    There are several risk-sensitive industries-like air traffic, nuclear power generation, dangerous chemical processes, etc. The technical solutions used are usually well approved and widely known; the occasional problems usually originate from the not-careful-enough design, the insufficient risk assessment, the unsatisfactory training and mismanagement. With proper operation and waste management th... View full abstract»

    Aristotelian syllogism is traditional logic which is considered as un-formalized normally. The paper formalized Aristotelian syllogism as the forms of propositions with all the rules for getting the valid forms (figures).Based on the results, an automatic system are developed using VC++ and MFC (Microsoft Foundation Class). For any Aristotelian syllogism which are divided into 4 types named as 4 f... View full abstract»

    This paper presents the application of fuzzy logic controller (FLC) to a grain dryer plant. Grain dryer plant is very difficult to control due to long delay process and non-linear behaviour. The controller consists of two inputs; error between actual grain moisture content and set-point, and rate of change of error. There is one fuzzy output that is used to drive the grain flow rate.

    A Low cost Navigation Solution has developed for Unmanned Land vehicle (ULV) by using GPS & one ABS Sensor. Two IR Modules are integrated to detect obstacles in the path of movement. This combined arrangement is simple and gave satisfactory results at smooth surfaces. At rough surfaces results are very poor and vehicle lost its calculated path due to change of direction of front wheel. Presenc... View full abstract»

    In recent years, Particle Swarm Optimization (PSO) has been used in data mining, feature extraction and other optimization based applications. Time to time, a number of researchers have suggested modifications to the basic PSO. Although this optimization technique finds good solutions much faster than the traditional and evolutionary algorithms, they suffer from a major drawback of premature conve... View full abstract»

    Warnings for evacuation and other measures from the distant early warning system (DEWS) for tsunami in the Indian Ocean, are now already in place. Recently, attempts have been made by the author to evaluate the differences in the affects on adjacent beaches for the 2004 tsunami, arising from the orientation and other features for each beach. Consequently, it is now feasible to consider more specif... View full abstract»

    Risk assessment is often done by human experts, because there is no exact and mathematical solution to the problem.Usually the human reasoning and perception process cannot be expressed precisely. This paper propose a genetic programming approach for risk assessment. Preliminary results indicate that genetic programming methods are robust and suitable for this problem when compared to other risk a... View full abstract»

    Genetic algorithms are robust parallel calculation methods based on natural selection. Various crossover and mutation methods to accomplish Genetic Algorithm (GA), namely, single point, multipoint, uniform, greedy, migration, and on-demand etc.; exist. However, these mechanisms are static in nature. This paper presents a dynamic crossover (DC) mechanism. We investigate its performance by implement... View full abstract»

    The Kohonen self organizing map is widely used as a popular tool in the exploratory phase of data mining. The SOM (self organizing maps) maps high dimensional space into a 2-dimensional grid by placing similar elements close together, forming clusters. Recently research experiments presented that to capture the uncertainty involved in cluster analysis, it is not necessary to have crisp boundaries ... View full abstract»

    Modern artilleries have the capability to hit targets with high level of accuracy. However, a problem arises with the current firing procedure when neither the field observer nor the fire direction center is available to support the artillery crew with the necessary information. In this situation, the detection of environmental conditions would involve a number of uncertainties and due to this rea... View full abstract»

    In this paper we propose a multistage computational procedure for partitioning of large data sets and for segmentation of images. In the first step the original ldquorawrdquo data set (or the set of pixels from a given image) is compressed by use of the neural-gas unsupervised learning algorithm into compressed information model (CIM) that contains small predefined number of neurons. In the second... View full abstract»

    Handling of many-objective problems is a hot issue in the evolutionary multiobjective optimization (EMO) community. It is well-known that frequently-used EMO algorithms such as NSGA-II and SPEA do not work well on many-objective problems whereas they have been successfully applied to a large number of test problems and real-world application tasks with two or three objectives. The main difficulty ... View full abstract»
