We present nameless writes, a new interface that obviates the need for indirection in modern solid-state storage devices (SSDs). Nameless writes allow the device to pick the location of a write and only then inform the client above of the decision. Doing so keeps control of block allocation decisions in the device, thus enabling it to perform important tasks such as wear-leveling, while removin...

The relative motion between an earth-based radar and a satellite object is of interest for radartracking studies, signature simulation studies, and for developing inverse scattering techniques. Here, the motion analysis is accomplished with elementary vector algebra. This approach results in considerable simplification of the final equations and relation ships. REVIEW AND APPROVAL This technica...

In this paper, chance-constrained 0–1 integer programming models for the stochastic traditional and U-type line balancing (ULB) problem are developed. These models are solved for several test problems that are well known in the literature and the computational results are given. In addition, a goal programming approach is presented in order to increase the system reliability, which is arising f...

A comparative study has been carried out on performance of two-dimensionally reinforced carbon/ phenolic (C/P) and carbon/epoxy (C/E) composites, subjected to low amplitude reciprocating wear at different temperatures. The C/P composite has shown greater wear rate than the C/E composite, with the difference being modest at room temperature, and larger at 250 °C. The values of coefficient of fri...

Production leveling (heijunka) is one of the lean tool that is used to stabilize a manufacturing system (reduce the bullwhip effect). Production leveling is a kind of cyclic scheduling that creates production regularity and coordination simplicity. This article describes simulation modeling and multivariate analysis of an assembly production line in a microelectronics factory. The assembly line...

The primary objective of this paper is the evaluation of the InSAR derived displacement field caused by the 07/09/1999 Athens earthquake, using as reference an external data source provided by terrestrial surveying along the Mornos river open aqueduct. To accomplish this, a processing chain to render comparable the leveling measurements and the interferometric derived measurements has been deve...

This paper presents linear programming (LP) formulations for short-term energy time-shift operational scheduling with energy storage systems (ESSs) in power grids. In particular, it is shown that the conventional nonlinear formulations for electric bill minimization, peak shaving, and load leveling can be formulated in the LP framework. New variables for the peak and off-peak values are introdu...
