Strong Stability Of A Class Of Difference Equations Of Continuous Time And Structured Singular Value Problem, Qian Ma, Keqin Gu, Narges Choubedar 2018 Nanjing University of Science and Technology

Strong Stability Of A Class Of Difference Equations Of Continuous Time And Structured Singular Value Problem, Qian Ma, Keqin Gu, Narges Choubedar

SIUE Faculty Research, Scholarship, and Creative Activity

This article studies the strong stability of scalar difference equations of continuous time in which the delays are sums of a number of independent parameters tau_i, i = 1, 2, . . . ,K. The characteristic quasipolynomial of such an equation is a multilinear function of exp(-tau_i s). It is known that the characteristic quasipolynomial of any difference equation set in the form of one-delayper- scalar-channel (ODPSC) model is also in such a multilinear form. However, it is shown in this article that some multilinear forms of quasipolynomials are not characteristic quasipolynomials of any ODPSC difference equation set. The equivalence between local strong ...


Application Of Pca To Cardiac Optical Mapping, Louis Woodhams 2017 Washington University in St. Louis

Application Of Pca To Cardiac Optical Mapping, Louis Woodhams

Engineering and Applied Science Theses & Dissertations

Structural remodeling of the heart due to pathologies such as hypertension and myocardial infarction leads to the appearance of myofibroblasts, a phenotype largely absent in physiologic myocardium. While myofibroblasts are responsible for wound healing and structural repair of damaged myocardium, they are thought to have deleterious effects on electrical and mechanical properties of the heart. Understanding these effects is critical to developing effective treatments, and has motivated the development of a series of in vitro engineered heart tissues and cardiomyocyte-myofibroblast co-cultures whose mechanical and electrophysiological function can be deduced from video analysis. Electrophysiological properties are evident from changes in intensity ...

A Framework Towards Technology Creation In Africa: Focusing On Ghana, Martin Yao Donani, Hannatu Abue Kugblenu, Azindow Bawa Fuseini

International Journal of African Development

Underdevelopment in Africa has been historical and a global concern coupled with the quest for good governance. Several efforts have been made in academia, national governments, the international community, and other institutional arrangements to reverse the trend. These efforts however are yet to produce a lasting result as Africa is still characterized by low productivity output, poverty and a widening technology gap when compared to other developing regions of the world. Conventional approaches used to address the African problem have consistently been devoid of indigenous technology development. Technology is here seen as paramount to every form of production on which ...


Prognosis Of Anterior Cruciate Ligament Reconstruction: A Data-Driven Approach, Abhijit Chandra, Oliva Kar, Kuan Chuen Wu, Michelle Hall, Jason C. Gillette 2017 Iowa State University

Prognosis Of Anterior Cruciate Ligament Reconstruction: A Data-Driven Approach, Abhijit Chandra, Oliva Kar, Kuan Chuen Wu, Michelle Hall, Jason C. Gillette

Jason C Gillette

Individuals who suffer anterior cruciate ligament (ACL) injury are at higher risk of developing knee osteoarthritis (OA) and almost 50% display symptoms 10–20 years post injury. Anterior cruciate ligament reconstruction (ACLR) often does not protect against knee OA development. Accordingly, a multi-scale formulation for data-driven prognosis (DDP) of post-ACLR is developed. Unlike traditional predictive strategies that require controlled off-line measurements or ‘training’ for determination of constitutive parameters to derive the transitional statistics, the proposed DDP algorithm relies solely on in situmeasurements. The proposed DDP scheme is capable of predicting onset of instabilities. As the need for off-line testing ...

Museum Wave Tank Design, David James Streng, Lisa Michelle Dischinger, John Frederick Niemoller

Mechanical Engineering

The Santa Maria Discovery Museum would like to add a tsunami wave tank to be one of their demonstrations. The wave tank needs to draw the attention of their young crowd and be educationally informative about the shapes and effects of waves. As this is a museum demonstration for children, the structure, user interface, and wave making mechanism must be durable.

We are a senior project team from California Polytechnic State University that worked on this project with Allan Hancock College and Stanford University. We created waves by rapidly moving a plunger vertically in the water column. This project allows ...

