Forecasting Air Pollution Concentrations in Iran, Using a Hybrid Model

The present study aims at developing a forecasting model to predict the next year’s air pollution concentrations in the atmosphere of Iran. In this regard, it proposes the use of ARIMA, SVR, and TSVR, as well as hybrid ARIMA-SVR and ARIMA-TSVR models, which combined the autoregressive part of the autoregressive integrated moving average (ARIMA) model with the support vector regression technique...

Dye Concentrations Determination in Ternary Mixture Solution by Using Colorimetric Algorithm

This publication uses a colorimetric method based on the absorbance spectra of dye solutions to improve on Beer’s law when calculating the dye concentrations of a three-component mixture. The performance of the new method is compared with that of Beer’s law evaluated at three wavelengths, and Beer’s law evaluated at 16 wavelengths. Colorimetric method gives the best prediction of d...

Measurement of formaldehyde concentrations in a subatmospheric steam-formaldehyde autoclave.

A method has been developed for measuring formaldehyde concentrations in a subatmospheric steam-formaldehyde autoclave. Data obtained using this method indicate that the concentration of formaldehyde in the chamber atmosphere is not homogeneous and that it decreases rapidly with time. The penetration of formaldehyde vapour into narrow tubes has also been investigated and was shown to be depende...

Low concentrations of formaldehyde in bronchial asthma: a study of exposure under controlled conditions.

The rapid ascent to 4560 m caused minor symptoms of acute mountain sickness such as headache, nausea, and insomnia in all participants. We did not, however, find any influence of this short term exposure to high altitude on the morphology of the red cells. Our results are in contrast to the morphological changes observed by Rowles and Williams at a similar altitude (4600 m) during an expedition...
