Course Highlights This course features a Java applet in the tools section that simulates photovoltaic panel collection as well as handouts from the class in the lecture notes section and solar data in the study materials. Course Description This class will study the behavior of photovoltaic solar energy systems focusing on the behavior of "stand-alone" systems. The design of stand-alone photovoltaic systems will be covered. This will include estimation of costs and benefits taking into account any available government subsidies. Introduction to the hardware elements and their behavior will be included.

Resolved by the Senate (the House of Representatives concurring), That (a) a revised edition of the brochure entitled ``How Our Laws Are Made'', under the direction of the Parliamentarian of the House of Representatives in consultation with the Parliamentarian of the Senate, shall be printed as a Senate document, with suitable paper cover in the style selected by the chairman of the Joint Committee on Printing. (b) There shall be printed-- (1)(A) 250,000 copies of the brochure for the use of the House of Representatives, distributed in equal numbers to each Member; (B) 100,000 copies of the brochure for the use of the Senate, distributed in equal numbers to each Member; (C) 2,000 copies of the brochure for the use of the Joint Committee on Printing; and (D) 1,400 copies of the brochure for distribution to the depository libraries; or (2) if the total printing and production costs of copies in paragraph (1) exceed $180,000, such number of copies of the brochure as does not exceed total printing and production costs of $180,000, with distribution to be allocated in the same proportion as in paragraph (1).

This map shows all telephone area codes in use as of 2008-06-12 in the United States and Canada. Area codes that have not yet taken effect are shown with a green line and the area code in parentheses. Some planned area codes that have been cancelled or indefinitely postponed are no longer shown. Check the separate page for information about the 19-way split in the Caribbean area. There is also a Caribbean map. Some of the area codes shown above are not yet in use. For information on the split dates of new area codes, see the table on the separate page. Detailed maps of some of the metropolitan areas may be added in the future, along with time-zone boundaries. All boundaries shown are approximate.

You give humanity a creative tool, the first thing a human will do is - well - make a tool with it. Since the Spore demo’s release, it’s become a bukkake wave sweeping the web: comedy pornographic images via Spore. Spornography - aka “Sporn”. Has it reached a climax yet? We don’t know, but we think it’s as good a time as any to stop and survey the lie of the land. And, yes, it’s sticky. Beneath the cut you’ll find gathered a large selection of the phalluses, the pseudo-sex-acts and general disturbing animated parts of the gamers’ subconcious. For God’s sake, don’t click it at work. Right - we’re dividing these into loose categories. There’s certainly some we’ve missed - there’s a brilliant missionary position one I can’t find again - but it’ll do for now. If you’ve got a favourite, please, post it in the comments thread and we’ll work it in later.

0806.2442 Observation of a push force on the end face of a nm fiber taper exerted by outgoing light |

Abstract: There are two different proposals for the momentum of light in a transparent dielectric of refractive index n: Minkowski s version nE/c and Abrahm s version E/ nc , where E and c are the energy and vacuum speed of light, respectively. Despite many tests and debates over nearly a century, momentum of light in a transparent dielectric remains controversial. In this Letter, we report a direct observation of the inward push force on the end face of a free nm fiber taper exerted by the outgoing light. Our results clearly support Abraham momentum. Our experiment also indicates an inward surface pressure on a dielectric exerted by the incident light, different from the commonly recognized pressure due to the specular reflection. Such an inward surface pressure by the incident light may be useful for precise design of the laser-induced inertially-confined fusion.
