Straubing
Straubing () is an independent city in Lower Bavaria, southern Germany. It is seat of the district of Straubing-Bogen. Annually in August the Gäubodenvolksfest, the second largest fair in Bavaria, is held. The city is located on the Danube forming the centre of the Gäuboden. History The area of Straubing has been continuously settled since the Neolithic. The conquest by the Romans in 16–14 BC had a dramatic impact on the whole region. Even today many traces of the 400-year Roman occupation can be found: for example, the famous 'Römerschatz' (Roman treasure) which was excavated in 1950 and which is shown in the Gäubodenmuseum. ''Sorviodurum'', as the Romans called it, was an important military support base. After the fall of the Roman Empire Straubing became a centre of settlement of the Bavarii, mostly around St. Peter's Church (built in the 9th century) between Allachbach and Danube. According to the customs of the Bavarii the settlement was named after their leader ''S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fritz Erich Fellgiebel (4 October 1886 – 4 September 1944) was a German Army general of signals and resistance fighter in the 20 July plot to assassinate Nazi dictator Adolf Hitler. In 1929, Fellgiebel became head of the cipher bureau (german: Chiffrierstelle) of the Ministry of the Reichswehr, which would later become the OKW/Chi. He was a signals specialist and was instrumental in introducing a common enciphering machine, the Enigma machine. However, he was unsuccessful in promoting a single cipher agency to coordinate all operations, as was demanded by OKW/Chi and was still blocked by Joachim von Ribbentrop, Heinrich Himmler and Hermann Göring until autumn 1943. It was not achieved until General Albert Praun took over the post. Military career Fellgiebel was born in Pöpelwitz (Present-day Popowice in Wrocław, Poland) in the Prussian Province of Silesia.

G7es Torpedo
The G7es (T5) ''"Zaunkönig"'' ("wren") was a passive acoustic torpedo employed by German U-boats during World War II. It was called the GNAT (German Navy Acoustic Torpedo) by the British. Description The forerunner of the ''Zaunkönig'' was the G7e/T4 Falke, codename "Falcon," which was introduced in March 1943, but saw limited use for trial and was rapidly phased out of service in favor of the later model that received a number of significant enhancements. It was faster, had more range, possessed a magnetic or contact detonator and could be equipped with a percussion pistol. The T5 torpedo was capable of travelling at 24 knots (44 km/h) and had an effective range of about 5000 metres against convoy escorts vessels proceeding at speeds between 10 (18 km/h) and 18 knots (33 km/h). The homing system consisted of two hydrophone receivers and altered the direction of the rudder via an electropneumatic device. The acoustic homing torpedo was specifically designed as ...

Franconia
Franconia (german: Franken, ; Franconian dialect: ''Franggn'' ; bar, Frankn) is a region of Germany, characterised by its culture and Franconian dialect (German: ''Fränkisch''). The three administrative regions of Lower, Middle and Upper Franconia (largest cities, respectively: Würzburg, Nuremberg and Bamberg) in the State of Bavaria are part of the cultural region of Franconia, as are the adjacent Franconian-speaking South Thuringia, south of the Rennsteig ridge (largest city: Suhl), Heilbronn-Franconia (largest city: Schwäbisch Hall) in the state of Baden-Württemberg, and small parts of the state of Hesse. Those parts of the Vogtland lying in the state of Saxony (largest city: Plauen) are sometimes regarded as Franconian as well, because the Vogtlandian dialects are mostly East Franconian. The inhabitants of Saxon Vogtland, however, mostly do not consider themselves as Franconian. On the other hand, the inhabitants of the Hessian-speaking parts of Lower Franconia ...

Feuerstein Castle
Feuerstein Castle (german: Burg Feuerstein) lies at the edge of the so-called Lange Meile near Ebermannstadt in the county of Forchheim in the south German state of Bavaria. It was built in 1941 by Oskar Vierling as a laboratory for researching High Frequency technology and electroacoustics and was used until 1945 by 250 employees for research into weapons and communication technology as part of the German armaments programme during the Second World War. At the end of the war the castle was seized by American soldiers, from 1946 it was rented by the Archdiocese of Bamberg under Jupp Schneider and sold in 1949. Since then the castle and the entire estate have been in use as a Roman Catholic youth and conference centre. History Oskar Vierling was looking for a central location for his laboratories. The choice fell on a hill called the Feuerstein. Its design as a castle blended well into the countryside of Franconian Switzerland and was chosen for camouflage reasons. During the w ...

Acoustical Engineering
Acoustical engineering (also known as acoustic engineering) is the branch of engineering dealing with sound and vibration. It includes the application of acoustics, the science of sound and vibration, in technology. Acoustical engineers are typically concerned with the design, analysis and control of sound. One goal of acoustical engineering can be the reduction of unwanted noise, which is referred to as noise control. Unwanted noise can have significant impacts on animal and human health and well-being, reduce attainment by students in schools, and cause hearing loss. Noise control principles are implemented into technology and design in a variety of ways, including control by redesigning sound sources, the design of noise barriers, sound absorbers, suppressors, and buffer zones, and the use of hearing protection (earmuffs or earplugs). Besides noise control, acoustical engineering also covers positive uses of sound, such as the use of ultrasound in medicine, programming digita ...
