The North American Lightning Detection Network (NALDN) is a commercial lightning detection network composed of the U.S. National Lightning Detection Network (NLDN) and the Canadian Lightning Detection Network (CLDN). The NALDN was developed to provide lightning information by accurately detecting and locating most cloud-to-ground (CG) lightning strokes and a small fraction of discharges produce...

The present paper describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. The design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. Once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables....

since the energy analysis considers the quantity of energy, it cannot show the performance of the cooling tower. therefore, in order to optimize the performance of the tower and also the process which the cooling tower is a part of it, it is necessary to analyze the energy and exergy of the tower simultaneously. in this paper, the energy and exergy of one of the cooling towers of khuzestan stee...

The importance of bridge health monitoring and management has been recognized by authorities of long-span bridges throughout the world in recent years. The GeoSHM consortium, led by the University of Nottingham, was awarded a Feasibility Study (FS) grant in 2013 by the European Space Agency (ESA) to investigate how to use integrated GNSS and Earth Observation technologies for the structural hea...

ghorban tower as an architectural monument is one of the outstanding resting- place of islamic era in hamadan city which has not been studied properly. previous studies on the tower concerning its architectural features or its historical background showed that the tower may be a place where a dignified religious man named khajeh hafez abol'ala hamadani berried inside in saljuk era and afte...

temperature restrictions on aqueous effluents dictate that streams with a temperature higher than the permitted level needed to pass through cooling systems to reduce the effluent temperature before discharge. in this study, by considering the grouping design rules based on pinch technology, an optimum design for a distributed effluent cooling system, has been developed. a counter-flow wet cool...
