Cmos Approach To Compressed-Domain Image Acquisition, Javad Ghasemi, Manish Bhattarai, Glauco R.C. Fiorante, Payman Zarkesh-Ha, Sanjay Krishna, Majeed M. Hayat Jan 2017

Cmos Approach To Compressed-Domain Image Acquisition, Javad Ghasemi, Manish Bhattarai, Glauco R.C. Fiorante, Payman Zarkesh-Ha, Sanjay Krishna, Majeed M. Hayat

Electrical and Computer Engineering Faculty Research and Publications

A hardware implementation of a real-time compressed-domain image acquisition system is demonstrated. The system performs front-end computational imaging, whereby the inner product between an image and an arbitrarily-specified mask is implemented in silicon. The acquisition system is based on an intelligent readout integrated circuit (iROIC) that is capable of providing independent bias voltages to individual detectors, which enables implementation of spatial multiplication with any prescribed mask through a bias-controlled response-modulation mechanism. The modulated pixels are summed up in the image grabber to generate the compressed samples, namely aperture-coded coefficients, of an image. A rigorous bias-selection algorithm is presented to the …

Detection Theory For Accurate And Non-Invasive Skin Cancer Diagnosis Using Dynamic Thermal Imaging, Sebastian E. Godoy, Majeed M. Hayat, David A. Ramirez, Stephen A. Myers, R. Steven Padilla, Sanjay Krishna Jan 2017

Detection Theory For Accurate And Non-Invasive Skin Cancer Diagnosis Using Dynamic Thermal Imaging, Sebastian E. Godoy, Majeed M. Hayat, David A. Ramirez, Stephen A. Myers, R. Steven Padilla, Sanjay Krishna

Electrical and Computer Engineering Faculty Research and Publications

Skin cancer is the most common cancer in the United States with over 3.5M annual cases. Presently, visual inspection by a dermatologist has good sensitivity (> 90%) but poor specificity (< 10%), especially for melanoma, which leads to a high number of unnecessary biopsies. Here we use dynamic thermal imaging (DTI) to demonstrate a rapid, accurate and non-invasive imaging system for detection of skin cancer. In DTI, the lesion is cooled down and the thermal recovery is recorded using infrared imaging. The thermal recovery curves of the suspected lesions are then utilized in the context of continuous-time detection theory in order to define an optimal statistical decision rule such that the sensitivity of the algorithm is guaranteed to be at a maximum for every prescribed false-alarm probability. The proposed methodology was tested in a pilot study including 140 human subjects demonstrating a sensitivity in excess of 99% for a prescribed specificity in excess of 99% for detection of skin cancer. To the best of our knowledge, this is the highest reported accuracy for any non-invasive skin cancer diagnosis method.

Moving Between Automated And Manual Driving: Mental Workload And Performance Implications, Totsapon Butmee, Terry C. Lansdown

H-Workload 2017: Models and Applications (Works in Progress)

Automated driving has been predicted to take-over from manual vehicle control in the near future. The driver’s role may then change from active operator to passive observer. Such technology offers the tantalising promise of improving driving safety. However, many studies have presented findings suggesting potentially adverse effects from automated driving systems, e.g., reduced situation awareness. Mental workload is also a key issue of concern for researchers in this area. Excessive mental workload has repeatedly been shown to be associated with degraded driving performance. Previously, most traffic psychology studies on mental workload have focused the manual driving task. However, a shift …

Reducing Peak Workload In The Cockpit: A Human In The Loop Simulation Evaluating New Runway Selection Tool, Tanja Bos, Rolf Zon, Wilfred Rouwhorst Jan 2017

Reducing Peak Workload In The Cockpit: A Human In The Loop Simulation Evaluating New Runway Selection Tool, Tanja Bos, Rolf Zon, Wilfred Rouwhorst

H-Workload 2017: Models and Applications (Works in Progress)

In efforts to increase safety and reduce peak workload situations in the cockpit, a tool with a different interaction style was developed for use in case of a runway change instructed by Air Traffic Control during approach. In an experiment a workload comparison was made between the new tool and the conventional cockpit. Workload was measured by means of a self-rating after each experiment run, as well as eye blink frequency during each run. Results show that the self-rated workload decreases with the new tool for one of the two crew members and the blink frequency suggests a workload decrease …

Smart Workload Balancing, Ferdinand Coster Jan 2017

Smart Workload Balancing, Ferdinand Coster

H-Workload 2017: Models and Applications (Works in Progress)

The cognitive workload of operators working with automated systems should neither be too high nor too low. A static level of automation is unable to cope with systems that produce large fluctuations in cognitive workload, therefore a method for adaptive automation is proposed that could balance workload by intelligently choosing what to automate and when. To this end the concept of the Cognitive Workload Value factor is introduced, which takes into account both workload and situation awareness. This initial work introduces a possible framework for categorizing and using different workload and situation awareness measures.

