International Student Support Groups: Learning From Experienced Group Members And Leaders, Nathan` Page, Mark Beecher, Derek Griner, Timothy B. Smith, Aaron Jackson, Klint Hobbs

Faculty Publications

Adjustment to college can be particularly difficult for international students. A multi-site qualitative study investigated the experiences of six group leaders and 10 group members who participated in seven different university counseling center international student support groups. Analyses of interview data using hermeneutic interpretation resulted in nine major themes and ten sub-themes organized into four sections: (1) Recruitment and group design, (2) Experiences of group members, (3) Experiences of group leaders, and (4) Additional considerations. College and university counseling centers can effectively work with international students by providing outreach and support groups.

The Value Relevance Of Taxes: International Evidence On The Proxy For Profitability Role Of Tax Surprise, Jon Kerr

Faculty Publications

Despite evidence that tax surprise is incrementally value relevant, the literature has done little to broaden the investigation beyond the United States or examine circumstances that affect informativeness. After extending to the international setting, I examine the impact of tax enforcement. I report strong results of greater value relevance when tax enforcement is high and that the value relevance of tax surprise is mostly contained within its interaction with tax enforcement. These findings highlight the importance of tax enforcement in determining the information content of tax surprise and suggest that extant and future discussions should be broadened to include it.

The Conclusion From One Million Tonnes Of Experience In Galvanizing Steel – Lmac Is Not A Primary Instigator Of Cracking, C Leighfield, Mn James

School of Engineering, Computing and Mathematics

In the period 2000–2006 occasional instances of serious service cracking in galvanized structural steelwork were detected. At the time it was suggested that the cracks had occurred during the galvanizing process, been covered up by the zinc coating and then opened up during service. Several significant European-wide research projects were initiated to identify and understand the mechanisms that control LMAC during hot dip galvanizing. However, experience in the UK has shown that the frequency of cracking of structural steel during galvanizing is very low, and that when it does occur it is almost invariably due to known factors that influence …

Y2O3 Optical Constants Between 5 Nm And 50 Nm, Joseph B. Muhlestein, Benjamin D. Smith, Margaret Miles, Stephanie M. Thomas, Anthony Willey, David D. Allred, R. Steven Turley

Faculty Publications

We report optical constants of e-beam evaporated yttrium oxide Y₂O₃ thin films as determined from angle-dependent reflectance measurements at wavelengths from 5 to 50 nm. Samples were measured using synchrotron radiation at the Advanced Light Source. The experimental reflectance data were fit to obtain values for the index of refraction and thin film roughness. We compare our computed constants with those of previous researchers and those computed using the independent atom approximation from the CXRO website. We found that the index of refraction near 36 nm is much lower than previous data from Tomiki as reported by …

From Ocean Sprawl To Blue-Green Infrastructure – A Uk Perspective On An Issue Of Global Significance, Ally J. Evans, Louise B. Firth, Stephen J. Hawkins, Alice E. Hall, Joseph E. Ironside, Richard C. Thompson, Pippa J. Moore

School of Biological and Marine Sciences

Artificial structures are proliferating in the marine environment, resulting in ‘ocean sprawl’. In light of the potential environmental impacts of this, such as habitat loss and alteration, it is becoming increasingly important to incorporate ecologically-sensitive design into artificial marine structures. The principles of eco-engineering and green infrastructure are embedded in urban planning practice for terrestrial and freshwater development projects. In marine planning, however, eco-engineering of blue-green infrastructure remains an emerging concept. This note provides a UK perspective on the progress towards uptake of eco-engineering approaches for enhancing biodiversity on artificial marine structures. We emphasise that, despite a clear ‘policy pull’ …

Three Decades Of On-Road Mobile Source Emissions Reductions In South Los Angeles, Gary A. Bishop

Fuel Efficiency Automobile Test Publications

In May of 2018, the University of Denver repeated on-road optical remote sensing measurements at two locations in Lynwood, CA. Lynwood area vehicle tailpipe emissions were first surveyed in 1989 and 1991 because the area suffered with a large number of carbon monoxide (CO) air quality violations. These new measurements allow for the estimation of fuel specific CO and total hydrocarbon (HC) emissions reductions, changes in the longevity of emission-control components, and the prevalence of high emitters in the current fleet.

