Arsenal (Vienna)
The Vienna Arsenal, object 1
(Pictures you can see by clicking on the link at the end of page!)
The Arsenal in Vienna is a former military complex in the southeast of the city, located in the 3rd district of Vienna. The mighty, consisting of several brick buildings facility is located on a rectangular plan on a hill south of the Country Road Belt (Landstraßer Gürtel).
Meaning
The Arsenal is the most important secular assembly of Romantic Historicism in Vienna and was conducted in Italian-Medieval and Byzantine-Moorish forms. Essentially the complex is preserved in its original forms; only the former workshop buildings within the bounding, from the the outside visible wings were replaced by new constructions.
History to 1945

The complex, with a total of 31 "objects" (buildings) was built from 1849 to 1856 on the occasion of the March Revolution of 1848 and was the first building of the fortress triangle, replacing the old Vienna's city walls, with the Rossauer Barracks and the now-defunct Franz Joseph barracks at Stubenring. These buildings should not serve to deter foreign enemies from the city, but to secure state power in the event of revolutionary upheavals in Vienna. The decision to build the Arsenal, it came from the 19-year-old Emperor Franz Joseph I who on 2 December 1848 had come to the throne.
The design for the Imperial Artillery Arsenal came from General Artillery Director Vincenz Freiherr von Augustin, to which, subsequently, the site management had been transferred. Under his leadership, the buildings under assignment of sectors have been planned of the architects Carl Roesner, Antonius Pius de Riegel, August Sicard von Sicardsburg, Eduard van der Nüll, Theophil von Hansen and Ludwig Förster and built by the company of the architect Leopold Mayr.
From 1853 to 1856, Arsenal church was built by the architect Carl Roesner. The K.K. Court Weapon Museum, later K.K. Army Museum, now Museum of Military History, housed in a separate representative free-standing wing, was completed structurally in 1856, but was only in 1869 for the first time accessible.
For the construction of the Arsenal 177 million bricks were used. Construction costs totaled $ 8.5 million guilders. In the following years, there have been extensions. During the two world wars, the complex served as a weapons factory and arsenal, especially as barracks.
The record number of employees in Arsenal was reached in the First World War, with around 20,000 staffers. After 1918, the military-industrial operation with own steel mill was transformed into a public service institution with the name "Austrian Factories Arsenal". However, there were almost insoluble conversion problems in the transition to peacetime production, the product range was too great and the mismanagement considerable. The number of employees declined steadily, and the company became one of the great economic scandals of the First Republic.
By the fall of 1938, the area belonged to the 10th District Favoriten. However, as was established during the "Third Reich" the Reich District of Greater Vienna, became the arsenal complex and the south-east of it lying areas in the wake of district boundary changes parts of the 3rd District.
During the Second World War, in the Arsenal tank repair workshops of the Waffen-SS were set up. In the last two years of the war several buildings were severely damaged by bombing. During the Battle of Vienna, in the days of 7 to 9 April 1945, was the arsenal, defended by the 3rd SS Panzer Division "Totenkopf", focus of the fighting, the Red Army before its victory facing heavy losses.
History since 1945
Ruins of the object 15 after the air raids 1944
Deposits at the Arsenal Street
After heavy bomb damages during the Second World War, the buildings of the Arsenal were largely restored to their original forms.
In the southern part and in the former courtyard of the arsenal several new buildings were added, among them 1959-1963 the decoration workshops of the Federal Theatre designed by the architects Erich Boltenstern and Robert Weinlich. From 1961 to 1963, the telecommunications central office was built by the architect Fritz Pfeffer. From 1973 to 1975 were built operation and office building of the Post and Telephone Head Office for Vienna, Lower Austria and Burgenland (now Technology Centre Arsenal of Telekom Austria) with the 150-meter high radio tower in Vienna Arsenal according to the plans of architect Kurt Eckel. In the 1990s, a rehearsal stage of the Castle Theater (Burgtheater) was built according to plans by Gustav Peichl.
