Intelsat II F-1. Intelsat II F-1, also known as Blue Bird was a communications satellite operated by Intelsat. Launched in 1966 it was intended for operations in geostationary orbit over the Pacific Ocean to provide a communications link between Australia and the United States, however a malfunction prevented the satellite from reaching its planned orbit.

The first of four Intelsat II satellites to be launched, Intelsat II F-1 was built by Hughes Aircraft around the HS-303A satellite bus. It carried two transponders, which were powered by body-mounted solar cells generating 85 watts of power.

Intelsat II F-1 was launched atop a Delta E1 rocket flying from Launch Complex 17B at the Cape Canaveral Air Force Station. The launch, which was successful, took place at 23:05:00 UTC on October 26, 1966, with the spacecraft entering a geosynchronous transfer orbit as planned. The spacecraft was equipped with an SVM-1 apogee motor, which was to be fired to raise the spacecraft into its operational geostationary orbit, however this failed four seconds after ignition. The spacecraft was left in its transfer orbit, unable to complete its primary mission, however it was used for some tests and limited communications.

Intelsat II F-1 remains in orbit. As of 2 May 2023 it was in an orbit with a perigee of , an apogee of , inclination of 17.70 degrees and an orbital period of 11.97 hours.

A Vlaicu I. The A Vlaicu I was the first powered airplane built by Aurel Vlaicu.

Design and development

After flying his glider in Binținți, Aurel Vlaicu moved to the Kingdom of Romania. With help from Romanian-Transylvanian expatriates in Bucharest, he obtained financial support to build his first powered airplane, following a number of demonstration flights with rubber-powered models in front of Romanian government officials and journalists.

On November 1, 1909, he began the construction of his first powered airplane, the A. Vlaicu Nr. I at the Army Arsenal in Bucharest.  The Romanian Ministry of War provided an initial grant of 2000 lei, and Minister of Public Education was paying Vlaicu a 300 lei monthly stipend.

The A. Vlaicu Nr. I flew for the first time on June 17, 1910, over Cotroceni airfield.

For his design, Aurel Vlaicu was granted in 1911 patents: AT60800, CH54597, DK15328, FR422554 and GB191026658.

Military Commission Report 

Below are the minutes after aerial demonstrations held by Aurel Vlaicu in August 1910 before a military commission :

A Vlaicu III. The A Vlaicu III was the world's first metal-built aircraft, designed and built in Romania prior to World War I. It was the third powered aircraft designed by pioneering Romanian aviator Aurel Vlaicu.

Design and development

Engineer and inventor Aurel Vlaicu, who was among the first pilots in Romania, began the design of the third in his series of powered aircraft in the second half of 1911. The design was based on his earlier A Vlaicu II. A nacelle underneath a parasol wing housed the pilot and a Gnome Gamma engine. Gears, chains and shafts drove two propellers, one in front of and one behind the wing; these turned in opposite directions to cancel each other's torque. Like Vlaicu's other designs, the A. Vlaicu III did not have ailerons. The pilot turned the aircraft by using the rudder, controlled by moving a tiller left or right; to control the elevators and make the aircraft go up and down, a steering wheel attached to the tiller was turned left or right.

At the time of Vlaicu's death in the crash of the A Vlaicu II in 1913, two A. Vlaicu IIIs were under construction for delivery to the Marconi Company. The British company was supposed to receive one for performance evaluation and experimentation with aerial radio, the other was supposed to remain in Romania. After Vlaicu's death, one of the two aircraft was completed by his friends Giovanni Magnani and Constantin Silisteanu; and was ready to fly in May 1914.

Operational history
Two test 'hops' covering a ground distance of 200–300 metres (220-330 yards) at a maximum altitude of about  were made in 1914 by pilot Petre Macavei at Cotroceni airfield. Military authorities of the time refused permission to continue the tests. At a later date, pilots Mircea Zorileanu and Gheorghe Negrescu obtained permission from the Romanian Minister of War to modify the controls of the aircraft and continue the experiments, but it never flew again.

In 1916, during the German occupation of Bucharest, an A Vlaicu III was seized and shipped to Germany. It was last seen in 1942 at an aviation exhibition in Berlin by Romanian military officers. However, no mention of it is made in records of the Berlin exhibition.

Michael A. Harrison. Michael A. Harrison is a computer scientist, in particular a pioneer in the area of formal languages.

Biography

Michael A. Harrison (born in Philadelphia, Pennsylvania, U.S.) studied electrical engineering and computing for BS and MS at the Case Institute of Technology, and then received a PhD from the University of Michigan in Communication Sciences. He was assistant professor from 1963 to 1966 at the University of Michigan, and then joined the faculty of the E.E. Dept at the University of California at Berkeley, where he was an associate professor from 1966 to 1971, and a full professor from 1971 to 1994.

