The Diamond, Sheffield. The Diamond is a building in Sheffield, South Yorkshire, part of the University of Sheffield. Housing specialist engineering facilities as well as seminar room and open plan study spaces, it was completed in September 2015 at a cost of £81 million, the largest capital investment ever made by the university. It is situated on Leavygreave Road, between the Jessop Wing and St George's Church.

History 

The Diamond was built to replace the Grade II-listed Edwardian wing of the Jessop Hospital, taking over from the Sir Frederick Mappin Building as the new home of the Faculty of Engineering, the largest faculty at the university, with the goal to double student numbers in the faculty by 2021. Construction work began in July 2013 and the building opened in September 2015, in time for the start of that year's autumn semester.

Building 
The building takes its name from its unique facade, which comprises a cellular pattern of interconnected diamond shapes made of anodised aluminium, inspired by the form of diamond at a molecular level, over a frame of reinforced concrete and exterior glass cladding. It has nine lecture theatres, nineteen laboratories and more than thirty classrooms, linked by a central atrium area with a large study space and a café. Within the atrium, curved pods house IT suites and small seminar rooms.

Reaction 
Reaction to the building was mixed. It received a commendation from the British Constructional Steelwork Association Structural Steel Design Awards for its design and construction, and MP for Sheffield Central Paul Blomfield commented that the building would be "the jewel in the crown not only for the University itself, but also for the city". It was shortlisted for the 2016 Carbuncle Cup, awarded to the ugliest new building in the UK. The architectural magazine Building Design described it thus: "with the efficiency of a twin-thrust turbo engine, it commits sins on both the outside and the inside."

Vanadium(V) chloride chlorimide. Vanadium (V) chloride chlorimide is a chemical compound containing vanadium in a +5 oxidation state bound to three chlorine atoms and with a double bond to a chlorimide group (=NCl). It has formula VNCl4. This can be also considered as a chloroiminato complex.

Production
Vanadium(V) chloride chlorimide can be made by chlorinating vanadium nitride at 120°. Or chlorine azide can react with vanadium tetrachloride to yield it. Or more conveniently it can be made by heating vanadium tetrachloride with sodium azide and chlorine gas.

Properties
The melting point of Vanadium(V) chloride chlorimide is 136 °C. It can be sublimed in a vacuum below its melting point. The density of the solid is 2.48. The solid has a triclinic crystal structure with unit cell a=7.64, b=7.14, c=5.91 Å; α=112.4°, β=94.9°, γ=107.8° with Z=2 (formulas per unit cell). The space group is P.

Vanadium(V) chloride chlorimide is molecular. In the gas phase the V to N bond length is 1.651 Å, V to Cl bond length is 2.138 Å, N to Cl bond length is 1.597 Å. The bond angles are ∠ClVCl 113.4°, VNCl 169.7 and ∠NVCl 106.0.

In the solid form, the bond lengths are slightly different. V-Cl: 2.20, 2.30 and 2.38 Å, V=N bond is 1.64 Å long and N-Cl length is 1.59 Å. The VNC angle is 175.2°.

Reactions
VCl3NCl can crystallise with antimony pentachloride. Phosphines and nitrogen bases can form complexes with the vanadium in this compound. (triphenyl phosphine, tributyl phosphine, pyridine, bipyridine). A reaction with ammonium chloride yields the [Cl5VNCl]2− ion.

Nickel monosilicide. Nickel monosilicide is an intermetallic compound formed out of nickel and silicon. Like other nickel silicides, NiSi is of importance in the area of microelectronics.

Preparation 
Nickel monosilicide can be prepared by depositing a nickel layer on silicon and subsequent annealing. In the case of Ni films with thicknesses above 4 nm, the normal phase transition is given by Ni2Si at 250 °C followed by NiSi at 350 °C and NiSi2 at approximately 800 °C. For films with an initial Ni thickness below 4 nm a direct transition from orthorhombic Ni2Si to epitaxial NiSi2−x, skipping the nickel monosilicide phase, is observed.

Uses 
Several properties make NiSi an important local contact material in the area of microelectronics, among them a reduced thermal budget, low resistivity of 13–14 μΩ·cm and a reduced Si consumption when compared to alternative compounds.

EA203 series. The EA203 series is an Electric Multiple Unit produced by Industri Kereta Api, in collaboration with Bombardier which will be used as Soekarno–Hatta Airport Rail Link express services from Manggarai Station in Jakarta to Soekarno–Hatta International Airport at Tangerang, Banten. EA203 series was purchased by PT Railink, a joint venture between PT Kereta Api Indonesia and PT Angkasa Pura II which is the operator of the airport train in Indonesia, totaling 60 units divided into 10 series with 6 car formations. EA203 series was sent from its factory in Madiun to Jakarta in stages starting in August 2017.

Design and technology

Design 
EA203 series has an aerodynamic exterior design with a shape like express trains in general. EA203 series is colored white with orange and blue stripes, which match the corporate identity of Railink and Kereta Api Indonesia (KAI). Around the passenger window, it is given a black color like the latest KAI executive trains which gives it the impression of elegant luxury. On cabins, there are three matrix objective display units light emitting diode which display the route of the train's journey, while on the middle train there are two display units for destination.

