Hughes & Kettner. Hughes & Kettner is a German manufacturer of instrument amplifiers, cabinets and effects boxes.

History
The company was founded in Neunkirchen in 1984 by two brothers, Hans and Lothar Stamer, and moved to St. Wendel three years later.

It is cited as a "long and good standing reputation as a maker of solidly performing tube amplifiers".

In 1989, Hughes & Kettner offered the first realistic  speaker emulation device, the Red Box, providing the sound of a speaker without needing a microphone. In 1997, the company designed the Rotosphere, a tube-powered effects pedal simulating the sound of a rotary cabinet, similar to a Leslie, but in a much smaller form factor. It has been used by guitar players but also by some keyboard players, such as Jon Lord. In 2011, Music Radar named the Rotosphere as one of the best modulation and filter pedals of all time.

The company is actively producing new models, both tube and solid-state amplifiers. In 2020, the company released the 50W Spirit Nano amplifier head, which combines a transistor amplifier with a Red Box Leslie simulator. The era 1 and era 2 are general purpose amplifiers that are suitable for acoustic guitars and microphones.

Notable users
Notable users of Hughes & Kettner products include Rush's Alex Lifeson and Kiss' Tommy Thayer, who have signature amplifiers by the company (The TriAmp MKII Alex Lifeson and the Duotone Tommy Thayer). Marillion's Steve Rothery is a longtime user of the Rotosphere and prefers it to other Leslie simulators.

Other Hughes and Kettner users are Joel Stroetzel who has used the company's Rotosphere, Adam Dutkiewicz, Joe Bonamassa, Peredur ap Gwynedd who uses a GrandMeister 36, Nuno Bettencourt, Tony Macalpine, Michael Wilton and Allan Holdsworth.

Hughes & Kettner made a custom rig of steampunk styled guitar amplifiers for Rush's Time Machine Tour in 2010.

Point of appearance. Point of appearance is a generic term for any point in a telephone/data circuit from which a technician can test or pull stats. Some appearances are virtual, such as a Digital cross connect system computer terminal. Others are physical, like a punch down COSMIC frame where a technician can place a test set, or a heat coil socket. In the outside plant there is an appearance at the cross box, pedestal, and network interface device. The ultimate appearance is the telephone or other customer premises equipment (CPE).

Karl Friedrich Plattner. Karl Friedrich Plattner (2 January 1800 – 22 January 1858) was a German metallurgical chemist.

He was born at Kleinwaltersdorf, near Freiberg in the Electorate of Saxony, on 2 January 1800. His father, though only a poor working miner, found the means to have him educated first at the Bergschule (mining school) and then at the Bergakademie of Freiberg. After he had completed his courses there in 1820 he obtained employment, chiefly as an assayer, in connexion with the royal mines and metal works. Having taken up the idea of quantitative mouth blowpipe assaying, which was then almost unknown, he succeeded in devising dependable methods for all the ordinary useful metals.  In particular his modes of assaying for nickel and cobalt quickly found favour with metallurgists. He also devoted himself to the improvement of qualitative blowpipe analysis, and summed up his experience in a treatise Die Probierkunst mit dem Löthrohr (1835), which became a standard authority.

In 1840 he was made chief of the royal department of assaying. Two years later he was deputed to complete a course of lectures on metallurgy at the Bergakademie in place of W. A. Lampadius (1772–1842), whom he subsequently succeeded as professor. He died at Freiberg on 22 January 1858.

In addition to many memoirs on metallurgical subjects he also published Die metallurgischen Rostprocesse theoretisch betrachtet, and posthumously Vorlesungen über allgemeine Hüttenkunde.

Plan 9 from User Space. Plan 9 from User Space (also plan9port or p9p) is a port of many Plan 9 from Bell Labs libraries and applications to Unix-like operating systems.  Currently it has been tested on a variety of operating systems, including Linux, macOS, FreeBSD, NetBSD, OpenBSD, Solaris and SunOS. The project's name is a reference to the 1950s Ed Wood film Plan 9 from Outer Space.

A number of key applications have been ported, as have programs used by the system itself, along with the requisite libraries from Plan 9. All of these have been made to work on top of a Unix-like environment instead of their native Plan 9. Some of the most significant ported components are:
 rc – The Plan 9 shell
 sam – A text editor
 acme – A combination of text editor and graphical shell especially useful to programmers
 mk – A tool for building software, analogous to the traditional Unix make utility
 plumber – An interprocess messaging facility
 Venti – A network storage system that permanently stores data blocks

Erik Palmén. Erik Herbert Palmén (31 August 1898 – 19 March 1985) was a Finnish meteorologist, born in Vaasa. He worked at the University of Chicago in the Chicago school of meteorology (started by Carl-Gustaf Rossby) on cyclones and weather fronts with Vilhelm Bjerknes. He contributed to the explanation of the dynamics of the jet stream and the analysis of data collected by radiosondes; his preprocessed and quality checked datasets were widely used by other researchers. Palmen was a multisided researcher who published articles in meteorology, geophysics and oceanography. The 1969 book by Palmen and Chester W. Newton, "Atmospheric Circulation Systems: Their Structure and Interpretation", is still used as lecture material in the universities around the world.

