We propose a simulation approach which applies time-stepped and fluid simulation techniques to accelerate large-scale simulations of mobile ad hoc networks (MANETs). We described the simulation modelling and parameterizing process according to the dynamic characteristics of MANETs. We also introduce the simulator SSim developed by the authors and present the experiment results. This research de...

This paper proposes an improved angular stepped generalized Radon Fourier transform (angular-stepped-GRFT) algorithm for maneuvering weak target detection in synthetic wideband radar. The proposed method can achieve motion parameters estimation the based on frequency signal. On this basis, compensation of and range profile focusing are realized.

A multimodal stepped care approach has been successfully applied to a patient with complex regional pain syndrome type 1 and severe intractable pain, not responding to regular neuropathic pain medication. The choice to administer drugs in creams was made because of the intolerable adverse effects to oral medication. With this method, peak-dose adverse effects did not occur. The multimodal stepp...

We consider a substitutive version of the Arnoux-Yoccoz Interval Exchange Transformation (IET) related to the Tribonacci substitution. We construct the so-called stepped lines associated to the fixed points of the substitution in the Abelianisation (symbolic) space. We analyse various projections of the stepped line recovering the Rauzy Fractal, a Peano Curve related to the work of Arnoux [1], ...

Water-metal interfaces are ubiquitous and play a key role in many chemical processes, from catalysis to corrosion. Whereas water adlayers on atomically flat transition metal surfaces have been investigated in depth, little is known about the chemistry of water on stepped surfaces, commonly occurring in realistic situations. Using first-principles simulations, we study the adsorption of water on...

The stepped leader forms the first phase of the first stroke in any lightning flash. It is basically a stepwise elongating discharge in air, which carries significant charge. The charge distribution on the leader and its velocity of descent determine the attractive radius in shielding efficiency calculations. Also, the conductivity and the charge distribution on the leader tip region govern the...

Air-water flow measurements were conducted in two large-size stepped chute facilities (θ = 3.4 & 16o) to study experimental distortion caused by scale effects and result extrapolation to prototypes. The stepped geometries corresponded to moderate slopes typical of embankment dams and storm waterways. Experimental data included distributions of air concentration, air-water flow velocity, bubble ...

The main objective of the present paper is to derive an easy numerical technique for the analysis of the free vibration through the stepped regions of plates. Based on the utilities of the step by step integration initial values IV and Finite differences FD methods, the present improved Initial Value Finite Differences (IVFD) technique is achieved. The first initial conditions are formulated in...

Only very special subclasses of probability distributions can be used for qualitative reasoning that meets basic logical demands. Snow’s atomic bound systems (big-stepped probabilities) provide one positive example for such a subclass. This paper presents a thorough investigation of the formal logical relationships between qualitative and probabilistic default reasoning. We start with formalizi...

A computational efficient approach to identify very small mine-shaped plactic objects, e.g. M56 AntiPersonnel (AP) mines buried in the ground, is presented. The size of the objects equals the smallest AP-mines in use today, i.e., the most difficult mines to detect with respect to humanitarian mine clearance. Our approach consists of three stages, the phase stepped-fiequency radar method, genera...
