A synthesis procedure for asynchronous control circuits from a high level speci cation signal transition graph STG is described In this paper we propose some syntactic constraints on STG to guarantee hazard free im plementation We have introduced a global persistency concept in order to establish the relationship between the persistency concept introduced by Chu which we call local persistency ...

Almost all groups involved in linear collider detector studies have their own simulation software framework. Using a common persistency scheme would allow to easily share results and compare reconstruction algorithms. We present such a persistency framework, called LCIO (Linear Collider I/O). The framework has to fulfill the requirements of the different groups today and be flexible enough to b...

Nonvolatile, byte-addressable memory (NVM) will soon be commercially available, but registers and caches are expected to remain transient on most machines. Without careful management, the data preserved in the wake of a crash are likely to be inconsistent and thus unusable. Previous work has explored the semantics of instructions used to push the contents of cache to NVM. These semantics compri...

The asymptotic behavior of a stage-structured predator-prey system is studied using the theory of finite dimensional competitive systems. Using natural conditions on the persistency constant for prey and on the reproduction rate of the mature predators, it is found that the system under consideration has a unique positive equilibrium, which is globally asymptotically stable. Some considerations...

In this paper, we provide an approach for modeling data variability as part of the overall software product line modeling approach. Modeling data variability in software product lines allows tailoring the data to the variability of a product. For this purpose, we have extended our Feature Assembly Modeling technique with the concept of persistency feature. We explain how these persistency featu...

Many protocols have been proposed to improve persistency and data availability in Collaborative Virtual Environments (CVEs). Two approaches have been proposed in the literature. Structured peer-to-peer network such as a distributed hash table (DHT) while the other approach uses an unstructured peer-to-peer network. With the rapidly increasing use of personal mobile devices, we are facing new op...

This paper proposes an information management system providing distribution and persistency. By separating context from virtual address space, our system has a uni ed approach for both distribution and persistency. The former is achieved by moving contexts between sites and the latter by moving contexts between virtual address space and persistent storage. Contexts include any information inclu...

The changes in egg production, in broodiness index and in plasma concentrations of LH, prolactin, oestradiol and progesterone were monitored throughout the first period of laying in turkey hens. The hens were subsequently classified according to their ability to express broodiness (33%) and their laying persistency; 25% were out-of-lay by the end of the experiment. A high percentage (67%) of th...