Facing Human Workload: The Resilient Ego: A Psychoanalytic Point Of View, Glauco Maria Genga, Maria Gabriella Pediconii Jan 2017

Facing Human Workload: The Resilient Ego: A Psychoanalytic Point Of View, Glauco Maria Genga, Maria Gabriella Pediconii

H-Workload 2017: Models and Applications (Works in Progress)

The paper aims to show new connections among Human Factors, Human Workload and Resilience. We intend: 1) to highlight the role of subject in facing the human workload, inflected as demanding tasks and emergency situations; 2) to show how psychoanalysis can provide novel insights, not only into human errors, but also into human resilience. They have a common denominator, at least in part: the role of subjective contributions even in demanding situations. Human workload includes a work for satisfaction. We recall also the case study of US Airways Flight 1549 water landing (the so called “Miracle on the Hudson”), which …

Online Measuring Of Available Resources, Enrique Munoz-De-Escalona, José Juan Canas Jan 2017

Online Measuring Of Available Resources, Enrique Munoz-De-Escalona, José Juan Canas

H-Workload 2017: Models and Applications (Works in Progress)

This paper present a proposal for measuring available mental resources during the accomplishment of a task. Our proposal consists in measuring emotions provoked by perceived self-efficacy in the execution of the task. Self-efficacy is one of the most important factors that affect the resources that a person puts at the disposal of the execution of the task. When a person perceives that he/she is not being effective he/she will activate more resources to improve his performance. This self-efficacy will be reflected in the emotions that the person experiences. A good efficacy will provoke positive emotions and a bad efficacy negative …

The Changing Role Of The University: A Discursive Analysis Of Good Teaching And Positioning Of Academics And Students In Improving The Quality Of Teaching And Learning In Europe’S Higher Education Institutions, Fiona Mcsweeney Jan 2017

The Changing Role Of The University: A Discursive Analysis Of Good Teaching And Positioning Of Academics And Students In Improving The Quality Of Teaching And Learning In Europe’S Higher Education Institutions, Fiona Mcsweeney

Irish Journal of Academic Practice

Using the approach of critical discourse analysis this paper presents an examination of the notion of good teaching as constructed in the strategy document Improving the quality of teaching and learning in Europe’s higher education institutions. The aim is to draw attention to, and question how the language used in educational policy documents constructs particular meanings and purposes to concepts such as teaching and learning, as well as creating a particular version of the social relations within educational institutions. This in turn positions teachers and students in particular ways, constructing and limiting who they are and what they do. While …

Community-Based Learning: A Primer, Zeinab Bedri, Ruairí De Fréin, Geraldine Dowling Jan 2017

Community-Based Learning: A Primer, Zeinab Bedri, Ruairí De Fréin, Geraldine Dowling

Irish Journal of Academic Practice

Employers are increasingly demanding graduates with industry-ready communication, leadership, emotional intelligence and social ethics skills. Community-based learning (CBL) is a pedagogical approach which has tremendous potential to produce graduates with these attributes. However, for many early-career lecturers, distilling the insights from the teaching and learning literature, and then producing a well-designed CBL module, can be an intimidating task. What is missing is a primer which presents the core ideas of CBL in a way that is independent of subject-specific jargon. Ideally, this primer should provide the reader with the means of either drafting an initial project plan or, at the …

Emission, Education, And Politics: An Empirical Study Of The Carbon Dioxide And Methane Environmental Kuznets Curve, Cody Williamson Jan 2017

Emission, Education, And Politics: An Empirical Study Of The Carbon Dioxide And Methane Environmental Kuznets Curve, Cody Williamson

The Park Place Economist

This study will estimate carbon dioxide and methane emissions of 181 countries in 2012 through the use of a quadratic function of per capita GDP. Several variables will be used as controls; with GDP per capita, mean years of education, and government regime being the most important. This study estimates the emissions of carbon dioxide and methane because the EPA states that these two gasses account for roughly 92% of the worlds greenhouse gasses, thus making it vital that we have a strong understanding of both gases. Also, no literature known to the author has looked into the evidence of …

