Identifying the Slider Crank Mechanism System by the MPSO Method

open access: yes, 2018
This paper mainly proposes an efficient modified particle swarm optimization MPSO method, to identify a slider crank mechanism driven by a field oriented PM synchronous motor, dynamic formulations of a slider crank mechanism have been successfully ...

Swinging double slider-crank

open access: yes, 2011
The double slider-crank mechanism was an early method for drawing ellipses. Two prongs of a fixed metal bar slide freely in two perpendicular slots. The bar has an extension that can be locked down.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

open access: yesCladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Geometric design of slider-crank mechanisms for desirable slider positions and velocities

open access: yes, 2011
In problems requiring uniform cutting speeds uniform flow rates etc. slider-crank mechanisms provide economical solutions. Thus, the problem of designing slider-crank mechanisms for desirable slider positions and velocities is handled within a geometric ...

Kinematics Analysis of Multi-link Mechanism for Miniature Servo Press Based on Matlab

open access: yesMATEC Web of Conferences, 2018
The degree of freedom for a multi-link drive mechanism of a 50kN miniature servo press was calculated. The kinematics equations of the mechanism was established based on the rod group method.

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

Analytical and Experimental Investigation of Elastic Slider-Crank Mechanisms

open access: yes, 1976
Analytical and experimental dynamic bending stresses are determined for a slider-crank mechanism with a rigid crank and an elastic connecting rod. The mathematical model is derived by way of the lumped-parameter approach using d’Alembert’s principle and ...
