Micro combined heating and power (micro-CHP) systems are becoming more than important, and even essential, if we pretend to take full advantage of available energy. The efficiency of this kind of systems reaches 90% and important savings in energy transport processes can occur. In this research, an internal combustion engine (ICE)-based micro-CHP system was developed and tested under specific c...

This paper examines the nature of first mover advantages on spatiallydifferentiated surface transportation networks. The literature on first mover advantages identifies a number of sources that explain their existence. However whether those sources exist on spatial networks, and how they play out with true capital immobility have been unanswered questions. By examining empirical examples includ...

(1) Background: Why and when images of watching eyes encourage prosocial behavior is still subject to discussion, and two recent meta-analyses show no effect of watching eyes on generosity. This study aims to discern the effect of watching eyes of different valence on two separate aspects of prosocial behavior, and additionally investigates whether individuals’ social value orientation moderate...

The research on electromechanical transient stability of power systems is great significance. Analyzing the parameters simulation system and its improved with typical short-circuit faults, this paper studies improvement. Firstly, based SIMULINK MATLAB, a double-loop single-machine-infinite-bus built. experiments under circumstances three-phase short circuit single-phase grounding faults are the...

BACKGROUND AND PURPOSE Activity of the trunk muscles is essential for maintaining stability of the lumbar spine because of the unstable structure of that portion of the spine. A model involving evaluation of the response of the lumbar multifidus and abdominal muscles to leg movement was developed to evaluate this function. SUBJECTS To examine this function in healthy persons, 9 male and 6 fem...

The research paper investigates the behaviour of tourism alumni at the transition from tourism education market to tourism labour market and from tourism labour market to other labour markets. The paper focuses especially on the decisions of tourism graduates to enter in the tourism labour market as "stayer" or to exit the tourism industry as "mover". The first part commences with some facts an...

Non-uniform heating of fresh fruit caused by variations in radio frequency (RF) fields is a major obstacle in developing postharvest insect control treatments based on RF energy. A fruit mover was developed to evaluate possibilities to improve RF heating uniformity of large fruit, such as oranges and apples, in a 12 kW batch type RF system. This fruit mover provided a means to rotate and move f...

The use of Universal type motors is very commonly used, both in daily life and research activities. universal motor can be used as prime mover generator PMSG (Permanent Magnet Synchronous Generator), which its application there are obstacles, namely the difficulty stabilizing speed due to influence changes load connected PMSG, this affects output voltage generated by system. In case, a stabiliz...

The performance of a multistage centrifugal compressor is highly influenced by the ambient conditions, especially during summer seasons; their capacity shrinks and thus power requirement for compression will increase. prime cause these constraints interstage cooling limitations. This study simulates various suction conditions on Aspen HYSYS® suggests its debottlenecking making temperatures comp...
