Detecting and diagnosing HVAC faults is critical for maintaining building operation performance, reducing energy waste, ensuring indoor comfort. An increasing deployment of commercial fault detection diagnostics (FDD) software tools in buildings the past decade has significantly increased buildings’ operational reliability reduced consumption. A massive amount data been generated by FDD tools. ...

Abstract The proposed Remote SCADA System (RSS) is a smarter, faster and more reliable way to control high power machines monitor their sensors, data, failures. system focuses mainly on building our own complete software not using open-source software. RSS can use unlimited number of added Terminal Units (RTU) nodes each them handling input/output be used under different operating systems like ...

For the single-pair HDSL (HDSL2), the concept of having different upstream and downstream power spectral densities is highlighted. The signal-to-noise ratio (SNR) at the input of the central office HDSL terminal unit (HTU-C) can be enhanced by boosting the power output of the remote user HDSL terminal unit (HTU-R). Further improvement in performance can be achieved by reducing the HTU-C NEXT in...

If 4-20 mA is used, make sure to specify 4-20 mA AI and AO cards which support native HART “pass-through”. Thus separate HART multiplexer (MUX) hardware and associated integration work is not required. Native HART pass-through AI and AO cards are much easier to integrate. HART communication is too slow for control, but is passed through to the IDM software. Be wary of proprietary smart protocol...

Most heating, ventilation, and air-conditioning (HVAC) systems operate with one or more faults that result in increased energy consumption could lead to system failure over time. Today, most building owners are performing reactive maintenance only may be less concerned able assess the health of until catastrophic occurs. This is mainly because do not previously have good tools detect diagnose t...

BACKGROUND Myocardial ischemia creates abnormal electrophysiological substrates that result in life-threatening ventricular arrhythmias. Identifying patients at risk of such abnormalities by use of body surface electrical measures is controversial. We investigated the sensitivity of torso measures, recorded simultaneously with epicardial electrograms, to changes in dispersion of depolarization ...

INTRODUCTION In 2011, the first radiotherapy centre in Western NSW Local Health District (WNSWLHD) was opened in the city of Orange. Prior to this, patients travelled outside the health service, primarily to Sydney, to receive treatment. The aim of this study was to investigate if the establishment of the new rural radiotherapy service has changed the demographic profile, cancer type, treatment...

Thirty years have passed since Pfeffer and Salancik’s seminal work on resource dependence theory (RDT). During this time RDT has been applied broadly across the research domain to explain how organizations reduce environmental interdependence and uncertainty. In this review, the authors assess the conceptual development, empirical research, and application of RDT. They structure their review ar...
