A Novel Computing Scheme Based On Pattern Matching For Identification Of Nephron Loss And Chronic Kidney Disease Stage, Rehan Ahmad, Basant Mohanty

Turkish Journal of Electrical Engineering and Computer Sciences

Nephrons are the basic filtering units of the kidneys. Progression of chronic kidney disease (CKD) destroys nephrons permanently. Although there are many computing schemes suggested in recent years to identify CKD stages, no computing method has been suggested for identifying the nephron loss within kidney regions during CKD progression. In this paper, a novel pattern matching-based computation scheme is proposed to detect nephron loss in the kidney regions during CKD progression. We consider image registration (IR) with different transforms and a structural similarity index algorithm (SSIM) to match patterns of ultrasound images of kidney regions to identify the nephron loss. …

Fuzzycsampling: A Hybrid Fuzzy C-Means Clustering Sampling Strategy For Imbalanced Datasets, Abdullah Maraş, Çi̇ğdem Erol

Turkish Journal of Electrical Engineering and Computer Sciences

Classification model with imbalanced datasets is recently one of the most researched areas in machine learning applications since they induce to the emergence of low-performing machine learning models. The imbalanced datasets occur if target variables have an uneven number of examples in a dataset. The most prevalent solutions to imbalanced datasets can be categorized as data preprocessing, ensemble techniques, and cost-sensitive learning. In this article, we propose a new hybrid approach for binary classification, named FuzzyCSampling, which aims to increase model performance by ensembling fuzzy c-means clustering and data sampling solutions. This article compares the proposed approaches' results not only …

Do Financial Technology Firms Influence Labour Force Outcomes In Indonesian Banks?, Paresh K. Narayan, Dinh Hoang Bach Phan

Bulletin of Monetary Economics and Banking

In this paper, we examined the influence of technology growth on labour outcomes. Using a sample of 37 Indonesian banks and data on financial technology (FinTech) firms from 1998 to 2017, we discovered that technology growth negatively influences the number of employees and positively impacts employee compensation. The role of technology in these labour market outcomes are both statistically and economically meaningful. Economically, for instance, with an increase of 1 standard deviation in the number of FinTech establishments, the number of Indonesian bank employees decreases by up to 2.30% of mean employees (equivalent to 58 employees) and employee compensation improves …

Effect Of The Homogenization Process On Titanium Oxide-Reinforced Nanocellulose Composite Membranes, Taufiq Mahsuli, Aisyah Larasati, Aminnudin Aminnudin, Jibril Maulana

Journal of Mechanical Engineering Science and Technology (JMEST)

Indonesian pineapple production can reach 200 tons per day; however, pineapples generate a significant amount of waste. Pineapple peel waste can be used to make membranes. Composite membranes containing TiO2 have dense properties, low porosity, and increase the mechanical strength of the cellulose sheet. This research uses various ultrasonic homogenizers to homogenize the distribution of nanocellulose and TiO2 (50% and 100% power with 30, 60, and 90 minutes). The casting method is used to shape the membrane. The SEM test shows that the higher the power used and the longer the sonication time, the less agglomeration of about 1.63%/ cm2 …

Journal of Mechanical Engineering Science and Technology (JMEST)

The interest in metallic foam is increasing since their cellular structures have a unique combination of properties such as high stiffness, low density, lightweight, high specific strength, and thermal insulation. Commonly, the performance of metallic foam can be improved by the heat treatment process. However, the previous heat treatment methods still present the brittle crack path and the research on heat treatments of the metal foam properties is very limited. In this study, individual parameters in stress relieving treatment that contribute to Al-Foam properties were investigated. The stress-relieving process of the samples was performed using a vacuum furnace. The composition …

Journal of Mechanical Engineering Science and Technology (JMEST)

Photocatalytic is considered a deadlock-breaking technology for renewable energy and lowering environmental pollutants. Photocatalytic efficiency efforts are improved by activating the photocatalyst to introduce an external magnetic field. This review highlights recent breakthroughs by comparing original coffee waste, activation of coffee waste with the addition of catalysts, and manipulation of spin electrons by applying external magnets. Characterization was done with FTIR to look at chemical bonds, UV-Vis with Tauc's Relation approach to measure bandgap, and material morphology using SEM EDX. The increase in photocatalyst activation aligns with the decrease in bandgap value. The rate of decline in bandgap is in …

When “Close Enough” Is Not Enough: Accommodating The Religiously Devout, Dallan F. Flake

BYU Law Review

Title VII of the Civil Rights Act of 1964 requires employers to “reasonably accommodate” employees’ religious practices that conflict with work requirements unless doing so would cause undue hardship to their business operations. Can an accommodation be reasonable if it only partially removes the conflict between an employee’s job and their religious beliefs? For instance, if a Christian employee requests Sundays off because he believes working on his Sabbath is a sin, and his employer responds by giving him Sunday mornings off to attend church services but requires him to work in the afternoon, has the employer provided a reasonable …

Microscale To Mesoscale Modeling Of The Ocean Under Tropical Cyclones: Effects Of Sea Spray And Surfactants On Tropical Cyclone Intensity And Air-Sea Gas Exchange, Breanna Lynn Cain Vanderplow

All HCAS Student Capstones, Theses, and Dissertations

Tropical cyclone intensity prediction remains a challenge despite computational and observational developments because successful intensity forecasting requires implementing a multitude of atmospheric and oceanic processes. Hurricane Maria 2017 and Hurricane Dorian 2019 serve as prime examples of rapidly intensifying storms that devastated communities in the Caribbean. A lack of understanding and parameterization of crucial physics involved in tropical cyclone intensity in existing forecast models may have led to these and other forecasting errors.

Microscale physical processes at the air-sea interface are a major factor in intensification of tropical cyclones that are often unaccounted for in forecasting models since they are …

Defragging Feminist Cyberlaw, Amanda Levendowski

Georgetown Law Faculty Publications and Other Works

In 1996, Judge Frank Easterbrook famously observed that any effort to create a field called cyberlaw would be “doomed to be shallow and miss unifying principles.” He was wrong, but not for the reason other scholars have stated. Feminism is a unifying principle of cyberlaw, which alternately amplifies and abridges the feminist values of consent, safety, and accessibility. Cyberlaw simply hasn’t been understood that way—until now.

In computer science, “defragging” means bringing together disparate pieces of data so they are easier to access. Inspired by that process, this Article offers a new approach to cyberlaw that illustrates how feminist values …
