We present robust dynamic resource allocation mechanisms to allocate application resources meeting Service Level Objectives (SLOs) agreed between cloud providers and customers. In fact, two filter-based controllers, i.e., $\mathcal {H}_{\infty }$ filter Maximum Correntropy Criterion Kalman (MCC-KF), are proposed. The control...

This paper describes a set of CPU usage analysis tools, named CPU Probes, with the benefits of both hardware and software tools, and few of their disadvantages. CPU probes use a serial line unit or programmable interval timer as a clock to sample the CPU usage of a system, resulting in fast and accurate CPU usage estimates. CPU usage can be monitored for all processes simultaneously or as littl...

With the development of rural power market in our country, how to improve the operation more correctly and timely of power quantity collection, transmission and processing becomes a problem. The requirement of equipment in power quantity collection needs new and higher demands. The advantage of using dual-port RAM and main-spare CPU structure, when main CPU running, spare CPU supply monitoring ...

TEAPC is an IBM/Intel-standard PC realization of a CPU temperature-adaptive feedback-control system. The control system adjusts the CPU frequency and/or voltage to maintain a constant set-point temperature. TEAPC dynamically adapts to changing CPU computation loads, as well as any other system phenomenon that affects the CPU temperature. For example, with the specific TEAPC hardware, should the...

Round Robin CPU scheduling algorithm use fixed time quantum in timeshared system. In timeshared system performance is totally depends upon the selection of time quantum. Static time quantum and selection of time quantum both reason in RR CPU scheduling algorithm is disadvantage for the CPU performance. In this paper study the different dynamic RR CPU scheduling algorithm and discuss the selecti...

Since its discovery more than 20 years ago, a lot has been revealed about the biochemistry and physiological behaviour of carboxypeptidase U (CPU). Recent advances in CPU research include the unravelling of the crystal structure of proCPU and revealing the molecular mechanisms for the marked instability of the active enzyme, CPU. The recent development of two highly sensitive assays has cleared...
