This article presents a complete analytical description of the rotor broken bars effects on the induction machine behavior, for diagnosis purposes. The stator current and the electromagnetic torque are important elements to study in order to define the behavior of the healthy induction machine and can provide a model-based approach of the rotor bars fault detection in induction machine. An experimental validation of the proposed analytical approach is provided.

We present an approach to compression of segmented images using wavelet transform followed by modified baseline coder. Baseline coder processes the spectral values from all segments in non-segmented style, i.e. together in one big block. Proposed scheme has comparative results as existing methods and retains its effectivity as the number of image segments increases.

All the abstraction levels of VHDL-AMS, properly used, would allow designing a whole system without using physical prototype. The virtual prototyping could replace physical prototyping, only the last prototype has to be fabricated. Work has to be done by using description modelling and predictive modelling of objects under study and by using modelling of the environment in which the system runs. Technological choices, dimensions, operating modes will be studied and compared. An example of parallel optical module will be taken for illustrating this purpose. The assembly within a single optoelectronic interconnect module of different components, including VCSEL and photodiode arrays, optical fibers and electronics implying electrical, optical, mechanical and thermal interactions, introduces new constraints in the conception phase and necessitates a new and different approach for modeling and simulation. A promising solution, when conceiving optoelectronic MOEMS is obtained by simulation with the multilevel language VHDL-AMS based on system component parameters and standards.

The investigation how to optimize the LonTalk/EIA-709.1 media access protocol in terms of the soft real-time requirements is presented. As a criterion of usage of the LonWorks networks under soft real-time requirements we assume that either the probability of collision, or the jitter of the access delay must be bounded and small enough. The arguments for selection of the unacknowledged service as the most suitable for real-time services are put forward. The simulation results of the collision rate and the mean access delay as a function of the offered load are presented. The delay jitter for light traffic load is evaluated. Two analytical models for the probability of packet collision are suggested. The one is based on the classical approach and used for light traffic conditions. The other is employed for steady-state heavy load. The conclusions present recommendations for designing soft real-time applications using LonTalk/EIA-709.1 channel.

The design of real-time embedded systems is a challenging field of research. Those systems use generally very small processing nodes that are interconnected and linked to sensors using an heterogeneous communication system. One primary aspect of our work, focuses on providing a suitable communication platform for real-time applications in an heterogeneous environment. We have developed a new real-time scalable middleware OSA+. The original concepts used in designing OSA+ is especially suited for embedded systems constrained by a small memory footprint requirement. This paper presents these concepts and current results of OSA+.

This paper presents a model of an optical transmitter module (driver & laser) which takes into account temperature, besides electrical and optical effects. MOSFET is an important component of the driver, temperature occurs in its different parameters such as carrier mobility. The vertical cavity surface emitting laser (VCSEL) is managed by equations of continuity which describe optical and electrical behaviour. The VCSEL parameters depend also on temperature. This is why a thermal model has been added for showing the thermal exchange between VCSEL and other connecting components. VHDL-AMS language allows to describe these different multi-technological phenomena: electrical, optical and thermal.

The work is intended to explain basic ideas related to the problem of design of control system for precise motion flex electromechanical system. The higher complexity of the system owing from nonlinearly (dry friction, backlash) and variable limitations defines using of a number of the simplifying assumptions. The control system design is made in the time domain and based on modal discrete-time control. Computer simulation is important by check of controlled system works in various modes. Three-mass two drive flex mechanics system has been developed and tested.

In the discrete event system such as a flexible manufacturing system, many kinds of work exist together in one system. Each processing is done by the shared resource. The flow of each work mutually becomes an intertwining net structure. The shared resource will be occupied when congestion occurs by the flow of a certain work, it influences the flow of other work, it generates new congestion, and it spreads to the entire system. As a result, it falls into the situation where processing stagnates in the entire system. Therefore, controlling so as not to cause congestion in the flow of each work is indispensable. However, because it differs from single flow, and the bottleneck of the flow of each work changes by the ability distribution to each work in the shared resource, it becomes very complex. Then, the authors propose the approach for achieving the entire flow analysis for the discrete event system with the net structure and the shared resource intersection, by deriving the relational expression of I/O of which the parameter is the ability distribution of one shared resource to each flow, and connecting this one by one. And, the application to the control that improves the performance of the system is examined.
