During laser cutting the morphology and flow properties of the melt film on the cut front affect cut quality parameters such as cut edge roughness and dross (residual melt attached to the bottom of the cut edge).
In this paper the morphology of the laser cut front generated by fibre lasers was investigated by observation of the ‘frozen’ cut front, additionally high speed imaging (HSI) was employed to study the fluid dynamics on the cut front while cutting.
Its appliance includes: construction of local copies of particular database, which can be synchronized with the global one support of synchronized local copies at a given time possibilities for work without connection with global database copy update from local to global database copy and vice versa conflict detection and resolution during replication logging of synchronizations that are done. The proposed approach could be used as alternative replication method within Microsoft SQL Server 2000. The goal of this paper is design and implementation of an approach, which provides replication and synchronization of several distributed copies of a particular database. A smart solution is using of reliable and efficient replication method. So, the question is: How remote offices could work effectively with shared database. Fast growing markets and development of new technologies require companies to use network of geographically dispersed offices located in different cities and countries.
