Deep Learning Based Fast Mode Decision In Hevc Intra Prediction Using Region Wise Feature Classification, Shiba Prasad Kuanar

Electrical Engineering Dissertations - Archive

The High Efficiency Video Coding (HEVC) standard has achieved best coding efficiency as compared to previous H.264/AVC standard. But the computational time of HEVC encoder has increased mainly because of the hierarchical quad-tree based structure, recursive search for finding the best coding units, and the exhaustive prediction search up-to 35 modes. These advances improve the coding efficiency, but result into a very high computational complexity. Furthermore selecting the optimal modes among all prediction modes are necessary for the subsequent rate distortion optimization process.Therefore we propose a convolutional neural network (CNN) based algorithm which learns the region wise image features and …

Defending Neural Networks Against Adversarial Examples, Armon Barton

Computer Science and Engineering Dissertations - Archive

Deep learning is becoming a technology central to the safety of cars, the security of networks, and the correct functioning of many other types of systems. Unfortunately, attackers can create adversarial examples, small perturbations to inputs that trick deep neural networks into making a misclassification. Researchers have explored various defenses against this attack, but many of them have been broken. The most robust approaches are Adversarial Training and its extension, Adversarial Logit Pairing, but Adversarial Training requires generating and training on adversarial examples from any possible attack. This is not only expensive, but it is inherently vulnerable to novel attack …

Soy- Based Flexographic Ink For Linerboard Printing, Rahul Ramchandra Pingale

Masters Theses

Many printing inks use volatile solvents in the formulation, which are hazardous to the environment from emission of VOC’s and at the same time, synthetic resins in these inks are not biodegradable. These problems with the fluctuating and rising price of petroleum are main reasons to look for new resources for making more environmentally friendly printing inks. The majority of the commercially available water based inks are formulated based on using acrylic resins, synthetic colorants, solvents/water and additives, which are the common main components for formulating printing inks. In this research, soy proteins were tested for their suitability to partially …

Larval Food Limitation In A Speyeria Butterfly (Nymphalidae): How Many Butterflies Can Be Supported?, Ryan I. Hill, Cassidi E. Rush, John Mayberry

College of the Pacific Faculty Articles

For herbivorous insects the importance of larval food plants is obvious, yet the role of host abundance and density in conservation are relatively understudied. Populations of Speyeria butterflies across North America have declined and Speyeria adiaste is an imperiled species endemic to the southern California Coast Ranges. In this paper, we study the link between the food plant Viola purpurea quercetorum and abundance of its herbivore Speyeria adiaste clemencei to better understand the butterfly’s decline and aid in restoration of this and other Speyeria species. To assess the degree to which the larval food plant limits adult abundance of S. …

Assessing Ground Penetrating Radar's Ability To Image Subsurface Characteristics Of Icy Debris Fans In Alaska And New Zealand, Robert W. Jacob, Jeffrey M. Trop, R. Craig Kochel

Faculty Journal Articles

Icy debris fans have recently been described as fan shaped depositional landforms associated with (or formed during) deglaciation, however, the subsurface characteristics remain essentially undocumented. We used ground penetrating radar (GPR) to non-invasively investigate the subsurface characteristics of icy debris fans (IDFs) at McCarthy Glacier, Alaska, USA and at La Perouse Glacier, South Island of New Zealand. IDFs are largely unexplored paraglacial landforms in deglaciating alpine regions at the mouths of bedrock catchments between valley glaciers and icecaps. IDFs receive deposits of mainly ice and minor lithic material through different mass-flow processes, chiefly ice avalanche and to a lesser extent …

Scientists have performed experiments with spinal cord stimulation (SCS) to enable voluntary motor function of paralyzed patients. However, the experimentation on the human spinal cord is not a trivial task. Therefore, modeling and simulation techniques play a significant role in understanding the underlying concepts and mechanics of the spinal cord stimulation. In this work, simulation and modeling techniques related to spinal cord stimulation were investigated. The initial work was intended to visualize the electric field distribution patterns in …

The Emperor's New Clothes: How The New Atheists Are Reminding The Humanities Of Their Place And Purpose In Society., David Ira Buckner

