Deep Convolutional Neural Network Based Object Detection Inference Acceleration Using FPGA
2022
Object detection is one of the most challenging yet essential computer vision research areas. It means labeling and localizing all known objects of interest on an input image using tightly fit rectangular bounding boxes around the objects. Object detection, having passed through several evolutions and progressions, nowadays relies on the successes of image classification networks based on deep convolutional neural networks. However, as the depth and complication of convolutional neural networks increased, detection speed reduced, and accuracy increased. Unfortunately, most computer vision applications, such as real-time object tracking on an embedded system, requires lightweight, fast and a…
A fog-assisted system to defend against Sybils in vehicular crowdsourcing
2022
Technological advancements in vehicular transportation systems have led to the growth of novel paradigms, in which vehicles and infrastructures collaborate to infer high-level knowledge about phenomena of interest. Vehicular Social Network (VSN) is one such paradigm in which vehicular network entities are considered as part of an Online Social Network (OSN), paving the way for new services derived from social context. Although vehicular crowdsourcing has tremendous benefits, its deployment in real systems requires to solve important challenges including defense against Sybil attacks. This paper proposes a novel fog-assisted system that uses SybilDriver to minimize the presence of Sybil enti…
Spectrum cartography techniques, challenges, opportunities, and applications: A survey
2021
The spectrum cartography finds applications in several areas such as cognitive radios, spectrum aware communications, machine-type communications, Internet of Things, connected vehicles, wireless sensor networks, and radio frequency management systems, etc. This paper presents a survey on state-of-the-art of spectrum cartography techniques for the construction of various radio environment maps (REMs). Following a brief overview on spectrum cartography, various techniques considered to construct the REMs such as channel gain map, power spectral density map, power map, spectrum map, power propagation map, radio frequency map, and interference map are reviewed. In this paper, we compare the pe…
Multi-objective optimisations for a superscalar architecture with selective value prediction
2012
This work extends an earlier manual design space ex ploration of our developed Selective Load Value Pre diction based superscalar architecture to the L2 unified cache. A fter that we perform an automatic design space expl oration using a special developed software tool by varying several architectural parameters. Our goal is to find optim al configurations in terms of CPI (Cycles per Instruction) and energy consumption. By varying 19 architectural parameter s, as we proposed, the design space is over 2.5 millions of billions configurations which obviously means that only heuristic search can be considered. Therefore, we propose dif ferent methods of automatic design space exploratio n based…

Estándar del inversor prudente y confianza legítima
2019
El trabajo analiza el conflicto planteado por las reformas del régimen retributivo de la electricidad renovable desde la perspectiva del principio de protección de la confianza del derecho de la Unión Europea. Se detiene en la jurisprudencia del Tribunal de Justicia sobre el alcance de dicho principio en el ámbito normativo; en especial, en el criterio del «operador económico prudente y diligente». El análisis identifica carencias en la jurisprudencia de los tribunales españoles («riesgo regulatorio»), como la errónea aplicación del estándar del inversor prudente, o la falta de ponderación del interés de la Unión.
De nuevo sobre la prevalencia del derecho estatal y la inaplicación judicial del derecho autonómico
2017
En varias sentencias recientes, el Tribunal Constitucional ha entendido por primera vez aplicable la clausula de prevalencia en caso de incompatibilidad sobrevenida norma basica-norma autonomica de desarrollo; ha negado dicha aplicacion cuando la incompatibilidad es originaria. Se plantea si tiene sentido esta distincion, y si la clausula de prevalencia deberia extenderse a los casos de choque entre titulos competenciales. La solucion que se apunta es afirmativa cuando el choque se produzca entre una norma basica en una materia y una norma autonomica dictada en otra materia distinta; aunque formalmente el titulo autonomico se califique como exclusivo.
Las declaraciones simbólicas de los municipios: entre la autonomía local, el postureo inocuo y el abuso
2020
El presente estudio aborda la legalidad de las declaraciones simbólicas municipales sobre cuestiones que no son propiamente de su competencia. En primer lugar, se presentan ejemplos de este tipo de declaraciones, y se aventuran algunas de las razones que las propician. En segundo lugar, se exponen y discuten los principales criterios utilizados por la jurisprudencia a fin de discernir cuándo una declaración simbólica resulta conforme con el ordenamiento jurídico y cuándo no. Finalmente, se ofrecen dos argumentos que invitan a embridar más decididamente la actividad declarativa de los municipios: la exigencia de neutralidad de la Administración, en relación con el principio de pluralismo y e…
