The Components: "Tesla Coils are air-cored resonant transformers which generate very high voltages at high frequency. They can be used to produce very long sparks, and have been used in research and for special effects in films and at social events."
WebRing: hub: "This ring is for Web Sites that have some content about Nikola Tesla or Tesla Coils. Tesla Coils being high voltage air core transformers which send long arcs of high voltage electricity through the air. Other HV device pages may be included (Van de Graaf machines, etc...) at the discretion of the RingMaster. Biographies about Nikola Tesla are acceptable. Unacceptable are sites that deal with fringe 'science'! COILERS UNITE!"
WebRing: hub: "
This ring is about anything dealing with high voltage, such as Tesla Coils, electrostatic generators, Jacob's Ladders, Marx Generators, Van de Graaf Generators, ignition coil drivers, flyback drivers, and more!"
marxsch: "the schema the Marx generator is composed by 5 record discs wrapped with aluminium foil plates on both faces, with safety margins ~ 2 cm, separated with party cups ( 3 cups per stage). On the last disc (on the top) is fixed a PVC tube which sustains the charging resistor chains (2 x 10 Mohms on each side of a stage). The spark gap, for each stage is made with two thin copper wires aligned in parallel.
The montage is fed with my DICS (dual ignition coil system- see the schema and the pics on my first page at: http://www.geocities.com/vasil_ro). The tension is rectified with a HV diode, composed from five HV diodes, each of them rated at 20 kV, connected in serie.
The discharge electrodes are connected at the top and the base of the generator."

Surface Metrology Guide - Profile Parameters: "Wt is the height from the lowest valley to the highest peak of the waviness profile"
Surface Metrology Guide - Filtering: "A surface profile may be composed of a range of frequency components. The high frequency (or short wave) components correspond to those that are perceived to be rough and hence called 'roughness'. The low frequency (or long wave) components correspond to more gradual changes in the profile and are often associated with the terms 'waviness' or even 'form'. Note that roughness and waviness are relative terms, just as the words 'high', 'low', 'long' and 'short'. "
Surface Metrology Guide - Instruments: "Type I Profiling Contact Skidless Instruments
Type II Profiling Non-contact Instruments
Type III Profiling Nanometer-Level Scanning Microscopy
Type IV Profiling Contact Skidded Instruments
Type V Other Skidded Instruments
Type VI Area Averaging Instruments"
Surface Metrology Guide - Drawing Indication of Surface Texture: "The following criteria may be used in the specification of surface texture:
Control surface texture only when and where necessary.
Experimentation and experiences are best sources of knowledge in specifying surface characteristics.
In experimentation, statistical techniques have proved to be helpful for establishing correlation between surface characteristics and its intended functions.
Specified surface texture can be produced and measured."

The Moderate Independent: "John McCain can be just another partisan hack. After campaigning side by side with Bush and saying again and again he was doing so in particular because Bush had a better plan for the War on Iraq, as soon as the election was done, McCain admitted he thinks the way the war in Iraq is being fought is entirely wrong, and that, as Kerry said, we should have more troops over there and armor on the vehicles. Compare what McCain says just after the election above with what Kerry was saying way back in May in this article.
You think we needed more troops, Senator McCain? Have 'no confidence' in Rumsfeld and the way the Bush administration is fighting the war? Then you should have gotten behind your friend Kerry.
Obviously McCain was putting his 2008 presidential ambitions above the nation and what is best for the troops. And that is truly sad to see from a man who usually will put principle above party."