Palmen was the director of Finnish Institute of Marine Research, a professor in Helsinki University and a member of the Finnish Academy of Arts and Letters. His nickname by students, friends and colleagues was Maestro  and he was well known for his passion for cigars and interest of effects of weather on agriculture.

Palmen received the Buys Ballot Medal of Royal Netherlands Academy of Arts and Sciences in 1964. By then, when more computing power was available and the first steps of numerical weather prediction were taken, the value of the work done by the Chicago School 10–20 years earlier was really appreciated.

In 1969 he was awarded the prestigious International Meteorological Organization Prize from the World Meteorological Organization.

ISO 10303-28. For product and manufacturing information, STEP-XML is a short term for ISO 10303-28, Industrial automation systems and integration—Product data representation and exchange—Part 28: Implementation methods: XML representations of EXPRESS schema and data. STEP-XML specifies the use of the Extensible Markup Language (XML) to represent EXPRESS schema (ISO 10303-11) and the data that is governed by those EXPRESS schema. It is an alternative method to STEP-File for the exchange of data according to ISO 10303.

The following specifications are within  the scope of ISO 10303-28:
 Late Bound XML markup declaration set, independent of all EXPRESS schemas, to describe the XML representation of the data governed by each schema
 Early Bound XML markup declaration sets, for each of the schemas, to describe the XML representation of the data governed by that specific schema
 The mapping between the schema-specific and schema-independent XML markup declarations 
 The form of XML documents containing EXPRESS schemas and/or data governed by EXPRESS schemas
 The XML markup declarations that enables XML representation of EXPRESS schemas
 The representation of EXPRESS primitive data type values as element content and as XML attribute values.

The following specifications are outside the scope of ISO 10303-28:
 XML markup declarations that depend on the semantic intent of the corresponding EXPRESS schema
 The mapping from an XML markup declaration to an EXPRESS schema.  Note:  Given an XML markup declaration set and its corresponding data set(s), it is possible to create an EXPRESS schema that captures the semantic intent of the data. However, this would requires an understanding of the meaning and use of the data that may not be captured by the XML markup declarations.
 The mapping from an XML representation of an EXPRESS schema back to the initial EXPRESS schema 
 The mapping from the XML markup declarations that have been derived from an EXPRESS schema back to the initial EXPRESS schema 
 The mapping of the final use of an XML schema.

Floris Takens. Floris Takens (12 November 1940 – 20 June 2010) was a Dutch mathematician known for contributions to the theory of chaotic dynamical systems.

Together with David Ruelle, he predicted that fluid turbulence could develop through a strange attractor, a term they coined, as opposed to the then-prevailing theory of accretion of modes. The prediction was later confirmed by experiment. Takens also established the result now known as the Takens's theorem, which shows how to reconstruct a dynamical system from an observed time-series. He was the first to show how chaotic attractors could be learned by neural networks.

Takens was born in Zaandam in the Netherlands. He attended schools in The Hague and in Zaandam before serving in the Dutch army for one year (1960–1961). At the University of Amsterdam, he concluded his undergraduate and graduate studies. He was granted a doctorate in mathematics in 1969 under the supervision of Nicolaas Kuiper for a thesis entitled The minimal number of critical points of a function on a compact manifold and the Lusternik–Schnirelmann category.

After his graduate work, Takens spent a year at the Institut des Hautes Études Scientifiques, in Bures-sur-Yvette, near Paris, where he worked with David Ruelle, René Thom, and Jacob Palis. His friendship with Palis has taken him many times to the Instituto de Matemática Pura e Aplicada (IMPA) in Rio de Janeiro, Brazil. Their collaboration produced several joint publications.

Takens was a professor at the University of Groningen, in Groningen, the Netherlands from 1972 until he retired from teaching in 1999.

Takens was member of:
 The Royal Netherlands Academy of Arts and Sciences (since 1991)
 The Brazilian Academy of Sciences (since 1981), and
 The editorial board for the Springer-Verlag's Lecture Notes in Mathematics.

ITnet. ITnet (Institute of Technology Network) was a PoS based multi Mbit/s network created for the Institutes of Technology in Ireland. ITnet used 45 Mbit/s links to each of the institutions and an international link of 310 Mbit/s via HEAnet.

The system was proposed in 1991 between Regional Technical College, Cork and Regional Technical College, Carlow, as they were then called. In 1993 an agreement was reached to create RTCnet. The system was running by 1994 with its hub in University College Dublin and service management at Carlow. All Regional Technical Colleges were connected to the system.

In 1998 RTCnet became ITnet to reflect the change in status of the Regional Technical College system to Institutes of Technology. The hub of the system and service management moved to Institute of Technology, Tallaght where an international link was provided via HEAnet.

ITnet was incorporated into HEAnet during 2007 and 2008 and has now ceased to exist as an independent network for the IoTs. All internet services are now provided directly to the Institutes by HEAnet.

Business Object Notation. In software engineering, Business Object Notation (BON) is a method and graphical notation for high-level object-oriented analysis and design.

The method was developed between 1989 and 1993 by Jean-Marc Nerson and Kim Waldén as a means of extending the higher-level concepts of the Eiffel programming language. It claims to be much simpler than its competition - the Unified Modeling Language (UML) - but it didn't enjoy its commercial success.
