Measurement of hailfall intensity with a self‐contained hailstone momentum sensor

Measurement of Perceived Odor Intensity Using Gas-Sensor Systems

In the present study Multi gas-sensor systems (MGSS) are used to evaluate the odor intensity as it is perceived by humans. These systems measure volatile compounds in a holistic manner and present a signal pattern of the air sample. The model for the determination of the odor intensity consists of two major parts: discrimination into odor classes and subsequent quantification of the intensity. ...

A Simple Fiber Optic displacement Sensor for Measurement of Light Intensity with the Displacement

Abstract Over the last two decades, the fibre optic technology has passed through many analytical stages. Some commercially available fibre optic sensors are being used for automation in mechanical and industrial environments. They are also used for instrumentation and controls. In the present work, a fibre optic displacement sensor is presented. This type of sensor is an intrinsic sensor. In t...

A Statistical Model for the Incidence of Large Hailstones on Solar Collectors

AMtraet--A statistical model is described for estimating the risk of impacts by large hail on any ground installation (such as a solar collector array). The model is based on data for three frequency distributions: hailstone size, hailfall count (number of hailstones per m 2 per storm), and number of haildays per year. Other than parameters derived from meteorological data, the parameters of th...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
