The purpose of this research was to review the literature on home blood pressure measurement (HBPM) and to provide recommendations regarding HBPM assessment. Observational studies on HBPM, published after 1992, as identified by PubMed, EMBASE, and Cochrane literature searches were reviewed. Studies were selected if they met the following criteria: 1) self-measurements had been performed with va...

We wanted to use a multiple probes and white light interferometer to measure the surface profile of thin film. However, this system, as assessed with a scanning method, suffers from the presence of a moving stage and systematic sensor errors. In this paper, in order to separate measurement error caused by the moving stage and systematic sensor errors, the least squares analysis is applied to ac...

The shaft deflection is one of critical factors that deteriorate the grease lubrication state inside the tapered roller bearings (TRBs). So, in this paper, on the premise of the TRB subjected to the combined loads and the shaft is deflected, the grease lubrication model at the TRB contacts was constructed, in which the interaction loads, linear and angular displacements of the bearing parts wer...

The search for methods to demonstrate and accurately measure contact area and pressure within human joints has been and remains an active one. Presenssor is a measuring system developed by Fuji Photo Film Co., Ltd. and used in medical applications. The color intensity fades with time and exposure to light. These changes have not been well documented despite the increasing use of Fuji film in bi...

An atomic force microscope (AFM) and spectrometer combined system for in-situ thickness measurement of nano-porous alumina (PA) films is introduced. The AFM is applied to obtain the porosity of PA film, and then we calculate the effective refractive index by Maxwell-Garnett effective dielectric constant theory. The optical thickness of PA film is determined by reflective interference spectromet...

Abstract This article presents the latest of a series research activities aimed to determine deviation originated when Prescale pressure measurement film is used measure size and shape wheel-rail contact area. Despite being an attractive solution due simplicity procedure, it well known that interaction altered by presence film. Consequently, characterizing filtering out systematic error fundame...

Background & Aims: Increase in abdominal pressure can lead to the so-called intra–abdominal compartment syndrome (ACS) that is often observed during the first 24 hours after sever abdominal trauma and surgery. Measurement of the intra abdominal pressure through the bladder as a non-invasive measurement can provide a quick and accurate assessment of abdominal pressure changes. This study was per...

The quadrupole mass spectrometer is now well established as the instrument used almost universally for partial pressure measurement. This spectrometer can be considered as a hot-cathode extractor ionisation gauge with the addition of an electrostatic mass filter between the ion source and the ion collector. This filter consists of a square array of circular rods approximately 6 mm diameter and ...
