Superbike motorcycles

Posted on April 29th, 2007 in Uncategorized by admin

The term Superbike is used to describe sport bikes with displacement of around 1000cc. Superbikes have have lightweight frames and are powered by high performance engines. Their design is more focused on race track performance than rider comfort.

History

Up until the late 1960s, motorcycles came in three basic formats:

  • Working Bikes: Generally below 250cc, low powered for the average working gentleman to get to work
  • General Bikes: Generally below 500cc/650cc, as working bikes but as they had higher power could also be used for fun at weekends
  • Touring Bikes: anything above that size. Built mainly for touring

The first company to crack this mould was arguably Vincent Motorcycles. Designed as a gentleman’s touring bike, their model’s turn of speed was astounding for days when motorways and freeways didn’t exist. However, its handling was basic, and its shortcomings became clear when faced by a motorway - girder forks!

Then in the 1960s, two bikes were developed which could be both daily commuter as well as weekend racer - these were the first Superbikes. The first was the BSA Rocket 3/Triumph Trident, which was closely followed by the Honda CB750K.

It was the 1971 Kawasaki Z1, however, with its 900cc DOHC engine which finally ushered in the era of the modern superbike. The Z1 was so successful in sales that by the end of that decade the Japanese manufacturers were all building competing machines that were copying the Z1 formula and its DOHC inline-4 engine configuration. The resulting “bike war” among the Japanese manufacturers and required investment in modern engine manufacturing contributed to the demise of the flagging British motorcycle industry.


In Racing

Superbike racing is a category of motorcycle racing that employs modified production motorcycles. Superbike championships are divided into classes based on displacement and amount of modifications allowed.

The Superbike class generally refers to 4 stroke motorcycles from 600cc up to 1000cc (800cc up to 1200cc for twin cylinders) in which substantial modifications are allowed. The class for motorcycles of the same displacements where modifications are limited is generally referred to as “Superstock 1000″

Glossary of Canadian football Kick start

Posted on April 28th, 2007 in Uncategorized by admin

This is a glossary of terms used in Canadian football.

cornerback 
A defensive position on scrimmages. Typical formations include two cornerbacks, whose main duty is to cover wide receivers. See also defensive back.
defensive back 
One of the players whose main duty is to cover wide receivers. Typical defensive formations include five defensive backs: two cornerbacks, two defensive halfbacks, and one safety.
defensive end 
See defensive lineman.
defensive halfback 
A defensive position on scrimmages. Typical formations include two defensive halfbacks, one on each side, but deeper than the cornerbacks. Their main duty is to cover wide receivers. See also defensive back.
defensive lineman 
One the players who line up opposite the offensive line on scrimmages. In a “four-three” formation, there are four defensive linemen: two defensive tackles and two defensive ends. In a “three-four” formation, there are three defensive linemen: one nose tackle and two defensive ends.
defensive tackle 
See defensive lineman.
illegal procedure 
A five-yard penalty against the kicking team or the offence. Most often it is a lineman who moves after taking a three- or four-point stance but before the snap. Other illegal procedures include kicking the ball out of bounds on a kick-off and “no end”.
linebacker 
A defensive player positioned behind the defensive line on scrimmages. In a “four-three” formation, there are three linebackers; in a “three-four”, there are four. Linebackers can be used to blitz the quarterback, make tackles on running plays, or be used for pass coverage.
no end 
A penalty on the offence for having fewer than seven players within one yard of the line of scrimmage at the snap. It is most often called on field goal attempts because of the curved formation of linemen used: if the line is curved back too far, the ends are too far back to be considered linemen, and are called for “illegal procedure: no end”.
nose tackle 
See defensive lineman.
no yards 
A penalty against the kicking team: all offside (sense 2) players must be at least five yards from the ball when it is first touched by a member of the receiving team. In amateur rules, no yards is always a 15-yard penalty; in CFL rules, the penalty is reduced to five yards if the ball hits the ground before being touched.
offside 
Not onside. A player not onside incurs a five-yard penalty.
onside
  1. Legally positioned at the kick-off or the snap. On kick-offs, members of the kicking team must be behind the kick-off line; members of the receiving must be at least 10 yards from the kick-off line. On scrimmages, at the snap the offence must be behind the line of scrimmage; the defence must be at least one yard beyond the line of scrimmage.
  2. A player of the kicking team who can legally recover the kick. The kicker himself and any teammates behind the ball at the time of the kick are onside. Thus on kick-offs all players of the kicking team are onside, but on other kicks usually only the kicker is. The holder on a place kick is not considered onside.
onside kick 
A kick recovered by an onside player (sense 2).
quick kick 
A type of trick play: a punt from a running or passing formation, usually on second down. The play relies on catching the defence by surprise and using an onside player (sense 2) to recover the ball and gain a first down or even a touchdown. A rule change in the early 1970s that allowed the receiving team to block before gaining possession made the quick kick even more difficult to execute successfully, so it is rarely attempted today.
rouge 
An obsolete term for a single.
safety
  1. A defensive position on scrimmages, also called free safety. Typical formations include a single safety, whose main duty is to cover wide receivers. See also defensive back.
  2. A two-point score. The defence scores a safety when the offence carries or passes the ball into its own goal area and then fails to run, pass, or kick the ball back into the field of play.
short kick-off 
Deliberately kicking the ball just over 10 yards on a kick-off in an attempt to make an onside kick. Short kick-offs are usually directed towards the sideline (left sideline for a right-footed kicker) to give members of the kicking team time to get downfield to recover it. It is illegal procedure if the ball is recovered before it has gone 10 yards downfield.
single 
A one-point score. The kicking team scores a single when the ball is punted, drop kicked, or place kicked into the receiving team’s end zone (without scoring a field goal or hitting the goal post) and the receiving team fails to run or kick the ball back into the field of play. The single also is scored if the kick goes out of bounds in the end zone, except on a kickoff. On a kickoff, the single is scored only if the ball stays inbounds and is not run out of the zone, or if the defence puts the ball out of bounds in the end zone.
three-minute warning 
In the Canadian Football League, the three-minute warning is given when three minutes of game time remain on the game clock in the first and second halves of a game.
yard 
A yard is exactly 0.9144 metre.

