Comparative Analysis of Different Renewable Fuels for Potential Utilization in SOFCs

Fuel cells are promising due to advantages with higher energy conversion efficiency and lower emissions of SOX, NOX and CO2 than conventional power systems. Solid oxide fuel cell (SOFC) is a high temperature fuel cell, which operates at 600-1000 ºC. The high operating temperature and the anode material allow SOFCs to operate with different types of fuels from both fossil and renewable sources due

Pictures as language

The purpose of this lecture is to shed light on a potential, and invite those who are interested to join in and make use of this potential. Here is the background: Starting with the Isaac Project in 1993, Certec has developed a technological/educational concept based on pictures as language for people with limited spoken language or none at all. There are a number of case studies (our own and ot

UML and SystemC - Comparison and Mapping Rules for Automatic Code Generation

Today embedded system development is a complex task. To aid the engineers new methodologies and languages are emerging. During the development the system is modelled using different tools and languages. Transformations between the models are traditionally done manually. We investigate the automation of this process, specifically we are looking at automatic UML to SystemC transformation. In this pa

Design of Energy Saving Windows with High Transmission at 900 MHz and 1800 MHz

This paper focuses on the radio wave propagation through energy saving windows. These panes have a metallic shielding that keeps the heat inside the building during winter and outside during summer. Unfortunately, this covering also has an opaque behaviour at microwave frequencies. A design of energy saving window panes with high transmission at 900MHz and 1800MHz is presented. The high transmissi

The human diving response - effects of temperature and training

The aim was to elucidate the cardiovascular response associated with breath-hold diving, especially the effects of temperature in its elicitation and the effects of different types of training on the human diving response (DR) and breath-holding time (BHT), and to evaluate the human DR in a mammalian perspective. A model for simulated diving by apnea and facial immersion in cold water was develope
