Heat Demand Forecasting Models’ Development: Use of Data Mining Tools in SQL Server Analysis Services

This thesis introduces heat demand forecasting models which are generated by using data mining algorithms. The forecast spans one full day and this forecast can be used in regulating heat consumption of buildings. For training the data mining models, two years of heat consumption data from a case building and weather measurement data from Finnish Meteorological Institute are used. The thesis utilizes Microsoft SQL Server Analysis Services data mining tools in generating the data mining models and CRISP-DM process framework to implement the research. Results show that the built models can predict heat demand at best with mean average percentage errors of 3.8% for 24-h profile and 5.9% for full day. A deployment model for integrating the generated data mining models into an existing building energy management system is also discussed.

Improvement of Energy Efficiency in a Gold Mining Industry: Case Study of a Russian Gold Mining Company

The issue of energy efficiency is attracting more and more attention of academia, business and policy makers worldwide due to increasing environmental concerns, depletion of non-renewable energy resources and unstable energy prices. The significant importance of energy efficiency within gold mining industry is justified by considerable energy intensity of this industry as well as by the high share of energy costs in the total operational costs. In the context of increasing industrial energy consumption energy efficiency improvement may provide significant energy savings and reduction of CO2 emission that is highly important in order to contribute to the global goal of sustainability. The purpose of this research is to identify the ways of energy efficiency improvement relevant for a gold mining company. The study implements single holistic case study research strategy focused on a Russian gold mining company. The research involves comprehensive analysis of company’s energy performance including analysis of energy efficiency and energy management practices. This study provides following theoretical and managerial contributions. Firstly, it proposes a methodology for comparative analysis of energy performance of Russian and foreign gold mining companies. Secondly, this study provides comprehensive analysis of main energy efficiency challenges relevant for a Russian gold mining company. Finally, in order to overcome identified challenges this research conceives a guidance for a gold mining company for implementation of energy management system based on the ISO standard.

Investigating the potential of thecamoebians (testate amoebae) as bio-indicators of impact of oil sands mining operations on freshwater environments in Northeastern Alberta, Canada

Thecamoebian (testate amoeba) species diversity and assemblages in reclamation wetlands and lakes in northeastern Alberta respond to chemical and physical parameters associated with oil sands extraction. Ecosystems more impacted by OSPM (oil sands process-affected material) contain sparse, low-diversity populations dominated by centropyxid taxa and Arcella vulgaris. More abundant and diverse thecamoebian populations rich in difflugiid species characterize environments with lower OSPM concentrations. These shelled protists respond quickly to environmental change, allowing year-to-year variations in OSPM impact to be recorded. Their fossil record thus provides corporations with interests in the Athabasca Oil Sands with a potential means of measuring the progression of highlyimpacted aquatic environments to more natural wetlands. Development of this metric required investigation of controls on their fossil assemblage (e.g. seasonal variability, fossilization potential) and their biogeographic distribution, not only in the constructed lakes and wetlands on the oil sands leases, but also in natural environments across Alberta.

Ontario Tender Fruit Grower’s Marketing Board Fonds, 1960, 1967, 1969-1977, 1980-1981, 1987

The Ontario Tender Fruit Marketing Board operates under the Farm Producers Marketing Act. It covers all tender fruit farmers who produce either fresh or canned products. Today the board has over 500 grower-members. Tender fruit in the Niagara region includes: peaches, pears, plums, grapes and cherries. The fruits are used in a number of different ways, from jams and jellies to desserts, sauces and wine. Peaches were first harvested along the Niagara river in 1779. Peter Secord (Laura Secord’s uncle) is thought to be the first farmer to plant fruit trees when he took a land grant near Niagara in the mid 1780s. Since the beginnings of Secord’s farm, peaches, pears and plums have been grown in the Niagara region ever since. However, none of the original varities of peach trees remain today. Peaches were often used for more than eating by early settlers. The leaves and bark of the tree was used to make teas for conditions such as chronic bronchitis, coughs and gastritis. Cherries have been known to have anti-inflammatory and pain relieving properties. Like peaches and cherries, pears had many uses for the early pioneers. The wood was used to make furniture. The juice made excellent ciders and the leaves provided yellow dyes. Plums have been around for centuries, not only in the Niagara region, but throughout the world. They have appeared in pre-historic writings and were present for the first Thanksgiving in 1621. The grape industry in Ontario has also been around for centuries. It began in 1798 when land was granted to Major David Secord (brother-in-law to Laura Secord) slightly east of St. David’s, on what is Highway No. 8 today. Major Secord’s son James was given a part of the land in 1818 and in 1857 passed it onto Porter Adams. Adams is known to be the first person to plant grapes in Ontario1. Tender fruits are best grown in warm temperate climates. The Niagara fruit belt, stretching 65km from Hamilton to Niagara on the Lake, provides the climate necessary for this fruit production. This belt produces 90% of Ontario’s annual tender fruit crop. It is one of the largest fruit producing regions in all of Canada.

Glacial stratigraphy and micromorphology of the Pine Point Pb-­‐Zn mining district, Northwest Territories

This investigation aims to gain a better understanding of the glacial history of the Pine Point Mining district, Northwest Territories, by examining the sedimentological properties of the glacial sediments including, geochemical analysis, heavy mineral concentrate analysis, clast macro-­‐fabrics, pebble lithologies, and micromorphological investigation. Four till units were identified, and three were associated with identified erosional bedrock features and streamlined landforms in the area, indicating a minimum of three ice flow directions. Sedimentological properties suggest that these units were all Type-­B tectomict/mélange till, emplaced as part of a soft subglacial deformable bed. The lack of ice-­‐marginal advance and retreat sequences within the studied till, suggests the Middle Wisconsinan Laurentide Ice margin was likely north and west of the Pine Point area, as opposed to along the margin of the Canadian Shield and Western Sedimentary Basin where it has been suggested to have existed.
