Orleans (software framework). Orleans is a cross-platform software framework for building scalable and robust distributed interactive applications based on the .NET Framework or on the more recent .NET.

Overview
Orleans was originally created by the eXtreme Computing Group at Microsoft Research and introduced the virtual actor model as a new approach to building distributed systems for the cloud. Orleans scales from a single on-premises server to highly-available and globally distributed applications in the cloud.

The virtual actor model is based on the actor model but has several differences:

 A virtual actor always exists, it cannot be explicitly created or destroyed.
 Virtual actors are automatically instantiated. If a server hosting an actor crashes, the next message sent to the actor causes it to be reinstantiated automatically.
 The server that an actor is on is transparent to the application code.
 Orleans can automatically create multiple instances of the same stateless actor.

Starting with cloud services for the Halo franchise, the framework has been used by a number of cloud services at Microsoft and other companies since 2011. The core Orleans technology was transferred to 343 Industries and is available as open source since January 2015. The source code is licensed under MIT License and hosted on GitHub.

Orleans runs on Microsoft Windows, Linux, and macOS and is compatible with .NET Standard 2.0 and above.

Features
Some Orleans features include:
 Persistence
 Distributed ACID transactions
 Streams
 Timers & Reminders
 Fault tolerance

Related implementations
The Electronic Arts BioWare division created Project Orbit. It is a Java implementation of virtual actors that was heavily inspired by the Orleans project.

Parmentier Wee Mite. The Parmentier Wee Mite (sometimes Noel Wee Mite) was a British two-seat, parasol monoplane designed by Cecil Noel and first flown in Guernsey in 1933.

Design and development
The Wee Mite was a parasol monoplane with a welded steel frame with wooden wings and a fixed landing gear with a tailwheel. Designed by Cecil Noel and built by him and Harold James Le Parmentier it was initial powered by a  ABC Scorpion and first flown at Vazon Bay, Guernsey on 10 April 1933. The test flights or hops were not promising and after a forced landing and a damaged fuselage, the aircraft was rebuilt with a  British Salmson AD.9 engine and a lengthened fuselage by . It was successfully flown around Guernsey in a 50 minute flight on 15 September 1933.

It was registered as G-ACRL to Parmentier on 21 April 1934. It was dismantled and stored in 1936.

Sachdev–Ye–Kitaev model. In condensed matter physics and black hole physics, the Sachdev–Ye–Kitaev (SYK) model is an exactly solvable model initially proposed by Subir Sachdev and Jinwu Ye, and later modified by Alexei Kitaev to the present commonly used form. The model is believed to bring insights into the understanding of strongly correlated materials and it also has a close relation with the discrete model of AdS/CFT. Many condensed matter systems, such as quantum dot coupled to topological superconducting wires, graphene flake with irregular boundary, and kagome optical lattice with impurities, are proposed to be modeled by it. Some variants of the model are amenable to digital quantum simulation, with pioneering experiments implemented in nuclear magnetic resonance.

Model 
Let  be an integer and  an even integer such that , and consider a set of Majorana fermions  which are fermion operators satisfying conditions:
 Hermitian ;
 Clifford relation .

Let  be random variables whose expectations satisfy:

;
.

Then the SYK model is defined as

.

Note that sometimes an extra normalization factor is included.

The most famous model is when :

,

where the factor  is included to coincide with the most popular form.

Dyson School of Design Engineering. The Dyson School of Design Engineering is the academic centre for design engineering at Imperial College London. The school has just over 50 academic staff and 400 students, with over 220 undergraduates. The school is located in the Dyson building, at the corner of Exhibition and Imperial College roads.

History 
The school was founded in 2014 following a £12m donation by the James Dyson Foundation to the college, being the first new engineering division at Imperial for two decades. In 2018, the school moved into the newly-christened Dyson Building on Exhibition Road. The building was once the London headquarters of the Met Office, from 1910 to 1919, with some of the original interiors and signage preserved inside the entrance from Exhibition Road. Since then it has had various other uses, including as part of the Science Museum, which adjoins the building to the south, and as a post office. The renovation of the building was undertaken by Pascall+Watson, and cost £14 million.

