Load Adjustment and Filtering Based on Process Criticality

چکیده
This paper generalizes the load scaling techniques proposed in [4, 5] for xed-priority real-time applications. A framework is proposed to adjust the system workload by relating the criticality and exibility of a process to the resource allocation problem. A load adjustment procedure based on the approximation algorithm [10] is proposed to maximize the system pro t in an on-line fashion. When the list of allowable con gurations is implicitly given by scalable periodic processes, the corresponding load ltering problems is shown to be NP-complete. We also prove the upper bound of the system pro t and provide a mechanism to balance the schedulability and the maximum pro t of the system.

Determination of Criticality Indexes in the Remanufacturing Process: A GERT-based Simulation Approach
In this paper one of the important “end of life options” (remanufacturing) has been analysed. Among the related studies surveyed the various remanufacturing aspects, less attention has been paid to the stochastic process routing. In this regard, a remanufacturing process routing with stochastic activities is modelled as a GERT network. One of the efficient ways to analyse a remanufacturing proc...

A filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. This design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. The high isolation between output ports is obtained by combining the half mode substrate integrated wa...

In this paper, we propose a Controlled Inductance Power Filter (CIPF) to solve power quality problems in industrial DC power supply systems. This method is based on the theory of magnetic potential equilibrium combined with active hybrid filter technology. Initially the system structure and filter wiring scheme are presented and the equivalent circuit is performed with the mathematical models o...
متن کاملDelay Spoofing Reduction in GPS Navigation System based on Time and Transform Domain Adaptive Filtering
Due to widespread use of Global Positioning System (GPS) in different applications, the issue of GPS signal interference cancelation is becoming an increasing concern. One of the most important intentional interferences is spoofing signals. An effective interference (delay spoof) reduction method based on adaptive filtering is developed in this paper. The principle of method is using adaptive f...
متن کاملAn Adaptive Hierarchical Method Based on Wavelet and Adaptive Filtering for MRI Denoising
MRI is one of the most powerful techniques to study the internal structure of the body. MRI image quality is affected by various noises. Noises in MRI are usually thermal and mainly due to the motion of charged particles in the coil. Noise in MRI images also cause a limitation in the study of visual images as well as computer analysis of the images. In this paper, first, it is proved that proba...
