In this paper we design some characteristics of a possible E-governance system for the urban mobility. In particular we shortly present the complex city features and the background automata gas paradigm for a microscopic modeling. Moreover we show some statistical laws based on long time series of traffic dynamics data, fundamental for the now-casting and the private vehicles mobility control. ...
We argue that separation of concerns can be advantageously applied to the development of applications relying on coarse-grained strong mobility, i.e. distributed applications moving entities while these entities are executing. We present the design of an infrastructure for such mobile applications where the mobility concern is cleanly separated from other concerns. We present an overview of a p...
Human migration is a type of human mobility, where a trip involves a person moving with the intention of changing their home location. Predicting human migration as accurately as possible is important in city planning applications, international trade, spread of infectious diseases, conservation planning, and public policy development. Traditional human mobility models, such as gravity models o...
Ad hoc networks are gaining increasing popularity in recent years because of their ease of deployment. No wired base station or infrastructure is supported, and each host communicates one another via packet radios. In ad hoc networks, routing protocols are challenged with establishing and maintaining multihop routes in the face of mobility, bandwidth limitation and power constraints. In this pa...
The understanding of human mobility patterns is key for the development and evaluation of ubiquitous applications. To overcome the scarcity and difficulties in capturing mobility data, models have been devised. In general, each model replicates some of the observed metrics, while neglecting others. However, all tend to ignore diversity, in the roles and goals of the users but also in the device...
OBJECTIVE To describe development of mobility and self-care capabilities in young children (aged 1-4 years) with cerebral palsy, and to examine whether the development of mobility and self-care capabilities differs by cerebral palsy severity in terms of 5 distinct Gross Motor Function Classification System (GMFCS) levels. STUDY DESIGN This prospective longitudinal cohort study included 100 ch...
BACKGROUND Change of job could be a strategy in vocational rehabilitation when return to the original job is not possible, but research is very limited concerning the effects of job mobility on the future vocational situation. The aim of the study was to investigate whether job-to-job mobility affects the likelihood of remaining on the labour market over time among persons who are employed and ...
Hyporheic flow in streams has typically been studied separately from geomorphic processes. We investigated interactions between bed mobility and dynamic hyporheic storage of solutes and fine particles in a sand-bed stream before, during, and after a flood. A conservatively transported solute tracer (bromide) and a fine particles tracer (5 μm latex particles), a surrogate for fine particulate or...
The effect of prior air exposure on rupture life of superalloys is reported. Oxygen is identified as a damaging species leading to severe losses in both rupture life and ductility. Similar embrittlement is observed in pure nickel and a mechanism is proposed in terms of reduced grain boundary mobility. Two cobalt base alloys and an oxide dispersion strengthened nickel base alloy do not embrittle...
Backbone connectivity is a critical and challenging problem in vehicle ad hoc networks. Just like base stations in cellular networks, the backbones or mobile base stations in vehicle ad hoc networks play important roles in location management and engineering applications. In this paper, we discuss the one-to-one connectivity by extending the navigation functions, and present the integrated powe...
