Aims (album)

Aims is the fifth studio album by American pop singer-songwriter Vienna Teng. Produced by Cason Cooley, the work was released on September 24, 2013.

The album brought Teng four awards in the thirteenth annual Independent Music Awards: Adult Contemporary Album, A Cappella Song (for "The Hymn of Acxiom"), Pop Song (for "Level Up"), and Social Action Song (for "Level Up"). This was the first time an artist received four awards in one year.

Background

The album was made while Teng was in graduate school at the University of MichiganErb Institute for Global Sustainable Enterprise. In previous albums, Teng relied almost solely on the piano, but for this album, Teng relied largely on Cooley's sound library with tracks ranging from African percussion to an orchestra of instruments.

Production

The album was produced by Cason Cooley, who has worked on albums for Chris Mason and Mindy Gledhill.

Track listing

Pușcă Automată model 1986

The Pușcă Automată model 1986 (Automatic Rifle Model 1986, abbreviated PA md. 86 or simply md. 86) is the standard assault rifle used by the Romanian Military Forces and manufactured in Cugir, Romania by the RomArm S.A. firm, located in Bucharest. The export name for this variant is the AIMS-74.

History

As the Soviet Union switched from the 7.62×39mm caliber AKM to the 5.45×39mm caliber AK-74, it encouraged other nations of the Warsaw Pact to follow suit.

By the mid 80s, Romania decided to switch calibers, however it was decided that the new rifle would be developed independently, and not represent a clone of the Soviet AK-74. In doing so, the PA md. 86 has several anachronistic AKM elements that were found only on the prototype Soviet AK-74.

Features

The most easily recognized AKM feature is the gas block design (45 degree versus 90 degree). Incidentally, although the gas block is purely AKM, the gas vent in the barrel did change to a 90-degree design to minimize bullet shearing (a problem with early Soviet AK-74s with 45-degree gas blocks). This means the Romanian PA md. 86 has a double-angle gas port, which makes it much harder to clean the gas vent. This variant also uses the AK-47 rear trunnion, and thus the siderail is lengthened.

Science and engineering

Wheel

A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the main components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel and flywheel.

Common examples are found in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity, or by the application of another external force or torque.

Etymology

The English word wheel comes from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *k^wek^wlo-, an extended form of the root *k^wel- "to revolve, move around". Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, the latter both meaning "circle" or "wheel".

Parallel curve

A parallel of a curve is the envelope of a family of congruent circles centered on the curve. It generalises the concept of parallel lines. It can also be defined as a curve whose points are at a fixed normal distance from a given curve. These two definitions are not entirely equivalent as the latter assumes smoothness, whereas the former does not.

A parallel curve is also called an offset curve and this is the preferred term in CAGD. (In other geometric contexts, the term offset can also refer also to translation.) Offset curves are important for example in numerically controlled machining, where they describe for example the shape of the cut made by a round cutting piece of a two-axis machine. The shape of the cut is offset from the trajectory of the cutter by a constant distance in the direction normal to the cutter trajectory at every point.

In the area of 2D computer graphics known as vector graphics, the (approximate) computation of parallel curves is involved in one of the fundamental drawing operations, called stroking, which is typically applied to polylines or polybeziers (themselves called paths) in that field.
