A framework for rapid local area modeling for construction automation

Rapid 3D positioning and modeling in construction can be used to more effectively plan, visualize, and communicate operations before execution. It can also help to optimize equipment operations, significantly improve safety, and enhance a remote operator's spatial perception of the workspace. A new framework for rapid local area sensing and 3D modeling for better planning and control of construction equipment operation is described and demonstrated. By combining human-assisted graphical workspace modeling with pre-stored Computer-Aided Design (CAD) models and simple sensors (such as single-axis laser rangefinders and remote video cameras), modeling time can be significantly reduced while potentially increasing modeling accuracy.

Review of methods to collect settled dust and isolate culturable microorganisms

Examination of settled dust is often included in investigations of indoor environments to identify the types and concentrations of particles to which building occupants may be exposed. Fungi and bacteria are among the many components in dust that have been studied. Isolation by culture is an established method that is used widely to quantify and identify microorganisms in environmental samples. However, no standard procedures for culturing fungi or bacteria from dust have been adopted widely to ensure the validity of comparing findings from different studies. This paper reviews methods various researchers have used to study surface particles and to isolate culturable microorganisms from dust. Factors that were found to differ included the method of sample collection, the ways dust was prepared for inoculation onto growth media, and the culture media chosen for specific categories of agents. The need for reference methods in environmental microbiology for use in the assessment of indoor environmental quality is discussed.

Non-linear analysis for the freezing–thawing situation of the rock surrounding the tunnel in cold regions under the conditions of different construction seasons, initial temperatures and insulations

In this paper, based on the governing differential equations of the problem of temperature field with phase change, the finite element formulae of this problem are obtained from Galerkin's method. An illustrative example of the temperature field in cold region tunnel under the conditions of the different construction seasons, different initial temperatures, different thicknesses and thermal conductivity of insulation material is provided. Then some significant results are presented, which can provide a reference for actual tunnel engineering designs in cold regions.     

乡村振兴语境下陇中地区生土建筑的保护与更新策略 ——以甘肃省定西市通渭县为例

近年来快速城镇化过程中，西北乡 村建设与地域文化发展出现了种种问题。 在乡村振兴战略的背景下，如何在复杂的城 乡系统中找到合适的切入点打通症结，解决 文化、空间、生态多系统的“乡村病”值得深 思。本文针对乡村发展的现实问题，以当地 普遍建设的生土建筑为切入点，以生态宜居 建设与地域文化传承为目标，提出一系列相 关保护与更新策略，并以定西市通渭县为例 探讨。策略包括在提炼当地传统民居生态特 性的基础上，以工程技术手段优化生土建筑 的材料性能与建筑结构，扩大生态与社会可 持续效益；凝练生土建筑文化特性为设计建 设基础，以技术研究、绿色教育与艺术活动 激活文化内生动力，并完善法规规范支持地 域文化传承。实现将生土建筑发展成果有策 略地整合，为西北乡村振兴实践提供参考。
