  2. Hypixel - Wikipedia

    en.wikipedia.org/wiki/Hypixel

    Hypixel Network, [3] simply known as Hypixel, is a Minecraft server that hosts minigames. It was released on April 13, 2013 by Simon "hypixel" (name of player is not written like the name of the server, but with a lower h (see list of admins)) Collins-Laflamme and Philippe Touchette, and is managed and run by Hypixel Inc. [4] Hypixel is only available on the Java Edition of Minecraft, [5] but ...

  3. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Energy conversion efficiency depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle.

  4. House Energy Rating - Wikipedia

    en.wikipedia.org/wiki/House_energy_rating

    It is used in more than 18 states of US. This scheme uses a 100 points scale of efficiency and it is further divided into 10 categories of star rating which ranges from one star to five star plus. In this rating scheme a higher star rated house represents higher energy efficiency of the house. ENERGY STAR

  5. Electrical efficiency - Wikipedia

    en.wikipedia.org/wiki/Electrical_efficiency

    A premium efficiency electric motor: more than 90% (see Main Article: Premium efficiency). A large power transformer used in the electrical grid may have efficiency of more than 99%. Early 19th century transformers were much less efficient, wasting up to a third of the energy passing through them. [citation needed]

  6. Engine efficiency - Wikipedia

    en.wikipedia.org/wiki/Engine_efficiency

    The efficiency of internal combustion engines depends on several factors, the most important of which is the expansion ratio. For any heat engine the work which can be extracted from it is proportional to the difference between the starting pressure and the ending pressure during the expansion phase.

  7. Efficiency (statistics) - Wikipedia

    en.wikipedia.org/wiki/Efficiency_(statistics)

    In statistics, efficiency is a measure of quality of an estimator, of an experimental design, [1] or of a hypothesis testing procedure. [2] Essentially, a more efficient estimator needs fewer input data or observations than a less efficient one to achieve the Cramér–Rao bound.

  8. Ideal machine - Wikipedia

    en.wikipedia.org/wiki/Ideal_machine

    In this case, the mechanical efficiency is 100%. Mechanical efficiency is the performance of the machine compared to its theoretical maximum as performed by an ideal machine. The mechanical efficiency of a simple machine is calculated by dividing the actual power output by the ideal power output. This is usually expressed as a percentage.

    en.wikipedia.org/wiki/Mineplex

    Mineplex was a Minecraft minigame server created in 2013 by Gregory Bylos and Jarred van de Voort. [4] [5] In 2016, Mineplex had millions of unique players monthly. [6]At its peak, the server had around 20,000 concurrent players at any given time. [7]
