Recent developments in photo-detectors and photo-detector systems are reviewed. The main emphasis is made on Silicon Photo-Multipliers (SiPM) novel and very attractive photo-detectors. Their main features are described. Properties of detectors manufactured by different producers are compared. Different applications are discussed including calorimeters, muon detection, tracking, Cherenkov light ...

The first Micro Gallery opened at the National Gallery in London on July 21st 1991. The first facility of its kind, it provided visitors with a comprehensive multimedia reference to the Gallery's collection. Since then the author and his colleagues have had the privilege of working on two further projects of a similar nature. The Image Gallery at the San Diego Museum of Art opened on October 26...

background: the appropriate designing of school equipment for establishing a suitable sitting habit, is of major importance. unfortunately, benches and desks in iranian schools are not properly adjusted with anthropometric characteristics of students. the main theme of this research is preparing some guidelines for anthropometric designing and ergonomic adjustment of benches and desks. methods:...

We present a measurement of the rate of gluon splitting into bottom quarks, g → bb̄, in hadronic Z decays collected by SLD from 1996 to 1998. The analysis was performed by looking for secondary bottom production in 4-jet events of any primary flavor. A topological vertex mass technique was used to tag the two jets with the smallest angle between them as b/b̄. We obtained a rate of g → bb̄ per hadr...

We consider combinatorial problems motivated by sensor networks for beacon-based point-to-point routing and covering. A beacon b is a point that can be activated to effect a ‘magnetic pull’ toward itself everywhere in a polygonal domain P . The routing problem asks how many beacons are required to route between any pair of points in a polygonal domain P . In simple polygons with n vertices we s...

Gender has been unmasked as a key determinant of body adiposity and endocrine homeostasis in the human fetus. Increasing evidence suggests that girls are more insulin resistant than boys at all ages from birth to adolescence[1-3]. Furthermore, type 2 diabetes in children is commoner in girls than in boys[4]. These gender based differences seen early in life could reflect differences in intrinsi...

The traditional individual 3D virtual humand modeling method has drawbacks of mass data and complex post-processing. It doesn’t suit the Web application. The research presented in this paper is to propose a novel real-time approach of 3D human parameterized modeling based on anthropometry. According to the principle in Anthropometry and Anatomy, the model surface is divided into several parts. ...

Introduction: The findings of cephalometry studies are widely applied in medical and engineering fields. Cephalometry measurements are affected by genetics‚ age‚ gender‚ and social‚ economic and geographic factors.This study assesses cephalometry of the neurocranium in male newborns in Kermanshah,Iran by an anthropometry method to confirm or reject the theory of brachycephalization (i.e., ...
