The aging of the population in developed and developing countries calls for special attention to improve the quality of life for older people. Meanwhile, one of the key factors influencing the quality of life of older people is their mobility. Most of the previous studies have considered the mobility of younger people while considering the aging of the population, the mobility of older people n...

We develop a multi-patch and multi-group model that captures the dynamics of an infectious disease when the host is structured into an arbitrary number of groups and interacts into an arbitrary number of patches where the infection takes place. In this framework, we model host mobility that depends on its epidemiological status, by a Lagrangian approach. This framework is applied to a general S...

Using a configuration-space approach, this paper develops a novel 2nd-order mobility theory for rigid bodies in contact. A major component of this theory is a coordinate invariant 2nd-order mobility index for a body, B, in frictionless contact with finger bodies A1; ;Ak. The index is an integer that captures the inherent mobility of B in an equilibrium grasp due to second order, or surface curv...

Spatial mobility is a topical concept of analytical migration science, which makes it possible to assess the desires, readiness and capabilities of the population to move over certain distances and time. In the management of spatial mobility assessment requires the organization of systematic monitoring, which includes identifying the mobility potential in spatial and temporal interpretation, th...

Mobility management of Internet nodes has been widely investigated over the last few years. Various schemes have been developed to support mobility in the Internet. While designing mobility management schemes, a few fundamental considerations have to be followed to achieve better performance. In this paper, we present a number of important issues that have to be considered while designing mobil...

Abstract-Silicon, the main material of microelectronics, is perfectly suited for spin-driven applications. All-electrical spin injection in silicon has been demonstrated, however, the magnitude of the corresponding signal is larger than theoretically predicted. We analyze the influence of electrostatic charge screening on the efficiency of spin injection at the ferromagnet-semiconductor interfa...
