It has been observed that the input space of deep neural network classifiers can exhibit `fragmentation', where the model function rapidly changes class as the input space is traversed. The severity of this fragmentation tends to follow the double de

In the classic measurement error framework, covariates are contaminated by independent additive noise. This paper considers parameter estimation in such a linear errors-in-variables model where the unknown measurement error distribution is heterosced

Abstract Background Diaphyseal radius and ulna fractures require surgical fixation in adults. Open reduction and internal fixation (ORIF) have been considered the gold standard of treatment. The recent development of an interlocking intramedullary na

Galactic cosmic rays (GCRs) are affected by solar modulation while they propagate through the heliosphere. The study of the time variation of GCR spectra observed at Earth can shed light on the underlying physical processes, specifically diffusion an

The Population Stability Index (PSI) is a widely used measure in credit risk modeling and monitoring within the banking industry. Its purpose is to monitor for changes in the population underlying a model, such as a scorecard, to ensure that the curr

The precision measurements of galactic cosmic ray protons from PAMELA and AMS are reproduced using a well-established 3D numerical model for the period July 2006 - November 2019. The resulting modulation parameters are applied to simulate the modulat

Travelling families contribute significantly to the domestic tourism market in South Africa. This study aimed to determine why families go on holiday and what their needs are during a holiday from the perspective of a mother. A quantitative study was

Existing literature on social media groups’ identity in South Africa is both outdated and insufficient, notably lacking a comprehensive exploration of ethnic identity and demographic disparities. Previous research in South Africa has examined socia

A well-established, comprehensive 3-D numerical modulation model is applied to simulate galactic protons, electrons and positrons from May 2011 to May 2015, including the solar magnetic polarity reversal of Solar Cycle 24. The objective is to evaluat
