New features of mechanical ventilators are frequently introduced, including new modes, monitoring techniques, and triggering techniques. But new rarely translates into any measureable improvement in outcome. We describe 4 new techniques and attempt to define what is a new invention versus what is innovative-a technique that significantly improves a measurable variable. We describe and review th...

In this work the design and characterization of an optoelectronic automated measurement system it is presented. The optoelectronic devices of this system are an optical transmitter, the optical components and the optical receiver, which were selected for a great precision of the system. The mechanical system allows free displacement of the components as well as the devices that generate the mov...

Apnea of prematurity (AOP) is one of the most common diagnoses in preterm infants. Severe and recurrent apneas are associated with cerebral injury and adverse neurodevelopmental outcome. Despite pharmacotherapy and respiratory support to prevent apneas, a proportion of infants continue to have apneas and often need tactile stimulation, mask, and bag ventilation and/or extra oxygen. The duration...

Single crystals and polycrystalline diamond films of several thicknesses were deposited using oxygen/acetylene combustion flame technique. The substrate used was pure polycrystalline molybdenum subjected to mechanical polishing. Quality and microstructural characteristic of diamond produced were investigated using X-Ray diffraction, Raman Spectroscopy, Scanning and Transmission Electron Microsc...

Hybrid stepper motors (HSMs) are commonly used in many cost-sensitive industrial and consumer applications. With the use of micro-stepping techniques, they could theoretically achieve a very high resolution in positioning of mechanical loads, even without position sensors. However, it is well known that HSMs are affected by a large torque ripple, due to cogging and phase unbalancing. This, in t...

Automated methodology for monitoring the presence of one or more glycosidases in biological extracts has been described (l-7). These procedures require use of large amounts of synthetic glycoside(s) (l-4,6,7), compound automated systems (5), or extensive mechanical and/or electrical alterations of existing apparatus (8). The present paper describes a simple modification of the Technicon Basic A...

purpose : to compare the outcome of surgery and postoperative complications between using manually dissected cornea in descemet’s stripping with endothelial keratoplasty (dsek) and using eye bank automated precut cornea in descemet’s stripping with automated endothelial keratoplasty (dsaek) methods : forty eyes with indication of endothelial keratoplasty (ek) were included in this randomized pr...

This study analyses the concept of cost functions for semi-automated Straddle Carrier (SC), Rubber Tyred Gantry (RTG) and automated Rail Mounted Gantry (RMG) container yard operating cranes. It develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

Many experiments in C. elegans neurobiology and development benefit from automated imaging of worm behavior. Here we describe procedures for building a flexible and inexpensive imaging system using standard optical and mechanical components.

The face Detection methodsis used in order to provide security. The mentioned methods problems are that it cannot be categorized because of the great differences and varieties in the face of individuals. In this paper, face Detection methods has been presented for overcoming upon these problems based on skin color datum. The researcher gathered a face database of 30 individuals consisting of ov...