Electronic Theses and Dissertations

This dissertation will examine the social and intellectual impact of the so-called “New Atheism” as evidenced by the writings and public careers of its four principal protagonists: evolutionary biologist Richard Dawkins, philosopher Daniel Dennett, journalist Christopher Hitchens, and neuroscientist Sam Harris. I will argue that the New Atheists together provide an account of reality philosophically superior to that of theism, including those superficially sophisticated variations espoused in the writings of scholars William Lane Craig, John Lennox, Allister McGrath, Alvin Plantinga, etc. Yet, even if this were not so, I would still contend that the accessible, informative, and provocative style of …

Is Macrolide And Beta-Lactam Combination Therapy Associated With Early Clinical Stability Or 30 Day Mortality In Hospitalized Patients With Pneumonia? An Assessment Of Confounding By Indication., Evangeline Pierce

Electronic Theses and Dissertations

Pneumonia and influenza are one of the leading causes of infectious disease-related deaths worldwide. Current guidelines for the treatment of hospitalized patients with community acquired pneumonia (CAP) include empiric antimicrobial therapy with a macrolide and a beta-lactam. There is little consensus among studies as to which antimicrobial regimen is best. The confusing results seen may very well be due to lack of assessment of confounding by indication (CBI). This analysis was a secondary analysis from Hospitalized Adults with Pneumococcal Pneumonia: Incidence Study (HAPPI). The study participants were those in HAPPI who had received either macrolide and beta-lactam combination therapy or …

Investigating The Unique Reactivity Of Novel Hx (X=Cl, Br) Reagents With Alkenes And Alkynes., Rene E. Ebule

Electronic Theses and Dissertations

The addition of hydrogen halides to carbon-carbon unsaturated systems is a classic synthetic transformation that gives rise to a variety of halogenated products as well as building blocks.¹ The different routes to achieve hydrohalogenation make use of the hydrogen halides either in the gaseous form² or in solution³, or their surrogates⁴. Only second to dihalogens, hydrogen halides are the most atom efficient source of halogenation. However, hydrogen halides are reactive gases at ambient temperature, posing a major challenge in their application. Handling gaseous hydrogen halide reagents requires expert knowledge and specialized equipment. We have …

The Regional Distribution And Molecular Interactions Of Phospholipids And Glucose In Mammalian Vitreous Humors., Abigail Nicole Schnepf

Electronic Theses and Dissertations

The vitreous humor (VH) is located in between the lens and the retina. It is composed of 98% water, hyaluronan (HA), collagen, proteins, phospholipids (PLs), and other metabolites. With aging, the VH undergoes liquefaction, a process that causes the gel-like structure of the VH to turn into a liquid and can lead to serious ocular diseases, including retinal detachment, vitreal detachment, and macular hole formation. The liquefaction process is expedited in diabetic VHs. This project focuses on understanding the molecular changes that lead to liquefaction and the reasons for which this process is accelerated with diabetes.

Novel Regulatory Pathways Of Protein Channels, Sheenah Lynn Bryant

Boise State University Theses and Dissertations

Since the proposal of the fluid mosaic model of a cell membrane, substantial scientific evidence has shown that the cell membrane is not simply an inert structure with the sole role of separating two chemically different environments. The cell membrane dynamically satisfies basic needs, such as water, ion and nutrient transport, without which the cell could not survive. It is a structure which actively participates in a great variety of physiological functions. The activity of the cell membrane is responsible for the contraction of our muscles and information processing in our brain. In order to participate in such a wide …

Privacy Spaces, Bert-Jaap Koops

West Virginia Law Review

Privacy literature contains conceptualizations of privacy in relation to role-playing and identity construction, and in relation to access control and boundary-management. In this paper, I combine both strands to introduce the concept of privacy spaces: spaces in which you can play, in your own way, the relevant role(s) you have in social life. Drawing from privacy conceptions in legal scholarship, philosophy, sociology, anthropology, human geography, and psychology, a systematic overview of traditional privacy spaces is offered, including mental bubbles, the body, personal space, personal writings, the home, private conversation space, cars, stalls, intimacy bubbles, professional black boxes, coffee house spaces, …
