Time and frequency characterization of precision clocks and oscillators is an important task in the maintenance of time and frequency standards. Recently, time domain signal characterization of clocks is generally preferred and several pedormance measures of clocks and oscillators are defined in ITU-T Recommendation G.810. Among these measures, Maximum Time Interval Error (MTIE), Time Deviation...

We propose an opportunistic channel access scheme for cognitive radio-enabled secondary networks. In our work, we model the channel occupancy due to Primary User (PU) activity as a 2-state Alternating Renewal Process, with alternating busy and idle periods. Once a Secondary Node (SN) senses the channel idle, the proposed scheme uses the residual idle time distribution to estimate the transmissi...

The Share algorithm for predicting disk idle time described by Helmbold, et al was implemented and run on the cello1 dataset. As in the original paper, the share algorithm performed slightly better than the 2-Competitive algorithm and a lot better than the 30-second Fixed Time-Out algorithm. As expected, the Share algorithm performed worse than the Optimal algorithm. It was determined that vary...

In the framework of perfect loop nests with uniform dependencies, tiling has been studied extensively as a source-to-source program transformation. We build upon recent results by HH ogsted, Carter, and Ferrante 10], who aim at determining the cumulated idle time spent by all processors while executing the partitioned (tiled) computation domain. We propose new, much shorter proofs of all their ...

We study options on short-term leases for capital-intensive equipment performing specific functions and services, such as leases for semi-submersible drilling rigs, marine seismic services, corporate real estate leasing, retail space leasing, and apartment leasing. We quantify the effect of an important factor in pricing options on these services: idle time between consecutive lease contracts. ...

This paper considers the single machine scheduling problem with linear earliness and quadratic tardiness costs. The research on the version with inserted idle time focused on an exact approach, while several heuristics had already been proposed for the version with no idle time. These heuristics were then the basis for the development of new heuristic procedures for the version with idle time. ...

In order to lowering level of emissions of internal combustion engines (ICEs), they should be optimally controlled. However, ICEs operate under numerous operating conditions, which in turn makes it difficult to design controller for such nonlinear systems. In this article, a generalized unique controller for idle speed control under whole loading conditions is designed. In the current study, in...
