NASA’s Solar Probe Plus (SPP) mission will make the first in situ measurements of the solar corona and the birthplace of the solar wind. The FIELDS instrument suite on SPP will make direct measurements of electric and magnetic fields, the properties of in situ plasma waves, electron density and temperature profiles, and interplanetary radio emissions, amongst other things. Here, we describe the...
Electric vehicle has received more and more extensive attention, which is one of the major development directions of motor vehicles using new energy sources. Electric vehicles are development promising green transports, and important means to solve energy and environmental problems. The construction of charging infrastructure is an important prerequisite for the advancement of electric vehicles...
In the extremely low frequency range (3 to 300 Hz), the intensities of electric and magnetic fields increase with increasing voltage and current. If the intensities of electric and magnetic fields are high compared with standard exposure limits, they can have harmful effects on human health. In the vicinity of power lines and high voltage power stations, the intensities of these fields are usua...
Abstract Electric vehicles are growing in popularity and reviving a much disused powertrain the vehicle sector. This paper deals with measurement of driving performance electric vehicles. For twelve selected vehicles, parameters given by manufacturer measured during individual runs were compared. The measurements carried out on predetermined route, divided into several parts. data obtained here...
This paper establishes a standard method for measuring human tremor. The electronic instrument described is an application of this method. It solves the need for an effective and simple tremor-measuring instrument fit for wide distribution. This instrument consists of a piezoelectric accelerometer connected to an electronic circuit and to an LCD display. The signal is also analysed by a compute...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
This paper presents a general object-oriented model for measurement systems. The limitations of the conventional function-oriented models are examined in the light of the generalized concept of measurement and its theoretical framework proposed previously by the authors. The proposed model identifies five classes of objects, i.e., measured object, measuring instrument, reference standard, human...
With the increasing use of particle accelerators in various fields, construction has developed. In these accelerators, measurement instruments that measure important and versatile quantities are very important. Due to role electric potential acceleration, accurate at any time is essential. this research, design, fabrication testing a non-destructive measuring device called Generating Voltmeter ...
