RISTornado Composite Charts for the Canadian Prairies
Publisher: American Meteorological Society
Abstract: Composite charts of tornado situations are presented for the surface, 850-, 700-, 500-, and 200-mb levels for Manitoba and Saskatchewan. These charts do not cover all possible situations but are only for the most common ...
Cyclic Triaxial Strength of Mine Tailings
Publisher: American Society of Civil Engineers
Abstract: The cyclic strength of sand deposits is influenced by a number of factors including density, grain size, previous loading history, in situ stresses, age, particle shape and structure. In the case of uncompacted tailings ...
Estimating the Hazard of Ice Accretion in Canada from Climatological Data
Publisher: American Meteorological Society
Abstract: Ice storms are a major hazard which must be considered in structural design in all parts of Canada. The frequencies of occurrence of freezing precipitation are used to obtain a simple index of this hazard. To obtain more ...
The Impact of Polar Stratospheric Clouds on the Heating Rates of the Winter Polar Stratosphere
Publisher: American Meteorological Society
Abstract: We have computed the perturbation to the infrared radiative heating rates of the lower stratosphere due to the occurrence of polar stratospheric clouds (PSCs) during the winter season in the Antarctic and Arctic regions. ...
Measurements of the Energy Fluxes Involved in the Energy Budget of a Snow Cover
Publisher: American Meteorological Society
Abstract: Measurements of the various energy components involved in an energy balance of a snow cover were made at the Elora Research Station, University of Guelph during the winter of 1976. A pressure sphere anemometer and a sonic ...
Alternate Path Method in Progressive Collapse Analysis: Variation of Dynamic and Nonlinear Load Increase Factors
Publisher: American Society of Civil Engineers
Abstract: In performing alternative path analyses for checking the potential of a structure to progressive collapse, most designers often choose static procedures, which tend to be simpler and less labor demanding. As progressive ...
Extreme-Value Statistics for Snowpack Water Equivalent in the Northeastern United States Using the Cooperative Observer Network
Publisher: American Meteorological Society
Abstract: A procedure is developed to estimate extreme-value statistics for snowpack water equivalent (SWE) using historical snow depth measurements at cooperative observer stations in the northeastern United States. The method ...
Kinetic Analysis and Treatment of Compost Leachate Using Data from a Plant-Scale Hybrid Anaerobic Reactor
Publisher: ASCE
Abstract: Compost leachate is one of the most strongly polluting wastewaters, which is found in significantly large amounts. The major objective of this research was to study the biological treatment of compost leachate in an ...

A Controllable Membrane-Type Humidifier for Fuel Cell Applications—Part II: Controller Design, Analysis and Implementation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A membrane-based gas humidification apparatus was employed to actively manage the amount of water vapor entrained in the reactant gas supplied to a fuel cell stack. The humidification system ...
