Solid-state drives (SSDs) are quickly becoming the default storage medium as the cost of NAND flash memory continues to drop. However, flash memory introduces new challenges, as data cannot be efficiently updated in-place. To overcome the technology’s limitations, SSDs incorporate a software Flash Translation Layer (FTL) that implements out-of-place updates, typically by storing data in a log-s...

The task of seeking alternatives to a classification system such as DSM-II that will maximize its benefits and minimize its limitation is a complex and arduous one. There are no clear-cut answers. Certain issues had been elaborated on here. The task at hand is one that must be approached on a multiprofessional basis seeking to integrate a variety of theoretical bases into a functional conceptua...

In topology-based localization, each node in a network computes its hop-count distance to a finite number of reference nodes, or “landmarks”. This paper studies the impact of landmark placement on the accuracy of the resulting coordinate systems. The coordinates of each node are given by the hop-count distance to the landmarks. We show analytically that placing landmarks on the boundary of the ...

The aim of this paper is to identify the key factors that lie behind venture capital/private equity fundraising in countries where there is scarce and asymmetric information about final returns. The main contribution of this paper is to explain fundraising by means of variables directly related to the venture capital process rather than by macroeconomic ones. We use panel data techniques on dat...

introduction: the aim of this in vitro study was to evaluate the effect of calcium hydroxide (ch) on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture (cem) cement in simulated furcation perforations. methods and materials: furcation perforations, measuring 1.3 mm in diameter and 2 mm in height, were created in 80 human mandibular first molars. the t...

Video applications are characterized by their increased requirements for huge storage spaces and timing synchronization. Video data storage is a critical issue due to the so-called I/O bottleneck problem in relation to the quality of service while accessing video applications. The main contribution of the paper is that it considers video data dependencies, access frequencies and timing constrai...

Distributed multimedia systems and applications are characterized by their strong requirements for huge storage spaces and timing synchronization to meet clients demands. Therefore, multimedia data storage has become a critical issue in relation to the Quality of Service (QoS) of multimedia applications. This paper introduces a popularity-based model where multimedia(video) data representation ...
