Mechanical vibrations are often the principal cause of image degradation. Low temporal-frequency mechanical vibrations involve random image degradation that depends on the instant of exposure. Exact restoration requires the calculation of a specific filter unique to each vibrated image. To calculate the restoration filter for each image, one needs the specific optical transfer function unique t...

The utilization of electric vehicles has been suggested to support the frequency regulation of power system. Assuming that an intermediate aggregator exists, this study suggests a decentralized vehicle-to-grid operation scheme in which each vehicle-to-grid aggregator can behave independently of the power system operator. To implement this type of decentralized operation, this study adopts a pri...

Multispectral images consist of multiple channels, each containing data acquired from a different band within the frequency spectrum. Since most objects emit or reflect energy over a large spectral bandwidth, there usually exists a significant correlation between channels. Due to often harsh imaging environments, the acquired data may be degraded by both blur and noise. Simply applying a monoch...

Energy generation and consumption in the power grid must be balanced at every single moment. Within synchronous area of continental Europe, flexible generators loads can provide Frequency Containment Reserve Restoration marketed through balancing markets. The Transmission System Operators use these flexibilities to maintain or restore frequency when there are deviations. This paper shows future...

in this paper, the competition between two supply chains and their elements is studied. each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...

This paper presents a new non-iterative, closed-form approximation to the maximum entropy (M.E.) image restoration method. A fast frequency domain implementation of this closed form approach is developed for the case of circular convolutional blur. This result dramatically reduces computational demands compared to conventional iterative M.E. algorithms such as MART. Some limitations and advanta...

Cloud Computing is a new application model for decentralized computing which can provide reliable, customized and maximum number of users with minimum resource. The development of cloud computing marks a great leap towards designing a unified, open and flexible educational information platform, sharing educational resources, and diminishing gaps in the use of educational information. This paper...

Restoring forest landscapes is critical in the face of continued global forest loss and degradation. In this article, we explore some challenges underlying the delivery of global commitments to restore forest landscapes. We propose that three fundamental questions need to be resolved upfront for the effective implementation of Forest Landscape Restoration and related commitments: (1) What socia...

This paper presents thc results of a perceptual test to evaluate the quality of different audio restoration algorithms based on Short Time Spectral Attenuation method and on Kalman filter. The protocol by International Communication Union (1TU.R P.800) was used. A set of audio stimuli played with different instruments (i.e. different bandwidths, transients, and timbre) was selected and differen...

Due to the line impedance impact on islanded low-voltage microgrids, traditional droop control cannot guarantee the proper power sharing between distributed generation (DG) units. In the meanwhile, droop control would cause voltage and frequency deviation, which will influence the power quality of customers. This paper proposed an enhanced droop control scheme with autonomous frequency restorat...
