Strategies for the development of Kaohsiung County¡¦s cultural life circles study

Huang, Chiung-Ying 26 July 2001 (has links)
That study is based on three main factors, including Kaohsiung County¡¦s geographic features, its historical evolution, and the background of its cultural resources. In this study, the cultural life of Kaohsiung County is divided into three major circles ¡X the Fengshan Circle, the Gangshan Circle, and the Chishan Circle, which contains two other special circles¡Xthe Hakka Circle and the Aboriginal Circle. A survey was conducted to thoroughly understand the abundance of daily cultural life resources and the future continuous development of the existing cultural resources within the circles. Based on the information gathered, strategies for the development of Kaohsiung County¡¦s cultural life circles have been formulated.

On C^1 Rigidity for Circle Maps with a Break Point

Mazzeo, Elio 17 December 2012 (has links)
The thesis consists of two main results. The first main result is a proof that C^1 rigidity holds for circle maps with a break point for almost all rotation numbers. The second main result is a proof that C^1 robust rigidity holds for circle maps in the fractional linear transformation (FLT) pair family. That is, for this family, C^1 rigidity holds for all irrational rotation numbers. The approach taken here of proving a more general theorem that C^1 rigidity holds for circle maps with a break point satisfying a `derivatives close condition', allows us to obtain both of our main results as corollaries of this more general theorem.

On The Hamiltonian Circle Actions And Symplectic Reduction

Demir, Ali Sait 01 January 2003 (has links) (PDF)
Given a symplectic manifold, it is of interest how Lie group actions, their orbit spaces look like and what are some topological requirements on the existence of such actions. In this thesis we present the work of Ono, giving some sufficient conditions for non-existence of circle actions on symplectic manifolds and work of Li, describing the fundamental groups of symplectic reductions of circle actions.

Molecular Tools for Biomarker Detection

Chen, Lei January 2017 (has links)
The advance of biological research promotes the emerging of new methods and solutions to answer the biological questions. This thesis describes several new molecular tools and their applications for the detection of genomic and proteomic information with extremely high sensitivity and specificity or simplify such detection procedures without compromising the performance. In paper I, we described a general method namely super RCA, for highly specific counting of single DNA molecules. Individual products of a range of molecular detection reactions are magnified to Giga-Dalton levels that are easily detected for counting one by one, using methods such as low-magnification microscopy, flow cytometry, or using a mobile phone camera. The sRCA-flow cytometry readout presents extremely high counting precision and the assay’s coefficient of variation can be as low as 0.5%. sRCA-flow cytometry readout can be applied to detect the tumor mutations down to 1/100,000 in the circulating tumor cell-free DNA. In paper II, we applied the super RCA method into the in situ sequencing protocol to enhance the amplified mRNA detection tags for better signal-to-noise ratios. The sRCA products co-localize with primary RCA products generated from the gene specific padlock probes and remain as a single individual object in during the sequencing step. The enhanced sRCA products is 100% brighter than regular RCA products and the detection efficiency at least doubled with preserved specificity using sRCA compared to standard RCA. In paper III, we described a highly specific and efficient molecular switch mechanism namely RCA reporter. The switch will initiate the rolling circle amplification only in the presence of correct target sequences. The RCA reporter mechanism can be applied to recognize single stranded DNA sequences, mRNA sequences and sequences embedded in the RCA products. In paper IV, we established the solid phase Proximity Ligation Assay against the SOX10 protein using poly clonal antibodies. Using this assay, we found elevated SOX10 in serum at high frequency among vitiligo and melanoma patients. While the healthy donors below the threshold.

