Abstract:
Abstract. A new algorithm, featuring overlapping domain decompositions, for the parallel construction of Delaunay and Voronoi tessellations is developed. Overlapping allows for the seamless stitching of the partial Delaunay tessellations constructed by individual processors. The algorithm is then modified, by the addition of stereographic projections, to handle the parallel construction of spherical Delaunay and Voronoi tessellations. The algorithms are then embedded into algorithms for the parallel construction of planar and spherical centroidal Voronoi tessellations that require multiple constructions of Delaunay tessellations. Computational tests are used to demonstrate the efficiency and scalability of the algorithms for spherical Delaunay and centroidal Voronoi tessellations. Compared to serial versions of the algorithm and to the STRIPACK-based approaches, the new parallel algorithm results in significant speedups for the construction of spherical centroidal Voronoi tessellations.

Abstract:
In order to improve the effect of ecological smart city construction, this paper analyzes the application of the ecological economic model based on parallel accumulation sorting and dynamic Internet of Things in the construction of ecological smart city. Moreover, this paper studies the core technology algorithm of information retrieval, proposes a parallel accumulation sorting algorithm, and combines the dynamic Internet of Things and ecological economics to construct an ecological smart city construction model. In addition, on the basis of constructing an ecological smart city, this paper combines the parallel accumulation sorting algorithm and the dynamic Internet of Things technology to analyze the construction effect of the ecological smart city. The experimental research results show that the ecological economic model based on parallel accumulation sorting and dynamic Internet of Things has a good application effect in the construction of ecological smart city.

Abstract. A new algorithm, featuring overlapping domain decompositions, for the parallel construction of Delaunay and Voronoi tessellations is developed. Overlapping allows for the seamless stitching of the partial pieces of the global Delaunay tessellations constructed by individual processors. The algorithm is then modified, by the addition of stereographic projections, to handle the parallel construction of spherical Delaunay and Voronoi tessellations. The algorithms are then embedded into algorithms for the parallel construction of planar and spherical centroidal Voronoi tessellations that require multiple constructions of Delaunay tessellations. This combination of overlapping domain decompositions with stereographic projections provides a unique algorithm for the construction of spherical meshes that can be used in climate simulations. Computational tests are used to demonstrate the efficiency and scalability of the algorithms for spherical Delaunay and centroidal Voronoi tessellations. Compared to serial versions of the algorithm and to STRIPACK-based approaches, the new parallel algorithm results in speedups for the construction of spherical centroidal Voronoi tessellations and spherical Delaunay triangulations.

Abstract:
The best method to construct a high quality KD tree is by using Surface Area Heuristic[1][4] (SAH). However, the computation involved in SAH is expensive. Wald and Havran[2] introduced a sequential algorithm of O(NlogN) complexity, which reached the lower bound of constructing a binary tree. In this paper, we will introduce a parallel SAH KD tree construction algorithm based on the O(NlogN) sequential algorithm. We proposed data structure for parallel constructing process which can minimize the communication among working threads, and a load balance strategy for evenly distributing work load. Our algorithm can achieve 4x speed up on 8-core CPUs architecture.

Abstract:
The usage of navigation meshes for path planning in games and otherdomains is a common approach. One type of navigation mesh that recently has beendeveloped is the Local Clearance Triangulation (LCT). The overall aim of the LCT isto construct a triangulation in such a way that a property called theLocal Clearancecan be used to calculate a path in a more efficient and cheap way. At the time ofwriting the thesis there only exists one solution that creates an LCT, this solution isonly using the CPU. Since the process of creating an LCT involves the insertion ofmany points and edge flips which only affects a local area it would be interesting toinvestigate the potential performance gain of using the GPU. The objective of the thesis is to develop a GPU version based on thecurrent CPU LCT solution and to investigate in which cases the proposed GPU al-gorithm performs better. A GPU version and a CPU version of the proposed algorithm has beendeveloped to measure the performance gain of using the GPU, there are no algorith-mic differences between these versions. To measure the performance of the algorithmtwo tests have been constructed, the first test is called the Object Insertion test andmeasures the time it takes to build an LCT using generated test maps. The sec-ond test is called the Internal test and measures the internal performance of thealgorithm. A comparison between the GPU algorithm with an LCT library called Triplanner was also done. The proposed algorithm performed better on larger maps when imple-mented on a GPU compared to a CPU implementation of the algorithm. The GPU performance compared to the Triplanner was faster in some of the larger maps. An algorithm that builds an LCT from scratch is presented. Theresults show that using the proposed algorithm on the GPU substantially increasesthe performance of the algorithm compared to when implementing it on a CPU.

