The study of genealogy is an increasingly popular activity pursued by millions of people, ranging from hobbyists to professional researchers. Such genealogical datasets provide a great opportunity for social science analysts, historians, and the public to study a wide variety of topics in demography, family and household, kinship, stratification, and health. Nevertheless, the large scale and characteristics...
To identify the performances of an aeration equipment, it is necessary to determine some parameters which helps to classify it from the hydraulic-technical-economic point of view. Current methods compare mechanical equipment to hydrodynamic parameters. The most important parameters are the oxygenation capacity, CO [kgO2/h], the economic coefficient, E [kgO2/kWh] and the specific power index, δ [W/m...
This study, part of an ongoing global study, aims to advance information society research and practice by examining and understanding the information and communication technologies (ICT) adoption in enterprises in the context of the sustainable information society (SIS). In this study, the ICT adoption is described by four components. i.e. outlay on ICT, information culture, ICT management, and ICT...
The task of minimizing the costs of providing IT services, as a task of optimizing control actions on quality indicators, was solved. An Statistical Aggregation and Decomposition approach was developed to study the quality of IT services on the basis of multiple regression and autoregression of the integrated moving average, in which these methods were jointly used to predict the components of the...
To date, the basis of eigenvector spatial filtering is solely the centered spatial weights matrix (SWM) that is part of the Moran Coefficient (MC). The Laplacian matrix, < CI >diag-C offers an alternative transformation of the SWM, one associated with the Geary Ratio (GR), another popular measure of spatial autocorrelation (SA). This paper compares these two specifications, respectively denoted...
Based on economic development and resource of Countries of “the Belt and Road”, the paper divides OFDI into two types by clustering analysis which are Resource Acquisition OFDI and Market Acquisition OFDI, and uses the method of Grey Incidence Analysis to conduct an empirical research on location choice determinants of OFDI from China to Major Countries of “B&R”. It shows that market size, political...
Chinese coastal provinces are suffering from storm surge, which causes huge economic losses, since several years. The purpose of this paper is to calculate the grey correlation degree according to the similarity in the change rate of direct economic losses between different provinces with GCRA model and cluster the coastal provinces. This paper selects the most typical five coastal provinces, using...
Research shows that public events can be violence attractors or generators. Recent studies focus on the effect of crowd events on spatial crime analysis, using environmental criminology theories as a background. Also, social media analyses show possible influences of social media in crowd movements. This study displays and correlates spatial patterns of crimes and tweets around two stadiums in Manchester,...
The aims of this study were to forecast change of Chinese social donation in recent years by grey Verhulst model to find out characteristics of social donation and grey correlation analysis which was proposed by Professor Deng Julong is used to detect of an interpersonal relationship between the number of social donations from oversea and the number of foundations. This paper provides a quantitative...
Existing research on layout of the marine industry is still at a scattered exploration stage, and results calculated with a relatively mature grey correlation method indicate that China is divided into three major industrial correlation regions with Shandong, Shanghai and Hainan as the core respectively while marine departments are still lack of correlation among them. According to calculation results...
Foundation Management Regulation has promulgated since 2004. University education foundations have sprung up, especially among the 985 and 211 key universities The Ministry of Finance and the Ministry of Education have implemented donation matching policy towards subordinate universities since 2009, leading to a rapid growth of donated funds. The university education fund starts to put attention on...
Learning evaluation in larger online university courses has become a challenge, especially in those cases when learning focuses on the development of professional skills. The objective of this article is to analyze how "authentic Assessment" applied by students correlate with the judgment of the teaching team, in the framework of a course for business and administration students. The results...
The multi-homing technique in the dynamic spectrum access networks presents the key mechanism to improve the overall spectrum utilization and social surplus of the end-users willing to communicate. In general, multi-homing allows the enduser to switch dynamically among the operators and together with other bunch of protocols are being developed in the IETF. They aim for better utilizing the network...
Recommendation system becomes popular in recent years, because it provides more information about products which consumers are more likely to be interested in. However, bundling module, as one way of recommendations, does not appear on any product's page. In this paper, we will explore the impact of product characteristics on the bundling strategy implemented by recommendation system. We found that...
The paper analyses historical cross border commercial flow (CBCF) of electricity for Germany for the years 2012 to 2015. Based on graphical solution for CBCF it is hypothesized that with increasing shares of fluctuating renewable energy sources in Germany, it would be exporting more electricity at lower prices while importing at relatively higher prices. For this the relation between CBCF, spot prices...
This paper analyses how strongly EU energy policies have driven electricity wholesale prices. Especially, it investigates whether the activities of the Energy Union directed to increasing competition in the electricity system, creating an internal market without barriers for electricity flows, supplying sustainable and secure electricity, has led to a decline in electricity prices. Therefore, renewable...
Commercial seaports are a key component in the transport chain and particularly in the supply chain and in the production process. Port performance is a recurring question as each change in ports affects their performance level. These changes occur at different levels: international (technological advances), national (division of traffic between different regions) and local (land use planning). This...
Aiming at the problem of expert weighting in group decision making, an expert weighting method based on D-S evidence theory is studied. Three ways such as the distance, grey correlation and the combination of these two methods are used to measure the deviation degree of the experts' opinions on the scheme, construct mass function based on this, and uses the D-S synthesis rule to carry on the information...
The multitude of events that rapidly take place on the political scene of the whole world have fundamental economic consequences in the development of all countries. Our study combines financial elements which may influence the economic relations that currently exist between the countries of the world and the ones belonging to the European Union in particular. The processing of the high quantity of...
