The impact o f user mobi lity on network planning is investigated. For a ystem of tw o base station the stationary distribution o f a Markov chain, including mobility, is computed.

The ability of single-stranded DNA oligomers to form adjacent triplex and duplex domains with two DNA structural motifs was examined. Helix-coil transition curves and a gel mobility shift assay were used to characterize the interaction of single-stranded oligomers 12-20 nt in length with a DNA hairpin and with a DNA duplex that has a dangling end. The 12 nt on the 5'-ends of the oligomers could...

Aerial base stations (ABSs) have gained significant importance in the next generation of wireless networks for accommodating mobile ground users and flash crowds with high convenience quality. However, to achieve an efficient ABS network, many factors pertaining flight, governing laws information transmissions must be studied. In this article, multidrone communications are studied three major a...

A method is described for measuring the bandgap narrowing in the base of a Si homojunction or SiISiGe heterojunction bipolar transistor from the temperature dependence of the collector current. The model includes the temperature dependence of the intrinsic carrier concentration, the bandgap, the minority carrier mobility, and freeze-out of dopant in the base. The analysis method is applied to t...

with a cellular architecture of base stations, it is investigated that each wireless node can be realized with a throughput that By employing a practical and simple routing policy to study and analyse the capacity u s i n g m o b i l i t y and delay of an ad-hoc wireless network and consisting of static wireless nodes overlaid scales sub linearly or linearly with ., The analysis shows that one ...

OBJECTIVE To investigate the influence of the use of a rollator walking aid on assessment of gait and mobility. DESIGN Prospective, longitudinal study. SUBJECTS Geriatric patients during inpatient rehabilitation (n=109; mean age 83.1 years). METHODS Assessment at the beginning and prior to discharge from rehabilitation using: gait-analysis (GAITRite®, speed, cadence, stride-time, stride-l...

BACKGROUND Dementia impairs spatial orientation and route planning, thus often affecting the patient's ability to move outdoors and maintain social activities. Situation-aware deliberative assistive technology devices (ATD) can substitute impaired cognitive function in order to maintain one's level of social activity. To build such a system, one needs domain knowledge about the patient's situat...

The key role of water to obtain high-mobility IO:H (hydrogenated indium oxide) layers has been well documented, but introducing the required tiny amount of water is technologically challenging. We first use simulations to evidence the key role of high mobility for the transparent conductive oxide for high-efficiency crystalline silicon solar cells. Then, we investigate an approach to fabricate ...
