Modern road transport systems rely on information from sensors to operate safely and efficiently. The sensors are typically used to provide vehicle counting, occupancy, speed measurement...

Experiments with Formal Specifications on MAGGALY
Until lately, safety functions for automatic train driving systems have mostly been implemented with classical techniques such as relays, way circuitry and, more recently, electronic devices....

Safety Microprocessors in Guided Ground Transport
The use of microprocessors performing safety tasks such as Automatic Train Protection systems made more difficult their safety-worthiness assesment. In this paper we will first examine...

The U.K. Marina Industry?An Overview
This paper is written from the point of view of an established marina developer and operator and, as the title suggests, it purports to be nothing more than an overview of a number of...

Load Sharing Benefits of Composite Pile Systems
The paper develops design techniques which will allow piled systems to be extended into more onerous operating conditions. In storm events marinas always develop failure mechanisms at...

Performance Specifications for Floating Docks
The paper reflects the lessons learned by the writer thru involvement with the floating dock industry since the middle 1960's as both a manufacturer and a consultant. Sections...

Ice Engineering Design for Marinas
Northern marinas must be designed for the effects of ice and winter conditions. Marina sites, although themselves specific, experience forces and actions that can be predicted and generalized...
