  • Factors Affecting Axial and Lateral Load Transfer of Hollow Fibre-Reinforced Polymer Piles In Soft Clay

    Resource Type:
    Report
    Creator:
    Lowry, Kelly
    Abstract:
    The growing interest in the long-term performance of pile foundations and their ability to resist the negative effects of water exposure and aggressive soils has led to considering non-corrosive materials such as fibre-reinforced polymer (FRP). The most common applications are light-bearing structures in waterfront environments, while applications for larger structures have not been widely accepted in industry due to the lack of long-term records and design guidelines available. Previous research has primarily focused on the load transfer of concrete-filled FRP tubes—making it difficult to quantify the performance of FRP as a piling material on its own. In this study, a numerical model using the finite element method was developed to simulate small-scale load tests of hollow carbon-fibre reinforced polymer (CFRP) and glass-fibre reinforced polymer (GFRP) piles in soft clay. Verification of the model was attained using results from axial and lateral load tests on small-scale hollow CFRP and GFRP piles and pile-soil interaction was modelled using experimental data from interface shear tests conducted at Carleton University. A parametric analysis was performed to investigate and determine the key factors that influence the axial and lateral load response of hollow FRP piles. The findings of this research indicate that the number of FRP layers impacts loading behaviour significantly, while inner tube soil height has a reasonable influence on axial load response and fibre orientation has a minor effect under lateral load conditions.

  • Report on the State of Alternative Energy in the Arctic

    Resource Type:
    Report
    Creator:
    Keyte, Lawrence, Dufresne, Vincent, Mallett, Alexandra, Cherniak, David, and Schott, Stephan
    Abstract:
    This report provides a contemporary snapshot of domestic energy usage in Canada’s Arctic (spanning Yukon in the west to Nunatsiavut in the east) with a focus on how Northern jurisdictions meet their electricity and space heating needs. Specifically, the research team investigated the role of alternative energy options, including the governance, policies and financial analysis of these sectors. The team also examined the emerging field of energy conservation and efficiency measures, which have featured prominently in recent years. The report also examines eight case studies from across Canada’s Arctic regions, which represent a cross-section of northern alternative energy and energy efficiency technologies, including both public and privately-driven projects. Each case study includes a project description, objectives and drivers, the role of policy, and a description of barriers, outcomes, success factors and lessons learned. The case studies are divided into five operational case studies, describing projects already constructed and producing renewable heat or power, or reducing demand-side energy loss, and three forward-looking case studies, representing projects still under active development. The report concludes with suggested areas for research and policy recommendations regarding energy system planning, financial policy, and education, engagement and collaboration, in the Canadian Arctic context.

  • NAT Traversal in Peer-to-Peer Architecture

    Resource Type:

    Abstract:
    Peer-to-peer networks are well known for file sharing between multiple computers. They establish virtual tunnels between computers to transfer data, but NATs makes it harder. A NAT, Network Address Translation, is a process which transforms private IP addresses, such as 192.168.2.1, into public addresses, such as 203.0.113.40. The idea is that multiple private addresses can hide behind a single public address and thus virtually enlarge the number of allocable public IP addresses. When an application in the local network establishes a connection to Internet, the packet passes through the NAT which adjusts the IP header and maps an external port to the computer which sent the request. When packets are received from the Internet by the NAT, they are forwarded to the internal host which is mapped to the port on which the packet was received, or dropped if no mapping exists. In this paper, we will introduce you to NAT and P2P, we will discuss the numerous ways NATs use to translate private IP addresses into public ones, we will discuss known techniques used to fix the problem and we will also present how popular peer-to-peer programs bypass NATs. This paper is written so anybody with a reasonable knowledge of networking would grasp the essentials. It is important to keep in mind that the traversal methods presented in this document work for UDP and TCP and require no manual configuration of the Network Address Translator itself.

  • Information Management in the Canadian Federal Government: Principles, Practices and the Role of Information Professionals

    Resource Type:
    Report

    Stricker, Ulla de and Jordan, Isla
    Abstract:
    Information management (IM) in the Canadian public sector is a complex area involving many professions such as librarians, archivists, records managers and information technology professionals. This exploratory study looks at the literature and experiential (qualitative) evidence from IM professionals in order to paint a picture of information management principles and practice in the Canadian federal government. Personal interviews were conducted with 20 librarians, information managers, records managers and other information professionals. Responses indicated that although the public sector has made tremendous strides in IM, there is often a gap between IM policy and practice as shown by inconsistencies and confusion in day to day operations compounded by the decimation of federal libraries (which are repositories of external as well as government information). The study also looks at roles of librarians and other IM professionals now and in the future. These professionals are well positioned to help close the gap between information policy and practice, moving forward toward more coordinated and integrated practices in information management as well as making information accessible and usable for their clients. Such functions aid the Canadian public sector in becoming a more effective knowledge organization.

    McKenna, Julie and Jordan, Isla
    Abstract:
    Accountability and data-informed decision-making are increasingly important for Canadian public institutions such as governments and universities. Canadian university libraries also appear to be placing more emphasis on evaluating and assessing their services and products. To discover more about the current assessment culture in Canadian university libraries, in 2007 Isla Jordan from Carleton University and Julie McKenna from the University of Regina conducted an online survey of services assessment practices in Canadian university libraries. The goals of this project were to gain a sense of assessment practices within the libraries and to provide a baseline for future comparisons and research into services assessment practice. Results showed that survey respondents were at different stages in assessing a variety of services and products. Respondents indicated that their libraries intended to increase their assessment activities in the future, particularly the LibQUAL survey.

    Abstract:
    Several studies including the Braidwood Commission report, the Report of the Standing Committee on Public Safety and National Security of the Conducted Energy Weapon, the report of the Commission for Public Complaints against the RCMP and other provincial reports and coroners’ recommendations have discussed the need for reliable uniform testing of Conducted Energy Weapons (CEWs) independent of the manufacturer. This version (3.0) adds an appendix which describes testing of the Taser 7 CEW. The CEW Test Procedure: - Establishes a methodology by which testing facilities and personnel across Canada will be able to test CEWs and determine whether they are operating within manufacturers’ specifications; - Defines data collection requirements so that data collected during the testing of any CEW in Canada may be used in forensic analysis of that weapon and may also be added to a central data base for future research and data mining programs.

    Abstract:
    Several studies have discussed the need for reliable uniform testing of Conducted Energy Weapons (CEWs) independent of the manufacturer. We propose a test proceedure that will enable organizations across Canada to test CEWs in a reliable, repeatable manner. This proceedure includes, but goes beyond, the one proposed by the manufacturer. Test results so obtained will also enable: 1. acceptance and regular validation of function of weapons in inventories of police service; 2. post incident testing to determine whether the weapon was functioning normally; 3. collection of weapons data across Canada to allow research on trends with age of weapon or other factors related to performance. The authors represent a group of subject matter experts who have been involved in research on or testing of CEWs.
