ClimateAP: an application for dynamic local downscaling of historical and future climate data in Asia

Tongli WANG, Guangyu WANG, John L. INNES, Brad SEELY, Baozhang CHEN

摘要: While low-to-moderate resolution gridded climate data are suitable for climate-impact modeling at global and ecosystems levels, spatial analyses conducted at local scales require climate data with increased spatial accuracy. This is particularly true for research focused on the evaluation of adaptive forest management strategies. In this study, we developed an application, ClimateAP, to generate scale-free (i.e., specific to point locations) climate data for historical (1901–2015) and future (2011–2100) years and periods. ClimateAP uses the best available interpolated climate data for the reference period 1961–1990 as baseline data. It downscales the baseline data from a moderate spatial resolution to scale-free point data through dynamic local elevation adjustments. It also integrates and downscales the historical and future climate data using a delta approach. In the case of future climate data, two greenhouse gas representative concentration pathways (RCP 4.5 and 8.5) and 15 general circulation models are included to allow for the assessment of alternative climate scenarios. In addition, ClimateAP generates a large number of biologically relevant climate variables derived from primary monthly variables. The effectiveness of the local downscaling was determined based on the strength of the local linear regression for the estimate of lapse rate. The accuracy of the ClimateAP output was evaluated through comparisons of ClimateAP output against observations from 1805 weather stations in the Asia Pacific region. The local linear regression explained 70%–80% and 0%–50% of the total variation in monthly temperatures and precipitation, respectively, in most cases. ClimateAP reduced prediction error by up to 27% and 60% for monthly temperature and precipitation, respectively, relative to the original baselines data. The improvements for baseline portions of historical and future were more substantial. Applications and limitations of the software are discussed.

摘要: The effects of biologically active carbon (BAC) filtration on haloacetic acid (HAA) levels in plant effluents and distribution systems were investigated using the United States Environmental Protection Agency’s Information Collection Rule (ICR) database. The results showed that average HAA5 concentrations in all locations were 20.4 μg·L and 29.6 μg·L in ICR plants with granular activated carbon (GAC) and ICR plants without GAC process, respectively. For plants without GAC, the highest HAA levels were observed in the quarters of April to June and July to September. However, for plants with GAC, the highest HAA levels were observed in the quarters of April to June and January to March. This HAA level profile inversely correlated well with water temperature, or biologic activity. For GAC plants, simulated distribution samples matched well with distribution system equivalent samples for Cl AA and THMs. For plants with and without GAC, simulated distribution samples overestimated readily biodegradable HAAs in distribution systems. The study indicated that through HAA biodegradation, GAC process plays an important role in lowering HAA levels in finished drinking water.

摘要:

Productivity has often been cited as a key factor in a flexible manufacturing system (FMS) performance, and actions to increase it are said to improve profitability and the wage earning capacity of employees. Improving productivity is seen as a key issue for survival and success in the long term of a manufacturing system. The purpose of this paper is to make a model and analysis of the productivity variables of FMS. This study was performed by different approaches viz. interpretive structural modelling (ISM), structural equation modelling (SEM), graph theory and matrix approach (GTMA) and a cross-sectional survey within manufacturing firms in India. ISM has been used to develop a model of productivity variables, and then it has been analyzed. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are powerful statistical techniques. CFA is carried by SEM. EFA is applied to extract the factors in FMS by the statistical package for social sciences (SPSS 20) software and confirming these factors by CFA through analysis of moment structures (AMOS 20) software. The twenty productivity variables are identified through literature and four factors extracted, which involves the productivity of FMS. The four factors are people, quality, machine and flexibility. SEM using AMOS 20 was used to perform the first order four-factor structures. GTMA is a multiple attribute decision making (MADM) methodology used to find intensity/quantification of productivity variables in an organization. The FMS productivity index has purposed to intensify the factors which affect FMS.

摘要: Chronic non-communicable diseases have become a major threat to humanity. International studies have shown that of 57 million deaths worldwide in 2008, 36 million (63%) were caused by chronic non-communicable diseases; of these, 29 million (80%) occurred in low and middle income countries. The WHO predicts that if the current trend continues, the annual number of deaths due to chronic non-communicable diseases will increase to 55 million by 2030. Due to acceleration of industrialization and urbanization, along with population aging and rapid changes of people’s lifestyle, the morbidity and mortality from chronic diseases are rapidly increasing in China. Therefore, dealing with the prevalence of chronic non-communicable diseases has become one of the current major health issues for China to address. On the basis of summarizing the status of major chronic diseases in China, analyzing the key issues and key factors in chronic disease prevention and control, and reviewing and summarizing the experience from the previous projects, this paper proposes the following recommendations as strategies for chronic disease prevention and control and development of relevant system, which China should adopt. All relevant government departments should formulate corresponding policies; establish a coordinated and efficient work system with rational structure and clear division of tasks and responsibilities within the system. Implementation and development of “integrated medicine” in system is necessary. Work norms and requirements will then improve the performance and efficiency in chronic disease prevention and control in China.

摘要:

信息通信技术(ICT)和网络物理系统(CPS)的快速发展,为智能产品的日益普及铺平了道路。情境感知是衡量产品智能的一个重要角度。与人工制品不同,各种生物系统具有非凡的情境感知能力。生物启发式设计(BID)是最常用的设计策略之一。然而,迄今为止,很少有研究检查过情境感知智能产品的生物启发式设计。本文提出了一个结构化设计框架,用以支持情境感知智能产品的生物启发式设计。本文从产品设计的角度定义了情境感知的概念。该框架以功能-行为-结构理论(the situated function-behavior-structure ontology)为基础开发而成。本文规定了结构化设计过程,借助各种生物启发,支持不同的概念设计活动,如问题形成、结构重构、行为重构和功能重构。一些现有的设计方法和新兴的设计工具被纳入框架。本文提出了一个案例研究,展示了如何利用该框架重新设计机器人吸尘器,使其更具有情境感知能力。

High-order moment methods for LRFD including random variables with unknown probability distributions

Zhao-Hui LU, Yan-Gang ZHAO, Zhi-Wu YU

《结构与土木工程前沿(英文)》 2013年 第7卷 第3期   页码 288-295 doi: 10.1007/s11709-013-0210-1

摘要: The reliability-based load and resistance factors design (LRFD) has been widely used in the structural design codes. In almost all of the current reliability methods for the determination of the load and resistance factors, the basic random variables are assumed to have known probability distributions. However, in reality, the probability distributions of some of the basic random variables are often unknown due to the lack of statistical data. In this paper, the high-order moment methods for LRFD including random variables with unknown probability distributions are proposed. From the investigation of the present paper, it can be concluded that: 1) The load and resistance factors can be determined even when the probability distributions of the basic random variables are unknown; 2) The present method is convenient and more effective in estimating the load and resistance factors in practical engineering since it needs neither the iterative computation of derivatives nor any design points; 3) In the applicable range of the high-order moment method, although the load and resistance factors obtained by the proposed method may be different from those obtained by first order reliability method (FORM), the target mean resistances obtained by both methods are essentially the same.
