National Advanced Driving Simulator

The National Advanced Driving Simulator at the University of Iowa was the largest ground vehicle driving simulator in the world until November 2007, when Toyota's driving simulator at Higashifuji Technical Center was built.

History

The National Advanced Driving Simulator was developed from 1996 through 2001 by the National Highway Traffic Safety Administration (NHTSA) to conduct human factors research on driver behavior.

The simulator consists of a dome with a vehicle cab inside. The vehicle is attached to a motorized turntable that allows the dome to rotate and simulate different driving conditions. 64 feet of longitudinal and lateral travel and 330 degrees of rotation are used to give motion cues to the driver inside. Different makes and models of car cabs can be utilized.

The simulation runs using a software package called Real Time Recursive Dynamics (RTRD), as well as NADSdyna submodules for specific vehicle specs.

Sodium dodecyl sulfate

Sodium dodecyl sulfate (SDS or NaDS), sodium laurilsulfate or sodium lauryl sulfate (SLS) is an organic compound with the formula CH₃(CH₂)₁₁SO₄Na. It is an anionic surfactant used in many cleaning and hygiene products. The salt is of an organosulfate consisting of a 12-carbon tail attached to a sulfate group, giving the material the amphiphilic properties required of a detergent. Derived from inexpensive coconut and palm oils, it is a common component of many domestic cleaning products.

Production

SDS is synthesized by treating lauryl alcohol with sulfur trioxide gas, oleum, or chlorosulfuric acid to produce hydrogen lauryl sulfate. The industrially practiced method typically uses sulfur trioxide gas. The resulting product is then neutralized through the addition of sodium hydroxide or sodium carbonate. Lauryl alcohol is in turn usually derived from either coconut or palm kernel oil by hydrolysis, which liberates their fatty acids, followed by hydrogenation.

Due to this synthesis method, commercial samples of SDS are often a mixture of other alkyl sulfates, dodecyl sulfate being the main component.

Hassan (crater)

Hassan is an impact crater on the southern hemisphere of Saturn's moon Enceladus. Hassan was first observed in Cassini images during that mission's March 2005 flyby of Enceladus. It is located at 31.3° South Latitude, 188.5° West Longitude, and is 14.5 kilometers across. Numerous criss-crossing fractures cut across Hassan, breaking up the regolith on the crater floor.

Hassan is named after the main character from the tale "Hassan of Bassorah" from The Book of One Thousand and One Nights.

Dastaan (TV series)

Dastaan (Urdu: داستان‎) (English: A Tale) is a Pakistani drama serial dramatized by Samira Fazal, and based on the novel Bano, by Razia Butt. It is based on the partition of India and the resulting independence of Pakistan, and takes place between 1947 and 1956. The drama depicts the story of Bano, a girl from a close knit Muslim family living in Ludhiana (located in undivided Punjab) in the pre-1947 era. The story follows Bano and Hassan, as they face the trials and tribulations caused by the 1947 independence.

Dastaan is the first project of its kind taken up by the Pakistani media. Director Haissam Hussain stated in an interview that production for the drama began months in advance, and that the filming itself only took a little over two months. The show was broadcast on Hum TV. The show is now airing in Middle East on channel MBC Bollywood. It is the second highest-rated Pakistani television series.

Dastaan was also aired in India on Zindagi under the title Waqt Ne Kiya Kya Haseen Sitam from 23 March 2015 onwards. Previously, it was decided to run the show under the title Lakeerein, but the decision was later changed.
