The Vallejo Sanitation and Flood Control District is performing CCTV inspections on pipes that do not have a record of such inspections. This effort was triggered by a settlement with Baykeeper, who alleged that broken pipe or pipe about to collapse would remain undetected and lead to sanitary sewer overflows. The actual result of the CCTV inspection turned out to be quite different. Instead of...

Using a dataset of over 1.6 million inspections by the Occupational Safety and Health Agency (OSHA) from 1990 through 2010, we explore the determinants of inspection and enforcement outcomes. OSHA is an institutionally split agency, with the federal agency conducting inspections in 25 states and state agencies conducting inspections in the remaining 25. The geographic variety and range over 21 ...

BACKGROUND Unintentional, non-fire-related carbon monoxide (CO) poisoning is a leading cause of poisoning death and injury in the USA. Residential poisonings caused by faulty furnaces are the most common type of CO exposure. However, these poisonings are largely preventable with annual furnace inspections and CO alarm installation. OBJECTIVE This study aimed to identify the knowledge, attitud...

We analysed two consecutive inspection reports for each of 136 British zoos made by government-appointed inspectors between 2005 and 2011 to assess how well British zoos were complying with minimum animal welfare standards; median interval between inspections was 1,107 days. There was no conclusive evidence for overall improvements in the levels of compliance by British zoos. Having the same zo...

Ultrasonic phased arrays are a new technology that offers considerable potential for inspecting construction welds. Using electronic control of the beam, phased arrays can scan, sweep, steer and focus the ultrasound. Since welds typically produce defects of known character and orientation, phased arrays can be programmed to optimize weld inspections. These inspections include standard ASME-type...

Forestry management requires careful and intensive planning efforts to ensure optimal yield, ecological stability, and regulatory compliance. In this paper, we describe a method of identifying wetlands and producing maps of their extent from commonly available, remotely-sensed imagery. This method provides a large labor savings over both field inspections and manual photo inspections. The enhan...

The goal of software inspections and tests is to reduce the expected cost of software failure over the life of a product. This paper extends the use of defect triggers, the events which cause defects to be discovered, to help evaluate the e ectiveness of inspection and test activities. In the case of inspections, the defect trigger is de ned as a set of values which associate the skills of the ...
