The paper presents an MPEG−7 Multimedia Description Schemes (MDS)−based metadata and user profile model used within an enhanced DTV environment for semantic annotation and personalized access to multiple sports DTV services. It is shown that in order to enable intelligent and personalized processing, management and use of multimedia content and services, the use of application specific metadata...

We have designed an original approach for efficient Second Harmonic Generation of tailored V-shape benzo[b]thiophene molecular systems enabling versatile and flexible one-step, dry and technologically friendly thin film processing. The designed moieties show chi((2)) values at least as high as the reference LiNbO(3) single crystal, without poling processing and matching the constrains of integr...

An H.263 video encoder implementation without negotiable coding options on BOPS Manta DSP is presented. First, the ManArray architecture is described. Then, partitioning between the multiple processing elements (PEs) and implementation issues of the video encoder are discussed. Based on the results of this experiment, we discuss the suitability of this parallel implementation platform for video...

An optimum electronic intelligence system configuration incorporating the state of the art technologies and achieving the highest parameter accuracies while processing the complex intrapulse modulated radar signals is presented in this paper. The system is based on the quad digital receiver, a state of the art single board solution for the detection and analysis of modern radar signals. The sys...

This paper presents our work on a demonstration platform for a software defined radio proof-of-concept. The aim of the demonstrator is to show seamless switching between different functions of an IEEE 802.11a [1] WLAN OFDM system on an adaptive execution environment. The mechanisms and interfaces for dynamic, reliable and secure Software Defined Radio (SDR) equipment reconfiguration are investi...

Elasticity describes the ability of any distributed system to scale to a varying number of hosts in response to workload changes. It has become a mandatory architectural property for state of the art cloud-based data stream processing systems, as it allows treatment of unexpected load peaks and cost-efficient execution at the same time. Although such systems scale automatically, the user still ...

In the present investigation, dissimilar friction welding between AA6063-T6 and SS 304L materials of pipe joint configuration with an outer diameter 88.90 mm a wall thickness 5.4 was performed. Four different experimental conditions were varied based on visual inspection after each weld. The welded joints evaluated by vacuum leak detection, thermal shock test, pneumatic pressure tensile optical...

Our work concerns the use of cloud computing for data processing. To study the problem, we designed a framework for experimenting with various cloud-computing arrangements. The main goal is a framework that has the ability to automatically track the configuration, providing event management, performance measurement and testing for small-scale cloud computing. We show how such a framework can be...
