Applied Energy Systems: Hydrostatic Fluid Power Transmission And Flow In Pipes, Jim Mcgovern Jan 2012

Applied Energy Systems: Hydrostatic Fluid Power Transmission And Flow In Pipes, Jim Mcgovern

Book/Book Chapters

This is an intentionally compact textbook or set of notes for a module addressing basic Fluid Mechanics for incompressible fluids within the context of Applied Energy Systems. Rather than attempting to cover Fluid Mechanics in a very broad and general way, two practical areas are selected in the use of fluids: hydrostatic power transmission systems and the flow of fluids through pipes and fittings. This allows the two areas to be presented in some detail, but also allows them to be sample application areas that would enable learners to put the principles of fluid mechanics into context, while developing their …

An Improved Flood Forecasting Model Of The Blue Nile River In Sudan, Gamal Abdo, Ahmed Nasr Jan 2012

An Improved Flood Forecasting Model Of The Blue Nile River In Sudan, Gamal Abdo, Ahmed Nasr

Articles

Reliable flood predictions with a reasonable lead time in the Blue Nile River in Sudan are vitally important to avoid catastrophic damages due to flooding of this river and the main River Nile. A HEC-RAS model was initially applied to the Blue Nile by representing the river as a single reach. The resulting original model was subsequently improved by including the two tributaries of the river, Rahad and Dindir, and also the two existing reservoirs, Rosaries and Sinnar, to the model. The original and the improved models were calibrated using 1988 flood data for the period from June to September …

Targeting Cell Nuclei For The Automation Of Raman Spectroscopy In Cytology, Jonathan Blackledge, Dmitri Dubovitskiy, Fiona Lyng Jan 2012

Targeting Cell Nuclei For The Automation Of Raman Spectroscopy In Cytology, Jonathan Blackledge, Dmitri Dubovitskiy, Fiona Lyng

Conference papers

Biological cell analysis has, and is still, an important aspect in medical research and clinical diagnosis. Although cytologists routinely undertake a diagnosis using optical mi-croscopy, human factors make this routine unreliable especially when it involves many consecutive tasks that are monotonous, time consuming and focus on pattern matching tasks where the patterns concerned are not always entirely clear and/or do not necessarily belong to a well defined class. Raman Spectroscopy provides the potential to generate a fundamental representation on the status of cellular conditions through the characteristics of a Raman spectrum generated by the back-scatter of a laser pulse incident …

Distributed Formal Concept Analysis Algorithms Based On An Iterative Mapreduce Framework, Ruairí De Fréin, Biao Xu, Eric Robson, Mícheál Ó Fóghlú Jan 2012

Distributed Formal Concept Analysis Algorithms Based On An Iterative Mapreduce Framework, Ruairí De Fréin, Biao Xu, Eric Robson, Mícheál Ó Fóghlú

Conference papers

While many existing formal concept analysis algorithms are efficient, they are typically unsuitable for distributed implementation. Taking the MapReduce (MR) framework as our inspiration we introduce a distributed approach for performing formal concept mining. Our method has its novelty in that we use a light-weight MapReduce runtime called Twister which is better suited to iterative algorithms than recent distributed approaches. First, we describe the theoretical foundations underpinning our distributed formal concept analysis approach. Second, we provide a representative exemplar of how a classic centralized algorithm can be implemented in a distributed fashion using our methodology: we modify Ganter’s classic algorithm …

Using Tpack As A Framework To Understand Teacher Candidates’ Technology Integration Decisions, Charles R. Graham, J. Borup, N. B. Smith Jan 2012

Using Tpack As A Framework To Understand Teacher Candidates’ Technology Integration Decisions, Charles R. Graham, J. Borup, N. B. Smith

Faculty Publications

This research uses the technological pedagogical and content knowledge (TPACK) framework as a lens for understanding howteacher candidates make decisions about the use of information and communication technology in their teaching. Pre- and post-treatment assessments required elementary teacher candidates at Brigham Young University to articulate how and why they would integrate technology in three content teaching design tasks. Researchers identified themes from student rationales that mapped to the TPACK constructs. Rationales simultaneously supported subcategories of knowledge that could be helpful to other researchers trying to understand and measure TPACK. The research showed significant student growth in the use of rationales …

The Effects Of Preventive And Detective Controls On Employee Performance And Motivation, Margaret H. Christ, Scott A. Emett, Scott L. Summers, David A. Wood Jan 2012

The Effects Of Preventive And Detective Controls On Employee Performance And Motivation, Margaret H. Christ, Scott A. Emett, Scott L. Summers, David A. Wood

Faculty Publications

We examine how two attributes of preventive and detective controls affect employee performance and employee motivation. Specifically, we examine how the extent to which controls (1) restrict employees’ autonomy, and (2) provide more or less timely feedback impacts employees’ performance and intrinsic motivation. These characteristics are the defining differences between preventive and detective controls in that preventive controls restrict employee autonomy relative to detective controls and preventive controls always provide immediate feedback; whereas, detective controls can provide either immediate feedback or delayed feedback. We conduct an experiment to examine how and why these two types of formal controls impact employees’ …

Editorial Of E-Book On Action And Language Integration, A Cangelosi Jan 2012

Editorial Of E-Book On Action And Language Integration, A Cangelosi

School of Engineering, Computing and Mathematics

Increasing theoretical and experimental research on action and language processing in humans and animals clearly demonstrates the strict interaction and co-dependence between language and action. This has been extensively demonstrated in neuroscientific investigations (e.g., Rizzolatti and Arbib, 1998; Cappa and Perani, 2003; Pulvermuller, 2003), psychology experiments (e.g., Glenberg and Kaschak, 2002; Pecher and Zwaan, 2005; Barsalou, 2008), evolutionary psychology (e.g., Corballis, 2002), and computational modeling (e.g., Cangelosi and Parisi, 2004; Massera et al., 2007; Cangelosi, 2010). All these studies have important implication both for the understanding of the action basis of cognition in natural and artificial cognitive systems, as well …

