Electrical and Computer Engineering Publications

In recent years, advances in sensor technologies and expansion of smart meters have resulted in massive growth of energy data sets. These Big Data have created new opportunities for energy prediction, but at the same time, they impose new challenges for traditional technologies. On the other hand, new approaches for handling and processing these Big Data have emerged, such as MapReduce, Spark, Storm, and Oxdata H2O. This paper explores how findings from machine learning with Big Data can benefit energy consumption prediction. An approach based on local learning with support vector regression (SVR) is presented. Although local learning itself is ...


Commuting By Customized Bus: A Comparative Analysis With Private Car And Conventional Public Transport In Two Cities, Tao Liu, Avishai Ceder, Romain Bologna, Benjamin Cabantous 2016 University of Auckland

Commuting By Customized Bus: A Comparative Analysis With Private Car And Conventional Public Transport In Two Cities, Tao Liu, Avishai Ceder, Romain Bologna, Benjamin Cabantous

Journal of Public Transportation

Commuting is a major component in the creation of traffic and travel problems. Thus, more attention should be given to its practice. Private car (PC) transport, the dominant mode of commuting in most of the world’s major cities, creates traffic-related social problems such as traffic congestion, traffic fatalities and injuries, and adverse environmental impacts. This study proposes a novel commuting travel mode—a customized bus (CB) transit system that provides advanced, personalized, and flexible demand-interactive minibus service using Internet, telephone, and smartphone apps. The aim was to assess and compare the performance of CB with PC and with conventional ...

eGEMs (Generating Evidence & Methods to improve patient outcomes)

Background: Challenges in the design of electronic health records (EHRs) include designing usable systems that must meet the complex, rapidly changing, and high-stakes information needs of clinicians. The ability to move and assemble elements together on the same page has significant human-computer interaction (HCI) and efficiency advantages, and can mitigate the problems of negotiating multiple fixed screens and the associated cognitive burdens.

Objective: We compare MedWISE—a novel EHR that supports user-composable displays—with a conventional EHR in terms of the number of repeat views of data elements for patient case appraisal.

Design and Methods: The study used mixed-methods for ...


Optical Analysis And Fabrication Of Micro And Nanoscale Plasmonically Enhanced Devices, Avery M. Hill 2016 University of Arkansas, Fayetteville

Optical Analysis And Fabrication Of Micro And Nanoscale Plasmonically Enhanced Devices, Avery M. Hill

Physics Undergraduate Honors Theses

Plasmonic nanostructures have been shown to act as optical antennas that enhance optical devices due to their ability to focus light below the diffraction limit of light and enhance the intensity of the incident light. This study focuses on computational electromagnetic (CEM) analysis of two devices: 1) GaAs photodetectors with Au interdigital electrodes and 2) Au thin-film microstructures. Experiments showed that the photoresponse of the interdigital photodetectors depend greatly on the electrode gap and the polarization of the incident light. Smaller electrode gap and transverse polarization give rise to a larger photoresponse. It was also shown that the response from ...


Numerical Investigation Of Full Scale Thunderstorm Downbursts: A Parametric Study And Comparison To Meteorological Model, Christopher Oreskovic 2016 The University of Western Ontario

Numerical Investigation Of Full Scale Thunderstorm Downbursts: A Parametric Study And Comparison To Meteorological Model, Christopher Oreskovic

Electronic Thesis and Dissertation Repository

A series of Large Eddy Simulations using an atmospheric meteorological cloud model have been used to investigate the important geometric and thermal parameters that influence a thunderstorm downburst outflow, as it pertains specifically to the idealized cooling source model. A separate set of Large Eddy Simulations make use of the same idealized cooling source model, in a realistic atmospheric base state using real field sounding data, in an attempt to make a quantifiable comparison to a downburst from a full cloud simulation. Randomness has been added to the cooling source forcing function to mimic the thermal variation in a real ...