Design And Validation Of An Experimental Setup To Study Single Phase Heat Transfer Enhancement Of Femtosecond Laser Processed Metallic Surfaces, Sarah Jane Wallis 2017 University of Nebraska-Lincoln

Design And Validation Of An Experimental Setup To Study Single Phase Heat Transfer Enhancement Of Femtosecond Laser Processed Metallic Surfaces, Sarah Jane Wallis

Mechanical (and Materials) Engineering -- Dissertations, Theses, and Student Research

In the present work, a single phase flow heat transfer experimental loop was designed with the intention of studying the effects of femtosecond laser surface processing (FLSP) on metallic surfaces with the specific goal of enhancing heat transfer in compact heat exchangers currently in use by NASA. This experimental setup went through two major design iterations which are detailed in this thesis. The first iteration consisted of a counterflow fluid-to-fluid heat exchanger, which measured overall heat transfer coefficients and pressure drops, where the overall heat transfer coefficient is defined in terms of the total thermal resistance to heat transfer between ...

A Comparison Between Self-Cleaning Properties Via Rolling Droplets And Condensation On Superhyrophobic Surfaces, David Leland Miller 2017 Brigham Young University

A Comparison Between Self-Cleaning Properties Via Rolling Droplets And Condensation On Superhyrophobic Surfaces, David Leland Miller

All Theses and Dissertations

Superhydrophobic (SH) surfaces are super water repellent surfaces on which a droplet of water will bead up like a marble and roll off the surface with minimal tilting of the surface. This is caused by the combination of a hydrophobic coating and a rough surface structure. To achieve thermodynamic stability, surface tension of the water pulls the droplet into this shape to minimize the contact area between the droplet and the surface. This creates a high contact angle (CA) between the droplet and the surface and a low sliding angle (SA) of which the droplet begins to roll off the ...


Trading Off Sound Pressure Level And Average Power Production For Wind Farm Layout Optimization, Eric Tingey, Andrew Ning 2017 Brigham Young University

Trading Off Sound Pressure Level And Average Power Production For Wind Farm Layout Optimization, Eric Tingey, Andrew Ning

All Faculty Publications

This research explores the trade-offs between a wind farm’s average power production and noise impact on nearby observers. Two specific wind farm designs were studied and optimized using the FLORIS wake model and an acoustic model based on semi-empirical turbine noise calculations. It was found in the two wind farms that the average power production could be increased, up to 8.01% in one and 3.63% in the other, ignoring sound level considerations. Including a noise restriction in the optimization had a minimal impact on the optimal average power production within about a five-decibel range. Past this range ...

Composite Structures Using Asphalt Based Roofing Scrap Materials: Eiera -- Final Report, V. J. Flanigan, K. Chandrashekhara, Susan L. Murray

Susan L. Murray

The uses of recycled materials in composites provide the potential for large cost savings and a solution to the ever-growing disposal problem. Shingles contain petroleum based binders and fillers, which used as a valuable resource in composite production. Composites offer inherent advantages over traditional materials in regard to corrosion resistance, design flexibility and extended service life. Use of scrap-roofing shingles as a core material in glass fiber reinforced composite materials offer potential low cost composite products such as sound barrier system, railroad ties and other building materials including blocks. In the present work, processes have been developed for shredding scrap ...


Free-Surface Wall-Jet Flow At Moderate Reynolds Number As Applied To Slot And Blade Coating, Mohammad Tanvir Hossain 2017 The University of Western Ontario

Free-Surface Wall-Jet Flow At Moderate Reynolds Number As Applied To Slot And Blade Coating, Mohammad Tanvir Hossain

Electronic Thesis and Dissertation Repository

The flow of a two-dimensional steady wall jet observed in the slot and blade coating processes has been examined theoretically near the channel exit. The Newtonian free surface jet emerges from a channel and deposits onto an infinite moving wall with an adverse or favorable pressure gradient applied inside the channel. The Reynolds number considered is within the moderate range, and fully developed Couette-Poisueille flow conditions are assumed to prevail far upstream inside the channel. The effects of inertia and pressure gradient on the velocity, the shape of the free surface, and the stress are emphasized. It is found that ...

Development, Energy, And Climate Change Policy: Enabling Sustainable Development Through Access To Energy, Robert J. Brecha 2017 University of Dayton

Development, Energy, And Climate Change Policy: Enabling Sustainable Development Through Access To Energy, Robert J. Brecha

The Social Practice of Human Rights: Charting the Frontiers of Research and Advocacy

Human rights, human development, and climate change clearly overlap in many ways. Development, as quantified by the Human Development Index (HDI), for example, has historically been strongly correlated with energy consumption. This fact is recognized in Sustainable Development Goal (SDG) 7, to “ensure access to affordable, reliable, sustainable and modern energy for all.” Currently the world is in the midst of a large wave of human migration, much of it involuntary and due to stymied development opportunities as well as political upheaval. Climate change will become, or already is, an exacerbating factor in migration dynamics.

A pertinent question is how ...
