Flip chip, also known as controlled collapse chip connection or its abbreviation, C4, is a method for interconnecting dies such as semiconductor devices, IC chips, integrated passive devices and microelectromechanical systems (MEMS), to external circuitry with solder bumps that have been deposited onto the chip pads. The technique was developed by General Electric's Light Military Electronics Department, Utica, New York. The solder bumps are deposited on the chip pads on the top side of the wafer during the final wafer processing step. In order to mount the chip to external circuitry, it is flipped over so that its top side faces down, and aligned so that its pads align with matching pads on the external circuit, and then the solder is reflowed to complete the interconnect. This is in contrast to wire bonding, in which the chip is mounted upright and fine wires are welded onto the chip pads and lead frame contacts to interconnect the chip pads to external circuitry.
Speed bumps are a class of traffic calming devices that use vertical deflection to slow motor-vehicle traffic in order to improve safety conditions. Variations include the speed hump, speed cushion, and speed table.
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked. "Independent" refers to the motion or path of movement of the wheels or suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together.
Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure and can even slightly reduce the energy expenditure of the lead vehicle.

King's College Boat Club is the rowing club for members of King's College, Cambridge. The first record of King’s rowing is in 1838.
Cambridge University Women's Boat Club (CUWBC) was the rowing club for women at the University of Cambridge. CUWBC fielded both a lightweight eight that races against Oxford at the Henley Boat Races, and two openweight eights that race at the Women's Boat Race. In April 2020 it was agreed that the club would be combined with the men's club CUBC and the lightweight men's club CULRC.

Hump, The Hump, or humping may refer to:
Tape-automated bonding (TAB) is a process that places bare semiconductor chips (dies) like integrated circuits onto a flexible circuit board (FPC) by attaching them to fine conductors in a polyamide or polyimide film carrier. This FPC with the die(s) can be mounted on the system or module board or assembled inside a package. Typically the FPC includes from one to three conductive layers and all inputs and outputs of the semiconductor die are connected simultaneously during the TAB bonding. Tape automated bonding is one of the methods needed for achieving chip-on-flex (COF) assembly and it is one of the first roll-to-roll processing type methods in the electronics manufacturing.
The 60th 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 30, 1976. Polesitter Johnny Rutherford took the lead on lap 80, and was leading when rain halted the race on lap 103. Two hours later, the race was about to be resumed, but rain fell again. USAC officials called the race at that point, reverted the scoring back to the completion of lap 102, and Johnny Rutherford was declared the winner. Rutherford famously walked to Victory Lane, his second career Indy 500 triumph, having completed only 255 miles (410 km), the shortest official race on record. Janet Guthrie became the first female driver to enter the Indianapolis 500. However, her team was underfunded, and she experienced numerous mechanical and engine problems during the month. While she managed to pass her rookie test, and ran numerous practice laps in multiple cars, she was unable to make an attempt to qualify. She would return with a successful effort a year later in 1977.
The 89th Indianapolis 500 was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 29, 2005. It was the premier event of the 2005 IndyCar Series season and the tenth Indy 500 sanctioned by the Indy Racing League. Dan Wheldon won the race, his first of two Indy victories. Wheldon became the first British-born winner since Graham Hill in 1966. It was the second consecutive Indy victory for Honda, and the first victory for the Dallara chassis since 2002. It was also the long-awaited first Indianapolis 500 victory for car owner Michael Andretti of Andretti-Green Racing. After many years of failing to win the race as a driver, Andretti finally achieved victory at Indianapolis as an owner.
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations.
Mogul skiing is a freestyle skiing competition consisting of one timed run of free skiing on a steep, heavily moguled course, stressing technical turns, aerial maneuvers and speed. Internationally, the sport is contested at the FIS Freestyle World Ski Championships, and at the Winter Olympic Games.
The 93rd Indianapolis 500 was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday May 24, 2009. It was the 14th Indy 500 sanctioned by the Indy Racing League, and the premier event of the 2009 IndyCar Series season.
Shepherding is a tactic and skill in Australian rules football, a team sport. The term originates from the word shepherd, someone who influences the movement of sheep in a paddock. Using their body as an obstruction, Australian rules footballers can influence the movement of opponents, most often to prevent them from gaining possession or reaching the contest. This can be achieved legally while the ball is in play by a number of methods which include blocking, pushing or bumping. As shepherds are not counted in official statistics, it is classified as a "one percenter" skill but is an important aspect of team play to clear an attacking path for their team. According to the Laws of Australian Football, a player can shepherd an opposition player when the ball is within five metres, with the exception of contests where players contest the ball in the air, i.e. marking contests and ruck contests, or when the ball is not in play.
The 94th Indianapolis 500 was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 30, 2010. It was the 15th Indy 500 sanctioned by the Indy Racing League, and was the premier event of the 2010 IZOD IndyCar Series season. The race was won by Dario Franchitti, ahead of Dan Wheldon and Marco Andretti. Tony Kanaan, who had started in the final position, ran as high as second during the race before finishing eleventh.
The whirly tube, corrugaphone, or bloogle resonator, also sold as Free-Ka in the 1960s-1970s, is an experimental musical instrument which consists of a corrugated (ribbed) plastic tube or hose, open at both ends and possibly wider at one end (bell), the thinner of which is rotated in a circle to play. It may be a few feet long and about a few inches wide. The faster the toy is swung, the higher the pitch of the note it produces, and it produces discrete notes roughly belonging to the harmonic series, like a valveless brass instrument generates different modes of vibration. However, the first and the second modes, corresponding to the fundamental and the second harmonics, are reported as being difficult to excite. To be played in concert the length of the tube must be trimmed to tune it.
