Problem statement: With the advent of the advanced technology and the need for more advanced equipment, the current progress and development of electronic instruments stimulate more interest and efforts for more innovative ideas and better designs. Many real world physical values, such as sounds, temperature, pressure and humidity, can be measured as analog or continuous signals. However, to pr...

purpose this preliminary study aimed to determine the intrarater reliability of the quantitative tests for the study of non-specific low back pain. methods test-retest reliability of the measurements of ratio data was determined by an intraclass correlation coefficient (icc), standard error of measurements (sems), coefficient of variation (cv), and one-way repeated measures anova using the valu...

background: the purpose of the present study was to examine the reliability of scapular kinematic measurements using motion analysis system in subjects with and without general hypermobility syndrome. methods: a methodological study was designed to assess the reliability of scapular movement measurement in two groups of females with and without general hypermobility syndrome. upward rotation, s...

conclusions this study indicated that the delivery rate accuracy of elastomeric infusion pumps is preserved after repeated usage. these laboratory findings suggested that elastomeric pumps could be safely refilled in the successive days to provide postoperative analgesia. results the mean flow rate in the three series of measurements showed a gradual increase; however, the difference was not st...

abstract background: inflammatory bowel disease (ibd) is a group of inflammatory conditions of the colon and small intestine that may have critical consequences on patient’s quality of life (qol). many disease-specific qol tools have been developed recently. the mcmaster inflammatory bowel disease questionnaire (ibdq) is one of them. the aim of this study was to translate into persian and evalu...

An analog phase discriminator, based on the two complementary CMOS switches, was proposed to measure the initial phase of the sinusoidal wave. The circuit structure of the phase discriminator and its principle were presented, and the phase computational formula was derived through a series of circuit theories. So the initial phase was acquired directly from the circuit, which covered a wide fre...

Application of built-in self-test circuitries allows to improve the testing quality and reliability of complex analog and mixed-signal IC. BIST-circuitry is integrated to original circuit for the purpose of test signal generation, measurement of output responses and decision-making about correctness of circuit under test functioning. The most part of BIST-circuitries for analog and mixed-signal...

This paper describes a research project on wireless electrocardiogram (ECG) monitoring systems. A detection and measurement processor designed by a MSP430 microcontroller accomplishes the analog-to-digital conversion, digital filtering, QRS wave detection, and heart rate calculation. The data of detection can be sent to the central controller and personal computer (PC) by wireless on-chip MG245...
