HTW Berlin. Hochschule für Technik und Wirtschaft (University of Applied Sciences for Engineering and Economics) or HTW Berlin in Berlin, Germany is the largest public University of Applied Sciences in Berlin and Eastern Germany. It has over 13,000 students and 75 programs in areas of engineering, computer science, business, culture and design. At 26.4%, HTW Berlin has one of the highest proportions of international students in Germany.

In some research-intensive and innovative departments, the HTW Berlin exercises the rights to award doctorates.

History 

HTW Berlin is the result of the merger of various institutions.

1874 – The founding of the Fachschule für Dekomponieren, Komponieren und Musterzeichnen (School of Engineering and Technical Drawing), which later became the Berlin School of Textiles and Fashion. It then became the Engineering School of Clothing Technology, and was incorporated into the Engineering College of Berlin (Ingenieurhochschule Berlin) in 1990.

1948 – the Engineering School for Mechanical Engineering, Electrical Engineering, and Civil Engineering was founded. This was renamed the Engineering College of Berlin in 1988.

1991 – Technische Fachhochschule Berlin (TFH, now Berliner Hochschule für Technik) was charged with founding the FHTW, unifying the Engineering College and other colleges as well as the HfÖ College of Economics, located at five different places around the former East Berlin. The TFH was given responsibility for setting up the administration and hiring new teachers, although much of the staff remained with their respective schools.

1994 – FHTW was formally declared independent.

1996 – integration of the University of Applied Sciences German Telecom into the school.

2009 – name changed from FHTW to HTW Berlin and official opening of the completed Wilhelminenhof Campus.

2019 – HTW celebrated its 25th anniversary.

Server-sent events. Server-Sent Events (SSE) is a server push technology enabling a client to receive automatic updates from a server via an HTTP connection, and describes how servers can initiate data transmission towards clients once an initial client connection has been established. They are commonly used to send message updates or continuous data streams to a browser client and designed to enhance native, cross-browser streaming through a JavaScript API called EventSource, through which a client requests a particular URL in order to receive an event stream. The EventSource API is standardized as part of HTML Living Standard by the WHATWG. The media type for SSE is text/event-stream.

All modern browsers support server-sent events: Firefox 6+, Google Chrome 6+, Opera 11.5+, Safari 5+, Microsoft Edge 79+.

History 
The SSE mechanism was first specified by Ian Hickson as part of the "WHATWG Web Applications 1.0" proposal starting in 2004. In September 2006, the Opera web browser implemented the experimental technology in a feature called "Server-Sent Events".

Example 
var source = new EventSource('updates.cgi');
source.onmessage = function (event) {
  alert(event.data);
};

Oliver OC-9. The Oliver OC-9 was the first tractor crawler by Oliver Farm Equipment Company to employ the use of a torque converter. Along with the OC-96 variant, this model was introduced in 1959 as the final model in the OC series, marking a significant advancement in the company's technological standards.

The bulldozer originally sold for approximately . A valuation guide published in 2001 listed the current value of an OC-9 crawler in excellent condition as .

Powertrain
Over its lifetime, the OC-9 had several different models of engines, both gasoline powered and diesel powered. In 1960, the crawler was fitted with a 4-cylinder, , 62 hp Hercules diesel engine. The same year, the OC-9 introduced Oliver's Trans-O-Matic power-shift transmission, the case made of cast alloy steel. The hydrostatic transmission allowed for on-the-go changes between high and low ranges and also the ability to have one drive sprocket in forward and the other in reverse, something not possible with clutch type crawlers. The transmission, along with power steering and instant reverse, made the crawler easily maneuverable. While a conventional clutch type bulldozer only allows for the engine's kinetic torque to be transmitted to the ground, a converter type set up allows the engine to build static torque and transfer more power to the ground.

Blade and other attachments
The OC-9 was fitted with a three-meter blade. Its design allowed for angling, a crucial design factor used in grading roads. Other attachments included a log winch or 3-Tyne multi-shank ripper. The OC-96 was fitted with a  bucket.

