Recent wireless networks offer more bandwidth than ever. High quality services are developed and provided by the operators, the number of users is constantly increasing. As the transferred data and the number of terminals are growing, the network providers have to face the increasing complexity of the network management and operation tasks. In this paper we observe one of the main problems that arise in a wireless network, the tracking of the users' mobility. We compare in detail the accuracy versus the complexity of mobility models serving for location prediction.

Image auto-annotation methods perform the description previously unseen images with a set of words, based on previously shown examples. This is a relatively new paradigm in image processing research domain. Capillaroscopy is a branch of medicine focusing on analysis of vascular changes. Among others, it is a very helpful tool in diagnosis of many rheumatic diseases. The paper presents a preliminary research on usage of image auto-annotation methods for the computer-aided diagnosis from capillaroscopy images.

This article present outstanding results given by the new application of artificial immune systems in trend change detection in time series. Author's system (GRASICA3), has been evaluated on a financial time series containing daily quotas of the main index of the Warsaw's stock exchange (WIG) and additionally on a synthetic time series generated using the Monte Carlo method. Very good results which have been obtained (>60% of accuracy in trend change signals) are compared to results of other systems known from a bibliography, designed by Gutjahr and Kingdon. In the next stage the author provides a comparison of the GRASICA3 results to results given traditional statistical modeling methods such as, a very popular Box-Jenkins and Arima X-12 algorithms.

This paper investigates mobility management strategies from the point of view of their need of signalling and processing resources on the backbone network and load on the air interface. A method is proposed to model the serving network and mobile node mobility in order to be able to model the different types of mobility management algorithms. To obtain a good description of the network we calculate parameters from given topologies that we think are the most important ones. Mobility approaches derived from existing protocols and other, possible mobility scenarios are analyzed and their performance is numerically compared in various network and mobility scenarios. The aim is to give general designing guidelines for the next generation mobility managements on given network and mobility properties.

In recent years, various systems based on electronics, such as cars, computers and robots have been getting into our daily lives. Unfortunately, asymmetrical relationship exists between human and such systems, imposing burdens especially on elderly or handicapped persons. In order to solve various problems for balancing such asymmetrical relationship, humatronics is proposed. Main purpose of humatronics is to establish the symmetric interaction between human and electronic systems by giving the systems the capability of understanding humans. Another important factor for humatronics is computer networks, over which the systems can share knowledge, information, and experiences. This paper introduces the concept of humatronics and key technologies for realizing it. A prototype system that is currently developed based on the concept of humatronics is also introduced.

Predictive maintenance is a promising maintenance strategy. However, existing solutions are isolated from enterprise systems and limited to specific applications. A predictive maintenance framework that integrates the diversity of existing techniques for equipment failure predictions and that incorporates data both from machine level and the upper enterprise level is still missing. We envision the development of a predictive maintenance framework that is characterized by a high degree of automation and the possibility to use state-of-the-art prediction methods. We attempt to create an open architecture that enables third-party suppliers to integrate their specialized prediction components into our framework. In this paper we analyze the requirements and introduce the initial architecture associated with such a predictive maintenance framework, which is being realized in a joint project with SAP Research.

One of the intriguing applications of immune-inspired negative selection algorithm is anomaly detection in the datasets. Such a detection is based on the self/nonself discrimination and its characteristic feature is the ability of detecting nonself samples (anomalies) by using only information about the self or regular, samples. Thus the problem space (Universe) is splitted into two disjoint subspaces: One of them contains self samples and the second is covered by the samples which activate the detectors generated by the negative selection algorithms. Hence, the efficiency of negative selection algorithms is proportional to the degree of coverage (by the detectors) of nonself subspace. In this paper, we present a simple method of increasing the coverage for real-valued negative selection algorithm.

This paper presents a hybrid system for word recognition. It is based on a modification to the view-based approach presented in authors' previous works. The algorithm is based on recognizing the whole words without separating them into letters. The characteristic vectors taken from both top and bottom views of the image are processed with the method of Toeplitz matrices. The obtained series of minimal eigenvalues is used for classification. The procedure of classification involves arrays of neural networks. Each network in the array is responsible for detecting one class. The results of the experiments on a set of common English words are presented.

In this paper, the problem of semi-supervised handwriting segmentation into isolated character images is considered. Semi-supervised segmentation means here that the character sequence constituting a word presented on the image is known, but the character boundaries are not given and need to be automatically determined. The semi-supervised word segmentation can be useful in analytic writer-dependent approach to handwriting recognition, where the training set for personalized character classifier must be created for each writer from the text corpus consisting of text samples of an individual writer. The method described here over-segments the word images into sequences of graphemes in the first step. Then such grapheme sequences subdivision is sought, which results in the hypothetical character images sets maximizing average similarity in subsets corresponding to characters from the alphabet. It leads to the combinatorial optimization problem with enormously large search space. The suboptimal solution of this problem can be found using evolutionary algorithm. The sample character images extracted in this way can be used to train character classifiers. Some preliminary results of handwriting segmentation are presented in the paper and compared with fully supervised segmentation carried out by a human.

This research work aims to investigate the performance of a suggested wavelet based image compression system. The scheme of the proposed system utilizes 9/7 biorthogonal wavelet transforms to decompose the image signal, then uses run-length coding, with a little modification, to compress the detail sub-bands. A hierarchal quantization scheme was applied to reduce the number of bits required to encode the wavelet coefficients. The test results indicate that the proposed compression scheme shows good performance aspects in addition to its simplicity.
