APPLICATION OF ASYMMETRIC PROFILE IN GEARINGS WITH ECCENTRIC GEARS
Scientific Journal of Silesian University of Technology. Series Transport, 2014 Gearing was designed to meet specific requirement, during one rotation was continuous change of gear ratio. The gearing consists of two identical gears. The basic shape of the wheel is formed by an ellipse. One of the foci is the center of rotation. Wheels are designed for only one direction of rotation.

Prediction of Pipeline Defect Depth and Classification Based on CatBoost
Energy Science &Engineering, EarlyView.Obtaining detection data using in‐line pipeline inspection, the synthetic minority oversampling technique (SMOTE) is applied to expand the sample set, thereby increasing the number of minority‐class samples. This approach effectively improves minority‐class detection and enhances pipeline safety assessment. ABSTRACT Magnetic flux leakage detection is a

An analysis of fishing gear competition. Catalan fisheries as case studies
Scientia Marina, 2013 An asymmetric index was developed to measure the competition relationships among fishing fleets (or gears or métiers) in a multispecies fishery. This index can be used to measure the degree of dominance of each fleet and its level of independence from ...

Journal of International Development, EarlyView.ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Statistical analysis of variability properties of the Kepler blazar W2R 1926+42
, 2018 We analyzed Kepler light curves of the blazar W2R 1926+42 that provided nearly continuous coverage from quarter 11 through quarter 17 (589 days between 2011 and 2013) and examined some of their flux variability properties.

Bending strength simulation of asymmetric involute tooth gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015 Aiming at high load capacity, the design of the tooth profile which is not caught by the conventional profile is performed. Root stresses are calculated by 2D-FEM for various profile gears: 1) completely bilateral symmetry, 2) symmetry pressure angle and asymmetry fillet curve, and 3) asymmetry tooth.
