When designing a system in which sensors are randomly deployed in a circular region to detect a signal emitter in a random location, the system designer may consider the least favorable distribution for the emitter lo...

In this paper, we present an algorithm to remove Salt and Pepper noise from grayscale images. It is an enhanced adaptive median filtering algorithm which initially calculates median without considering noisy pixels in the processing window. If the noise-free median value is not available in the maximum processing window, the last processed pixel value is used as the replacement. Moreover, in extreme situations such as noise corrupted pure black and white images, a threshold value is used to determine the pixel value. Experimental results show that our algorithm can perform better than the other non-linear filters, suppressing noise level more than 90% while preserving visual quality and necessary details of the image.

Withthe ever-increasing popularity of cell phone devices, text based services on such devices are becoming more and more popular. Problems with traditional keypads primarily lie withthe placement of the letters alphabetically on the keys. this configuration is comparatively easy for the users to remember but can greatly limit the flexibility of finger movement, as well as require a higher number of keystrokes and key jamming. In attempting to resolve these issues, a novel innovative solution is proposed here, focusing on boththe structure of human finger movements and ordering of letters on the keys based on their frequency of use. Simulations and performance measurement of our represented system have shown rapid reduction in key jamming by up to 57 percent, improvements in flexibility of finger movement by up to 11.5 percent and reduction in number of keystrokes by up to 34 percent.
We propose a new multi-target tracking (MTT) algorithm capable of tracking an unknown number of targets that move close and/or cross each other in a dense environment. the optimal Bayes MTT problem is formulated in th...

Moment-based filters, such as the Probability Hypothesis Density (PHD) filter, are an attractive solution to multitarget tracking. However, an underlying assumption for the PHD filter is that each measurement is eithe...

A Type-2 Fuzzy logic controller adapted with genetic algorithm, called type-2 genetic fuzzy logic controller (T2GFLC), is presented in this paper to handle uncertainty with dynamic optimal learning. Genetic algorithm is employed to simultaneous design of type-2 membership functions and rule sets for type-2 fuzzy logic controllers. Traditional fuzzy logic controllers (FLCs), often termed as type-1 fuzzy logic systems using type-1 fuzzy sets, cannot handle large amount of uncertainties present in many real environments. therefore, recently type-2 FLC has been proposed. the type-2 FLC can be considered as a collection of different embedded type-1 FLCs. However, the current design process of type-2 FLC is not automatic and relies on human experts. the purpose of our study is to make the design process automatic. the evolved type-2 FLCs can deal with large amount of uncertainties and exhibit better performance for the mobile robot. Furthermore, it has outperformed their type-1 counterparts as well as the traditionally designed type-2 FLCs.

the bow-tie structure is frequently cited in the literature of the World Wide Web and in many other areas, such as metabolic networks, but it has never been precisely defined, so that to some extent the concept being discussed remains vague. this paper first provides a formal definition of a bow-tie structure relative to a given strongly connected components. that definition details distinctions which are not usually made, such as the difference between intendrils and outtendrils. theorems and algorithms are then provided to justify and support the definition. Finally a bow-tie decomposition algorithm is developed and illustrated. the algorithms have also been implemented and tested on a university domain.

Many colleges and universities are initiating or expanding their online degree programs. the shift in course delivery mode requires new approaches to assuring academic quality. To achieve continuous improvement in Information and Communication Technologies (specifically online learning), a research-based training, mentoring, and evaluation system was designed by a faculty team at Park University (USA). this session describes the development and successful use of three different quality assurance methods that can be adapted by institutions with varying resources, enrollments, and training and development needs. We will examine and discuss how efficient and effective systems can produce constructive evaluation and retention of online instructors in addition to desirable outcomes for students and institutions.

the paper deals with a problem of searching a suitable form of modern language learning for a specific target group. the technical core of the solution should be the usage of information and communication technologies (ICT). the problem is solved from the point of view of the Department of communication and information systems. the starting point of the paper is a characteristic of the specified target group in relation to the status and needs of its language learning. the next part of the text is focused on a proposal for an appropriate language education which is partly based on the distance learning form. As examples the author selects from his point of view the most important sub-problems of language education of the academic staff. Finally, the importance of language competencies of the academic staff is emphasized.
