this document presents the new model of distributed consumers of electricity powering - named Power Modes. there is presented a conceptual model of an IT hierarchical distributed system for dataacquisition and evidence the state of the controlled distributed object - the electric energy consumption. the authors will try to show that the proposed model of the IT system is accurate to solve the problem of the electric energy consumption management. In this context the proposed solutions are written into the DSM methods of power system balancing [1]. the competency of the paper is the presentation of the prototype system of intelligent metering which is developed and claimed for a patent protection [2, 3].

this study examines cross-functional teams and their impact in line with operational performance and system effectiveness after the implementation of intelligent information and retrieval systems in organisations. Multiple regression analysis was used to determine the structural relationships and look for the phenomenon of cross-functional teams, operational effectiveness, and system effectiveness in the betterment of operational performance. Preliminary findings suggest that the quality and speed from operational effectiveness and the quality of information and quality of the services from systems effectiveness are the two key factors for cross-functional teams to enhance operational performance.

In classification systems like eCl@ss[1] the number of classes grows and products like for example, screws are spread across several segments related to selected applications or industries. Entropy functions on test sets are used to calculate the dispersion of products across the classification system. For such dispersed classes the corresponding property sets are compared and it is shown that there is a real need for the harmonisation of property sets to improve e-commerce applications.

the design and realization of an automated acquisition setup, dedicated to experimental evaluation of intermittent chaotic phenomena and the related statistics, is presented. the setup was implemented in National Instrument's LabView environment and it was structured in such a way that it is not dependent of the signal-registering devices used. the circuit evaluation is achieved by registering only one signal. An experimental intermittency example confirms the system's effectiveness.

Large-scale, data-intensive computing requires a sophisticated technology to be integrated with distributed file systems to provide clients with reliable and scalable high-performance accesses to the stored data. the clients physically share storage devices connected via a network like GigaEthernet or Fibre Channel and, on those clients, distributed file systems take responsibility for providing coordinated accesses and consistent views of shared data. In such a distributed computing environment, one of the major issues in achieving substantial I/O performance and scalability is to build an efficient locking protocol. In this paper, we present a distributed locking protocol that enables multiple nodes to simultaneously write their data to distinct data portions of a file, while providing the consistent view of client cached data. We conclude with an evaluation of the performance of our locking protocol.

the purpose of this article is to describe the research that was made to investigate approximation of human maxillary dental arch curvature by different mathematical curves. the main goal of this work is to select mathematical functions that most precisely approximate the maxillary arch contours of the upper occlusion. In this study 8 dental casts were analyzed. To perform this work the polynomial, Parabolic, Catenary, Beta curves, optimized by Least Squares Method, were used.

this paper presents a software package developed for the simulation of spatial mechanisms with both rigid and flexible links. In order to formulate the equations of motion of the system joint coordinates and homogenous transformation are used. Flexible links are discretised by means of the Rigid Finite Element Method (RFEM). In the paper the implementation of the package in C++ is presented. Some results of indirect verification of the software package for sample mechanisms are presented.

An intelligent multichannel dataacquisition (DAQ) system based on the novel integrated circuit of Universal Sensors and Transducers Interface (USTI) or USTI-1M-20 with high metrological performances is described in the paper. It can be used with any existing quasi-digital as well as analog sensors and transducers. A parallelism in such systems was realized as time-division channeling and combined channeling, included both: the time- and space- division channeling. the new modified method of the dependent count for frequency (period) measurements lets introduce adaptive features in such DAQ systems. In addition to the self-adaptation capability the sensors in such systems will have self-identification capability due to the TEDS according to the ieee 1451 standard in the ICs' memory. the described design approach can be used also for creation low cost, high performances multichannel, multifunctional DAQ systems for basic environmental sensing parameters as well as many other custom sensing applications.

Software architecture for dynamic balancing of calculations in heterogeneous computing clusters has been proposed. Existing systems for automatic and semiautomatic parallelizing are analyzed. Software was implemented on C++ and used for parallelizing algorithms with different dependencies on data between processors. Comparison of DDCI (Dynamic Distribution Calculations Interface) to MPI is given. Conclusions about DDCI advantages and future work directions are made.

this paper introduces a hierarchical design model for embedded systems which includes models of the application, the embedded system and the resources. the application model deals with locations to better describe distributed architectures. A location-driven method for design of distributed embedded systems is proposed as a direct extension of the design model. the method allows to benefit from fuzzy relationships between I/O variables and locations. An example shows a 29% reduction of the hardware complexity measured in number of pins. the paper introduces a dynamic computational model and a software tool named CASTLE. the tool automatically inserts power management code for small systems.
