AC4 (band)
AC4 is a Swedish hardcore punk band from Umeå, Sweden. Refused members Dennis Lyxzén and David Sandström had been talking about starting a new band for a long time. In the spring of 2008 Karl Backman had written songs for the new band and they started to rehearse. Jens Nordén had played with Lyxzén in pre-Refused straight edge hardcore band Step Forward (1987-1991) and since 1990 with Backman in punk band The Vectors.

In May 2008 someone posted a live song on YouTube. It got on Kerrang's playlist and had over 14,000 hits the first week. They performed at Storsjöyran and Umeå Punkfest in 2008. In 2009 they performed at Way Out West Festival and released the self-titled debut album on Lyxzén's label Ny Våg.

USS Cyclops (AC-4)
USS ''Cyclops'' (AC-4) was the second of four colliers built for the United States Navy several years before World War I. Named after the Cyclops, a race of giants from Greek mythology, she was the second U.S. Naval vessel to bear the name. The loss of the ship and 306 crew and passengers without a trace some time after 4 March 1918 remains the single largest loss of life in the history of the United States Navy not directly involving combat. As the loss occurred during World War I, she was thought to have been captured or sunk by a German raider or submarine, because she was carrying of manganese ore used to produce munitions, but German authorities at the time, and subsequently, denied any knowledge of the vessel. In this article, ''Amolco'' was erroneously called ''Amalco''. The Naval History & Heritage Command has stated she "probably sank in an unexpected storm", but the cause of the ship's loss is not known. History ''Cyclops'' was launched on 7 May 1910, by William C ...

Southern Pacific Class AC-4
Southern Pacific Railroad's AC-4 (meaning Articulated Consolidation) class of steam locomotives was the first class of 4-8-8-2 cab forward locomotives. They were intended to improve on the railroad's MC (Mallet-Consolidation) class 2-8-8-2 locomotives with a larger firebox, hence, the four-wheel leading truck (instead of the two-wheel). The AC-4s were the first SP Mallets built for simple expansion. Baldwin Locomotive Works The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades t ... built them in August through October 1928 with a maximum cutoff of 70%, so tractive effort was rated at ; a few years later, limited cutoff was dropped and calculated tractive effort increased to . The AC-4s were removed from service starting in 1953, and all ten were scrapped by June 1955. References * ...

AC4 Tank
The AC4 (Australian Cruiser Tank Mk. 4) was a cruiser tank designed in Australia in World War II as the intended successor to the AC3 Thunderbolt. Like its predecessors the AC4 was to have a one piece cast hull and turret. The AC4's most important characteristic would be the use of a 17 pounder tank gun. History Reservations about the utility of the 25 pounder in the AC3, and the 25 pounder's limited ability to pierce armour led to experimentation with a 17 pounder mounted on an Australian cruiser. A turret was built and mounted on one of the earlier development vehicles to assess the vehicle's ability to mount the foremost Allied anti-tank gun of the day – the British 17 pounder (76 mm, 3 in). This was achieved by mounting two 25 pounder gun-howitzers which when fired together would significantly exceed the recoil of a 17 pounder. In this configuration the tank was tested on 2 November 1942. It fitted with a 17 pounder and after successful gunnery trials on 17 November ...

Utilization Categories
In electrical engineering utilization categories are defined by IEC standards and indicate the type of electrical load and duty cycle of the loads to ease selection of contactors and relays. Definition The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions. The characteristic of the load to be switched or controlled determines the requirements for the switchgear and its correct selection for the intended application. In particular, the stress on the switching path caused by current and voltage during switching on and off is of enormous importance. For example, the switch-on and switch-off current at resistance load corresponds to the continuous operating current, while, for example, squirrel cage motors consumes multiple of t ...

Dolby AC-4
Dolby AC-4 is an audio compression technology developed by Dolby Laboratories. Dolby AC-4 bitstreams can contain audio channels and/or audio objects. Dolby AC-4 has been adopted by the DVB project and standardized by the ETSI. History Its development started in late 2011 to create a high-quality audio format that had a certain resemblance to Dolby TrueHD destined for multiple uses, to be used in streaming services, future TV broadcasts, and mainly to replace the traditional Dolby AC-3, and in December 2014 Dolby Laboratories approved the sound format for commercial use. On March 10, 2015, the Advanced Television Systems Committee (ATSC) announced that Dolby AC-4 was one of the three standards proposed for the audio system of ATSC 3.0. On July 14, 2015, Dolby Laboratories announced that Sony Visual Products and Vizio would support Dolby AC-4. On April 14, 2016, Dolby Laboratories announced that Samsung would ship TVs with support for Dolby AC-4 in 2017. Technical details Dolby AC- ...
