This article describes two power mobility training protocols used with seniors and compares posttraining driving performance. Twelve users of power mobility were consecutively recruited from two residential facilities in Toronto, Canada. The aim of training at both sites was to make clients comfortable with and safe at driving power mobility devices. The content of training was similar, but tra...

This study investigates replication strategies for reducing latency to desired content in a vehicular peer-to-peer network. We provide a general constrained optimization formulation for efficient replication and study it via analysis and simulations employing a discrete random walk mobility model for the vehicles. Our solution space comprises of a family of popularity based replication schemes ...

an alternative in vitro approach to drug screening has been the use of human cell cultures for antiviral agents and microbial cell cultures for the assessment of the carcinogenic potential of selected compounds. a number of protozoan species have been also used as drug screens for anti-protozoal agents. the ciliated protozoan tetrahymena pyriformis species has been widely utilised as a drug scr...

background: in addition to macrovascular and along with other microvascular complications, diabetic patients suffer from some common musculoskeletal complications. the aim of this study was to assess the prevalence of five musculoskeletal disorders of upper extremity including shoulder capsulitis (sc), limited joint mobility (ljm), dupuytren’s contracture (dc), carpal tunnel syndrome (cts), and...

Lithium containing droplet and cluster targets irradiated by laser pulses are proposed as prospective source of for soft x-ray lithography. Analytical model and simulations show that laser with repetition rate of several MHz with energy of several mJ and pulse duration 10 ps is required.

We show that according to the GRB internal shock model the pulse duration and the interval between neighboring pulses are correlated and have a similar distribution. We analyze a sample of bright long bursts and find that the pulses duration have a lognormal distribution while the intervals has an excess of long intervals (relative to lognormal distribution). This excess can be explained by the...

The purpose of the study was to compare the mobility of selected joints of the limbs in diabetic and non-diabetics subjects. One hundred subjects comprising of 50 volunteer diabetics and 50 volunteer non-diabetics subjects participated in this study. The range of motion of the shoulder, elbow, wrist, fingers, hip and knee joins were measured using a double armed simple goniometer and recorded i...

The challenge of supporting rapidly growing numbers of mobile subscribers, while constrained by limited radio spectrum, is being met through increasingly smaller radio cells. This, however, results in increased signalling for location management procedures, which reduces the bandwidth available for user traffic. Location areas in current systems, such as GSM, consist of static and arbitrarily-d...

Using the nationally representative dataset of the 2007 Pakistan Time-Use Survey, this paper examines gender differences in daily trip rate, mode choice, travel duration, and purpose of travel, which are previously unreported because of limited data availability. Wide gender mobility gaps are observed in the country, where women are less likely to travel, are half as mobile as men and may rely ...

In this paper, we consider the use of our recently proposed Intra-Domain Mobility Management Protocol (IDMP) in generation (4G) mobile networks. On evaluating the heterogeneous access technologies, cellular layouts and application characteristics of 4G environments, we realize a need to reduce both the handoff latency and the frequency of mobility-related signaling. We first present IDMP’s fast...
