The detection and diagnosis of faults in technical systems are of great practical significance and paramount importance for the safe operation of the plant. The early detection of fault can help avoid system shutdown, breakdown and even catastrophe involving human fatalities and material damage. Since the operator cannot monitor all variables simultaneously, an automated approach is needed for ...

Pad and fan cooling systems are the most popular evaporative cooling system, especially in the floral industry of tropical and subtropical regions. Microsoft Windows based software written in MATLAB was developed as a teaching/research tool for designing pad and fan systems. This software incorporates information for 4 models of commonly used evaporative cooling pad, fan curves for 9 models of ...

Selective emittance materials show high technical potential for use as radiative cooling heat exchangers for buildings. This paper presents the thermal modeling of the photonic radiative cooler and the simulation of a system that integrats the photonic radiative cooler with radiant floor cooling in a medium office building. The system was simulated with EnergyPlus and the extensive use of its e...

We present the first remotely operated vehicle investigation of megabenthic communities (1004-1695 m water depth) on the Hebrides Terrace Seamount (Northeast Atlantic). Conductivity-temperature-depth casts showed rapid light attenuation below the summit and an oceanographic regime on the flanks consistent with an internal tide, and high short-term variability in water temperature, salinity, lig...

Analysis of sunlight, which started the discipline of spectroscopy, has been the key to a number of major scienti® c discoveries. Sunspots, which are much cooler than most of the Sun’s surface, have particularly rich and complicated spectra which has long been thought to be due to very hot water. The challenge of analysing this spectrum has stimulated the development of new theoretical procedur...

From 1983 to 2002, the Indiana Cooler was constructed and operated at the Indiana University Cyclotron Facility. During that period, a relatively small group of people built an accelerator complex, explored the new technology of electron cooling, and demonstrated its usefulness in nuclear and particle physics. This review recounts the history of the project, describes the facility, and summariz...

Abstract A theoretical study is developed to examine the feasibility of using cooling tower and coil with direct evaporative cooler in highest summer temperature Karbala/Iraq. This due inability reducing outside air efficiency reduction mechanical vapor compression systems despite its high electrical energy consumption at temperatures. The water cooled a higher than outdoor wet-bulb by (3.9 $$^...
