In the paper a design and principle of operation of the system facilitating communication between hearing and deaf people is presented. The system has a modular architecture and consists of main application, translation server and two complementary databases. The main application is responsible for interaction with the user and visualization of the sign language gestures. The translation server carries out translation of the text written in the Polish language to the appropriate messages of the sign language. The translation server is composed of facts database and translation rules implemented in the Prolog language. The facts database contains the set of the lexemes and their inflected forms with a description of the semantics of units. The translation rules carry out identification and analysis of basic structures of the Polish language sentence. These basic structures are related to the sentence creation function of the verb predicate. On the basis of this analysis equivalent translation of text into the sign language is realized. Translated text in the form of metadata is passed to the main application, where it is translated into the appropriate gestures of the sign language and face mimicry. The gestures in the form of 3d vectors and face mimicry are stored in the main database as binary objects. The authors intend to apply the translation system in various public institutions like hospitals, clinics, post offices, schools and offices. © 2013 Springer-Verlag.

The biometric menagerie-A fuzzy and inconsistent concept

This paper proves that in iris recognition, the concepts of sheep, goats, lambs and wolves-as proposed by Doddington and Yager in the so-called Biometric Menagerie, are at most fuzzy and at least not quite well defined. They depend not only on the users or on their biometric templates, but also on the parameters that calibrate the iris recognition system. This paper shows that, in the case of iris recognition, the extensions of these concepts have very unsharp and unstable (non-stationary) boundaries. The membership of a user to these categories is more often expressed as a degree (as a fuzzy value) rather than as a crisp value. Moreover, they are defined by fuzzy Sugeno rules instead of classical (crisp) definitions. For these reasons, we said that the Biometric Menagerie proposed by Doddington and Yager could be at most a fuzzy concept of biometry, but even this status is conditioned by improving its definition. All of these facts are confirmed experimentally in a series of 12 exhaustive iris recognition tests undertaken for University of Bath Iris Image Database while using three different iris code dimensions (256x16, 128x8 and 64x4), two different iris texture encoders (Log Gabor and Haar Hilbert) and two different types of safety models. © 2013 Springer-Verlag Berlin Heidelberg.

We present a design and simulation results of an integrated circuit dedicated to recording and detection of a broad range of biomedical signals. The chip is designed in a 180nm CMOS technology and occupies 1.5×1.5 mm~2. It consists of 8 channels responsible for amplification, filtration, and detection of biomedical signals. Main parameters of the single recording channel such as a voltage gain, frequency band, voltage offset, and a threshold detection, are controlled independently by on-chip digital registers. The single recording channel is supplied from ±0.9 V and consumes about 8 μW of power.

A novel derivative-free algorithm for solving quasi-linear systems is presented. It resembles 'classical' optimization approach but greatly simplifies computation, resulting in fast execution and numerical stability. Though the global convergence cannot be guaranteed, it turns out that the presented algorithm finds a solution as successfully as other commonly accepted methods. The algorithm is clearly developed and mathematically founded, and its properties are examined by comparisons with other methods. © 2013 SRCE University Computing Centre, University of Zagreb.

There are many types of bio-signals with various control application prospects. In this work possible control application domain of electroencephalographic signal obtained from an easily available, inexpensive EEG headset - Emotiv EPOC was presented. This work also involved application of an embedded system platform. That solution caused limits in choosing an appropriate signal processing method, as embedded platforms characterise with a little efficiency and low computing power. Potential implementation of the embedded platform enables to extend the possible future application of the proposed BCI. It also gives more flexibility, as the platform is able to simulate various environments. In this work traditional, statistical methods were neither used nor described.

In this paper a hardware implementation of the state-of-the-art PBAS (Pixel-Based Adaptive Segmenter) foreground object detection algorithm in FPGA is presented. This background modelling and subtraction technique is using novel ideas which improve the detection results. In this work a research is presented that determines which parts of the original algorithm need to be adjusted and modified to allow hardware implementation. A comparison is presented how this modifications influence the results accuracy compared to the original software implementation and other algorithms. An example working system based on the proposed module using the evaluation board with Virtex 7 device is also presented. This is the first reported FPGA implementation of this algorithm.

In this paper we present a method of transmitting routing updates in IPv6 networks. Routing protocols that use discrete packets to send/receive routing updates are susceptible to instability in a limited bandwidth or lossy links environment. We study and compare our method with OSPF and EIGRP and show that it stabilizes more rapidly. By design, our method is robust and it is not susceptible to bandwidth limitation and to the degree of lost packets like other routing protocols. © 2012 Dunarea de Jos University.

Usually when modeling a real process the effects of nonlinearities must be taken into account. A road traffic sector is one such process. Considering it from a macroscopic point of view, the sector is modeled both as a nonlinear and as a linearized process. An I/O model is proposed and a RST control algorithm is used to ensure the imposed performances for the closed loop system. The robustness of the system is obtained by determining the modulus margin and based upon it the admissible nonlinearities are analyzed in order to determine the limits between which the system maintains its stability. ©2012 IEEE.

In this paper a method for execution programming of data-intensive applications is presented. The method is based on storage Quality of Service (SQoS) provisioning. SQoS provisioning uses the semantic based storage monitoring based on a storage resources model and a storage performance management. Test results show the gain for the execution time when using the QStorMan toolkit which implements the presented method. Taking into account the SQoS provisioning opportunity on the one hand, and the increasingly growing user demands on the other hand, we believe that the execution programming of data-intensive applications can bring a new quality into the application execution. © 2012 - IOS Press and the authors.
