In this paper chaos identification and determination of values of parameters that correspond to chaotic behaviour in erbium-doped fiber ring laser is considered. Method based on the time-frequency representation of signals is used for determination of chaotic boundaries in one and two-parameter space. Obtained results agree well with those that can be found in literature.

Improvements of both software and hardware in area of digital television enables interaction between content provider and content consumer. Consumers get the choice of selecting desired content. This evolved to a requirement of an additional screen and content protection. In this paper DTCP-IP protection is proposed, enabling safe transmission of content.

In previous work we have analyzed the scalability and quality of approximation of modified CLEAN algorithm applied in geophysical 3D gravity inversion in parallel systems. In this paper we focus on detailed presentation of error calculation applied for the inversion, necessary for realistic solution of multimodal inversion cases. At the end, a comparison of error results from different used formulas is presented

As a result of dense installations of public mobile base station, additional electromagnetic radiation occurs in the living environment. Research group of accredited Radio-communications Laboratory, has been involved in human exposure assessments of GSM/UMTS base stations for over 15 years. Within these activities over 2200 base station locations (indoor, masts and locations with installations on buildings) of 5 GSM/UMTS mobile operators in Serbia and in Montenegro were analysed, by simulation and/or measurements. The results of extensive electromagnetic field strength measurements will be presented. Further, it was shown that the measurement process can be significantly accelerated by using shorter time intervals of averaging, while not compromising too much on measurement quality.

A semi-Markov process, as a model of interpretation of an algorithm by embedded controller is considered. Generation of transactions in digital controllers as a result of random wandering on states of semi-Markov process is described. Mathematical expressions for evaluation of stochastic characteristics and time lag densities between transactions are obtained. Latencies between transactions is considered as an important parameter for proper synthesis of control algorithms in real-time embedded digital control systems.

A new algorithm of pre-combination of real image and the image synthesized according to digital terrain map is offered. It has high performance in comparison with correlation-extreme methods. The algorithm allows to localize the point with real coordinates of aircraft in the space of six navigation parameters.

Digital signal processor (DSP) evolution trends now to multicore architectures. Parallelization of signal processing algorithm becomes one of the most important challenge while migrating from single to multi-core. Specifically, a problem of such a classical DSP algorithm as finite impulse response (FIR) filtering implementation on multicore DSP is of great interest. Parallel form of FIR filter for implementation on multicore DSP is considered in this paper. TMS320C6678 DSP from Texas Instruments is used. It is shown that parallel FIR form has some advantages over direct FIR form when implementing on multicore processor. Experimental results of the offered approach implementation with OpenMP parallel programming technique are demonstrated.

Based on the Earliest Deadline First policy guaranteeing timeliness for hard real-time systems, we propose an enhanced EDF algorithm that varies distinct processor modes with time. Processor modes are determined by supply voltage, frequency and performance requirements, allowing for discrete control of the processors' energy consumption. Thus, processors using the enhanced policy will dissipate less energy and, at the same time, adhere to the deadlines of hard real-time systems.

Many of the largest information technology industry leaders today have turned their attention to Wireless Health with wireless services, new personal hardware products, search technologies that focus on health and wellness with data and guidance. The impact on individuals is also unprecedented with individualized, lifetime, health promotion, services that join consumer fitness and entertainment, disease management, and a major advance in geriatric care with individualized guidance and monitoring for individuals in their homes and institutions. Research in wireless health is radically different from research in other areas of Computer Science and Engineering. In this talk we will review key ingredients of a successful research paradigm in Wireless Health. We use Remote Health Monitoring Systems as a case study. Requirements and Objectives of the underling embedded system, along with the corresponding clinical process, will be discussed.

This paper presents a sinusoidal Wien-bridge ring and relaxation wide range voltage controlled oscillators. All described oscillators have potential using in different application, e.g. phase locked loops, modulation and detection. The frequency changing is based on optically coupled resistor with 100 dB dynamic range. The oscillators were constructed and measured.
