Reconstruction of the Temperature Profile Along a Blackbody Optical Fiber Thermometer
<p>A blackbody optical fiber thermometer consists of an optical fiber whose sensing tip is given a metallic coating. The sensing tip of the fiber forms an isothermal cavity, and the emission from this cavity is approximately equal to the emission from a blackbody. Standard two-color optical fiber …

A liquid-in-glass thermometer with sub-microKelvin resolution, and its application for calorimetry
… first constructed as a miniature liquid-in-glass thermometer in which the meniscus level was read by a Michelson interferometer. Contact angle hysteresis was limited by a wetting film and the low meniscus velocity. The sub-microKelvin resolution achieved was the lowest known for any thermometer …

Environmental errors in use of the airborne infrared radiation thermometer to measure sea-surface temperature
An airborne infrared radiation thermometer (IRT) used to measure the sea-surface temperature is described, and the basic radiation principles on which the operation of the instrument depends are discussed. The environmental factors which may tend to introduce errors into the measurement of …

Development of a Miniature, Semi-Distributed Sapphire Fiber Optic Thermometer for Harsh and High Temperature Environments
… error potential from cross sensitivity of the thermometer with applied strain. This work has been variously funded by Pratt & Whitney and the Department of Energy.

Analysis of R-2R digital-to-analog converter with equal current switching
… switching glitches at the output, while a fully thermometer-coded DAC benefits from the relaxed DNL but requires a large area to realize. The R-2R DAC with equal current switching into the ladder network can be implemented using very low currents with more relaxed current matching requirements …

Finding the swing voter : definitions and survey methods for voter classification
… which can be captured using the ANES Feeling Thermometer scales. A metric of the difference between the scores given to the Republican and Democratic candidates is used, based in the work of William Mayer. This metric suffers from significant survey error, but is related to party ID and …

Thermometry and cooling of ultracold atoms in an optical lattice
… of the size of the boundary region to act as a thermometer for the system, representing the first demonstration of spin gradient thermometry. This thermometer represents the first practical method for thermometry in the Mott insulator, and has features of high dynamic range and tunable …

Infrared thermography (IRT) for the assessment of microvascular skin blood flow in a specialist connective tissue disease unit
… two large randomised pilot studies. An infrared thermometer technique was developed, validated against IRT, and subsequently used for the assessment of peripheral vasospasm in a twin study into the heritability of RP. The utility of inspection of thermograms for detecting clinically active LS …

Opportunities and Challenges in Identification and Classification of Heat Stress Risk Based on Analysis of Individual and Neighborhood Level Factors
… workers in Birmingham, Alabama wore a small thermometer attached to their shoe. Their occupational Wet Bulb Globe Temperatures (WBGT), a comprehensive heat exposure index, was estimated from either temperature from the shoe thermometers or nearby weather stations. In the second and third …

Radio-Frequency Capacitive Gate-based Sensing for Silicon CMOS Quantum Electronics
… I have experimentally demonstrated a primary thermometer by embedding a single-gate Si NWFET with the rf capacitive gate-based sensor. The thermometer, termed as gate-based electron thermometer (GET), relies on cyclic electron tunneling between discrete energy levels of a quantum dot and a …

Experimental Realisation of Energy Harvesters built from Quantum Dots and Quantum Wells
… performance of a non- invasive single-electron thermometer, and extracts the electrical temperatures via three methods as below. First, we introduced the extracting of the electrical temperatures through fitting the differential-conductance peaks with theoretical models. The advantage of this …

In-Situ, in Air, High-Temperature Phase Transformations in Rare-Earth Niobates and Titanium Oxides (Dysprosium and Yttrium) Using a Thermal-Image Furnace
"The use of a co-existent ""in-situ thermometer"" was found to be a viable method to monitor the sample temperature in the image ""hot-spot"". Studies of YNbO4 and DyNbO4 revealed the existence of a new cubic phase at elevated temperatures beyond the commonly known ferroelastic …

Reliability of torque and temperature feedback for an autonomous glass monitoring system
… two parameters, temperature measured by an IR thermometer and torque measured via the current drawn by a dc motor, to monitor glass blown objects during their production. The intended use of the system is for a glassblowing-pipe turning machine designed to keep a blown glass object centered …
