Reservoir parameter inversion based on weighted statistics

Variation of reservoir physical properties can cause changes in its elastic parameters. However, this is not a simple linear relation. Furthermore, the lack of observations, data overlap, noise interference, and idealized models increases the uncertainties of the inversion result. Thus, we propose an inversion method that is different from traditional statistical rock physics modeling. First, we use deterministic and stochastic rock physics models considering the uncertainties of elastic parameters obtained by prestack seismic inversion and introduce weighting coefficients to establish a weighted statistical relation between reservoir and elastic parameters. Second, based on the weighted statistical relation, we use Markov chain Monte Carlo simulations to generate the random joint distribution space of reservoir and elastic parameters that serves as a sample solution space of an objective function. Finally, we propose a fast solution criterion to maximize the posterior probability density and obtain reservoir parameters. The method has high efficiency and application potential.

用于FSVM抑噪的统计型模糊权重函数

提出了用于设计模糊支持向量机(FSVM)的统计型模糊权重函数,该函数基于模式分类思想为每个训练数据建立一个分类面,数据的模糊权重根据分类面对2类数据的识别率来计算.靠近分类间隔的疑似噪声/离群点将获得相对较小的模糊权值,其作用受到抑制;而远离间隔区域的数据不容易受到盲目抑制.该方法能够有效识别噪声/离群点,降低它们对分类器的影响.实验验证了所提方法的合理性和有效性.统计型模糊权重函数对于含噪情况未知的训练数据尤其显得重要,因为数据含噪情况可以籍由函数分类功能得到恰当的估计.

Multi-objective integrated optimization based on evolutionary strategy with a dynamic weighting schedule

The evolutionary strategy with a dynamic weighting schedule is proposed to find all the compromised solutions of the multi-objective integrated structure and control optimization problem, where the optimal system performance and control cost are defined by H2 or H∞ norms. During this optimization process, the weights are varying with the increasing generation instead of fixed values. The proposed strategy together with the linear matrix inequality （LMI） or the Riccati controller design method can find a series of uniformly distributed nondominated solutions in a single run. Therefore, this method can greatly reduce the computation intensity of the integrated optimization problem compared with the weight-based single objective genetic algorithm. Active automotive suspension is adopted as an example to illustrate the effectiveness of the proposed method.

模糊数学方法与统计赋权

构建统计指标体系进行社会现象的综合评价,其中一个关键性技术难题是指标值的归并和指标权数的确定。由于一个指标系统中包含多个指标,有主有次、有轻有重,为了保证量化分析和评价测定的精度,有必要在对指标值汇总时给不同的指标赋以不同的权数。 实践中,一般的统计赋权是采用专家调查法,该法是将指标系统以调查问卷的形式送达给有关专家,由被邀请的专家给系统中的各指标赋以不同的权值。

Recalculating Sino-US Trade Balance Using the Ownership-Based Statistical Method

Using the trade statistical method based on asset ownership,this paper recalculated Sino-US bilateral trade volume and the result indicates that against traditional trade statistics,Chinese exports to the US reduced by an average of 51%while Chinese imports from the US increased by an average of 41%between 2004 and 2010.Balance of trade is in the range between US$2,189 billion of deficit and US$12.77 billion of surplus on the part of China,which are far smaller than the balance of Sino-US trade calculated by traditional statistical method.In order to reflect the real scale of China's foreign trade and effectively respond to Sino-US trade frictions,it is necessary for China to establish its trade statistics system based on asset ownership.

The Impact of Rural Women＇s Land Rights on Food Production in the Brong-Ahafo Region of Ghana

The poor performance of the agricultural sector as reflected in high prices of food stuffs as well as huge importation of food has been a major concern to many governments in Africa. Agriculture remains the backbone of Ghana＇s economy and women who constitute about 70% to 80% of farm labour face discrimination in terms of means of production such as land. The purpose of this study is to assess the impact of women＇s land rights on food production in the Brong-Ahafo region which is Ghana＇s food basket. Several land reforms have been instituted to ensure equitable access to land in order to enhance food production, yet the study reveals that many women have limited or no access to land and experience insecurity of tenure, which affects their farming methods, choice of crops grown, and production levels, consequently, resulting in low incomes and poverty. Relevant Primary Rate Access （RPRA） tools were used to gather data. The data were analyzed through descriptive statistics using Statistic Package for Social Science （SPSS） and Microsoft soRwares and presented into percentages, tabulation, and graphics. The research also revealed that the lack of awareness and education on land reforms and policies coupled with escalating land prices and complicated land transaction method are the major challenges to women＇s access and security over land. The study recommends the decentralization of the land title registration process, gender mainstreaming in the land title registration process, and intensification of advocacy on land rights, among others as crucial to improve women＇s access, control, and security over land for agricultural purposes

China-US Trade Balance under the Ownership-based Statistical System

In the context of economic globalization,territory-based bilateral trade statistics are no longer compatible with the reality of cross-border flow of capital factor and rapid emergence of multinational firms.On the basis of survey of literature studies,this paper has created a three-country model of bilateral trade based on ownership principle and demonstrated that ownership-based statistical system under this model can reflect bilateral trade volume and balance more objectively,truthfully and comprehensively.In addition to theoretical demonstration,this paper has revaluated China-US trade balance using ownership-based statistical methodology and the result indicates that the existing statistical system of trade severely overestimates the real level of China-US trade balance and FDI in China is a major reason behind increasing China-US trade surplus.

