StartOS. StartOS (formerly Ylmf OS) is a discontinued Chinese Linux distribution.

StartOS is an operating system that is free and open-source software. In the beginning it was based on Ubuntu, but starting from version 4.0 it adopted custom package management (called YPK) and system installer, though the underlying live medium is still built using Ubuntu's Casper tool.
  Its user interface closely resembles that of Microsoft Windows XP.  The distribution was originally not available in the English language, though shortly after the initial release in late 2009 an English-language version of Ylmf OS was released.

Despite the very similar likeness to Windows XP's Luna theme—the default theme for Windows XP—Microsoft does not appear to be planning to take any sort of action against the operating system or its developers.

Ylmf OS 4.0 looks similar to Windows Vista, but also has a Mac OS X cursor scheme.

Pipe Cutting. Pipe cutting or pipe profiling is a mechanized industrial process that removes material from pipe or tubing to create a desired profile. Typical profiles include straight cuts, mitres, saddles and midsection holes. These complex cuts are usually required to allow a tight fit between two parts that are to be joined via arc welding.

Pipe cutting is used in industries such as offshore operations, pipe processing, shipbuilding and pressure vessel manufacture. This technology is valued for its ability to produce the intricate cuts and profiles often required in these fields. Common applications include pipework, offshore jackets, steel frameworks, cranes, and demolition of structures offshore.

Hot cutting

Hot cutting refers to a process in which materials are cut using a thermal torch. One of the most common techniques is oxy-fuel gas cutting, which is used extensively for cutting carbon and low-alloy steels. However, its efficiency diminishes as the alloy content of the material increases, limiting its applicability for high-alloy steels. Arc-based cutting methods are used for cutting these materials. Among these, plasma arc cutting is the most commonly employed technique, owing to its precision and ability to cut through high-alloy steels efficiently. Thermal cutting creates a shallow region contaminated material adjacent to the cut surfaces - the heat affected zone. For some applications it is necessary to remove this material by mechanical means, such as grinding or machining,  prior to use or further fabrication by welding. 

The cutting torch can be integrated into a  machine to perform precision cutting operations. In multi-axis machines, the movement of the axes is powered by electric motors and synchronized to guide the torch and the pipe being cut along a programmed path, resulting in the desired cutting profile. The synchronization of axes is accomplished either mechanically, via cams, levers and gears, or electronically with  microprocessors , which is computer numerical control (CNC).

Cold cutting

Where the high temperatures and sources of ignition required by hot cutting are not desirable, air- or hydraulically-powered pipe cutting machines are used. These comprise a clamshell or chain-mounted cutting head holding a tool steel and feed mechanism which advances the tool a set amount per revolution round the pipe. Tools may be styled to cut and/or prepare the bevel for welding in a single or multiple passes.

High pressure abrasive water jets can be used for cold cutting. This technology is employed for the decommissioning of offshore structures.

Drilling riser. A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. Drilling risers are categorised into two types: marine drilling risers used with subsea blowout preventer (BOP) and generally used by floating drilling vessels; and tie-back drilling risers used with a surface BOP and generally deployed from fixed platforms or very stable floating platforms like a spar or tension leg platform (TLP).

Marine drilling riser
A marine drilling riser has a large diameter, low pressure main tube with external auxiliary lines that include high pressure choke and kill lines for circulating fluids to the subsea blowout preventer (BOP), and usually power and control lines for the BOP.
The design and operation of marine drilling risers is complex, and the requirement for high reliability means an extensive amount of engineering analysis is required.

When used in water depths greater than about 20 meters, the marine drilling riser has to be tensioned to maintain stability. A marine riser tensioner located on the drilling platform provides a near constant tension force adequate to maintain the stability of the riser in the offshore environment. The level of tension required is related to the weight of the riser equipment, the buoyancy of the riser, the forces from waves and currents, the weight of the internal fluids, and an adequate allowance for equipment failures.

To reduce the amount of tension required to maintain stability of the riser, buoyancy modules, known in the industry as 'buoyancy cakes', are added to the riser joints to make them close to neutrally buoyant when submerged.

The international standard ISO 13624-1:2009 covers the design, selection, operation and maintenance of marine riser systems for floating drilling operations. Its purpose is to serve as a reference for designers, for those who select system components, and for those who use and maintain this equipment. It relies on basic engineering principles and the accumulated experience of offshore operators, contractors, and manufacturers.

Tie-back drilling riser
A tie-back riser can be either a single large-diameter high pressure pipe, or a set of concentric pipes extending the casing strings in the well up to a surface BOP.

Transener. Transener (BCBA: TRAN) is the leading Argentine company in the transmission of extra high voltage electric power.

The company owns the national extra high voltage transmission network, comprising almost 8,800 kilometers (5,500 mi) of transmission lines. Another 5,500 miles of lines belong to the distribution network and subsidiary, Power Distribution Transport Company of the Province of Buenos Aires S.A. (Transba S.A.).

Purchasing the power transmission network from a State enterprise, Compañia de Tranporte de Energía en Alta Tensión, upon its 1993 privatization, Transener operates 95% of the high voltage lines in Argentina, and is a subsidiary of Pampa Energía, the largest private electricity producer in the country. Controlled by local conglomerate Pérez Companc until 2003, Pampa Enegía gained control of the company in 2004, when it bought a controlling stake from Brazilian energy giant Petrobras.

