Mobile networks pose new issues in the field of distributed garbage collection. Garbage collection must deal with volatile connections that may break remote object references unexpectedly for an unpredictable amount of time. As a result, no automatic distributed garbage collection satisfies the new hardware phenomena. A semantic-based approach called semi-automatic garbage collection is propose...

Several garbage collection algorithms exist, but it is not always straightforward to adapt them to a given platform. In this article, we describe our work to t a distributed garbage collection algorithm to a persistent distributed store called PerDiS. We pinpoint ordering and consistency problems, and present the way we solved them. We also address the dilemma of performance versus modularity.

by drawing blood through a heparin lock, patients can be protected from skin damages duo to repeated needle sticks. in addition, this procedure can assist to gain more precise results in laboratory test and to prevent further complications. probably, you have ever used a heparin lock in order to infusion of medicines but, it is possible that you never use of that for blood sampling. both two pr...
