A particularly simple Markov chain model for a reference string is described. The model, which is only slightly more complicated than the independent reference model, generates strings that have a locality property and that have a specified probability distribution of references over pages. Expressions are obtained for expected working-set size and expected working-set miss ratio. The of change...

This paper proposes an adaptive invalidate/update protocol for software distributed shared memory(DSM), which use the working-set notion of a conventional operating system as the criteria for determining whether to update or invalidate. The proposed protocol can adjust the amount of update messages as changing the value of working-set size. The proposed protocol was implemented in CVM[4], a sof...

The article considers the international experience of legal regulation labor minors and identifies promising areas for improving current legislation Ukraine in field work minors. In particular, authors studied Latvian, Lithuanian, Slovak, Estonian Republics, Great Britain, provinces Canada (Alberta Manitoba).
 As you know, has certain features both other countries, given their physiologica...

We analyze the performance of E-limited scheduling in Bluetooth piconets under bursty traffic finite buffer case. We model joint probability distributions of uplink and downlink queues using the M [x]/G/1/K model with vacations and derive buffer blocking probabilities at slaves and at the master. We also derive access delays at slave uplink buffers. Analytical results are validated through simu...

We investigate Gaver’s parallel system attended by a cold standby unit and a repairman with multiple vacations. By analysing the spectral distribution of the system operator and taking into account the irreducibility of the semigroup generated by the system operator we prove that the dynamic solution converges strongly to the steady state solution. Thus we obtain asymptotic stability of the dyn...

In this paper, we demonstrate the impact of Multiword Expression (MWE) resources in the task of MWE recognition in text. We present results based on the Wiki50 corpus for MWE resources, generated using unsupervised methods from raw text and resources that are extracted using manual text markup and lexical resources. We show that resources acquired from manual annotation yield the best MWE taggi...

Nowadays, enterprises cooperate more extensively with other enterprises during the entire product life cycle. Temporary alliances between various enterprises emerge such as those in Virtual Enterprises. Collaborative applications are demanded that enable enterprises to engage in such endeavors. This paper aims to present a framework with which collaborative applications can be characterized and...
