SampTA. SampTA (Sampling Theory and Applications) is a biennial interdisciplinary conference for mathematicians, engineers, and applied scientists. The main purpose of SampTA is to exchange recent advances in sampling theory and to explore new trends and directions in the related areas of application. The conference focuses on such fields as signal processing and image processing, coding theory, control theory, real analysis and complex analysis, harmonic analysis, and the theory of differential equations. All of these topics have received a large degree of attention from machine learning researchers, with SampTA serving as bridge between these two communities.

SampTA features plenary talks by prominent speakers, special sessions on selected topics reflecting the current trends in sampling theory and its applications to the engineering sciences, as well as regular sessions about traditional topics in sampling theory. Contributions from authors attending the SampTA conferences are usually published in special issues of Sampling Theory in Signal and Image Processing, an international journal dedicated to sampling theory and its applications. The proceedings of SampTA 2015 were indexed in IEEE Xplore.

The SampTA conference series began as a small workshop in 1995 in Riga, Latvia, but the meetings grew into full-fledged conferences attracting an even mix of mathematicians and engineers as the interest in sampling theory and its many applications blossomed. This even mix makes the SampTA meetings unique in the scientific community. The conference organization is headed by an international steering committee consisting of prominent mathematicians and engineers, and a technical committee responsible for the conference program. Due to the COVID-19 pandemic, SampTA paused from 2020–2022, but resumed in Summer 2023.

The biennial meetings are announced in various Mathematics and Engineering Calendars, including the Mathematics Calendar of the American Mathematical Society, the Wavelet Digest., 
the Numerical Harmonic Analysis Group (NuHAG) at the University of Vienna, the Norbert Wiener Center at the University of Maryland, and the IEEE Signal Processing Society.

Requirements Engineering Specialist Group. The Requirements Engineering Specialist Group (RESG) is a Specialist Group of the British Computer Society. It runs events on all aspects of Requirements.

Mission of the RESG 

The RESG's stated purpose is "to provide a forum for interaction between the many disciplines involved" in Requirements Engineering, which it explains is "a key activity in the development of software systems and is concerned with the identification of the goals of stakeholders and their elaboration into precise statements of desired services and behaviour." The RESG describes Requirements engineering as "the elicitation, definition, modelling, analysis, specification and validation of what is needed from a system.". The RESG's stated mission is to attempt to bridge the gap between industry and research, as it "welcomes members from, and organises events for practitioners, academics and students" in the field.

History of the RESG 

The RESG was founded in 1994 by Bashar Nuseibeh of Imperial College (now professor at the Open University), Neil Maiden of City University (also now professor), Paul Gough of Philips Labs, Sara Jones of the University of Hertfordshire, Steve Easterbrook of the University of Sussex, and Orlena Gotel of Imperial College. It has run events and published its newsletter ever since.

The RESG's first Chairman was Bashar Nuseibeh. He was succeeded by Pete Sawyer, Ian Alexander and Emmanuel Letier.

Events 

The RESG has run "workshops, seminars and tutorials on all aspects of requirements engineering", held "in a variety of locations in the UK, including London, Manchester, York and Edinburgh". In 1998, the RESG, with the RENOIR project, ran a 2-day Conference on European Industrial Requirements Engineering (CEIRE'98) in London. Events have included a 'Goals day'; workshops on 'Agile Requirements' and 'Self-Adaptive Systems'; an 'i* Showcase'; special events for post-doctoral researchers; Scenarios days; an event on software services; annual events on 'Careers in RE'; informal 'birds of a feather' pub meetings; book launches; and workshops at the annual international RE conference on 'RE Education and Training'

Newsletter 

The RESG published a newsletter since its foundation. The first 35 issues were titled "Requirenautics Quarterly", with Issue 1 published in October 1994. Since Issue 36, the newsletter has been titled "Requirements Quarterly". The founding editor was Steve Easterbrook, then at Sussex University, succeeded by Pete Sawyer of Lancaster University, Ian Alexander of Scenario Plus Ltd, Simon Hutton of Headmark Analysis, and William Heaven.

Patron 

The RESG's patron is Professor Michael A. Jackson, the creator of JSP and JSD, and the inventor of the Problem Frames approach to requirements.

Sion railway station (India). Sion is a railway station on the Central line of the Mumbai Suburban Railway network, located in the Mumbai neighborhood of Sion.

Its location near the Mithi River means that the railway between Sion and Kurla, directly to the north, has flooded frequently during the Indian monsoon. However, in 2019, the Central Railway conducted work to raise the trackbed by four to six inches to prevent future flooding. Previously, 30 mm of rain in 24 hours flooded the track, but now there will be no disruption of services with 100 mm of rain per day.

