R. Kruzel, M. Suliga, Czestochowa University of Technology, Czestochowa, Poland Steel tire cord, springs and rope wires belong to the group of metal products from which the low residual stresses are required. In this paper the eff ect of multiple bending of wire on residual stresses of high carbon steel wires has been assessed. It was found that the application of the multi-roller straightening...

OBJECTIVE To evaluate a surgical technique used to straighten and support the crooked middle third of the nose. DESIGN Retrospective review of 41 patients with a markedly crooked nose who underwent correction using extended spreader grafts made from high-density porous polyethylene. Follow-up ranged from 6 months to 2 years. RESULTS Every patient had substantial improvement in the straighte...

A novel technique to generate three-dimensional Euclidean weavings, composed of close-packed, periodic arrays of one-dimensional fibres, is described. Some of these weavings are shown to dilate by simple shape changes of the constituent fibres (such as fibre straightening). The free volume within a chiral cubic example of a dilatant weaving, the ideal conformation of the G(129) weaving related ...

The use of phase change materials for buildings cooling is among the most investigated techniques to improve their energy efficiency. This paper presents experimental investigations a dual-stack latent thermal storage system applications in buildings. consists two PCM stacks placed parallel. Two main design configurations are based on flow straightening components installed before stacks. overa...

We introduce the notion of a straight tableau and prove that the straight tableaux of xed row-convex shape form a basis for the GL n -representations and the general linear Lie superalgebra representations associated to the given shape. We provide a straightening algorithm for expressing arbitrary tableaux in terms of straight tableaux. These techniques can be modi ed to provide bases for repre...

In this chapter, rotation angle estimation algorithms for textures and their real time implementations on a custom smart camera called FU-SmartCam is introduced (Ulas et al., 2007) and improved. In the textile industry, weft-straightening is a fundamental problem which is closely related to the rotation angle estimation. Earlier weft-straightening machines used simple sensors and hardware; howe...

An infrared-imaging system has been used to study the influence of gravity on the kinetics of first positive phototropism. The development of phototropic curvature of etiolated seedlings of Arabidopsis thaliana was measured in the absence of visible radiation. Following a pulse of blue light, stationary seedlings curved to a maximum of approximately 16 degrees about 80 minutes after stimulati...
