At present, the fruit picking in most countries still largely relies on manual operation. Manual fruit picking can protect the fruits from damage during the operation process. However, it is time-consuming and labor-intensive, and poses a potential safety risk to the workers while working at heights not reachable. Therefore, a variety of fruit picking machines and platforms have been developed ...
Background and aims: Despite automation, still many occupations require the use of hand tools in their routine activities. Scissors are essential tools for many workers in different occupations such as sewing and clothes making.The aim of this study was to investigate the effects of three re-designed models of sewing scissors (models A, B and C) on user performance, tool usability and hand and ...
If rock beats scissors and scissors beat paper, onemight assume that rock beats paper too. But this is not the case for intransitive relationships thatmake up the famous rock-paper-scissors game. However, the sole presence of papermight prevent rock frombeating scissors, simply because paper beats rock. This is the blueprint for the rock-paper-scissors gamewith protection spillovers, which has ...
In this work we focus on a natural class of population protocols whose dynamics are modelled by the discrete version of Lotka-Volterra equations. In such protocols, when an agent a of type (species) i interacts with an agent b of type (species) j with a as the initiator, then b’s type becomes i with probability Pij . In such an interaction, we think of a as the predator, b as the prey, and the ...
Introduction: Scissors are essential tools in different occupations including sewing and clothes making. Improper design of fabric cutting scissors can lead to the development of musculoskeletal symptoms among users. The aim of this study was to evaluate pinch force and wrist posture while working with three designs of sewing scissors and a traditional sewing scissors. Methods: The first model...
Preferential attachment networks are a type of random network where new nodes connected to existing ones at random, and more likely connect those that already have many connections. We investigate further family models introduced by Antunovi\'{c}, Mossel R\'{a}cz each vertex in preferential graph is assigned type, based on the types its neighbours. Instances this process proportions present do ...
Scissoring in thick bars suppresses buckling behavior in serpentine traces that have thicknesses greater than their widths, as detailed in a systematic set of analytical and experimental studies. Scissoring in thick copper traces enables elastic stretchability as large as ≈350%, corresponding to a sixfold improvement over previously reported values for thin geometries (≈60%).
[Purpose] The purpose of this study was to research the difference in wrist flexion and accuracy of left-handers when using regular scissors made for right-handed persons versus scissors made for left-handers. [Subjects and Methods] Eighteen left-handers participated in the experiment. There were ten males and eight females subjects. The degree of wrist flexion of 18 left-handers was analyzed w...
