Ultraviolet (UV) sunlight actinometers were developed based on the photolysis of nitrate and nitrite. Photon exposures (i.e. time-integrated irradiances) were quantified from the photochemical production of salicylic acid (SA) or p-hydroxybenzoic acid (pHBA) formed by the reaction of the hydroxyl radical with benzoic acid. The solar response bandwidth for the nitrate actinometer in quartz tubin...

Prompted by feedback from several partners in the industry, Sun is proposing a change to the specification of floating-point in the Java programming language. The current Java programming language and virtual machine specifications require that all single and double precision floating-point calculations must round their results to the IEEE 754 single and double precision formats, respectively. ...

The entire process of creating and executing applications that solve interesting problems with acceptable cost and accuracy involves a complex interaction among hardware, system software, programming environments, mathematical software libraries, and applications software, all mediated by standards for arithmetic, operating systems, and programming environments. This panel will discuss various ...

Advances in field programmable gate arrays (FPGAs), which are the platform of choice for reconfigurable computing, have made it possible to use FPGAs in increasingly many areas of computing, including complex scientific applications. These applications demand high performance and high-precision, floating-point arithmetic. Until now, most of the research has not focussed on compliance with IEEE ...
