Fuel cells are clean generators that provide both electrical and thermal energy with a high global efficiency level. The characteristics of these devices depend on numerous parameters such as: temperature, fuel and oxidizer pressures, fuel and oxidizer flows, etc. Therefore, their influence...

This paper proposes a novel, model-based control strategy for absorption cooling systems. First, a small-scale absorption chiller was modelled using artificial neural networks (ANNs). This model takes into account inlet and outlet temperatures as well as the flow rates of the external water...

Complexity of implementing construction projects has attracted various approaches in meeting project objectives. Among viable approaches, the purpose of this study considers mediating role of public procurement regulatory framework in successful construction project implementation. A dynamic...

Plug-in electric vehicles (PEV) are emerging as an efficient and sustainable alternative for private and public road transportation. From the point of view of electric grids, PEVs are currently considered as simple loads due to their low market penetration. However, as the PEV fleet grows,...

The current situation of the offshore wind market is characterized, among other things, by two opposing forces. On the one hand, there are a few already tested solutions that can be considered almost industrialized under certain conditions of sea bed depth and distance from shore, and investors...

At present, much interest is being shown in absorption refrigeration cycles driven by low temperature heat sources, such as solar energy or low-grade waste-heat. Double-lift absorption cycles working with ammonia-water have been recommended for refrigeration applications which require cold at...
