Global mobility networks provide effective global roaming services for personal communication users. Through the universal roaming technology, legitimate mobile users can enjoy the ubiquitous services. Mutual authentication and key agreement between mobile users and roaming servers is the primary security issue of many commercial mobile networks. For personal privacy, it becomes an important is...

The reaction Cl + isobutene (i-C4H8) was reported by Suits et al. to proceed via, in addition to abstraction, an addition-elimination path following a roaming excursion of Cl; a near-zero translational energy release and an isotropic angular distribution observed at a small collision energy characterized this mechanism. We employed a new experimental method to further characterize this roaming ...

Multi-task learning has gained popularity due to the advantages it provides with respect resource usage and performance. Nonetheless, joint optimization of parameters multiple tasks remains an active research topic. Sub-partitioning between different proven be efficient way relax constraints over shared weights, may partitions disjoint or overlapping. However, one drawback this approach is that...

A model Hamiltonian for the reaction CH4(+) -> CH3(+) + H, parametrized to exhibit either early or late inner transition states, is employed to investigate the dynamical characteristics of the roaming mechanism. Tight/loose transition states and conventional/roaming reaction pathways are identified in terms of time-invariant objects in phase space. These are dividing surfaces associated with no...

High tier wireless systems such as GPRS and UMTS provide users high mobility but less bandwidth. On the other hand, low tier wireless systems such as Wireless LAN offer high bandwidth with less mobility. To support seamless roaming between heterogeneous wireless networks is regarded as one of the key issues in the future mobile communication system. The paper presents method and system for seam...

OBJECTIVES To describe the characteristics of unowned, free-roaming cats and their caretakers who participated in a trap-neuter-return (TNR) program and to determine the effect of the program on free-roaming cat colonies. DESIGN Prospective study. SAMPLE POPULATION 101 caretakers of 920 unowned, free-roaming cats in 132 colonies in north central Florida. RESULTS Most (85/101; 84%) caretak...

Bluetooth is a standard for wireless personal area networks. The current standard does not support roaming between different bluetooth networks. In this paper, we will introduce potential roaming techniques for data transfer scenarios using Bluetooth hardware devices and present a corresponding UML model.
