Based on Darcy flow production rate formula, functional relationship between relative permeability and water saturation as well as Archie's formulas, we have deduced the theoretical relationship of reservoir productivity with porosity, permeability and resistivity index. Moreover, we have made one reservoir productivity prediction model on the basis of conventional logging data using neural network...
This paper presents a new steady-state productivity equation for horizontal wells in gas reservoirs with upper and lower boundary enclosed. Firstly, the fundamental solution to the 3-D steady-state Laplace equation is derived with the philosophy of source and the Green function for a horizontal well located at the center of the laterally infinite gas reservoir, with considering the above boundaries...
Managed software development organizations are de facto closed loop systems, in which management actions influence future behavior based on observations of previous behavior thus forming a closed feedback loop. It is well known from control theory that a closed loop system might exhibit dynamics very different from the dynamics of its open loop components. Therefore, it is the goal of this work to...
This paper presents a new approach in cost estimation process that enhances a software cost estimation method called (Use Case Point method). Our promotion was a suggestion to use a set of sixteen factors which considered as the most influential factor in Jordan environment that are used to promote a COCOMO II model.
Mycophenolic acid (MPA) can be produced from Penicillium pinophilum by submerged fermentation. Here we reported the use of the Plackett-Burman design to screen the limiting components for MPA production and subsequent use the response surface methodology was employed to derive a statistical model for media optimization towards production of MPA. The results obtained of Plackett-Burman indicated limitations...
Enterprise Resource Planning (ERP) systems and firms performance aspects are currently experiencing an increasing interest from both the academic and business communities. Based on the resource-based view (RBV) theory this paper develops a research model to measure and examine determinants of ERP value in regards to the impact on small and medium enterprise (SME) performance. The model gathers industry...
Software effort estimation is one of the most important tasks in software engineering. Software developers conduct software estimation in the early stages of the software life cycle to derive the required cost and schedule for a project. In the requirements stage, where most software estimation is conducted, the available information is usually imprecise or incomplete. In this paper, a new regression...
Componentization is a Software Engineering (SE) strategy successfull in the development of new projects. Mainstream games use components that handle a set of functions elevant to a common aspect of a genre (e.g. real time strategy, first person shooter). However, Artificial Intelligence (AI) components, in spite of their great game play weight in current games, few has been researched and published...
Design of Experiments is a well-known method used to describe complicated processes in the way that we can recognize the dependencies between the input factors inside. Because of that we use this method in order to describe the personal performance process as a result from the individual employees' features. Adopting the FMEA over the different roles and responsibilities in the software process we...
A weir-type cascade solar still, integrated with latent heat thermal energy storage system, was designed with the view of enhancing productivity. Use of a heat storage system with 18kg mass (2cm thickness) of paraffin wax beneath the absorber plate keeps the operating temperature of the still high enough to produce distillated water during the lack of sunshine, particularly at night. Also, theoretical...
Foreign direct investment (FDI) inflow increases greatly since China's openness and whether FDI is conducive to promote China's technology advance via technology transfer still remains a controversial issue. The paper first uses a classical two-factor production function which divide the economy into domestic and foreign sector, then augments the model, taking into account the externalities by technology...
Whether monetary policy should directly respond to asset boom-bust cycles has been in debate for decades. This paper tries to answer the question from the collateral channel of assets on real economy. By adding a partially endogenous financial shock in a reduced-form New Keynesian model, we find optimal monetary policy exists in the trade-off between current economic growth and future financial instability...
R & D diffusion is the basis and prerequisite for the diffusion of technological innovation, especially the R & D diffusion effect of center city in science and technology plays an important role on the technological progress of surrounding region. This paper describes the systems theory of R & D diffusion and conducts both qualitative and quantitative analysis upon evaluation variables...
This paper presents the results of application of the parametrical regulation theory for economic growth of Kazakhstan national economy on the basis of the Lucas endogenous model with a personalized human capital. The parameters of the considered model are estimated using the statistical data of evolution of the Kazakhstan national economy. The parametric sensitivity of the model solution is surveyed...
As the new leading industry of China, the Internet of Things has drawn much more attention from academic domain. But the study of the industry is almost in qualitative analysis. This paper is going to use self- organization theory and methods, so as to reveal the evolutionary process of the Internet of Things. And put the Haken model into the use of the IOT companies which are on the security market,...
At present, the development of China's dairy industry is an important stage. On the one hand, foreign companies speed up the penetration of Chinese dairy industry; on the other hand, domestic dairy enterprises competed fiercely. It is necessary to objectively measure the contribution of various production factors and technical progress in dairy industry to development in order to achieve a better...
More and more Chinese contractors have joined in the global construction market in recent years. How to evaluate and upgrade self competitiveness is always an important issue for numerous Chinese international contractors. This paper proposes an AHP (Analytic Hierarchy Process) model to analyze essential competitiveness factors which based on experts' evaluation opinions from the international construction...
In view of the discontinuity of the data of service sectors due to the diameter change, firstly, the paper measures the total factor productivity growth of service sectors based on input-output tables. Then, using the panel data model, we test the relationship between offshore service outsourcing and the total factor productivity growth of services sectors. The result shows that, currently, offshore...
This article multi-reference frame(MRF) is used to simulate the impellers, and standard k − ε turbulent model and the resolve method of apart the velocity field from concentration field are used in the simulation, Through studying agitation effect including the flow field velocity distribution and the turbulent kinetic power diffusion situation in the double-decked oar trough's discovered in double-decked...
Population capacity is a strategic issues regarding ahieving urban sustainable development. Based on Grey System Theory and supply & demand balance model of work force, this paper put forward a calculated capacity of the economic population in each town of Dongguan from 2001 to 2007. An estimated capacity of future economic compacity of each town in Dongguan is also presented based on a compararison...
