Adaptive architecture. Within reconfigurable computing, an Adaptive architecture is a system which changes its structure, behaviour or resources according to demand. The adaptation made is usually [always?] to non-functional characteristics rather than functional ones. 

Something of a misnomer, because the thing that adapts is the working system, rather than the (more abstract) architecture which defines the adaptability that is required of that system.

Adaptive software architecture: Used by programmers in relation to a program. An adaptive algorithm "is an algorithm which changes its behavior based on the resources available. For example… in the C++ Standard Library, the stable partition [program] acquires as much memory as it can get (up to what it would need at most) and applies the algorithm using that available memory."

Adaptive infrastructure architecture: Used by infrastructure engineers in relation to the configuration of processors. The computing resources used by applications (the partition size, or the number of servers in a cluster, or the share of a processor, or the number of processes) are configured so that they shrink or grow with demand.

Adaptive business architecture: Could also be used (for example) in connection with a workflow system that assigns human resources to a task or service to match the demand for that task or service. Or an organisation structure that flexes in response to business changes.

Rolls-Royce RB3011. The Rolls-Royce RB3011 (previously designated RB2011) is a prototype propfan engine from Rolls-Royce plc. The design is also known as an "open rotor" engine.

Design and development

The RB3011 is designed for the 180–300 passenger aircraft (e.g. Boeing 737 or Airbus A320). The RB3011 was renamed from RB2011, because Rolls-Royce employees kept confusing the 2011 with the expected service entry date. Rolls-Royce bought the Allison Engine Company in 1995, and has studied the Pratt & Whitney/Allison 578-DX propfan engine built in the 1980s.

The engine has two contra-rotating rotors (fans) on the outside of the engine nacelle, either at the front of the assembly ("tractor") or at the rear ("pusher"). Both pusher and tractor open rotor designs form part of Rolls-Royce's long-term "15-50" vision, which is examining various architectures to tackle the 150 seat-aircraft market. Within 15-50 group – named for specific fuel consumption reductions of 15–50% compared with current generation engines – there are various options based on technology availability and maturity.

The open rotor design is known to have increased noise compared to normal turbofan engines, where noise is contained by the engine duct. The forward rotor is larger in diameter than the rear rotor, to avoid problems with eddies from the forward rotor tips. The rotors are powered by the engine shaft via an epicyclic gearbox. The rotors produce a large amount of heat.

In late 2008, the RB3011 was considered a contender for the powerplant of the Irkut MS-21. Rolls-Royce felt it could develop and certify the engine before the aircraft's planned (at the time) certification in the first quarter of 2015.

The engine has been tested at the Aircraft Research Association in Bedford, Bedfordshire. Wind-tunnel testing has taken place at DNW in Marknesse in the Netherlands.

It was hoped to reduce the fuel consumption of an aircraft, compared to those with normal turbofan engines, by up to 30%. This was the main reason for choosing this design of engine. Certification was planned for 2017–2018, with market entry with airlines planned by 2020.

Blackburn Sprat. The Blackburn T.R.1 Sprat was a British single-engine two-seat biplane trainer, built in 1926 for advanced training, deck-landing and seaplane experience. Just one was built.

Development
The Sprat was designed to Air Ministry Specification 5/24 as an RAF advanced trainer and Fleet Air Arm deck-landing trainer. It was specified that the aircraft should be readily convertible to a seaplane, again to be used as a trainer. The specification produced contracts for three machines, the Vickers Vendace, the Parnall Perch and the Sprat.

The Sprat, though a smaller aircraft, had strong family resemblances to the earlier Velos torpedo bomber. The Sprat was a staggered, single-bay biplane with equal-span wings that could be folded for carrier stowage. The fuselage centre section was built around a tubular-steel structure which linked the engine mounting and the wooded-framed rear fuselage. The two dual-control open cockpits were both behind the trailing edge of the wing for optimum visibility. Unusually, the instruments were placed on the rear spar of the upper wing centre section, where they could be read from both cockpits. The rudder area was large compared to that of the fin, and a braced tailplane was placed on top of the rear fuselage.

The main undercarriage was a robust split-axle construction, with the legs joining the wings at the bottom of the X-form centre-section struts. Braced stub axles carried the arrester claws required by the longitudinal arrester wires of Royal Navy aircraft carriers up to 1926. The undercarriage assembly was designed so that it could be easily removed with the aircraft on trestles, and replaced with a pair of aluminium single-step, V-bottomed round-topped floats. These carried water rudders for manoeuvring afloat.

The Sprat was powered by a water-cooled 275 hp (210 kW) Rolls-Royce Falcon III engine with a nose radiator, driving a four-bladed wooden propeller. As on the Velos, the upper engine cowling dropped smoothly away from the upper wing leading edge.

Operational history
The Sprat first flew at Blackburn's works at Brough Aerodrome, then went to Martlesham Heath for comparative trials with the other two contenders. In the end, though the Vendace was selected as the best aircraft for the specification, no orders were placed with any manufacturer because of economy cuts. The Sprat last appeared in public at the Hendon RAF display in July 1926.

