Renard R.30. 

The Renard R.30 was a prototype trimotor airliner built in Belgium in 1931. It was a strut-braced high-wing monoplane of conventional design with a fully enclosed flight deck and separate passenger compartment. One engine was mounted on the nose, while the other two were mounted on the leading edges of the wings. Construction was metal throughout, skinned in plywood and fabric.

The R.30 was designed in response to a Belgian government requirement of 1929 for a long-range passenger transport aircraft to service Belgian Congo. The design met the specifications laid down, but by the time it flew in 1931, it was judged already obsolete. The single prototype, registered OO-AMK, was the only example built.

SWAT and WADS conferences. WADS, the Algorithms and Data Structures Symposium, is an international academic conference in the field of computer science, focusing on algorithms and data structures. WADS is held every second year, usually in Canada and always in North America. It is held in alternation with its sister conference, the Scandinavian Symposium and Workshops on Algorithm Theory (SWAT), which is usually held in Scandinavia and always in Northern Europe. Historically, the proceedings of both conferences were published by Springer Verlag through their Lecture Notes in Computer Science series. Springer continues to publish WADS proceedings, but starting in 2016, SWAT proceedings are now published by Dagstuhl through their Leibniz International Proceedings in Informatics.

History
The first SWAT took place in 1988, in Halmstad, Sweden. The first WADS was organised one year later, in 1989, in Ottawa, Ontario, Canada. Until 2007, WADS was known as the Workshop on Algorithms and Data Structures, and until 2008, SWAT was known as the Scandinavian Workshop on Algorithm Theory.

M·CORE. M·CORE is a low-power, RISC-based microcontroller architecture developed by Motorola (subsequently Freescale, now part of NXP), intended for use in embedded systems. Introduced in late 1997, the architecture combines a 32-bit internal data path with 16-bit instructions, and includes a four-stage instruction pipeline. Initial implementations used a 360nm process and ran at 50 MHz.

M·CORE processors employ a von Neumann architecture with shared program and data bus—executing instructions from within data memory is possible. Motorola engineers designed M·CORE to have low power consumption and high code density.

AGESA. AMD Generic Encapsulated Software Architecture (AGESA) is a procedure library developed by Advanced Micro Devices (AMD), used to perform the Platform Initialization (PI) on mainboards using their AMD64 architecture. As part of the BIOS of such mainboards, AGESA is responsible for the initialization of the CPU cores, chipset, main memory, and the HyperTransport controller.

History

AGESA was open sourced in early 2011, aiming to aid in the development of coreboot, a project attempting to replace PC's proprietary BIOS. However, such releases never became the basis for the development of coreboot beyond AMD's family 15h, as they were subsequently halted.

AGESA became particularly relevant with the AM4 platform, which AMD designed for futureproofing, and as of May 2019 has served as the base for three different generations of CPUs based on its Zen architecture. For each of these generations, a new branch of AGESA code has been released. AGESA versioning often runs separately for each of these three releases, so numbering regressions are bound to happen when going from one generation to the next.

The first version, named "Summit PI", launched in February 2017. It was targeted at the first generation Zen chips, and started with version 1.0.0.4. In December 2017, when Summit PI reached version 1.0.0.7, the branch was renamed to "Raven PI" (its version numbering was not reset), and it was released as the first version of AGESA to support Raven Ridge APUs.

The second version, supporting the Zen's second generation, known as Zen+, is named "Pinnacle PI", after the Ryzen processors' codename, Pinnacle Ridge. It launched in February 2018 with an initial version of 1.0.0.0a.

Then in March 2019, the third iteration of AGESA, named "ComboAM4 PI", was released, starting at version 0.0.7.0, introducing support for Zen 2-based processors.

"ComboAM4v2" supports Zen 3-based processors, while "ComboAM5PI" supports Zen 4-based processors in socket AM5 motherboards.

"ChagallWS PI" for the sWRX8 platform, supporting ThreadRipper Pro processors based on the Chagall architecture.

In April 2023, AMD announced plans to replace the aging AGESA codebase with a new open-source firmware called "AMD openSIL". The new firmware is expected to be ready by 2026.

