INFORMATION DISCOVERY IN DISTRIBUTED SYSTEMS A NOVEL
CONCEPT BASED ON MODELLING OF INFORMATION ELEMENTS




ABSTRACT
Sharing of information with those in need of it has always been an idealistic goal of networked environments. With the proliferation of computer networks, information is so widely distributed among systems, that it is imperative to have well-organized schemes for retrieval and also d ....etc

Due to innovations in sensor technology and rising complexity of manufacturing processes, increasingly more sensors are distributed throughout manufacturing and production systems to maintain the production performance, to ensure the life-cycle quality of products, and to improve the quality of management and service. This system-wide deployment of sensing devices is referred to as a distributed sensor system. Distributed sensor systems have resulted in a data-rich manufacturing environment and provide us unprecedented opportunities for quality ....etc

Mobile Agents In Distributed Multimedia Database Systems
Abstract: The size of networks is increasing rapidly and this fact is not straitened to the internet alone. Many intra and inter“organization networks are affected by this trend, too. A side effect of this growth is the increase of network traffic. This development leads to new challenges and we have to think about new technologies. Mobile agent systems are one answer to these challenges. Mobile agents are an emerging technology attracting interest from the fields of distribute ....etc

UNIT “ II
COMMUNICATION AND INVOCATION:-
Communication is not an end in it-self, but is normally part of the
implementation. Such as a remote procedure call, whose purpose is to
bring about the processing of data in a different scope of execution
environment?
Application imposes a variety of demands upon a communication
system. These include procedure-consumer, client-server and group
communication. They vary as to the quality of service required, that is
delivery guarantees, bandwidth the latency, ....etc

Analysis and Design Methods of Distributed Sensor Systems for Manufacturing Quality Improvement



Due to innovations in sensor technology and rising complexity of manufacturing processes, increasingly more sensors are distributed throughout manufacturing and production systems to maintain the production performance, to ensure the life-cycle quality of products, and to improve the quality of management and service. This system-wide deployment of sensing devices is referred to as a distributed sensor system. Distributed sensor systems have ....etc

Distributed-Input-Distributed-Output (DIDO) Wireless Technology



Abstract

Distributed-Input-Distributed-Output (DIDO) wireless technology is a breakthrough approach that allows each wireless user to use the full data rate1 of shared spectrum simultaneously with all other users, by eliminating interference between users sharing the same spectrum. With conventional wireless technologies the data rate available per user drops as more users share the same spectrum to avoid interference, but with DIDO, the data ....etc

One can define a distributed system as a system in which components located in networked computers communicate and coordinate their actions only by passing messages. So, the main challenge in making a distributed system is the heterogeneity of the components, their security, concurrency of components and transparency. To meet up with this challenge the Object Management Group (OMG) came up with an architecture called CORBA (Common Object Request Broker Architecture) in 1991. As the name suggests CORBA is not ....etc

Abstract :

Current trends in computing technologies are drifting towards distributed and parallel computing. These topologies emphasize on concurrent access schemes. Because of distributed computing, the use of shared resources like databases, memory, etc. is growing. Locking mechanisms can be used effectively to achieve high concurrency levels without corrupting the resources. There are a wide range of synchronization protocols, some providing strong consistency while others granting weak consistency. There is a trade-off between complexi ....etc