Impact Of Institutional And Political Variables On Foreign Direct Investment In Developing Countries, Hang Phung Jan 2017

Impact Of Institutional And Political Variables On Foreign Direct Investment In Developing Countries, Hang Phung

The Park Place Economist

Literature on foreign direct investment (FDI) has been focusing on its traditional determinants for a long time and lack of attention to institutional and political variables. However, in recent years, the pattern of the world FDI flows is observed to show a shift away from developed countries towards developing countries. Such shift is argued to be the result of the improvement in institutional qualities and political stability in developing countries to make investment climate more appealing to foreign investors. The impact of institutional qualities on FDI flows, however, have not been investigated by many studies in the field of FDI. …

Examining The Progress Of Female Athletes In The Marathon, Nathan Atkins Jan 2017

Examining The Progress Of Female Athletes In The Marathon, Nathan Atkins

The Park Place Economist

Unlike other sports such as baseball, basketball, football, and other team sports, the performance of a runner is not affected by the teammates around them or by an opponent’s defense. The only person that can impact the runner’s performance is the runner. At first glance, it may seem that elite marathon runners only come from African countries, but when digging deeper, the variable that makes an elite runner successful may surprise you. The purpose of this paper is to explore the variables that have the greatest impact on elite marathon runner’s performance. In addition to this, this paper attempts to …

Dynamical Systems Theory For Transparent Symbolic Computation In Neuronal Networks, Giovanni Sirio Carmantini Jan 2017

Dynamical Systems Theory For Transparent Symbolic Computation In Neuronal Networks, Giovanni Sirio Carmantini

School of Engineering, Computing and Mathematics Theses

In this thesis, we explore the interface between symbolic and dynamical system computation, with particular regard to dynamical system models of neuronal networks. In doing so, we adhere to a definition of computation as the physical realization of a formal system, where we say that a dynamical system performs a computation if a correspondence can be found between its dynamics on a vectorial space and the formal system’s dynamics on a symbolic space. Guided by this definition, we characterize computation in a range of neuronal network models. We first present a constructive mapping between a range of formal systems and …

Geospatial Drivers Of The Groundwater Δ18o Isoscape In A Temperate Maritime Climate (Republic Of Ireland), S. Regan, R. Goodhue, O. Naughton, Paul Hynds

Articles

In recent years, the concept of “isoscapes” has been used to describe spatiotemporal stable isotope distributions within natural environments including groundwater systems at multiple scales. This study presents an updated groundwater δ18O isoscape for the Republic of Ireland and describes the climatic and geological drivers influencing 18O composition. In all, 142 geographically and geologically representative groundwater installations were sampled and analysed, in addition to 35 samples from six nested boreholes. Geospatially, Irish groundwater exhibits high δ18O values in southern and western coastal regions, becoming progressively depleted inland before reaching lowest measured values along the eastern coast, equating to a national …

An Overview Of Dissolved Organic Carbon In Groundwater And Implications For Drinking Water Safety, S. Regan, Paul Hynds, R. Flynn Jan 2017

An Overview Of Dissolved Organic Carbon In Groundwater And Implications For Drinking Water Safety, S. Regan, Paul Hynds, R. Flynn

Articles

Dissolved organic carbon (DOC) is composed of a diverse array of compounds, predominantly humic substances, and is a near ubiquitous component of natural groundwater, notwithstanding climatic extremes such as arid and hyper-arid settings. Despite being a frequently measured parameter of groundwater quality, the complexity of DOC composition and reaction behaviour means that links between concentration and human health risk are difficult to quantify and few examples are reported in the literature. Measured concentrations from natural/unpolluted groundwater are typically below 4 mg C/l, whilst concentrations above these levels generally indicate anthropogenic influences and/or contamination issues and can potentially compromise water safety. …

Application Of Artificial Intelligence For Detecting Derived Viruses, Omotayo Asiru, Moses Dlamini, Jonathan Blackledge Jan 2017

Application Of Artificial Intelligence For Detecting Derived Viruses, Omotayo Asiru, Moses Dlamini, Jonathan Blackledge

