Optimized Profile Descent (OPD) is an arrival procedure for the Next Generation Air Transportation System (NextGen), which has been demonstrated to effectively decrease noise, emissions and fuel costs. Reference [1] identifies optimal sequencing and spacing policies for OPD operations under uncertainty and shows that the use of these policies at given metering points is expected to result in po...

Ramp metering has been broadly accepted and deployed as an effective countermeasure against both recurrent and non-recurrent congestion on freeways. However, many current ramp metering algorithms tend to improve only freeway travels using local detectors' inputs and overlook the negative impacts on local streets. This may generate two problems: 1) the optimal local settings may not result in a ...

Naor and Pinkas introduced metering schemes at Eurocrypt '98 in order to decide on advertisement fees for web servers. In the schemes, any server should be able to construct a proof to be sent to an audit agency if and only if it has been visited by at least a certain number, say k, of clients. This paper rst shows an attack for their schemes such that only two malicious clients can prevent a s...

As a result of recent changes in the policy governing internet content distribution, such as the institution of per listener royalties for internet radio broadcasters, Content Distributors (CDs) now have an incentive to underreport the size of their audience. Existing metering protocols protect only against the inflation of audience size. We introduce the first protocols for audience metering t...

One of the main characteristics of on demand computing in general and of utility computing services in particular is the “pay-as-you-go” model. To implement this model, one needs a flexible way to meter the services and resources being used. The UMI (Universal Management Infrastructure) architecture, designed to provide common functions that are needed by most, if not all, of the utilities in a...

A metering scheme is a method by which an audit agency is able to measure the interaction between servers and clients during a certain number of time frames. Naor and Pinkas 7] considered schemes in which any server is able to construct a cryptographically secure proof if and only if it has been visited by at least a number, say h, of clients in a given time frame. In this paper we construct me...

A new ramp metering strategy implemented on the Twin Cities freeway system to reduce ramp waiting times was evaluated through microsimulation of freeway activity. The study compared Stratified Ramp Metering strategy with the previous Zone Metering Strategy and with no control strategy. Comparison with Zone, which was designed to favor freeway flow, showed the new strategy succeeded in greatly r...

Since the advent of the law 86/14 concerning the exploitation of the national territory by foreign companies in partnership with the Algerian oil and gas company, the problem of hydrocarbons metering in the sharing production come out. More generally, good management counting hydrocarbons can provide data on the production wells, the field and the reservoir for medium and long term planning, pa...

We consider an environment in which many servers serve an even larger number of clients (e.g. the web), and it is required to meter the interaction between servers and clients. More speciically, it is desired to count the number of clients that were served by a server. A major possible application is to measure the popularity of web pages in order to decide on advertisement fees. The metering p...

Mechanically driven seed metering devices currently perform their function efficiently and are a good solution to the problem of metering rates as seed is planted, but there are many voids that could be filled with a substantial change to the metering process. Electronically controlled seed singulation devices can address many of the inefficiencies experienced in a mechanically driven seed mete...
