Mesa (programming language)

Mesa is an innovative programming language (superseded by the Cedar language) developed in the late 1970s at the Xerox Palo Alto Research Center in Palo Alto, California, United States. The language name was a pun based upon the programming language catchphrases of the time, because Mesa is a "high level" programming language.

Mesa is an ALGOL-like language with strong support for modular programming. Every library module has at least two source files: a definitions file specifying the library's interface plus one or more program files specifying the implementation of the procedures in the interface. To use a library, a program or higher-level library must "import" the definitions. The Mesa compiler type-checks all uses of imported entities; this combination of separate compilation with type-checking was unusual at the time.

Mesa introduced several other innovations in language design and implementation, notably in the handling of software exceptions, thread synchronization, incremental compilation, and more.

Wave

In physics, a wave is an oscillation accompanied by a transfer of energy that travels through space or mass. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium—that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations.

There are two main types of waves. Mechanical waves propagate through a medium, and the substance of this medium is deformed. The deformation reverses itself owing to restoring forces resulting from its deformation. For example, sound waves propagate via air molecules colliding with their neighbors. When air molecules collide, they also bounce away from each other (a restoring force). This keeps the molecules from continuing to travel in the direction of the wave.

The second main type of wave, electromagnetic waves, do not require a medium. Instead, they consist of periodic oscillations of electrical and magnetic fields originally generated by charged particles, and can therefore travel through a vacuum. These types of waves vary in wavelength, and include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Park West, Dublin

Park West (Irish: Páirc an Iarthair) is a large business campus within greater Ballyfermot, notably Cherry Orchard, Dublin, Ireland, with some residential development.

There are over 300 companies with 10,000 employees.

Location and content

Located just inside the M50 orbital motorway in west Dublin, the development comprises several million square metres of office and retail space, along with an Aspect hotel, a private hospital, and three apartment complexes.

Park West is in the administration of Dublin City Council, and Dublin postal districts Dublin 10 and Dublin 12, chiefly the latter.

Art

Park West is home to Europe's tallest wind and water mobile sculpture, Wave by Angela Conner. It is a 39.3 metre (129 feet) tall sculpture made of polystyrene covered with layers of carbon resin. It is fixed into a 7.6 metre (25 foot) pit filed with 9.5 tonnes of lead.

Transport

The campus is accessible by road (primarily the (New) Nangor Road, as well as Killeen Road and Cloverhill), bus (routes 79A and 151) and rail at the Park West and Cherry Orchard railway station. At a moderate distance to the south is the Kylemore stop on the Luas red line.

Wave (Antonio Carlos Jobim album)

Wave is the third album by Antônio Carlos Jobim, released in 1967 on A&M Records. It is known as Jobim's most successful album to date (# 5 US JAZZ ALBUMS 1967,# 114 US ALBUMS 1968), and it was listed by Rolling Stone Brazil as one of the 100 best Brazilian albums in history.
