Vanguard (Nigeria)

The Vanguard is a daily newspaper published by Vanguard Media, based in Lagos, Nigeria.

Vanguard Media was established in 1983 by veteran journalist Sam Amuka-Pemu with three friends. The paper has an online edition. The newspaper is one of the few in Nigeria that is considered independent of political control, the others being Thisday, The Punch, The Sun and The Guardian. In June 1990, the paper was briefly suspended by Col. Raji Rasaki, Military Governor of Lagos State.

In December 2008 the US-based Pointblanknews.com published a story that alleged the wife of the publisher of Vanguard Newspapers was involved in a ritual killing. The Vanguard took the reporter to court, claiming he was attempting extortion. In December 2009, a Niger Delta peace activist commended Vanguard Newspapers for its reporting on the government's intentions, which he said helped persuade the militants to accept amnesty.

Ulmus 'Morton Plainsman' Vanguard

Ulmus 'Morton Plainsman' (selling name Vanguard™) is a hybrid cultivar raised by the Morton Arboretum from a crossing of the Siberian Elm U. pumila (female parent) and a specimen of the Japanese Elm U. davidiana var. japonica grown from openly-pollinated seed donated by the Agriculture Canada Research Station at Morden, Manitoba.

Description

Vanguard has modest upright growth, increasing in height by an average of 0.8 m in an assessment at U C Davis, with leaves much the same size and colour of the American Elm. However, its performance in the southern United States has not impressed, and it was dismissed, along with its Morton stablemates Commendation and Triumph, as "ugly" by Michael Dirr, Professor of Horticulture at the University of Georgia , on account of its "wild" growth and splaying branches.

Pests and diseases

Although resistant to Dutch elm disease, Vanguard remains very susceptible to pests such as the elm-leaf beetle Xanthogaleruca luteola , Japanese beetle, and cankerworms.

Vanguard (synthesizer)

Vanguard is a VSTi and AU software synthesizer by German independent publisher reFX.

Released in 2004, it is a virtual analog synthesizer with three oscillators, 32 waveforms, up to 10-times unison, a filter with a number of frequency responses, delay and reverb effects and stereo pattern controlled noise gate and arpeggiator, making this plugin useful among the electronic dance music producers. Most functions can be automated, such as cutoff frequencies, resonance, ADSR, and LFO. Vanguard works with any VST-capable host and features the Trancegate and Arpeggiator tools. The audio engine and a part of the factory sounds from Vanguard were programmed by Markus Krause from Tone2 Audiosoftware.

This synthesizer is used by many electronic dance music producers, however is not as prevalent as reFX's Nexus 2 ROM plugin. Nexus2 is so called because it replaced the upgraded 2007 package for Vanguard called "Nexus ROM" in early 2008.

Zenith (building)

The Zenith is a culture and exhibition centre, converted from an old railway reparation hall, located in Freimann, Munich, Germany.

The centre hosts concerts, fairs, company presentations and parties. The centre can hold up to six thousand people and has a floor area of 5046 m². The main stage is 24×16 metres in area. Its capacity is approximately 7,000 people

History

The building is of a unique architectural style, and formerly served as a railway construction and reparation hall. It was originally built from 1916 to 1918. The building is protected.

Zenith camera

A zenith camera is an astrogeodetic telescope used today primarily for the local surveys of Earth's gravity field. Zenith cameras are designed as transportable field instruments for the direct observation of the plumb line (astronomical coordinates) and vertical deflections.

Instrument

A zenith camera combines an optical lens (about 10–20 cm aperture) with a digital image sensor (CCD) in order to image stars near the zenith. Electronic levels (tilt sensors) serve as a means to point the lens towards zenith. Zenith cameras are generally mounted on a turnable platform to allow star images to be taken in two camera directions (two-face-measurement). Because zenith cameras are usually designed as non-tracking and non-scanning instruments, exposure times are kept short, at the order of few 0.1 s, yielding rather circular star images. Exposure epochs are mostly recorded by means of the timing-capability of GPS-receivers (time-tagging).

Data processing

Depending on the CCD sensor - lens combination used, few 10s to 100s of stars are captured with a single digital zenith image. The positions of imaged stars are measured by means of digital image processing algorithms, such as image moment analysis or point spread functions to fit the star images. Star catalogues, such as Tycho-2 or UCAC-3 are used as celestial reference to reduce the star images. The zenith point is interpolated into the field of imaged stars, and corrected for the exposure time and (small) tilt of the telescope axis to yield the direction of the plumb line.

Zenith (disambiguation)

The zenith is the point in the sky that appears directly above the observer (opposite: nadir).
