In the article, the plans of acceptance sampling for log-EIG distribution are established while the lifetime test is truncated at the pre-assigned time. The smallest size of sample to guarantee the provided median lifetime, the operating characteristic functional value of the plans and the risk of the producer are given. An algorithm is offered for building the plans. The outcomes are illustrated...
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...
This paper presents the statistical analysis of Grid events in the Western Regional Power System of India. The major findings and recommendations derived out of the analysis provided vital inputs for prioritizing the measures to be taken for improving compliance to technical standards, improving the operation and maintenance practices, planning for equipment upgrades and ultimately in enhancing the...
In this paper, we develop a new transitive aligned Weisfeiler-Lehman subtree kernel. This kernel not only overcomes the shortcoming of ignoring correspondence information between isomorphic substructures that arises in existing R-convolution kernels, but also guarantees the transitivity between the correspondence information that is not available for existing matching kernels. Our kernel outperforms...
We introduce a powerful technique to make classifiers more reliable and versatile. Background Check equips classifiers with the ability to assess the difference of unlabelled test data from the training data. In particular, Background Check gives classifiers the capability to (i) perform cautious classification with a reject option, (ii) identify outliers, and (iii) better assess the confidence in...
Implementation of Smart Grid into the power system has made our grid more robust and reliable. Due to integration of two-way, real time communication it is possible to monitor equipment through sensors. Continuous monitoring will help to predict the state of the equipment. Due to this fact and also to ensure the system performance, time based maintenance can be replaced by condition or reliability...
Typing is a well known concept to prepare services for data processing for instance by choosing the correct service to a mime type for processing. But a lot more metadata elements, like availability and access conditions, provenance, processing preconditions or integrity parameters, are useful to be known in advance for preprocessing data services. In order to expose such metadata independently from...
Schizophrenia is a severe psychiatry disorder characterized by the positive and negative syndrome. Previous studies often treat the two syndromes independently. In our study, we proposed a multi-task regression and stability selection combined method to explore whether the two syndromes shared same brain functional deficits. 35 drug-naïve adolescent participants with first-episode schizophrenia were...
A course is defined in terms of its course outcomes, which are statements on what the students should be able to do at the end of the course. Assessment instrument(s) should be designed in a way to measure students' mastery of these course outcomes. Item bank is a collection of assessment items from which specific assessment instruments can be created. Quality of an assessment instrument is ensured...
In SDP-based H∞ control, we often encounter numerical difficulties when solving SDPs by various pieces of software. It is empirically known that such numerical difficulty occurs if an SDP at hand or its dual has no interior point feasible solutions, and this is indeed the case of some SDPs in H∞ control. To conceive a way for getting around such numerical difficulties in a concrete problem setting,...
The assessment of travel time reliability for segments and routes is a rapidly advancing frontier. The increasing availability of probe data is making it possible to monitor reliability in real-time based on individual vehicle data as opposed to ex-post-facto based on averages. This paper examines metrics that can be used to monitor reliability based on probe data. The merits of traditional metrics...
This paper presents a probabilistic methodology applied to FPGAs (Field Programmable Gate Arrays) logical structures known as basic building blocks, namely: CLBs (Complex Logic Blocks), usually consisting of LUTs (Look-up Tables) and biestables (flip-flops), PSWs (Programmable Switch Matrixes), IOBs (Input-Output Blocks), SMRAs (Static Random Access Memories) and CBs (Connection blocks). The scope...
Communication becomes core and one of the most important roles in many business practices, indeed audit as a service product is no exception to communication needs. This research is conducted to examine whether auditor's ability and willingness to communicate with client and professionalism in work as variable independent have significant impact on client responses in collaborating and supporting...
Performing statistical inference on massive data sets may not be computationally feasible using the conventional statistical inference methodology. In particular, there is a need for methods that are scalable to large volume and variability of data. Moreover, veracity of the inference is crucial. Hence, there is a need to produce quantitative information on the statistical correctness of parameter...
In order to evaluate the performance of smart electricity meter (SEM), this paper studies the reliability of the SEM. We introduce the indication of the reliability and analyze the standards and documents relevant to SEM. Then, we use the component stress method to predict the reliability of SEM based on the study of SEM. Finally, through an example, we obtain the expected failure rate of SEM from...
The notion of subjective image quality (SIQ) is particularly difficult to define as it depends on a large variety of physical attributes and psycho-physical factors. One important attribute which SIQ depends on is the illumination under which visual stimuli are observed. Recent studies have shown that achromatic fidelity (i.e. perceived resemblance in lightness) is significantly less dependent on...
Information and Communication Technology (ICT) has changed the world scenario including business and economies. There are new opportunities and challenges for every country to produce knowledge oriented citizens. Driven by these changes, numerous higher education institutions around the world are integrating and adopting latest ICT tools to deliver quality education. However, the Effectiveness of...
some urban corridors see serious congestion during rush hours, but travel time is still predictable; while others may not suffer from heavy congestion but exhibit high travel time unreliability. The latter case usually makes motorists more frustrated. Moreover, empirical studies show that the level of unreliability varies over time of day. Using the collected travel time and travel speed data, this...
There are several standardized protocols based on SpaceWire which provide data exchange between several nodes. SpaceWire is also suitable for interprocess communication (IPC), by the help of higher level protocols. However, currently there is no standardized protocol which is targeting IPC on SpaceWire networks. This paper proposes a protocol, which uses the capabilities of SpaceWire to build up networks...
SpaceWire is a new bussing technology provided by European Space Agency. SpaceWire enhances the functions of error detection and error recovery [1]. Considering the application background, the reliability of SpaceWire network must be guaranteed. The paper develops a new hot back-up method for improving the reliability of SpaceWire network. The method uses the one of the reserved bits of time-code...
