浅谈传统雨水井缺点的改造

市政整体排水系统程序如下:路面雨水→雨水井→沉泥井→过街排水管→排水检查井→地下排水主干线。其中雨水井,沉泥井,过街排水管部分多数由道路主体施工单位完成。雨水井也叫收水口,市政道路上的雨水井平蓖是其中的一部分,雨水井常见的有两种:一种是八六式雨水井,上下两件套。一种是带沉泥井的双蓖式雨水井,八件套。本文将就这两种雨水井的相关缺点改造进行讨论。

Cost data quality considerations for eco-efficiency measures

Cost data are a central aspect of eco-efficiency measures, either as means to assess value of production, or, more directly, as one dimension of the efficiency ratio. Several aspects may affect the quality of cost data, among them definitions, time and space, and confidentiality issues. Somewhat surprisingly, cost data quality has received little attention in the field of sustainability and eco-efficiency so far. Even worse, perhaps, is the lack of tools suitable for a cost data quality assessment and management.This paper discusses parameters that affect cost data quality, and will then propose a pedigree matrix as a tool designed for managing cost data quality issues. The application of the matrix is described, also in combination with a previously proposed, and broadly used, pedigree matrix for environmental data quality management.

Thailand's Policy Challenges

Thailand's real gross domestic product growth has fallen to a permanently lower trend, making it the worst performer in the Southeastern Asian region. The export sector, the country's long‐standing growth engine, has sputtered due to the declining competitiveness of the manufacturing sector. Chronic political instability during the last two decades has resulted in the adoption of short‐sighted policies, in particular, populist policies designed specifically to garner votes rather than improve the long‐term productivity of the business sector. The military coup was expected to restore political stability and end costly populist policies introduced by elected civil governments. Unfortunately, as the military government develops its long‐term political aspirations, it, too, seeks the assistance of populist policies to ensure its political success. Thailand has promulgated laws and regulations to ensure fiscal discipline, but it has yet to be seen whether the letter of the law can help prevent such populist policies in practice.     

地下综合管廊基坑支护方案经济评价及优化探讨

目前城市地下综合管廊通常采用明挖基坑进行施工。城市地下综合管廊由于结构体量大,整体埋深较深,因此基坑支护费用较高,有的地下综合管廊基坑支护费用甚至超过管廊主体结构费用。在综合管廊主体结构规模确定的情况下,管廊基坑支护方案的选择往往决定了综合管廊整体工程造价的高低,因此控制综合管廊基坑支护的造价是控制综合管廊整体造价的重要内容。文章在对地下综合管廊常用基坑支护方案的适用条件、造价指标、优缺点进行经济评价的基础上,提出了综合管廊施工图设计和施工方案设计时基坑支护方案的选择原则,探讨了基坑支护方案的优化方向,并以某综合管廊项目基坑支护为例,详细介绍了具体的优化内容,以供大家参考。

Bayesian Model Averaging: A Systematic Review and Conceptual Classification

Bayesian model averaging (BMA) provides a coherent and systematic mechanism for accounting for model uncertainty. It can be regarded as an direct application of Bayesian inference to the problem of model selection, combined estimation and prediction. BMA produces a straightforward model choice criterion and less risky predictions. However, the application of BMA is not always straightforward, leading to diverse assumptions and situational choices on its different aspects. Despite the widespread application of BMA in the literature, there were not many accounts of these differences and trends besides a few landmark revisions in the late 1990s and early 2000s, therefore not accounting for advancements made in the last decades. In this work, we present an account of these developments through a careful content analysis of 820 articles in BMA published between 1996 and 2016. We also develop a conceptual classification scheme to better describe this vast literature, understand its trends and future directions and provide guidance for the researcher interested in both the application and development of the methodology. The results of the classification scheme and content review are then used to discuss the present and future of the BMA literature.     

A map traceability management scheme for security control

ABSTRACT

A map traceability management scheme for security control is proposed utilising visual cryptography and Quick Response Code. The map information is classified into two categories: the public information MPI and the traceable map information MTI, and they are both converted into QR codes. Map shares MS and control shares CS are generated according to extended multiple visual cryptographic scheme. MPI can be obtained by scanning the MS, while MTI can be got by overlaying the MS on CS which is only accessible to management units, so it can identify every map and provide the basis for the traceability management.