Since 1989 CO emissions decreased approximately factors of 10 (120 ± 8 to 12.3 ± 0.2 gCO/kg of fuel) …

On Coding And Detection Techniques For Two-Dimensional Magnetic Recording, Mohammed Dikko Almustapha

School of Engineering, Computing and Mathematics Theses

The areal density growth of magnetic recording systems is fast approaching the superparamagnetic limit for conventional magnetic disks. This is due to the increasing demand for high data storage capacity. Two-dimensional Magnetic Recording (TDMR) is a new technology aimed at increasing the areal density of magnetic recording systems beyond the limit of current disk technology using conventional disk media. However, it relies on advanced coding and signal processing techniques to achieve areal density gains. Current state of the art signal processing for TDMR channel employed iterative decoding with Low Density Parity Check (LDPC) codes, coupled with 2D equalisers and full …

Smoothed Particle Hydrodynamics Modelling Of The Impact Of A Flat Plate Upon An Aerated Water Surface, Hassan Muhammad Sdiq

School of Engineering, Computing and Mathematics Theses

Smoothed Particle Hydrodynamics (SPH) is a particle-based method for solving Navier-Stokes and similar equations and is well-suited to problems where the computational domain becomes highly deformed. This study will describe in detail SPH simulations of various single- and multiphase flows with free surfaces and interactions with structures and solid surfaces. All 2D and 3D implementations have been compared with other numerical and experimental results. By adoption of multiphase and 3D models the computational requirements rise due to the increased number of particles. The fact that large numbers of particles are required in the simulations means that a parallelised version of …

The Lattice Boltzmann Method For Flows With Slip And No-Slip Boundaries, Seemaa Abdulsattar Mohammed

This thesis assesses and extends a modern method to study the physics of simple and complex flows by using the lattice Boltzmann method (LBM). With the moment-based boundary conditions, different problems with no-slip and slip boundaries are simulated. The moment method is based on the specification of the appropriate hydrodynamic moments of LBM. Throughout this thesis, distinct collision operators of D2Q9 LBM are presented and examined; the models include the Bhatnager-Gross-Krook (BGK), multiple relaxation time (MRT) and a special case of the last model which is two relaxation times (TRT-LBM). Simple numerical simulations are given and the LBM proved its …

An Evaluation Of Targeted Security Awareness For End Users, Najem Mahmoud Ahmmed Ahmmed

School of Engineering, Computing and Mathematics Theses

Users are frequently cited as being the weakest link in the information security chain. However, in many cases they are ill-positioned to follow good practice and make the necessary decisions. Part of the reason here is that even if security awareness, training and/or education have been provided, some of the key points may have been forgotten by the time that users find themselves facing security-related decisions. There are several scenarios in which users find themselves facing security-related decisions. However, while in such situations, many do not have an adequate understanding of security and do not receive the appropriate advice to …

The Agile Model-Driven Method, Klaus Mairon

School of Engineering, Computing and Mathematics Theses

Today the development of business applications is influenced by increased project complexity, shortened development cycles and high expectations in quality. Rising costs in the software development are an additional motivation to improve the productivity by the choice of a suitable development process. In the development of complex applications models are of great importance. Models reduce complexity by abstraction. Additionally, models offer the possibility to build different views onto an application. If models are sufficiently formal they are suitable for the automated transformation into source code. For this reason, an important acceleration and quality factor in the software development is attributed …

Advancing User Authentication And Access Management, Jeffery Crume

School of Engineering, Computing and Mathematics Theses

In order for online systems to transact business or exchange other sensitive information, there must be an environment where the parties involved can verify that the other is who they claim to be. Authentication mechanisms provide this verification process, thereby, improving confidence in the confidentiality and integrity of communications. However, attackers can exploit this trust if they are able to successfully impersonate a legitimate user and gain access to the system with all the rights and privileges of that user. One particularly difficult class of attacks of this sort involves an attacker inserting themselves between the end user and the …

Network Security Intelligence Centres For Information Security Incident Management, Natalia Miloslavskaya

School of Engineering, Computing and Mathematics Theses

Intensive IT development has led to qualitative changes in our living, which are driving current information security (IS) trends and require sophisticated structures and adequate approached to manage IS for different businesses. The wide range of threats is constantly growing in modern intranets; they have become not only numerous and diverse but more disruptive. In such circumstances, organizations realize that IS incidents’ timely detection and prevention in the future (what is more important) are not only possible but imperative. Any delay and only reactive actions to IS incidents put their assets under risk. A properly designed IS incident management system …

The Impact Of Firm Characteristics On Speed Of Adjustment To Target Leverage: A Uk Study, James Fitzgerald, J. Ryan

