Renewable energy is often suggested as a possible solution for reducing greenhouse gas emissions and decreasing dependency on fossil energy sources. The most readily available renewable energy sources in Europe, wind, solar and biomass are dispersed by nature, making them ideally suited for use within …

The European Union is striving for a high penetration of renewable energy production in the future energy grid. Currently, the EU energy directive is aiming for 20% renewable energy production in the year 2020. In future plans the EU strives for approximately 80% renewable energy production by the year …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

The issue of management of the supply chains of electronics in a sustainable manner is becoming more and more important all around the world. There are growing concerns about the amounts of electronic waste, controversial labour practices and the chemical and energy consumption management. These are …

The objective of an energy management strategy for fuel cell hybrid propulsion systems is to minimize the fuel needed to provide the required power demand. This minimization is defined as an optimization problem. Methods such as dynamic programming numerically solve this optimization problem. Strategies …

SBM Schiedam is active in the design, engineering and construction of Floating Production Storage and O oading (FPSO) ships. Currently SBM has a few projects for Petrobras. Purpose of an FPSO is to produce oil from a subsea oil eld. The FPSO production process is split over di erent modules which can …

Fuel cell hybrid power trains comprise an energy storage to supply peaks in the power demand and to facilitate regenerative braking. In terms of control systems, the presence of storage provides additional freedom to minimize the vehicle’s fuel consumption. In a previous paper [1] an analytical solution …

INTRODUCTION: It is difficult to adjust fluid balance adequately in patients with severe burns due to various physical changes. B-type natriuretic peptide (BNP) is emerging as a potential marker of hydration state. Proteinuria is used as a predictor of outcome in severe illness and might correlate to …

from the article: The demand for a wireless CO2 solution is ever increasing. One of the biggest problems with the majority of commercial available CO2 sensors is the high energy consumption which makes them unsuitable for battery operation. Possible candidates for CO2 sensing …

Tomato (Lycopersicon esculentum) is one of the important vegetables in Rwandese diet, since it is rich in health valued food components such as carotenoids (Lycopene), ascorbic acid (Vitamin C), vitamin E, folate and dietary fibers. The post harvest loss in tomatoes has been estimated to be about 20-30% …