Academics

Study 

The school offers a four-year integrated undergraduate Master of Engineering course, which started in 2015. The department offers five postgraduate courses, including a joint two-year postgraduate course with the Royal College of Art, Innovation Design Engineering, which awards a master's degree in each of art and science from the respective institutions. In addition, the department also offers four new specialised postgraduate courses including Cleantech Innovation (MSc), a joint course with Grantham Institute – Climate Change and the Environment, Design Engineering (MSc),  Design with Behaviour Science (MSc), and Design Engineering Research (MRes). As part of the Faculty of Engineering, undergraduates from the school are also awarded Associate of the City and Guilds of London Institute alongside their degree, and postgraduates are awarded the Diploma of Imperial College.

Panafacom. Panafacom was a Japanese microprocessor design firm established on 2 July 1973 by a consortium of companies that included Fujitsu, Fuji Electric and Matsushita (Panasonic). The company was formed to design and manufacture the MN1610, a 16-bit microprocessor. The MN1610 was released in April 1975, becoming one of the world's first single-chip 16-bit microprocessors.

The design saw relatively little use and remains largely unknown in the computer field. In 1987, Panafacom was merged with USAC Electronic Industrial to form today's PFU Limited.

Hans Hautsch. Hans Hautsch (January 4, 1595January 31, 1670) was a German toolmaker and inventor from Ledergasse, Nuremberg. His father, Antoni (15631627), and grandfather, Kilian (died 1570), were both toolmakers.

He married Magdalena (born 1603), the daughter of carpenter Jacob Flexlein, on June 25, 1621. They had a daughter and five sons, including Georg (born 1624, also a toolmaker), Gottfried (16341703), and Johann Andreas (born 1638). Gottfried Hautsch invented the conical touch hole for muzzle-loading guns, whereby the pan closed itself, cutting loading time by two thirds.

Inventions 
In 1649, Hans Hautsch designed a wheelchair for gout patients.

Shortly thereafter, he built a self-propelled, four-wheeled mechanical carriage: "It moves by itself and requires no initial preload, from a horse or anything else. The car travels 2000 paces every hour; it stops when the driver pleases, starts when the driver pleases, and works entirely on clockwork."

Shortly afterwards, he was commissioned to produce another chariot, which also apparently operated on clockwork. However, contemporaries were skeptical. In his Mathematischen Erquickstunden (or A Refresher Course in Mathematics, 1651), Georg Philipp Harsdörffer suggested there was a child inside working a crank. French travel writer Balthasar de Monconys, in his 1666 Journal des Voyages, was similarly unconvinced. 

In 1650, Hautsch built a fire engine that used a pressurized air vessel to issue a continuous stream of water up to 20m high. On each side, 14 men worked a piston rod back and forth horizontally; a rotating pipe mounted on the hose allowed for a continuous stream of water, even when the piston was being pulled backwards. Caspar Schott observed the engine in 1655 and wrote an account of it in his Magia Universalis.

Around 1660, for the occasion of an imperial visit to Nuremberg, Hautsch built a motorized eagle that flapped its wings. This appears to have caused a rumour that he had invented a flying machine.

For the king of Denmark, in 1664, he produced a mechanised dollhouse whose figures performed over 100 individual movements. The following year, he made an instructional model battle for the son of King Louis XIV of France with 462 moving silver soldiers and combat sound effects. He also built a three-storey exhibition which depicted Creation and other Biblical scenes on the bottom stage, seventy-two craftsmen working in the middle, and a large bath house on top. 

Hautsch also invented Streuglanz, a sparkling, multicolored gloss made from metal shavings. His descendants continued to prepare Streuglanz for small-scale production of wallpaper and enamelled crafts until the end of the eighteenth century.

Nanoconcrete. Nanoconcrete (also spelled nano concrete or nano-concrete) is a form of concrete that contains Portland cement particles that are no greater than 100 μm and particles of silica no greater than 500 μm,  which fill voids that would otherwise occur in normal concrete, thereby substantially increasing the material's strength. It is also a product of high-energy mixing (HEM) of conventional cement, sand and water which is a bottom-up approach of nano technology.

