Technological advances have allowed to collect and store large volumes of data over the years. Besides, it is significant that today's applications have high performance and can analyze these large datasets effectively. Today, it remains a challenge for data mining to make its algorithms and applications equally efficient in the need of increasing data size and dimensionality [1]. To achieve this goal, many applications rely on parallelism, because it is an area that allows the reduction of cost depending on the execution time of the algorithms because it takes advantage of the characteristics of current computer architectures to run several processes concurrently [2]. This paper proposes a parallel version of the FuzzyPred algorithm based on the amount of data that can be processed within each of the processing threads, synchronously and independently.

Parallel parking, in general, is a moderate difficulty maneuver. Moreover, for inexperienced drivers, it can be a stressful situation that can lead to errors such as stay far from the sidewalk or damage another vehicle resulting in traffic tickets that range from simple parking violation to crash-related violations. In this work, we propose a computationally effective approach to perform a collisionfree parallel parking. The method will calculate the minimum parking space needed and then the efficient path for the parallel parking. This method is computationally inexpensive in comparison with the current state of the art. Moreover, it could be used by any car because the parameters needed to perform all computations are taken from the specifications of real cars. Preliminary results of this work were summarized in [1] that was presented at the 15th International IEEE Conference on Intell...

Compañías mineras están en búsqueda constante de nuevas tecnologías para aumentar su productividad. Una de las tecnologías que les permite realizar la reconstrucción de la superficie sin poner en riesgo la vida de sus trabajadores es el uso de sensores LiDAR junto con plataformas móviles que les permiten rotar el sensor para realizar un escaneo completo de la estructura. Sin embargo, el procesamiento de los datos se realiza a través de ordenadores situados fuera de la mina, debido a su alto coste computacional, lo que se traduce en un alto coste de tiempo. En esta tesis presento como objetivo principal el diseño de un algoritmo paralelo para la fusión de nubes de puntos capturadas por un LiDAR y la reconstrucción de la superficie en tiempo real, con el fin de reducir el tiempo de procesado, teniendo en cuenta información a priori del patrón de barrido de los puntos. En la l...

Swarm robotics focuses on the study and development of robot systems containing a large number of agents that interact with each other in a collective behaviour in order to achieve tasks or overcome obstacles. Bristlebots are vibration-driven mobile robots. They are characterized by small size, high speed, simple design and low costs for production and application – qualities which are advantageous for agents of swarm robotic systems. However, most studies have been developed over systems with no control or systems with two or more actuators. The aim of this master thesis is the development of a bristle based robot agent for a swarm robotics microsystem with units for locomotion, sensing, data processing, control, communication and energy storage. New approaches in modelling and development of swarm agents are given, and a robot prototype is presented. The robot is driven by a single D...

The image analysis is a subject on which much emphasis is being given with purpose of identifying parameters, data, visual features in the image that provide us information about environment, it is represented in the image, but without the intervention of a person. Many methods have been developed with passing of the years, each seeking to minimize the error. The vast majority of implementations of these Facial Recognition Systems have been in a computer and a few have been implemented on hardware. This paper presents a Face Recognition System based on FPGA, The FPGA is configured with the language VHDL, this system is independent of a computer, this will give the system based on FPGA three main advantages, which include fast processing thanks to the ability of the FPGA that can perform parallel processes, and the other two advantages are the size and weight that are important to have mo...

Agile approaches consider the software architecture as an emergent feature that can have an intended structure but could be not documented. To controlling the architectural erosion, an architectural conformance analysis could be performed, but considering the source code as a primordial input. This work presents a framework that supports the development of applications for architectural conformance analysis based on rules and measures. The framework uses aggregated graphs, MapReduce operations, and an external DSL; and has been evaluated over studies related to software architecture, and projects like the test suite of Red Hat WildFly and WordPress for Android. The gotten results favor the use of the framework for executing a continuous architectural analysis from source code.