IEC TC 25. IEC Technical Committee 25, "Quantities and units, and their letter symbols", was established in 1935. It is one of the technical committees of the International Electrotechnical Commission (IEC).

It merged with TC 24 and as a committee with "horizontal" responsibilities (i.e. covering matters of a wide-ranging nature and applicable by many “vertical” or product-oriented committees), it is in charge of all questions concerning the SI.

Among other standards it is responsible for parts 6, 13, 14, 15, 16, 17 of ISO/IEC 80000.

Node (UML). A node
in the Unified Modeling Language (UML) is a computational resource upon which UML artifacts may be deployed for execution.

There are two types of nodes: device nodes and execution environments.

 A device represents hardware devices: a physical computational resource with processing capability upon which UML artifacts may be deployed for execution. Devices may be complex (i.e., they may consist of other devices).

 An execution environment represents software containers (such as operating systems, JVM, servlet/EJB containers, application servers, portal servers, etc.) This is a node that offers an execution environment for specific types of components that are deployed on it in the form of deployable artifacts. 

Execution environments can be nested. Nodes can be interconnected through communication paths to define network structures. A communication path is an "association between two DeploymentTargets, through which they are able to exchange signals and messages".

Usage 
When modeling devices, it is possible to model them in several different ways:

 Name a device using the type and make, for instance "IBM RS6000", "HP 9000".
 Name a device using its intended function, for instance "Database Server", "High Speed Switch"
 Name a device using the operating system deployed on it, for instance "Linux Server", "Solaris Server".

Use tagged values to specify characteristics of devices / execution environments, for instance "Memory=2GB", "Disk Space=32GB", "Version=2.5.1".

Piper diagram. A Piper diagram is a graphic procedure proposed by Arthur M. Piper in 1944 for presenting water chemistry data to help in understanding the sources of the dissolved constituent salts in water. This procedure is based on the premise that cations and anions in water are in such amounts to assure the electroneutrality of the dissolved salts, in other words the algebraic sum of the electric charges of cations and anions is zero.

A Piper diagram is a graphical representation of the chemistry of a water sample or samples.

The cations and anions are shown by separate ternary plots. The apexes of the cation plot are calcium, magnesium and sodium plus potassium cations. The apexes of the anion plot are sulfate, chloride and carbonate plus hydrogen carbonate anions. The two ternary plots are then projected onto a diamond.  The diamond is a matrix transformation of a graph of the anions (sulfate + chloride/ total anions) and cations (sodium + potassium/total cations).

The Piper diagram is suitable for comparing the ionic composition of a set of water samples, but does not lend itself to spatial comparisons. For geographical applications, the Stiff diagram and Maucha diagram are more applicable, because they can be used as markers on a map. Colour coding of the background of the Piper diagram allows linking Piper Diagrams and maps

Water samples shown on the Piper diagram can be grouped in hydrochemical facies. The cation and anion triangles can be separated in regions based on the dominant cation(s) or anion(s) and their combination creates regions in the diamond shaped part of the diagram.

Aerolite (adhesive). Aerolite is a urea-formaldehyde gap filling adhesive which is water- and heat-resistant. It is used in large quantities by the chipboard industry and also by wooden boat builders for its high strength and durability. It is also used in joinery, veneering and general woodwork assembly. Aerolite has also been used for wooden aircraft construction, and a properly made Aerolite joint is said to be three times stronger than spruce wood.

History
Dr. Norman A. de Bruyne founded Aero Research Limited in 1934. The following year de Bruyne suggested that synthetic adhesives might play a part in aircraft production and engaged Cambridge University chemist R.E. Clark to investigate new adhesives for aircraft applications. The result was Aerolite, a urea-formaldehyde adhesive which unlike conventional glues of the time, resisted water and micro-organisms. Further research showed that gap-bridging hardeners incorporating formic acid enabled Aerolite to be used as an assembly adhesive. Aerolite was the first adhesive of its type to be invented and manufactured in Britain and used in resin-bonded plywood.

