In this research, an improved psychrometer is developed to solve practical issues arising in the relative humidity measurement of challenging drying environments for meat manufacturing in agricultural and agri-food industries. The design in this research focused on the structure of the improved psychrometer, signal conversion, and calculation methods. The experimental results showed the effect ...

Temperature and relative humidity have opposing effects on evaporative water loss, the likely mediator of the temperature-dependence of nephrolithiasis. However, prior studies considered only dry-bulb temperatures when estimating the temperature-dependence of nephrolithiasis. We used distributed lag non-linear models and repeated 10-fold cross-validation to determine the daily temperature metri...

Introduction: The issue of the influence external factors such as meteorological conditions on dynamics coronavirus pandemic is extremely relevant, since understanding physical foundations any process helps predict its results in specific and, to a certain extent, manage it. Objective: In order assess effect relative humidity incidence COVID-19, we analyzed opinions international scientific com...

This paper presents a relative humidity predictions using feedforward artificial neural network (FFNN). Relative humidity values obtained from weather records for Malaysia are used in training the FFNNs. The prediction of the relative humidity is in terms of Sun shine ration and cloud cover. However, three statistical parameters, namely, mean absolute percentage error, MAPE, mean bias error, MB...

The paper deals with the relationship betweeen the water content of washed Serratia marcescens and the thermodynamic activity of water, a,, over the range 0 < a, < 1.0. Two overlapping types of measurement are used: osmotic water exchange and water-vapour sorption. The data are given in terms of the equation w = Bm-' where w is water content, m is external osmolality (actual or effective, depen...
