Design evolution of medium gimbal scalable resistance dynamometer with user manual

Darrell Sparkes & Rob Pallard
This report documents the design, development and operation of a scalable flex plate resistance dynamometer for use in ship model resistance testing at OCRE/NRC St John’s replacing and improving on the traditional linear bearing resistance dynamometer. The report also contains the user manual detailing the setup of available operational modes for the dynamometer. There is also a proposal for future project development regarding an in-situ in line loading apparatus and adoption of the other facility...

Implementation, Verification and Validation of the Multi-Surface Failure Envelope for Ice in Explicit FEA (LS-DYNA) with Full Derivation of it’s Invariant Form

Jungyong Wang & Ahmed Derradji-Aouat
The multi-surface failure criterion/model for ice is implemented into an explicit finite element program called LS-DYNA (www.lstc.com). The implementation of the model equations was achieved via the development of a user routine for LS-DYNA. Since ice behavior depends on temperature, strain/load rate and loading direction (loading direction for the case of anisotropic ice), the traditional isotropic and temperature and rate independent failure criterion such as von-Mises and Mohr-Coulomb are not applicable. The multi-surface failure criterion...

Further experiments (1972) on the vegetative propagation of Chondrus crispus T4

P.F. Shacklock, D. Robson, I. Forsyth & A.C. Neish
Experiments were conducted on Chondrus crispus, strain T4, to provide further information on conditions needed to obtain increased carrageenan yields from culture tanks. At low densities (0.15 lb per ft2), high N-content plants grown without fertillizer increased their dry matter and carrageenan content more rapidly than at higher densities. An initial density of 0.6 lb per ft2 produced the largest amount of carrageenan over a one month period. Green plexiglass filters placed over tanks inhibited...

Surcharges dues au vent sur les bâtiments de faible hauteur

W. A. Dalgliesh
Des révisions importantes ont été apportées au Commentaire B du chapitre 4 du Supplément du Code national du bâtiment du Canada, édition de 1980, en ce qui a trait aux bâtiments de faible hauteur. Ces changements sont le résultat d'une série de mesures prises en vue de rationaliser le calcul des surcharges dues au vent. Ils sont fondés sur des essais en soufflerie à couche limite simulant l'action du vent sur un bâtiment et son...

Canadian energy storage roadmap: terms of reference

Adam Tuck, Qianpu Wang, Kourosh Malek, Yuri Grinburg & Farid Bensebaa
This project initiates, for the first time, a holistic approach to develop and maintain a multi-year (2016-2021) energy storage (ES) roadmap for Canada. It aims to understand market potential, roadblocks and actions required at the planning, procurement, rate treatment, interconnection, market, and regulations steps for adopting ES technologies in Canada by 2021. The project will result in fair and practical frameworks and mechanisms, published and updated annually, to support developing and integrating reliable and cost...

FM barrage jamming of a radar with Dicke Fix receiver

S.G. Jones
The expected performance of a radar equipped with Dicke Fix receiver is assessed in the presence of various types of FM barrage jamming. The minimum jamming-to-signal ratio for masking the echo signal is related to the received jamming power by a simple analytical expression, and the expected range performance of the radar is derived, assuming that most factors, other than range in the radar and beacon equations, are constants. The results of some radial flights...
