Computational/experimental analysis of three low sonic boom configurations with design modifications

The Euler code, designated AIRPLANE, which uses an unstructured tetrahedral mesh was used to compute near-field sonic boom pressure signatures on three modern low sonic boom configurations: the Mach 2, Mach 3, and Haglund models. The TEAM code which uses a multi-zoned structured grid was used to calculate pressure signatures for the Mach 2 model. The computational pressure signatures for the Mach 2 and Mach 3 models are compared with recent experimental data. The computed pressure signatures were extracted at distances less than one body length below the configuration and extrapolated to the experimental distance. The Mach 2 model was found to have larger overpressures off-ground-track than on-ground-track in both computational and experimental results. The correlations with the experiment were acceptable where the signatures were not contaminated by instrumentation and model-support hardware. AIRPLANE was used to study selected modifications to improve the overpressures of the Mach 2 model

Thinking About LGBT Diversity in the Workplace

[Excerpt] Today, according to a May 13, 2011 report by the PEW Research Center, “a majority of Americans, 58%, now say that homosexuality should be accepted, rather than discouraged by society.” There are many reasons for this more inclusive shift in attitudes. Inclusion of sexual orientation, and increasingly gender identity, in workplace inclusion initiatives and diversity awareness dialogue is likely one. The workplace, driven by the pragmatic need for improved productivity, talent recruitment, and retention of a motivated workforce, has become a powerful environment for social change and learning

Keeping Members United in Contentious Times

[Excerpt] In contentious times, members often don’t see eye to eye, generating division and rivalries that undermine solidarity. Increasing membership diversity can lead to misunderstandings, which can escalate to disrespect. As a steward, you play a critical rol

Thinking About Five Strategies for Making Diversity Work

Greater diversity in the workplace introduces the possibility for increased misunderstanding and conflict at the same time as it holds out the promise of creativity and innovation. Workplace diversity change leaders have learned that making diversity work cannot be taken for granted. We cannot automatically assume that people will engage well with others across differences. Our history with bias, inequity and exclusion remains too much a part of how we understand one another. Making diversity work represents a mindset shift in the way people interact and engage. Organizations that are serious about creating inclusive work environments—where everyone feels welcomed, respected, and valued for who they are—recognize the importance of how people work together. Relationship building across differences needs to be developed and nurtured. Inclusive organizations focus on creating internal culture change to build people skills and promote shared expectations for mutual respect— an evolving endeavor. I’d like to add to the conversation by offering several observations for what this mindset shift might entail

MARKETING COLORADO POTATOES AS A VALUE-ADDED PRODUCT: A CASE STUDY

Potato producers in Colorado (and nationwide) have been facing a continued downward trend in potato commodity prices. In an attempt to increase demand for potatoes, these growers had Colorado State University (CSU) researchers perform a market study regarding the viability of marketing a value-added potato. A survey was performed which asked consumers to identify important potato characteristics, their willingness to pay for these characteristics, and what might prompt them to purchase more fresh or processed potatoes in the future. This paper discusses the results and recommendations that CSU made to the Colorado potato producers.Marketing,
