Abstract:

Software testing becomes more complex, more time-consuming, and more expensive. The risk that software errors remain undetected and cause critical failures increases. Consequently, in safety-critical development, testing software is standardized and it requires an engineer to show that tests fully exercise, or cover, the logic of the software. This method often requires a trained engineer to perform manual test generation, is prone to human error, and is expensive or impractical to use frequently in production. To overcome these issues, software testing needs to be performed earlier in the dev

The advent of services such as cloud computing, social networks and e-commerce has led to an increased demand for computer resources from data centers. Prominent issues for data center designers are sustainability, cost, and dependability, which are significantly affected by the redundant architectures required to support these services. Within this context, models are important tools for designers when attempting to quantify these issues before implementing the final architecture.

Abstract:

This work deals with the design of a 10-zones equalizer with optimized frequency characteristics with a spectrum audio analyzer. In this work the problem of processing audio signals using equalization for filtering the interference frequencies, correction of frequency cover signal boost or suppression of the required zones of the audible spectrum are also analyzed. The influence of subjective perception of sound intensity of the audio signals reproduction and its use in working with equalizer is discussed too. The work describes the principles and usage of the audio-analyzer as a tool for the

Abstract:

Le contrôle 3D de la lumière est réalisé, à l'échelle de la longueur d'onde, dans des circuits photoniques intégrés. La brique élémentaire choisie dans cette étude est le cristal photonique (CP) membranaire qui, par ses propriétés de dispersion, permet un contrôle de la lumière à la fois dans le plan (optique guidée) et hors du plan (dispositifs adressables par la surface). En particulier, l'exploitation de modes de Bloch situés au point Gamma de la courbe de dispersion (k//=0) permet l'émission de la lumière dans la direction verticale. Dans cette étude, nous nous sommes focalisés sur des cri

Abstract:

Marine renewable energy promises to provide a significant contribution to the future electricity supply. It is estimated that 17% of today's UK electricity demand could be generated from wave and tidal sources. The ambition to harvest this resource is in the public interest, as it eases the pressures on energy security, holds the potential to reduce carbon emissions and has the prospect to create a new UK industry sector worth £15 billion. From an engineering perspective, marine energy is one of the least developed renewable energy technologies and has to be regarded as unproven. The reliabili

Abstract:

Hlavným cieľom tejto práce je vytvorenie simulácií rôznych algoritmov riadenia asynchrónneho motora a vzájomné porovnanie ich vlastností. Zaoberá sa taktiež možnosťami konfigurácie náhradného zapojenia na T-článok, -článok a -článok. Obsahuje jednak teoretický rozbor, a taktiež aj simulácie jednotlivých spôsobov riadenia spolu s podrobným návodom na ich realizáciu. Celkovo budú vykonané 3 simulácie – simulácia vektorového riadenia s orientáciou na rotorový tok, vektorového riadenia s orientáciou na statorový tok a simulácia takzvaného prirodzeného riadenia.

Abstract:

The number of wireless devices has grown tremendously over the last decade. Great technology improvements and novel transceiver architectures and circuits have enabled an astonishingly expanding set of radio-frequency applications. CMOS technology played a key role in enabling a large-scale diffusion of wireless devices due to its unique advantages in cost and integration. Novel digital-intensive transceivers have taken full advantage of CMOS technology scaling predicted by Moore's law. Die-shrinking has enabled ubiquitous diffusion of low-cost, small form factor and low power wireless devi
