Monte Carlo direct view factor and generalized radiative heat transfer programs

Computer programs find the direct view factor from one surface segment to another using the Monte carlo technique, and the radioactive-transfer coefficients between surface segments. An advantage of the programs is the great generality of problems treatable and rapidity of solution from problem conception to receipt of results

Memorialising Gallipoli: Manufacturing Memory at Anzac

The memorials of Gallipoli have not lost their power to move, confront and often even inspire their visitors. Their meanings are re-visited, even re-invented by each successive generation of Anzac pilgrim and, contrary to the simplistic mono-dimensional readings of some historians, the Peninsula’s commemorative landscape remains a site of fierce contestation. Pacifist and patriot, back packer and bereaved all interpret it differently. Moreover, the memorials of Gallipoli continue to alert us to different cultures of commemoration; Christian, secular and Islamic, Turkish, British, French and Australian

Set in Stone?:

Memorials to white explorers and pioneers long stood (virtually) unchallenged in the heart of Australia’s towns and cities. By occupying civic space, they served to legitimise narratives of conquest and dispossession, colonising minds in the same ways ‘settlers’ seized vast tracts of territory.  The focus of this article is a memorial raised to the memory of three white explorers, ‘murdered’ (it was claimed) by ‘treacherous natives’ on the north west frontier. It examines the ways that historians and the wider community took issue with this relic of the colonial past in one of the first encounters in Australia’s statue wars. The article explores the concept of ‘dialogical memorialisation’ examining the way that the meanings of racist memorials might be subverted and contested and argues that far from ‘erasing’ history attacks on such monuments constitute a reckoning with ‘difficult heritage’ and a painful and unresolved past. It addresses the question of whose voice in empowered in these debates, acknowledges the need for white, archival based history to respect and learn from Indigenous forms of knowledge and concludes that monuments expressing the racism of past generations can become platforms for truth telling and reconciliation

The Effect of Balance Training on Disruptive Behaviors in Children with Autism Spectrum Disorders

Objective The purpose of this study is to evaluate the effect of balance training on disruptive behaviors in children with Autism Spectrum Disorders (ASD). Methods Fourteen parents of children with ASD participated in this study. Data was collected using the Aberrant Behavior Checklist (ABC) distributed to various therapy centers around the Hattiesburg and Jackson areas. A secondary survey was included that collected demographic data and basic data on what therapies the children have been involved in. The ABC provided a measure of the incidence of disruptive behaviors exhibited by the children with ASD as evaluated by their parents. Three of the five subscales of the ABC were used including the irritability, stereotypy and hyperactivity subscales all of which were treated as separate dependent variables. The demographic data and list of therapies was used to investigate relationships between the therapies and disruptive behaviors and to split the participants into the experimental and control groups. The experimental group included those whose children had participated in balance training for more than a year and the control group included those whose children participated in balance training for less than a year. The data was analyzed using Hotelling’s Trace and Independent Samples t-scores. Results When all three dependent variables were analyzed collectively there was no statistically significant difference between the incidence of disruptive behaviors in the control and experimental groups p\u3e0.05. On a one-tailed independent samples t-test of the individual variables none achieved significance between the groups p\u3e0.05. When the data was grouped based on number of interventions disregarding type, the score on the irritability subscale just failed to reach significance with p=0.07. Conclusion None of the data was statistically significant even when analyzed for the effects of ABA and drug treatments which does not reflect the findings of past research. Limitations to this study include a small sample size, a quasi-experimental design, a lack of baseline measures, a lack of representation of patients without access to high quality therapeutic care, and a compromised control group which had to include individuals with less than a year of balance training. Future research with a larger sample and a stronger methodology is necessary to determine the effect of balance training on disruptive behavior in children with ASD. Further research may also need to investigate the link between number of therapies and disruptive behaviors

Politics, Paranoia, and Poly: The McCarthy-Era Red Scare and Its Impact on California State Polytechnic School, San Luis

Commie, Red, Pinko, Ruskie, bread-line potato-drinker; all of these are slurs made by Americans towards communists or communist sympathizers during the Cold War. Although communism is only a political theory designed by Karl Marx that predicts inevitable class warfare leading to publically owned land and shared labor, when this theory was applied in countries like Russia during the Cold War, it proved to be damaging to its citizens. The United States emerged from World War II as a dominating power, economically wealthy from wartime spending, and seemed to prosper in comparison to the U.S.S.R; which had suffered heavy losses during the war by serving as the main ground troops against Germany. As a result of these disparities, the U.S. took up a campaign focused on the “American way.” A majority of Americans held anti-communist sentiments due to the perceived immorality of the system. These prejudices influenced the university system. Encouraged by fear of political corruption and suspicion, liberally inclined individuals and organizations were identified as “political undesirables on campus” and either marginalized or sometimes removed from campuses. 1 “Communism.” oxforddictionaries.com.

Optimization Studies of a Compton Suppression Spectrometer Using Experimentally Validated Monte Carlo Simulations

Recent developments associated with room temperature semiconductor detectors and inorganic scintillators suggest that these detectors may be viable alternatives for the primary detector in a Compton Suppression Spectrometer (CSS). The room temperature operation of these detectors allows removal of a substantial amount of material from between primary and secondary detector and if properly designed and should afford substantially better suppression factors than can be achieved by germanium-based spectrometers. We have chosen to study the optimum properties of a CSS with a LaX3:Ce scintillator (where X is chloride or bromide) as the primary gamma ray detector. A Monte Carlo photon transport model is used to determine the optimum geometric properties of this spectrometer. To validate the assumptions and basic design of the Monte Carlo simulations, the energy distribution of a 137Cs point source is measured and simulated for two experimental systems. Comparison of the suppression factors for the measured and simulated data validates the model accuracy. A range of CSS physical parameters are studied to determine optimal detector geometry and to maximize the Compton suppression factor. These physical parameters and their optimum values are discussed

CONCEPT STATEMENT Due to the alarming prevalence of Chronic Traumatic Encephalopathy (CTE) and concussions among athletes, we aim to cease this stifling trend by developing an innovative helmet that protects the skull more thoroughly than previous models at an affordable cost. In addition to product development, we aim to update helmet standards, promote CTE prevention measures, and increase funding for research and treatment
