Yield and loss prediction plays an important role in the planning and operation of solar PV systems. The performance of a solar PV system depends on the location, system design, field of view, and the orientation of the solar panels in a given system. Some design and simulation tools are designed by professionals to connect to efficient planning and grid operations as well as stand-alone solar photovoltaic...
India is world's third largest producer of electricity with an installed capacity of 306 GW. However, the per capita electricity consumption in India continues to be well below the world average despite lower electricity tariffs. The nation has a long history of demand-supply shortages on a regular basis. The electricity distribution sector is also under poor financial condition. With an energy mix...
Selecting the right cloud service provider is crucial to minimize the downtime/outage risk and prevent Service Level Agreement (SLA) violation. The main purpose of this paper is to introduce a framework to identify and control the associated risks using requirements, priorities, service level parameters, and cost in order to identify eligible cloud providers. The methodology uses Value at Risk (VaR)...
Modern industrial system is becoming more and more complex in order to produce the goods with high quality or achieve the functional requirements set by human beings. However, once the faults occur in the system, it's highly possible that the financial losses and even the operators' death may be caused. Therefore, it's necessary to improve the reliability of the system. The data-based fault diagnosis...
In recent years, trust has emerged with the development of cloud computing. It is a critical step to select a trusted cloud provider before the service begins, which is related to the interests of cloud consumers themselves and the quality of the service. A SLA trust model based on behavior evaluation is proposed in this paper. User's subjective evaluations are abandoned, the provider who is trusted...
A new efficient measure for predicting estimation accuracy is proposed and successfully applied to multistream-based unsupervised adaptation of ASR systems to address data uncertainty when the ground-truth is unknown. The proposed measure is an extension of the M-measure, which predicts confidence in the output of a probability estimator by measuring the divergences of probability estimates spaced...
As it is important to evaluate the performance of the Digital Substation, So The objective of first part of this paper is to evaluate the reliability and availability of protection functions for practical substation architecture using RBD method based on different configuration. RBD is a success-oriented network simplifying the function of the system by showing the logical connections among system...
SpaceWire is a full-duplex, point-to-point, high-speed serial data transfer standard which is intended for use in further on-board spacecraft, space missions and applications. However, space environment is harsh and complex which requires a communication network with high reliability. It is inevitable that SpaceWire network link fault or SpaceWire equipment damage is able to change the SpaceWire network...
In recent years, the theory and method of wavelet analysis is widely used in signal processing, pattern recognition, data compression, image processing and quantum physics. Compared with modulus maxima, wavelet packet decomposition and coefficient shrinkage de-noising method of wavelet transform, their advantages and disadvantages are analysed and summarized, and their respective scopes are obtained...
In order to realize the function of accurate measurement, multipoint collection and wireless transmission on various environmental monitoring factors in the workshop, a workshop environment monitoring system is proposed based on the technology of internet of things. A number of wireless monitoring nodes are set up in each workshop to collect a variety of environmental information, then transmit the...
In this paper, we aim to develop an efficient speculation framework for a heterogeneous cluster. Speculation is a common mechanism that identifies ‘slow’ node in a cluster and starts redundant tasks on other nodes to guarantee the reliability. We consider MapReduce/Hadoop as a representative computing platform, and our general goal is to accurately and quickly identify the straggler nodes during the...
In a collaboration, trust is of great importance for the substantial governance of the inter-organizational activities. In this paper, considering changes of collaboration situations, an on-going trust model is established for a better understanding of the dynamics of relationship. Determinants of the on-going trust condition are also gathered and structured in two clusters. Those are ‘initial trust...
With the speedy developing of automotive market, the demand of automotive electronics semiconductor becomes more tremendous. Traditional semi-automatical equipment management method became unsuitable in semiconductor manufacturing. This paper tries to explain how to set up a high efficiency and accuracy assessment methodology on equipment performance to come out best tools on automotive semiconductor...
System Protection Schemes (SPS) are considered as an effective tool for enhancing the resilience of the power system towards rare contingencies. The validation of SPS is difficult by using conventional SCADA data due to its inherent low scan rate and skewedness. Under such condition, Synchrophasors has been found to be better suited for performance evaluation SPS and review of its design. This paper...
In this paper, a phase balancing algorithm is developed for secondary distribution network by rephasing the consumer service laterals. The algorithm is proposed for rephasing of three and single phase consumer service laterals (service wire connecting home and supply line) at each node from tail end of the feeder. Formulation of algorithm includes average load per phase and average load per service...
Medical data are crucial for providing reliable mobile health services. However, its reliability may be degraded due to internal factors related to performance variations of mobile technologies used in the application and other external ones such as the environmental ones. This paper addresses this problem by proposing an ontology-based approach to deal with data and reliability management in mobile...

The presentation will also demonstrate how using architecture developed for Automotive Safety Integrity Level (ASIL) can help improve the functional...
This paper presents the IHPNode platform in the context of precision farming (or Agriculture 4.0). This platform is an experimental platform for wireless sensor network (WSN) applications and can be used in precision farming as one of the most promising WSN application areas. The paper presents the requirements of the applications, the features of the IHPNode platform, as well as, the planned future...
Given that dynamically variability and uncertainty (randomness, fuzziness, grayness and unsacertainty) exist in comprehensive evaluation of power quality, this paper described and treated the uncertainty information reasonably in index parameter, boundary and weight. Based on the variable fuzzy sets evaluation method, blind number theory was introduced into power quality evaluation to deal with the...
The demand for wireless sensor networks (WSNs) applied to industrial process monitoring and control should increase as the forth industrial revolution gathers pace. Flexibility and low cost make them the perfect choice for the modern 21st century manufacturing plants. In this paper we describe the tests done with a WSN in an industrial environment and analyze the results to ascertain how much interference...
