The statistics of extreme wave heights is of great importance in many ocean and coastal engineering applications and is an important part of physical oceanography. For example, in the design and operation of marine structures one needs to take the influence of extreme ocean environments into account and estimates of very large return values of wave heights are often needed. However, due to the limited...
In this paper, we describe the LFM-1b User Genre Profile dataset. It provides detailed information on musical genre preferences for more than 120,000 listeners and links to the LFM-1b dataset. We created the dataset by exploiting social tags, indexing them using two genre term sets, and aggregating the resulting annotated listening events on the user level. We foresee several applications of the dataset...
Linear-quadratic problem for a time-invariant scalar continuous time system and a bound spectrum disturbance is considered. The problem is shown to be degenerate; and an algorithm of the regulator synthesis is presented.
Supplying electrical energy to the load on demand, economically and with acceptable levels of reliability and service quality is the main task of a distribution system. Energy distribution reliability is important in the competition conditions in electricity markets because consumers directly supply energy. Therefore, it is not enough to estimate how reliable the distribution system is at present...
A novel procedure to validate the existence of clusters of the Malaysian lady foot shape measurement is proposed in this study. The Cophenetic Correlation Coefficient (CPCC) index is used to determine the optimal linkage method and distance measure. Mixture distribution confirmed the number of clusters. Three foot shape features that are Left Foot Length (LFL), Left Foot Breadth (LFB) and Left Ball...
To try to decrease the preference of the attribute values for information gain and information gain ratio, in the paper, the authors puts forward a improved algorithm of C4.5 decision tree on the selection classification attribute. The basic thought of the algorithm is as follows: Firstly, computing the information gain of selection classification attribute, and then get an attribute of the information...
Smart city or urban wisdom is the new goal of urban development. In view of how to develop the wisdom city better, this paper analyzes the present situation of wisdom city development in China, and uses the entropy weight method to construct a new intelligent city evaluation system with reference to the existing wisdom city evaluation scheme. According to the data of Beijing, Tianjin and Shanghai,...
In the face of energy crisis and environmental pollution problems, all the countries in the world vigorously promote the development of electric vehicles. Electric vehicle charging infrastructure is the necessary infrastructure to the development of electric vehicles. This work has been focused on Electric Vehicles' Charging Stations (CSs) deployment. It has been considered in this study several constraints...
Fast, on time and large transport capacity, cleaning and other factors make cities gradually increasing demand for urban rail transit, and demand is growing faster than construction speed, so it is necessary to ensure the transport capacity to improve the operations quality of service. At the same time the discretion of the rail transit quality of service affect the choice of rail transit passenger...
The evaluation of intelligent transformation level of primary equipment in substation is an important part of the second batch of intelligent substation pilot project. In this paper, pilot projects for the transformation of smart substations in several regional power grids are extensively investigated, of which the following work is done on the basis: Firstly, the evaluation model of intelligent transformation...
The naming of local variables is usually at the programmer's discretion. Thus, there is a diversity in naming local variables and this may cause variations in the code quality. Many coding conventions say that the name of a local variable can/should be short. This paper focuses on such conventions, and aims to explore the trends of local variables' names in Java and examine if abnormal local variables...
In many manufacturing application the system reliability performance is a key issue in order to obtain the best performance of the equipment. The paper focuses on the reliability enhancement of complex systems containing redundant architecture using the Reliability Importance (RI) methods in order to evaluate the weight of each element on the whole system reliability. The first part of the paper is...
Encoding spatio-temporally varying textures is challenging for standardised video encoders, with significantly more bits required for textured blocks compared to non-textured blocks. It is therefore beneficial to understand video textures in terms of both their spatio-temporal characteristics and their encoding statistics in order to optimize coding modes and performance. To this end, we examine the...
Software Defined Networking (SDN) enables a centralised entity - the controller - to monitor the network’s status by collecting traffic statistics such as packets, bytes, etc. Each statistic is associated with a forwarding table entry (FTE) in a switch whose structure and format is specified by the OpenFlow standard (de-facto SDN standard). For a flow with a FTE, its statistic is easily...
This paper introduces compact music-inspired computing. We propose a music-inspired optimization technique with minimal computational cost. The aim is to reduce the memory storage capacity required by the classical harmony search algorithm (HSA) while improving their performance. Therefore, we propose three compact harmony search algorithms. The main idea is to represent the harmonies stored in the...
We propose a new algorithm for portfolio optimization based on statistical arbitrage, that uses a multi-criteria decision making approach to obtain the most preferred assets. A preference flow graph of financial assets is constructed at each time step, with the aid of statistical arbitrage algorithm that describes preferences among the assets. Then, the individual preferences for each asset are obtained...
The relevance of the formation of the national digital economy is confirmed by the presence of global trends of digitalization of the international society and the need to preserve digital sovereignty of Russia. The article analyzes the subindexes of the international Networked Readiness Index (NRI) and identifies the factors that have affected Russia's lag in the network readiness rating in order...
To solve the complexity and difficulty of tree species selection of wavebreak forest in a certain area effectively, an improved fuzzy optimum selection model (FOSM) using the tree species suitability multi-index system is proposed for wavebreak forest in flood control planning. And a new relative membership degree formula is introduced in the FOSM. Through the improved FOSM, the tree species recommended...
This paper is concerned with a kind of non-zero sum differential game of mean-field backward stochastic differential equation (MF-BSDE). A necessary condition for Nash equilibrium point is derived first, then the result is applied to study a linear-quadratic (LQ) game. The explicit form of candidate Nash equilibrium point is obtained.
The intelligent evaluation of substation primary equipment is an important problem in the construction of smart grid. Based on the actual project data, the following work has been done in this paper: The evaluation model of intelligent level of primary equipment in substation is established; the concept of correlation coefficient is put forward by combining AHP (Analytic Hierarchy Process) and entropy...
