Analysis of Topological Impact on Wireless Channel Performance on Intelligent Street Lighting System

In this work, an analysis of the physical radio channel propagation for the deployment of a wireless sensor network for intelligent street lighting is presented based on an in house implemented 3D ray launching code. Simulation as well as measurement results from a deployed wireless sensor network for an intelligent street light control system confirm the topological and morphological dependence of the considered scenario. The results can be applied to the optimal radioplanning of the wireless systems prior to deployment phase, in order to achieve maximum system performance while minimizing power consumption

Desarrollo de un nuevo SMC sostenible con una resina termoplástica

Ejemplar dedicado a: Composites, jec 2023 y equiplast 2023El SMC (sheet molding compound) es un material compuesto comúnmente usado para fabricar piezas por un proceso de moldeo por compresión en caliente. Este compuesto cuenta con dos características claves para el sector de la automoción: permite producir piezas con una elevada cadencia y presenta una gran flexibilidad para el diseño de piezas de diversas formas y tamaños. Su gran inconveniente, como el de los materiales compuestos, en general, es que no se pueden reciclar y al final de su vida útil terminan almacenados en vertederos. En este trabajo, presentamos un nuevo SMC sostenible fácilmente reciclable mediante el uso de una resina termoplástica líquida patentada en el CSICSMC (sheet moulding compound) is a composite material commonly used to manufacture parts by a hot compression moulding process. This composite has two key characteristics for the automotive sector: it allows parts to be produced at a high rate of production and it has great flexibility for the design of parts of various shapes and sizes. However, like other composite materials, its primary drawback lies in the limited recyclability, resulting in their disposal in landfills at the end of their lifespan. In this work, we present a new and sustainable SMC using a liquid thermoplastic resin patented at CSICLos autores agradecen al MICINN proyecto PDC2021-120853-I00 y al CDTI proyecto PTAS20211010 por la financiación recibid
