This note derives a general, exact formula for the covariance of products of the spacings of a uniform sample in order to determine their order of magnitude. It compares the results with an estimation of the order obtained by applying the Cauchy--Schwarz i ...
Consider a network with an arbitrary topology and arbitrary communication delays, in which congestion control is based on additive-increase and multiplicative-decrease. We show that the source rates tend to be distributed in order to maximize an objective ...
We consider an electron-phonon system in two and three dimensions on square, hexagonal, and cubic lattices. The model is a modification of the standard Holstein model where the optical branch is appropriately curved in order to have a reflection positive H ...
Performing 3D interactions with virtual objects easily becomes a complex task, limiting the implementation of larger applications. In order to overcome some of these limitations, the paper describes a framework where the virtual object aids the user to acc ...
The kinetics for homogeneous hydrolysis of mannan was studied in a batch reactor at temps. from 160 to 220 Deg. A formate buffer ensured a pH of 3.8-4.0, measured at 25 Deg. Samples were analyzed for oligosaccharides at a d.p. of ?6 and also for the total ...
Photodynamic therapy (PDT) is a new treatment modality which relies on a nonthermal light exposure of choroidal neovascularization (CNV) which has accumulated a photosensitizer, to produce a photochemical thrombosis. The aim of the present study was to dev ...
This paper deals with multiwavelets and the different properties of approximation and smoothness that are associated with them. In particular, we focus on the important issue of the preservation of discrete time polynomial signals by multiwavelet based fil ...
Since the mid 1990s, network and systems management has steadily evolved from centralized paradigms, where the management application runs on a single management station, to distributed paradigms, where it is distributed over many nodes. In this survey, ou ...
Systems that support mobile agents are increasingly being used on the global Internet. An important application that is considered for these agents is electronic commerce, where agents roam the World Wide Web in search of goods for their owners. In these a ...
This paper describes an evolutionary algorithm based on a statistical representation of populations of individuals. Experiments on robot navigation and on numerical fitness functions are presented in order to measure the performance of the algorithm compar ...
