Polarimetric SAR interferometry has been recently applied with TanDEM-X data to the retrieval of vegetation height in rice fields, which constitutes the first demonstration of this technique applied to agricultural crops with satellite data [1]. In this work we extend that study by including an analysis of the effect of incidence angle and baseline on the retrieval of height. The study is based on...
Polymer electrolyte membrane fuel cells (PEMFCs) have the potential to play a major role as energy sources for transportation and portable applications because they feature high power density at relatively low operating temperatures. Bipolar plates are a key component of PEMFCs in terms of cost and weight. To date, many different materials for bipolar plates have been investigated and an alternative...
M-Learning is an exciting art of using mobile technologies to enhance learning skills. Mobile phones, PDAs, Pocket PCs and the Internet can be joined together in order to engage and motivate learners, anytime anywhere. The society is entering a new era of m-Learning, which makes important to analyze and innovate the current educational tools. In addition Learner-Centered Design (LCD) is considered...
A constructive heuristic algorithm (CHA) to solve distribution system planning (DSP) problem is presented. The DSP is a very complex mixed binary nonlinear programming problem. A CHA is aimed at obtaining an excellent quality solution for the DSP problem. However, a local improvement phase and a branching technique were implemented in the CHA to improve its solution. In each step of the CHA, a sensitivity...
This paper presents a 5-years experience in a Knowledge Management Program in an energy sector company, characterized by geographical dispersion, different languages and cultures, standard processes, decentralized organization and high impact of technical knowledge. The approach is based on communities of practice (CoP). During this period a team has worked to facilitate and promote the exchange of...