Darik’s Boot and Nuke boot

Posted on April 26th, 2007 in Uncategorized by admin

Darik’s Boot and Nuke (commonly known as DBAN) is an open source project hosted on Sourceforge. The program is designed to securely wipe a hard disk until data is no longer recoverable, by overwriting the data with random numbers generated by Mersenne twister (a PRNG). The Gutmann method is included with DBAN.

DBAN can be booted from a floppy disk, CD, or USB flash drive and it is based on Linux. It supports IDE, SCSI and SATA hard drives.

Traditional engineering start

Posted on April 26th, 2007 in Uncategorized by admin

Traditional engineering, also known as sequential engineering, is the process of marketing, engineering design, manufacturing, testing and production where each stage of the development process is carried out separately, and the next stage cannot start until the previous stage is finished. Therefore the information flow is only in one direction, and it is not until the end of the chain that errors, changes and corrections can be relayed to the start of the sequence, causing estimated costs to be under predicted. This can cause many problems; such as time consumption due to many modifications being made as each stage does not take into account the next. This method is hardly used today, as the concept of concurrent engineering is more efficient.

AntiCMOS.B (computer virus) boot

Posted on April 26th, 2007 in Uncategorized by admin

AntiCMOS.B is a boot virus. It was isolated in mid-1995. Like AntiCMOS.A, AntiCMOS.B became common worldwide. However, this variant never reached the success level of the original, and is now consiered obsolete (the original is still occasionally reported).

Infected floppy disks contain the following text:

I am Li Xibin

Additionally, AntiCMOS.B attempts to play a tune, but this fails due to coding errors [1]. AntiCMOS.B is otherwise a typical boot virus, much like its predecessor.

Puss ‘N’ Boots is a 2003 studio album by Crash Test Dummies. The album began life as a Brad Roberts solo project. While the lyrics were written by Brad Roberts, most of the music was written by Stuart Cameron. Perhaps not coincidentally, this album is, musically-speaking, more conventional, less original. Ellen sang backing vocals and Dan played bass, though much of the music was performed by other musicians.

Sidney H. Liebson two-wheelers in developing

Posted on April 23rd, 2007 in Uncategorized by admin

Sidney H. Liebson (b. 1920) received his Ph.D. from the University of Maryland in 1947. His thesis was on the discharge mechanism of Geiger Muller counters. Liebson received a US Navy award for developing the first equipment used to identify enemy radar.

Liebson participated in atomic bomb testing in the Pacific, developing radiation detectors that were used to measure bomb characteristics. In a significant test, his detectors validated the feasibility of making the hydrogen bomb. At a time when electronics had not been able to make measurements with nanosecond accuracy, he developed several techniques to accomplish this accuracy for measuring organic fluorescence decay times and organic scintillation pulse widths by indirect means. His invention of the halogen counter occurred while he was working on his thesis.

Eudemian Ethics universally a

Posted on April 22nd, 2007 in Uncategorized by admin

The Eudemian Ethics (sometimes abbreviated EE in scholarly works) is a work of philosophy by Aristotle. Its primary focus is on Ethics. It is named for Eudemus of Rhodes, a pupil of Aristotle who may also have had a hand in editing the final work. Unlike the Magna Moralia, also called the Great Ethics, thought to be a summation written by Aristotle’s followers, the Eudemian Ethics are universally considered to be authentic.

The Eudemian Ethics usually receives less attention than Aristotle’s Nicomachean Ethics, and when scholars refer simply to The Ethics, they usually mean the latter. The Eudemian Ethics is shorter than the Nicomachean Ethics, (eight books as opposed to ten), and some of its most interesting passages are mirrored in the latter. Books IV, V, and VI of the Eudemian Ethics, for example, are identical to Books V, VI, and VII of the Nicomachean Ethics, and as a result some critical editions of the former include only Books I-III and VII-VIII (the omitted books being included in the publisher’s critical edition of the latter).