Build-A-Bird. Build-A-Bird (1986 or earlier) was educational software for the Unisys ICON II public school computer. It may have appeared on the ICON I or Unisys ICON III.

Overview
Build-A-Bird was designed and developed by Ergonomics Lab, University of Toronto. Gameplay revolved around creating a bird by choosing from a selection of different body parts such as stork-like legs, short legs adapted to alighting on various natural surfaces, or predatory talons. Beak type and wing type were also among the changeable body part selections in Build-A-Bird. Upon selecting your preferred, various body part types the game would provide one or several real life birds that fit your selections. What happened next in the game involved educational material about your bird's range and habitat. The visual representations of the birds, their body parts and the bird habitats were in colour and vivid for the time but lacked animation.

Bell Airacobra I AH574. AH574 was a Bell Airacobra I used by the Royal Navy for test work during and after the Second World War

Initial history 
AH574 was initially ordered in 1940 for the Royal Air Force (RAF) as part of the Airacobra I serial number block AH570–AH739 (No. 601 Squadron RAF). When the Airacobra type was rejected by the RAF, AH574 was transferred to the Royal Navy for test work.

Test work 
On 4 April 1945, AH574 became part of aviation history when test pilot Captain Eric "Winkle" Brown landed it on the flight deck of HMS Pretoria Castle—the first carrier landing made by an aircraft with retractable tricycle gear—due to a declared emergency during initial trials for landings on rubber decks planned for future carriers.

In his autobiography, Captain Brown described the circumstances thus:I had already collected a few 'firsts' in aviation, and I rather wanted to be the first pilot to put a tricycle aircraft down on a flight deck. The Airacobra was not officially cleared for such a landing, but the boffins had told me privately that it would probably take the strain.This was not on the official programme at all, but I hoped that I could persuade Captain Caspar John of the Pretoria Castle to turn a blind eye to what I had in mind. I wrote to him beforehand and asked him if he would be prepared to take me aboard in the event of sudden engine trouble. He at once saw what I was after, of course, and was good sport enough to go along with it. He suggested that it might be a good idea if my engine trouble occurred on my last approach.Strangely enough it did. I began my approach, then, just for the record, called up the ship and complained that my engine was running rough. Would they accept me? Back came Captain John's instant 'affirmative'. I put the hook down, and caught the wire with no trouble at all. The trouble started when the time came to take off, as the Airacobra had a long take-off run—which was one of the reasons behind the type's rejection by the RAF—and 'Winkle' only managed to get airborne because Pretoria Castle was steaming full speed ahead at the time.

Fate
In March 1946, a visiting Bell test pilot oversaw laminar flow experiments being conducted with Bell P-63 Kingcobras.Just for a laugh I asked him to test my old Bell Airacobra, which I had been using for so many hops around the country. He took off, did one very quick circuit, and came back ashed-faced. 'I have never,' he said, 'flown in an aeroplane in such an advanced state of decay. This machine should be scrapped forthwith.' So, on 28th March, I went up for a last aerobatic session in her, then bade a sentimental farewell. The last laugh was on me.   AH574 was duly scrapped shortly afterward, and Brown was later given a Fieseler Storch as a replacement.

Explosive-driven ferroelectric generator. An explosive-driven ferroelectric generator (EDFEG, explosively pumped ferroelectric generator, EPFEG, or FEG) is a compact pulsed power generator, a device used for generation of short high-voltage high-current pulse. The energies available are fairly low, in the range of single joules, the voltages range in tens of kilovolts to over 100 kV, and the powers range in hundreds of kilowatts to megawatts. They are suitable for delivering high voltage pulses to high-impedance loads and can directly drive radiating circuits.

ECFEGs operate by releasing the electrical charge stored in the poled crystal structure of a suitable ferroelectric material, e.g. PZT, by an intense mechanical shock. They are a kind of phase transition generators.

The structure of an EDFEG is generally a block of a suitable high explosive, accelerating a metal plate into a target made of ferroelectric material.

FEGs find multiple uses due to their compact character; charging banks of capacitors, initiation of slapper detonator arrays in nuclear weapons and other devices, driving nuclear fusion reactions, powering pulsed neutron generators, seed power sources for stronger pulse generators (e.g. EPFCGs), electromagnetic pulse generators, electromagnetic weapons, vector inversion generators, etc.

A 2.4 megawatt HERF generator (an EDFEG with a pulse forming network directly driving a dipole antenna) with peak output frequency at 21.4 MHz was demonstrated.

Breda Ba.75. The Breda Ba.75 was an Italian prototype two-seat reconnaissance and ground-attack aircraft designed and built by the Società Italiana Ernesto Breda. Only one aircraft was built and the type did not enter production.

Development
Based on the design of the earlier Ba.65 the Ba.75 was slightly larger and was a mid-wing cantilever monoplane and unlike the Ba.65 had a fixed tailwheel landing gear. The Ba.75 was powered by a 900 hp (670 kW) Isotta-Fraschini K.14 radial piston engine. The bottom and lower sides of the fuselage were glazed to allow observation of the ground. The only Ba.75 was built and test flown in 1939.