Articles

Responding to the need to investigate heterogeneity in the speed of adjustment (SOA) to target leverage in a manner that reflects the fractional nature of leverage, we estimate SOA across sub-samples of UK firms using the Dynamic Panel Fractional (DPF) estimator. Using firm characteristics to identify firms subject to varying costs of deviation from and adjustment to target leverage, we find significant evidence of heterogeneity in the speeds at which UK firms adjust to target leverage. Our results show that small, high growth and low dividend paying firms adjust to target leverage faster than their large, low growth and high …

Cooking A Corporation Tax Controversy: Apple, Ireland And The Eu., Ciara Graham, Brendan O'Rourke

Articles

Given the centrality of corporations in distribution of income and wealth studies, discursive constructions of corporate taxation are essential to understanding the production of inequality. The focus of this study is an interview with Apple’s Chief Executive Tim Cook on the Irish state broadcaster, Raidió Teilifís Éireann’s (RTÉ) flagship news programme, Morning Ireland, following the ruling by the European Commission (EC) on the corporation tax arrangements between Apple Inc. and Ireland. Drawing on a Critical Discourse Analysis (CDA) approach, a frame analysis is provided. The significance and extent of the EC’s ruling has potential implications for corporation taxation policy, within …

An Object-Based Multimedia Forensic Analysis Tool, Shahlaa Talib Mashhadani

School of Engineering, Computing and Mathematics Theses

With the enormous increase in the use and volume of photographs and videos, multimedia-based digital evidence now plays an increasingly fundamental role in criminal investigations. However, with the increase, it is becoming time-consuming and costly for investigators to analyse content manually. Within the research community, focus on multimedia content has tended to be on highly specialised scenarios such as tattoo identification, number plate recognition, and child exploitation. An investigator’s ability to search multimedia data based on keywords (an approach that already exists within forensic tools for character-based evidence) could provide a simple and effective approach for identifying relevant imagery. This …

Improving Group Integrity Of Tags In Rfid Systems, Reem Alkanhel

School of Engineering, Computing and Mathematics Theses

Checking the integrity of groups containing radio frequency identification (RFID) tagged objects or recovering the tag identifiers of missing objects is important in many activities. Several autonomous checking methods have been proposed for increasing the capability of recovering missing tag identifiers without external systems. This has been achieved by treating a group of tag identifiers (IDs) as packet symbols encoded and decoded in a way similar to that in binary erasure channels (BECs). Redundant data are required to be written into the limited memory space of RFID tags in order to enable the decoding process. In this thesis, the group …

Cooperative Swarm Optimisation Of Unmanned Surface Vehicles, Yogang Singh

School of Engineering, Computing and Mathematics Theses

With growing advances in technology and everyday dependence on oceans for resources, the role of unmanned surface vehicles (USVs) has increased many fold. Extensive operations of USVs having naval, civil and scientific applications are currently being undertaken in various complex marine environments and demands are being placed on them to increase their autonomy and adaptability. A key requirement for the autonomous operation of USVs is to possess a multi-vehicle framework where they can operate as a fleet of vehicles in a practical marine environment with multiple advantages such as surveying of wider areas in less time. From the literature, it …

Securing Cloud Storage By Transparent Biometric Cryptography, Leith Abed

School of Engineering, Computing and Mathematics Theses

With the capability of storing huge volumes of data over the Internet, cloud storage has become a popular and desirable service for individuals and enterprises. The security issues, nevertheless, have been the intense debate within the cloud community. Significant attacks can be taken place, the most common being guessing the (poor) passwords. Given weaknesses with verification credentials, malicious attacks have happened across a variety of well-known storage services (i.e. Dropbox and Google Drive) – resulting in loss the privacy and confidentiality of files. Whilst today's use of third-party cryptographic applications can independently encrypt data, it arguably places a significant burden …

Numerical Modelling Of Responses Of Offshore Wave Energy Converters In Extreme Waves, Pierre-Henri Musiedlak

School of Engineering, Computing and Mathematics Theses

Wave Energy is a promising sector for sustainable low-carbon energy production. Despite the effort put in the last decade, concerning problems remained unsolved. Numerical modelling can play a key role in the assessment of extreme responses necessary to the understanding of Wave Energy Converter (WEC) capacity to survive extreme conditions. However, high-fidelity codes are too time-consuming for industries, while codes of lower fidelity are based on major physical assumptions inducing concerning uncertainties. Therefore, the present study - sponsored jointly by DNV GL and the University of Plymouth - develops an hybrid model coupling the low-fidelity model WaveDyn, with a Computational …
