Technology Demonstration
A technology demonstration (or tech demo), also known as demonstrator model, is a prototype, rough example or an otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users. Computers and gaming Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles, in both software and hardware development. * Computer game developers use tech demos to rouse and maintain interest to titles still in development (because game engines are usually ready before the art is finished) and to ensure functionality by early testing.

Ørsted (satellite)
Ørsted is Denmark's first satellite, named after Hans Christian Ørsted (1777–1851), a Danish physicist and professor at the University of Copenhagen, who discovered electromagnetism in 1820. Objectives The spacecraft primary science objectives were to perform highly accurate and sensitive measurements of the geomagnetic field and to perform global monitoring of the high energy charged particle environment. Instruments The instrumentation consisted of two magnetometers ( proton precession and fluxgate), a star imager for attitude determination, a solid-state charged particle detector package, and a GPS receiver. The Science Instrument Team is responsible for the design of the instruments, while the Science Team is responsible for the science mission planning and international science participation. The science data obtained during the planned one-year mission will be used to derive an updated model of the geomagnetic field and its secular variation and to study the magneto ...

AAU CubeSat
AAU CubeSat was a CubeSat built and operated by students from Aalborg University in Denmark. AAU CubeSat was launched on 30 June 2003 from the Plesetsk Cosmodrome on a Russian Rockot launch vehicle. The satellite was alive for two and a half months, during which some data was received on Earth; however, it was never possible to establish a solid communication link. It is thought that there was a problem with the on-board transmitter. Spacecraft The aluminum frame was milled from a solid block to ensure that a strong and lightweight frame was created. There are four rails to allow the satellite to slide in and out of the frame. The four rails are connected by other aluminum pieces. The subsystem circuit boards are screwed onto these pieces. Carbon-fiber plates are then glued onto the outside of the frame to support the solar panels and attitude control coils. The solar panels and attitude control coils are glued to the plates. Payload AAU CubeSat's payload is a CMOS digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SSETI Express (satellite)
SSETI Express was the first spacecraft to be designed and built by European students and was launched by the European Space Agency. SSETI Express (Student Space Exploration & Technology Initiative) is a small spacecraft, similar in size and shape to a washing machine. On board the student-built spacecraft were three CubeSat picosatellites, extremely small satellites weighing around one kg each. These were deployed one hour and forty minutes after launch. Twenty-one university groups, working from locations spread across Europe and with very different cultural backgrounds, worked together via the internet to jointly create the satellite. The expected lifetime of the mission was planned to be 2 months. SSETI Express encountered an unusually fast mission development: less than 18 months from kick-off in January 2004 to flight-readiness. Picosatellites The three picosatellites on board the spacecraft were: * Xi-V (X-factor investigator-V) from University of Tokyo, Japan Its ...

7075 Aluminium Alloy
7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly better corrosion resistance than the alloys from the 2000 series. It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts. 7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc, 2.1–2.5% magnesium, 1.2–1.6% copper, and less than a half percent of silicon, iron, manganese, titanium, chromium, and other metals. It is produced in many tempers, some of which are 7075-0, 7075-T6, 7075-T651. The first 7075 was developed in secret by a Japanese company, Sumitomo Metal, in 1935, but reverse engineered by Alcoa in 1943, after examin ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...
