ôbjective: â rare phenomenon of shared psychosis disorder occurring in the context of bipolar ï disorder, in identical twins is reported. çase presentation: two identical twins with shared psychotic manic syndrome were admitted and received antipsychotic and lithium as their treatment. psychotic symptoms of primary case did not improve and her diagnosis changed into schizophrenia. they had hypo...

The need for user-defined execution orders (or control structures) for rules is well recognized by researchers of active database management systems. Priority-based approaches (e.g., numeric priorities) have been used to specify a desired control structure among rules. However, due to the fact that fixed priorities are assigned to rules, independent of different contexts in which they may be tr...

In this paper we describe an extension of the LOTEC (Lazy Object Transactional Entry Consistency) protocol designed to minimize the network traffic required to maintain consistency in a software-only DSM (Distributed Shared Memory). Unlike traditional DSM systems which are targetted for shared memory parallel computing, the protocols discussed in this paper are designed to support distributed p...

It is more important to optimize the distributed system features to obtain the maximum possible performance. A distributed shared memory (DSM) of distributed system is kind of mechanism that allowing system’s multiple processors to access shared data without using interposes communication(IPC). A DSM is a simple yet powerful paradigm for structuring multiprocessor systems. It can be designed us...

52 Abstract— Most of the algorithms that exist today for concurrency control over distributed shared memory, either fail to provide a scalable model or involve a large communication overhead for establishing consensus over the state of the shared variables. After a thorough study of some of the efficient algorithms this field, this paper introduces a functional view of a holistic approach, whic...

Global locality optimization is a technique for improving the cache performance of a sequence of loop nests through a combination of loop and data layout transformations. Pure loop transformations are restricted by data dependences and may not be very successful in optimizing imperfectly nested loops and explicitly parallelized programs. Although pure data transformations are not constrained by...

The abstraction of a centralized memory which has been successfully introduced in shared memory Multiprocessors has also been adopted for Distributed Shared Memory (DSM) in loosely coupled, network-based distributed systems as an adequate paradigm to handle shared state. In this paper a concept for a resilient distributed shared memory is elaborated which takes advantage of an advanced action m...

! Distributed computer system is a set of autonomous computers connected by a network of transmission channels and equipped with a distributed system software. This is a work environment for a class of tasks of common objective; the network is a communication infrastructure only. Main features of distributed systems dealt with here are: • absence of common clock for all computers – no global ti...

Robotically Augmented Electric Guitar is a novel robotic guitar that establishes shared control between human performers and mechanical actuators. Unlike other mechatronic guitar instruments that perform pre-programmed music automatically, this guitar allows the human and actuators to produce sounds jointly; there exists a distributed control between the human and robotic components. The intera...

We claim that the renting of machine resources on clusters of servers introduces new systems challenges which are different from those hitherto encountered, either in multimedia systems or cluster-based computing. We characterize the requirements for such “public computing platforms” and discuss both how the scenario differs from more traditional multimedia resource control situations, and how ...