Lowell Ordnance Plant. The Lowell Ordnance Plant was a small arms plant located on the border of Lowell, Billerica, and Tewksbury, Massachusetts that operated under contract from the Remington Arms Company between 1942 and 1943. It mostly produced .50 caliber machine gun ammo. A small run of .30 caliber machine gun ammo was also manufactured for less than a year.

The site has been identified as contaminated and has been undergoing remediation since the mid-1980s. It is currently being used as an industrial park.

The largest building in the industrial park was demolished during Summer 2020, to facilitate construction of a proposed Home Depot e-commerce warehouse.

GIO (software). GIO (Gnome Input/Output) is a library, designed to present programmers with a modern and usable interface to a virtual file system. It allows applications to access local and remote files with a single consistent API, which was designed "to overcome the shortcomings of GnomeVFS" and be "so good that developers prefer it over raw POSIX calls."

GIO serves as low-level system library for the GNOME Shell/GNOME/GTK software stack and is being developed by The GNOME Project. It is maintained as a separate library, , but it is bundled with GLib. GIO is free and open-source software released under the GNU Lesser General Public License.

Features
 The abstract file system model of GIO consists of a number of interfaces and base classes for I/O and files.
 There are a number of stream classes, similar to the input and output stream hierarchies that can be found in frameworks like Java.
 There are interfaces related to applications and the types of files they handle.
 There is a framework for storing and retrieving application settings.
 file type detection with xdgmime (xdg = X Desktop Group = freedesktop.org)
 file monitoring with inotify
 file monitoring with FAM
 There is support for network programming, including name resolution, lowlevel socket APIs and highlevel client and server helper classes.
 There is support for connecting to D-Bus, sending and receiving messages, owning and watching bus names, and making objects available on the bus.

Beyond these, GIO provides facilities for file monitoring, asynchronous I/O and filename completion. In addition to the interfaces, GIO provides implementations for the local case. Implementations for various network file systems are provided by the GVfs package as loadable modules.

Tugan Gannet. The Tugan LJW7 Gannet, also known later as the Wackett Gannet after its designer Lawrence Wackett, was a small twin-engined airliner built by Tugan Aircraft in Australia in the 1930s.  It was the first Australian-designed aircraft to enter series production. It was also the first Australian-designed and built aircraft to be taken on strength (put into operational service) by the Royal Australian Air Force.

Design and development
The Gannet was a strut-braced, high-wing monoplane of conventional design, with twin engines mounted in nacelles on the wings. The undercarriage was of fixed, tailwheel configuration with divided main units. The wings were of wooden construction, skinned in plywood, and the fuselage was built from welded steel covered in fabric. The prototype Gannet underwent flight testing in October 1935, and was destroyed in a crash shortly thereafter. The pilot and passengers perished in the ensuing fire, but despite this, the Gannet entered series production.

The type was operated by Butler Air Transport between Sydney and Broken Hill and at least one flew with Ansett Airways in 1943. RAAF Gannets saw service as survey aircraft between 1935 and 1942 when they were converted into air ambulances for the newly-formed No.2 Air Ambulance Unit. The last RAAF Gannets were scrapped in 1946.

Helical resonator. A helical resonator is a passive electrical component that can be used as a filter resonator.

Physically, a helical resonator is a wire helix surrounded by a square or cylindrical conductive shield.  One end of the helix is connected to the shield and the other end is left open (Weston, 2001, p. 660).  The device works like a coaxial resonator, but it is much shorter because the helical inner conductor reduces the velocity of wave propagation (Lancaster, 2006, p. 99).

Like cavity resonators, helical resonators can achieve Q factors in the 1000s. This is because at high frequencies, the skin effect results in most of the current flowing on the surface of the helix and shield. Plating the shield walls and helix with high conductivity materials increases the Q beyond that of bare copper (Blattenberger, 1989).

The length of wire is one quarter of the wavelength of interest. The helix is space wound, the gap between turns is equal to the diameter of the wire (Blattenberger, 1989).  If the open end of the helix is close to the end cap of the metal shield the length is somewhat reduced due to the capacitance between the conductor and the shield (Whittaker, 2000, p. 227).

Coupling to the resonator can be achieved with a tap wire soldered to the helix at some distance from the shorted end.  Input impedance varies with distance from the shorted end by impedance transformer action.  The tap point is chosen to achieve an impedance match with the connected circuit.  Tuning of the resonator may be achieved by inserting a screw into the central axis of the helix (Weston, 2001, p. 660).  Other means of input and output coupling used are a wire loop coupling to the magnetic field near the shorted end, or a probe capacitively coupling near the open end.  Coupling between resonators in a multi-resonator filter is often simply achieved with apertures in the shielding between them (Whittaker, 2000, p. 227).

Helical resonators are well suited to UHF frequencies ranging from 600 MHz to 1500 MHz (Blattenberger, 1989).
