General Simonds Speaks: Canadian Battle Doctrine in Normandy

On the afternoon of 11 July 1944, a Canadian Corps HQ once again became operational on the soil of France. Lieutenant-General Guy Granville Simonds assumed responsibility for 8,000 yards of front in the Caen sector. There was little time or inclination to mark this event or link it with the memory of the vaunted Canadian Corps of World War 1 fame—there was too much to be done. Elements of the newly-arrived 2nd Canadian Infantry Division would take over part of the line and acquire some badly needed experience. Plans for the Corps’ role in Operation “Goodwood” had to be elaborated while Simonds met with his Divisional and Brigade commanders. The following documents are reproduced from the War Diaries of the 2nd Field Historical Section, July 1944 (National Archives of Canada RG24 Volume 17506). Major A.T, Sesia, who commanded the unit, tried to record Simonds’ words in the first extract, but settled on a summary of the General’s views in subsequent reports

View from the Street: Partnerships and Collaboration

Richard Simonds and Josh Reynolds are social workers in Houston. Richard is the Director of THRIVE Connection at Family Houston. Josh is the Director of United Way Care for Elders, an initiative of United Way of Greater Houston that is a collaborative of aging service providers. One avenue of our collaboration has been a program called Financial Coaching at Family Services of Greater Houston. In aggregate we have run the program since 2007 – Josh from 2007 until the end of 2010, and Richard since that time. Financial Coaching and the more traditional Financial Education have been a part of a suite of economic programs at Family Houston, which has included a car loan program for working parents with poor credit, a (healthy) alternative to a payday loan product, and employment services. Financial Coaching and Education are also part of a larger community collaborative, United Way THRIVE, which is a coalition of 20 organizations focused on family financial stability in everything from job training to a full-service credit union and tax preparation services. Financial Coaching is financial education personalized and stretched out over six months to a year or longer. It is a best practice program that helps clients set a budget, reduce debt, save for their goals, and accomplish amazing things like home ownership or launching a small business. Also, because every decision and every relationship in life can have a financial component, Financial Coaching has the potential to touch on aspects of counseling, case management, family reunification, and many other elements of family function/dysfunction. It is one of the most comprehensive and impactful programs either one of us has come across in over 17 years of management

Impact of Mars sand on dust on the design of space suits and life support equipment: A technology assessment

Space suits and life support equipment will come in intimate contact with Martian soil as aerosols, wind blown particles and material thrown up by men and equipment on the Martian surface. For purposes of this discussion the soil is assumed to consist of a mixture of cominuted feldspar, pyroxene, olivine, quartz, titanomagnetite and other anhydrous and hydrous iron bearing oxides, clay minerals, scapolite and water soluble chlorides and sulfates. The soil may have photoactivated surfaces that acts as a strong oxidizer with behavior similar to hydrogen peroxide. The existing data about the Mars soil suggests that the dust and sand will require designs analogous to those uses on equipment exposed to salty air and blowing sand and dust. The major design challenges are in developing high performance radiators which can be cleaned after each EVA without degradation, designing seals that are readily cleaned and possibly in selecting materials which will not be degraded by any strong oxidants in the soil. The magnitude of the dust filtration challenge needs careful evaluation in terms of the trade off between fine-particle dust filters with low pressure drop that are either physically large and heavy, like filter baghouses require frequent replacement of filter elements, of low volume high pressure thus power consumption approaches, or washable filters. In the latter, filter elements are cleaned with water, as could the outsides of the space suits in the airlock

Path selection system development and evaluation for a Martian roving vehicle

A path selection system evaluation test procedure has been developed to enhance the analysis capability of an existing digital computer simulation package. The procedure investigates the obstacle avoidance ability of a path selection system on a sequence of test terrains with and without random effects. Using the standard test procedure a proposed mid-range sensor system has been evaluated and recommendations directed at improving the performance of the system have been made. In addition, the initial development and evaluation of a short range sensor system has been undertaken

Assessment of the state of the art in life support environmental control for SEI

This paper defines the types of technology that would be used in a lunar base for environmental control and life support system and how it might relate to in situ materials utilization (ISMU) for the Space Exploration Initiative (SEI). There are three types of interaction between ISMU and the Environmental Control and Life Support System (ECLSS): (1) ISMU can reduce cost of water, oxygen, and possibly diluent gasses provided to ECLSS--a corollary to this fact is that the availability of indigenous resources can dramatically alter life support technology trade studies; (2) ISMU can use ECLSS waste systems as a source of reductant carbon and hydrogen; and (3) ECLSS and ISMU, as two chemical processing technologies used in spacecraft, can share technology, thereby increasing the impact of technology investments in either area

The effect of extreme temperatures on the elastic properties and fracture behavior of graphite/polyimide composites

The influence of elevated and cryogenic temperatures on the elastic moduli and fracture strengths of several C6000/PMR-15 and C6000/NR-15082 laminates was measured. Tests were conducted at -157 C, 24 C, and 316 C (-250 F, 75 F, and 600 F). Both notched and unnotched laminates were tested. The average stress failure criterion was used to predict the fracture strength of quasi-isotropic notched laminates