Strategic Cyberwar Theory - A Foundation For Designing Decisive Strategic Cyber Operations, Jan Kallberg 2016 United States Military Academy and Army Cyber Institute at West Point

Strategic Cyberwar Theory - A Foundation For Designing Decisive Strategic Cyber Operations, Jan Kallberg

Jan Kallberg

Traditional military theory applied in cyber struggles with four challenges – anonymity, object permanence, measurable results, and rapid digital execution. In a Clausewitzian world, these challenges were non-existent. The enemy was clearly marked, the battle field was fixed, the results of the battle was visible, and it occurred not at computational speed but instead in a pace that allowed human leadership to act. Traditional military thinking does not support decisive action in a future nation state cyber conflict. The utility of cyber attacks is dependent on the institutional design of the targeted society. Strategic cyberwar theory utilizes ‘Occam’s Razor’ to ...


A Model For Complex Heat And Mass Transport Involving Porous Media With Related Applications, Furqan A. Khan 2016 The University of Western Ontario

A Model For Complex Heat And Mass Transport Involving Porous Media With Related Applications, Furqan A. Khan

Electronic Thesis and Dissertation Repository

Heat and mass transfer involving porous media is prevalent in, for example, air-conditioning, drying, food storage, and chemical processing. Such applications require non-equilibrium heat and mass (or moisture) transfer modeling inside porous media in conjugate fluid/porous/solid framework. Moreover, modeling of turbulence and turbulent heat and mass transfer becomes essential for many applications. A comprehensive literature review shows a scarcity of models having such capabilities. In this respect, the objectives of the present thesis are to: i) develop a formulation that simulates non-equilibrium heat and mass transfer in conjugate fluid/porous/solid framework, ii) demonstrate the capabilities of the ...


Effectiveness Of Soft Baseplates And Fastenings To Mitigate Track Dynamic Settlement At Transition Zone At Railway Bridge Approaches, Sakdirat Kaewunruen, A Remennikov, Akira Aikawa 2016 University of Wollongong

Effectiveness Of Soft Baseplates And Fastenings To Mitigate Track Dynamic Settlement At Transition Zone At Railway Bridge Approaches, Sakdirat Kaewunruen, A Remennikov, Akira Aikawa

Sakdirat Kaewunruen


Railway bridge approaches or bridge ends often suffer from a combination of dynamic wheel/rail interaction and poor formation compaction due to construction difficulties at the location, resulting in an initial short-wavelength track settlement at the first few sleeper bays near the bridge over a short period under revenue services. This settlement then further induces impact loading that aggravates the differential settlement, causing downtime or restricted railway operation; and importantly more frequent maintenance, which is costly and time-consuming. Principally, the stiffness transition zones can be optionally designed to either: (1) provide a gradual increase in the stiffness of ballasted track ...


“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams 2016 Liberty University

“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams

Senior Honors Theses

Alan Turing asked if machines can think, but intelligence is more than logic and reason. I ask if a machine can feel pain or joy, have visions and dreams, or paint a masterpiece. The human brain sets the bar high, and despite our progress, artificial intelligence has a long way to go. Studying neurology from a software engineer’s perspective reveals numerous uncanny similarities between the functionality of the brain and that of a computer. If the brain is a biological computer, then it is the embodiment of artificial intelligence beyond anything we have yet achieved, and its architecture is ...


Modified Numerical-Analytical Analysis On Scpps, Nima Fathi 2016 University of New Mexico

Modified Numerical-Analytical Analysis On Scpps, Nima Fathi

Nima Fathi

In this study an appropriate expression to estimate the output power of solar chimney power plant systems (SCPPS) was considered. Recently several mathematical models of SCPPS were derived, studied for a variety of boundary conditions, and compared against CFD calculations. An important concern for modeling SCPPS is the accuracy of the derived pressure drop and output power equation. To elucidate the matter, axisymmetric CFD analysis was performed to model the solar chimney power plant and calculate the output power for different available solar radiation. Both analytical and numerical results were compared against the available experimental data from the historical Manzanares ...

Responses And Vulnerability Of Composite Railway Track Slab To Train Derailments, Sakdirat Kaewunruen, Olivia Mirza, Daniel Thomson 2016 University of Birmingham

Responses And Vulnerability Of Composite Railway Track Slab To Train Derailments, Sakdirat Kaewunruen, Olivia Mirza, Daniel Thomson

Sakdirat Kaewunruen

Modern replacement of deteriorated timber transom sleepers by steel-concrete composite slabs can significantly improve asset management strategy for railway bridges over their life cycle. Track engineers can take advantage of steel-concrete composite technology over traditional concrete slabs. The design of such steel-composite track slabs has shown 10-20% reduction in the component depth and thus the weight. These benefits enable the composite slabs to fit brown-field maintenance project where merely aging transoms can be renewed and the new composite slabs can be installed over existing girders and support systems. In practice, railway bridge structure is designed to embrace redundancy assuring public ...