Abstract:
The concept of a tree has been used in various areas of mathematics for over a century. In particular, trees appear to be one of the most fundamental notions in computer science. Sequential algorithms for trees are generally well studied. Unfortunately many of these sequential algorithms use methods which seem to be inherently sequential. One of the contributions of this thesis is the introduction of several parallel techniques for the construction of various types of trees and the presentation of new parallel tree construction algorithms using these methods. Along with the parallel tree construction techniques presented here, we develop techniques which have broader applications. We use the Parallel Random Access Machine as our model of computation. We consider two basic methods of constructing trees:tree expansion and tree synthesis. In the tree expansion method, we start with a single vertex and construct a tree by adding nodes of degree one and/or by subdividing edges. We use the parallel tree expansion technique to construct the tree representation for graphs in the family of graphs known as cographs. In the tree synthesis method, we start with a forest of single node subtrees and construct a tree by adding edges or (for rooted trees) by creating parent nodes for some roots of the trees in the forest. We present a family of parallel and sequential algorithms to construct various approximations to the Huffman tree. All these algorithms apply the tree synthesis method by constructing a tree in a level-by-level fashion. To support one of the algorithms in the family we develop a technique which we call the cascading sampling technique. One might suspect that the parallel tree synthesis method can be applied only to trees of polylogarithmic height, but this is not the case.We present a technique which we call the valley filling technique and develop its accelerated version called the accelerated valley filling technique. We present an application of this technique to an optimal parallel algorithm for construction of minimax trees.<br>Science, Faculty of<br>Computer Science, Department of<br>Graduate

Abstract:
Parallel optical interconnects (POI) have attracted a great deal of attention in the past two decades as the system bandwidth continues to increase. Optical interconnects are known to have more advantages than their electrical counterparts in many aspects such as crosstalk, bandwidth distance product, power consumption, and RC time delay. The parallelization of several optical links is also an effective method to increase the aggregate data rate while keeping the component count manageable and to reduce the unit cost of optics, electronics, and packaging at lower line rate.<br>Parallel optical transceiver modules running at several gigabits per second are commercially available nowadays. Parallel optical receivers are one of the key components of parallel interconnected systems. In this work, we describe how a low-power parallel CMOS preamplifier IC and a deskew IC have been designed and fabricated through the IBM 0.13mum CMOS technology. The performances of three different transimpedance amplifier (TIA) topologies are compared experimentally. The best of the three TIAs shows a differential gain of 56.2dBO, 2.6GHz bandwidth, and less than -16dBm sensitivity with a bit-error-rate (BER) less than 10-12. The TIA consumes 2.5mW of power from a 1.2V supply while the channel power is 22mW with a 400mV pp differential output swing.<br>A novel method of accurately measuring the crosstalk power penalty with an on-chip PRBS generator is proposed and its implementation is described. The use of an on-chip PRBS generator to drive the dummy channels eliminates the data pattern dependence between the aggressors and the victim. The inevitable channel skew associated with parallel channels can be removed by a phase-locked loop (PLL) based deskew method. We investigated the skew compensation range of this method theoretically and our experimental results confirm our conclusion.<br>Various practical design and test techniques such as photodiode modeling, AC coupling, low-pass filtering and continuous skew generation, and their implementations, are discussed and implemented in this thesis.

