Scale‐robust fibre orientation analysis of hair using two‐dimensional Fourier transform

open access: yesInternational Journal of Cosmetic Science, EarlyView.
We present a simple and robust method to quantify hair fibre orientation using 2D‐DFT. It works with standard images and extracts directional features at multiple scales. This enables objective evaluation of cosmetic treatments and product effects. Abstract Objective To address the current lack of standardized tools for evaluating hair appearance in ...

An iterated greedy‐based metaheuristic with local search for the rank pricing problem

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The rank pricing problem involves determining optimal prices for a set of products while accounting for customers' budgets and preferences. This study develops an iterated greedy‐based metaheuristic to efficiently solve this problem. The core idea is to generate a sequence of solutions by iteratively applying destruction and reconstruction ...

Exact and metaheuristic approaches to minimizing makespan in parallel machine scheduling with conflicting jobs

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

An Improved PSO Algorithm and Its Application in GNSS Ambiguity Resolution

open access: yesApplied Sciences, 2018
In this study, we proposed a novel method for global navigation satellite system (GNSS) ambiguity resolution (AR). The proposed method utilizes an improved particle swarm optimization (IPSO) algorithm to obtain the GNSS integer ambiguity with the double ...

Leveraging modified ex situ tomography data for segmentation of in situ synchrotron X‐ray computed tomography

open access: yesJournal of Microscopy, EarlyView.
Abstract In situ synchrotron X‐ray computed tomography enables dynamic material studies. However, automated segmentation remains challenging due to complex imaging artefacts – like ring and cupping effects – and limited training data. We present a methodology for deep learning‐based segmentation by transforming high‐quality ex situ laboratory data to ...

Panel Sequential Group Estimation of Interactive Effects Models

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper proposes a novel procedure to identify latent groups in the slopes of panel data models with interactive effects. The method is straightforward to apply and relies only on closed‐form estimators when evaluating the objective function.

Threatened by the “Other”? Swiss Integration Policies and Citizens' Perceptions of Migrants Through the Lens of Reflective Solidarity

open access: yesSwiss Political Science Review, EarlyView.
Abstract Switzerland's federal structure offers a unique context to examine how cantonal integration policies shape citizens' perceptions of migrants. While research has linked integration policies and citizens' attitudes, it often neglects subnational variation.

The I in logic

open access: yesTheoria, EarlyView.
Abstract This paper argues for the significance of Kaplan's logic LD in two ways: first, by looking at how logic got along before we had LD, and second, by using it to bring out the similarity between David Hume's thesis that one cannot deduce claims about the future on the basis of premises only about the past, and the so‐called "essentiality" of the ...

Drawing Animals in the Paleolithic: The Effect of Perspective and Abbreviation on Animal Recognition and Aesthetic Appreciation

open access: yesTopics in Cognitive Science, EarlyView.
Abstract The majority of Pleistocene figurative cave art in Western Europe consists of line drawings depicting large herbivores from the side view, and outlines were sometimes abbreviated to the head‐neck‐dorsal line. It is often assumed that the side view was used because it facilitates animal recognition compared to other views, and that abbreviated ...