Also the Austrian Research and Testing Centre Arsenal, now Arsenal Research, which has made itself wordwide a celebrity by one of the largest air chambers (now moved to Floridsdorf - 21st District), was housed in the complex. A smaller part of the complex is still used by the Austrian army as a barracks. Furthermore, the Central Institute for Disinfection of the City of Vienna and the Central Chemical Laboratory of the Federal Monuments Office are housed in the arsenal. The Military History Museum uses multiple objects as depots.
In one part of the area residential buildings were erected. The Arsenal is forming an own, two census tracts encompassing census district, which according to the census in 2001 had 2.058 inhabitants.
End of 2003, the arsenal in connection with other properties of the Federal Property Society (BIG - Bundesimmobiliengesellschaft) was sold to a private investor group. Since early 2006, the lawyer of Baden (Lower Austria, not far away from Vienna) Rudolf Fries and industrialist Walter Scherb are majority owners of the 72,000 m2 historic site that they want to refurbish and according to possibility rent new. Fries also plans to enlarge the existing living space by more than a half (about 40,000 m2).
An architectural design competition, whose jury on 28 and 29 in June 2007 met, provided proposals amounting to substantial structural changes in the complex. Such designed competition winner Hohensinn a futuristic clouds clip modeled after El Lissitzky's cloud bracket, a multi-level horizontal structure on slender stilts over the old stock on the outskirts of the Swiss Garden. The realization of these plans is considered unlikely.
Some objects are since 2013 adapted for use by the Technical University of Vienna: Object 227, the so-called "Panzerhalle" will house laboratories of the Institute for Powertrains and Automotive Technology. In object 221, the "Siemens hall", laboratories of the Institute for Energy Technology and Thermodynamics as well as of the Institute for Manufacturing Technology and High Power Laser Technology are built. In object 214 is besides the Technical Testing and Research Institute (TVFA) also the second expansion stage of the "Vienna Scientific Cluster" housed, of a supercomputer, which was built jointly by the Vienna University of Technology, the University of Vienna and the University of Agricultural Sciences.
Accessibility
The arsenal was historically especially over the Landstraßer Gürtel developed. Today passes southeast in the immediate proximity the Südosttangente called motorway A23 with it connection Gürtel/Landstraßer Hauptstrasse. Southwest of the site runs the Eastern Railway, the new Vienna Central Station closes to the west of the arsenal. Two new bridges over the Eastern Railway, the Arsenal Stay Bridge and the Southern Railway bridge and an underpass as part of Ghegastraße and Alfred- Adler-Straße establish a connection to the on the other side of the railway facilities located Sonnwendviertel in the 10th District, which is being built on the former site of the freight train station Vienna South Station.
On the center side is between Arsenal and Landstraßer Gürtel the former Maria Josefa Park located, now known as Swiss Garden. Here stands at the Arsenal street the 21er Haus, a branch of the Austrian Gallery Belvedere, on the center-side edge of the Swiss Garden has the busy suburban main railway route the stop Vienna Quartier Belvedere, next to it the Wiener Linien D (tram) and 69A (bus) run.
The Indy, code-named "Guinness", is a low-end workstation introduced on 12 July 1993. Developed and manufactured by Silicon Graphics Incorporated (SGI), it was the result of their attempt to obtain a share of the low-end computer-aided design (CAD) market, which was dominated at the time by other workstation vendors; and the desktop publishing and multimedia markets, which were mostly dominated at the time by Apple Computer. It was discontinued on 30 June 1997 and support ended on 31 December 2011.

Retrocomputing (a portmanteau of retro and computing) is the use of early computer hardware and software today. Retrocomputing is usually classed as a hobby and recreation rather than a practical application of technology; enthusiasts often collect rare and valuable hardware and software for sentimental reasons. However some do make use of it.[1] Retrocomputing often gets its start when a computer user realizes that expensive fantasy systems like IBM Mainframes, DEC Superminis, SGI workstations and Cray Supercomputers have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.
en.wikipedia.org/wiki/Retrocomputing
Con il termine retrocomputing si indica una attività di "archeologia informatica" che consiste nel reperire, specialmente a costi minimi, computer di vecchie generazioni, che hanno rappresentato fasi importanti dell'evoluzione tecnologica, ripararli se sono danneggiati, metterli nuovamente in funzione e preservarli.