Abstract:
(CAP) are transforming activities across the UK construction sector. CAP offers potential in a wide range of applications, for example: remote collection of data for design; geofencing of plant operation; semi-autonomous extraction and movement of materials; offsite and robotic construction. However, this transformation presents a challenge to the sector. The introduction of CAP technology lacks a unified approach. Practice differs across construction sites and between clients. As a result, CAP deployment varies significantly across sites and information flow between organisations is slow. The industry is developing a strong understanding of the potential presented by CAP, with exciting examples of new technology being applied in practice. However, the community is concerned over the pace and practicality of implementing new methods, in context of the current approach to commissioning and delivering construction projects. Because there is no clear direction to encourage the use of CAP, the industry must bear all the risks of investing in new systems. These investments are made in an environment where there’s a lack of certainty about the capability of the technology, and a lack of clarity about the risks, liabilities and acceptability of its use. What does the Roadmap describe? The Roadmap has been developed collaboratively with over 75 organisations. Questionnaires and workshops identified the actions required to overcome technical, business and legislative challenges affecting successful delivery of the vision. The Roadmap brings these together in nine workstreams, each focusing on key areas identified by stakeholders. These workstreams would be delivered in parallel through industry-wide collaboration.

Abstract:
Although classification tables based on susceptibility to chloride ion permeability are recommended in AASHTO T 358, the classification levels with respect to durability parameters may or may not be adequate. Of interest for concrete pavement performance, this study verifies the recommended classification levels against standard durability testing such as corrosion, salt scaling, and freeze-thaw. The researchers conducted corrosion, salt scaling, and freeze-thaw durability tests in parallel with electrical surface resistivity testing to compare performance classifications for each method. Twenty-four mixture designs were evaluated. The designs vary in water-to-cementitious material ratio (0.4, 0.45, and 0.5 w/cm ratio), supplementary cementitious material type (100% ordinary Portland cement, 20% Class C fly ash, 40% Grade 100 slag cement, and 8% silica fume replacements), and air content (air entrained and non-air entrained). The results of the experimental study indicate that there is no clear relationship between concrete electrical conductivity and durability performance based on standard methods of testing. It may not be appropriate for the determination of durability performance of a concrete mixture for concrete pavement construction. However, the test method does present advantages, as mixtures of similar composition and design can yield the same results over time under standardized curing. Here, resistivity-time curves could be a useful tool as part of a quality control and quality assurance program to ensure consistency in concrete delivery during construction.

Abstract:
This paper reports common failure mechanisms of steel headed stud anchors (shear studs) in concrete-filled steel composite decks found in the literature comprised through an extensive database of push-out tests representing multiple shear stud configurations used in composite construction around the world. Monotonically and cyclically loaded push-out test specimens perpendicular or parallel steel deck, or in solid slabs, are included in the evaluation. Comparisons to experimental strengths are made with the steel headed stud anchor strength prediction methods from various international Codes and Standards along with other mechanics-based design provisions proposed in the literature. It was found that the prediction for concrete failure modes is often over-predicted, especially in deck perpendicular configurations. Two alternative design equations are presented within the context of the AISC Specification to address consideration for concrete related failures and are validated through comparisons both with push-out tests and composite beam tests found in the literature.

