Using a characteristic function method the mixing property and ergodicity of strictly stationary continuous-time linear random process driven by process with independent increments have been proven.
The control of a modeled new concept gearless Orbital Infinitely Variable Transmission (OIVT) is presented. The concept and the mathematical model were used in order to apply a PID controller and explore the behavior of the closed loop system. The desired trajectory is needed and implemented in order to achieve the control goal. The results shown good performance in different conditions of load and...
This paper presents the design of a model for simulation of a food extruder. The model has been obtained from the energy mathematical model and experimental data of a real extruder. Some process variables having no relation with the energy model have been added to the model. Experimental results show information about extruder performance when some controlled, manipulates and additional variables...
In this paper we describe a new maximum likelihood approach to infer kinetic rate constants from time-course data and apply it to estimate the rate constants of the synthesis and degradation of the mRNA of Cdc20 protein, and the rate constant of the transcription of the cdc20 gene into Cdc20 protein. The Cdc20 protein plays a crucial role in eukaryotic cell cycle, as it codes for the cyclin antagonist...
In this paper, a special class of differential systems, which is known as linear, time invariant (LTI) descriptor (regular) differential systems with multi delays, is analytically studied. These kinds of systems are inherent in many physical, financial, and engineering applications. Using some elements of matrix pencil theory, we decompose the main system into two subsystems, whose solutions are obtained...
In this work, a fault detection method based on a neural-network models bank to residual generation and a residual evaluation scheme using a fuzzy rules type is developed. The case of study is a nonlinear hydraulic system consisting of two interconnected tanks which is simulated, in normal conditions and fault conditions. In this case we use also its equivalent Takagi-Sugeno Model in discreet time...
In this paper, a forecasting method, combining grey model (GM) with partial least squares regression (PLS), was applied to forecasting city terminal energy consumption for the first time. PLS is of the advantage of overcoming the correlative affect among independent variables, distinguishing the system signal from noises, and explaining dependent variables well; GM (1, 1) model is able to overcome...
An autoregressive integrated moving average (ARIMA) model was one of the most popular linear models in financial time series forecasting in the past. In this context, a time series analysis of the NASDAQ composite indices is provided study its movement in 1998-2008. This paper proposed a general expression of seasonal ARIMA models with periodicity and provide parameter estimation, diagnostic checking...
Changes in market interest rates led to the changes of bank's assets and liabilities values, which led to the change of the owner's equity of the bank and bring in risk to the bank owners. As a result, interest rate risk management of commercial banks is extremely important. We built a portfolio optimal model for bank assets and liabilities management by controlling the interest risk, which controls...
This paper deals with the collaborative campaign of pair-warships, whose decision-making process is described. Considering behavior and cognition factors of decision-makers, the mathematical model of two-decision-maker decision-making process with superior-subordinate relationship is constructed subsequently. Based on this issue collaborative decision-making consistency and its measurement are defined,...
Automatic understanding of human behavior is an important and challenging objective in several surveillance applications. One of the main problems of this task consists in accurately defining models able to characterize in a discriminative but, at the same time, enough general way people actions. In this work a bio-inspired model is proposed to represent people interactions in a Bayesian framework...
Based on the researches of the perceived risks in the Web, we construct a model to deal with the perception how to influence customers to buy in the field of C2C . Then, get 192 effective questionnaires through Internet survey. It is proved store risk, product risk, and delivery risk are 3 dimensions of C2C consumers' risk perception. The effects of product risk influence consumers' purchasing intention...
The fictitious economy and real economy constitute a new pattern of economic system in the modern society. The theoretical model about interaction development between fictitious economy and real economy is deduced based on the theory of financial development and economic growth, and empirical analysis on the relationship between China's fictitious economy and real economy using 2001 to 2008 monthly...
The strategy of sustainable development is paid more attention by the people in the world. It is urgently to solve such problems by an appropriate method. This article applies ecological footprint to account and analyze the sustainable development of China's Heilongjiang province from 1995 to 2006. The following results were obtained. The arable land contributed most to the ecological footprint among...
The thin coal mining equipment multi-rank choice and it is traditional choice method subjective capriciousness question, This paper is intended to discuss and analyze the assessment of mining method by the utilization fuzzy set and fuzzy mathematic theory, the equipment to carry on the multi-ranks to decompose, carries on the quantification recursive operation according to the normalizing formula,...
The option contract is one of the effective financial instruments for avoiding risk. There always exists the risk in supply chain especially when facing uncertain or random demand. By introducing the real option into a two-stage supply chain, the part of the buyer risk due to demand uncertainty can be shifted to the supplier, and the supplier, in turn, is recovered by the additional revenue obtained...
Since the principal-agent relationship exists between independent directors (IDs) and shareholders, the incentive compatibility problems which are still unsolved should be given more attention. The traditional fixed-pay system could preserve the independence of IDs, however, lack of incentives; the performance-related incentive mechanisms have great impact on IDs' independence which is the core of...
Nowadays, web portals have become a useful way for high-tech information centers providing information services for high-tech enterprises. The importance of evaluating the information service quality of these Web portals has been recognized by both information service researchers and practitioners. By applying an analytic hierarchy process (AHP) approach, a hierarchical structure evaluation criteria...
With the theory support of "the first law of geography" the spatial variance of the land use landscape in Haidian District of Beijing is analyzed with the geostatistic tool and grid sampling method. The spatial organization and mechanism of urbanization can be well understood by the reveal of spatial characteristics of artificial impact and ecological effect. The results show that: (1) the...
The human eye is able to locate objects or regions of importance in its field of vision. Many visual saliency models have been proposed to replicate the human visual system (HVS) in detecting salient objects in a visual scene. A colour space transformation from the RGB space is assumed to increase the detection performance, given the reason that the transformed colour space would allow a better representation...
