this paper presents a new modified shuffled frog leaping algorithm (msfla) applied to design simultaneous coordinated tuning of damping controllers to damp the power system low frequency oscillations. for this, a new frog leaping rule is proposed to improve the local exploration and performance of the original sfla and the genetic mutation operator is employed for new frog generation instead of...

An accurate average value model of synchronous machine-rectifier system considering the effect of stator resistance is derived in this paper. A proper voltage-behind-reactance synchronous machine model without any approximations is used for the generator that allows effective calculation of commutation displacement angle. All rectification modes of the rectifier are studied. A detailed switchin...

Logos analyzes whole source sentences, considering morphology, meaning, and grammatical structure and function. The analysis determines the semantic relationships between words as well as the syntactic structure of the sentence. Parsing is only source language-specific; generation is target language-specific. Although the Logos system was originally developed on the basis of a transfer approach...

honey is a sweet and viscous liquid made by bees from nectar of flowers. the emitted smell by honey depending on flower variety can be different. these factors led to use of machine olfactory system based on metal oxide sensors(mos) in order to classify different floral origin honeys. seven samples of different floral origins of honey with a total of 70 samples from each of 10 samples were test...

this paper analyzes a controllable discrete-time machine repair problem withl operating machines and two repairmen. the number of working servers can be adjusteddepending on the number of failed machines in the system one at a time at machine's failure orat service completion epochs. analytical closed-form solutions of the stationary probabilities ofthe number of failed machines in the sys...

A Machine Protection System implemented on the SLC automatically controls the beam repetition rates in the accelerator so that radiation or temperature faults slowthe repetition rate to bring the fault within tolerance without shutting down the machine. This process allows the accelerator to aid in the fault diagnostic process, and the protection system automatically restores the beams back to ...

Introduction: Very low, Low and Medium X-ray machines are used extensively for Superficial Radiation Therapy mostly used for Basal Cell, Squamous Cell Carcinoma, and Melanoma skin cancers. In most of cases, Superficial X-ray Therapy (SXRT) is preferred to Electron beams generated using a linear accelerator. SXRT tube characteristics may vary with the use of the machine for a lo...

Artificial Immune Systems (AIS) can be defined as soft computing systems inspired by immune system of vertebrates. Immune system is an adaptive pattern recognition system. AIS have been used in pattern recognition, machine learning, optimization and clustering. Feature reduction refers to the problem of selecting those input features that are most predictive of a given outcome; a problem encoun...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...
