The safety of post-earthquake structures is evaluated manually through inspecting the visible damage inflicted on structural elements. This process is time-consuming and costly. In order to automate this type of assessment, several crack detection methods have been created. However, they focus on locating crack points. The next step, retrieving useful properties (e.g. crack width, length, and orientation) from the crack points, has not yet been adequately investigated. This paper presents a novel method of retrieving crack properties. In the method, crack points are first located through state-of-the-art crack detection techniques. Then, the skeleton configurations of the points are identified using image thinning. The configurations are integrated into the distance field of crack points calculated through a distance transform. This way, crack width, length, and orientation can be automatically retrieved. The method was implemented using Microsoft Visual Studio and its effectiveness was tested on real crack images collected from Haiti.

Engineering changes (ECs) are raised throughout the lifecycle of engineering products. A single change to one component produces knock-on effects on others necessitating additional changes. This change propagation significantly affects the development time and cost and determines the product's success. Predicting and managing such ECs is, thus, essential to companies. Some prediction tools model change propagation by algorithms, whereof a subgroup is numerical. Current numerical change propagation algorithms either do not account for the exclusion of cyclic propagation paths or are based on exhaustive searching methods. This paper presents a new matrix-calculation-based algorithm which can be applied directly to a numerical product model to analyze change propagation and support change prediction. The algorithm applies matrix multiplications on mutations of a given design structure matrix accounting for the exclusion of self-dependences and cyclic propagation paths and delivers the same results as the exhaustive search-based Trail Counting algorithm. Despite its factorial time complexity, the algorithm proves advantageous because of its straightforward matrix-based calculations which avoid exhaustive searching. Thereby, the algorithm can be implemented in established numerical programs such as Microsoft Excel which promise a wider application of the tools within and across companies along with better familiarity, usability, practicality, security, and robustness. © 1988-2012 IEEE.

在传统的软件开发过程中,开发者更关注软件开发生命周期的管理,而对软 件开发后生命周期的管理并不热心。随着信息技术和互联网技术的快速发展,软 件产业发生了重大变革。新的软件运营模式要求对软件开发后生命周期管理提供 完善的支持。 本文首先回顾了传统的软件发布技术。PXE技术提供了网络远程引导功能, 该技术结合网络远程唤醒技术Wake-on-LAN使得通过网络远程控制客户机安装 操作系统成为可能。网络安装软件有基于网络克隆的Symantec Ghost和Windows Server 2003 RIS;有基于脚本的Kickstart;有基于镜像的SystemImager suite。在 开源系统中,APT是最为著名的包管理工具,它较为完善地解决了软件包之间的 依赖关系。网络更新技术则提供了更多的功能,目前的更新软件有:通用产品更 新器Install Shield, Power Update, Software Dock, Marimba等;以及供应商产品更 新器Microsoft Update, Windows Update, Microsoft SUS, Microsoft SMS, Norton AntiVirus LiveUpate等。 美国Colorado大学为软件开发后生命周期建立了一个体系结构Software Dock,并实现了一个粗略的原型系统。本研究侧重分析了应用软件的发布和恢 复机制,提出以用户的角度看待软件开发后生命周期管理的思想,建立了一个软 件发布机制体系结构,试图解决如下问题:系统重装后的运行态恢复,即系统崩 溃后如何快速而灵活地恢复到指定状态点并且重建该状态点的运行状态(即运行 态恢复);应用软件恢复透明化和即点即用。
