The purpose of this work was to determine the structure of latent factors, to identify and analyse groups of game tasks under specifi c attributes and variables, to classify the tasks into relatively homogenous groups, and to determine the differences between the acquired groups of tasks. In order to achieve the above mentioned it was necessary to construct a measuring instrument (questionnaire...

Off recent, there has been an increased interest in reducing computing processors powers and improve system throughout. This has led to the design and redesign of multicore processors that have been rolled out to meet the ever increasing computational problems. Complex problems have emerged in the IT and ICT world which have led to the evolution of traditional computing environments in order to...

Numerous studies have been carried out to determine the effect of various types of bone transplants on the healing pattern of experimentally produced defects in animals (Maatz, Lentz and Graf 1954; Burwell 1963; Heipel, Chase and Herndon 1963; Melcher and Irving 1963; Buring and Urist 1967; Raina 1968). These have repeatedly shown that autogenous bone grafts are better than homogenous and heter...

We study the linkage classes of homogeneous ideals in polynomial rings. An ideal is said to be homogeneously licci if it can be linked to a complete intersection using only homogeneous regular sequences at each step. We ask a natural question: if I is homogeneously licci, then can it be linked to a complete intersection by linking using regular sequences of forms of smallest possible degree at ...

Clustering of the texture images is a demanding part of multimedia database mining. Most of the natural textures are non-homogenous in terms of color and textural properties. In many cases, there is a need for a system that is able to divide the non-homogenous texture images into visually similar clusters. In this paper, we introduce a new method for this purpose. In our clustering technique, t...

Anomaly detection in large populations is a challenging but highly relevant problem. The problem is essentially a multihypothesis problem, with a hypothesis for every division of the systems into normal and anomal systems. The number of hypothesis grows rapidly with the number of systems and approximate solutions become a necessity for any problems of practical interests. In the current paper w...

We prove that a homogeneous Banach space B on the unit circle T can be embedded as a closed subspace of a dual space ΞB contained in the space of bounded Borel measures on T in such a way that the map B → ΞB defines a bijective correspondence between the class of homogeneous Banach spaces on T and the class of prehomogeneous Banach spaces on T. We apply our results to show that the algebra of a...

Networks have been extensively used to model various complex systems such as online social networks, co-authorship and citation networks and gene networks. Due to different kinds of variations such as temporal, spatial, topic and phenotypic variations, several variants of the same network may exist. For several practical problems, identifying the nodes that are changing between the networks pro...

Abstract—In this paper an unsupervised color image segmentation method is suggested. Color image segmentation is an important but still open problem in image processing. At first, FCM is applied to the image and the cluster centers are obtained. Quite similar to the famous TSK fuzzy control model, we form several rules (IF-THEN like) for pixel classification. The results obtained from the rules...
