Multimodal surface defect detection from wooden logs for sawing optimization

We propose a novel, cost-effective method for knot detection on the surface of wooden logs using multimodal data fusion. Knots are a primary factor affecting the quality of sawn timber, making their detection fundamental to any timber grading or cutting optimization system. Howev...

Climate benefits of Power-to-X pathways utilizing green hydrogen – A contradiction of regional and international emission savings

Abstract Renewable Power-to-X solutions can provide extensive emission savings by replacing fossil feedstocks directly in the producing country or through exports. This study is based on the hypothesis that different PtX pathways contribute to emission savings in varying amounts....

CFD-based multi-objective optimization of operating conditions in a small-scale ORC radial-inflow turbine using response surface methodology

This study presents a CFD–RSM framework for constructing surrogate-based operating maps and optimizing the operating conditions of a manufactured small-scale radial-inflow turbine used in an Organic Rankine Cycle (ORC) system. Unlike studies focused mainly on turbine redesign, th...

A systematic review of mathematical models for soil-transmitted helminthiasis control strategies

Background Soil-transmitted helminthiasis (STH) remains an important public health challenge in endemic settings, and mathematical transmission models are widely used to evaluate STH transmission and control strategies. However, no systematic review has comprehensively classified...

The Role of Advanced Technologies in Corporate Decarbonization: A Problematizing Review and Comparative Research Agenda

Abstract Advanced technologies are widely promoted as tools for decarbonization across sectors such as manufacturing, logistics, and energy. However, evidence of their environmental impact remains mixed, with outcomes varying significantly between settings. This variability highl...
