An area that has recently received attention from the distributed systems community is Swarm Intelligence (SI)---SI has been successfully used in fields such as robotics and optimisation. Recently its properties have started to attract research in distributed systems. In this paper we merge SI concepts into the LINDA model to provide an adaptive approach to time which is unrelated to external (real) time: the result ...

This paper addresses the opportunities for, and effects of, incorporating object attributes in Linda-like tuple-space systems. The focus is on exploring how the coordination attributes are affected by this enhancement, and investigating in what ways the classical Linda model ...

Although the concept of location abstraction is important, and eases the programming task, it is incomplete in the Linda case. Whenever I/O operations are necessary, users have to be aware of the locations of devices. The use of computational language specic details for distributed I/O restricts the portability of Linda programs. Hitherto Linda has shown us how to write portable distributed algorithms for a variety of applications but for applications involving I/O the portability is compromised. In order to achieve maximum portability, a Linda application has to access I/O using proper Linda facilities. This paper describes a generalisation of Linda that includes coordination of distributed I/O. The advantages of such a generalisation and the problems involved in the implementation are also discussed.

Technological advances more and more facilitate an access to knowledge in an anytime, anywhere, and anyhow manner. The provision of accurate knowledge with respect to a requester's context gets more challenging. Explicit coordination of knowledge can be one means to address such developments. This report summarises several works and discussions on the topic of Coordination of Knowledge in Pervasive Environments, highlights current research directions, and outlines potential future challenges.

Spontaneous bowel hernias are even rarer. Here, we present the first reported case of a combined spontaneous herniation of both the lung and bowel following an attack of acute bronchitis and coughing together with a description of surgical approach and repair.

Therefore, it is important to create a flexible architecture that allows a customer to choose the appropriate amount of fault tolerance, a concept we call" RAS by the yard." In this paper we describe a ...

An experimental arrangement of such technique involved making use of a novel temperature sensor coupled with an experimental test rig. The CST technique was found to be novel, simple, and reliable for velocity profile measurements of flowing polymer melts. The preliminary results showed that the velocity profiles in the barrel changed continuously with changing screw position.

It is shown that the platform extends without change of slope from Palaeozoic rocks onto Cretaceous, Oligocene and (?)Miocene beds. Five regressions and transgressions can be traced, and a tentative explanation is advanced for the slow transgression phases.

The assessment of environmental risks associated with genetically engineered baculovirus pesticid... more The assessment of environmental risks associated with genetically engineered baculovirus pesticides depends on an accurate knowledge of the host range of each virus. However, studies of baculovirus host ranges based solely on symptomology may misidentify as nonhosts any species with symptomless infections. This project used recombinant viruses that allowed detection of symptomless as well as pathogenic virus infections. Seven recombinant isolates of Autographa californica nuclear polyhedrosis virus (AcMNPV), Bombyx mori nuclear polyhedrosis virus, Lymantria dispar nuclear polyhedrosis virus (LdMNPV), and Orgyia pseudotsugata nuclear polyhedrosis virus were tested by either hemocoelic injection or per os inoculation for their potential replication in 23 insect species from eight orders and 17 families. The recombinant viruses contained genes coding for b-galactosidase, secreted alkaline phosphatase (SEAP), or luciferase under the transcriptional control of either the polyhedrin or ETL promoter. Replication was initially assessed based on detection of the reporter gene products. Results obtained with b-galactosidase or SEAP as indicators were more consistent but less sensitive than those with luciferase. With all insects tested, much higher reporter enzyme activities were found with the b-galactosidase reporter gene placed under the polyhedrin promoter than under the ETL promoter. As indicated by reporter enzyme activity after injection with the budded virus particles, the AcMNPV replicated in more species than did the other viruses, and the LdMNPV was the most host specific. Most of the insect species tested did not support detectable replication of any of the viruses. While an observation of symptoms of viral infection was usually concurrent with detection of reporter gene activities, with certain insect/ virus combinations, little or no reporter gene activity was detected even though the feeding activity and growth rates were significantly reduced relative to those of the sham-injected controls. The results of this project provide a database for the establishment of future environmental risk assessment protocols and guidelines with baculovirus pesticides.
