FOR MOST LAW ENFORCEMENT AND EMERGENCY SERVICES AGENCIES, THE costs related to the purchasing, equipping, operating and maintaining of fleets is the largest single recurring cost, outside that of personnel. The cost of acquiring vehicles, the costs associated with equipping and maintaining these vehicles, and escalating fuel costs have created difficulties for many departments— including police...

the first international convention on maritime transportation is thebrussels’ convention of 1924. this convention was widely acceptedthroughout the world and; thus, lasted for a long time due to the widespreadsupport of the countries possessing fleet for this convention and the lack ofexistence of a legal document in terms of maritime transportation. thepassage of time together with innovations...

Gate sizing is used to increase the performance and/or decrease the area and/or power dissipation of CMOS circuits. There has been extensive work on gate sizing introducing several different methods, producing mixed results in solving speed, size of benchmark circuits and accuracy. These papers however rarely make comparisons between solving methods and usually only use small benchmarks. We int...

The future of US transport energy requirements and emissions is uncertain. Transport policy research has explored a number of scenarios to better understand the future characteristics of US light-duty vehicles. Deterministic scenario analysis is, however, unable to identify the impact of uncertainty on the future US vehicle fleet emissions and energy use. Variables determining the future fleet ...

The impact of a potential future fleet of supersonic aircraft on contrail coverage and contrail radiative forcing is investigated by means of simulations with the general circulation model ECHAM4.L39(DLR) including a contrail parameterization. The model simulations consider air traffic inventories of a subsonic fleet and of a combined fleet of suband supersonic aircraft for the years 2025 and 2...

The adoption of hybrid-electric aircraft is expected to have a considerable impact on airport operations, with the need new infrastructural requirements support electric-powered fleets. In particular, battery-charging shall play decisive role. Preliminary investigations useful perform scenario studies for future implementation aviation can take advantage ARES methodology presented here, which p...

This paper describes a tabu search heuristic for a vehicle routing problem where the owner of a private fleet can either visit a customer with one of his vehicles or assign the customer to a common carrier. The owner's objective is to minimize the variable and fixed costs for operating his fleet plus the total costs charged by the common carrier. The proposed tabu search is shown to outperform ...

This paper describes a transistor sizing methodology for both analog and digital CMOS circuits. Various techniques are used for power optimization in CMOS VLSI circuits. Transistor sizing is one of the important techniques for the determination of circuit performance. The aim of the power optimization is to minimize the power and power-delay product or the energy consumption of the circuit. Thu...

To avoid both over-design and under-sizing of airport passenger terminal facilities such as security checkpoints, the infrastructure is designed for a specifically determined design load. As such, load considered short period time, usually an hour operation, during which peak, though not necessarily maximum, demand occurs. For strategic planning applications, future loads can be by either ficti...
