Semmering Base Tunnel
The Semmering Base Tunnel is a railway tunnel under construction between Gloggnitz and Mürzzuschlag in Austria underneath the Semmering Pass. The existing route is 41 km in length and the Semmering Base Tunnel will be 27.3 km in length. The new route will offer time savings of up to 30 minutes, partly on account of the shorter route and partly on account of the higher speed limit (maximum 250 km/h). Construction began on 25 April 2012 and the link is expected to enter operational service in 2030, delayed from the original estimate of 2026. The main benefit of the new tunnel will be increased ease of use for freight traffic. The gradients of the traditional routes requires the use of two locomotives; the reduced gradient of the new link will enable the transit of freight traffic using just one locomotive. The Semmering Base Tunnel and the Koralm Railway in combination will enable freight transit across the whole southern line with just one locomotive. Currently, t ...

Gloggnitz
Gloggnitz is a mountain town in the Neunkirchen district of Lower Austria, Austria. Gloggnitz is situated in the south-western part of the Vienna Basin in Lower Austria. It is surrounded by the highest mountains in Lower Austria, Mount Rax (2007m / 6585 ft) and Mount Schneeberg (2076m / 6811 ft). The town is also a major traffic junction: Gloggnitz is situated on the main Südbahn (the important rail route between Vienna and Trieste in Italy) and the S6 motorway. Gloggnitz is famous for producing two of Austria's most distinguished Federal Presidents. Federal President Dr Michael Hainisch (1858–1940) and the Chancellor of State and later Federal President Dr Karl Renner (1870–1950) were both Gloggnitz citizens. Dr Karl Renner spent 42 years of his life in Gloggnitz (up until his death in 1950). On the occasion of the anniversary of his hundredth birthday a monument was erected in Dr Karl Renner Square. A museum in his former residence also commemorates the life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain "cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...

Ventilation (architecture)
Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives. The intentional introduction of outdoor air is usually categorized as either mechanical ventilation, natural ventilation, or mixed-mode ventilation (hybrid ventilation). * Mechanical ventilation is the intentional fan driven flow of outdoor air into a building. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust fans (which draw air out of building and thereby cause equal ventilation flow into a building), or a combination of both. Mechanical ventilation is often provided by equipment that is also used to heat and cool a space. * Natural ventilation is the intentional passi ...

Environmental Control
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh ai ...

Aerodynamic
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis f ...

Amberg Engineering
Amberg () is a town in Bavaria, Germany. It is located in the Upper Palatinate, roughly halfway between Regensburg and Bayreuth. In 2020, over 42,000 people lived in the town. History The town was first mentioned in 1034, at that time under the name Ammenberg. It became an important trading centre in the Middle Ages, exporting mainly iron ore and iron products. In 1269, together with Bamberg, the town became subordinate to the Wittelsbach dynasty that ruled Bavaria. In 1329 the town and the entire region fell to the Palatinate branch of the Wittelsbach family. The region adopted the name Upper Palatinate.
