Novel adaptation of the demodulation technology for gear damage detection to variable amplitudes of mesh harmonics [PDF]

open access: yes, 2011
In this paper, a novel adaptive demodulation technique including a new diagnostic feature is proposed for gear diagnosis in conditions of variable amplitudes of the mesh harmonics.

Sloppy gear mechanism for coupled stochastic transportation: From antiequilibrium flow to kinetic selectivity

open access: yesPhysical Review Research, 2022
Nonequilibrium transportation of particles through a restricted space (such as porous media or narrow channels) significantly differs from free space. With a simple model of two types of particles competing to transport via a passive single-lane channel ...

Circling the Archetype: Tensions Limiting the Transformation to a Circular Economy

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This research examines key tensions and the archetypal paradox that prevent the transformation to a circular economy (CE) across individual, organizational, and systems levels, problematizing CE assumptions. Tension manifestations are analyzed using a qualitative case study across eight diverse industries and geographies.

Mathematical models of gear rattle in Roots blower vacuum pumps [PDF]

open access: yes, 2006
This paper is concerned with the modelling of gear rattle in Roots blower vacuum pumps. Analysis of experimental data reveals that the source of the noise and vibration problem is the backlash nonlinearity due to gear teeth losing and re-establishing ...

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids

open access: yesChemistry – A European Journal, EarlyView.
This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

Aligning Fishing Gear Selectivity With Harvest Slot Limits for Ballan Wrasse Labrus bergylta

open access: yesAquaculture, Fish and Fisheries
Selectivity is an important parameter used to identify the portion of a stock caught by a fishing gear. In principle, fisheries management aligns the length at which 50% of individuals are selected for (L50) with minimum landing sizes.

Evaluation of Pervaporation and Nanofiltration Membranes for Water Recovery From Thermo‐Responsive Draw Solution

open access: yesChemie Ingenieur Technik, EarlyView.
Integrating thermo‐responsive draw solutions with suitable water‐recovery technologies could enable more efficient hybrid desalination. This study compares pervaporation and nanofiltration, revealing key trade‐offs between water productivity and polymer retention and providing guidance for future FO‐based brine treatment systems.

Sustainable Business Model Innovation and Firm's Performance: A Multiple Case Study in the Agri‐Food Industry

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This research investigates how sustainability‐oriented initiatives aimed at innovating a firm's business model can lead to different economic, social and environmental performance configurations, with the objective of identifying the determinants that explain these differences. We carried out a multiple case study, selecting firms based on the

Kinematic analysis of complex gear mechanisms [PDF]

open access: yes, 2010
This paper presents a general kinematic analysis method for complex gear mechanisms. This approach involves the null-space of the adjacency matrix associated with the graph of the mechanism weighted by complex coecients.