Role of nano particles 
The incorporation of ultra-fine particles into a Portland-cement paste within a concrete mixture in accordance with top-down approach of nano technology alters the concrete's material properties and performance by reducing the  void space between the cement and aggregate in the cured concrete. This improves strength, durability, shrinkage and bonding to steel reinforcing bars.

Manufacture 
To ensure the mixing is thorough enough to create nanoconcrete, the mixer must apply a total mixing power to the mixture of 30–600 watts per kilogram of the mix. This mixing must continue long enough to yield a net specific energy expended upon the mix of at least 5000 joules per kilogram of the mix. and may be increased to 30–80 kJ per kilogram. A superplasticizer is then added to the activated mixture which can later be mixed with aggregates in a conventional concrete mixer. In the HEM process, the intense mixing of cement and water with or without sand in conditions of queasy laminar flow, Reynolds number 20-800 provides dissipation and absorption of energy by the mixture and increases shear stresses on the surface of cement particles. As a result, the temperature of the mixture increases by 20–25 and more degrees Celsius. This intense mixing serves to deepen hydration process inside the cement particles. The nano-sized colloid Calcium Silicate Hydrate (C-S-H) formation increased several times compared with conventional mixing. Thus, the ordinary concrete transforms to nanoconcrete.
The initial natural process of cement hydration with formation of colloidal globules about 5 nm in diameter spreads into the entire volume of cement–water matrix as the energy expended upon the mix.
The liquid activated mixture can be used by itself for casting small architectural details and decorative items, or expanded with gas-forming admixture for making Aerated HEM Nanoconcrete  as a lightweight concrete. HEM Nanoconcrete hardens in low and subzero temperature conditions because the liquid phase inside the nano-pores of C-S-H gel doesn't freeze at temperatures from −8 to −42 degrees Celsius. The increased volume of gel reduces capillarity in solid and porous materials.

Richard Leonard Howard-Flanders. Richard Leonard Howard-Flanders  (1882 – 1939) was an early British aircraft designer and manufacturer.

Early life
Richard Leonard Flanders (later Howard-Flanders) was born in Italy to British parents in 1882. He was educated at Emmanuel College, Cambridge and then served an engineering apprenticeship at Brazil Straker and Company of Bristol. In 1909 he joined A.V. Roe before forming his own company (L. Howard Flanders Limited) at Brooklands Aerodrome in 1910.

Aircraft designer

He designed a built a series of monoplanes including the Flanders F.4 that was entered in the Military Trials of 1912. It was damaged and unable to compete in the trials. A small number of his aircraft were built for the British Army. Howard-Flanders had a serious motorcycle accident and during his convalescence his company had to close down. He joined the aircraft department of Vickers Limited and later in 1917 moved to the engine section. After he left Vickers he worked for a number of companies including English Electric and the Bristol Aeroplane Company. In 1921 he was registered with the Teachers Registration Council when he was Assistant Master at the Regent Street Polytechnic from 1920 to 1923 In the 1930s he was secretary of the British Gliding Association.

HuskySat-1. HuskySat-1 is an artificial satellite designed at the University of Washington. It was launched by Cygnus NG-12 from Mid-Atlantic Regional Spaceport Launch Pad 0 on Wallops Island, Virginia to low earth orbit on November 2, 2019. It is a CubeSat, and will demonstrate onboard plasma propulsion and high gain telemetry for low Earth orbit that would be a precursor for an attempt at a larger CubeSat designed for orbital insertion at the Moon. 

The satellite was designed by Husky Satellite Lab, a registered student group, in Johnson Hall, and was controlled from there using three antennae installed on the roof.

A pulsed plasma thruster (PPT) provides propulsion. It is the first PPT to use sulfur as a fuel.

Students at Raisbeck Aviation High School designed an onboard camera.

The satellite will test an experimental 24 GHz data transmitter, after which it will become an amateur radio satellite operated by AMSAT. The high data rate will enable much more data to be transferred during the 9- to 15-minute time windows the satellite is visible from the control station.

HuskySat is the first satellite designed by students in Washington state.

The satellite decayed from orbit on 12 April 2023.
