The development of modern services cannot do without the staffs in this field. As the global industry transfers from industrial economy to service economy, the labor demand for modern services keeps increasing. The research reviews labor demand theories and its various incidence impacts, and carries out forecast research and incidence research of the number of people engaged in services in the future...
Based on the development and utilization of the Tertiary groundwater in southern Xialiaohe aquifer, the development pattern of up Tertiary groundwater is established, the primary evaluating indicators include the extraction coefficient of groundwater, the over extraction coefficient of groundwater, the aquifer thickness, the chloride ion concentration, groundwater level, a new fuzzy identification...
This paper presents an extremum seeking control (ESC) scheme for energy efficient operation of chilled-water system, and Modelica based dynamic simulation models for demonstrating the effectiveness of the proposed control strategy. The simulated plant consists of a water-cooled screw chiller and a mechanical-draft counter-flow wet cooling tower. The ESC scheme takes the total power consumption of...
Because of its pursuit for a green GDP, low-carbon economy and a new energy solution to the energy crisis during the recent years, the Chinese government has been increasing support to the development of methane projects, resulting in rapid growth of the sector. However, the development of methane services has been lagging far behind, restricting the utilization of methane projects. This study provides...
Large numbers of studies have shown that: through the information sharing between enterprises upstream and downstream of supply chain, enterprises can improve their customer service quality, shorten payment cycles and reduce labor costs, so as to effectively alleviate the "bullwhip effect". However, the above studies of the supply chain were generally set up an absolute controlor, and used...
With the evolution of the concept of energy safety, international regional cooperation has become an important way to countries to solve energy issues. In the Northeast Asia the regional energy cooperation is an inevitable trend. However, due to the complexity of regional energy cooperation, the progress of the Northeast Asia regional energy cooperation is not smoothly. This paper by using the dynamic...
The issue of public service quality can be seen as an equilibrium process which includes the game between the supplier and the demander of the public service. The boundary rationality of the game participator in public service made the game process to be a process for the stable state. Based on the model of evolutionary game involving the supplier and demander of the public service, we find that the...
In wireless sensor network studies the main objective is minimizing the energy consumption so that the lifetime is maximized under the limited battery capacity constraints. In most event-driven surveillance applications, the end-to-end delay should also be minimized. In this paper we present a new EDO-MAC (energy and delay optimization Media Access Control) which reaches a good balance between energy...
Mitochondria are a vital organelle of eukaryotic cells. Many diseases are caused by the mitochondrial gene mutation , therefore, there is an urgent requirement to explore the proteins of mitochondrion. In this paper we have created a list of 1086 human mitochondrial genes by combining 13 datasets from publications or genomic experiments. Then we created a functional linkage network among mitochondrial...
This paper presents the growth effect of Chinese government non-tax revenue spending on its Gross Domestic Product (GDP) using the variance Decomposition Technique. The results show that Government Purchase (GP) expenditures have a significant explanatory power on the long-run economic growth. Whereas, Government Non-Tax Revenue Expenditure (GNR) and the Government Fundamental Investment (GFI) have...
Based on the System Dynamics theory and the causality of the factors influencing competency of mine special operators, this paper established a dynamic simulation model of Training function on the Influencing Factors of mine special operators' Competency. The studies showed, under the same training inputs, coping capacity, sense of security responsibility, and self-management skills have more visible...
Route plan decision making of road is of great important in the road design and later construction. For the traditional route selection methods can not meet the requirements of road construction, the paper aimed at the characteristics of route selection in the plain area to construct route selection decision making index system, which integrated qualitative and quantitative decision making indexes...
In the Korean Pine solid quantity's forecast technique, the characteristic of Korean Pine cone's shape is one of main parameters. This paper can provide the precise data for the Korean Pine solid quantity's forecast technique by segmenting the image of Korean Pine which is taken by the Filed Server. Considering of the complex background of Korean Pine image and the target of hollow contours, we proposed...
The present study on product service system (PSS) paid little attention to strategic lifecycle perspective, herein lost strategic sustainable for PSS, firms and service supply chains (SSC). To improve it, this paper critically reviewed the study on PSS, firm, and SSC etc. with strategic and tactical lifecycle perspective. Based on this review, it redefined PSS and put forward an evolution framework...
In this paper, the improved structural optimization algorithm of the flexible neural tree model is employed to select the parameters for the industrial production. With the highest accuracy and the shortest time to find the important parameters affecting the production so as to provide a theoretical support for the control of fluid industry production. In the period of learning of the flexible neural...
The introduction of Web 2.0 raises new problems of Internet content regulation. This paper sets up a three-person game model including government, Internet operators and prosumers and discusses the optimal regulation intensity of them both in non-cooperative and cooperative cases. The optimal regulation intensity in non-cooperative case is greater than that under the classical newsboy problem model...
An Enterprise is just like an organism whose survival depends on two aspects: health and energy sources. In Enterprises these two aspects refer to good management and continuous resource. So, the survival of Enterprises at least depends on two cycle systems: metabolism cycle system and resource balance cycle system. The unbalance between them can lead to Enterprisespsila failure. Metabolism cycle,...
DM ("device management") service is a new value- added service whose value chain has the typical characteristics of two-sided markets. Based on a review of the literature on two- sided market theory, the paper discusses pricing models for DM service with two agents on one side, which has not been addressed by previous research. The key to successful implementation of the DM service platform...
Energy consumption decomposition is a commonly used method when studying on influencing factors of energy consumption. The paper introduced a relatively reasonable decomposition method-logarithmic mean Divisia index decomposition (LMDI), and decomposed influencing factors of energy consumption into three parts: Scale effect affected by changes in gross production value, structural effect affected...
The simulated experiments are generally adopted to study the control performance of earth-pressure-balance system of shield machine economically and safely. But, the range and strength of simulated experiments are usually restricted by the physical conditions of simulated system. In this study, the simulation model of earth-pressure-balance simulated system of shield machine was established based...
