Constituent Parts: Recent Portraiture in Canadian Military Art
Not common within the art historical record of the Canadian Military, the work of a number of visual artists participating in the Canadian Forces Artists Program demonstrates a keen and growing interest in portraiture. In this article, the work of Gertrude Kearns, Mary Kavanagh, and Erin Riley will be highlighted to illustrate the recent trend. Their work is contrasted with one another as well as with portraiture created by Canada’s war artists in the First and Second World Wars to bring to light the tensions of representation inherent in military portraiture. It will be shown that shifting perceptions found in the wider employment of portraiture and freedom given to participants in the Canadian Forces most recent official art program have encouraged depictions of members at all levels of the Canadian Forces
Analytical simulation of SPS system performance, volume 3, phase 3
The simulation model for the Solar Power Satellite spaceantenna and the associated system imperfections are described. Overall power transfer efficiency, the key performance issue, is discussed as a function of the system imperfections. Other system performance measures discussed include average power pattern, mean beam gain reduction, and pointing error
Automatic phase control in solar power satellite systems
Various approaches to the problem of generating, maintaining and distributing a coherent, reference phase signal over a large area are suggested, mathematically modeled and analyzed with respect to their ability to minimize: phase build-up, beam diffusion and beam steering phase jitter, cable length, and maximize power transfer efficiency. In addition, phase control configurations are suggested which alleviate the need for layout symmetry
How Community Engagement and the Power Nine Impact Health
The Blue Zones are five different places around the world where people are proven to live healthier and longer lives. In these places, they all share 9 unique habits that are attributed to helping achieve these healthier lives called the Power Nine. In Calloway County, a barrier survey was conducted by five different Murray State departments to see what stopped the residents from achieving their healthiest lives. Community engagement was found to be an important aspect of the Power Nine and was analyzed to see how it can impact one\u27s health
Social and Emotional Effects of Language-Based Learning Disabilities on Adolescents Approached Through Dance/Movement Therapy: A Literature Review
Over the past few years there has been a growth in research about the social and emotional effects of having a language-based learning disability. However, most of the interventions and assessments used with this population still primarily focus on the academic effects and do not always recognize the connection between the two. This literature review connects how identity development during adolescence in a school setting is impacted by the social and emotional effects of having a language-based learning disability. Individuals who experience learning difficulties often also experience internal and external academic criticism causing a decrease in self-esteem and an increase in anxiety and depressive symptoms. Dance/movement therapy can be used to enhance interventions and assessments in order to address cognitive, emotional, somatic, and social aspects of this population by allowing individuals to express internal states nonverbally, allowing individuals to feel seen, and creating safety and structure. This review also identifies the areas of potential growth within the current approaches such as understanding differences within the population, giving agency to the clients, and understanding clinician power dynamics. Dance/movement therapy strategies such as nonverbal communication, mindfulness, and the use of imagery can help to address some of these areas of potential growth. Further collaborative research among clients, families, clinicians, and teachers will be necessary in order to create assessments that are inclusive and use the strengths of the individual
Solar Power Satellite antenna phase control system hardware simulation, phase 4: Volume 1: Executive summary
The phase control system is described. Potential sources of phase error are identified and the performance leading to selection of the allowable phase error for each source is summarized. The pilot transmitter, the effects of ionospheric, the master slave returnable timing system (MSRTS), the SPS receiver, and the high power amplifier for dc to microwave conversion are considered separately. Design parameters of the pilot transmitter and spacetenna transponder are presented
Solar Power Satellite antenna phase control system hardware simulation, phase 4. Volume 2: Analytical simulation of SPS system performance
The pilot signal parameter optimization and power transponder analyses are presented. The SPS antenna phase control system is modeled and the hardware simulation study described. Ionospheric and system phase error effects and the effects of high power amplifier phase and amplitude jitters are considered. Parameter optimization of the spread spectrum receiver, consisting of the carrier tracking loop and the code tracking loop, is described
SPS phase control system performance via analytical simulation
A solar power satellite transmission system which incorporates automatic beam forming, steering, and phase control is discussed. The phase control concept centers around the notation of an active retrodirective phased array as a means of pointing the beam to the appropriate spot on Earth. The transmitting antenna (spacetenna) directs the high power beam so that it focuses on the ground-based receiving antenna (rectenna). A combination of analysis and computerized simulation was conducted to determine the far field performance of the reference distribution system, and the beam forming and microwave power generating systems
