Improvements of energy efficiency and reduction of electricity consumption can be promoted by growing knowledge on the determinants of residential electricity consumption level (RECL). Due to numerousness, complexity and multiple correlations among impact factors (IFs) of RECL, feature selection is an essential step to ensure the precision and stability of an explanatory model. However, the current...
PPV (Perturbation Projection Vector) modeling is an unifying theory for the characterization of the general oscillators. However, for the emerging memristor-based oscillators, the existing PPV abstraction method, which is based on the direct PSS/PXF simulation, encounters the convergence problem due to the hidden state. In this paper we propose a reliable PPV abstraction method based on the conversion...
The dynamic Simulation of coal enterprises is proposed with system dynamics. Having been proved effective, Zaozhuang Coal Mining Group is applied as an example to carry out case study on four behavior patterns simulated. The results demonstrate that this model is available and can be implemented to simulate, predict and analysis the future development of coal enterprise ecosystem with sound suggestions.
Because of the inherent complexities and strategic impacts of BOT (build-operate-transfer) projects call for careful concessionaire selection methodologies. Selection of the right concessionaire, which is critical to the success of such BOT projects, depends on the quality of identifying and defining suitable project-specific criteria and the quality of formulating an efficient tender evaluation methodology...
A commercially available seat equipped height and prominence adjustment function was designed and used in the current study. 11 participants completed the experiments. Participants were asked to sit in a set of designed positions or randomly adjusted positions, the positions, and the interface pressures and subjective ratings of these positions were recorded. Four pressure variables were defined and...
As the complexity of grid environment, grid contains a variety of resources. We introduce the economic model in order to respond the changes of resource supply and demand. In this paper, we based on the original economic model and subdivision the role of resource providers, then we formulate an initial pricing strategy of underlying resources which based on Cournot equilibrium theory to achieve maximum...
Resources in grid are distributed, heterogeneous, autonomous and unpredictable. Resource Management (RM) is required to integrate and manage them to provide efficient and reliable services for users. To have an overview of the stat-of-the-art of Grid Resource Management, this paper does a taxonomy and survey of related researches. The context (refers to initial design objectives of Grid in this paper)...
This paper gives a new portfolio optimization model based on dual expected utility. In the model, considering that the transaction number is integer and short sale is not allowed in China's Stock Market at present, we introduce the constraints of minimal transaction unit and upper bound of investing in each asset in the friction market and we regard the utility risk as the risk under the non-conventional...
Taking the road of sustainable agricultural development to ensure food security and agro-ecological security is a severe problem that the world's agricultural development faces and is also the fundamental strategy of China's present and future agricultural development. This paper carries out Game Analysis of farmers and the government during Chinese agricultural sustainable development. The results...
Taking into more account practical situation of Chinese securities market with non-convex non-concave typical transaction cost and revenue and measuring the risk of the securities by the conditional value at risk, we establish a portfolio model in which the expected income of portfolio is taken as objective function and Conditional Value-at-Risk is taken as a constraint. The model is solved by a particle...
This paper presents a scientific strategy for cycling induced by the functional electrical stimulation. In order to simulate the FES-cycling movement produced by human body, a neuro-musculo-skeletal model containing 16 segments and 186 muscles is developed, which can simulate human movements precisely. This model contains mathematical model of electrically stimulated skeletal muscles. Having known...
For the mesh warping and simulation automatically cease in multi-stage drawing numerical simulation of ultra-thin sheet, the reasons are analyzed and solutions are presented. Through pen shell multi-stage drawing it can be seen that adaptive meshing and correct control mass factor is the key to resolve the problems.
A public project evaluation approach from the perspectives of the stakeholders satisfaction and economic, social and environment impacts is proposed. The evaluation system of the stakeholders' satisfaction is comprised of the dimensions of stakeholders' information, expectation, actual perception, complaint and trust. The social, environmental and economic benefits and disbenefits of the project stakeholders...
