The behavior of the discrete spectrum of the Schr"odinger operator −\D−V, in quite a general setting, up to a large extent is determined by the behavior of the corresponding heat kernel P(t;x,y) as t→0 and t→∞. If this behavior is powe ...
We present a study of the population of bright early-type dwarf galaxies in the multiple-cluster system Abell 901/902. We use data from the STAGES survey and COMBO-17 to investigate the relation between the color and structural properties of the dwarfs and ...
This paper outlines the conclusion from an analysis of 18 large cave systems around the world, comprising more than 1500 km of conduits. The 3D geometry of complex cave systems have been analysed in relation to their geological context as well as their hyd ...
This contribution analyses the arguments of students in a learning activity entitled "Argue Graph". This activity is intended to make students understand the relationship between learning theories and design choices in courseware development. The analysis ...
To obtain addnl. insight into the release mechanism of the metals in electrothermal atomization at. absorption spectrometry, a quant. relation between the heat of vaporization and the size of the released particles is proposed from the Kelvin equation. The ...
We review the well-known relation between Lucas sequences and exponentiation. This leads to the observation that certain public-key cryptosystems that are based on the use of Lucas sequences have some elementary properties their re-inventors were apparentl ...
A review of publication on the expansion of fluidized bed with the fluid velocity. The well-known Richardson-Zaki equation is applied to develop a more accurate relation linking the apparent drag force Fd, the effective gravitational force Fg, and the void ...
We study the relation between the solutions of two minimization
problems with indebite quadratic forms. We show that a complete link between both solutions can be established by invoking a fundamental set of inertia conditions. While these inertia condit ...
Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that is difficult to assess or interpret. In this chapter, we review the current taxonomies of apraxia and related cognitive and neuro ...
A review with 75 refs. of calorimetric techniques used and results obtained in calorimetric expts. aimed at developing quant. relation between heat release and other important process parameters for potential use in monitoring and controlling tech. bioproc ...
