In this paper, an identity-based key agreement system and its implementation for mobile telephony in GSM and UMTS networks is presented. The use of telephone numbers as public keys allows the system to piggyback much of the security overhead for key management to the existing GSM or UMTS infrastructure. The proposed approach offers solutions to the problems of multi-domain key generation, key d...

Since the first observations that the numbers of circulating CD34+ progenitor cells are increased in patients with coronary artery disease and after myocardial ischaemia and are associated with a better cardiovascular outcome, a plethora of mechanisms have been proposed to explain their potential beneficial effects and investigate their therapeutic usage. Along with the rather improbable potent...

Recent reports on microcoils are reviewed. The first part of the review includes a discussion of how the geometries of the sample and coil affect the NMR signal intensity. In addition to derivation of the well-known result that the signal intensity increases as the coil size decreases, the prediction that dilution of a small sample with magnetically inert matter leads to better sensitivity if a...

Electronic fuel injection (EFI) is a complex system, many parts are connected together from mechanical to electronic control the internal combustion engine. It must ensure different works and most important thing in motorsport achieve power optimization. High engine responsiveness often desired gain competitive edge. Usually enthusiast will upgrade car standard with aftermarket components such ...

This paper first defines a novel spatial-temporal coverage metric, k-depth coverage, for mobile crowdsensing (MCS) problems. This metric considers both the fraction of subareas covered by sensor readings and the number of sensor readings collected in each covered subarea. Then iCrowd, a generic MCS task allocation framework operating with the energy-efficient Piggyback Crowdsensing task model, ...

Distributed Hashtables (DHT) are intended to provide Internet-scale data management. By following the peer-to-peer paradigm, DHT consist of independent peers and operate without central coordinators. Consequentially, global knowledge is not available and any information have to be exchanged by local interactions between the peers. Beneath data management operations, a lot of meta-data have to b...
