Introduction Foot movement in heel-toe running is influenced by various shoe lacing patterns [1]. Different shoe lacing systems and techniques also offer the possibility to improve shoe fit and shoe comfort. The purpose of this study was to investigate the effects of different lacing patterns on dorsal foot pressures during running. Furthermore, perceived comfort and shoe stability ratings were...

In this study, effects of lacing rods location on natural frequencies of last stage of a Steam Turbine Blades (STBs) have been investigated. STBs are critical and important elements in a turbine as well as power plants. One of the most important parameters in turbine blades is lacing rods location. In this paper, first, a three dimensional (3D) scan was used to produce the geometrical model of ...

We give four positive formulae for the (equioriented type A) quiver polynomials of Buch and Fulton [BF99]. All four formulae are combinatorial, in the sense that they are expressed in terms of combinatorial objects of certain types: Zelevinsky permutations, lacing diagrams, Young tableaux, and pipe dreams (also known as rc-graphs). Three of our formulae are multiplicity-free and geometric, mean...

Abstract Rehabilitation, upgrading, or strengthening of structural members, especially columns, has become the target many researchers because columns are most important members in a building and failure causes direct collapse building. This study aims to get an assessment best pattern steel-framed jacket used for axially loaded concrete by numerically studying behavior column different cases s...

The main theorem here is the K-theoretic analogue of the cohomological ‘stable double component formula’ for quiver polynomials in [KMS03]. This K-theoretic version is still in terms of lacing diagrams, but nonminimal diagrams contribute terms of higher degree. The motivating consequence is a conjecture of Buch on the sign-alternation of the coefficients appearing in his expansion of quiver K-p...

in iran, onion plants are currently broadcast over the majority of onion fields and weeding and harvesting are done manually by seasonal workers. at harvest time, 40 worker-days are required to onion dig just one hectare. this cost could be saved if the operation could be carried out by machine. rear-mounted diggers can only be implemented if 40 cm spacing between rows is allowed for each tract...
