The energy and exergy flow for a space heating systems of a typical residential building of natural ventilation system with different heat generation plants have been modeled and compared. The aim of this comparison is to demonstrate which system leads to an efficient conversion and supply of...

Exergy analysis is a more powerful tool than mere energy analysis for showing the improvement potential of energy systems. Direct use of solar radiation instead of degrading other high quality energy resources found in nature is advantageous. Yet, due to physical inconsistencies present in the...

Purpose – The non‐destructive inspection of large concrete walls (e.g. dams, bridge pylons) with autonomous systems is still an unsolved problem. One of the main difficulties is to develop a very flexible platform, which is able to move and inspect horizontal and vertical surfaces safely,...