The interior is predominantly white in color, with passenger seats made of synthetic leather colored gray and blackish gray. The passenger seats on this EMU cannot be rotated, and have a configuration like the latest Indonesian railway economy trains, where seats number 1-5 face the direction of the train's journey downstream while numbers 6-10 face the opposite direction. There are also special seats for persons with disabilities that are sideways to the direction of the train, such as on KRL Commuterline, but with the same seat material as the other seats. In each train there is a luggage rack and a toilet with sitting toilets and a fireplace. In addition, there are also four television screens at each end of the row of chairs, which are used to show entertainment to EMU Railink users.

Technology 
EA203 series uses the IGBT-VVVF traction system under the name MITRAC produced by Bombardier Transportation which is one of the most advanced traction propulsion systems ever produced by Bombardier at this time. EA203 series uses Train Information Monitoring System (TIMS) which is also used on other INKA-made AC EMUs. EA203 series uses air-spring bogie (bolsterless) with the TB-914 type on the train driver's cabin and the MB-514 on the middle train, which is a development of the EA201 series and Inka-Hitachi EMU, which also has a similar shape to the TR235D/TR241B/TR246E and DT50D bogie on the 203 series and 205 series which is a EMUs produced by a Japanese manufacturer. This type of bogie is known as a bogie with minimal shock. In addition, EA203 series is also more soundproof than other INKA EMU production. This is due to the use of accordion-type connection covers which are also used on the ex-Japanese EMU belonging to Kereta Commuter Indonesia.

NEVS 9-3 EV. The NEVS 9-3EV is an electric compact executive car produced by NEVS from December 2017 to 2022.

History
The 9-3EV is a slightly modernized Saab 9-3 of the second generation after a design facelift. It was built on the same platform - GM Epsilon I platform, which was used to build, among others the Chevrolet Malibu and the Opel Vectra.

Compared to the Saab 9-3 model produced in 2013 by NEVS, the car is distinguished by a slightly higher bonnet to comply with current pedestrian safety regulations, a slightly remodeled radiator grille, as well as fog lights and additional direction indicators located in the exterior mirrors.

The electric motor is responsible for the drive of the vehicle. Its range is on average  on a single charge.

NEVS presented the 9-3 sedan and the 9-3X station wagon at CES Asia held in June 2017 in Shanghai. Pre-series production started after a launching ceremony was held on 5 December 2017 in Tianjin. The first delivery to a customer took place on 29 December 2018. Series production started on 29 June 2019 in Tianjin.

Production of the 9-3EV came to an end in 2022 just before NEVS reduced its workforce to a minimum in March 2023 and froze operations.

Indonesian Aerospace Elang Hitam. The Elang Hitam () is an unmanned aerial vehicle (UAV) being developed by PT Dirgantara Indonesia (IAe) in cooperation with a consortium of five other institutions. This drone was first shown on December 30, 2019 at the PTDI hangar, Bandung, West Java.

The EH is the result of collaboration in the formation of a consortium between the Agency for the Assessment and Application of Technology (BPPT), Ministry of Defense, Indonesian Air Force, ITB, PT Dirgantara Indonesia, and PT LEN Persero.

Development history 
According to PT DI and BPPT, the development of a MALE UCAV has been initiated by the Ministry of Defense's R&D since 2015 involving the TNI, Ditjen Pothan Kemhan, Ministry of Defense, BPPT, ITB, and PT Dirgantara Indonesia (Persero). This was marked by creating a design agreement, drafting the requirements and objectives (DR&O) and determining the user, in this case it would be the TNI, especially the TNI-AU. During development, the UAV was formerly  known as (). Plans were made to introduce it as a UAV in 2022 before it would be further developed as a UCAV in 2024.

The development started with preliminary design, basic design by making two wind tunnel models and the conclusion of test results in 2016 and 2018. In 2019, LAPAN entered as a member of the consortium, and took part in the development of the MALE UCAV.

The first prototype was rolled out on 30 December 2019 in the PTDI hangar. First flight is expected to take place at the end of 2020. The Elang Hitam, according to its development plan, will be armed with missiles and capable of flying up to 30 hours non-stop with a cruising altitude of up to 23,000 ft. The specification is said to match the Chinese-made CH-4 Rainbow drone.

Due to the Covid-19 pandemic, the first flight which was originally scheduled to fly for the first time in 2020 has been postponed to late 2021.

On 1 June 2022, PT LEN Industry contract to develop Elang Hitam mission system is renewed by Indonesian Defense Ministry.

On July 17, 2022, Indonesia announced a collaboration with Turkey to manufacture air-to-surface missiles that can be easily mounted on UAVs. However, further development on the EH was suspended as of September 15, 2022.

Edda Sveinsdottir. Edda Sveinsdottir (1936 – 3 April 2022) was an Icelandic/Danish computer scientist, inventor, and professor. She is considered to be the first female Danish computer scientist and was the first (and currently only) female head of department at University of Copenhagen's Department of Computer Science.