Despite this work, the tracks near this station still experienced water-logging and flooding during the 2019 floods in Mumbai.

History 
Sion can be considered the actual place of inauguration of the GIP Railway, since it was here that the "first sod for the railway was turned" by the Chief Secretary of the then Bombay Government, John P. Willoughby. Sion was one of the stations for the First Passenger Train of India (the second stop), that ran on 16 April 1853, where its engines were 'watered' and its wheels greased. 

The original Sion station was not situated at its present site, but was somewhere close to Kurla. While the name of the station was initially Sion, in 1855, it was therefore renamed to Kurla. (in 1895, this station was shifted to its present site, and is still called the Kurla Station) There was no railway station between this old station and Dadar, which proved to be of great inconvenience to the passengers. Therefore, in 1872, 107 local inhabitants from Sion and nearby villages sent a petition to the Railway Company (GIPR) to request a station be built. Considering the petitions and the benefits it offered, the GIPR eventually built an official station, the Sion Station. This new station was opened on 3 November 1873.

Oldroyd-B model. The Oldroyd-B model is a constitutive model used to describe the flow of viscoelastic fluids.
This model can be regarded as an extension of the upper-convected Maxwell model and is equivalent to a fluid filled with elastic bead and spring dumbbells.
The model is named after its creator James G. Oldroyd.

The model can be written as:

where:
  is the deviatoric part of the stress tensor;
  is the relaxation time;
  is the retardation time = ;
  is the upper-convected time derivative of stress tensor: 
 is the fluid velocity;
 is the total viscosity composed of solvent and polymer components, ;
 is the deformation rate tensor or rate of strain tensor, .

The model can also be written split into polymeric (viscoelastic) part separately from the solvent part:

where 

Whilst the model gives good approximations of viscoelastic fluids in shear flow, it has an unphysical singularity in extensional flow, where the dumbbells are infinitely stretched. This is, however, specific to idealised flow; in the case of a cross-slot geometry the extensional flow is not ideal, so the stress, although singular, remains integrable, i.e. the stress is infinite in a correspondingly infinitely small region.

If the solvent viscosity is zero, the Oldroyd-B becomes the upper-convected Maxwell model.

German submarine U-962. German submarine U-962 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine during World War II. Her keel was laid at the yards of Blohm & Voss in Hamburg on 7 April 1942. Launched on 17 December 1942, she was formally commissioned  on 11 February 1943 and given to Oberleutnant zur See Ernst Liesberg, who commanded the submarine on both of her active war patrols.

Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-962 had a displacement of  when at the surface and  while submerged. She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of  for use while surfaced, two Brown, Boveri & Cie GG UB 720/8 double-acting electric motors producing a total of  for use while submerged. She had two shafts and two  propellers. The boat was capable of operating at depths of up to .

The submarine had a maximum surface speed of  and a maximum submerged speed of . When submerged, the boat could operate for  at ; when surfaced, she could travel  at . U-962 was fitted with five  torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one  SK C/35 naval gun, 220 rounds, and one twin  C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.

Service history

War patrols
After her working up period ended, U-962 departed Kiel for Bergen, Norway on 23 September 1943, arriving on 27 September. After a stay of about a month, the crew cast off on their first active patrol 3 November 1943. This 56-day cruise in the mid-Atlantic Ocean yielded no targets and the patrol was terminated at St. Nazaire in occupied France on 28 December 1943.

On 14 February 1944, U-962 departed St. Nazaire on her second and last patrol. She again cruised in the central Atlantic for 55 days until she ran afoul of the British sloops  and  and sunk in position  by depth charges on 8 April 1944. There were no survivors.

Wolfpacks
U-962 took part in five wolfpacks, namely:
 Coronel (4 – 8 December 1943) 
 Coronel 2 (8 – 14 December 1943) 
 Coronel 3 (14 – 17 December 1943) 
 Borkum (18 – 26 December 1943) 
 Preussen (22 February – 22 March 1944)

Belite Aircraft Superlite. The Belite Superlite, originally the product of Belite Aircraft, is a single-seat, high-wing, single-engine ultralight aircraft developed from the Kitfox Lite aircraft especially for the United States FAR 103 Ultralight Vehicles category.

Design and development
Designer James Wiebe bought the assets and tooling of the Kitfox Lite from Skystar. He modified the prototype Kitfox Lite to meet FAR 103 regulations requiring an ultralight aircraft to have an empty weight of less than .

The fuselage is made from 4130 steel tubing. Flaperons and vortex generators are used to improve roll control and low speed flight. The wings are foldable for storage.

Items were substituted with carbon-fiber-reinforced polymer to make the aircraft lighter than a Kitfox Lite. This included the tailwheel leaf spring, wing spars, wing ribs (aluminum on later kits), lift struts, firewall, elevator and fuel tank. A variety of engines may be used such as the Hirth F33, Hirth F-23, Zanzottera MZ 34, 1/2 Volkswagen air-cooled engine and the Zanzottera MZ 201.

