Circuit breaker

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by Overcurrent/overload or short circuit. Its basic function is to interrupt current flow after Protective relays detect faults condition. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

Nut Tree Airport

Nut Tree Airport (ICAO: KVCB, FAA LID: VCB, formerly O45) is a county-owned public-use airport located two nautical miles (3.7 km) northeast of the central business district of Vacaville, in Solano County, California, United States.

The airport is near the junction of Interstates 80 and 505. It is adjacent to the Nut Tree retail/commercial development, which replaced a historic US 40 highway stop from which both derive their name.

Facilities and aircraft

Nut Tree Airport covers an area of 262 acres (106 ha) at an elevation of 117 feet (36 m) above mean sea level. It has one runway designated 2/20 with an asphalt surface measuring 4,700 by 75 feet (1,433 x 23 m).

For the 12-month period ending March 3, 1995, the airport had 101,500 aircraft operations, an average of 278 per day: 98.5% general aviation and 1.5% air taxi. At that time there were 180 aircraft based at this airport: 90% single-engine, 8% multi-engine and 2% jet.

GeForce 600 series

The GeForce 600 Series is a family of graphics processing units developed by Nvidia, used in desktop and laptop PCs. It serves as the introduction for the Kepler architecture (GK-codenamed chips), named after the German mathematician, astronomer, and astrologer Johannes Kepler. GeForce 600 series cards were first released in 2012.

Overview

Where the goal of the previous architecture, Fermi, was to increase raw performance (particularly for compute and tessellation), Nvidia's goal with the Kepler architecture was to increase performance per watt, while still striving for overall performance increases. The primary way Nvidia achieved this goal was through the use of a unified clock. By abandoning the shader clock found in their previous GPU designs, efficiency is increased, even though it requires more cores to achieve similar levels of performance. This is not only because the cores are more power efficient (two Kepler cores using about 90% of the power of one Fermi core, according to Nvidia's numbers), but also because the reduction in clock speed delivers a 50% reduction in power consumption in that area.

Royal family

A royal family is the immediate family of a king or queen regnant, and sometimes his or her extended family. The term imperial family appropriately describes the family of an emperor or empress, while the terms ducal family, grand ducal family or princely family are more appropriate to describe the relatives of a reigning duke, grand duke, or prince. However, in common parlance members of any family which reigns by hereditary right are often referred to as royalty or "royals." It is also customary in some circles to refer to the extended relations of a deposed monarch and his or her descendants as a royal family. A dynasty is sometimes referred to as "the House of ...". As of July 2013, there are 26 active sovereign monarchies in the world who rule or reign over 43 countries in all.

Members of a royal family

A royal family typically includes the spouse of the reigning monarch, surviving spouses of a deceased monarch, the children, grandchildren, brothers, sisters, and paternal cousins of the reigning monarch, as well as their spouses. In some cases, royal family membership may extend to great grandchildren and more distant descendants of a monarch. In certain monarchies where voluntary abdication is the norm, such as the Netherlands, a royal family may also include one or more former monarchs. There is often a distinction between persons of the blood royal and those that marry into the royal family. In certain instances, such as in Canada, the royal family is defined by who holds the styles Majesty and Royal Highness. Under most systems, only persons in the first category are dynasts, that is, potential successors to the throne (unless the member of the latter category is also in line to the throne in their own right, a frequent occurrence in royal families which frequently intermarry). This is not always observed; some monarchies have operated by the principle of jure uxoris.
