A Formal Homogenization Approach to Piping Flow Erosion with Deposition in a Spatially Heterogeneous Soil

Adu Sakyi, Peter Amoako-Yirenkyi & Isaac Kwame Dontwi · Journal of Advances in Mathematics and Computer Science · 2020

We model and simulate piping erosion phenomena with deposition in a spatially heterogeneous soil mass motivated by seepage flow. The soil is considered to be a porous media with periodic positioning of pores spread around cylindrical structures or microstructures making the heter...

A Rigorous Homogenization for a Two-Scale Convergence Approach to Piping Flow Erosion with Deposition in a Spatially Heterogeneous Soil

Adu Sakyi, Peter Amoako-Yirenkyi & Isaac Kwame Dontwi · Journal of Advances in Mathematics and Computer Science · 2020

We present a rigorous homogenization approach to modelling piping flow erosion in a spatially heterogeneous soil. The aim is to provide a justication to a formal homogenization approach to piping flow erosion with deposition in a spatially heterogeneous soil. Under the assumption...

Time-Frequency Coherence and Forecast Analysis of Selected Stock Returns in Ghana Using Haar Wavelet

Rhydal Esi Eghan, Peter Amoako-Yirenkyi, Akoto Yaw Omari-Sasu & Nana Kena Frimpong · Journal of Advances in Mathematics and Computer Science · 2019

Aims/ objectives: The study seeks to analyze the correlation of some selected stock returns with respect to both time and frequency domain, and also to forecast returns using Wavelet Coherence and Wavelet-ARIMA model as alternative to Pearson correlation and ARIMA model respectiv...

Cantor's Ternary Set Formula-Basic Approach

W. Obeng-Denteh, Peter Amoako-Yirenkyi & James Owusu Asare · Journal of Advances in Mathematics and Computer Science · 2015

Georg Cantor (1845-1918) introduced the notion of the cantor set, which consists of points along a single line segment with a number of remarkable and deep properties. This paper aims to emphasize a proceeding to obtain the Cantor (ternary) set, C by means of the so-called elimin...

Human Fatigue Characterization and Detection Using the Eyelid State and Kalman Filter

Dominic Asamoah, Emmanuel Ofori Oppong, Peter Amoako-Yirenkyi & Stephen Opoku Oppong · Asian Journal of Research in Computer Science · 2019

One of the most promising commercial applications of Human Computer Interface is the vision based Human fatigue detection systems. Most methods and algorithms currently rely heavily on movement of the head and the colorization of the eye ball. In this paper, a new algorithm for d...
