Nuevos materiales para el hotel del futuro

Sacyr participa y lidera el subproyecto 2, consistente en la edificación del hotel del futuro, dentro del proyecto THOFU 'Tecnologías del Hotel del Futuro'. Se trata de un proyecto del programa CENIT del Ministerio de Economía y Competitividad, orientado a la investigación planificada y la creación de productos, procesos o servicios que integren diferentes tecnologías de interés estratégico

Definición del modelo de negocio y plan de marketing de un hotel de Madrid

El objetivo de este proyecto es el desarrollar el plan de negocio para analizar la viabilidad de un hotel situado en el centro de Madrid. El Plan de negocio pretende lograr un conocimiento objetivo sobre la idea del proyecto que se quiere poner en marcha, a la vez que sirve como base para conseguir recursos y capacidades necesarios para implementar el plan y obtener la financiación. ABSTRACT The aim of this project is to develop a business plan to analyze the feasibility of an hotel located in the city center of Madrid. The Business Plan aims to achieve an objetive knowledge about the project idea which intends to set in motion, at the same time serving as a basis to get resources and the necessary capabilities to implement the plan and obtain the financing.

Optimization methods for the operating room management under uncertainty: stochastic programming vs. decomposition approach

The operating theatres are the engine of the hospitals; proper management of the operating rooms and its staff represents a great challenge for managers and its results impact directly in the budget of the hospital. This work presents a MILP model for the efficient schedule of multiple surgeries in Operating Rooms (ORs) during a working day. This model considers multiple surgeons and ORs and different types of surgeries. Stochastic strategies are also implemented for taking into account the uncertain in surgery durations (pre-incision, incision, post-incision times). In addition, a heuristic-based methods and a MILP decomposition approach is proposed for solving large-scale ORs scheduling problems in computational efficient way. All these computer-aided strategies has been implemented in AIMMS, as an advanced modeling and optimization software, developing a user friendly solution tool for the operating room management under uncertainty.

Demonstration of the operation principles of intermediate band solar cells at room temperature

In this work we report, for the first time at room temperature, experimental results that prove, simultaneously in the same device, the two main physical principles involved in the operation of intermediate band solar cells: (1) the production of sub-bandgap photocurrent by two optical transitions through the intermediate band; (2) the generation of an output voltage which is not limited by the photon energy absorption threshold. These principles, which had always required cryogenic temperatures to be evidenced all together, are now demonstrated at room temperature on an intermediate band solar cell based on InAs quantum dots with Al0.3Ga0.7As barriers.
