A portfolio diversification measure in the unit interval: A coherent and practical approach

open access: yesInternational Journal of Finance &Economics, EarlyView.
Abstract In this article, we introduce and examine the efficiency of a portfolio diversification measure. Using the recently developed coherence properties for diversification measures as well as other criteria, we show that the novel measure outperforms the most commonly used diversification measures.

Transmission Water Losses at South African Irrigation Schemes: A Case Study of the Vaalharts Irrigation Scheme

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Irrigation water supply is under scrutiny because of dwindling water resources. Most irrigation water in South Africa (SA) is transmitted by canals. Transmission water loss (TWL) accounts for 12% of the irrigation water losses in SA. Therefore, there is a need to investigate and understand the major parameters influencing TWL at Vaalharts ...

PolSpec: Polarisation‐Based Detection for Versatile, Cost‐Effective Rapid Hyperspectral Imaging

open access: yesJournal of Biophotonics, EarlyView.
“PolSpec” is a fast, flexible, data efficient and cost‐effective technique for hyperspectral imaging utilising polarisation‐based spectral modulation. Using data‐efficient representation of spectral information on vector plots, it facilitates rapid visualisation and segmentation of spectral contrast to classify sample features. As a proof of concept, a
