The duration of the holding time (dwell-time) in cellular telephony systems is a fraction of the total call duration due to the handoff mechanism. Some elements such as the mobility and cell shape and size will cause the dwell-time to have a probability distribution function different to that of the call duration, being the difference greater for higher mobility and smaller cell sizes (the limi...

DYOPTYKA’s innovative solution for the reduction of speckle noise in projection displays, using a phase randomizing deformable mirror, is shown to achieve good performance both within a single 1 μs pulse duration and through sequences of such pulses.

AIM The purpose of this study was to compare the clinical and subjective oral health indicators of type 2 diabetic patients (T2DM) with age and gender matched non-diabetic controls. A second aim was to identify clinical and subjective oral health indicators that discriminate between well-controlled and poorly controlled T2DM patients as well as between patients with long and short duration of t...

This article investigates the effects of homeownership on labour mobility and unemployment duration. We distinguish between finding employment locally or being geographically mobile. We find that homeownership hampers the propensity to move for job reasons, but improves the chances of finding local jobs, which is in accordance with the predictions from our theoretical model. The overall hazard ...

Mobile grids are one of the emerging grid types. They help to pool the resources of several cooperative mobile devices to resolve a computationally intensive task. Mobility management is a key challenge in mobile grids which includes mechanisms to track and maintain the locations of mobile nodes. Mobility prediction is one of the most important components of mobility management, which defined a...

The mobility of Cu, Pb and Zn in harbour sediments was investigated using single, sequential and kinetic extraction techniques. Each type of extraction provides different information on the mobility of these elements in the environment. The single HCl extraction assesses general mobility, the sequential extraction assesses geochemical partitioning and kinetic extraction allows quickly and slowl...

This paper studies housing tenure and labour mobility using individual data from the ECHP for five European countries. First, the effect of housing tenure on the unemployed workers’ labour mobility is studied using a discrete unemployment duration model with two alternative exits to employment, depending on whether they are associated with a residential change or not. Ownership is found to affe...
