In this paper, we clearly study the properties of the Hermite positive definite solutions of a nonlinear matrix equation and improve a result. We get that if a condition is satisfied, all eigenvalues of the Hermite positive definite solutions of the equation locate in a range.
Many networks in real life such as electric power systems, transportation systems and manufacturing systems can be modeled as a stochastic-flow networks whose arcs and nodes have discrete and multi-valued random capacities. For such a flow network, the system reliability is the probability that the maximum flow of the network is not less than the given demand d. The researchers in this field have...
The tender offer cost of IT project is the basis of IT project valuation. This paper analyzes the tender offer cost of IT project, as well as the composition of the tender offer cost. The focus of IT project is on the cost of the tender offer, and it includes the cost during IT project's tender offer, the cost of the measures of IT project, the cost of IT project subcontractor, and IT project's imprest...
Target intention inference is an important aspect of situation assessment. The evidence system of targets' intention inference is discussed according to the independent relationship between targets' intention and input evidence. The targets' intention probability inference model is proposed based on static Bayesian network. In order to expand the application domain and predigest the parameter learning...
The poor operation ability is one of the main reasons for the difficult employment of college graduates. In order to solve this problem, considering professional characteristics of automatization, research and improve four training methods of single chip microcontroller course like the theory teaching, laboratory teaching, curriculum design, and examination. And get rid of the shackles of the old...
Hybrid Electric Vehicles (HEV) offer the ability to significantly reduce fuel consumptions and emission. Management of energy is one of essential elements in the implementation of hybrid electric vehicles. Engine and motor should satisfy the driver's demand in different driving environment. This paper defines a driving cycle sensitivity parameter, which is used to create different driving cycles to...
Hybrid electric vehicles (HEV) is becoming the important develop tendency of the vehicle for its better fuel economy and emission. The parameters of HEV control strategy is always optimized on some one standardized driving cycle, but the different city have its own driving cycle. So the great advantage of HEV is limited. This paper proposes an intelligent management for parallel HEV based on driving...
In this paper, the uniqueness of the weak solutions of the three-dimensional infiltration problem is proved with reduction to absurdity by constructed a special text function.
Product semantics is a tool in product design to generate newer, better and more meaningful forms. Consumer preference and perception of products strongly influence a product's acceptability. Both are expressed by words that may be studied using product semantics. As product semantics spreads rapidly in product design, it faces more interrogative challenges from the lack of empirical evidence to substantiate...
The product innovative design comprehensively reflects the economy, technology and culture of certain times. On the basis of studying the elements of technology, culture and population of the product design process and the analysis of the existing rules and inter-links of the three elements, concrete methods and strategies of the enterprise product innovative design are given, which provide the basis...
The new technology in the design of a clutch product is presented in the paper. Its principle is to realize the separation and reunion of movement between the driving part and the driven part by controlling the rotary fit and separation of the screw thread pair. The relative axial movement in the rotary fit of the screw thread pair is used to control the auxiliary friction driving, establish the pre-starting...
Sustainability is the only rule of human future survival and development. By analyzing the internal relations of universal design, green design, barrier-free design etc, this paper presents sustainable factors included in the concept of universal design. It points potential direction for the perfect development of universal design in the contemporary background.
The number of software deployed on mobile terminals is dramatically increasing. However, this leads the mobile terminal facing a serious of security threats. In order to resolve these threat issues, several security requirements are proposed. Also, this paper introduces a secure software download framework and corresponding download protocol based on mobile trusted computing, designed to handle a...
The tapered narrow side waveguide is applied into the waveguide-to-coaxial transition to obtain a wider band. The simulated results testify that this structure is useful to make good impedance matching.
A new type of six-axis full shearing strain force sensor has been developed. It uses strain gauge as sensing element for the detection of force. The elastic body is a thin cylinder on which four holes are opened evenly in two levels. There are six Wheatstone bridges on the beams to detect the force in six directions. The sensor was designed from the results of finite element method (FEM) simulation...
In this paper, a color gamut transformation method which transformed the different color gamut into a same one has been proposed. In the transforming process, the deviation which was arose from the quantization error and the truncation error were existing. If the deviation was out of the color tolerance, the uniformity of the screen color will be deteriorated. Firstly, the color tolerance of vision...
Hybrid Electric Vehicles (HEV) is becoming the important develop tendency of the vehicle for its better fuel economy and emission. And design and implementation of Energy Control Strategy become one of the most important problems of the HEV. A fuzzy control hybrid electric vehicle model is created using CRUISE and MATLAB in this paper. For improving the fuel consumption and reducing emissions, the...
Focusing on whether ldquoThrough train of Hong Kong stockrdquo has a significant impact on return and volatility spillover relationship between Hong Kong, Shanghai and Shenzhen stock market, this paper applies the VAR and Multiple GARCH model to the research based on the three stock markets data. The evidence shows that no return spillover effect exits between Hong Kong stock market and Shanghai or...
Split-share structure reform has been a focus since its implementation. It is of great significance in theory and practice to solve whether the circulation initiatives of 2/3 of the non-outstanding shares for listing companies are promoting the development of capital markets validity. By sampling A-share listed before December 31, 1996 in Shanghai stock market, this paper analyzes the simulation of...
The different regions have different characters in the foreign capital utilization of forestry. The paper divides the country into five forestry economic regions, and analyzes the scale and industry direction of forestry foreign capital of each region. In order to find out the weaknesses of each region, the representative provinces of each region are chosen, that is Heilongjiang Province, Henan Province,...