Application of whole body diffusion weighted imaging in bone metastasis

Objective： We evaluated （Whole-Body Diffusion Weighted Imaging, WB-DWl） application in bone metastasis. Methods： WB-DWI with GE 1.5T MR/I was performed on 10 healthy volunteers and 35 patients. WB-DWl and ECT was performed in all 35 patients. Using WB-DWl for detecting bone metastasis and compared them with that of ECT. Results： Background was suppressed in WB-DWl, fat, muscle, vessels and liver appeared same as background. Skeleton showed medium or slightly lower signal. Lymph nodes, some glandular organs, kidneys displayed medium signal. Spleen, testicle, brain tissue were low signal. Bladder, gallbladder were depicted as low signal because of ＂T2 through＂. Bone metastasis were multitude and inequality of size, punctiform, nodosity, column low intensity. Concordance between WB-DWI and ECT was seen in 4 cases. WB-DWl displayed 1 bone metastasis on skull, 46 on rib and sternum, 3 on scapula, 4 on extremities, 83 on vertebral, 36 on pelvic bone. ECT showed 2 bone metastasis on skull, 62 on rib and sternum, 7 on scapula, 9 on extremities, 64 on vertebral, 19 on pelvic bone. WB-DWl was 74% for bone metastasis on rib and sternum, ECT was 77%, 53% for vertebral and pelvic bone. All of the focus were statistics analyses, P 〈 0.05. Total probability distribution inequality if metastasis on different positions. Conclusion： WB-DWI was an effective imaging technology for screening bone metastasis.

Environmental Impact Optimization of Reinforced Concrete Slab Frame Bridges

The main objective of this research is to integrate environmental impact optimization in the structural design of reinforced concrete slab frame bridges in order to determine the most environment-friendly design. The case study bridge used in this work was also investigated in a previous paper focusing on the optimization of the investment cost, while the present study focuses on environmental impact optimization and comparing the results of both these studies. Optimization technique based on the pattern search method was implemented. Moreover, a comprehensive LCA （life cycle assessment） methodology of ReCiPe and two monetary weighting systems were used to convert environmental impacts into monetary costs. The analysis showed that both monetary weighting systems led to the same results. Furthermore, optimization based on environmental impact generated models with thinner construction elements yet of a higher concrete class, while cost optimization by considering extra constructability factors provided thicker sections and easier to construct. This dissimilarity in the results highlights the importance of combining environmental impact （and its associated environmental cost） and investment cost to find more material-efficient, economical, sustainable and time-effective bridge solutions.

Adaptive Noise Detection and Removal Algorithm Using Local Statistics for Salt-and-Pepper Noise

In this paper, an adaptive noise detection and removal algorithm using local statistics for salt-and-pepper noise are proposed. In order to determine constraints for noise detection, the local mean, varianoe, and maximum value are used. In addition, a weighted median filter is employed to remove the detected noise. The simulation results show the capability of the proposed algorithm removes the noise effectively.

Value Creation of Business Process Management （BPM） and Managerial Accounting System （MAS）： A Case Study

This paper explores the value creation of business process management （BPM） and managerial accounting system （MAS） using a case study. The findings show that BPM shortens the management chain and increases the connections among functions in the organization by right reassignment. Accounting indicators in MAS provide necessary information about business processes, which assists performance evaluation in BPM, and meanwhile, incentive schemes give enough motives, which guide employees to take actions in accordance with the organizational strategies and processes＇ goals. The information effect and motive effect of MAS increase employees＇ work satisfaction and their cooperation with each other. In the end, the integration of BPM and MAS improves the organizational economic performance, thus creating value for the organization. The results explain the reason why so much BPM fails in practice, because right assignment, performance evaluation system, and incentive schemes constitute organizational architecture, which is critical to organizational value. Additionally, the value creation of BPM and MAS depends on their coordination with the external environment, the internal situation, and the organizational strategy. From the view of managerial accounting perspective, MAS not only changes with the organization development but also facilitates the organization development.

Car Ownership and the Impact of Built Environment, Demographics and Transport Systems

Auto ownership is one of the most important linkages between travel demand and land use. Residents in denser, urban or more transit accessible neighborhoods tend to own fewer cars. Car ownership influences almost all aspects of travel behavior, including travel frequency, travel distances, mode choice and time-of-day choice. At the same time, car ownership affects residential location choices, as households owning cars are less likely to choose urban neighborhoods than households without cars. This paper describes a new microscopic auto-ownership model that has been estimated with survey data. The model is fully integrated with a land use and a transportation model to capture： （1） how owning a car affects travel behavior and location choice; and （2） how the built environment and the transportation needs affect auto-ownership decisions. The model has been validated against census data and is fully operational.

QUANTUM THEORY FOR THE BINOMIAL MODEL IN FINANCE THEORY

In this paper, a quantum model for the binomial market in finance is proposed. We show that its risk-neutral world exhibits an intriguing structure as a disk in the unit ball of R^3, whose radius is a function of the risk-free interest rate with two thresholds which prevent arbitrage opportunities from this quantum market. Furthermore, from the quantum mechanical point of view we re-deduce the Cox-Ross-Rubinstein binomial option pricing formula by considering Maxwell-Boltzmann statistics of the system of N distinguishable particles.
