Autonomous swarm control, which is expected to be able to handle multiple unmanned vehicles (UxVs), is an important technology that can be applied to many operations and incorporated in many systems. For operations in real environments, we have to consider severe conditions under which communications between UxVs may be inadequate and the environment changes unexpectedly. In addition to optimality,...
This work proposes an analytical method for calculating sensitivity index. The proposed method is based on one-at-a-time measurements and calculates the difference between output values and the base solution to define the impact caused by each parameter in the system. The results indicated that the analytical method provides adequate values for the sensitivity index even when the parameters have minor...
Due to the inverter used, DG can not only integrate the active power into power grid but also support the grid with reactive power. This paper proposes an optimal configuration methodology of renewable DG so as to maximize the penetration level of DG considering the temporal characteristics of active-reactive power (P-Q). Further, the uncertainty output of the wind generator, photovoltaic and small...
This paper, considering the complexity of university internal governance effect and particularity of the university itself, aims to build a indicator system to evaluate university internal governance effect, using the Grey Multilayer Comprehensive Assessment Method to evaluate this indicator system, whilst applying the Analytical Hierarchical Process (AHP) and Entropy Evaluation Method to define the...
This article provides an overview of modern methods and approaches to scientific and technological solutions' efficiency assessment. Much attention is paid to the problems of the criteria set formulation and the identification of their optimal structure for solving the stated problem. In the paper, based on practical results, the analysis of the effectiveness of scientific and technical solutions,...
The paper presents a probabilistic approach (PA) to quantify the impacts of increased PV connections in bidirectional feeders within a distribution network. The aim is to establish a tool that can serve distribution network operators (DNOs) in seizing the maximum allowable photovoltaic (PV) connections, and ultimately with their responsibility on providing a reliable and secure power. An uncertainty...
In this paper, we propose a new contextual bandit problem with two objectives, where one of the objectives dominates the other objective. Unlike single-objective bandit problems in which the learner obtains a random scalar reward for each arm it selects, in the proposed problem, the learner obtains a random reward vector, where each component of the reward vector corresponds to one of the objectives...
Based on the three-terminal interval number and the project risk theory, this paper discusses the problem of risk weighting in uncertain market decision-making, and puts forward the method of combining the grey system theory and the three-terminal interval number to determine the weight of decision-making. The best-selling weight, the unsalable weight and the normal weight are calculated by expert...
In the context of flipped classrooms, the evaluation of college curriculum's teaching effect has been a hotspot in current education field. Aiming at the course characteristics of film reviews offered in Huangshan University, the paper establishes an evaluation index system from the angle of teaching output, and conducts an evaluation using grey cluster model. The results show that with the influence...
The purpose of the present study is to empirically investigate whether national culture has an impact on cybersecurity development. We used methods of correlation and hierarchical regression to analyse two sets of indices; the global cybersecurity index of 2015 and Hofstede cultural dimension index. The research discovered that there exist a significant correlation between cybersecurity development...
In this article, after introducing fuzzy-dual numbers, functions and functionals, the optimization of a fuzy-dual functional is considered through an extension of Euler's condition. Then, once uncertainty is imbedded in a fuzzy-dual dynamical system, the optimization of such systems is considered, leading to an extended Hamilton-Jacobi-Bellman equation to characterize optimal fuzzy-dual solutions.
In the government agencies, civil servants are required to have competence or ability to finish the work effectively and efficiently. In fact, the decision-making system for determining position and assignment of civil servants' functional works is still performed manually, so it takes a longer time. Moreover, the results are not totally accurate in terms of their competency. Rough set, hereinafter...
The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor was on board the Suomi National Polar-Orbiting Partnership (S-NPP) launched on 28 October 2011. The VIIRS includes a day-night band (DNB), which is panchromatic with the wavelengths from 500 nm to 900 nm. Its dynamic range covers from full sunlit scenes to lunar-illuminated images. With successful calibration after launch, DNB on-orbit performance...
In the view of the shortcomings of the cloud gravity center and comprehensive cloud evaluation approaches based on cloud theory, the study was carried out combined with the quality evaluation of navy vessel's development alternatives. The basic principles and steps of cloud gravity center and comprehensive cloud evaluation approaches were summarized. According to the measurement requirements of navy...
In the eutrophication evaluation, the uncertainty of evaluation level is the main problem. This process also refers to many factors which have different effect on result. Multi-dimensional normal cloud is a system model which can describe the uncertainty and fuzzy feature. This model involves the factor weight. In our paper, the weight is determined by AHP, CRITIC and information entropy which are...
This paper focuses on the H−/H∞ fault detection observer design issue in the finite frequency domain for a class of uncertain descriptor systems. To detect faults effectively for systems with model uncertainties and in the presence of unknown disturbances, a new fault detection filter is designed to satisfy a finite frequency H−/H∞ performance index simultaneously. First, two basic performance analysis...
The study aims to measure Bina Nusantara University students? perception towards cultural value. Dimensions of gauged cultural value consisted of five indicators, namely power distance, uncertainty avoidance, individualism vs. collectivity, masculinity vs. femininity, and long-term orientation vs. short-term orientation. The study oriented to provide input for the organization upon the perception...
Dempster-Shafer theory of evidence is widely applied to uncertainty modelling and knowledge reasoning because of its advantages in dealing with uncertain information. But some conditions or requirements, such as exclusiveness hypothesis and completeness constraint, limit the development and application of that theory to a large extend. To overcome the shortcomings and enhance its capability of representing...
This paper questions the sizing standardization of small scale energy storage systems in a context of high penetration of renewable energies and non-deterministic load within the power grid. The future electrical grid is more precarious than the classic one by many reasons, inter alia, abrupt meteorological variations are hard to predict. Therefore, the geographic expansion beside high penetration...
This paper presents a novel framework for assessing the physical consistency between two terrestrial Essential Climate Variables (ECVs) products retrieved from Earth Observation at global scale. The proposed methodology assesses the level of temporal and spatial agreement between them using multitemporal data. This is based on the analysis of their temporal changes taking into account their associated...
