Machine Learning Integrated in Wavelet Shrinkage (MLShrink)
Dixon Vimalajeewa, Vijini Lakmini, Brani Vidakovic
Data encountered in practice are frequently contaminated by additive noise, and wavelet shrinkage remains a fundamental tool for recovering underlying signals in nonparametric esti…
SCOPE Shrinkage: A Unified Framework for Wavelet Denoising
Dixon Vimalajeewa, Vijini Lakmini, Malith Premarathna +2
We introduce Symmetric CDF Oriented Probability Enhanced (SCOPE) shrinkage, a unified family of sign-preserving shrinkage rules constructed from centered cumulative distribution fu…
A Multiscale Approach for Enhancing Weak Signal Detection
Dixon Vimalajeewa, Ursula U. Muller, Brani Vidakovic
Stochastic resonance (SR), a phenomenon originally introduced in climate modeling, enhances signal detection by leveraging optimal noise levels within non-linear systems. Tradition…
A Noise Resilient Approach for Robust Hurst Exponent Estimation
Malith Premarathna, Fabrizio Ruggeri, Dixon Vimalajeewa
Understanding signal behavior across scales is vital in areas such as natural phenomena analysis and financial modeling. A key property is self-similarity, quantified by the Hurst…
Ovarian Cancer Diagnostics using Wavelet Packet Scaling Descriptors
Raymond J. Hinton, Jihyun Byun, Dixon Vimalajeewa +1
Detecting early-stage ovarian cancer accurately and efficiently is crucial for timely treatment. Various methods for early diagnosis have been explored, including a focus on featur…
Utilizing Wavelet Transform in the Analysis of Scaling Dynamics for Milk Quality Evaluation
Devon Maywald, Dixon Vimalajeewa
Food safety and quality are paramount concerns worldwide, especially concerning nutritional quality and its impact on human health. Ensuring the accuracy and efficiency of milk qua…
A Method for Detecting Murmurous Heart Sounds based on Self-similar Properties
Dixon Vimalajeewa, Chihoon Lee, Brani Vidakovic
A heart murmur is an atypical sound produced by the flow of blood through the heart. It can be a sign of a serious heart condition, so detecting heart murmurs is critical for ident…
Early Detection of Ovarian Cancer by Wavelet Analysis of Protein Mass Spectra
Dixon Vimalajeewa, Scott Alan Bruce, Brani Vidakovic
Accurate and efficient detection of ovarian cancer at early stages is critical to ensure proper treatments for patients. Among the first-line modalities investigated in studies of…
Gamma-Minimax Wavelet Shrinkage with Three-Point Priors
Dixon Vimalajeewa, Brani Vidakovic
In this paper we propose a method for wavelet denoising of signals contaminated with Gaussian noise when prior information about the -energy of the signal is available. Assumi…
Channel Capacity of Starch and Glucose Molecular Communications in the Small Intestine Digestive Tract
Dixon Vimalajeewa, Sasitharan Balasubramaniam
The emerging field of Molecular Communication (MC) aims to characterize biological-based signaling environment through information that are encoded into molecules. Since the birth…
Digestive System Dynamics in Molecular Communication Perspectives
Dixon Vimalajeewa, Sasitharan Balasubramaniam
Consumption of food in excess of the required optimal nutritional requirements has already resulted in a global crisis and this is from the perspective of human health, such as obe…
Block Chain and Internet of Nano-Things for Optimizing Chemical Sensing in Smart Farming
Dixon Vimalajeewa, Subhasis Thakur, John Breslin +2
The use of Internet of Things (IoT) with the Internet of Nano Things (IoNT) can further expand decision making systems (DMS) to improve reliability as it provides a new spectrum of…
