The approach and landing is a complex phase of flight, in which flight crews need to conduct a series of procedures in a condensed time frame to make the approach stable. Unstable approaches can lead to events with reduced safety margins and additional operating cost. To ensure flights have stable approaches, airlines have established stabilized approach criteria to make sure the landing flight...

We present our solution to the crew-scheduling problem for North American railroads. (Crew scheduling in North America is very different from scheduling in Europe, where it has been well studied.) The crew-scheduling problem is to assign operators to scheduled trains over a time horizon at minimal cost while honoring operational and contractual requirements. Currently, decisions related to crew...

This paper reports some results of a long-term work in application of AI techniques whose ultimate goal is the development of tools for resource scheduling. Most of the efforts so far have been devoted to crew scheduling in railways and the resulting tool is called CREWS. CREWS contains the basic knowledge for crew scheduling, remains constant across companies, and only needs to be extended wit...

INTRODUCTION This study focus on the incidence of asbestos-related cancers among 28,300 officers and enlisted servicemen in the Royal Norwegian Navy. Until 1987, asbestos aboard the vessels potentially caused exposure to 11,500 crew members. METHODS Standardized incidence ratios (SIR) were calculated for malignant mesothelioma, lung cancer, and laryngeal, pharyngeal, stomach, and colorectal c...

Use cases have become an important tool in software engineering. There has been much focus on the diagram notation but relatively little on use-case descriptions. As part of a welcome and important research project into the use of scenarios in requirements engineering, the CREWS team has proposed a set of guidelines for writing use-case descriptions. This paper describes the replication of a CR...

BACKGROUND There is an increasing global burden of disease from injuries. Models of trauma care initially developed in high-income countries are also being adopted in low and middle-income countries (LMIC). Amongst these ambulance crews with Advanced Life Support (ALS) training are being promoted in LMIC as a strategy for improving outcomes for victims of trauma. However there is controversy as...

Chinese express highway has following characteristics: incomplete control of access, divided directions, multiple lanes, heavy volume of traffic, high speed, severe lateral disturbance, etc. These lead to the highest traffic accident rate and death rate, which makes these express highways become the most unsafe highways in China. This study focuses on express highway to analysis its representat...
