Design of Concrete Tunnel Linings for Fire Safety

An Image-Based System for Change Detection on Tunnel Linings

We present an automated system for detecting visual changes on tunnel linings. By registering new images to a three-dimensional tunnel surface model, recovered using Structure and Motion techniques, we are able to detect and localise changes accurately in order to assist visual inspection by a human expert. We formulate the problem of detecting changes probabilistically and exploit different fe...

Development of a Fire Safety Checklist for Dormitories

Background;Despite advances in technology, people are still exposed to fire hazard. Students can be one of the most important exposed groups. Therefore, fire safety inspection should be established in dormitories. The aim of this study was to develop a fire safety checklist for fire safety inspection in dormitories. Methods; This study was as a tool development followed by a cross-sectional st...

Road tunnel fire safety and risk: a review

A review concerning road tunnel fire safety and risk is presented. In particular different perspectives and methods on safety and risk are discussed. Road tunnel fire safety usually involves high uncertainty and high-stakes decisions. Thus, a wider group of stakeholders and different types of knowledge should be included in the fire safety analysis and evaluation, than what is required by techn...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