When World War II broke out, the small company began to grow.  Morris Motors used Aerolite and Aero Research's strip heating process to assemble Airspeed Horsa gliders, as did de Havilland on its Mosquito, as well as on other aircraft and also naval launches and patrol boats. On the Mosquito, Aerolite soon replaced the original "Beetle Cement" (known as "Kaurit" in Germany) synthetic resin adhesive used, after this glue was found not to stand up to the hot and humid climate in the Far East.

Following the end of the war, in 1948 de Bruyne sold control of Aero Research to the Swiss company Ciba, but remained as managing director until 1960.

Uses
Aerolite is currently marketed for use in boat building. Aerospace adhesives are used to assemble aircraft exteriors, engines, and interiors. Sealants seal the space between surfaces. Sealants increase the airtightness and watertightness of spaces. Aircraft have glues such as cockpit doors, fasteners, lights, etc. These glues are used in the general aviation industry. Aerospace adhesives and sealants are known for toughness, viscosity, longer durability and shorter cure times, depending on the requirements of aerospace applications.

Butch Steyn. Arron Cecil "Butch" Steyn is a South African politician, and a former Member of Parliament with the Democratic Alliance, and the Shadow Minister of Human Settlements from 2004 to 2012. He currently serves as a municipal councillor in the City of Johannesburg.

Early career
Before entering the political arena on a full-time basis, Butch practised as a Civil Engineer and was a partner in a national firm of Consulting Engineers before becoming Managing Director of his own practice.
Prior to that, he offered an architectural consulting service which led to the birth of a construction company. During his professional life, he specialised in the design of high rise structures such as office blocks, hotels, shopping centres, casinos and multi-storey apartment buildings. With the slump in the construction industry during the late 80s and early 90s,
he also did project management work, particularly in the oil/fuel industry for depot upgrades.

Political career
Butch was elected to the National Assembly in April 2004 and also served as a Democratic Alliance representative in the Gauteng Legislature from 1999 to 2004. He was also the first (and only) Democratic Party councillor in the Western Metropolitan Council of Johannesburg from 1994 to 1995 and later in the South-West Metropolitan Council (Roodepoort) between 1995 and 1999.

Steyn left parliament after the 2014 general election, but eventually returned to politics in November 2019, when he was sworn in as a PR councillor for the DA in Johannesburg.

Policy Issues
Butch Steyn has been a vocal critic of lack of oversight and monitoring in the Department of Human Settlements regarding the allocation of tenders and quality of work of contractors in the building of formal housing.

SPURV. SPURV, or Self-Propelled Underwater Research Vehicle, was an Autonomous Underwater Vehicle built in 1957 at the University of Washington's Applied Physics Laboratory. The research and development of this vehicle was funded by the United States Office of Naval Research (ONR), and it became the US Navy’s first autonomous underwater vehicle (AUV). The navy used a total of 7 SPURV vehicles until 1979.

Construction
The original engineers of SPURV were Bob Van Wagennen (mechanical) and Wayne Nodland (electrical).  Terry Ewart calculated the hydrodynamics design on a Berkeley EASE analog computer. SPURV was machined by Boeing from a forging of 7078-T6 aluminum.

Capability
SPURV had an operating depth of at least 3000 meters and a maximum depth of 3600 meters. It could go about 4-5 knots for about 4 hours. A propulsion battery consisting of 2 sets of 16 silver zinc cells connected in a parallel through diodes was the primary power source for SPURV. The battery provided a 24-volt, 200 ampere-hour supply. Secondary power came from 4 solid-state converters.

Acoustic signals from the accompanying research vessel guided SPURV in moving below the surface of the water. SPURV then generated models of underwater physical properties such as ocean currents and temperature.

Operations
SPURV was first operated from the ATA-195, the Navy Seagoing Tug Tatnuck in a 1957 cruise to Cobb Seamount. A tracking system had been built for the Tatnuck by Stan Murphy and Terry Ewart that could plot the range to SPURV on a strip chart recorder and the x-y position on a chart plotter.