Emergent Auditory Feature Tuning In A Real-Time Neuromorphic Vlsi System., Sadique Sheik, Martin Coath, Giacomo Indiveri, Susan L. Denham, Thomas Wennekers, Elisabetta Chicca Jan 2012

Emergent Auditory Feature Tuning In A Real-Time Neuromorphic Vlsi System., Sadique Sheik, Martin Coath, Giacomo Indiveri, Susan L. Denham, Thomas Wennekers, Elisabetta Chicca

School of Engineering, Computing and Mathematics

Many sounds of ecological importance, such as communication calls, are characterized by time-varying spectra. However, most neuromorphic auditory models to date have focused on distinguishing mainly static patterns, under the assumption that dynamic patterns can be learned as sequences of static ones. In contrast, the emergence of dynamic feature sensitivity through exposure to formative stimuli has been recently modeled in a network of spiking neurons based on the thalamo-cortical architecture. The proposed network models the effect of lateral and recurrent connections between cortical layers, distance-dependent axonal transmission delays, and learning in the form of Spike Timing Dependent Plasticity (STDP), which …

Sigma Terms And Strangeness Content Of The Nucleon With N F  = 2 + 1 + 1 Twisted Mass Fermions, Simon Dinter, Vincent Drach, Roberto Frezzotti, Gregorio Herdoiza, Karl Jansen, Giancarlo Rossi

School of Engineering, Computing and Mathematics

Abstract We study the nucleon matrix elements of the quark scalar-density operator using maximally twisted mass fermions with dynamical light (u,d), strange and charm degrees of freedom. We demonstrate that in this setup the nucleon matrix elements of the light and strange quark densities can be obtained with good statistical accuracy, while for the charm quark counterpart only a bound can be provided. The present calculation which is performed at only one value of the lattice spacing and pion mass serves as a technical feasibility study for a future computation of the scalar quark content of the nucleon with a …

An Insider Misuse Threat Detection And Prediction Language, Georgios Vasilios Magklaras Jan 2012

An Insider Misuse Threat Detection And Prediction Language, Georgios Vasilios Magklaras

School of Engineering, Computing and Mathematics Theses

Numerous studies indicate that amongst the various types of security threats, the problem of insider misuse of IT systems can have serious consequences for the health of computing infrastructures. Although incidents of external origin are also dangerous, the insider IT misuse problem is difficult to address for a number of reasons. A fundamental reason that makes the problem mitigation difficult relates to the level of trust legitimate users possess inside the organization. The trust factor makes it difficult to detect threats originating from the actions and credentials of individual users. An equally important difficulty in the process of mitigating insider …

Gauge Invariant Constructions In Yang-Mills Theories, Poonam Sharma Jan 2012

Gauge Invariant Constructions In Yang-Mills Theories, Poonam Sharma

School of Engineering, Computing and Mathematics Theses

Understanding physical configurations and how these can emerge from the underlying gauge theory is a fundamental problem in modern particle physics. This thesis investigates the study of these configurations primarily focussing on the need for gauge invariance in constructing the gauge invariant fields for any physical theory. We consider Wu’s approach to gauge invariance by identifying the gauge symmetry preserving conditions in quantum electrodynamics and demonstrate how Wu’s conditions for one-loop order calculations (under various regularisation schemes) leads to the maintenance of gauge invariance. The need for gauge invariance is stressed and the consequences discussed in terms of the Ward …

An Analysis Of Eastern European Liner Shipping During The Period Of Transition, Heidi Rebecca Cottam Jan 2012

An Analysis Of Eastern European Liner Shipping During The Period Of Transition, Heidi Rebecca Cottam

School of Engineering, Computing and Mathematics Theses

Transition in Europe is one of the most important transformations in modern history. This research investigates the impact of economic and political transition on the liner sector of post-Soviet Europe. Former socialist shipping corporations have begun to offer services under market conditions and left behind the rigid leeway of central planning (Cottam and Roe 2007). Extensive adjustments in ownership, organisation, fleets and markets have transpired. Successful transformation of the maritime industries has a major influence upon the speed and route of economic development in transition countries (Von Brabant 2011). Despite this, liner shipping has received very little attention from academia. …

User-Centric Quality Of Service Provisioning In Ip Networks, Mark Culverhouse

School of Engineering, Computing and Mathematics Theses

The Internet has become the preferred transport medium for almost every type of communication, continuing to grow, both in terms of the number of users and delivered services. Efforts have been made to ensure that time sensitive applications receive sufficient resources and subsequently receive an acceptable Quality of Service (QoS). However, typical Internet users no longer use a single service at a given point in time, as they are instead engaged in a multimedia-rich experience, comprising of many different concurrent services. Given the scalability problems raised by the diversity of the users and traffic, in conjunction with their increasing expectations, …

On The Evolutionary Co-Adaptation Of Morphology And Distributed Neural Controllers In Adaptive Agents, Mariagiovanna Mazzapioda

School of Engineering, Computing and Mathematics Theses

The attempt to evolve complete embodied and situated artificial creatures in which both morphological and control characteristics are adapted during the evolutionary process has been and still represents a long term goal key for the artificial life and the evolutionary robotics community. Loosely inspired by ancient biological organisms which are not provided with a central nervous system and by simple organisms such as stick insects, this thesis proposes a new genotype encoding which allows development and evolution of mor- phology and neural controller in artificial agents provided with a distributed neural network. In order to understand if this kind of …
