Toward a New Kinship Constellation
This thesis attempts to elaborate on my artwork during my graduate studies, while contextualizing it within the framework of the art world and the works of other artists. A main project during this time was to minimize the singular interpretation and framing of a fine art photographic print, while …

CubeSat Constellation Analysis for Data Relaying
… ground stations. It has been proposed to use a constellation of CubeSats to improve relay performance and increase the number of accesses between a CubeSat and ground stations. By using the spatial and temporal analysis features of STK, coupled with the STK/Matlab interface a robust tool was …

Architecture as a Constellation of Elements
… seeks to uncover making of architecture as a constellation or cluster of elements which assemble to form spaces humans inhabit. In doing so, it explores the architecture of incompleteness, where fragmented elements combine to form a dialogue with their adjacent elements, intensifying the …

Multi-Constellation GNSS Scintillation at Mid-Latitudes
… research is to challenge this belief. A multi-constellation and multi-frequency receiver, that tracks American, Russian, and European satellites, was used to monitor scintillation activity at the Virginia Tech Space Center. Analysis was performed on collected data from various days and compared …

Critical systems thinking and pluralism : a new constellation
This thesis explains theoretical issues concerned with paradigm incommensurability and the solutions offered by various critical systems writers. The problems of "imperialism" are outlined together with an analysis of the meta-theoretical views which purport to avoid imperialism. It is suggested …

Shape Up: Peak -Power Reduction via Constellation Shaping
… reduction as the number of channels and the constellation size increase. It also approaches the PAR characteristics of a single-carrier system (such as QAM or PAM) as the number of constellation points per channel increases. In addition, we present an O( N log2N) algorithm using a discrete …

Birth Order, Family Constellation, and College Music Performers
… which each self-reported his or her own family constellations (birth order, spacing, and sex of siblings) and his or her parents' family constellations where known. 492 subjects provided data on 1011 siblings, for 1503 offspring in the subjects' immediate families. The subjects provided data for …

CubeSat constellation implementation and management using differential drag
… include Planet, which is working to develop a constellation of over 100 Cube Satellites (CubeSats) to obtain global imagery data daily, and Astro Digital, which seeks to implement a constellation of multispectral imaging satellites to image the entire Earth every three to four days [1, 2]. …

Optimization of a Coded-Modulation System with Shaped Constellation
… transmit signals that are selected from a signal constellation with uniform probability. However, information-theoretic results suggest that performance may be improved by shaping the constellation such that lower-energy signals are selected more frequently than higher-energy signals. This …

Resource optimization algorithms for an automated coordinated CubeSat constellation
… a resource-constrained Earth-observing CubeSat constellation. The first algorithm is the Resource-Aware SmallSat Planner (RASP), which performs low-level planning of observation and communication activities for a single satellite while simultaneously keeping the satellite's onboard resources …

Satellite constellation design for mid-course ballistic missile intercept
… establish a conceptual approach to the design of constellations for satellite-based mid-course missile defense. The ballistic missile intercept problem leads to a new paradigm of coverage where interceptor "reachability" replaces line-of-sight coverage. Interceptors in this concept are limited in …

Developing Fixed-Bias Langmuir Probes for Multi-Point Constellation Deployments
<p>Since their initial development in the early 20th century, electrostatic Langmuir probes have proved invaluable in terrestrial and interplanetary ionospheric sounding applications. When deployed aboard rocket and satellite platforms, these probes yield high-cadence, in-situ measurements of key …

Continuity, constellation, and unworking: an exploration of language in Nietzsche
… language not as a unitary concept but as a constellation, a network of shifting thematic nodes, we find that language remains a chief interest throughout the Nietzschean corpus, but that its constitution is continually shifting as the texts emphasize changing nodal points. I then apply this …

Proliferated Low Earth Orbit (pLEO) Satellite Constellation Handover Cost Analysis
… of proliferated Low Earth orbit (pLEO) satellite constellation networks in which both the satellite and the user are mobile with respect to each other. As satellites travel in their obits, they move into and out of ground users’ views every few minutes [4], and mobile users can move into and out …
