Bodkin Design & Engineering (BD&E) has been awarded a contract from the US Army to develop a High-Energy Laser (HEL) test capability for non-contact mapping of target surface temperature during HEL engagements. The sensor, based on BD&E´s patented HPA hyperspectral imaging technology, simultaneously maps the radiometrically-correct target radiance and the target surface temperature. The High-Energy Laser program is a key element in the US arsenal of defensive weaponry to...

On the hottest day of the New York City summer in 2011, a white roof covering was measured at 42 degrees Fahrenheit cooler than the traditional black roof it was being compared to, according to a study including NASA scientists that details the first scientific results from the city's unprecedented effort to brighten rooftops and reduce its "urban heat island" effect. The dark, sunlight-absorbing surfaces of some New York City roofs reached 170 degrees Fahrenheit on July 22, 2011, a day...

The benefits of far infrared saunas are becoming known across the country. However, complaints LuxSauna personnel continuously hear from users of other saunas include how the far infrared sauna they purchased just isnât making them sweat, or theyâre not heating up fast enough. Denver, Colorado (PRWEB) October 14, 2011 LuxSauna reviews explain the benefit of thinking twice when reading marketing hype. There is a significant amount of marketing hype and Mocked up...

Boston College researchers' designer material has potential applications for thermophotovoltaics A designer metamaterial has shown it can engineer emitted "blackbody" radiation with an efficiency beyond the natural limits imposed by the material's temperature, a team of researchers led by Boston College physicist Willie Padilla report in the current edition of Physical Review Letters. A "blackbody" object represents a theorized ideal of performance for a material that perfectly absorbs all...

Scientists are able to learn about the atmospheres and surfaces of planets by studying their spectra - the different wavelengths of light which they reflect or absorb. However, when researchers study spectra of Venus, the hottest planet in the Solar System, they run into a problem. Its high temperatures and pressures seriously affect the data. Venus and Earth are often described as sister worlds. However, the second planet from the Sun has obviously evolved in a very different manner from our...

Infrared Thermography is a technique that can be employed in the plastic industry for process optimization and quality improvement, as well as in the development of new tools. In the thermoplastic injection process, a large amount of information about the transformation process can be collected by taking thermographic images of the recently injected pieces that are still in the mould or that have just been extracted.Infrared RadiationInfrared rays were discovered in 1800 by Frederick William...

Word of the Day
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
