Testing of database application is crucial for ensuring high software quality as undetected faults can result in unrecoverable data corruption. Conventionally database application testing is based upon whether or not the application can perform a set of predefined functions. While it is useful to achieve a basic degree of quality by considering the application to be a black box in the testing p...

The implementation of reliable and efficient geometric algorithms is a challenging task. The reason is the following conflict: On the one hand, computing with rounded arithmetic may question the reliability of programs while, on the other hand, computing with exact arithmetic may be too expensive and hence inefficient. One solution is the implementation of controlled perturbation algorithms whi...

Adult mesenchymal stem cells (MSCs) are adherent stromal cells able to self-renew and differentiate into a wide variety of cells and tissues. MSCs can be obtained from distinct tissue sources and have turned out to be successfully manipulated in vitro. As adult stem cells, MSCs are less tumorigenic than their embryonic correlatives and posses another unique characteristic which is their almost ...

The reconfigurable manufacturing system (RMS) is a new technology and paradigm that resolves the contradictions regarding high efficiency, low cost flexible production in mass of part families. Reconfigurable machine tools (RMTs) are core components RMSs. A approach proposed for design RMTs, which closely related to process planning given box-type family. concepts processing unit segment presen...
