A dual energy radiography method using basis decomposition was developed, the process to do it is shown and it is compared against an alternate more direct method of analyzing the data using the logarithm of the original data, concluding that this second method does work but it is not better than basis decomposition.

The purpose of this study is to perform an analysis on a discussion of REST creator Roy Thomas Fielding, where he exposes a critique of implementations that claim to use the architectural model proposed in his thesis. Implementations of APIs that manifest themselves as RESTFUL are used as object of study. Architectural Constraints are used which refer to important features of the model to verify these implementations, where they must succeed in these comparisons with the constraints, so that they can prove to implement the model. The conclusion is that there are in fact several implementations that are improperly named, where they have several similarities to the model in their implementation, but do not agree with the constraints that must be implemented so that it can be considered an instance of the model.

En este documento se explican qué son las matrices, los distintos tipos que hay, algunas operaciones que se hacen con ellas con ellas (y sus respectivas propiedades), además de enseñar cómo realizar estas operaciones en programación. Incluye el concepto de relación binaria, y se explica cómo se pueden representar éstas (si son homogéneas) mediante grafos. y los distintos tipos de éstos últimos. Se recalca la "matriz jacobiana", explicando su función escalar y vectorial

This research paper aims at exploiting efficient ways of implementing the N-Body problem. The N-Body problem, in the field of physics, predicts the movements and planets and their gravitational interactions. In this paper, the efficient execution of heavy computational work through usage of different cores in CPU and GPU is looked into; achieved by integrating the OpenMP parallelization API and the Nvidia CUDA into the code. The paper also aims at performance analysis of various algorithms used to solve the same problem. This research not only aids as an alternative to complex simulations but also for bigger data that requires work distribution and computationally expensive procedures.

Ce livret retrace l'histoire de la lutte contre le projet de l'aéroport international du Grand Ouest, à Notre-Dame-Des-Landes à une vingtaine de kilomètres au nord de Nantes, en apportant des arguments pour expliquer les raisons d'être et les motivations du mouvement de la résistance. Il est rédigé à l'origine pour accompagner le jeu de plateau coopératif "Zone à Défendre" .
