For a simple one dimensional lattice version of a travelling wave equation, we obtain an exact relation between the initial condition and the position of the front at any later time. This exact relation takes the form of an inverse problem: given the times tn at which the travelling wave reaches the positions n, one can deduce the initial profile.We show, bymeans of complex analysis, that a num...

introduction: among the united arab emirates (uae) population more and more people now consider travelling abroad. this is potentially problematic because travelling enhances exposure between hosts and pathogens and so people that travel are putting their health at risk. this concern makes it necessary that public education is provided to inform people of the risks of travelling abroad so that ...

football medicine has developed in the world in recent years. afc medical committee, established the idea of football medicine travelling fellowship two years ago and provided high-level healthcare services to football players in asian countries. this is a report on my one month experience in a travelling fellowship program for football medicine which is attempting to tell the reader about the ...

Travelling Repairman Problem (TRP) is one variant of the Travelling Salesman Problem (TSP) with the objective function minimizing the total waiting time for customers served by the repairman. Finding TRP solution is very important because it is often encountered in real world cases. In the TRP, a customer requires a fast service that he was satisfied. TRP is a combinatorial problem that require...

The Travelling Salesman problem is one of the most popular problems from the NP set, it is also one of the hardest too. The solution to this problem enjoys wide applicability in a variety of practical fields. Thus it highly raises the need for an efficient solution for this NP Hard problem. However even the most common deterministic solutions to the problem are known to possess an exponential t...
