Virtualization is commonly used for efficient operation of servers in datacenters. The autonomic management of virtual machines enhances the advantages of virtualization. Therefore, for the development of such management, it is important to establish a method to accurately detect the performance degradation in virtual machines. This paper proposes a method that detects degradation via passive m...

BACKGROUND Treatment failure during highly active antiretroviral therapy (HAART) is ultimately common and associated with the development of resistance mutations to both the specific drug in question and cross-resistance to other available treatment options. In heavily pre-treated patients, the recycling of antiretroviral agents that have been utilized previously may, however, be associated wit...

Voltage source inverters (VSIs) are usually used for all kinds of distributed generation interfaces in a microgrid. It’s the microgrid’s superiority to power the local loads continuously when the utility fails. When in islanded mode the voltage and frequency of the microgrid are determined by the VSIs, therefore the power quality can be deteriorated under unbalanced and nonlinear loads. A volta...

In ATM networks, Virtual Path Connections (VPCs) are not only a device for bundling Virtual Circuit Connections (VCCs), but they serve as an intermediate resource management layer wherein tradeoos between cost, complexity, and eeciency are likely to be made on a slower time scale than connection holding times. In this paper we consider bundling multicast connections on VP trees. In particular, ...

Two clairvoyant virtual-time CSMA/CD protocols for dealing with time-constrained messages are described. A clairvoyant protocol takes into account not only the messages currently available for transmission but also the messages expected to be produced in the future. In the absence of clairvoyancy, the urgent but currently unavailable messages may not be successfully transmitted when they are ac...
