The application of regular condition checks and continuous monitoring of power transformers gains in importance. Nowadays, these methods are frequently used to detect damages in the insulation system at early stage and thus to avoid outages. In addition to the electrical partial discharge (PD) measurement according IEC 60270 [1], the electromagnetic measurement method starts to become common pr...

PURPOSE The purpose of the study was to identify predictors and outcomes of adult medical-surgical patients' perceptions of their readiness for hospital discharge. DESIGN A correlational, prospective, longitudinal design with path analyses was used to explore relationships among transition theory-related variables. SETTING Midwestern tertiary medical center. SAMPLE 147 adult medical-surgi...

In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...

circular- crested weirs are employed for flow measurement among their other wide applications in hydraulic engineering. they can also be used to control water level in farm ponds and reservoirs. advantages of the circular crested weirs as compared to other weirs include the stable overflow pattern, the simplicity of design and their associated lower costs. in this study, the curvilinear flow pa...

with regard to the importance of instantaneous peak discharge estimation for watershed management study, and due to the lack of and unqualified climatic and hydrologic data for estimation and measurement in countries such as iran, researchers were obliged to establish a link between constant parameters (geomorphologic) and variables (hydrologic) to present models with minimum dependence on clim...

The production of helium 2 1S singlet metastable atoms has been investigated using a hollow cathode discharge and a Penning discharge, under dc discharge conditions. The density of metastable atoms was measured by atomic absorption using the 2 1S–3 1P transition (501.57 nm). A range of plasma currents, varying from 16 to 180 mA, and a range of pressures, from 100 mTorr to 5 Torr, were investiga...

The measurement of phase resolved partial discharge requires a gigantic memory capacity to store all the waves of the PD test results. This limitation eventually hinders the testing. It is necessary to optimize on the aspect of memory storage capability to reduce the storage requirements. In light of foregoing, the partial discharge data retrieval techniques with sampling rate methods were used...

flow-rate measurement in rivers under different conditions is required for river management purposes including water resources planning, pollution prevention, and flood control. this study proposed a new discharge estimation method by using a mean velocity derived from a 2d velocity distribution formula based on tsallis entropy concept. this procedure is done based on several factors which refl...