Abstract:
The Sagamore Parkway Bridge consists of twin parallel bridges over the Wabash River in Lafayette, IN. The old steel-truss eastbound bridge was demolished in November 2016 and replaced by a new seven-span concrete bridge. The new bridge consists of two end-bents (bent 1 and bent 8) and six interior piers (pier 2 to pier 7) that are founded on closed-ended and open-ended driven pipe piles, respectively. During bridge construction, one of the bridge piers (pier 7) and its foundation elements were selected for instrumentation for monitoring the long-term response of the bridge to dead and live loads. The main goals of the project were (1) to compare the design bridge loads (dead and live loads) with the actual measured loads and (2) to study the transfer of the superstructure loads to the foundation and the load distribution among the piles in the group. This report presents in detail the site investigation data, the instrumentation schemes used for load and settlement measurements, and the response of the bridge pier and its foundation to dead and live loads at different stages during and after bridge construction. The measurement results include the load-settlement curves of the bridge pier and the piles supporting it, the load transferred from the bridge pier to its foundation, the bearing capacity of the pile cap, the load eccentricity, and the distribution of loads within the pier’s cross section and among the individual piles in the group. The measured dead and live loads are compared with those estimated in bridge design.

Abstract:
The objective of this study is to analyze the interaction between trade and non-trade cooperation in some of the today's major regional initiatives, particularly those between developing and industrialized countries. The study suggests a framework to explore what the paper calls a "trade and cooperation nexus". The modalities of this nexus can take different forms. For instance, non-trade cooperation may be an integral part of a formal trade or integration agreement, or may take place independently of such an agreement, as an ex-ante, ex-post or parallel agreement. This paper analyzes the EU approach, which proposes an unusually tight trade and cooperation nexus based on a three-pillar approach uniting political, economic and trade cooperation under a single umbrella agreement. Theoretically this approach should be attractive, especially in North-South agreements, because the promise of linking free trade with cooperation programs could enhance the benefits of the former for both parties. However, while innovative, the nexus is challenging in its construction and delivery. The paper will explore EU efforts in this area in the broader context of what is happening in other North-South initiatives.

Abstract:
Intraspecies identification (DNA "fingerprinting") of pathogenic avian mycoplasmas is a powerful tool for epidemiological studies and monitoring strain identity. However the only widely method available for Mycoplasma gallisepticum (MG) and M. synoviae (MS)wasrandom amplified polymorphic DNA (RAPD). This project aimed to develop alternative and supplementary typing methods that will overcome the major constraints of RAPD, such as the need for isolation of the organism in pure culture and the lack of reproducibility intrinsic in the method. Our strategy focussed on recognition of molecular markers enabling identification of MG and MS vaccine strains and, by extension, pathogenic potential of field isolates. Our first aim was to develop PCR-based systems which will allow amplification of specific targeted genes directly from clinical material. For this purpose we evaluated the degree of intraspecies heterogeneity in genes encoding variable surface antigens uniquely found in MG all of which are putative pathogenicity factors. Phylogenic analysis of targeted sequences of selected genes (pvpA, gapA, mgc2, and lp) was employed to determine the relationship among MG strains.. This method, designated gene targeted sequencing (GTS), was successfully employed to identify strains and to establish epidemiologically-linked strain clusters. Diagnostic PCR tests were designed and validated for each of the target genes, allowing amplification of specific nucleotide sequences from clinical samples. An mgc2-PCR-RFLP test was designed for rapid differential diagnosis of MG vaccine strains in Israel. Addressing other project goals, we used transposon mutagenesis and in vivo and in vitro models for pathogenicity to correlated specific changes in target genes with biological properties that may impact the course of infection. An innovative method for specific detection and typing of MS strains was based on the hemagglutinin-encoding gene vlhA, uniquely found in this species. In parallel, we evaluated the application of amplified fragment length polymorphism (AFLP) in avian mycoplasmas. AFLP is a highly discriminatory method that scans the entire genome using infrequent restriction site PCR. As a first step the method was found to be highly correlated with other DNA typing methods for MG species and strain differentiation. The method is highly reproducible and relatively rapid, although it is necessary to isolate the strain to be tested. Both AFLP and GTS are readily to amenable to computer-assisted analysis of similarity and construction of a data-base resource. The availability of improved and diverse tools will help realize the full potential of molecular typing of avian mycoplasmas as an integral and essential part of mycoplasma control programs.
