Relative strength index The relative strength index is a technical indicator used in the analysis of financial markets. It is intended to chart the current and historical strength or weakness of a stock or market based on the closing prices of a recent trading period. The indicator should not be confused with relative strength. The RSI is classified as a momentum oscillator, measuring the velocity and magnitude of directional price movements. Momentum is the rate of the rise or fall in price. The RSI computes momentum

Investigating the microstructure of keratin extracted from wool: Peptide sequence (MALDI-TOF/TOF) and protein conformation (FTIR) â Investigations of keratins extracted from wool by reduction hydrolysis and by alkaline hydrolysis showed that their chemical compositions and secondary structures were similar to original wool. The keratin isolates were similar in amino acid, Amides I and II, and secondary structure to each other and to original wool.

Fourier-transform infrared spectroscopy The term Fourier transform infrared spectroscopy originates from the fact that a Fourier transform (a mathematical process) is required to convert the raw data into the actual spectrum.n a Michelson interferometer adapted for FTIR, light from the polychromatic infrared source, approximately a black-body radiator, is collimated and directed to a beam splitter. Ideally 50% of the light is refracted towards the fixed mirror and 50% is transmitted towards the moving mirror.

Average True Range Indeed, the Average True Range (ATR) is a brilliant volatility indicator. It identifies the strength of the price movement or volatility. A highly volatile market is typically followed by a quiet market and because the ATR identifies when the volatility increases, it can help confirm the breakout of a new trend.

Fourier-transform infrared spectroscopy The goal of any absorption spectroscopy (FTIR, ultraviolet-visible (UV-Vis) spectroscopy, etc.) is to measure how well a sample absorbs light at each wavelength.TIR is a method of measuring an infrared absorption spectrum. For a discussion of why people measure infrared absorption spectra, i.e. why and how substances absorb infrared light, see the article: Infrared spectroscopy.

Solar irradiance Total solar irradiance (TSI), is a measure of the solar radiative power per unit area normal to the rays, incident on the Earth's upper atmosphere. The solar constant is a conventional measure of mean TSI at a distance of one Astronomical Unit (AU).

How should I interpret 'test information function (TIF)' results in IRT? Normally, test reliability in CTT is about alpha coefficient. But, in IRT it is about 'test information function (TIF)'. Let say by applying CTT in a test analysis, we have an alpha coefficient reliability result of 0.75. Then, we can easily refer this result to a kind of 'interpretation ranges' to make a judgement for the test reliability; e.g. poor, acceptable, high etc.

Solar irradiance Total solar irradiance (TSI), is a measure of the solar radiative power per unit area normal to the rays, incident on the Earth's upper atmosphere. The solar constant is a conventional measure of mean TSI at a distance of one Astronomical Unit (AU). Irradiance is a function of distance from the Sun, the solar cycle, and cross-cycle changes. Irradiance on Earth is most intense at points directly facing (normal to) the Sun.

- It is measured perpendicular to the incoming sunlight. Total solar irradiance (TSI), is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere. The solar constant is a conventional measure of mean TSI at a distance of one astronomical Unit (AU).

- Average true range. Average true range (ATR) is a technical analysis volatility indicator originally developed by J. Welles Wilder, Jr. for commodities. The indicator does not provide an indication of price trend, simply the degree of price volatility. The average true range is an N-day smoothed moving average (SMMA) of the true range values.

The tibial tuberosityâtrochlear groove distance; a comparative study between CT and MRI scanning Received 9 May 2005, Accepted 6 June 2005, Available online 14 July 2005. CT scan is the gold standard for the measurement of the tibial tuberosity–trochlear groove distance (TTTG). The aim of this study was to evaluate the reliability of the TTTG on MRI compared to CT scan. Twelve knees in 11 patients underwent CT and MRI examination for patellofemoral instability or anterior knee pain.

Fourier-transform infrared spectroscopy FTIR redirects here. FTIR may also refer to Frustrated total internal reflection. Fourier transform infrared spectroscopy (FTIR) is a technique which is used to obtain an infrared spectrum of absorption, emission, photoconductivity or Raman scattering of a solid, liquid or gas.n a Michelson interferometer adapted for FTIR, light from the polychromatic infrared source, approximately a black-body radiator, is collimated and directed to a beam splitter. Ideally 50% of the light is refracted towards the fixed mirror and 50% is transmitted towards the moving mirror.

Thyrotropin/Thyroid Stimulating Hormone (TSH) Measurement A serum TSH measurement is required for confirming that an elevated thyroid hormone level is due to hyperthyroidism and not a thyroid hormone binding protein abnormality (such as FDH). A serum TSH measurement is the primary test for detecting amiodarone-induced thyroid dysfunction (see Guideline 5). As shown in Table 1, binding protein abnormalities or assay technical problems are the most common causes for a discordant FT4/TSH relationship.
