Bi-directional Transmission (or Reflection) Distribution Functions, commonly named BTDFs (and BRDFs), are essential quantities to describe any complex fenestration system in details. They are defined as the ratio of the luminance diffused from a surface el ...
A review, with 9 refs., is given on trace element anal. by mass spectrometry (MS) and potentiometric stripping anal. (PSA). The key question of the problem is detn. of the structure of the samples (i.e. distribution functions and concns. of atoms, mols., c ...
We consider stochastic guarantees for networks with aggregate scheduling, in particular, Expedited Forwarding (EF). Our approach is based on the assumption that a node can be abstracted by a service curve, and the input flows are regulated individually at ...
Using the standard approach of neoclassical theory, a set of relatively simple kinetic equations has been obtained, suited for an implementation in a numerical code to compute a related set of distribution functions. The transport coefficients are then exp ...

The Preisach approach was used to describe the widely observed quadratic field dependence of the direct longitudinal piezoelectric coefficient and its associated hysteresis loop. In this perspective, a four parameters distribution function was put forward ...
The translational dynamics of CF3 in liquid helium have been investigated by photodissociating CF3I dissolved in helium droplets consisting of several thousands of atoms. The velocity distribution of CF3 fragments that have escaped from the droplets has be ...
The Java object-oriented programming language has been the subject of an important involvement from programmers and the industry. Especially for applications related to the Web. The problem of such a rapid penetration of Java programs into commercial produ ...
Damage evolution and time-to-failure are investigated for a model material in which damage formation is a stochastic event. Specifically, the probability of failure at any site at time t is proportional to sigma(i)(t)(eta), where sigma(i)(t) is the local s ...
The International Electrotechnical Commission (IEC) decided in 1988 to produce a civil standard on the electromagnetic effects of a high altitude EMP (HEMP). Different documents pertaining to the radiated environment and to specifications and test methods ...
