Problem solving

Problem solving consists of using generic or ad hoc methods, in an orderly manner, for finding solutions to problems. Some of the problem-solving techniques developed and used in artificial intelligence, computer science, engineering, mathematics, or medicine are related to mental problem-solving techniques studied in psychology.

Definition

The term problem-solving is used in many disciplines, sometimes with different perspectives, and often with different terminologies. For instance, it is a mental process in psychology and a computerized process in computer science. Problems can also be classified into two different types (ill-defined and well-defined) from which appropriate solutions are to be made. Ill-defined problems are those that do not have clear goals, solution paths, or expected solution. Well-defined problems have specific goals, clearly defined solution paths, and clear expected solutions. These problems also allow for more initial planning than ill-defined problems. Being able to solve problems sometimes involves dealing with pragmatics (logic) and semantics (interpretation of the problem). The ability to understand what the goal of the problem is and what rules could be applied represent the key to solving the problem. Sometimes the problem requires some abstract thinking and coming up with a creative solution.

000 Emergency

Triple Zero (000) is the primary national emergency number in Australia. The Emergency Call Service is operated by Telstra as a condition of its telecommunications licence, and is intended only for use in life-threatening or time-critical emergencies. Other emergency numbers in Australia are 112 for GSM mobile and satellite phones, which is answered by a Triple Zero (000) operator and 106 for TDD textphones. Triple Zero (000) was also the emergency number in Denmark and Finland until the introduction of the 112 number in 1993 and in Norway until 1986, when the emergency numbers diverted to 001 for fire brigade, 002 for police and 003 for ambulance. Those numbers changed in 1994 to 110, 112 and 113 respectively.

For calls to the State Emergency Service the Australia wide number 132 500 can be used (except for in the Northern Territory). This number should only be used for non–life-threatening situations.

History

Prior to 1969, Australia did not have a national number for emergency services; the police, fire and ambulance services possessed many phone numbers, one for each local unit. In 1961, the office of the Postmaster General (PMG) introduced the Triple Zero (000) number in major population centres and near the end of the 1980s extended its coverage to nationwide. The number Triple Zero (000) was chosen for several reasons: technically, it suited the dialling system for the most remote automatic exchanges, particularly outback Queensland. These communities used the digit 0 to select an automatic trunk line to a centre. In the most remote communities, two 0s had to be used to reach a main centre; thus dialling 0+0, plus another 0 would call (at least) an operator. Zero is closest to the finger stall on Australian rotary dial phones, so it was easy to dial in darkness.

Petersen Events Center

The Petersen Events Center (more commonly known as "The Pete") is a 12,508-seat multi-purpose arena on the campus of the University of Pittsburgh in the Oakland neighborhood of Pittsburgh, Pennsylvania. It hosts the men's and women's Pitt Panthers basketball teams. The arena is named for philanthropists John Petersen and his wife Gertrude, who donated $10 million ($13.7 million in 2016 dollars) for its construction. John Petersen, a Pitt alumnus, is a native of nearby Erie, Pennsylvania and is the retired President and CEO of Erie Insurance Group. The Petersen Events Center was winner of the 2003 Innovative Architecture & Design Honor Award from Recreation Management magazine.

History

The arena opened in 2002 on part of the former site of Pitt Stadium, which housed the university's football team from 1925–1999. The Pitt men's and women's basketball programs make their home here, previously residing in Fitzgerald Field House. The new building, due to its larger capacity, also meant that Pitt no longer had to play certain games or hold graduation ceremonies at the Civic Arena.