Fractal geometries are attractive for antenna designers seeking antennas with compact size and multiband resonant behavior. This paper presents the design of a new microstrip-fed printed slot antenna for use in dual-band wireless applications. The slot structure of the proposed antenna is in the form of Cantor square fractal geometry of the second iteration. The slot structure has been etched on the ground plane of a substrate with relative permittivity of 4.4 and 1.6 mm in thickness. A parametric study is conducted to explore the effects of some geometrical parameters on the antenna performance. Results show that the ...

Sakdirat Kaewunruen

This paper highlights a case study that investigates the behaviour of existing bridge, West Terrace Bridge, induced by horizontal seismic loading. Unfortunately the lack of past information related to seismic activity within the NSW region has made it difficult to understand better the capacity of the structure if Earthquake occurs. The research was conducted through the University of Western Sydney in conjunction with Railcorp Australia, as part of disaster reduction preparedness program. The focus of seismic analyses was on the assessment of stress behaviour, induced by cyclic horizontal/vertical displacements, within the concrete slab and steel truss of the bridge ...


Cfd Simulations And Experiments Of Meltblown Fibrous Media: New Die Designs To Enhance Fiber Attenuation And Filtration Quality, Mohammad Hassan 2016 Selected Works

Cfd Simulations And Experiments Of Meltblown Fibrous Media: New Die Designs To Enhance Fiber Attenuation And Filtration Quality, Mohammad Hassan

Mohammad Abouelreesh Hassan

The meltblowing process employs high-speed hot air jets to attenuate polymer streams injected from a die head. In this study, we examine design strategies to control the air flow field below the polymer injection point to achieve higher fiber attenuation and meltblown webs with smaller fiber diameters. Computational fluid dynamics (CFD) simulations for new die configurations show that vertical or inclined air constrictors around the primary air jets keep the centerline air velocity and temperature at their maximum values for 10–15 mm longer below the die face than the reference die. Polymer streams are kept near their melting temperatures ...


Coel: A Web-Based Chemistry Simulation Framework, Peter Banda, Drew Blount, Christof Teuscher 2016 Portland State University

Coel: A Web-Based Chemistry Simulation Framework, Peter Banda, Drew Blount, Christof Teuscher

Christof Teuscher

The chemical reaction network (CRN) is a widely used formalism to describe macroscopic behavior of chemical systems. Available tools for CRN modelling and simulation require local access, installation, and often involve local file storage, which is susceptible to loss, lacks searchable structure, and does not support concurrency. Furthermore, simulations are often single-threaded, and user interfaces are non-trivial to use. Therefore there are significant hurdles to conducting efficient and collaborative chemical research. In this paper, we introduce a new enterprise chemistry simulation framework, COEL, which addresses these issues. COEL is the first web-based framework of its kind. A visually pleasing and ...

Ms-Reduce: An Ultrafast Technique For Reduction Of Big Mass Spectrometry Data For High-Throughput Processing, Muaaz Gul Awan, Fahad Saeed 2016 WMU

Ms-Reduce: An Ultrafast Technique For Reduction Of Big Mass Spectrometry Data For High-Throughput Processing, Muaaz Gul Awan, Fahad Saeed

Parallel Computing and Data Science Lab Technical Reports

Modern proteomics studies utilize high-throughput mass spectrometers which can produce data at an astonishing rate. These big Mass Spectrometry (MS) datasets can easily reach peta-scale level creating storage and analytic problems for large-scale systems biology studies. Each spectrum consists of thousands of peaks which have to be processed to deduce the peptide. However, only a small percentage of peaks in a spectrum are useful for peptide deduction as most of the peaks are either noise or not useful for a given spectrum. This redundant processing of non-useful peaks is a bottleneck for streaming high-throughput processing of big MS data. One ...
