Hybrid control with half-cycle adaptive switching rule and integral action for a Totem-Pole bridgeless rectifier

This paper proposes a hybrid control strategy for a single-phase Totem-Pole Bridgeless Rectifier (TPBR), modeled as an affine switched system combining controlled and autonomous dynamics under parametric uncertainties. The TPBR is analytically characterized as a current-dependent...

Two‐dimensional guillotine cutting problem for large objects with non‐rectangular shapes

Abstract In this paper, we address the two‐dimensional single large object placement problem with guillotine cutting constraints, focusing on non‐rectangular shapes. We consider objects with circular or convex polygonal geometries and study a variant that includes defective regio...

Regional assessment of atmospheric CO₂, CH₄ and CO concentrations in Southern Brazil using WRF-Chem under present and energy transition scenarios

Abstract The objective of this study was to evaluate the spatial and temporal distribution of greenhouse gases (CO₂ and CH₄) and the atmospheric pollutant CO in Santa Catarina, Brazil, and to analyze the impacts of energy transition scenarios on their atmospheric concentrations....

Evaluation of sludge from water and sewage treatment plants as a landfill cover layer

Abstract The management of sludge from water and sewage treatment plants (WTP and STP, respectively) is still a challenge due to its high complexity and high costs. In that regard, this research proposes to evaluate the potential of using sewage sludge and water sludge as cover m...

Integrating HAPS, LEO, and terrestrial networks: A cost-performance study for IoT connectivity

Background High-Altitude Platform Stations (HAPS) and Low Earth Orbit (LEO) satellites are emerging as alternative or complementary solutions for extending Internet of Things (IoT) connectivity, particularly in areas where terrestrial infrastructure is sparse, unavailable, or tem...

Prevalence of psychological distress among family caregivers of children with cancer: a systematic review and meta-analysis

Abstract Purpose: This study aimed to systematically review and quantify the prevalence of anxiety and depressive symptoms in family caregivers of children with cancer and to explore potential determinants that may influence these outcomes. Methods: This systematic review and met...

Demystifying the Lean 6.0 concept: integrating Industry 6.0 technologies with lean culture for innovation

Purpose This research paper aims to examine how companies are preparing to adopt Industry 6.0 (I6.0) and Lean Culture by identifying challenges, best practices, and the maturity of their integration with Knowledge Management (KM). It proposes the concept of Lean 6.0, which integr...

Small boundary: a family of linear-time greedy heuristics for the minimum linear arrangement problem

Abstract This paper addresses the minimum linear arrangement problem, a classical graph layout problem in which the objective is to minimize the sum of absolute differences between the labels assigned to adjacent vertices in undirected graphs. The paper introduces small boundary...

Learning Domains for Undergraduate Dental Behaviour Support: The BeSiDe Curriculum Learning Outcomes

OBJECTIVES: Dental Behaviour Support (DBS) refers to informal and formal strategies and interventions that support patients' acceptance and experience of oral healthcare. DBS plays a crucial role, particularly for vulnerable groups, yet training across dental curricula remains in...
