Parallelization of MRCI based on hole-particle symmetry

The parallel implementation of multireference configuration interaction program based on the hole-particle symmetry is described. The platform to implement the parallelization is an Intel-Architectural cluster consisting of 12 nodes, each of which is equipped with two 2.4-G XEON processors, 3-GB memory, and 36-GB disk, and are connected by a Gigabit Ethernet Switch. The dependence of speedup on molecular symmetries and task granularities is discussed. Test calculations show that the scaling with the number of nodes is about 1.9 (for C1 and Cs), 1.65 (for C2v), and 1.55 (for D2h) when the number of nodes is doubled. The largest calculation performed on this cluster involves 5.6 x 10(8) CSFs.

Use of military training doctrine to predict patterns of maneuver disturbance on the landscape. I. Theory and methodology

Modern-day military maneuvers, involving tactical formations of wheeled and tracked vehicles, can have significant physical and environmental impacts on the landscape. Numerous scientific studies of these impacts have been conducted, most notably the post-impact assessments of General Patton’s tank maneuvers of the early 1940s in the Mojave Desert of California and Arizona. On a smaller scale, numerous studies of military vehicle impacts have been conducted on military training lands throughout the United States, Canada and Europe. These studies have used a variety of measurement techniques, to include ground level photography and in situ measurements, aerial photography, satellite imagery and vehicle-mounted global positioning systems (GPS) data to define the footprint, patterns and magnitude of disturbances on the landscape. These disturbances are highly variable and can occur over tens of thousands of acres. Because scientists and land managers are generally not familiar with military decision-making, tactical doctrine, and vehicle–weapons systems capabilities, it is difficult for them to predict patterns of disturbance a priori. Even during post-event impact analysis, a full understanding of why and how maneuver disturbance patterns occur may not be readily apparent to them. This limitation can preclude knowledgeable planning, design and repair of damaged lands. In this case study, military tacticians and physical scientists developed an integrated methodology to predict these disturbance patterns more explicitly. The goal of the study was to provide land managers with a tool for understanding how these patterns evolve, and in turn, allow them to better plan and design mitigation efforts to sustain the landscape. The methodology combines a military terrain analysis technique, the modified combined obstacle overlay (MCOO), with an applied military tactics filter to predict where vehicle impacts would be most likely. A terrain and tactical analysis of the landscape at the Combat Maneuver Training Center-Live Fire (CMTC-LF) Area at the US Army Grafenwöhr Training Area, Germany, was conducted using maps, digital ortho-photography, spatial data and on-site reconnaissance to determine the tactical footprint and potential disturbance patterns caused by a new training mission. Part I of this study describes the background, theory and approach used to develop the methodology. Part II describes the field-based validation of the methodology, using post-maneuver ground observations and sampling to test the methodology’s predictions.     

景观设计要素的分析

户外居住环境设计研究

中国的城市正在以前所未有的速度发生着翻天覆地的变化,昨日辉煌迷人的旧住区今天却成为了时代的落伍者,整片整片的新居住区拔地而起。在不同的时代,人类有不同的生活理想和生活方式,经过一代代的历史沉淀,形成不同的居住文化。时至今日,传统难以为继,在居住环境方面我们的做法往往是先排房子,后作环境,这就带来了一系列问题：户外环境千篇一律、人文特色与户外环境活力丧失、缺少了地域特色等等。因此需要我们认真去研究,寻找一条出路。     

当代旧居住建筑的改造设计策略

旧居住建筑沿街空间环境是指以旧居住建筑为界面形成的街道空间环境,涉及的问题包括街道空间的比例形式,以及街道的环境质量。旧居住建筑沿街空间作为与居民最为贴近的城市公共空间,在居民的日常生活中扮演着重要的角色。希望通过这一研究对现阶段城市旧居住建筑的沿街空间环境提供一些有益的借鉴,并且能通过对某些街道空间环境元素的调整来改善己有的不良街道空间,来全方位地、真正地提升我们的城市形象和生活品质。
