    One of basic characteristics of regular bipedal walk of humanoid robots is the maintenance of their dynamic balance during the walk, whereby a decisive role is played by the unpowered degrees of freedom arising at the foot-ground contact. Hence, the role of Zero-Moment Point (ZMP) as an indicator of dynamic balance is indispensable. The paper gives a very detailed discussion of some basic theoreti... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (256 KB) | HTML iconHTML

    Co-evolutionary genetic algorithms are being used to solve the problems which are naturally distributed and need the composition of couple of elements or partial solutions to be solved. In these algorithms, the problem decomposes into several elements and for each element, a sub-population is regarded. These sub-populations evolve separately by considering the way of interactions among them. The g... View full abstract»

    In this paper I present an environment and algorithm for lazy (incremental) construction of multigram profile models as part of IR (information retrieval) training and exploitation processes. N-grams are traditionally used for natural language text models, but they can be also successfully used for domain independent document classification. I am demonstrating results of a prototype utility which ... View full abstract»

    This paper presents a method to estimate the system-state, especially the full position, of an autonomous vehicle using sensor data fusion of redundant position signals based on an extended Kalman-filter. The position is detected with the help of magnet sensors attached at the vehicle and a global camera signal with low resolution, similar to GPS. A lane marked with permanent magnets and an infrar...

    Hough transformation for finding straight line segments is well known in digital image processing. In this paper we have used Hough, houghline and houghpeaks functions for creating a new 4- dimensional parameter space named h_space for extracting rectangles in digital image. These parameters are coordinates of the center of a rectangle (intersection of diagonals), angle that the shorter edge makes... View full abstract»

    Assuming homogenity of the underlying statistics, interspike interval probability density functions recorded from behaving macaque monkeys are determined with a special statistical fitting method. The nature of the problem needed robust statistics approach, the results were validated with the Kolmogorov-Smirnov test. The results suggest that there is no single/universal interspike interval probabi... View full abstract»

    The idea of knowledge approximation is naturally rooted in the usual examples of approximation in our experience. More abstract approximation, at the levels of syntactic structures representing knowledge, is becoming a need in the existing knowledge management, addressing a variety of important issues. Here we propose a method and its implementation, which generalizes the unification method to the... View full abstract»

    Multi-agent Markov decision processes (MMDPs) are widely used for modeling many types of multi-agent systems. In this paper, two new algorithms based on learning automata are proposed for solving MMDPs and finding optimal policies. In the proposed algorithms, Markov problem is described as a directed graph. The nodes of this graph are the states of the problem, and the directed edges represent the... View full abstract»

    The paper introduces an approach for threshold potential optimization in the Pulse Coupled Neural Network (PCNN) to solve the quality of generated features for image recognition tasks. Threshold potential plays very important role because it provides and controls pulse effect of PCNN. The suitable control of pulse effect can improve dimension reduction of image classification space by PCNN that is... View full abstract»

    There are many different instruction scheduling techniques that are used in compilers today. The most frequently used one is the list scheduling. It is easy to implement and gives good results in most cases. It works on the basic block level. According to Fisher and Rau instruction level parallelism that can be achieved using this technique cannot be greater then 2. Architectures with deep pipelin... View full abstract»

    A picture is worth a thousand words. Yes, but which ones? Content-based image retrieval (CBIR) is the application of computer vision to the image retrieval problem. The image retrieval problem is the problem of searching for digital images in large databases. ldquoContent-basedrdquo means that the search will analyze the actual content of the image. The term dasiacontentpsila in this context might... View full abstract»

    A new approach to rate-control of visual communication is presented. This method is based on a recently introduced rate-distortion function for image compression systems. We show that this rate-distortion approach can be used to develop an efficient coding algorithm, suitable for wireless and Internet transmission. We demonstrate this approach for subband transform coding using the discrete cosine... View full abstract»
