The study of spatially explicit integro-difference systems when the local population dynamics are given in terms of discrete-time generations models has gained considerable attention over the past two decades. These nonlinear systems arise naturally in the study of the spatial dispersal of organisms. The brunt of the mathematical research on these systems, particularly, when dealing with cooper...

This paper investigates traveling wave solutions of the spatially discrete reaction-diffusion systems whose kinetics are modeled by the McKean caricature of the FitzHugh-Nagumo model. In the limit of a weak coupling strength, we construct the traveling wave solutions and obtain the critical coupling constant below which propagation failure occurs. We report the existence of two different pulse ...

Travel speed is an intrinsic feature of transport, and enlarging the considered as beneficial. The benefit a increase generally assessed value saved travel time. However, this approach conflicts with observation that time spent on travelling rather constant might not be affected by changes. paper aims to define benefits addresses two research questions. First, how will in person transport work ...

this study was conducted to investigate the effect of soil moisture content in primary tillage and travel speed during disking operation on the performance of an offset disk harrow in a silty clay loam soil. at first, the effect of three soil moisture content ranges of (12-14), (14-16) and (16-18) percent (dry basis) on soil clod size (left from moldboard plowing) was investigated. then, the pe...

using instrumented tractors to monitor and record spatial variations in performance parameters of tractor and implements during field operations, could improve productivity and the tractor efficiency. in the context of precision farming, this information can be used to map spatial variability of the parameters and to find the relations with changes in soil attributes (texture, moisture contents...

2 Abstract In this paper, we proposed a Trajectory Reconstruction Model as an improvement to existing speed-based travel time estimation models. The proposed model utilizes point-based speed data collected by existing Intelligent Transportation Systems (ITS). Using the smoothing scheme proposed in this paper, it is possible to construct a speed surface as a function of space and time. Then, one...

As an important information for traffic condition evaluation, trip planning, transportation management, etc., average travel speed for a road means the average speed of vehicles travelling through this road in a given time duration. Traditional ways for collecting travel-speed oriented traffic data always depend on dedicated sensors and supporting infrastructures, and are therefore financial co...

We prove the existence and uniqueness, for wave speeds sufficiently large, of monotone traveling wave solutions connecting 0 and 1 for a class of N -dimensional lattice differential equations with unidirectional coupling. We also obtain a variational characterization of the minimum wave speed. The class of systems that we study includes as a special case the one-dimensional lattice equation un ...
