Relating the microscopic parameters to the macroscopic characteristics of traffic flow by mechanism deduction can make the calibration of the microscopic parameters conveniently and efficiently. The corresponding researches of the steady state flow have been reported in the literature. However, as the steady states are easy to be broken by disturbances and other factors, the actual traffic flow is...
Industrial analysis & forecasting system (IAFS) simulates and forecasts industrial macroeconomic cycle trend by analyzing the industrial data using various models. Currently, as a system, which should integrate multi-model and multi-data-source, IAFS has two bottlenecks in its development and application, i.e. models' update, reuse and system integration, and data update and integration. This...
Automatic conveying system was used widely in Distribution Center. The paper discusses the high-fidelity simulation methods on Automatic conveying system, analyzed automatic conveying system high-fidelity simulation levels of classification, reference standards and key points. An evaluation for simulation value and cost of each model is implemented. A high fidelity Simulation Modeling of a cold DC...
Caster vibration waveform with variable, non-sinusoidal vibration characteristics, the device uses electro-hydraulic servo drive control algorithm using variable universe fuzzy control, robustness, high control precision, fast response. The paper focuses on variable universe fuzzy controller of rigor the flex-factors that ensure its applicability, and integration testing to determine model parameters,...
Flood disaster management is an important part of flood risk assessment. A regional flood disaster risk assessment index system is established in this paper. Then principal component analysis (PCA) method and BP neural network are combined, and a regional flood disaster risk assessment of PCA-BP neural network model is established. PCA-BP neural network model analyze the loss of flood disaster about...
Supply chain cooperation partner selection plays a significant role in supply chain research. In order to solve the adverse selection during selecting supply chain cooperation partner, the screening model is come up under some particular hypotheses. This paper analyses the optimum solution of the model in all cases, and designs contracts on the basis of optimum solution. Under certain conditions,...
As the increase in service level, there is necessary for D University to introduce advance management theory to improve service level. In this paper, the writer point out the problem of D University Financial Department, and use Queuing Theory and Pooling Theory to improve the service level of Financial Department of D University.
Abstract-The enterprise culture measurement is the core of the enterprise culture management. Because of the regional culture diversity, there are abuses when we use the foreign culture measurement form directly to study on our country's enterprise culture in practice. This article based on the OCQ scale and OCAI scale. Through adjusting preparation and modification of the enterprise culture, we can...
Encapsulated invoking structural analysis can be carried out by using VB to realize the secondary development of ANSYS. Firstly, the parametric command flow file of the problem to be analyzed will be compiled, which is based on the exploitation capability of APDL of the finite element analysis software ANSYS. Then, the analysis of the structure will be automatically completed, through a convenient...
Innovation ability is a measure of an important indicator for the national high-tech zone. In this paper, the evaluation index system of innovation was established,12 typical samples were selected in 56 national high-tech zones used data envelopment analysis. Based on the creative efficiency evaluation system, innovation ability is analyzed and evaluated by C2R model. Using results of the analysis...
The research of corporate governance regards the separation of ownership and control as a basic proposition. Accordingly, the core issue of corporate governance becomes the conflict of interests between stakeholders. Shareholding structure is an important factor in corporate governance structure, and the transformation of different shareholding structures constantly harms or protects the interests...
In the research of pile's lateral capacity, the effects of pile cap are usually neglected to make the problem simplified. Site tests demand a lot of time and money, a few data published can be obtained, even few the test of pile with cap, so it's hard to figure out the effect of cap on the lateral capacity of single pile. By using ABAQUS finite element software, three dimensional numerical simulation...
Abstract- To reduce the construction complexity of multi-agent system, the proposal is presented that combining several small systems into a larger one, and obtain the properties of the larger system through the properties of small systems. Make reference to dynamic task allocation based on contact protocol, the macroscopical model for task allocation and the microscopical model for agent inner BDI...
Nowadays the research method of financial crisis early-warning models is linear, in which there are some faults, such as imperfect crisis theory and basic hypotheses, lacking critical variables and confusing the targets. These issues seriously affect the models predictable efficiency. In order to improve the financial crisis warning-models, we should enforce the research of basic financial crisis...
In this work, a deep submicron double-gate (DG) Gallium Nitride (GaN)-MESFET design and its 2-D threshold analytical model have been proposed and expected to suppress the short-channel-effects for deep submicron GaN-MESFET-based low power applications. The model predicts that the threshold voltage is greatly improved in comparison with the conventional Single-Gate GaN-MESFET. The developed approaches...
In this paper, we presented a new analytical model for the transconductance and output conductance of submicron gate-length GaAs MESFET transistors. After an analytical study of the current voltage characteristics, the transconductance and drain conductance mathematical expressions are determined as a function of the drain and gate voltages in different operations regimes (linear, non-linear and saturated)...
An algorithm for multiparameter sensitivity analysis of a synthesized network based on a nullor model of active devices is implemented. It is simplified by using the modified Coates flow-graph. Due to the suggested method, additional information for parameter influence upon transmission coefficients in the circuit is obtained, all partial transfer functions and their products can be found. An example...
The constraints to manage in a telecom splitter design are numerous and according to a given splitter structure, the choice became difficult. The paper proposes a software tool allowing the design of such filters. This one carries out the modelling of the electrical circuit configurations, and creates the corresponding computation code, used for simulation or optimisation. The methodology is detailed...
State charts is widely used as a behavioral modeling language for reactive systems for its concise and intuitive expression, especially a few high security system. However, the lack of formal semantics makes it difficult to analyze and validate the system which it described. The paper proposed a formalization method based on temporal description logic. Firstly, temporal description logic (TDLs) is...