Popular culture
A Belite aircraft was used in the show Mythbusters Episode 174 – Duct Tape Plane.  A Belite was "mauled" by an artificial bear claw with the damage being limited to the fabric skin of the rear fuselage and vertical stabilizer. The control surfaces were not damaged during the destruction. The aircraft was then repaired with Duct-Tape and successfully flown.

Note: This is not to be confused with Speed tape.

Aerotique Parasol. The Aerotique Parasol is an American parasol-wing, strut-braced, conventional landing gear, single-seat, open cockpit, single engine in tractor configuration, ultralight aircraft that was designed as an ultralight version of the 1926 vintage Heath Parasol. It was originally produced by Yesteryear Aviation and later by Aerotique Aviation. The aircraft was supplied as factory-built only.

Design and development
The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of . The Parasol's factory standard empty weight was .

The aircraft's fuselage is built with an aluminium tube structure, with wooden wings, all covered with doped aircraft fabric covering. Early production models used wooden wing ribs, while later models transitioned to aluminium ribs. Its  span wing uses parallel lift struts supported by jury struts and flying wires. The wings are removable for transportation or storage and take about an hour to remove. The factory installed engine was the Rotax 277, single cylinder, two-stroke powerplant of . Other than the engine and the wheels, all parts are certified aircraft parts.

The Parasol has conventional three-axis controls, including half-span ailerons. The main landing gear is bungee-suspended and the tail has a steerable skid. Brakes were optional and taxiing the aircraft without them was described as "a little tricky".

As is the case with many parasol designs where the pilot sits directly underneath the wing on the aircraft's center of gravity, the cockpit access is restricted by the close proximity of the wing.

Amsterdam Type Foundry. The Amsterdam Type Foundry () was a type foundry based in Amsterdam, Netherlands.

History
The type foundry was established by Nicolaas Tetterode in 1851.

It contributed a number of original type designs early in the 20th century, some of which were designed by S. H. de Roos and Dick Dooijes.

In the 20th century, only two major typefoundries survived in the Netherlands. In Haarlem, the old typefoundry of Joh. Enschedé was their competitor. In order to divide the market, these firms kept a certain difference in type-height. Amsterdam: 66 + 1/24 point Didot, and Enschedé: 66 - 1/24 point Didot. Enough to prevent the combined use of their type.

Eventually, it became a division of Tetterode. On October 1, 2000, Tetterode transferred the rights for all of its typefaces to Linotype.

Radlock Trainer. The Radlock Trainer was a single seat primary glider designed and built by members of the Hull Experimental Gliding Club as a basic trainer for their own use in the early 1930s.  It was a simple, single exposed seat, wooden glider with a parasol wing.

Design and development
In 1931 two members of the Hedon-based Hull Experimental Gliding Club designed a single-seat primary glider, known as the Radlock glider from a conjunction of their names, Raddings and Locke. The designers worked for Blackburn Aeroplane and Motor Co., Ltd., based  at Brough near Hull. The club had a workshop at Hessle and the glider was built there by members during 1931–1932.

The Radlock glider had a wing of rectangular plan built around two spars. It carried ailerons but no  flaps or airbrakes.  The wing was attached high above the fuselage by a pair of lift struts, one from the upper fuselage to the forward spar and the other reaching forwards from the lower fuselage member, behind the wing trailing edge, to the aft spar.  Both lift struts joined the wing at about mid-span.  The centre section was braced with a single N-form set of struts and these also provided a base for a triangular kingpost above the wing, from which a pair of landing wires on each side ran to the spars at mid-span.

The fuselage was simple, very narrow and shallow, being formed from two members, one above the other and joined by short X-shaped webs. The pilot sat below the leading edge of the wing, his seat and controls on a short platform attached to the upper fuselage member. There was a short, square fin with the triangular tailplane on top of it.  The rudder was almost twice the height of the fin and reached down to the lower fuselage, moving in a cut-out between the elevators.  The rear of the fuselage was laterally braced by a pair of wires from the rear spar at the tops of the lift strut to the rear end of the lower fuselage member.

Originally the Radlock landed on the skid-shaped lower fuselage member, though later a simple pair of wheels was added for auto-towed launches. A photograph taken before September 1932 may show the wheels in place before the tail covering was complete.   There was a tail bumper.

Operational history

The first flight was made in 1932.  No BGA Certificate of Airworthiness number was recorded.  The Radlock seems to have been in regular use with the Hull G.C. at Hedon in 1933, with auto-launches for free flights and auto-towing for training.  It is not known how long it remained in service.
