Solar systems are highly penetrating into the electrical networks all over the world currently. Solar radiation is not steady and never will be, and so, a storage system is required to ensure a stable and continuous supply. To increase the reliability of the system whether islanded or network connected, it is better to have a storage system. After all, the decision of whether to use a storage system...
The development of hydraulic fracturing technology has dramatically increased the supply and lowered the cost of natural gas in the United States, driving an expansion of natural gas-fired generation capacity in several electrical interconnections. Gas-fired generators have the capability to ramp quickly and are often utilized by grid operators to balance intermittency caused by wind generation. The...
It has been observed that sometimes in Numeric Association Rule Mining (NARM), it is important to understand the association between a numeric attribute and a specific categorical consequent class attribute. NARM divides the domain of numeric attributes sub-domains without considering particular categorical consequent class attribute. Apart from this, it may also suffer from support-confidence conflict...
AODV protocol is a comparatively more popular on demand routing protocol in mobile ad hoc networks. However, reliability in terms of data communication is not much satisfactory in traditional AODV. This paper presents an AODV with end to end reliability (AODV-EER). The main idea of proposed modification in AODV is to find the route with lowest drop rate from source to destination. We also propose...
The increasing demand for World Wide Web (WWW) services has led to a considerable increase in the amount of Internet traffic. As a result, the network becomes highly prone to congestion which increases the load on servers, resulting in increasing the access times of WWW documents. Thus, web caching is crucial for reducing the load on network, shorten network latency and improve clients' waiting time...
To vanquish the ever increasing demand of energy and trounce the carbon dioxide emission; the human race is looking towards the renewables and nuclear energy as the plausible sources. During the past few years the general public consensus about the later have taken a negative turn; attributed to the Fukushima nuclear disaster. To counter this nuclear unit designers have proposed the idea of Accident...
The standardization of the IEEE 802.15.6 protocol for wireless body area networks (WBANs) dictates the physical layer and medium access control layer standards from the communication perspective. The standard supports short-range, extremely low power wireless communication with high quality of service and data rates upto 10 Mbps in the vicinity of any living tissue. In this paper, we develop a discrete-time...
The purpose of this research is to investigate the factors influencing satisfaction on e-tax filing (e-Revenue) of SMEs in Thailand. The data were collected from 415 respondents using the service. The website service quality dimensions in this study consist of information quality, system quality and service quality. The related hypotheses were tested using structural equation modeling. The researcher...
The paper builds the influential factor model of virtual community knowledge sharing behavior from the four dimensions. By using structural equation model, the paper makes an empirical research on the key factors of promoting the college students' knowledge sharing behavior in the virtual community and the impact of knowledge sharing behavior of virtual community members on the community loyalty.
Virtual connections in packet switched networks is increasing faster, in particular over the Internet, using MPLS and GMPLS evolution has produced a significant amount of studies on traffic engineering protocols, especially with regard to the different ways to provide quality of service over connections. This article presents a model to characterize the reliability of these types of networks, in computing...
In today's large data centers, hundreds to thousands of nodes are deployed as storage clusters to provide cloud and big data storage service, where failures are not rare. Therefore, efficient data redundancy technologies are needed to ensure data availability and reliability. Compared to traditional technology based on replication, erasure codes which tolerate multiple failures provide availability...
Interest in renewable energy resources (RER) is increased due to improved public awareness of the high energy cost and adverse environmental impacts of conventional energy resources. Causes a transition to a new generation of power networks which, among others characteristics, allows more flexible demand consumption under various Demand Response Programs (DRPs). Variable generation and stochastic...
In this paper, we design and test a full distributed and scalable resource-management scheduler for Vehicular Real-Time applications. We dynamically allocate the access time window (at the RoadSide Units) and the access rate and traffic flows (at the Vehicular Clients) under hard reliability collision constraints. We provide the optimal memoryless scheduler for network utility maximization, showing...
We consider a two-channel queuing system with unreliable servers which fail alternately for modeling of hybrid communication systems, which have a millimeter-wave (71–76 GHz, 81–86 GHz) radio channel as a backup communication channel. The stationary distribution of the system states and the most important performance characteristics were obtained.
In this paper, the system of study contains a wind turbine ( asynchronous generator) connected to an AC / DC converter, a static VAR compensator (SVC) represents a variable capacity and an LC filter to supply a resistive load. After the study for each part to our system, modeling and simulation in MATLAB/SIMULINK, so as to achieve a voltage regulation of the wind energy system, we have proposed a...
Micro-grid is the technique which could access the utility grid with combined renewable energy generation resources, loads, energy storage devices and control devices. It is generally agreed that, Micro-grid could reduce or avoid the impact of wide range failure to the users and improves the power supply reliability. This paper proposed a Monte Carlo method to evaluate the reliability of Micro-grid...
In this study 2-layer ANN (artificial neural network) a linear classifier and k-NN (k-nearest neighbor) a non-linear classifier were applied for identification and classification of images of four Indian wheat seed species into four classes of wheat seeds on the basis of their varieties. 120 images (40 images of four classes, 10 images of each class) from three different places were taken under same...
The sensitivity analysis of systems' characteristics to the shape of distributions is a very important task of reliability engineering of stochastic systems and networks. One of the earliest result concerning insensitivity of systems' characteristics to the shape of service time distribution was obtained in case of Erlang's formulas for loss queues with Poisson arrival stream, where steady-state distribution...
This paper proposed a reliability evaluation algorithm for distributed generating system based on sequential state duration sampling method. The power output fluctuation of distributed resources, chemical reaction constraint of energy storage device, and the power exchange strategy with the utility grid are taken into consideration. The method produces the time-varied status of all the elements in...
Over the past few years, the relationship between attitudes and behavior has been of a major interest to educators. Previous studies have found varying degree of associations between attitudes, behavioral intention and perceptions and corroborate the fact that attitudes influence patterns of behavior. As computer technology is becoming pervasive in the society, researchers have attempted to explore...
