Laser (dinghy)

The International Laser Class sailboat, also called Laser Standard and the Laser One is a popular one-design class of small sailing dinghy. According to the Laser Class Rules the boat may be sailed by either one or two people, though it is rarely sailed by two. The design, by Bruce Kirby, emphasizes simplicity and performance. The dinghy is manufactured by independent companies in different parts of the world, including LaserPerformance Europe (Americas and Europe), Performance Sailcraft Australia (Oceania) and Performance Sailcraft Japan.

The Laser is one of the most popular single-handed dinghies in the world. As of 2012, there are more than 200,000 boats worldwide. A commonly cited reason for its popularity is that it is robust and simple to rig and sail in addition to its durability. The Laser also provides very competitive racing due to the very tight class association controls which eliminate differences in hull, sails and equipment.

The term "Laser" is often used to refer to the Laser Standard (the largest of the sail plan rigs available for the Laser hull). However there are two other sail plan rigs available for the Laser Standard hull and a series of other "Laser"-branded boats which are of completely different hull designs. Examples include the Laser 2 and Laser Pico. The Laser Standard, Laser Radial and Laser 4.7 are three types of 'Laser' administered by the International Laser Class Association.

Teststrecke

Teststrecke, meaning Test Track in German, is a portable steel roller coaster owned by the German showman partnership Meyer & Rosenzweig. It was imported from Dorney Park & Wildwater Kingdom in 2008, and now generally tours in Germany, with occasional visits to the Netherlands. It was designed by the now-renowned ride engineer, Anton Schwarzkopf.

The trains on Teststrecke are themed to resemble racing cars and designed by Zierer. Each train has a single lap bars to secure riders in their seats. It can operate all three at peak times, but it runs with one when there are no queues.

The ride

The ride starts with a slow 93-foot chain lift hill, leading to a right hand near vertical curved first drop, and two consecutive vertical loops. The ride then turns into left-hand helix, up and through the center of second loop. Another left turn helix, goes down and goes straight upward diagonally between the vertical loops, followed by a 360-degree helix, starting from right, leading into a brake run that leads into two right turns and back into the station.

Film (film)

Film is a 1965 film written by Samuel Beckett, his only screenplay. It was commissioned by Barney Rosset of Grove Press. Writing began on 5 April 1963 with a first draft completed within four days. A second draft was produced by 22 May and a forty-leaf shooting script followed thereafter. It was filmed in New York in July 1964.

Beckett’s original choice for the lead – referred to only as “O” – was Charlie Chaplin, but his script never reached him. Both Beckett and the director Alan Schneider were interested in Zero Mostel and Jack MacGowran. However, the former was unavailable and the latter, who accepted at first, became unavailable due to his role in a "Hollywood epic." Beckett then suggested Buster Keaton. Schneider promptly flew to Los Angeles and persuaded Keaton to accept the role along with "a handsome fee for less than three weeks' work."James Karen, who was to have a small part in the film, also encouraged Schneider to contact Keaton.

The filmed version differs from Beckett's original script but with his approval since he was on set all the time, this being his only visit to the United States. The script printed in Collected Shorter Plays of Samuel Beckett (Faber and Faber, 1984) states:

Lubrication theory

In fluid dynamics, lubrication theory describes the flow of fluids (liquids or gases) in a geometry in which one dimension is significantly smaller than the others. An example is the flow above air hockey tables, where the thickness of the air layer beneath the puck is much smaller than the dimensions of the puck itself.

Internal flows are those where the fluid is fully bounded. Internal flow lubrication theory has many industrial applications because of its role in the design of fluid bearings. Here a key goal of lubrication theory is to determine the pressure distribution in the fluid volume, and hence the forces on the bearing components. The working fluid in this case is often termed a lubricant.

Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. In that case the position of the free surface is itself unknown, and one goal of lubrication theory is then to determine this. Surface tension may then be significant, or even dominant. Issues of wetting and dewetting then arise. For very thin films (thickness less than one micrometre), additional intermolecular forces, such as Van der Waals forces or disjoining forces, may become significant.
