Zimbabwe Cricket
Zimbabwe Cricket (ZC), previously known as the Zimbabwe Cricket Union (ZCU) until 2004, is the governing body for the sport of cricket in Zimbabwe. Zimbabwe Cricket is a full member of the International Cricket Council (ICC), and administers the Zimbabwe national cricket team, organising Test tours, One-Day Internationals and Twenty20 Internationals with other nations. It also organises domestic cricket, including the Castle Logan Cup, the Coca-Cola Metbank Pro50 Championship and the Stanbic Bank 20 Series in Zimbabwe. History Zimbabwe cricket went through major upheaval during the 2000s. During the 2003 Cricket World Cup, senior team members Andy Flower and Henry Olonga staged their "black armband protest" at the "death of democracy" in Zimbabwe, a reference to the country's political situation. Both players subsequently retired from international cricket. In 2004, the majority of the remaining senior players quit the international game following a player protest trig ...

Zermelo
Ernst Friedrich Ferdinand Zermelo (; ; 27 July 187121 May 1953) was a German logician and mathematician, whose work has major implications for the foundations of mathematics. He is known for his role in developing Zermelo–Fraenkel axiomatic set theory and his proof of the well-ordering theorem. Furthermore, his 1929 work on ranking chess players is the first description of a model for pairwise comparison that continues to have a profound impact on various applied fields utilizing this method. Life Ernst Zermelo graduated from Berlin's Luisenstädtisches Gymnasium (now ) in 1889. He then studied mathematics, physics and philosophy at the University of Berlin, the University of Halle, and the University of Freiburg. He finished his doctorate in 1894 at the University of Berlin, awarded for a dissertation on the calculus of variations (''Untersuchungen zur Variationsrechnung''). Zermelo remained at the University of Berlin, where he was appointed assistant to Planck, under whos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zadoff–Chu Sequence
A Zadoff–Chu (ZC) sequence is a complex-valued mathematical sequence which, when applied to a signal, gives rise to a new signal of constant amplitude. When cyclically shifted versions of a Zadoff–Chu sequence are imposed upon a signal the resulting set of signals detected at the receiver are uncorrelated with one another. Description Zadoff–Chu sequences exhibit the useful property that cyclically shifted versions of themselves are orthogonal to one another. A generated Zadoff–Chu sequence that has not been shifted is known as a ''root sequence''. The complex value at each position ''n'' of each root Zadoff–Chu sequence parametrised by ''u'' is given by : x_u(n)=\text\left(-j\frac\right), \, where : 0 \le n < N_\text, : and , : , : , : . Zadoff–Chu sequences are CAZAC sequences ( [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zangger Committee
The Zangger Committee, also known as the Nuclear Exporters Committee, sprang from Article III.2 of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) which entered into force on March 5, 1970. Under the terms of Article III.2 International Atomic Energy Agency (IAEA) safeguards must be applied to nuclear exports. :Each State Party to the Treaty undertakes not to provide: (a) source or special fissionable material, or (b) equipment or material especially designed or prepared for the processing, use or production of special fissionable material, to any non-nuclear-weapon State for peaceful purposes, unless the source or special fissionable material shall be subject to the safeguards required by this Article. History Between 1971 and 1974, a group of 15 nuclear supplier states held a series of informal meetings in Vienna chaired by Professor Claude Zangger of Switzerland. The group's objective was to reach a common understanding on: (a) the definition of "equipment or materi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeptocoulomb
The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). It is defined to be equal to the electric charge delivered by a 1 ampere current in 1 second, with the elementary charge ''e'' as a defining constant in the SI. Definition The SI defines the coulomb as "the quantity of electricity carried in 1 second by a current of 1 ampere" by fixing the value of the elementary charge, . Inverting the relationship, the coulomb can be expressed in terms of the elementary charge: 1 ~ \mathrm = \frac = \frac ~ e. It is approximately and is thus not an integer multiple of the elementary charge. The coulomb was previously defined in terms of the ampere based on the force between two wires, as . The 2019 redefinition of the ampere and other SI base units fixed the numerical value of the elementary charge when expressed in coulombs and therefore fixed the value of the coulomb when expressed as a multiple of the fundamental charge.

Honda D Engine
The Honda D-series Straight-four engine, inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, Honda CRX, CRX, Honda Logo, Logo, Honda Stream, Stream, and first-generation Honda Integra, Integra. Engine displacement ranges between 1.2 and 1.7 liters. The D series engine is either SOHC or DOHC, and might include VTEC variable valve lift. Power ranges from in the Logo to in the Japanese market (JDM) Civic. D-series production commenced in 1983 (for the 1984 model year) and ended in 2005. D-series engine technology culminated with production of the D15B three-stage VTEC (D15Z7) which was available in markets outside of the United States. Earlier versions of this engine also used a single port fuel delivery system called PGM-CARB, signifying that the carburetor was computer controlled. D12 series engines (1.2 liter) D12A * Found in: ** 1986-1988 Honda City GG (Japanese Market) *** Displacement: 1237 cc (75.5 Cubic inch, cu in) *** Bo ...
