Carson Morrison
Carson F. Morrison, P.Eng. (1902–1993) was a university professor, innovative engineer, magazine editor, co-founder of the North American firm Morrison Hershfield, and president of a standards association. He was considered to be a touchstone for professional ethics and morality in engineering. He is remembered for his ideas and advice, knowledge and imagination. Early life and education Morrison was born on a farm in File Hills, in what is now Saskatchewan but then, in 1902, was called the Northwest Territories. He graduated from the University of Saskatchewan in Structural Engineering. He later taught there part-time and then continued on to McGill University where he received his Master of Science degree in Structural Engineering. His masters thesis (1927) is titled "The Effect of the Manner of Support and of Certain Details of Construction on the Secondary Stresses in a Roof Truss".

Radio Antenna
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductors ( elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction ( directional, or high-gain, or “beam” antennas). An antenna may include components not connecte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Staff Of The University Of Toronto
An academy ( Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, '' Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Hershfield
Charles Hershfield, B.Sc., M.A.Sc, F.E.I.C, P.Eng. (1910–1990) was widely recognized by the engineering community and known for his innovative structural engineering solutions, as a senior assistant engineer and lieutenant with the Department of National Defence (Canada), Department of National Defense, a professor at the University of Toronto, as co-founder of the North American firm Morrison Hershfield, and as a prolific author. He was a lifelong advocate of education and the engineering profession. Early life and education Hershfield' parents Aaron and Molly Hershfield left Teofipol, Ukraine in the mid-1890s for Manitoba, Canada in search of greater opportunities and in the hopes of starting a family. On December 24, 1910 their son Charles Hershfield was born. As a child and later in his teens, Hershfield's interests resided in music, baseball, carpentry, and mechanical engineering. He attended St. John's High School in Winnipeg, Manitoba, and even from a young age, highly va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heron Road Bridge
The Heron Road Workers Memorial Bridge (formerly the Heron Road Bridge) is a bridge in Ottawa, Ontario, Canada. It connects Baseline Road to Heron Road and allows east–west traffic to cross both the Rideau River and the Rideau Canal just south of Carleton University. The current bridge was finished in 1967, one year after a bridge collapse killed nine workers and injured over sixty others in the worst construction accident in both Ottawa and Ontario history. It was renamed in 2016 to commemorate the victims of that accident. Planning and early construction Ottawa Mayor Charlotte Whitton initially opposed the plans of Prime Minister John Diefenbaker to build the bridge to ease east–west traffic in the city. In 1961, Diefenbaker's government threatened to reduce the amount of federal grants to Ottawa by the cost of the bridge if the city did not agree to build it. After further negotiations, an agreement on building the bridge was signed by the municipal, provincial, and federa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building Codes
A building code (also building control or building regulations) is a set of rules that specify the standards for constructed objects such as buildings and non-building structures. Buildings must conform to the code to obtain planning permission, usually from a local council. The main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, interior designers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants, and others. Codes regulate the design and construction of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-Canada Line
The Mid-Canada Line (MCL), also known as the McGill Fence, was a line of radar stations running east–west across the middle of Canada, used to provide early warning of a Soviet bomber attack on North America. It was built to supplement the Pinetree Line, which was located farther south. The majority of Mid-Canada Line stations were used only briefly from the late 1950s to the mid-1960s, as the attack threat changed from bombers to ICBMs. As the MCL was closed down, the early warning role passed almost entirely to the newer and more capable DEW Line farther north. The MCL was based on the bistatic radar principle, using separated transmitters and receivers. An aircraft flying anywhere between the stations would reflect some of the transmitted signal towards the receiver, where it would mix with the signal travelling directly from the transmitter. The mixing of the two signals produces a pattern that is very easy to detect using simple electronics. As the transmitter is not pul ...

Pinetree Line
The Pinetree Line was a series of radar stations located across the northern United States and southern Canada at about the 50th parallel north, along with a number of other stations located on the Atlantic Ocean, Atlantic and Pacific coasts. Run by North American Aerospace Defense Command (NORAD) (after its creation), over half were staffed by United States Air Force personnel with the balance operated by the Royal Canadian Air Force. The line was the first coordinated system for early detection of a Soviet Union, Soviet bomber attack on North America, but before the early 1950s radar technology quickly became outdated and the line was in full operation only for a short time. History Plans for what would become the Pinetree Line were underway as early as 1946 within the Permanent Joint Board on Defense (PJBD), a Canadian-U.S. organization. However, the costs of running such a system in the post-war era was too high, and instead Canada concentrated on the areas around Ontari ...
