On the basis of the elementary laws of individual driver behavior concerning the acceleration and interaction of vehicles a gas-kinetic traffic model is constructed. This yields theoretical relations for the fundamental diagram and the equilibrium variance-density relation, but above all it allows the derivation of macroscopic traffic equations. These build a hierarchy of non-closed equations w...

Models of gamma ray bursts are reviewed in the light of recent observations of afterglows which point towards a cosmological origin. The physics of fireball shock models is discussed, with attention to the type of light histories and spectra during the gamma-ray phase. The evolution of the remnants and their afterglows is considered, as well as their implications for our current understanding o...

Simple theoretical models can be constructed to study the behavior of sensor-fused systems using idealized sensor suites. Models are available for feature-level and decision-level fusion, both of which are now being used with demining sensors. These models are attractive as design tools and for estimating the expected performance of new sensor suites, since their performance can be evaluated wi...

This article presents the theoretical analysis of Inverse Generalized Exponential Models. The shapes of the properties of the Inverse Generalized Exponential distribution are discussed. Inverse moments of Inverse Generalized Exponential distribution are derived. In this article we have presented the relationship between shape parameter and other properties such probability distribution, distrib...

For several decades, economists have used the annual demand for trips in order to measure the nonmarket value of recreation sites. Two features of trip demand functions complicate their estimation: trip demand is nonnegative and occurs in integer quantities. The fact that trip demand cannot be negative results in a censored (at zero) data set; failure to account for censoring leads to biased es...

In the past four decades, research of new product development has attracted attention from both academia and practitioners. The success of new product development has been regarded as one important source of firms’ competitive advantage (Krishnan & Ulrich, 2001; Luo, Kannan, Besharati, & Azarm, 2005). In order to guide decision making in product design, several consumerdriven methodologies, suc...

Fifteen years ago, Monique Tirion showed that the low-frequency normal modes of a protein are not significantly altered when nonbonded interactions are replaced by Hookean springs, for all atom pairs whose distance is smaller than a given cutoff value. Since then, it has been shown that coarse-grained versions of Tirion's model are able to provide fair insights on many dynamical properties of b...

We survey the main theoretical aspects of models for Mobile Ad Hoc Networks (MANETs). We present theoretical characterizations of mobile network structural properties, different dynamic graph models of MANETs, and finally we give detailed summaries of a few selected articles. In particular, we focus on articles dealing with connectivity of mobile networks, and on articles which show that mobili...

other directions. In the spirit of Brindley (1970), we should first confirm the plausibility of these hypotheses by correlating properties of neural events with corresponding properties of perceptual phenomena. This is a straightforward task in the case of motion perception and aftereffects. Data from direct cell recordings show that the middle temporal area (MT ) in primates is particularly ri...