Conference papers

Computer viruses have become complex and operates in a stealth mode to avoid detection. New viruses are argued to be created each and every day. However, most of these supposedly ‘new’ viruses are not completely new. Most of the supposedly ‘new’ viruses are not necessarily created from scratch with completely new (something novel that has never been seen before) mechanisms. For example, most of these viruses just change their form and signatures to avoid detection. But their operation and the way they infect files and systems is still the same. Hence, such viruses cannot be argued to be new. In …

Reactive Power Control For Smarter (Urban) Distribution Network Management With Increasing Integration Of Renewable Prosumers, Arsalan Zaidi, Keith Sunderland, Massimiliano Coppo, Michael Conlon, Roberto Turri

Conference papers

Smart cities need to deliver reliable electric energy while utilizing every renewable energy source available in a sustainable manner. Increasing renewable electricity capacity, through Distributed Generation (DG) such as small wind and PV generation, causes difficulties for the distribution network operator (DNO) in sustaining adequate and appropriate power quality across the network. The positive impacts provided by such energy sources can be undermined by voltage increases and voltage balance issues. To overcome these problems, urban distribution networks need to transform ideally into smarter energy networks that can deliver renewable electricity locally, predictably and in a controllable and optimized manner.

Design Of An Underwater Cable Fault Location Device To Precisely Locate Submarine Cable Faults, Glenn O'Reilly, Joseph Kearney, John Lawler, Tom Looby Jan 2017

Design Of An Underwater Cable Fault Location Device To Precisely Locate Submarine Cable Faults, Glenn O'Reilly, Joseph Kearney, John Lawler, Tom Looby

Conference papers

The objective of the paper is to develop a robust and reliable method to pinpoint submarine cable faults. Submarine cables have existed for over 100 years but there is still no single method used to determine the precise location of a submarine cable fault. The various methods used to pinpoint cable faults, both submarine and non-submarine were researched and investigated to produce a method which would accurately pinpoint submarine cable faults. From this, the idea of a hydrophone string was derived from a non-submarine pinpointing method currently used. The hydrophone string was tested and it accurately pinpointed the location of …

Enhanced Network Voltage Management (Nvm) Techniques Under The Proliferation Of Rooftop Solar Pv Installation In Low Voltage Distribution Network (Lvdn), Shivananda Pukhrem, Malabika Basu, Michael Conlon, Keith Sunderland Jan 2017

Enhanced Network Voltage Management (Nvm) Techniques Under The Proliferation Of Rooftop Solar Pv Installation In Low Voltage Distribution Network (Lvdn), Shivananda Pukhrem, Malabika Basu, Michael Conlon, Keith Sunderland

Articles

Proliferation of rooftop solar PV distributed generator (PVDG) installation in low voltage distribution network (LVDN) imposes voltage fluctuation challenges that are a threat to distribution system operators. Reactive power control (RPC) methods are insufficient in isolation to combat the overvoltage fluctuations manifested in LVDN with significant grid-tied PVDG installations. Whereas active power curtailment (APC) control can alleviate the voltage fluctuation in such situations and it is achieved at the cost of reduced active power injection. This paper explores how deficiencies in both RPC and APC as separate approaches can be mitigated by suitably combining RPC and APC algorithms. Strategies combining …

Legal Frameworks For Media And Information Literacy, María-Del-Mar Grandío, Sirin Dilli, Brian O'Neill

Books/Book chapters

Across Europe and beyond, efforts are growing to promote the wider use of digital media by all citizens - adults and young people alike. As such, an increasingly prominent role is being given to the notion that media literacy is a precondition for full and effective participation in contemporary societies. In such a context, interests of policymakers focusing on promoting the benefits of a wider societal digital participation intersect with the traditional function of media literacy to promote enhanced skills and competencies of citizens to access, create and understand media content. Accordingly, a concern with media literacy has moved from …

User-Centric Traffic Engineering In Software Defined Networks, Taimur Bakhshi Jan 2017

User-Centric Traffic Engineering In Software Defined Networks, Taimur Bakhshi

School of Engineering, Computing and Mathematics Theses

Software defined networking (SDN) is a relatively new paradigm that decouples individual network elements from the control logic, offering real-time network programmability, translating high level policy abstractions into low level device configurations. The framework comprises of the data (forwarding) plane incorporating network devices, while the control logic and network services reside in the control and application planes respectively. Operators can optimize the network fabric to yield performance gains for individual applications and services utilizing flow metering and application-awareness, the default traffic management method in SDN. Existing approaches to traffic optimization, however, do not explicitly consider user application trends. Recent SDN …
