The renovation and opening of tram lines in Polish cities recent years provoke comparisons with similar practice long tradition abroad. subject this article is the spatial relationship between multi-family residential complexes a line. Of course, solutions adopted differ from each other, but there clear trend West to bring both elements closer despite environmental costs that rail cause. In mod...

In this paper, a planning problem is analysed for a consolidation transportation system in order to serve different transportation requests (i.e., orders) with different origins and destinations and different characteristics. The considered transportation system is a railway network provided with innovative terminals (where handling operations are realized very much faster than in traditional t...

Two vector–like families QL,R = (U,D,N,E)L,R and Q ′ L,R = (U ,D, N , E)L,R with masses of order 1 TeV, one of which is a doublet of SU(2)L and the other a doublet of SU(2)R, have been predicted to exist, together with the three observed chiral families, in the context of a viable and economical SUSY preon model. The model itself possesses many attractive features which include explanations of ...

Motion planning of mobile robots is a complex problem. The complexity further increases when it comes to path planning in dynamic environments. This paper presents an algorithm for on-line path planning of mobile robots in unknown environments with moving obstacles. A mathematical model is established which considers all the current on-line information of robot as well as nearing obstacles. Par...
