Motivated by the desire to assess nonpharmaceutical interventions for pandemic influenza, we seek in this study to quantify the routes of transmission for this disease. We construct a mathematical model of aerosol (i.e., droplet-nuclei) and contact transmission of influenza within a household containing one infected. An analysis of this model in conjunction with influenza and rhinovirus data su...

every digital transmission system requires frame alignment. it is necessary to identify the varius signal componets and to bring receiver into phase with respect to the transmission format so that the digits can be properly assembled for demultiplexing. fast and reliable frame alignmant is important, and therefore has been a subject for study. this paper a comprehensive analysis of frame alignm...

AIDS telephone hotlines have an important function in AIDS education, HIV prevention and counselling. In this study, consults of the Dutch AIDS information helpline were evaluated to determine the AIDS information needs of the callers and callers' satisfaction with the telephone-delivered information and consultation. Immediately after their telephone consult, callers (N = 309) were redirected ...

increasing amount of audiovisual (AV) content that is offered by web sites leads to a network bandwidth and storage capacity problem. Caching is one of the techniques that can ease this problem. But even in a caching system the distribution of data (i.e. the AV content) should be bandwidth-efficient. Furthermore the delivery to the end-user must regard the restrictions implied by real-time data...

this paper investigates the islands formation in initial stages of restoration process in blackout condition and studies the impacts of islands number variation on the process execution. in addition, a method is proposed to determining each island optimal boundaries. then the effects of transmission lines thyistor controlled series compensators (tcsc) to facilitate restoration process and impro...

This paper presents an image transmission control mechanism which – in contrast to existing systems – adapts dynamically to the capabilities of the client display as well as to the available transmission bandwidth. This mechanism is based on existing image compression algorithms whose strengths and weaknesses are summarised. For JPEG image compression, the predictability of the compression rati...

introduction: according to change in the approach to the rehabilitation of children with disability, function is an effective characteristic of the quality of life for these children. pediatric evaluation of disability inventory (pedi) was designed to assess the function of 6 months to 7 and half years old children. the aim of this study was to translate the pediatric evaluation of disability i...

The role of killer cell immunoglobulin-like receptors (KIRs) in the transmission of HIV-1 has not been extensively studied. Here, we investigated the association of KIR gene content polymorphisms with perinatal HIV-1 transmission. The KIR gene family comprising 16 genes was genotyped in 313 HIV-1 positive Kenyan mothers paired with their infants. Gene content polymorphisms were presented as pre...

A cloud and cache-aided wireless network architecture is studied in which edge-nodes (ENs), such as base stations, are connected to a cloud processor via dedicated fronthaul links, while also being endowed with caches. Cloud processing enables the centralized implementation of cooperative transmission strategies at the ENs, albeit at the cost of an increased latency due to fronthaul transfer. I...

In a study of the oxygen stores of the body anaesthetized paralyzed dogs were hyperventilated (Pa<x), = 15 mm Hg) for 2 hours. During the final 30 minutes the inspired mixture was altered from oxygen to air. The rates at which alveolar and arterial oxygen concentrations approached their new steady-state values were represented by the halftimes (t£) 0.17 and 0.23 minutes respectively. The turnov...