The later SPURVS were utilized on 1-2 cruises per year by Terry Ewart and the Applied Physics Lab's Ocean Physics Department Engineers and Research Scientists, conducting about 20 month-long cruises in total to study small scale ocean variability including internal wave and fine-structure data, point source release dye diffusion at 1000 meters, and oceanographic data for acoustic transmission experiments.

In a few operations, two SPURVs were run at once in lock-step, 1 above the other or one beside the other at constant spacings.  This was to study spatial coherences of the small scale ocean structure. Most of the SPURVs operated with a vertical rake of temperature and conductivity sensors using what later became the Seabird sensors. In all cases, they could be tracked from the ship—usually with the capability of using a bottom or other reference system, and pitch, roll, and heading corrections for the ship.

The last operation of SPURV was in 1979 in the submarine wake study experiment. APL still has all 5 hulls, but they have not been used since then.

Henschel Hs 122. The Henschel Hs 122 was a German army cooperation/reconnaissance aircraft of the mid-1930s, radial-engined and with a parasol wing. Though only pre-production variants entered service, the Hs 122 led on to the Hs 126 which was produced in large numbers.

Development
The Hs 122 was the Henschel company's second aircraft, its first, the Hs 121 not being intended for production. It was designed in response to a Reich Air Ministry call for a multi-role army co-operation aircraft to replace the ageing Heinkel He 46.

The design emerged as a single-engine two-seat parasol wing machine with a fixed undercarriage. The wing centre section was carried above the fuselage on a series of short struts and the swept outer sections were braced to the lower fuselage with V struts. The wings were built around two metal spars and had metal-covered leading edges and upper surfaces with fabric elsewhere. The fuselage was an elliptical metal monocoque, with a metal-structured tail also metal covered apart from fabric control surfaces. The tailplane was mounted about halfway up the fin, supported by a parallel pair of struts. The spatted mainwheels were each mounted on V struts to the fuselage. The cockpits were open, with the pilot sitting below a cut-out in the wing trailing edge and the second crew member in a separate cockpit aft.

The first prototype, registered D-UBYN, was powered, like several other German aircraft of the time including the Messerschmitt Bf 109, by a Rolls-Royce Kestrel V-12-cylinder water-cooled engine; but the next prototype (D-UBAV) had a 460 kW (610 hp) Siemens Sh 22B 9-cylinder supercharged radial.

There were at least three prototypes, followed by a small number of pre-production Siemens-powered Hs 122B-0 aircraft which entered service in 1936. These were followed on the Henschel production lines at Schönefeld by the more powerful Hs 126.

Axel Aubert. Axel Aubert (11 December 1873 – 16 December 1943) was a Norwegian chemical engineer who served as Director-General of Norsk Hydro.

Biography
He was born in Kristiania (now Oslo, Norway). He was the son of  Otto Benjamin Andreas Aubert (1841–98) and  Hilda Thaulow (1846–1923).
After first studies at the Oslo Technical College, he then studied engineering at the University of Berlin and earned a doctorate in chemistry at the University of Basel in 1895.

He became the managing director of Engene Dynamitfabrik and Norsk Sprængstofindustri. In 1926 he was hired as Director-General (CEO) of Norsk Hydro. In 1940, while Norway was still neutral in World War II, Aubert was contacted by agents from French military intelligence regarding Norsk Hydro's production of heavy water (deuterium oxide) at its Vemork hydroelectric plant. Heavy water was an important material for Germany's nuclear weapon project and was only produced in any significant quantities at Vemork. He agreed to 'lend' Norsk Hydro's entire existing stock of heavy water to France for the duration of the war, observing that if Germany won the war he was likely to be shot. The French agents transported  of heavy water secretly to Oslo, to Perth in Scotland, and then to France.

Aubert retired as Hydro president in late 1941, but took over as the company's chairman and held this position until his death in 1943. Aubert emphasized the scientific and technological research. He was a member of the Executive Board of the Norwegian Industry Association from 1926 to 1934.

Honours 
Aubert was appointed Knight of the 1st Class of the Norwegian Order of St. Olav in 1928. He also held the Belgian Order of Leopold,  the French Legion of Honour,  the Danish Order of the Dannebrog and the Polish Order of Polonia Restituta.