In the 1960s, he worked with Sheila Greibach, Gene Rose, Ed Spanier, and Joe Ullian in a research group formed and led by Seymour Ginsburg, dedicated to formal language theory and the foundations of Computer Science. The work that came out of this group distinguished Computer Science theory from other fields. It also brought the field of formal language theory to bear on programming language research.

In 1975, he developed the HRU security model (named after its authors Harrison, Ruzzo, Ullman), an operating system level computer security model dealing with the integrity of access rights in the system.

With his Ph.D. student Pehong Chen at Berkeley, he founded the "Gain Technology" company (acquired by Sybase in 1992).

Currently, he is professor emeritus and also professor in the graduate school at Berkeley.

Personal life 
Harrison is married to Susan L. Graham, the Pehong Chen Distinguished Professor Emerita in the Computer Science Division of the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley.

Genoa Erzelli GREAT Campus. The GREAT Campus is a science technology park located on the Erzelli hill in Genoa, in northwest Italy. The park is partly under ongoing construction and partly already working. At the moment, it hosts several high tech corporations such as Ericsson, Siemens, and Esaote, in addition to a robotics laboratory of the Istituto Italiano di Tecnologia (IIT) and other companies.

In 2026, the GREAT Campus will host the new Faculty of Engineering of the local Università di Genova.

History

The foundation

In the early 2000s, a group of entrepreneurs and managers gathered in the Ligurian Dixet association, constitute the Genova High Tech S.p.A. company aimed precisely to the realization of the technology park.
The company is led by Carlo Castellano, CEO of Esaote S.p.A., and Giuseppe Rasero, former director of the Institute for Industrial Reconstruction (IRI).
Your company has, among others, shares of Intesa Sanpaolo, Banca Carige, Aurora Construction, Coop Liguria, Prometheus srl, Talea S.p.A. and EuroMilano S.p.A.

The construction

The Erzelli is an area about 0.44 km2 wide located in Genoa between the neighborhoods of Sestri Ponente and Cornigliano. It was created by clipping the top of the Monte Guano and using the resulting material for the construction of the Genoa Cristoforo Colombo Airport. Thanks to a major urban improvement project, it is set to house the Erzelli Science and Technology Village which will give the city of Genoa an innovative high technology, research, training and business center. It is destined to change Genoa's image while giving the city a 100 thousand square metre park with many facilities and 200 thousand square meters of green areas along the slopes of Monte Guano. Sports, leisure and entertainment facilities will be set up here.

The Master Plan

The Master Plan foresees that some 70% of the Village will be used for high tech and training/education with around 200 businesses established, 15,000 new users including 5,000 students and the creation of at least 6,000 jobs for highly qualified persons. The residential areas will be developed in the most scenic locations and shall be close to parks and facilities. Genoa University Faculty of Engineering, buildings for high tech businesses, urban village/park, recreation facilities, commercial services, residences for students and researchers.

INtime. The INtime Real Time Operating System (RTOS) family is based on a 32-bit RTOS conceived to run time-critical operations cycle-times as low as 50μs. INtime RTOS runs on single-core, hyper-threaded, and multi-core x86 PC platforms from Intel and AMD. It supports two binary compatible usage configurations; INtime for Windows, where the INtime RTOS runs alongside Microsoft Windows®, and INtime Distributed RTOS, where INtime runs one.

Like its iRMX predecessors, INtime is a real-time operating system, and like DOSRMX and iRMX for Windows, it runs concurrently with a general-purpose operating system on a single hardware platform.

History

Initial Release

INtime 1.0 was originally introduced in 1997 in conjunction with the Windows NT operating system. Since then it has been upgraded to include support for all subsequent protected-mode Microsoft Windows platforms, Windows XP to Windows 10.

INtime can also be used as a stand-alone RTOS. INtime binaries are able to run unchanged when running on a stand-alone node of the INtime RTOS. Unlike Windows, INtime can run on an Intel 80386 or equivalent processor. Current versions of the Windows operating system generally require at least a Pentium level processor in order to boot and execute.

Version 2.2

After spinning off from Radisys in 2000 development work on INtime continued at TenAsys Corporation. In 2003 TenAsys released version 2.2 of INtime.

Notable features of version 2.2 include:
 Real-time Shared Libraries, or RSLs, which are the functional equivalent of the Windows Dynamically Loaded Libraries, or DLLs.
 Support for the development of USB clients, and USB host control drivers for OHCI, UHCI and EHCI (USB 2.0) devices.
 A new timing acquisition and display application called ""INscope"" is released.

