Tackling Big Data Variety Using Metadata, Georgios Vranopoulos

School of Engineering, Computing and Mathematics Theses

The creation of new knowledge from manipulating and analysing existing knowledge is one of the primary objectives of any cognitive system. Out of the Big Data governing Vs, namely Volume, Velocity, Variety, Veracity, Validity, Volatility and Value, the first three are considered the primary ones. Most of the effort on Big Data research has been focussed upon Volume and Velocity, while Variety, “the ugly duckling” of Big Data, is often neglected and difficult to solve. A principal challenge with Variety is being able to understand and comprehend the data in gaining insight. Organisations have been investing in analytics relying on …

Life-Cycle Assessment Of Non-Domestic Building Stocks: A Meta-Analysis Of Current Modelling Methods, Julian Bischoff, Aidan Duffy

Articles

Building stock models (BSMs) are essential for simulating the contributions of regional and national building sectors to climate change under different policy scenarios, and for identifying pathways to climate change mitigation. To date, BSMs have focused on the operational life-cycle impacts of domestic dwellings; there has been less emphasis either on non-domestic buildings (NDBs) or full life-cycle analysis. This paper provides a first review of the theory and practice of NDB stock modelling which considers life-cycle energy, emissions and costs. A meta-analysis of the literature was undertaken involving a structured search of relevant articles in key scientific repositories. 98 in-scope …

Exploring The Concept Of The Digital Educator During Covid-19, Ana Schalk, Claire Mcavinia, Pauline Rooney

Journal Articles

In this paper, we explore academic identity, specifically the identity of the educator in higher education and academics’ conceptualisations of the digital educator. We suggest that the concept of a digital educator is not only about technology, tools and uses. The context for this exploration is academics’ participation in an online professional development module, Digital Education, and the “pivot online” (Weller, 2020a) during campus closures caused by the COVID-19 pandemic in 2020. Through qualitative research, we explored participants’ sense of teaching identity, whether they had or have a concept of being a digital educator and the extent to which these …

This handbook is developed for educators in entrepreneurship within universities and other higher education institutions. The aim of the handbook is to help underrepresented student groups within their courses. It is also useful for academics who want to develop entrepreneurship courses for specific minority groups. The notion of who underrepresented entrepreneurship students are may differ across institutions and across countries. At a global level, the OECD identifies six important cohorts: women, youth, seniors, the unemployed, immigrants, and people with disabilities (OECD, 2021)

A Media Archaeology Of Technologies Of Enchantment, Jane Hutchinson

School of Art, Design and Architecture Theses

This thesis explores how an understanding of an immaterial dimension of human experience was expressed and experienced in the context of nineteenth century engagement with science and technology. Drawing upon methods of media archaeology, it presents examples of visual technologies where apparatus and images representative of scientific and technological objectivity appear to have been appropriated and modified for the purpose of experiencing this dimension, an experience this thesis calls enchantment. The thesis suggests that some period specific behaviours associated with these visual technologies are sophisticated and subtle mechanisms that contribute to the affective and cognitive experience of enchantment. The flickering …

Juggling A Devil-Stick: Hybrid Orbit Stabilization Using The Impulse Controlled Poincaré Map, Nilay Kant, Ranjan Mukherjee

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The control design for juggling a devil-stick between two symmetric configurations is proposed. Impulsive forces are applied to the devil-stick at the two configurations; and impulse of the force and its point of application are modeled as the control inputs. The dynamics of the devil-stick is described by a single return Poincaré map, and it is shown that the control objective of juggling can be achieved by stabilizing a hybrid orbit. The impulse controlled Poincaré map (ICPM) approach, recently proposed for stabilization of continuous-time orbits of underactuated systems, is extended to achieve asymptotic stabilization of the hybrid orbit. The applicability …

Feature Learning For Optimal Control With B-Spline Representations, Vinay Kenny, Sixiong You, Chaoying Pei, Ran Dai

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The paper develops a feature learning-based method to solve optimal control problems using B-splines to approximate the optimal solutions. The feature learning-based optimal control method can quickly generate near-optimal trajectories for general optimal control problems subject to system dynamics and constraints. The steps in the proposed method are as follows: Firstly, by representing the state and control variables with B-spline functions, the optimal control problem is converted into an approximate nonlinear programming (NLP) problem, where parameters of the B-splines are identified as features of the optimal solution. Secondly, for a specific problem with designated inputs, a dataset of the optimal …

Religiosity From Age 12 To 20: Stability, Change, And Bidirectional Effects Of Attendance, Prayer, And Salience, W. Justin Dyer, Sam A. Hardy, Michael Goodman

Faculty Publications

Religiosity is a protective factor for adolescents, though research has indicated religiosity declines across adolescence. However, little research has examined how various dimensions of religiosity may change across time. With yearly data from a sample of 489 participants, the current study examined rank-order and mean level changes in religiosity from early adolescence (12 years-old) into late adolescence/emerging adulthood (20 years-old). Three dimensions of religiosity were examined, public religious practices (religious service attendance), private religious practices (prayer), and religious salience. Using cross-lagged models, reciprocal relationships between these dimensions were examined. There was significant rank-order stability, though stability was highest for attendance. …

Improving Virtual Synchronous Generator Control In Microgrids Using Fuzzy Logic Control, Oroghene Oboreh-Snapps, Rui Bo, Buxin She, Fangxing Fran Li, Hantao Cui

