A Study of Thermal Comfort and Cost Effectiveness of Stratum Ventilation
… thermal comfort at a relatively elevated indoor temperature in which less energy use is consumed. It seems that only limited studies on the evaluation of neutral temperature, which is a condition of neither slightly warm nor slightly cool, are supported by actual human comfort surveys. Moreover, …

Spectral modelling of molecular nitrogen in Aurora
… of N+2 1N (0,1), (1,2), (2,3) bands and a neutral N2 2P (0,3) band. Ab initio models were created for describing the populations of vibrational and rotational energy levels in both excited and ionised N2 molecules in the ionosphere. In the rotational profiles the species are treated to be …

Development of ice-bonded ballast in sub-freezing temperatures and its effect on maintenance operations during a winter rail break
Sub-freezing temperatures result in ice formation within the ballast layer of railroad track. Given the proper moisture and fouling conditions, the retained moisture bonds ballast particles together changing the mechanical properties. For above-freezing temperatures, longitudinal track resistance …

Solar activity variations of the ionospheres of Venus and Mars
… models to show that the overall expansion of the neutral atmosphere due to increasing neutral temperature is the dominant factor in determining how electron densities in the dayside ionosphere above the ionospheric peak react to changing solar irradiance. Using in situ observations from Pioneer …

An Investigation into the Effect of Gender and Clothing on Thermal Comfort and Energy Savings in Classrooms: A Case Study of University Buildings in the State of Kuwait
… clothing, gender, air velocity, humidity, air temperature, operative temperature, predicted mean vote (PMV) and thermal sensation vote (TSV) were examined in prior empirical investigations of thermal comfort in tropical settings. What is not fully understood, for example, is the impact of …

Dispersion Curve Estimation for Longitudinal Rail Stress Measurement
There currently exists no reliable, non-destructive method for measuring stress in railroads and other similar structures without the need for a calibration measurement. Major limitations which have hindered previous techniques include sensitivity to boundary conditions, insensitivity to stress, …

Thermal comfort assessment of primary school children in a warm and humid climate : a case study of Imo State, Nigeria
… the concern over climate change. The increasing temperature caused by climate change is likely impacting the comfort and the health of building occupants, especially in a primary school setting where young children engage in-class lessons for an extended period. This thesis presents the results …
