Multimedia applications are characterized by an increased number of data transfers and storage operations. Appropriate transformations can be applied at the algorithmic level to improve crucial implementation characteristics. In this paper, the effect of data-reuse transformations on power consumption and performance of multimedia applications, realized on Application Specific Instruction set Processors (ASIP), is examined. An ASIP for multimedia applications, designed based on a complete methodologv is used to evaluate this effect. Results prove the efficiency of the ASIP solution and indicate that this approach can benefit, from such transformations, in terms of energy consumption and performance.

New tool for simulation of control systems (linear, non-linear and stochastic) is proposed. This software is written to simulate hybrid systems containing continuous and discrete (algorithmic) parts. Continuous processes are simulated using traditional structural schemes representing differential equations. Discrete link's are simulated by a Petri net, which is connected with continuous part of a system model through special, new introduced, modified transitions - "processes". The net may control processes - switch them on or off The continuous part sends real type values, which are used in guard expressions of "processes", into the net.

data analysis assumes a fundamental role in the environmental sampling to evaluated atmospheric pollution. We present a study about the comparison between two techniques of interpretation data. The first one is based on data acquired in the sampling. The second one is based on sampling added with both meteorological analysis and traffic flow evaluation. Among different air polluting, we analysed the particulate matter pollution because of recent epidemiological studies have found out about an association between particulate matter concentration and negative effects on the health [1]. The goals of our study consists in demonstrating as a correct air quality control is carried out through the acquisition of intelligentdata, that is the reason why only intelligentdata can characterize this dynamic phenomenon.

The possibility of artificial neural network usage for recognition of a signal of a multi-parameter sensor (MPS), described by different mathematical models, is described in this paper. These mathematical models are developed for the cases, when MPS conversion characteristics have positive derivatives, negative derivatives and derivatives of different sign at similar and opposite increasing of MPS output signal. The model of neural network, used for recognition, as well as achieved results of simulation modeling of a multi-parameter sensor signal recognition using MATLAB software are presented in the end of this paper.

This paper investigates the relationship between the social organisation of working environments and their relevance to system development. The objectives of this paper are therefore twofold. Firstly, it effectively analyses the social aspects of working practices using established techniques of ethnography. Such analysis provides a 'rich' and 'concrete' portrayal of the situation and thus helps systematic design of CSCW systems. Secondly, it uses meta-modelling in order to represent and model the findings of the ethnographic analysis. The value of this approach is considered by means of evaluating the development of a model to which the approach was applied.

Most of the problems for data management in today's wireless sensor networks were already dealt with during the past thirty years of the artificial neural-networks tradition and that kind of algorithms can be easily implemented to wireless sensor network platforms. These problems include the need for simple parallel distributed computation, possibility for distributed storage, fault-tolerance and in some cases the possibility of auto-classification of sensor readings. We will present dataacquisition through hierarchical two-level architecture with algorithms which will use wavelets for initial data-processing of the sensory inputs and neural-networks which use unsupervised learning for categorization of the sensory inputs. They are tested on a data obtained from a set of 4 motes, equipped with seven sensors each.

The aim of the present paper is to develop neuro-fuzzy models of the anaerobic organic digestion process in wastewater treatment from laboratory and simulated experiments accounting for the variable organic load, ambient influence and microorganisms state in MATLAB environment. The main contributions are determination of significant model parameters via graphical sensitivity analysis, simulation experimentation and design and study in MATLAB of two "black-box" models for the biogas production rate, based respectively on classical feedforward backpropagation and Sugeno fuzzy logic neural networks. The models can find application in process prediction, optimization and control.

Decision analysis and optimization are examples of inverse management problems which can be effectively handled by means of Artificial intelligence (AI) and simulation techniques. However, the application of these techniques in specific industrial contexts finds major constraints in the lack of formalized methodologies and systematic procedures to retrieve and handle the data required for their implementation, The paper proposes Knowledge Discover (KD) techniques as means means of data pre-processing for the development of AI-based decision support systems (DSSs). This use of Knowledge Discovery techniques is illustrated in relation to the design of a hybrid DSS - combining AI and simulation techniques - for the management of maintenance services in the public transport sector.

The software and hardware features of Interface and Reprogramming Controller (IRC) development are considered in this paper. IRC is the main part of Network Capable Application Processor (NCAP). The proposed IRC provides remotely, on-line reprogramming of NCAP. Also this IRC supports the set of wide used serial (RS232, RS485, SPI) and parallel (LPT ISA-8) interfaces. The main features of the proposed NCAP are the wide functionality in the condition of low price.
