...
The social community in open source software developers has a complex network structure. The network structure represents the relations between the project and the engineer in the software developer's community. A project forms some teams which consist of engineers categorized into some task group. Source Forge is well known to be one of open source websites. The node and arc in the network structure...
This paper proposes a non-Gaussian approach for biosignal classification based on the Johnson SU translation system. The Johnson system is a normalizing translation that transforms data without normality to normal distribution using four parameters, thereby enabling the representation of a wide range of shapes for marginal distribution with skewness and kurtosis. In this study, a discriminative model...
In multi-relational data mining (MRDM), there have been proposed many methods for searching for patterns that involve multiple tables (relations) from a relational database. In this paper, we consider closed pattern mining from a multi-relational database (MRDB). Closed patterns, a.k.a. concept intents, give the condensed representations of frequent patterns, without losing any information, and they...
The paper presents adaptive particle swarm optimization with multi-dimensional mutation (MM-APSO), which can perform move efficient search than the conventional adaptive particle swarm optimization (APSO). In particular, it can solve non-separable fitness functions such as banana functions with high accuracy and rapid convergence. MM-APSO consists of APSO and additional two methods. One is multi-dimensional...
The grant for the research gives the researcher the important opportunity to make fruitful research results. Recently, the notification of the government grants and some Foundation grants in the various fields informs the researchers through Internet. However, the notification provided through Internet includes ambiguous and complex. The researchers will fail to notice the grant information which...
