WSN can have a node scheduling based on partition. Employment of such technique can reduce energy consumption of wireless sensor nodes and prolong the network lifetime. Firstly the monitoring area was partitioned into equal virtual grid, according to which the algorithm has two working mode one is monitoring mode and other one is tracking mode. In case of former only one node worked in each gri...

In [4, 13], Bancilhon and Paredaens introduced a notion of completeness for relational database languages on instance-level. Their criterion was subsequently called BP-completeness. Since then, it was used frequently in the context of other database models. However, its application in the context of languages involving object creation appears to raise some serious problems. In this paper, we us...

As opposed to contemporary activity-centric, process-aware information systems (PAIS), for which a multitude of concepts and implementations exist, there is only a very limited number of PAIS implementing data-centric, artifact-centric or object-aware approaches. This demo paper presents the implementation of a modeling environment for the object-aware approach to business process management. O...

From a sample of about 10 φ mesons produced at DAΦNE, we have selected KL mesons tagged by observing KS → ππ decays. We present results on the major KL branching ratios, including those of the semileptonic decays needed for the determination of |Vus|. These branching ratio measurements are fully inclusive with respect to final-state radiation. The KL lifetime has also been measured.

OBJECTIVE To compare the cost effectiveness of the three most commonly chosen types of prosthesis for total hip replacement. DESIGN Lifetime cost effectiveness model with parameters estimated from individual patient data obtained from three large national databases. SETTING English National Health Service. PARTICIPANTS Adults aged 55 to 84 undergoing primary total hip replacement for oste...

the parallel systems are special important types of coherent structures and have many applications in various areas.in this paper we consider a two-exchangeable-component parallel system for the generalized farlie-gumbel-morgenstern (generalized fgm) distribution. we study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...

OBJECTIVE To define risk thresholds for cost-effectiveness of risk-reducing salpingo-oophorectomy (RRSO) for ovarian cancer (OC) prevention in low/intermediate risk postmenopausal women. METHODS A decision-analytic model compares lifetime costs-&-effects of offering 'RRSO' with 'no RRSO' to postmenopausal women ≥50years for different lifetime OC-risk thresholds: 2%, 4%, 5%, 6%, 8% and 10%. We...

(FBRs). The factors influencing fatigue lifetime in sodium compared with that in air were investigated by observation of surface cracks in 316FR steel. Furthermore, the effects of sodium environment on fatigue were investigated based on examining the results of thermal striping tests, etc., obtained up to now. The results of the fatigue tests show that many micro cracks in the shearing directio...

This paper discusses the CRISTAL object lifecycle management system and its use in provenance data management and the traceability of system events. This software was initially used to capture the construction and calibration of the CMS ECAL detector at CERN for later use by physicists in their data analysis. Some further uses of CRISTAL in different projects (CMS, neuGRID and N4U) are presente...

Saving energy is a very critical issue in wireless sensor networks (WSNs) since sensor nodes are typically powered by batteries with a limited capacity. Since the radio is the main cause of power consumption in a sensor node, transmission/reception of data should be limited as much as possible. To this aim, we propose a novel distributed approach to data aggregation based on fuzzy numbers and w...
