Reading the book Perform or Else by Jon Mckenzie along with the social distancing, isolation, and all the ongoing challenging and forced experiences of the 2020-21 Covid-19 pandemic era, on one hand, and my interests in performance art and physicality, on the other hand, made me think how can I create a work that represents an image of the body, the concept of action, and the idea of togetherness which are all essential for performance art, and/or for any performance. All art disciplines combine theory and practice in order to depict the relationship between bodies, art, and education, and as history proves, theory is always intended to be put into practice. The theoretical and practical in this written thesis begins with its title This Is Not a Thesis; continues by furthering the idea of Perform or Else, asking instead Thesis or Else; and goes on to serve its purpose of being a theoretical concern, a narrative, a genre in and of itself, an exercise in authorship, and furthermore, function as a documentation of documentation of my art – performance – practice. The series of written pieces, performances (rejected proposals), and images (documents) compiled here are meant to create a space between authorship and performance art. This Is Not a Thesis demonstrates the rejection and acceptance of the same thing at the same time.

Unmanned Aircraft Systems (UAS) have grown in popularity due to their widespread potential applications, including efficient package delivery, monitoring, surveillance, search and rescue operations, agricultural uses, along with many others. As UAS become more integrated into our society and airspace, it is anticipated that the development and maintenance of a path planning collision-free system will become imperative, as the safety and efficiency of the airspace represents a priority. The dissertation defines this problem as the UAS Collision-free Path Planning Problem. The overall objective of the dissertation is to design an on-demand, efficient and scalable aerial highway path planning system for UAS. The dissertation explores two solutions to this problem. The first solution proposes a space-time algorithm that searches for shortest paths in a space-time graph. The solution maps the aerial traffic map to a space-time graph that is discretized on the inter-vehicle safety distance. This helps compute safe trajectories by design. The mechanism uses space-time edge pruning to maintain the dynamic availability of edges as vehicles move on a trajectory. Pruning edges is critical to protect active UAS from collisions and safety hazards. The dissertation compares the solution with another related work to evaluate improvements in delay, run time scalability, and admission success while observing up to 9000 flight requests in the network. The second solution to the path planning problem uses a batch planning algorithm. This is a new mechanism that processes a batch of flight requests with prioritization on the current slack time. This approach aims to improve the planning success ratio. The batch planning algorithm is compared with the space-time algorithm to ascertain improvements in admission ratio, delay ratio, and running time, in scenarios with up to 10000 flight requests. / Includes bibliography. / Dissertation (PhD)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection

The purpose of this study was to explore the artistic experience of music teaching artists in two contexts, performing and teaching. This study explored musical artistry through flow dimensions as an operational tool and phenomenology as an analytical lens on the four coordinates of musical experiences: time, space, play, and feeling. Through these processes, I sought to gain new insights into the experiences of teaching artists in ways that have not been previously explored. Using a newly modified flow state scale, interviews, and focus group meetings as data collection, the artistic experiences of teaching artists were represented through nine flow dimensions. Individual flow portraits were crafted to present nuances, complexity, and anecdotes about teaching artists’ experiences. The study found flow characteristics and conditions meaningful in representing the individual experiences. Each teaching artist described a complex interaction of self, subject, and others through themes of self-discovery, self-dialogues, and self-actualization. Findings revealed multiple relationships between flow dimensions and diverse perceptions of the experience of flow. These findings help to paint a broader picture of artistry and define the artistic experience as it pertains to teaching and performing. Multiple factors and new investigative questions arising from the study are discussed as well. In essence, this study brings a new critical perspective on music education by illuminating the role of a teaching artist and sharing artistic experiences as a positive and transformative tool for learning.

This dissertation focuses on three major advances on multiple-input multiple-output (MIMO) systems. The first studies and compares decoding algorithms for multi-layered space time coded (MLSTC) systems. These are single user systems that combine spatial multiplexing and transmit diversity. Each layer consists of a space time code. The detection algorithms are based on multi-user detection theory. We consider joint, interference nulling and cancellation, and spatial sequence estimation algorithms. As part of joint detection algorithms, the sphere decoder is studied and its complexity is evaluated over MIMO channels. The second part contributes to the field of space frequency time (SFT) coding for MIMO-OFDM systems. It proposes a full spatial and frequency diversity codes at much lower number of trellis states. The third part proposes and compares uplink scheduling algorithms for multiuser systems with spatial multiplexing. Several scheduling criteria are examined and compared. The capacity and error rate study of MLSTBC reveals the performance of the detection algorithms and their advantage over other open loop MIMO schemes. The results show that the nulling and cancellation operations limit the diversity of the system to the first detected layer in serial algorithms. For parallel algorithms, the diversity of the system is dominated by the performance after parallel nulling. Theoretically, parallel cancellation should provide full receive diversity per layer but error propagations as a result of cancellation prevent the system from reaching this goal. However, parallel cancellation provides some gains but it doesn't increase the diversity. On the other hand, joint detection provides full receive diversity per layer. It could be practically implemented with sphere decoding which has a cubic complexity at high SNR. The results of the SFT coding show the superiority of the IQ-SFT codes over other codes at the same number of sates. The IQ-SFT codes achieve full spatial and frequency diversity at much lower number of trellis states compared to conventional codes. For V-BLAST scheduling, we propose V-BLAST capacity maximizing scheduler and we show that scheduling based on optimal MIMO capacity doesn't work well for V-BLAST. The results also show that maximum minimum singularvalue (MaxMinSV) scheduling performs very close to the V-BLAST capacity maximizing scheduler since it takes into account both the channel power and the orthogonality of the channel. / Ph.