Electrical and Computer Engineering Faculty Research & Creative Works

Virtual synchronous generators (VSG) are designed to mimic the inertia and damping characteristics of synchronous generators (SG), which can improve the frequency response of a microgrid. Unlike synchronous generators whose inertia and damping are restricted by the physical characteristics of the SG, VSG parameters can be more flexibly controlled to adapt to different disturbances. This paper therefore proposes a fuzzy logic controller designed to adaptively set the parameters of the VSG during a frequency event to ensure an improved frequency nadir and rate of change of frequency (ROCOF) response. The proposed control method is implemented and tested on the power …

Discrete And Integrated Solutions For Hybrid Pv Plants Without Momentary Cessation In Low Scr And High Penetration Pe Grids, Phani R.V. Marthi, Suman Debnath, Jiuping Pan, Mariesa Crow

Electrical and Computer Engineering Faculty Research & Creative Works

With the increased penetration of power electronic (PE) based loads and sources, advanced solutions may be required for the enhancement of grid stability in regions with low short circuit ratio (SCR) and high penetration PE grids. The requirement of advanced solutions arises from the gradual paradigm shift of the electric grid from the traditional electric machine dominant system to a high penetration of PE-based system. One of the major challenges with such systems in recent times is the momentary cessation during alternating current (ac) grid transmission faults. During momentary cessation, PE-based resources cease to operate, thus creating probable reliability challenges …

An Interleaved High Step-Up Dc-Dc Converter With Built-In Transformer-Based Voltage Multiplier For Dc Microgrid Applications, Ramin Rahimi, Saeed Habibi, Mehdi Ferdowsi, Pourya Shamsi

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes a high step-up DC-DC converter with a built-in transformer (BIT)-based voltage multiplier (VM) that is suitable for integrating low-voltage renewable energy sources into a DC microgrid. A three-winding BIT is combined with the switched-capacitor (SC) cells to extend the voltage gain and reduce the voltage stress on the switches. The current-falling rates of the diodes are controlled by the leakage inductances of the BIT, alleviating the reverse-recovery problem of the diodes. The operating modes and steady-state analysis are presented. Additionally, the validity of the proposed converter is confirmed by the simulation and experimental results of a 400 …

Two-Level Targeter Convergence Study For Collinear Libration Point Spacecraft Formations, Donna Jennings, Henry J. Pernicka

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Spacecraft formation flying has attracted an increasing amount attention over the past several decades including a growing interest in relative motion at the collinear lib ration points. This current work builds on previous efforts by further developing and characterizing a two-level targeting (TLT) algorithm used to determine relative motion at lib ration points by performing a convergence study. A parametric study was conducted to identify the sensitivity of the algorithm to a variety of inputs and constraints. The parametric study revealed that the two-level targeting algorithm convergence properties significantly improve when using a higher order initialization estimate. The size of …

Fuel-Rich Hetero-/Homogeneous Combustion Of C3h8/O2/N2 Mixtures Over Rhodium, John Mantzaras, Ran Sui, Rolf Bombach

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The catalytic (heterogeneous) and gas-phase (homogeneous) combustion of C3H8/O2/N2 mixtures over rhodium was investigated experimentally and numerically at 5 bar and at fuel-rich equivalence ratios π = 2.0-3.5 relevant to propane Catalytic Partial Oxidation (CPO). In situ spatially-resolved Raman measurements of major gas-phase species concentrations and Planar Laser Induced Fluorescence (PLIF) of formaldehyde were applied in an optically accessible channel-flow reactor to monitor the catalytic and gas-phase processes, respectively, while accompanying 2D simulations were carried out with detailed hetero-/homogeneous chemical reaction mechanisms. Due to the high gas-phase reactivity of propane, homogeneous chemistry could not be ignored over most of the …

Direct Numerical Simulation Of Acoustic Disturbances In A Hypersonic Two-Dimensional Nozzle Configuration, Nathaniel Hildebrand, Meelan M. Choudhari, Cole P. Deegan, Junji Huang, Lian Duan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Direct numerical simulations (DNS) are performed to study acoustic radiation in a quasi-two-dimensional nozzle with two independents spatially evolving turbulent boundary layers with an edge Mach number of 6. The emphasis of this work is to compare the radiated pressure fluctuations in a geometrically confined environment with those radiated from a single wall in an unconfined setting. The boundary-layer profile of the rms pressure fluctuation scaled by the mean shear stress at the wall is found to be in good agreement with prior flat-plate calculations at similar conditions. However, the normalized rms pressure fluctuation within the freestream p region is …

Unstacking The Matryoshka Nesting Doll: A Self-Study Of Playful Language Instruction For Adult Second Language Learners, Marine Pepanyan

Dissertations and Theses @ UNI

In the recent three decades teaching second language (L2) vocabulary has expanded from sentence-level morphosyntactic features and pragmatics to the promotion and advancement of Communicative Language Teaching (CLT). Nevertheless, the L2 instructors are constantly seeking alternative strategies for vocabulary teaching and assessment due to a superficial level of vocabulary memorization and lack of student engagement. As an instructor-practitioner, I undertook a self-study of the process of implementing Playful Language Instruction (PLI) of L2 vocabulary in an Intensive English Program. In this self-study I combined conceptual lenses of theories of play, CLT, and the Adult Learning Theory to examine how playful …
