Time series modelling has long been used to make forecast in different industries with a variety of statistical models currently available. Methods for analyzing changing patterns of stock prices have always been based on fixed time series. Considering that these methods have ignored some crucial factors in stock prices, we use ARIMA model to predict stock prices given the stock-trading volume and...
The advancement of the Internet of Things and wireless sensors has paved the way for the development of new services for next-generation healthcare systems to enable superior communication between healthcare professionals. This paper presents key components of the Wiki-Health Analysis Framework, which enables an ecosystem to support scientists, developers, and professionals to publish their data analysis...
Recent developments of modern technologies such as cloud computing, wearable sensor devices and big data have significantly impacted people's daily lives, and offer real potential for an Internet-wide, people-centric ecosystem. These advances in technology will considerably extend human capabilities in acquiring, consuming and sharing personal health information. A future in which we are all equipped...
In recent years, constructing regulatory networks using gene expression data has received extensive attentions. From Boolean network, Bayesian network to Module network, a number of models have been applied in order to learn the regulatory networks more accurately. The statistical power of network modeling is directly affected by sample size of available expression data used as training data. However,...
Optimal configuration of energy storage type and capacity is a difficult problem of planning and designing of Energy Storage System which is constructed for distributed generation. To solve the problem, we develop the software PDESS. The functions of PDESS include data analysis, capacity optimization, structure design and scheme evaluation. Considering the system's economy and technical capabilities,...
Batch experiments were carried out to determine the capacity of Pseudomonas fluorescens biomass to adsorb Sr(II) ions from aqueous solution with respect to pH, initial Sr(II) concentration, contact time and biomass dose. The FTIR results of Pseudomonas fluorescens biomass showed that biomass has different functional groups and these functional groups are able to react with metal ion in aqueous solution...
In the study of complex networks, weighted networks have been applied to various fields, as such mediums can provide more realistic and comprehensive description of reality. In this paper we study BBV (Barthelemy and Vespignani) weighted model as well as its dynamic properties of complex networks, which could play an important role both in theory and practical applications. Through comprehensively...
Assessing and understanding the level of city ecological security are of great importance to sustainable urban development. According to the pressure-state-response model, the indexes of city ecology security assessment were chosen. Subsequently, the assessment model based on projection pursuit technology was set up and used for a case of Hefei city. The result shows that the ecological security level...
Microgrid technology, becoming the main application form of distributed generation with high permeability, can effectively alleviate the impacts on large power grid of distributed generation. Microgrid system, as the carrier of microgrid control strategy, can provide verification platform for the research of microgrid control strategy. In this paper, an integrated microgrid system with flexible structure...
The current economic architecture of the Internet resembles more an Oligopoly-with several very large organisations dominating-than the idealised free market that many thought the Internet's characteristics-high non-local connectivity and low technical barriers to entry would enable. Internet-based individual and SME entrepreneur ship, as well as peer-to-peer markets, remain a poorly supported and...
The usage of economics in grid systems designs has been very popular recently and a large number of system designers have attempted to use economic concepts to engineer the grid market mechanism that would enable an efficient allocation of resources. However, only few of these designs have been actually implemented and, in fact, very few, if any, have been successfully adopted by end users. The argument...
This paper studies the realizing progress of data mining in psychological evaluation. Based on the matrix of evaluation data and the actual evaluation work, we propose a kind of generalized linear regression model with convex constraint, named as evaluation model, in which the dependent variable and regression coefficients all are unknown. We analyze the algorithm of the model with linear regression...
There's been some misunderstanding toward the experience concept. The paper analyzes and hackles experience from many aspects such as psychology, philosophy, economics and management science. After that, a customer experience hierarchy model, which includes experience effects, experience themes and experience attributes, is brought forward based on the theory of customer value hierarchy. This model...
In this paper, based on the analyzing the signal control problem of single intersections, a kind of real-time optimization method with PSO (particle swarm optimization) solving signal timings for single intersection is put forward. On detecting the flow of current cycle and the cycle before, estimating the flow of next circle is proceeded. Setting least delay as performance index, we get each phase...
