For example, a surface that directly faces the sun has a solar angle of incidence of zero, but if the surface is parallel to the sun (for example, sunrise striking a horizontal rooftop), the angle of incidence is 90°.
This current increases with increasing voltage and temperature.
Minority Carrier — A current carrier, either an electron or a hole, that is in the minority in a specific layer of a semiconductor material; the diffusion of minority carriers under the action of the cell junction voltage is the current in a photovoltaic device.

 Current Collection
In Britain overhead wires were required to be 20 feet from the road surface (by special agreement with the inspectorate the wire could be lower, for example when going under low bridges).
The Lineff surface contact system was tested by London's West Metropolitan Tramways in 1890 in Chiswick depot, and consisted of a closed conduit containing a power cable, which was electrically connected to a sectionalized third rail when the tram carrying an electromagnet passed over it.
The unit was connected to the trolleybus by means of a hollow shaft containing the power supply cable and which was pivoted at both ends to allow the vehicle a reasonable amount of sideways movement to either side of the tram rails, without becoming disconnected.

 Current Art Pics
One is obvious versions of famous paintings, two is the use of blurring or a soft focus in parts of a picture and the third is the inclusion of current print sources, much less esteemed, usually identified as low or pop culture.
Cragg emerged in the 70s, in the wake of Minimalism and his first works of note collect sundry lengths of timber into strict rectangular stacks, then small items of refuse into varied formats either on wall or floor.
Collected elements or material are variously sorted by colour, size and shape into an overall format, yet the spacing of elements as much prompts construction, or the overall shape, as construction determines elements, especially in works such as Britain Seen from the North (1981).

 Surface Preparation
Anodizing is a specialized electrolytic surface finish for aluminum that imparts hardness and corrosion resistance, increases paint adhesion, provides electrical insulation, imparts decorative characteristics, and aids in the detection of surface flaws on the aluminum.
If the technical assistance provider suspects that the company's surface preparation system is causing a problem, they should suggest that the company clean test parts with clean rags dipped in a solvent, instead of running the parts through their normal cleaning process.
As the dry ice pellets strike the surface, they induce an extreme difference in temperature (thermal shock) between the coating or contaminant and the underlying substrate, weakening the chemical and physical bonds between the surface materials and the substrate.

 Background information on South Florida Data collection, Explanation of Surface-Water Quality Records
For periods when no samples were collected, daily discharges of suspended sediment were estimated on the basis of water discharge, sediment concentrations observed immediately before and after the periods, and suspended-sediment loads for other periods of similar discharge.
Although data collected periodically may represent conditions only at the time of observation, such data are useful in establishing seasonal relations between quality and streamflow and in predicting long-term sediment-discharge characteristics of the stream.
Replicate samples are collected and analyzed to establish the amount of variability in the data contributed by some part of the collection and analytical process.

In simple terms, surface tension, respectively, surface energy, is to be understood as being a physically measurable tensile stress which can be determined by the molecules in the boundary layer of the substrate and the adhesion strength of these molecules.
An increase in the surface tension, or a 'molecular roughening', of the material surfaces is currently achieved with industrial pre-treatment methods using solvents, primer, plasma, UV radiation, flame-treatment, ozone gassing and corona.
As already stated in the introductory part, it is known according to the invention that two by 90° displaced optical substrate transmissions and their beam displacement along the optical x-axis generate scattering and diffraction effects on both sides of the boundary layer area which are material-specifically dependent on the used wavelength.

 Third rail - Enpsychlopedia   (Site not responding. Last check: 2007-10-14)
One method for reducing current losses is to attach strips of aluminum (which is a better conductor than steel of electricity) to the steel third rail.
These inherent limitations of third-rail systems have largely restricted their use to relatively low-speed, lightweight, trains of the type used in mass transit systems, although 750 V DC third rail is used on many hundreds of main line railway route miles across south and south-east England.
This is not usually a problem as most third-rail rolling stock has multiple current collection shoes along the length of the train, but under certain circumstances it is possible for a train to become "gapped" - stalled with none of its shoes in contact with the live rail.

 Monsoon Current --  Encyclopædia Britannica   (Site not responding. Last check: 2007-10-14)
Unlike the Atlantic and Pacific, both of which have strong currents circulating clockwise north of the Equator, the northern Indian Ocean has surface currents that change with the seasonal monsoon.
surface current of the western Indian Ocean, caused during the northern summer months by the blowing of the southwest monsoon along the coast of East Africa, moving coastal waters northeastward along with it for about 950 miles (1,500 km), with surface velocities reaching up to 9 miles (14 km) per hour.
In the monsoon zone, surface circulation reverses every half year and features two opposing gyres (i.e., semi-closed current systems exhibiting spiral motion) that are separated by the Indian subcontinent.

 Tram - Encyclopedia.WorldSearch   (Site not responding. Last check: 2007-10-14)
Modern trams generally use overhead electric cables, from which they draw current through a pantograph, a bow collector (less commonly) or a trolley pole (the first is most common and used on most new tram designs).
The first operational electric street railway was started in Scranton, Pennsylvania, but the first large-scale electric street railway system was built in Richmond, Virginia in January, 1888.
There also have been street compatible third rail current collection systems, known as surface current collection, more recently as ground level power supply.

Although the film is a rather light comedy on the surface, the government of the time in the country didn't take too lightly to the satire and the film was originally banned in its home country.
While Forman has achieved success with more serious themes in films like "Amadeus", "People Vs. Larry Flynt" and others, it would be enjoyable to see the director return to this style of comedy, somewhat similar to that of Jaques Tati ("Mon Oncle", "M. Hulot's Holiday").

 Various Schematics and Diagrams
This may be the case when running equipment from batteries as well as from a wall adapter that outputs a DC voltage or the enhanced adapter described in the section: Converting an AC output wall adapter to DC.
Another disadvantage of this configuration is that if the currents drawn from the outputs aren't equal, net DC flows through the transformer secondary (with a voltage doubler having no output connection to the common point, this isn't possible).
This adds a gain stage to improve regulation compared to the circuit in the section: Higher Current Operation and is shown using an adjustable regulator though a fixed regulator could also be used.
