Collective Labour Agreement between the Public Utilities Commission of the City of St. Catharines and Local 556, The International Brotherhood of Electrical Workers, 1952

In 1952, Local 556 of The International Brotherhood of Electrical Workers negotiated a contract with The Public Utilities Commission of the City of St. Catharines. The contract was to be in effect from July 1952 to September 1953. The document is unsigned.

Generator Matrix Based Search for Extremal Self-Dual Binary Error-Correcting Codes

Self-dual doubly even linear binary error-correcting codes, often referred to as Type II codes, are codes closely related to many combinatorial structures such as 5-designs. Extremal codes are codes that have the largest possible minimum distance for a given length and dimension. The existence of an extremal (72,36,16) Type II code is still open. Previous results show that the automorphism group of a putative code C with the aforementioned properties has order 5 or dividing 24. In this work, we present a method and the results of an exhaustive search showing that such a code C cannot admit an automorphism group Z6. In addition, we present so far unpublished construction of the extended Golay code by P. Becker. We generalize the notion and provide example of another Type II code that can be obtained in this fashion. Consequently, we relate Becker's construction to the construction of binary Type II codes from codes over GF(2^r) via the Gray map.

Niagara Falls Bridge Commission Scrapbooks, 1941-1948, 1953-1963, 1965-1974

The Niagara Falls Bridge Commission was created by a joint resolution of the 1938 U.S. Congressional Third Session. The Extra Provincial Corporations Act of Ontario, Canada licenses the Niagara Falls Bridge Commission. Canada and the United States are equally represented on the Commission by an 8 member Board of Commissioners. Canadian commissioners are appointed by the Premier of Ontario. The three Niagara bridges are the Whirlpool Bridge, the Lewiston-Queenston Bridge and the Rainbow Bridge. Source:http://niagarafallsbridges.com/index.php3

Hydro Electric Commission of Niagara Falls Ontario Scrapbook, 1936-1939, 1943-1951

Sir Adam Beck ( a London, Ontario manufacturer, Mayor and Conservative member of the provincial legislature) was a champion of municipal and provincial power ownership. Beck become the “Power Minister” and chairman of the Hydro-Electric Power Commission of Ontario which was the world’s first publicly owned utility. In 1925 the first unit of the Hydro Electric Power Commission’s Queenston Chippawa hydro-electric development on the Niagara River went into service. The station was renamed in 1950 as “Sir Adam Beck #1”. This marked the 25th anniversary of Beck’s death. This is one of 2 generating stations in Niagara Falls. There is also Adam Beck Plant #2. The Niagara generating stations supply one quarter of all power used in New York State and Ontario.Ontario Hydro has two water tunnels which traverse the entire City of Niagara Falls from the Village of Chippawa in the South to the Sir Adam Beck Hydro Electric Generating Stations in the North. Also they are in the process of building the third tunnel. In addition, Ontario Hydro has a 13.6 km open canal which traverses the entire City of Niagara Falls.

Niagara Parks Commission School of Gardening Graduation Program, 1956

The Niagara Parks Commission School of Gardening was organized in 1935 in order to help fill the Commission’s need for skilled gardeners to maintain the extensive parkland owned by the Commission. In 1959 the School was renamed the Niagara Parks Commission School of Horticulture. The name changed again in 1990 to the Niagara Parks Botanical Gardens and School of Horticulture to better reflect the development of the program.

A Study of Ordered Gene Problems Featuring DNA Error Correction and DNA Fragment Assembly with a Variety of Heuristics, Genetic Algorithm Variations, and Dynamic Representations

Ordered gene problems are a very common classification of optimization problems. Because of their popularity countless algorithms have been developed in an attempt to find high quality solutions to the problems. It is also common to see many different types of problems reduced to ordered gene style problems as there are many popular heuristics and metaheuristics for them due to their popularity. Multiple ordered gene problems are studied, namely, the travelling salesman problem, bin packing problem, and graph colouring problem. In addition, two bioinformatics problems not traditionally seen as ordered gene problems are studied: DNA error correction and DNA fragment assembly. These problems are studied with multiple variations and combinations of heuristics and metaheuristics with two distinct types or representations. The majority of the algorithms are built around the Recentering- Restarting Genetic Algorithm. The algorithm variations were successful on all problems studied, and particularly for the two bioinformatics problems. For DNA Error Correction multiple cases were found with 100% of the codes being corrected. The algorithm variations were also able to beat all other state-of-the-art DNA Fragment Assemblers on 13 out of 16 benchmark problem instances.
