Multigrid-reduction-in-time for Eddy Current problems

Parallel-in-time methods have shown success for reducing the simulation time of many time-dependent problems. Here, we consider applying the multigrid-reduction-in-time (MGRIT) algorithm to a voltage-driven eddy current model problem.Comment: Contribution from GAMM 2019 conferenc

Research Proposal: The Effects of Alcohol on the Social Aspects of High School Students

Although the legal drinking age is twenty-one, the age that a person begins to consume alcohol is decreasing. In a study in 1997, the average age of first alcohol use was 13.2 years old ( Maney, Higham-Gardill, & Mahoney, 2002). Drinking alcohol at a young age can lead to social problems and even delinquent behavior. It has been said that adolescent alcohol misuse has been shown to be part of a constellation of problem behaviors including delinquency and illicit drug use (Barnes, Welte, & Hoffman, 2002). Not only does it aid in future delinquency but also antisocial personality and health problems. Several studies have been done to discover the age and occurrences in which adolescents begin drinking and the possible consequences including but not limited to delinquent behavior, illicit drug use, sexual activity and longitudinal studies that project adult alcoholism. The main question in this particular research is to investigate if high school students who consume alcohol have a higher rate of social problems than those students who do not consume alcohol do. The reason for this research is the personal observance of adolescents who abuse alcohol, which resulted in problems with school and family life

Do You Know Your 50 States?

When information is forgotten, sometimes a visual cue can act as a spark to cue your memory into remembering the lost facts. In this study, the task at hand is recalling as many of the 50 United States as possible. Twenty undergraduate students were randomly assigned into two groups, where the first group’s task was free recall of the 50 states and the second group received a blank map of the states to test cued recall. This memory task may sound like an easy one but recalling the United States of America is tougher than participants imagined. However, there was no difference in the mean number of states recalled between the free recall condition and the cued recall condition

Are You Up To Date?

If an individual is up to date on current events, it makes it easier to carry on or even start a conversation with another individual who is also up to date. The researchers feel that individuals aged 40 and over are more up to date on current events than those ages 18- 25. In the current study, 46 participants; 26 participants aged 18-25 years old and 20 participants aged 40 years and older, recruited from the St. Charles area, took a ten question questionnaire on current events. The participants were divided by age and gender, so the study had a representative sample. Results showed t (44) =2.888, p=.003. The researchers had to reject the null hypothesi

On-Orbit Commissioning of High Performance Green Propulsion (HPGP) in the SkySat Constellation

In late 2012 Skybox Imaging selected HPGP technology for implementation on their second generation (propulsive) SkySat small Earth observation satellite platform. During 2013 ECAPS worked to design a complete, compact and ‘modular’ HPGP propulsion system; the first (protoflight) version of which was delivered in 2014. A total quantity of nineteen SkySat HPGP propulsion systems have been ordered thus far, and ‘assembly line’ manufacturing is ongoing at ECAPS – with multiple deliveries accomplished in 2015 & 2016, and continuing into 2017. The first five SkySat satellites with HPGP propulsion systems were launched during 2016 and an additional six SkySat satellites with HPGP systems are scheduled for launch in 2017 from Vandenberg AFB on Orbital ATK’s Minotaur-C. SkySat-3 was launched in June 2016 from the Satish Dhawan Space Centre on Antrix’s PSLV and SkySat-4 through SkySat-7 were launched in September 2016 from the Guiana Space Centre on Arianespace’s Vega. Each satellite’s HPGP system has been successfully commissioned and is now being operated in-orbit. This paper will begin by providing a brief introduction to HPGP technology; with a more in-depth description of the SkySat HPGP propulsion system design. A summary of the PSLV and Vega launch campaign fueling operations will also be provided, followed by the process and results of the post-launch propulsion system commissioning activities, and a performance overview of nominal on-orbit maneuvers executed to-date. Finally, a short update will be provided regarding the continued progress and improvement of HPGP technology, including maturation of the 5N & 22N HPGP thrusters to TRL-6 and the development of a new lower-cost ‘next generation’ 1N HPGP thruster