Modelling image quality for automotive display technologies

Wolf, Dorothee Christine January 2014 (has links)
The aim of this thesis is to link perceived image quality to physical display parameters. This is done in the context of automotive displays. Specialities of automotive display applications like high ambient lighting conditions and the necessity to access information quickly are explained. A summary of readability models relevant to automotive applications is given and the difference between readability and perceived image quality is explained. The methodology chosen to investigate perceived image quality is the Image-Quality-Circle framework by Engeldrum (2000). Engeldrum states that observers form their image quality rating by weighting the visual attributes they perceive. Visual algorithms, which can be investigated via psychometric scaling, link visual attributes to the underlying physical image parameters which are typically measure by physical instruments. The visual attributes investigated in this thesis are perceived contrast, brightness, blackness and colourfulness. Perceived contrast, brightness and blackness are derived from display luminance via the DICOM just noticeable difference (JND) scale. Colourfulness is scaled based colour gamut in the CIE1931 chromaticity diagram. It was shown that image quality rating rises with growing perceived contrast; the limiting factors are glare and perceived blackness. In colourfulness scaling a linear relationship between colour gamut and colourfulness rating was demonstrated. Higher colourfulness can compensate lower brightness in perceived image quality.

“Sunken Monadnock”: a Composition for Flute, Clarinet, Bassoon, Violin, Violoncello, Electric Guitar, Piano, Percussion, Three Female Vocalists, and Computer

Harris, Joshua Kimball 12 1900 (has links)
Sunken Monadnock is a scripted combination of three modular musical surfaces. The word “surface” is borrowed from Morton Feldman, who compared the aural surface of music to the canvases of the action painters of the American Abstract Expressionists, and contrasted it with the work’s subject, or organizational structure. Composers’ transition toward a focus on surface through indeterminate compositional techniques, according to Feldman, parallels the development of modernist abstract art. “Sunken Monadnock: Composing with Visual Metaphors” is a companion critical essay that takes the surface/subject metaphor as a starting point for analyzing Sunken Monadnock.Other visual metaphors that inspired Sunken Monadnock, and are discussed in the essay, include Shakir Hassan Al Said’s mystical semiotics, Jasper Johns’s crosshatch prints, and Wassily Kandinsky’s theory of abstraction. The circle and spiral, especially, play influential roles in Sunken Monadnock as reflected by musical applications of repetition, rotation, compression/rarefaction, and endlessness. The void in the circle’s center also comes into play. The nature of the work’s formal counterpoint requires an innovative approach to the score, which consists of five sections, each of which reflects a different approach to the aural surface (i.e., to the traversal of time). The two outer sections are traditionally scored, but the three sections in the middle—labeled “Surfaces” are played simultaneously by three subsets of the ensemble. The piece is approximately 22 minutes long.

The impact of using technology through cooperative learning on learners’ performance on grade 11 circle geometry

January 2019 (has links)
Magister Educationis - MEd / Euclidean geometry was recently re-introduced as a compulsory topic in the Mathematics Curriculum for learners in the Further Education and Training (FET) band in 2012. The diagnostic analysis reports on the National Senior Certificate (NSC) Mathematics Paper 2 examinations since 2014 has repeatedly expressed concern of the poor performance of leaners in proof and reasoning items linked to circle geometry. Various efforts have been made to examine the composition of the curriculum to find ways of motivating learners in the study of circle geometry and enhancing their performance but not much has been realized. The use of technology or cooperative learning approaches for the teaching of geometry is beneficial for pedagogical purposes, particularly for improving learners’ performance in geometry. Hence, this study investigated the impact of using technology through cooperative learning on learners’ performance on grade circle 11 geometry. It was thus an attempt to focus on blending these two teaching methods with an emphasis on the use of technology. The research took place at a Khayelitsha school and the scope of technology was limited to using a mathematical computer programme called Heymath. This research was grounded on the cognitive level framework that is used by the Department of Basic Education (DBE) in the setting of National Senior examination mathematics papers, as well as the set of social constructivist views of mathematics teaching and learning. In the case of the latter, both social constructivism and cognitive constructivism views were considered and applied for the purposes of this study. Using a positivist paradigm, this convergent parallel mixed methods study employed a quasi-empirical design, where the control group consisted of a group 26 grade 11 learners who were comparable to the group of 27 grade learners that made up the experimental group.