Variants
Over the years the OC-9 was in production, there were only slight modifications and improvements made to the design. The most notable were the blade push trunnions and hydraulic ram mounting positions. The only real variant of the OC-9 was a track loader designated the OC-96, built on the same design as the OC-9. The OC-96 was modified slightly to allow for the loader configuration: the final drives were rotated slightly to allow the position of the tracks to be farther in front of the machine. The track frames were lighter duty, and some changes to the chassis allowed the loader arms to be fitted.

Zenair CH 200. The Zenair Zenith CH 200 and CH 250 are a family of Canadian single-engined homebuilt light aircraft. It is a low-winged single engine monoplane, that was first flown in France in 1970, with kits being made by the Canadian company Zenair from 1974, with hundreds built and flown.

Development and design
In October 1968, the French aeronautical engineer Chris Heintz, who worked for Avions Pierre Robin, started work on the design of a two-seat all-metal light aircraft suitable for amateur construction, the Zenith, with the prototype making its maiden flight on 22 March 1970.

Heintz migrated to Canada in 1973, and set up Zenair in 1974 to sell plans and kits of the Zénith. The Zenith, which gained the designation Zenith CH 200 when Heintz produced plans for larger and smaller derivatives, is a low-winged cantilever monoplane of all metal construction. The pilot and passenger sit side by side under a clear, sideways-opening plexiglas canopy, while the aircraft is fitted with a fixed nosewheel undercarriage. It is designed to be powered by a single piston engine of between 85 and 160 hp (63.5 and 119 kW).

The first Zenith to be built in North America flew in October 1975, and by 1976, over 300 plans had been sold. Plans continued to be available in 1999, by which time hundreds were flying.

At the 1976 EAA Convention in Oshkosh, Wisconsin the factory used volunteer labour to build and fly a CH 200 in eight days, using 550 person-hours.

Variants

Zenair CH 200
Initial version. Could be built as a cross country cruiser with an engine of  or as an aerobatic trainer with modifications and a powerplant producing . The aircraft can be constructed as a taildragger or on tricycle gear and flown as a skiplane or on floats.

Propulsive wing. The propulsive wing is a patented UAV (unmanned aerial vehicle) design concept developed in the 2000s with extremely high lift and internal volume. The propulsive wing could be used to develop a new class of aircraft based on an embedded, distributed cross-flow fan propulsion system within a thick wing. The fan, partially embedded within the airfoil section, draws the flow in from the suction surface and exhausts at the trailing edge. In cruise, the combination of distributed boundary-layer ingestion and wake filling increase propulsive efficiency, while distributed vectored thrust provides substantial improvements in pressure drag.

At high angle of attack, with the fan off, the airfoil fully stalls, and a large wake is present. However, when the fan is turned on, the suction effect of the fan draws the air in, completely eliminating the wake. The result is a significant increase in lift. In addition to maintaining flight at very high angles of attack, lift and drag forces can be managed through circulation control. In particular, if the exhaust is deflected downward as it leaves the propulsor, a circulation control effect is realized. Even at low angle of attack, high lift coefficients have been shown with CFD and validated with wind tunnel experiments.

The propulsive wing controls pitch and roll controls through vectored thrust. By distributing multiple thrust deflection flaps along the span, the high-velocity jet doubles as both the main thrust producer, as well as roll and pitch control. Collective changes in the trailing edge flaps control pitch, and spanwise differential changes control roll. Due to the circulation control effect of vectored thrust, a substantial rolling moment can be produced with very little control input.

In 2007 the cross-flow fan propulsive wing technology won first prize in the graduate category at the American Institute of Aeronautics and Astronautics International Student Conference.

Several international groups have investigated the propulsive wing technology and presented their results at conferences. A group from Bauhaus Luftfahrt in Munich, Germany presented computational work demonstrating the application of the cross-flow fan propulsive wing for regional aircraft applications. A research group from Nanjing, China built and tested a propulsive wing wind tunnel model, demonstrating the high lift and low drag capabilities of the design.

Hell's Horizon. Hell's Horizon is a 1955 American war film directed by Tom Gries. The film stars John Ireland and Marla English. Hell's Horizon recounts the story of a bomber crew in the Korean War.

