Reconstruction of the Temperature Profile Along a Blackbody Optical Fiber Thermometer
… at the end of the fiber at two wavelengths. The temperature at the sensing tip of the fiber can then be inferred using Planck's law and the ratio of the spectral intensities. If, however, the length of the optical fiber is exposed to elevated temperatures, erroneous temperature measurements will …

Analytical solutions for temperature profile prediction in multi-layered pavement systems
Accurate prediction of pavement temperature profile is essential to better characterize the mechanistic properties of paving materials and predict pavement responses under traffic and environmental loadings. In practice, characterizing the field temperature profiles are desired in order to …

Moisture Content Determination and Temperature Profile Modeling of Flexible Pavement Structures
… it behaves more as a viscous fluid at high temperatures and as an elastic solid at low temperatures. Between these two temperature extremes, a combination of these properties is evident. Thus, understanding the environmental effects on flexible pavements allows better prediction of pavement …

Atmospheric temperature profile retrievals using 54 and 118-GHz spectral observations from the Proteus Aircraft
Temperature profile retrievals based on passive microwave spectral observations from an aircraft were made with a Linear Least Squares Estimator (LLSE). The National Polar-orbiting Observational Environmental Satellite System (NPOESS) Aircraft Satellite Testbed-Microwave (NAST-M) is an imaging …

The Implementation of Stellar Occultation Light Curve Modelling for Arbitrary Planetary Atmospheric Structures and the Analysis of Pluto’s Occultation Light Curves and Its Atmosphere
… planetary atmosphere is directly related to the temperature profile of the planetary atmosphere. In this thesis, we implemented the occultation model derived by Chamberlain and Elliot (1997) [2], which is compatible with any occulting body with arbitrary temperature profile. The implementation …

Design of a pultrusion die using a design optimization technique
… is to design a pultrusion die with a desired temperature profile. Design optimization programs were developed to synthesize the number of cartridge heaters, power input and location of each cartridge heater for a laboratory-scale pultrusion die. This is the first step in developing a …

Investigation of edge effects in thermoacoustic couple measurements
… though perhaps causing local deviations in the temperature profile, do not affect the temperature profile in interior regions of the plate. To investigate whether edge effects are the cause of any of these discrepancies, we have constructed a TAC with two thermopile, whose conjunction do not lie …

Influência da dissipação viscosa na transferência de calor em tubos concêntricos no escoamento turbulento
The temperature profile for a turbulent flow, of a newtonian fluid flowing between two concentric tubes has been determined. The velocity profile was based on the Deissler and Quarmby equations for turbulent flows. The momentum difusivity equation for the turbulent flow has been evaluated according …

An Improved Biosolid Gasifier Model
… equivalence ratios and biosolid feed rates. The temperature profile inside of the gasifier was recorded over the span of four months, and an average profile was used in the base case scenario. The improved model gave reasonable predictions of the axial bed temperature profile, syngas composition, …

Retrieval of cloud-cleared atmospheric temperature profiles from hyperspectral infrared and microwave observations
… thesis addresses the problem of retrieving the temperature profile of the Earth's atmosphere from overhead infrared and microwave observations of spectral radiance in cloudy conditions. The contributions of the thesis are twofold: improvements in 1) microwave instrumentation and 2) hyperspectral …
