FPAENet: Pneumonia Detection Network Based on Feature Pyramid Attention Enhancement [PDF]
arXiv, 2020 Automatic pneumonia Detection based on deep learning has increasing clinical value. Although the existing Feature Pyramid Network (FPN) and its variants have already achieved some great successes, their detection accuracies for pneumonia lesions in medical images are still unsatisfactory. In this paper, we propose a pneumonia detection network based on

Barqi Breed Sheep Weight Estimation based on Neural Network with Regression [PDF]
arXiv, 2018 Computer vision is a very powerful method for understanding the contents from the images. We tried to utilize this powerful technology to make the difficult task of estimating sheep weights quick and accurate. It has enabled us to minimize the human involvement in measuring weight of the sheep.

Sheep Collisions: the Good, the Bad, and the TBI [PDF]
arXiv, 2007 The title page of Chapter 9 in Fundamentals of Physics (Halliday, Resnick, and Walker, 8th Edition, p. 201) shows a dramatic photograph of two Big Horn sheep butting heads and promises to explain how sheep survive such violent clashes without serious injury. However, the answer presented in sample problem 9-4 (p.

Pinball-OCSVM for early-stage COVID-19 diagnosis with limited posteroanterior chest X-ray images [PDF]
arXiv, 2020 The infection of respiratory coronavirus disease 2019 (COVID-19) starts with the upper respiratory tract and as the virus grows, the infection can progress to lungs and develop pneumonia. The conventional way of COVID-19 diagnosis is reverse transcription polymerase chain reaction (RT-PCR), which is less sensitive during early stages; especially if the

Massive viral replication and cytopathic effects in early COVID-19 pneumonia [PDF]
arXiv, 2020 SARS-CoV-2 is the cause of COVID-19 acute respiratory illness that like its predecessors, MERS and SARS, can be severe and fatal 1-4. By April of 2020, COVID-19 infections had become a worldwide pandemic with nearly 3 million infections and over 200,000 deaths. The relative contributions of virus replication and cytopathic effects or immunopathological

Evolving Shepherding Behavior with Genetic Programming Algorithms [PDF]
arXiv, 2016 We apply genetic programming techniques to the `shepherding' problem, in which a group of one type of animal (sheep dogs) attempts to control the movements of a second group of animals (sheep) obeying flocking behavior. Our genetic programming algorithm evolves an expression tree that governs the movements of each dog. The operands of the tree are hand-

Diagnosis of Patients with Viral, Bacterial, and Non-Pneumonia Based on Chest X-Ray Images Using Convolutional Neural Networks [PDF]
arXivAccording to the World Health Organization (WHO), pneumonia is a disease that causes a significant number of deaths each year. In response to this issue, the development of a decision support system for the classification of patients into those without pneumonia and those with viral or bacterial pneumonia is proposed.

Robotic Shepherding in Cluttered and Unknown Environments using Control Barrier Functions [PDF]
arXivThis paper introduces a novel control methodology designed to guide a collective of robotic-sheep in a cluttered and unknown environment using robotic-dogs. The dog-agents continuously scan the environment and compute a safe trajectory to guide the sheep to their final destination.

A First Principles Investigation of Native Interstitial Diffusion in Cr2O3 [PDF]
arXiv, 2018 First principles density functional theory (DFT) investigation of native interstitials and the associated self-diffusion mechanisms in {\alpha}-Cr2O3 reveals that interstitials are more mobile than vacancies of corresponding species. Cr interstitials occupy the unoccupied Cr sublattice sites that are octahedrally coordinated by 6 O atoms, and O ...
