Adjustable throat-area expansion valves (ATAEV), including thermostatic and electric expansion valves, are used commonly in air conditioning equipment and lead to improved system performance as compared with the use of fixed orifice expansion devices. However, ATAEV modeling literature is limited. Typically, a TXV is modeled by specifying the superheat entering the compressor or empirically cor...

Several standards exist for testing the radiated “over air” (OTA) performance of 5G User Equipment (UE) devices. All these are limited to a Single-Input Single-Output (SISO) evaluation device. With networks and devices already deployed in operation, it becomes necessary develop realistic Multiple-Input Multiple-Output (MIMO) beamforming metrics UEs. Since most important feature is beamforming, ...

Material handling equipment plays an important role in the design and development of advance manufacturing systems (AMS) like flexible manufacturing systems. Material handling equipments affects the performance and productivity of these advance manufacturing systems. So it becomes very important to select a right kind of equipment while designing the high end manufacturing systems like FMS. In ...

Video recording of construction operations provides an understandable data that could be used to analyze and improve construction performance. Despite the benefits, manual stopwatch study of previously recorded videos can be laborintensive, may suffer from biases of the observers, and impractical after substantial period of observations. To address these limitations, this paper presents a new v...

Abstract Background: In 2007, a rule prohibiting the use of incinerators was ratified by the Iranian Islamic Parliament. Based on this rule, the Ministry of Health emphasized the sterilization of infectious waste at its production source by means of non-incineration equipment and methods. This research examined the performance of non-incineration technologies in treating medical infectious and ...