Plot
During the Korean War, United States Air Force Captain John Merrill (John Ireland) is the pilot of a Boeing B-29 Superfortress bomber. Merrill is based in Okinawa and is ordered to destroy a Yalu River bridge in Korea. The mission is continually delayed due to bad weather. His co-pilot (Bill Williams) has to step in when the bored and frustrated crew members begin to fight over Sammi (Marla English), a local woman who is employed as a laundress at their base.

When the weather finally clears over the target, Merrill is ordered to attack the strategic bridge, but with only cloud cover as his protection. The North Koreans are prepared, and anti-aircraft guns hit the bomber as it descends out of the clouds. The attack is a success, but some crew members are killed, including "Jockey" (Chet Baker), the popular trumpeter of the base. Others on board are wounded. Merrill has to contend not only with the damaged bomber, but also flying through a deadly storm.

The bomber returns to base with extensive damage and only one engine still working, so Merrill has to make a "pancake" landing. The survivors make it back in time to hear the announcement of Sammi's engagement to one of the crew, Sgt. "Buddy" Lewis (Larry Pennell).

Cast
 John Ireland as Capt. John Merrill
 Marla English as Sammi
 Bill Williams as Paul Jenkins
 Hugh Beaumont as Sgt. Al Trask
 Larry Pennell as Sgt. "Buddy" Lewis
 Chet Baker as "Jockey"

Production
Hell's Horizon relied on a large amount of stock footage.

Reception
Despite its release only a few years after the end of the Korean War, Hell's Horizon was no more than a typical B war film. Reviewer Alun Evans summed it up as a "standard action drama of a single bomber raid in the Korean conflict with no redeeming features." In Leonard Maltin's review, he merely noted, "Interaction among men of bombing squad in the Korean War."

Moisant Aviation School. The Moisant Aviation School was a school in the early days of aviation founded by Alfred Moisant at Hempstead, Long Island, New York. Alfred and his brother John Bevins Moisant formed the Moisant International Aviators, a flying circus which toured the United States, Mexico and El Salvador. John had learned to fly in France with Louis Bleriot but died in 1910 in an accident. The school had six Bleriot monoplanes equipped with 50 horse power Gnome motors.

Many early aviators learned to fly or perfected their skills at this school, among them Harriet Quimby first American pilot, Matilde E. Moisant, John's and Alfred's sister and the second woman to obtain a pilot's license in the United States, the Aldasoro brothers Juan Pablo and Eduardo, two Mexican pilots who had started to fly gliders in 1909, Dante Nannini Sandoval, first Guatemalan Pilot, and Bernetta Adams Miller, the fifth licensed woman pilot in the U.S.  Under the auspices of the school, Bernetta Miller demonstrated the Moisant/Bleriot monoplane to the U.S. Army in October, 1912, and subsequently made an unsuccessful attempt on the women's altitude record.

An instructor at the school, Albert Jewell disappeared on 13 October 1913 on flight from the Hempstead airfield to Oakwood, Staten Island, NY to take part in an air race; he is assumed to have come down at sea off the south shore of Long Island.

Zenair CH 100. The Zenair Mono-Z CH 100 is a single-seat, single-engined Canadian light aircraft of the 1970s, that was designed by Chris Heintz.  It is a smaller version of the Zenair CH 200 with a less powerful engine, which was sold as a homebuilt aircraft by Zenair.

Development and design

After emigrating to Canada and setting up Zenair to sell plans and kits for amateur construction of his Zenith two-seat-light aircraft, the German aircraft designer Chris Heintz started design of a smaller, single-seat development of the Zenith, the Mono-Zenith. The Mono-Z CH 100 is similar to the Zenith that preceded it, a low-winged cantilever monoplane of all metal construction. The aircraft features a large cockpit for taller pilots, with a pilot and baggage combined weight allowance of  and removable wings for storage and towing the aircraft behind a car. The factory claimed a build time of 600 hours. It is designed to be powered by engines from 45 to 100 hp (33.5 to 74.5 kW).

The first CH 100 made its maiden flight on 8 May 1975, powered by a 55 hp (41 kW) Volkswagen air-cooled engine of 1600 cc, with 110 sets of plans and kits sold by 1982.  Zenair continued to produce kits until 1988.

Operational history
A total of three CH 100s were registered in Canada since 1987 and none are registered in 2010.
