A family of LAN (Local Area Network) protocols is presented. The LAN consists of a pair of unidirectional fiber optic buses to which stations are connected via passive taps. The protocols provide round-robin bounded delay access to all stations. Contrary to most roundrobin access schemes, the protocols do not require transmission of special packets (tokens); rather, they simply rely on the dete...

A new media access protocol is presented for time and wavelength division multiplexed optical passive star networks. The protocol is based on a new \Bus-Mesh" virtual topology. The network provides minimum latency and high throughput while requiring only a single xed wavelength transmitter and receiver at each station. The use of non-agile, xed wavelength devices, readily available with current...

This research employs dielectrophoresis (DEP) force to separate and manipulate bio-particles. Exchanging electro-field attempts to separate different kinds of bio-particles (yeast, cells, micropolystyrene beads, or virus), and to manipulate particles to move simultaneously. The purpose of manipulation is moving bio-particles to next station on an integrated chip. In order to simplify experiment...

To fix ideas, we can think of the graph as a public transportation network, where each edge represents a bus route connecting two stations. The n players can be thought of as employees that want to commute from their home stations si to a company located at station t. Assume that the operation of each route requires a fixed amount of money, say one unit of cost, which people using that route ca...

The distributed queue dual bus (DQDB) protocol, the media access protocol of the IEEE 802.6 standard for metropolitan area networks, does not fully take advantage of the capabilities of a dual bus architecture. Although a fair bandwidth distribution among the stations is guaranteed when using the socalled bandwidth balancing mechanism, the protocol requires a considerable amount of time to adju...

The Americans with Disabilities Act (ADA) specifies guidelines covering the securement system and environment for wheeled mobility device (WhMD) passengers on the public bus system in the United States, referred to as the wheelchair tiedown and occupant restraint system (WTORS). The misuse or disuse of the WTORS system can be a source of injury for WhMD passengers riding the buses. The purpose ...

With the advances in industry and commerce, passengers have become more accepting of environmental sustainability issues; thus, more people now choose to travel by bus. Government administration constitutes an important part of bus transportation services as the government gives the right-of-way to transportation companies allowing them to provide services. When these services are of poor quali...

We discuss the concept of ultrasound imaging at a distance by presenting the evaluation of a customized, lightweight, human-safe robotic arm for low-force, long-distance, telerobotic ultrasonography. We undertook intercity and trans-Atlantic telerobotic ultrasound simulation from master stations located in New York, New York and Munich, Germany, and imaged a phantom and a human volunteer locate...

On the limited urban area, precise measurement of meteorological data is not easy for the cost problem. The facilities collecting the data require high installment costs. The mobile sources can be a solution in city region. For example, a public bus on which some meteorological sensors are installed can act as moving information gathering station. The information is gathered on a server and agg...
