Topology-aware distributed graph processing for tightly-coupled clusters
No full textCloud applications have burgeoned over the last few years, but they are typically written for loosely-coupled clusters such as datacenters. In this thesis we investigate how one can run cloud applications in tightly-coupled clusters and network topologies, namely super-computers. Specifically, we look at a class of distributed machine learning systems called distributed graph processing systems, and run them on NCSA Blue Waters. Partitioning the graph is key to achieving performance in distributed graph processing systems. We present new topology-aware partitioning techniques that better exploit the structure of the network topologies in supercomputers. Compared to existing work, our new Restricted Oblivious and Grid Centroid partitioning approaches produce 25-33% improvement in makespan, along with a sizable reduction in network traffic. We also discuss optimizations such as smart network buffers that further amplify the improvement. To help operators select the best graph partitioning technique, we culminate our experimental results into a decision tree.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-05-01The student, Mayank Bhatt, accepted the attached license on 2018-04-23 at 17:13.The student, Mayank Bhatt, submitted this Thesis for approval on 2018-04-23 at 17:20.This Thesis was approved for publication on 2018-04-24 at 15:21.DSpace SAF Submission Ingestion Package generated from Vireo submission #12435 on 2018-08-31 at 17:21:19Made available in DSpace on 2018-09-04T20:36:52Z (GMT).

Revealing the Bonding Nature and Electronic Structure of Early-Transition-Metal Dihydrides
No full textMetal hydrides are potential candidates for applications in hydrogen-related technologies, such as energy storage, hydrogen compression, and hydrogen sensing, to name just a few. However, understanding the electronic structure and chemical environment of hydrogen within them remains a key challenge. This work presents a new analytical pathway to explore these aspects in technologically relevant systems using hard x-ray photoelectron spectroscopy (HAXPES) on thin films of two prototypical metal dihydrides: YH2−δ and TiH2−δ. By taking advantage of the tunability of synchrotron radiation, a nondestructive depth profile of the chemical states is obtained using core-level spectra. Combining experimental valence-band (VB) spectra collected at varying photon energies with theoretical insights from density functional theory (DFT) calculations, a description of the bonding nature and the role of d versus sp contributions to states near the Fermi energy are provided. Moreover, a reliable determination of the enthalpy of formation is proposed by using experimental values of the energy position of metal s-band features close to the Fermi energy in the HAXPES VB spectra
Single Crystal Growth of Halide Perovskites in Silica Gel
No full textHalide perovskites and its derivatives are well known for their potential applications in photovoltaics. However, for optimisation in devices, structure-property relations must be studied
systematically. As such, single crystals are champion forms of compounds that are able to
study the surfaces, crystallographically specific directions and bulk compositions of materials.
This Thesis explores a new synthesis method, called counter diffusion crystal growth (CDCG)
for single crystal growth of various halide perovskites.
The CDCG process and single crystals of the form ABX3
, A2BX6 and A3B2X9 have been
studied. The ability to understand the products of CDCG has been shown here for the first
time. Various structure-property relations for different perovskite and their related forms
show the utility of single crystals for intrinsic materials studies.
The organisation of the Thesis is as follows: Chapter 1 introduces the historical work
on CDCG as well as the research within the halide perovskite field, highlighting the scope
of this method for these materials. Chapter 2 details the experimental and analytical techniques used for experiments conducted for this Thesis. Chapter 3 explores the diffusion of
halide salts within silica gels and proposes a model for the prediction of CDCG experiments.
Chapters 4 and 5 used these models to synthesise a variety of complex perovskite single crystals. Surface, bulk and orientation studies uncovered crystallographic, chemical and
electronic structures. The crystals were studied with a range of analytical techniques, from
which new data analysis methods were introduced. Chapter 6 investigates the concept of
surface passivation on single crystals which is often misunderstood in the field. Chapter 7
summarises all findings

Bilingual interactions, linguistic choices, and the nature of bilingual grammar: Korean students in the United States
No full textThe goal of this dissertation is to make empirical and theoretical contributions to the understanding of the nature of the sociolinguistic grammar of bilingual language use. Specifically the main goal will test the claims of a theoretical methodology—that is, Optimality Theory (OT)-inspired—that imposes order on the vast array of sociolinguistic functions of code-switching and reach for generalizations, i.e., to what extent (or whether) Bhatt and Bolonyai’s (2011) model of OPTIMIZATION in code-switching generalizes over Korean-English bilingual data.
In the dissertation, the Korean-English bilingual data demonstrate the operation of the five constraints of Bhatt and Bolonyai (2011): FAITH, POWER, SOLIDARITY, PERSPECTIVE, and FACE. In other words, these universal constraints find empirical presence in the data analyzed in this dissertation. The Korean Heritage Students (KHS) data demonstrate that the interaction and optimal satisfaction of the five constraints yields a grammar that shows a complete domination-hierarchy among the following constraints, a desirable result, given OT: FAITH>>PERPSPECTIVE >>FACE>>SOLIDARITY>>POWER. Bhatt and Bolonyai (2011) had argued that the ideal in an OT-inspired account—where all constraints are potentially in conflict with each other—would be a grammar that resolves the conflict in a strict domination hierarchy. The Korean Early Study Abroaders (KESA) data also demonstrate the presence of a ranked grammar as follows; FAITH>> {PERSPECTIVE, FACE}>> POWER>> SOLIDARITY. The result of a preliminary data analysis of the KHS-KESA interactions indicates that the grammar of KHS acquiesces to KESA as follows, which could be an act of sociolinguistic accommodation; FAITH>> {PERSPECTIVE, FACE}>>POWER>>SOLIDARITY. This result, however, is counterintuitive considering the
stableness of the grammar of KHS compared to KESA’s. However, this is an interesting issue left for future research.
The research of the nature and design of a sociolinguistic grammar of bilingual interaction, that is, patterns of language use, contributes to the field of code-switching by shifting the theoretical focus of a study of bilinguals’ linguistic choices, i.e., code-switching, from monolingualism (or double monolingualism) to bilingualism—from monolingual grammars to bilingual grammars. This is not a new approach to bilingualism. Ferguson (1979) and Kachru (1987) already suggested in their early studies on multi-/bilingualism. In addition, the results of the research empirically validate the theoretical framework of OPTIMIZATION as a key construct of a sociolinguistic grammar (of bilingual language use); the Korean-English bilinguals data demonstrate the operations of five constraints and their interactions to build up a particular ranking for the optimal bilingual grammar of KHS and KESA. Finally, the domain of interaction across groups of quite similar (but not the same) bilinguals, KHS and KESA, shows that there might (must) be an interaction: that OT-grammars are mutable, in that domain. This is another research project for future that could bring an answer to the question of “How (and when/ where) do “processes” of linguistic accommodation, identification, and stance-taking interact with OPITMIZATION?”Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2017-12-01The student, Young-Sun Lee, accepted the attached license on 2015-11-17 at 15:43.The student, Young-Sun Lee, submitted this Dissertation for approval on 2015-11-17 at 16:24.This Dissertation was approved for publication on 2015-11-18 at 14:15.DSpace SAF Submission Ingestion Package generated from Vireo submission #8799 on 2016-03-02 at 14:05:50Made available in DSpace on 2016-03-02T20:23:30Z (GMT).
