The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...

Received Jan 6, 2018 Revised Mar 8, 2018 Accepted Mar 23, 2018 One of the effective ways to diagnose various respiratory diseases is using spirometry test. Good spirometer comes with excellent graphical user interface. Spirometer is used to measure lung parameters such as Forced Expiratory Volume in the first second and the sixth seconds (FEV1 and FEV6). This paper presents an algorithm with Gr...

BACKGROUND The performance of spirometers is often evaluated under ideal conditions with computer-generated waveforms or in vivo testing with healthy subjects. Real-life conditions are less ideal because of comorbidities, age of the subjects, and a variety of air flow limitations. Evaluation of new spirometry equipment can also be performed under these less favorable conditions. The Spirospec i...

error attributable to the apparatus in the test as commonly performed, and as a result of this work designed a spirometer which was substantially free from recording error (Bernstein, D'Silva, and Mendel, 1952). No systematic investigation has been attempted in the past of the various factors which contribute to the amount of air respired by a subject submitted to the test. With a spirometer wh...

In this work the classification of Force Expiratory volume in 1 second (FEV 1) in pulmonary function test is carried out using Spirometer and Self Organizing Feature Map Algorithm. Spirometry data are measure with flow volume spirometer from subject (N=100 including Noramal, and Abnormal) using standard data acquisition protocol. The acquire data are then used to classify FEV1. Self Organizing ...

For a doctor to determine the most accurate diagnosis of diseases of the respiratory tract, it must be as accurate as possible insight into the problem. Imaging technology allows to look into the body, unfortunately for example lung is an organ, where without contrast agent does not buy the picture. Furthermore, the methods that can be used are whole body plethysmography or, a better option, sp...

Patient-based studies of agreement between spirometers arguably have a place in evaluating and accepting new equipment into clinical use. These studies typically trail in credibility behind more controllable simulations such as computer-driven benchmark wave forms,1 other bench techniques, and comparisons with normal subjects. These latter methods would be expected to give more consistent input...

in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...
