This study provides an economic evaluation for a Land Ferry, which is a rail system capable of carrying trucks and all other types of vehicles, passengers, and cargo. The Land Ferry system involves a sliding loading system to roll heavy loads onto a flatbed; as a result, loading and unloading of all vehicles and cargo could be accomplished simultaneously. The evaluation for this system included...

We study the concept of Ferry based Wireless Local Area Network (FWLAN), in which a number of isolated nodes are scattered over some area and where communication between a node and the outer world, or communication between the nodes, are made possible via a message ferry. The Ferry has a predetermined cyclic path which collects packets from a node and delivers packets to it when it is in the vi...

In some particular environments such as battlefield, disaster recovery and wide area surveillance, most existing routing algorithms will fail to deliver messages to their destinations. Thus, it is an important research issue of how to deliver data in disconnected wireless sensor networks. This paper presents two efficient message ferry routing algorithms, denoted as MFRA1 and MFRA2, for data co...

the new field of research into the ethical, legal and social aspects of scientific and technological developments (ElSa) is rapidly becoming a professional field with grants, research programmes and university departments devoted to it. at first glance, ElSa seems to be a new development intended to address questions and challenges that arise from advances in the natural sciences. the professio...

Workstation processing power and the number of available workstation application tools have increased dramatically in the last five years. Sophisticated users now find that "real work" can be accomplished on CAD/CAE workstations. In "Conversion of an IC Design Capability from a Mainframe to a Workstation Environment," Dave Palmer and John Wisniewski from Sandia National Laboratories recount the...

Ferries and other passenger vessels provide a crucial mode of transportation for many in the developing world, especially in archipelagic nations like Indonesia and in river delta nations like Bangladesh. However, this dependence on passenger vessels coincides with a high rate of accidents and fatalities in many countries, linked to purchase of old, substandard, and/or inappropriate vessels in ...

Ferry-based networks provide a means of bringing extremely low-cost Internet access to remote rural areas, where conventional access technologies, e.g., dial-up, DSL and CDMA, are currently economically infeasible. We present an architecture for ferry-based networks and identify downlink scheduling as a difficult open problem. We argue that opportunistic scheduling policies that take ferry sche...

Recent studies in the assessment of risk in maritime transportation systems have used simulation-based probabilistic techniques. Amongst them are the San Francisco Bay (SFB) Ferry exposure assessment in 2002, the Washington State Ferry (WFS) Risk Assessment in 1998 and the Prince William Sound (PWS) Risk Assessment in 1996. Representing uncertainty in such simulation models is fundamental to qu...

Ferry accidents often occur the result of ship handling difficulty which interfacing human, machine and environment. Therefore, a decision tool model as a comprehensive information system, based on the ship handling difficulty, needs to be developed through the combination of Analytic Hierarchy Process (AHP) and Fuzzy Logic System. The Fuzzy Logic System part consists of ship condition, ship ha...