Industrial steam locomotive. An industrial steam locomotive is a type of steam locomotive which primarily ran on industrial railways to serve a company by transporting or assisting the manufacturing products of that particular company's produce. Industrial railways often transported items such as coal, iron, slate and workers to aid production. In many countries, industrial steam serving coal mines in particular, lasted significantly longer than the nations otherwise mainline steam traction, due to the readily available fuel.

UK 
The United Kingdom is known for its widespread use of internal and external railways of many different gauges. The most common industrial gauge in the UK was standard gauge. This used  4 ft 8 1⁄2 the most common gauge throughout the world.

Tetranitratoaluminate. Tetranitratoaluminate is an anion of aluminium and nitrate groups with formula [Al(NO3)4]− that can form salts called tetranitratoaluminates. It is unusual in being a nitrate complex of a light element.

Related substances
By substituting boron for aluminium tetranitratoborates result. Aluminium can coordinate more nitrates resulting in pentanitratoaluminates and hexanitratoaluminates.

By replacing nitrate with perchlorate, the tetraperchloratoaluminate ion results.

Formation
When hydrated aluminium nitrate reacts with dinitrogen pentoxide it forms a nitronium salt: [NO2]+[Al(NO3)4]−.

A way to make a tetranitratoaluminate salt of a cation is to treat the chloride of the cation and aluminium chloride with liquid dinitrogen tetroxide pure or dissolved in nitromethane. The reaction is started at liquid nitrogen temperatures and then warmed up. Dark red nitrosyl chloride is formed as a byproduct. The byproducts and solvents can then be evaporated. The tetramethylammonium salt can form this way.

Properties
The tetranitratoaluminate group has two bidentate nitrate groups attached in a square around the aluminium, and with two other monodentate nitrates attached via one oxygen only, perpendicular, up and down from the square.

Tetranitratoaluminate salts are not completely stable and can decompose to the nitrates and aluminium oxynitrates.

When nitronium tetranitratoaluminate is sublimed it can form anhydrous aluminium nitrate.

Nitronium tetranitratoaluminate dissolved in a nitric acid and dinitrogen pentoxide mixture yields the hexanitratoaluminate complex. In water is it converted to the hexaaqua complex with six water molecules replacing the nitrate groups.

Examples
Tetraethyl ammonium tetranitratoaluminate along with nitronium tetranitratoaluminate were the first to be discovered.

1-Ethyl-4,5-dimethyl-tetrazolium tetranitratoaluminate is an oxygen balanced ionic liquid, This liquid salt is stable when moisture is excluded. It is soluble in methyl nitrate. It solidifies to a glass at −46 °C, starts to slowly decompose at 75 °C, and inflames, without oxygen required, around 200 °C. When it burns it produces aluminium oxide, nitrogen, water and carbon monoxide. It is being proposed as a rocket propellant, because it has better performance than hydrazine. Rubidium and caesium also form salts.

Tetramethyl ammonium tetranitratoaluminate forms monoclinic crystals with a = 12.195 Å, b = 9.639 Å, c = 12.908 Å, α = 90°, β = 110.41°, γ = 90°, and a formula weight of 349.17 (4 equivalents) per unit cell. The unit cell volume is 1422 Å3 and the calculated density 1.631 g/cm3.

VAH-123. VAH-123, nicknamed the Professionals from 1961 onward, was a Heavy Attack Squadron of the U.S. Navy, based at NAS Whidbey Island, Washington. It was established on 15 June 1957 as Heavy Attack Training Unit, Pacific (HATUPAC). On 29 June 1959 it was redesignated as VAH-123. The squadron was disestablished on 1 February 1971, after eleven years of service.

Operational history
During its time, the squadron flew many different aircraft types, beginning in the years shown: Lockheed P-2 Neptune (1957); Douglas F3D Skyknight (1957); Grumman F-9 Cougar (1958); Douglas A-3 Skywarrior (1958, with several variants over the years); and Grumman A-6 Intruder (1966).

The unit was established to train personnel for the heavy attack mission, including the pilots, bombardier/navigators and aircrewmen. It retained that mission throughout its life. In 1959, it incorporated maintenance training into its mission, thereby providing a complete training program for all aspects of the heavy attack community's operational requirements.

In 1967, VAH-123 was relieved of its mission of replacement training in the A-6 Intruder when VA-128 was established as a separate squadron and assumed that job. When VAH-123 was disestablished, the mission of replacement training for the A-3/KA-3B was transferred to VAQ-130.