A NASA computer model simulates the astonishing track and forceful winds of Hurricane Sandy.
Hurricane Sandy pummeled the East Coast late in 2012’s Atlantic hurricane season, causing 159 deaths and $70 billion in damages. Days before landfall, forecasts of its trajectory were still being made. Some computer models showed that a trough in the jet stream would kick the monster storm away from land and out to sea. Among the earliest to predict its true course was NASA’s GEOS-5 global atmosphere model. The model works by dividing Earth’s atmosphere into a virtual grid of stacked boxes. A supercomputer then solves mathematical equations inside each box to create a weather forecast predicting Sandy’s structure, path and other traits. The NASA model not only produced an accurate track of Sandy, but also captured fine-scale details of the storm’s changing intensity and winds. Watch the video to see it for yourself.

Elijah Snow is hired by Jakita Wagner to join Planetary, a four-man team (3 field agents and one mysterious backer known as "the Fourth Man") looking to uncover the hidden history of the world as "mystery archeologists." Their first mission: to explore a man-made cavern in the Adirondacks, the last known destination of Doc Brass, an adventurer from the 1930s and 1940s.
Elijah Snow is asked by Jakita Wagner to join Planetary -- a group of archaeologists who map the secret history of the world -- as their new field agent. He joins under the promise of a million dollars a year and record of him eliminated. He is introduced to The Drummer and goes on his first investigation that of going to view the secret base of a Renaissance Man and adventurer named Dr, Axel Brass; a man who may no longer need to eat or sleep. After arriving at the headquarters Elijah and Jakita see Brass still alive but with damaged legs Doc Brass then tells them that years ago in the forties he and his fellow adventurers had secretly gathered in the same base and had created a supercomputer that harassed the 196,833 universes and realign them and merge them, Doc Brass and his associates wished to use the device and the multiverse in a attempt to create a perfect world but failed when a group of people (JLA-like beings) from another universe used the computer to come to their universe. The other beings universe was dying and these beings attempted to take the other world and kill everyone on this Earth for their Earth's population a battle ensued and all were killed except Brass who suspects the years is 1970. Planetary crew cleans up Doc Brass' headquarters while he will be placed in care. Elijah tells Jakita how strange the world is while Jakita tells him "Let's keep it that way".
Elijah Snow is approached in a diner in the middle of the desert by Jakita Wagner, who attempts to recruit him into Planetary -- a group of archaeologists who map the secret history of the world -- as their new field agent, or "third man". He reluctantly joins under the promise of a million dollars a year and all public records of his life eliminated. He is introduced to The Drummer -- the final member of the field team -- and accompanies his teammates on an investigation of a secret Adirondacks base of Renaissance Man and adventurer Dr, Axel Brass.
Upon arriving at the mountain stronghold, Elijah and Jakita discover Brass still alive within the compound, having sustained crippling injuries to his legs many years ago. Brass tells them of his companions in the 1940s -- like-minded adventurers including Hark, Kevin Sack (Lord Blackstock), and the Dark Millionaire --and the supercomputer they built that harnessed the power of 196,833 universes in order to realign and merge them. In their attempt to use the device to create a perfect world, they opened a rift into another universe where seven strangers (a pastiche of the most iconic members of the Justice League) awaited them. These strangers came from a dying universe, and they desperately fought Brass and his companions in an attempt to overtake our reality and replace this Earth's population with their own. In the enusing battle, all combatants perished save for Brass, who stayed in the stronghold to defend it against potential incursions from other dimensions. Having long since overcome the need to eat or sleep and having learned to will his body to heal itself, he has maintained his vigil over the supercomputer ever since, estimating that the year is roughly 1970.
After his tale, the Planetary team cleans up Brass' headquarters and takes him into their care, setting up a watch on the supercomputer and archiving the contents of the fortress. Elijah comments to Jakita how strange the world is, to which Jakita responds, "Let's keep it that way"; this statement will become the mantra of the series going forward.
