This paper presents a Real-time Upcall (RTU) [1] based TCP/IP implementation that guarantees throughput for continuous media applications and ensures low latency bounds for interactive applications. RTU is an endsystem rate-based scheduling mechanism that provides quality of service (QoS) in terms of CPU cycles, to applications. We restructured the existing NetBSD TCP/IP implementation to explo...

The digital medical images in real world are intensity images that carry less information, more noise, less resolution and poor illumination levels. In such cases the existing retrieval system fails in retrieving the relevant images. This is because the chosen similarity features in those systems are not effective for the above types of image retrieval. To address these issues the present paper...

PURPOSE The global incidence of cancer is rising, particularly in low- and middle-income countries. Radiotherapy is an important cancer treatment in the curative and palliative setting. We aimed to estimate the global demand for and supply of radiotherapy megavoltage machines (MVMs) and assess the changes in supply and demand during the past decade. MATERIALS AND METHODS Cancer incidences for...

All signals were transmitted between the primary plant and the protection and control system by means of hard-wired secondary cabling. Protection and control panels located in control rooms were equipped with protection relays, panel mimics and control switches. The primary plant and protection and control panels were hard-wired to a supervisory remote terminal unit (RTU) via a supervisory junc...

BACKGROUND Myocardial ischemia creates abnormal electrophysiological substrates that result in life-threatening ventricular arrhythmias. Identifying patients at risk of such abnormalities by use of body surface electrical measures is controversial. We investigated the sensitivity of torso measures, recorded simultaneously with epicardial electrograms, to changes in dispersion of depolarization ...

BACKGROUND The study arose as part of a best-practice nutrition model regarding the introduction of ready-to-use (RTU) infant feeds in place of powdered infant feeds (PIFs) as a standard formula for infants under the age of 1 year who are unable to be breastfed. Internationally and locally there is grave concern regarding the safety and efficacy of mixing PIFs, especially in a hospital setting,...

Supervisory Control And Data Acquisition (SCADA) systems have been widely used in industry applications. Due to their application specific nature, most SCADA systems are heavily tailored to their specific applications. For example, a remote terminal unit (RTU) that monitors and controls a production well in an oilfield is only connected with a few sensors at the well it resides. The RTU usually...

Remote and centralized control is the basic need of todays industrial control systems, where a separate microcomputer monitors and controls the process at each remote unit. Collecting and displaying data from remote sites on a single monitoring unit let the operator to supervise all the sites, regardless of the volume of industry. Different aspects of Supervisory Control And Data Aquisition (SC...
