A computer-aided design scheme for both man-made and natural runoff systems is presented. The model uses linear programming to solve Muskingum routing equations through a drainage system, and provides design information through post-optimality (sensitivity) analysis. With the objective of minimizing the peak outflow from the system and using hydrograph ordinates as the decision variables, the output of the linear programming analysis shows the extent that each flow ordinate at every node in the network influences the peak flow at some downstream location. This information can aid the user in speeding up the design process to arrive at an efficient design - i.e., one which either minimizes construction costs or reduces the potential risk of flood damage. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

<p>Despite the fact that the sequence of the human genome is now complete it has become clear that the elucidation of the transcriptome is more complicated than previously expected. There is mounting evidence for unexpected and previously underestimated phenomena such as alternative splicing in the transcriptome. As a result, the identification of novel transcripts arising from the genome continues. Furthermore, as the volume of transcript data grows it is becoming increasingly difficult to integrate expression information which is from different sources, is stored in disparate locations, and is described using differing terminologies. Determining the function of translated transcripts also remains a complex task. Information about the expression profile &ndash / the location and timing of transcript expression &ndash / provides evidence that can be used in understanding the role of the expressed transcript in the organ or tissue under study, or in developmental pathways or disease phenotype observed.<br /> <br /> In this dissertation I present novel computational approaches with direct biological applications to two distinct but increasingly important areas of research in gene expression research. The first addresses detection and characterisation of alternatively spliced transcripts. The second is the construction of an hierarchical controlled vocabulary for gene expression data and the annotation of expression libraries with controlled terms from the hierarchies. In the final chapter the biological questions that can be approached, and the discoveries that can be made using these systems are illustrated with a view to demonstrating how the application of informatics can both enable and accelerate biological insight into the human transcriptome.</p>

競爭性內源核糖核酸(ceRNA) 假設最近已成為生物訊息學研究中最熱門的話題之一。Cell 是在生物科學界上經常被引用的學術期刊，早前亦有一班學者在Cell 2011年同一期成功發佈四篇關於ceRNA 假設的學術文章。跟據有關ceRNA 假設的學術文章，大部份學者均以不同的個別例子成功驗證假定，可是，欠缺一個大規模的及全面性的分析。 / 在我兩年碩士的研究中，我引入了一個新的概念微核糖核酸及其目標對向聚類(MTB) 運用了ceRNA 的假設，還提出算法，成功從微核糖核酸與信使核糖核酸的相互數據中找出一系列的MTB' 還利用GENCODE 項目上大量的微核糖核酸及信使核糖核酸的表達數據去驗証MTB 的概念。一方面，我從大量的表達數據中成功推斷出微核糖核酸與信使核糖核酸之間的相反關連、信使核糖核酸之間的正面關運和微核糖核酸之間的正面關連;另一方面，這些關連進一步肯定ceRNA 假設的真實性。此外，我提出一個從大量基因組中找出基因功能分析的方法，並在大量的MTB 的基因組中找出重要的基因註解。最後，我提出另一個MTB 概念的應用一新算法來預測微核糖核酸與信使核糖核酸的相互影響。總括而吉， MTB 概念從複雜且混亂的微核糖核酸與信使核糖核酸網絡中定義簡單且穩固的模姐，提供一個系統生物學分析微核糖核酸調節能力的方法。 / The competing Endogenous RNA (ceRNA) hypothesis has become one of the hottest topics in bioinformatics research recently. Four papers related to the ceRNA hypothesis were published simultaneously in Cell in 2011, a top journal in life sciences. For most papers related to the ceRNA hypothesis, the corresponding studies have successfully validated the hypothesis with different individual examples, without a large-scale and comprehensive analysis. / In my Master of Philosophy study, a novel concept, called mi-RNA Target Bicluster (MTB), is introduced to model the ceRNA hypothesis. The MTBs are identified computationally from validated and/or predicted miRNA-mRNA interaction pairs. The MTB models were tested with the mRNAs and miRNAs expression data from the GENCODE Project. Statistically significant miRNA-mRNA anti-correlation, mRNA-mRNA correlation and miRNA-miRNA correlation in expression data are found, verifying the correlation relations among mRNAs and miRNAs stated in the ceRNA hypothesis with large-scale data support. Moreover, a novel large-scale functional enrichment analysis is performed, and the mRNAs selected by the MTBs are found to be biologically relevant. Besides, some new target prediction algorithms are suggested, as another application of the MTBs, are suggested. Overall, the concept of MTB defines simple and robust modules from the complex and noisy miRNA-mRNA network, suggesting ways for system biology analyses in miRNA-mediated regulations. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Yip, Kit Sang Danny. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves [117]-126). / Electronic reproduction.