The issue is conceptually about the rise of superhero comics, which overthrew the pulp adventure tales of the day (represented by Doc Brass and his companions, who resemble classic characters such as Tarzan and The Shadow).
The Argonne Leadership Computing Facility (ALCF) major acquisition, the Blue Gene/P supercomputer, will boost the facility's total computing power to 556 teraflops, representing a fivefold increase in system capability. This advance will help to initiate the coming era of petascale computing and enable experts to answer questions that have confounded America's scientists for years.

Deep in space, giant galaxy clusters filled with vast clouds of hot, X-ray producing gas are assembled through supersonic collisions over billions of years. In order to better understand these astrophysical phenomena, called galaxy cluster mergers, scientists visualize them using supercomputers—resulting in this beautiful image.
ABOVE: Dark matter makes up the majority of the cluster material, up to 90% by mass, and the gravitational force of the dark matter dominates the physics of the merger. Most of the ordinary matter is in the form of a hot, diffuse plasma known as the intra-cluster medium. These gases interact directly, unlike the dark matter particles, whose motion is thought to be collisionless. However the mixing of the gas is completely driven by the violent orbital motion of the dark matter cores. Shown here are volume renderings of the gases (in blue and yellow) zoomed in so that detail of the structure involved in the interaction of dark matter particles and the gases can be seen.

Edited Chandra Space Telescope visualization of the center of the Milky Way Galaxy. Round variant in inverted grayscale.
Original caption: Want to take a trip to the center of the Milky Way? Check out a new immersive, ultra-high-definition visualization. This 360-movie offers an unparalleled opportunity to look around the center of the galaxy, from the vantage point of the central supermassive black hole, in any direction the user chooses.
By combining NASA Ames supercomputer simulations with data from NASA's Chandra X-ray Observatory, this visualization provides a new perspective of what is happening in and around the center of the Milky Way. It shows the effects of dozens of massive stellar giants with fierce winds blowing off their surfaces in the region a few light years away from the supermassive black hole known as Sagittarius A* (Sgr A* for short).
These winds provide a buffet of material for the supermassive black hole to potentially feed upon. As in a previous visualization, the viewer can observe dense clumps of material streaming toward Sgr A*. These clumps formed when winds from the massive stars near Sgr A* collide. Along with watching the motion of these clumps, viewers can watch as relatively low-density gas falls toward Sgr A*. In this new visualization, the blue and cyan colors represent X-ray emission from hot gas, with temperatures of tens of millions of degrees; red shows moderately dense regions of cooler gas, with temperatures of tens of thousands of degrees; and yellow shows of the cooler gas with the highest densities.
A collection of X-ray-emitting gas is seen to move slowly when it is far away from Sgr A*, and then pick up speed and whip around the viewer as it comes inwards. Sometimes clumps of gas will collide with gas ejected by other stars, resulting in a flash of X-rays when the gas is heated up, and then it quickly cools down. Farther away from the viewer, the movie also shows collisions of fast stellar winds producing X-rays. These collisions are thought to provide the dominant source of hot gas that is seen by Chandra.
When an outburst occurs from gas very near the black hole, the ejected gas collides with material flowing away from the massive stars in winds, pushing this material backwards and causing it to glow in X-rays. When the outburst dies down the winds return to normal and the X-rays fade.
The 360-degree video of the Galactic Center is ideally viewed through virtual reality (VR) goggles, such as Samsung Gear VR or Google Cardboard. The video can also be viewed on smartphones using the YouTube app. Moving the phone around reveals a different portion of the movie, mimicking the effect in the VR goggles. Finally, most browsers on a computer also allow 360-degree videos to be shown on YouTube. To look around, either click and drag the video, or click the direction pad in the corner.
Dr. Christopher Russell of the Pontificia Universidad Católica de Chile (Pontifical Catholic University) presented the new visualization at the 17th meeting of the High-Energy Astrophysics (HEAD) of the American Astronomical Society held in Monterey, Calif.
