For ten years researchers have been attempting to construct programming language systems that support orthogonal persistence above conventional operating systems. This approach has proven to be poor; researchers invariably construct a complete abstract machine above the operating system with resulting loss of efficiency. This paper describes a new approach, the construction of an operating system designed to support orthogonal persistence. The operating system, Grasshopper, relies upon three powerful and orthogonal abstractions: containers, loc ....etc

Abstract
This paper describes Grasshopper, an operating system designed to provide generic mechanisms capable of being tailored to support a wide range of persistence paradigms. A constraint placed on this design is that the system must be implementable on conventional architectures which support paged virtual memory. In this paper the basic system abstractions relating to addressing environments, processes, and protection are described. It is shown that these provide explicit support for distributed persistent objects and processes, stabilit ....etc

INTRODUCTION
Computer environments have changed dramatically in recent years, from the large centralised mainframe to the networked collections of workstation style machines. The power of workstations is increasing, but the common paradigms used to manage data on these workstations are still fundame ....etc

Abstract
Various techniques have been developed for different query types in content-based image retrieval systems such as sampling queries, constrained sampling queries, multiple constrained sampling queries, k-NN queries, constrained k-NN queries, and multiple localized k-NN queries. In this seminar , propose a generalized query model suitable for expressing queries of different types, and investigate efficient processing techniques for this new framework. We exploit sequential access and data sharing by developing new storage and query p ....etc
