The SPAR thermal analyzer: Present and future

The SPAR thermal analyzer, a system of finite-element processors for performing steady-state and transient thermal analyses, is described. The processors communicate with each other through the SPAR random access data base. As each processor is executed, all pertinent source data is extracted from the data base and results are stored in the data base. Steady state temperature distributions are determined by a direct solution method for linear problems and a modified Newton-Raphson method for nonlinear problems. An explicit and several implicit methods are available for the solution of transient heat transfer problems. Finite element plotting capability is available for model checkout and verification

Elementary Mathematics and #BlackLivesMatter

The #BlackLivesMatter movement has opened up conversations in schools across the country about systemic racism, a “new” civil rights movement, and the treatment of children of color. In this article, a veteran elementary teacher uses the #BlackLivesMatter movement to help her students see the power of mathematics in their own lives, taking care to first connect with her school community so as not to incite trauma. Using an age-appropriate activity to investigate the feelings of anger felt by the Black community of Ferguson County, Missouri, shortly before the police murdered Michael Brown, we construct a conversation on what elementary mathematics learning looks like when framed around the guiding principles of #BlackLivesMatter. By utilizing and exploring the mathematics behind who gets into Peace Park, children connect various ways of recognizing inequity with mathematical observations, using mathematics as a tool to perceive and confront oppression

Elasticity and internal friction through the kilocycle range: reviwe and annotated bibliography

A review of techniques and fundamentals of Young\u27s modulus and internal friction measurements is presented. The effect of porosity on elasticity is extensively reviewed as are factors contributing to internal friction. An annotated bibliography of 377 entries covering elasticity and internal friction measurements through the kilocycle frequency range is included and accompanied by a keyword index
