1. Omni-Directional Wideband Antenna Array with Solar Cells
Abstract Distributed sensor networks are becoming more and more widespread due to their substantial benefits to our daily lives. These sensors, in most cases, are distributed in nature and even may require mobility. This, in turn, implies omnidirectional collector units to collect the data from various sensors at arbitrary directions. This work summarizes th

3. Co-Design of a GPS Antenna Low-Noise Amplifier Front-End Circuit
Abstract This paper presents a clear and fast design procedure for directly matched low noise active integrated microstrip antenna front end circuits. Initially, a theoretical analysis is given for the overall gain equivalence between traditional and directly matched antennas. Then, a detailed procedure is presented for the design and construction of a fully

7. Una lectura neoconstitucional de la teoría del poder de policía
Abstract The power of administrative policy is a very polemical issue in the Administrative Law area. It refers not only to the way of the Public Administration should act in front of the people, but also reflects an ideological position adopted by the State in the exercise of its authority. Furthermore, his proximity with other problematic issues, for insta

10. A high-level dynamic analysis approach for studying global process plant availability and production time in the early stages of mining projects
Abstract In the early stage of front-end studies of a Mining Project, the global availability (i.e. number of hours a plant is available for production) and production (number of hours a plant is actually operated with material) time of the process plant are normally assumed based on the experience of the study team. Understanding and defining the availabili
