Results and Open Questions on Dynamic Blocking Problems

چکیده
As a motivation, think of a forest fire. To restrict its propagation, assume that a barrier can be constructed, in real time. This could be a thin strip of land which is either soaked with water poured down from a helicopter, or cleared from all vegetation using a bulldozer, or sprayed with fire extinguisher by a team of firemen. In any case, the fire will not cross that particular strip of land. Here the key point is that the barrier is being constructed at the same time as the fire front is advancing.

Dynamical Behavior of a Rigid Body with One Fixed Point (Gyroscope). Basic Concepts and Results. Open Problems: a Review
The study of the dynamic behavior of a rigid body with one fixed point (gyroscope) has a long history. A number of famous mathematicians and mechanical engineers have devoted enormous time and effort to clarify the role of dynamic effects on its movement (behavior) – stable, periodic, quasi-periodic or chaotic. The main objectives of this review are: 1) to outline the characteristic features of...
متن کاملDynamic Blocking Problems
This paper contains a survey of recent work on dynamic blocking problems. The basic model consists of a differential inclusion describing the growth of a set in the plane. To restrain its expansion, it is assumed that barriers can be constructed, in real time. Here the issues of major interests are: (i) whether the growth of the set can be eventually blocked, and (ii) what is the optimal locati...

متن کاملA comparison between effects of earthquake and blasting on stability of mine slopes: a case study of Chadormalu open-pit mine
Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...
متن کاملA population-based algorithm for the railroad blocking problem
Railroad blocking problem (RBP) is one of the problems that need an important decision in freight railroads. The objective of solving this problem is to minimize the costs of delivering all commodities by deciding which inter-terminal blocks to build and by specifying the assignment of commodities to these blocks, while observing limits on the number and cumulative volume of the blocks assemble...