Early life 
Sveinsdottir was born in 1936 in Reykjavik to Icelandic father, Professor Sveinn Bergsveinsson, and Danish mother, architect Anne Marie Østergaard. Sveinsdottir's parents divorced when she was three years old, and she lived with her mother, grandmother, and three aunts in Denmark, continuing to live much of her life in Denmark.

Sveinsdottir studied at Ordrup Gymnasium, where she met Niels Alexander Lassen. After graduating in 1955, they married the same year and began professional collaboration. After having four sons together, they later divorced, whilst still continuing their professional relationship.

Career 
Sveinsdottir began studying mathematics and physics, with numerical analysis as her major, at Copenhagen University in 1958. In 1965 she obtained her master's degree in Mathematics. From 1965 to 1970 she was employed at the Department of Mathematics at Copenhagen University where she worked on the electronic calculator, GIER – Denmark's second ever computer. It was during this time Sveinsdottir was drawn to the newly forming computer environment in Denmark and learned programming at the Technical University of Denmark. When the Department of Computer Science at Copenhagen University was established in 1970, she was appointed as an associate professor and, later, head of department (during 1970-1971 and 1982-1984), making her one of the subject's early pioneers.

Sveinsdottir's field of research has focussed on computer-assisted tomography, a branch of medical technology which uses computers to develop equipment for the imaging of brain activity. She pioneered the use of computers for imaging, rather that for numbers as they had previously been used.

In the mid-1970s, she co-founded the electronics company Medimatic A / S which launched a new type of computer software.

In 1987, Sveinsdottir was made a professor of computer science at Roskilde University Center (RUC). In 1976-78 she was appointed chairperson of the National Academic Committee for the Natural Sciences.

Wallenius Marine. Wallenius Marine is a ship design and ship management company in Sweden. Headquartered in Stockholm, the company has additional offices in Singapore and employs some 800 people.

The company was spun off from Wallenius Lines in 2003 to focus on ship management and technical services, as well as newbuilding and design. Like its sister company, Wallenius Marine specializes in car carriers and RoRo ships. Since the 1990s, the company and its predecessor has designed and built 70 vessels. The ships are built in third-party shipyards in Japan, South Korea and China with site supervision by Wallenius Marine.

Other business areas include ship elongation, where existing cargo vessels are stretched to extend their capacity. During the process, ships are cut in half, extended and put back together. The process typically takes a few months compared to a few years for designing and building a new ship from scratch. Wallenius Marine also provides marine IT and ship management, including monitoring, communication and fleet management systems.

In recent years, the company's focus has increasingly shifted towards sustainable shipping. In addition to reducing the environmental impact of traditional cargo ships, the company is developing a wind-powered car carrier called Oceanbird. The vessel is powered by large, wing-like sails and would become the tallest sailing ship in the world. It is designed to carry 7,000 cars.

Hiro H3H1. The Hiro H3H1 or Navy Type 90-1 Flying boat was a Japanese flying boat bomber built in 1931. It was the first large all-metal aircraft built in Japan. Only one was completed.

Design and development
The H3H1 was Hiro Naval Arsenal's first large all-metal, stressed-skin aircraft, though they had long experience of large, wooden, flying boat design and construction. It was the first Japanese Naval aircraft able to carry a one tonne bomb load. Built in 1931, it was first flown in the spring of 1932.

It had a shoulder-mounted, cantilever wing built around a type of single box spar previously proven by the German company Rohrbach. Its three licence-built, , Hispano-Suiza V12 engines were tractor mounted over the wing on multi-strut pylons. Lateral stability on the water was provided by floats at mid-span, mounted on vertical N-struts and braced by inward parallel strut pairs to the wing.

The hull incorporated both Hiro's experience and some features from that of the Supermarine Southampton, with hydrodynamics refined in the water tank of the Naval Technical Research Institution. The H3H1 was flown from a side-by-side, open cockpit well ahead of the wings. There was an open mooring cockpit in the nose, also equipped with a pair of flexibly mounted  machine guns, and other, similarly equipped, gun positions amidships and in the tail. The maximum bomb load was . Its tail surfaces were conventional with the tailplane mounted just above the base of the fin and braced to the fuselage on N-struts.

After its first flight, the H3H1 flew to Yokohama for extensive testing which revealed problems with aerodynamic stability and with the engine installations. The former led to the addition of auxiliary fins on the tailplane and modification of the tailplane struts to allow its incidence to be adjusted for trimming. The engines had their radiators moved further aft, and different propellers were tested. The modification state was denoted with a dash number suffix, thus the final modification state of the Navy Type 90-1 Flying boat was the Navy Type 90-1-4 Flying boat.

Despite the changes, the stability problems persisted and the contemporary, but more traditional, Kawanishi H3K biplane was preferred by the Navy. From 1933, the H3H1 was used as an engine test-bed for the Mitsubishi MK1 Shinten  14 cylinder, double-row  radial engine.
