Using Simulation for Launch Team Training and Evaluation

This document describes some of the histor y and uses of simulation systems and processes for the training and evaluation of Launch Processing, Mission Control, and Mission Management teams. It documents some of the types of simulations that are used at Kennedy Space Center (KSC) today and that could be utilized (and possibly enhanced) for future launch vehicles. This article is intended to provide an initial baseline for further research into simulation for launch team training in the near future

Acoustic Effect of Holes on a Brass Disk

Recently it has become popular for music companies to manufacture cymbals with large symmetrically placed holes. The physics of how these perturbations effect the sound is unknown. This summer the effect of a single hole, and then multiple holes

Classification of Urban Forms and Their Relationship with Vegetation Cover in Cache County, Utah

As residential urban development increases in the western United States, few studies have shown how different urban forms influence vegetation cover. The two studies in this thesis examine how to define and measure urban form in order to understand the relationship between urban form characteristics and vegetation cover. In the first study, urban form was defined by using past methods of identifying and measuring urban sprawl. Past studies showed the most essential metrics that define residential urban form are building density, centrality, connectivity, land use mix, and parcel size. This study reviews these metrics and proposes revised unified definitions and measurement methods. It is recommended that consistent definitions and methods be used in further research of urban form. Cache County, Utah was used as a study area to apply these methods as a representative community of the western U.S. Residential parcels were measured for each metric. A K-means cluster analysis assign each parcel to one of 50 groups based on metric measurement similarities. The 10 most widely used groups contained 87% of the residential parcels in Cache County. These groups represented urban forms with distinct identifiable characteristics such as Agricultural residential, urban sprawl, historic plat patterns, and evolved versions each. The second study used the metrics and groups from the first study to check for correlations with vegetation cover. A normalized difference vegetation index ( NDVI) of aerial imagery of Cache County was used to classify land cover into three groups: dense vegetation, light vegetation, and no vegetation. Measurements of vegetation cover were extracted for each parcel and each urban form group. Total vegetation cover ( TVC) and dense vegetation cover (DVC) measured higher in urban areas than in the county as a whole. Agricultural residential groups had among the highest TVC, but had the lowest DVC. Non-agricultural residential groups had the highest DVC as a percentage of TVC with the exception of group 4 “Modern Suburban Sprawl” which had the lowest DVC as a percentage of TVC. Group 7 “Satellite Centers” had the highest TVC while group 3 “Dead End Semi-sprawl” had the lowest TVC. Both groups 3 and 7 had the highest DVC as a percentage of TVC. A correlation analysis revealed that TVC had stronger correlations than DVC with urban form metrics. Building density had the strongest correlation with TVC (r = -0.62, p= 0). Correlations with TVC were also found with Parcel size (r = -0.23, p

The Impact Of Classroom Management On New Teachers At A Newly Opened Elementary School

This dissertation in practice outlines an action research project that was designed in order to solve the research question of: What is the impact of Capturing Kids’ Hearts on improving the classroom management of beginning teachers and district new-hires in a new elementary school setting? This question was proposed on the idea that classroom management is something that many teachers will face as a challenge; especially beginning teachers. The Capturing Kids’ Hearts program was also determined to be beneficial as it contains attributes that would allow any teacher to obtain some useful information from the information. This action research project follows the process of action research which involves the following steps: identifying an area of focus, review existing data and literature, developing an action plan, implementing the plan, then analyze the new data (Mertler, 2014). Following these steps, one would reflect then repeat the process in order to find better solutions to a problem (Mertler, 2014). Staff members at a soon to be open elementary school were provided with an initial professional development training on the program. Throughout the year, teachers were observed and given feedback. Results indicated that utilizing the program had a positive impact on classroom management of beginning teachers. Teachers who were impacted were also shown to be more likely to stay in their position

Development of Constellation's Launch Control System

The paper focuses on the National Aeronautics and Space Administration (NASA) Constellation Program's Launch Control System (LCS) development effort at Kennedy Space Center (KSC). It provides a brief history of some preceding efforts to provide launch control and ground processing systems for other NASA programs, and some lessons learned from those experiences. It then provides high level descriptions of the LCS mission, objectives, organization, architecture, and progress. It discusses some of our development tenets, including our use of standards based design and use of off-the-shelf products whenever possible, incremental development cycles, and highly reliable, available, and supportable enterprise class system servers. It concludes with some new lessons learned and our plans for the future

Reed Canarygrass Germination at Five Seed Maturity Stages and Sixteen Seed Treatments

Reed canarygrass (Phalaris arundinacea) has long been recognized as adapted to wetlands and those subject to periodic flooding. In Utah, Wilson (1955) estimate that 40 percent of the valley bottom land is flooded at least part of the year. Much of this land is very dry late in the summer. Forages such as Alsike clover tolerate flooding and some salt but do not perform well under drouth. Work by Bolton (1946) indicated that flooding for 49 day did not cause serious permanent damage to Reed canarygrass. The author baa observed Reed canarygrass growing in a shallow reservoir which is flooded 90 days or more. Reed canarygrass is also one of the most drouth tolerant of the cool season grasses when grown on upland soils

The First Five Years of the Charlotte County Library, 1937-1942

On November 2, 1937, the Charlotte County Free Library opened its doors with five service goals to meet for the rural community. As the trailblazers of "David's Children," the name given to the nine other public libraries given by David K.E. Bruce to Southside Virginia communities, the librarians and trustees of the Charlotte County Free Library worked together to make the institution an overwhelming success. Over the next five years, despite a recession, Jim Crow politics, and World War Two, the library became a vital part of the rural farming community. How these goals were accomplished and the individuals behind these achievements will be investigated in this paper against the backdrop of the history of American public libraries
