Current data models like the NF 2 model and object-oriented models support set-valued attributes. Hence, it becomes possible to have join predicates based on set comparison. This paper introduces and evaluates two main memory algorithms to evaluate eeciently this kind of join. More speciically, we concentrate on subset predicates.

The PRISMA project is a large-scale research effort in the design and implementation of a highly parallel machine for data and knowledge processing. The PRISMA database machine is a distributed, main-memory database management system implemented in an object-oriented language that runs on top of a multi-computer system. A prototype that is envisioned consists of 64 processing elements.

Homodyne detection is proposed to increase the readout signal of bit-oriented holographic memories. It can be easily implemented on present memory architectures by making the diffracted signal interfere with a reflection of the reading beam. The large resulting increase of the readout signal can be used to enhance the data transfer rate. A first experimental demonstration of such a readout proc...

A novel memory-oriented OWL storage system is proposed. Semantic Web is recognized as the next generation Web and OWL (Web Ontology Language) is one of the most important technologies to achieve the Semantic Web. Even though several memory-oriented storage systems have been proposed to manage and handle OWL documents, they still suffer from low performance. In this paper, we propose a new memor...

The development of high-performance and lower power portable devices relies on both the underlying hardware architecture and technology as well as on the application software that executes on embedded processor cores. One way to confront the increasing complexity and decreasing time-to-market of embedded software is by means of modular and reusable code, forcing software designers to use object...

Given recent increases in the size of main memory in modern machines, it is now common to to store large data sets in RAM for faster processing. Multidimensional access methods aim to provide efficient access to large data sets when queries apply predicates to some of the data dimensions. We examine multidimensional access methods in the context of an in-memory column store tuned for on-line an...

Object-oriented techniques are shown to hold promise for addressing the growing speed gap between memory and processors on shared-memory multiprocessors. However, reducing cache misses can be at the expense of more misses from the translation lookaside buffer (TLB—a cache of recent page translations). This paper presents simulation results from use of a library called OOSH (Object-Oriented Libr...

The politics of memory World War II underlies the public and political discourses in contemporary Russia Serbia, with elites using narrative victory against fascism as a unifying legitimising tool. heroic war is also outward-oriented underpins ever-closer relations between two countries. This article explores how exports engages introducing concept diplomacy form diplomacy. Based on travelling ...
