Selective catalytic reduction (SCR) was used to reduce exhaust gas nitrogen oxides (NOx) from the emissions of a 710kW combined heat and power system fueled by dairy biogas. Exhaust gas NOx was reduced from 63.1±31.9 to 14.2±17.5ppmvd@15% O2 such that emissions were 0.33±0.40gkW−1h−1,...

Business processes design optimization is known as the problem of creating feasible business processes while optimizing their criteria such as resource cost and execution time. In this paper, the authors propose an evolutionary multi-criteria approach based on a modified evolutionary algorithm...

The dimension synthesis problem for parallel robots in general is much more complex than their serial counterparts, due to the strong dependence of geometric parameters and their performances. In dimension synthesis for robots, typical performance characteristics that may be considered to...

The aim of this paper is to analyze the mutual interdependencies and trade-offs between heat storage and district heating network considering economic and ecological aspects. Therefore, a MILP (mixed integer linear programming) problem of a distributed energy system is formulated with a weighted...

Renewable energy can help developing countries meet their sustainable development goals through access to clean, secure, reliable and affordable energy. The scarcity and the depletion of conventional energy resources, with rising fuel prices and harmful emissions from fossil fuels, make...

A thermoelectric (TE) cooler architecture is presented that employs thin film thermoelectric elements on a plastic substrate in a corrugated structure sandwiched between planar thermal interface plates. This design represents a hybrid of a conventional bulk TE device and an in-plane thin film TE...

This paper proposes the use of a Function Deployment Model (FDM) for continuous and discontinuous innovation product development. To demonstrate its usefulness in a real situation, the model was applied to the design problem of a multi-function sampling instrument used in the ESA (European Space...
