This is a thesis about time. It is sited in Perth, Western Australia. Like other Australian states, Western Australia has a modern market system economy and enjoys, comparative to other countries with a market system economy, well developed social welfare and public education systems. The thesis shows how a set of fifteen people from Perth, Western Australia, who had all experienced a change in their domestic arrangements, understood time in the domestic sphere. Drawing upon their representations and constructions of their lives, and focusing on the concept of caring, this work demonstrates how temporal concepts can be utilised to control and limit choices these people have made in their lives.The evidence, collected through a series of open-ended and on-going discussions, is synthesized with theory, particularly the work of Barbara Adam. To Adam, an understanding of time involves appreciating the complexity of time. To gain such an understanding requires a research paradigm that allows this. Such an understanding requires stepping outside Cartesian dualistic thinking, including entrenched notions such as gendered time, and, an appreciation that differing temporal concepts exist and are utilised as mechanisms of control.

It is know that the LORD (Layered Orthogonal Lattice Detector) and the sphere decoding achieve performance equaling that of ML. However, both detectors have different disadvantage. When the transmit antenna number is greater than three antennas, it is difficult to apply the LORD. Therefore, we consider using the sphere decoding together with the LORD. The complexity of the sphere decoding highly depends on the initial radius. In this thesis, we intend to reduce the sphere decoding complexity by using LORD.

We are at a particular moment in history where new technologies are changing the way films are made, distributed, and screened, as well as how audiences interact with documentary texts and discourses. This dissertation project questions documentary's instrumentality in the public sphere in two parts. Using the response to Ken Burns' The War, as a point of departure, it first addresses the lacuna of theory and scholarship on documentary films, owed largely to its nascent arrival in academia as a dedicated field of study. Using the films and the public response around the films, I point out the problems with how documentary has been understood in both public and academic thought, with particular emphasis on truth claims, subjectivity narratives, and audience identification, as well as production techniques as rhetoric. Secondly the project takes two cases studies to examine these issues in documentary discourse and to exemplify the ways technology is changing documentary as we know it, one a reality television show focused on teenage mothers and the other Michael Moore's well known film Fahrenheit 9/11. Ultimately I argue that we are in a new era of documentary production that may be characterized by its interactivity between films, publics, and discourses. It is my hope that by combining my practical knowledge of documentary production for film and television with academic scholarship I will provide a valuable text for documentary theorists and rhetoricians alike. / text

In this Bachelor’s thesis the following question is answered: Does the inequality posed in the article Klyachko et al [2008] cover the real part of the Bloch surface of a 3D quantum system when used as in Kochen and Specker [1967]? The Klyachko inequality relies on using five measurements to show contextuality of a subset of states on the real part of the Bloch surface. These can now be used in several configurations as present in the Kochen-Specker contextuality proof, by simply rotating the measurements. We show here that these new inequalities will have subsets of violation that eventually cover the entire real part of the Bloch surface. This can be extended to show that all states of a spin 1 system are non-contextual, so that we have recovered a state-independent contextuality proof by using the Klyachko inequality several times. In the final part, an interpretation of this is given and also some recommendations for further research that should be done in the field.

Multiple-input multiple-output (MIMO) technique in communication system has been widely researched. Compared with single-input single-output (SISO) communication, its properties of higher throughput, more e?cient spectrum and usage make it one of the most significant technology in modern wireless communications. In MIMO system, sphere detection is the fundamental part. The purpose of traditional sphere detection is to achieve the maximum likelihood (ML) demodulation of the MIMO system. However, with the development of advanced forward error correction (FEC) techniques, such as the Convolutional code, Turbo code and LDPC code, the sphere detection algorithms that can provide soft information for the outer decoder attract more interests recently. Considering the computing complexity of generating the soft information, it is important to develop a high-speed VLSI architecture for MIMO detection. The first part of this thesis is about MIMO sphere detection algorithms. Two sphere detection algorithms are introduced. The depth first Schnorr-Euchner (SE) algorithm which generates the ML detection solution and the width first K-BEST algorithm which only generates the nearly-ML detection solution but more efficient in implementation are presented. Based on these algorithms, an improved nearly-ML algorithm with lower complexity and limited performance lose, compared with traditional K-BEST algorithms, is presented. The second part is focused on the hardware design. A 4*4 16-QAM MIMO detection system which can generate both soft information and hard decision solution is designed and implemented in FPGA. With the fully pipelined and parallel structure, it can achieve a throughput of 3.7 Gbps. In this part, the improved nearly-ML algorithm is implmented as a detector to generat both the hard output and candidate list. Then, a soft information calculation block is designed to succeed the detector and produce the log-likelihood ratio (LLR) values for every bit as the soft output.

Ionospheric disturbance electric fields of magnetospheric origin play an important role in determining the global morphology and dynamics of the ionosphere of the Earth. In this work, we present a number of numerical simulations of the transient electric fields in the middle and inner magnetosphere and the ionosphere equatorward of the auroral zone caused by idealized changes in the magnetospheric driving parameters. For these studies, we u se the Rice Convection Model (RCM), a large computer code of the magnetosphere-ionosphere coupling which consistently computes the electric fields, currents, and plasma densities in the magnetosphere and the electric field and currents in the ionosphere in the quasi-static slow-flow approximation. We made substantial upgrades to the code, which include a module computing realistic solar EDY-produced ionospheric conductances and a new potential solver. Our upgraded version of the RCM also includes a time - varying magnetospheric magnetic field and a self-consistently estimated auroral zone. We first discuss numerical problems encountered in modeling electrodynamics of convection with a time-varying magnetic field, realistic ionospheric conductances, and a self-consistent auroral zone, and our solutions to those difficulties. We then present a number of "computer experiments" with the new version of the RCM with idealized changes in the magnetospheric parameters such as sudden changes in the cross polar cap potential drop, magnetic field reconfiguration corresponding to the overall changes in the high-latitude convection, as well as rotations of the electric field on the polar cap boundary. Prompt penetration ionospheric electric fields simulated with the upgraded RCM are shown to be consistent with the previous simulations. The new simulations and their results are discussed in the context of (1) possible contribution to the variability of the ionospheric electric fields, and (2) role of time-varying magnetic field on the characteristic lifetimes of prompt penetration electric fields at subauroral, middle, and low latitudes.
