Compressibility Behaviour Of Warp Knitted Spacer Fabrics Based On Elastic Curved Bar Theory, Fatemeh Mokhtari, Mahnaz Shamshirsaz, Masoud Latifi, Mohammad Maroufi

Faculty of Engineering and Information Sciences - Papers: Part B

Nowadays, the mechanical characterization of 3-D spacer fabrics has attracted the interest of many textile researchers. These Spacer fabrics present special mechanical and physical characteristics compared to conventional textiles due to their wonderful porous 3-D structures. These fabrics, produced by warp knitting method, have extensive application in automobile, locomotive, aerospace, building and other industries. In these applications, the compressibility behaviour plays a significant role in the fabric structural stability. This compressibility behaviour could be affected by different knitting parameters such as density of pile yarn, fabric thickness, texture design etc.

The aim of this paper is to introduce and develop …

A Comparative Study Of Three Inverse Kinematic Methods Of Serial Industrial Robot Manipulators In The Screw Theory Framework, Emre Sariyildiz, Eray Cakiray, Hakan Temeltas

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper, we compare three inverse kinematic formulation methods for the serial industrial robot manipulators. All formulation methods are based on screw theory. Screw theory is an effective way to establish a global description of rigid body and avoids singularities due to the use of the local coordinates. In these three formulation methods, the first one is based on quaternion algebra, the second one is based on dual-quaternions, and the last one that is called exponential mapping method is based on matrix algebra. Compared with the matrix algebra, quaternion algebra based solutions are more computationally efficient and they need …

The Development And Manufacture Of Ultra-Thin Cast Strip Steel Products With High Residual Element Levels Via The Castrip® Process, Daniel G. Edelman, Peter C. Campbell, Chris R. Killmore, Kristin R. Carpenter, Harold R. Kaul, James G. Williams, Walter N. Blejde

Faculty of Engineering and Information Sciences - Papers: Part B

A range of Ultra-Thin Cast Strip (UCS) sheet steels with elevated residual levels was produced via the CASTRIP twin drum casting method at Nucor Steel, Indiana. This paper examines the influence of elevated levels of copper, chromium, nickel, and phosphorous on mechanical properties, surface quality, processing, and weldability of UCS sheet steel products produced by the CASTRIP process. Increased levels of copper and phosphorous were found to strengthen UCS sheet steel due to solid solution strengthening but chromium and nickel did not. At lower coiling temperatures and low hot reductions, where processing conditions promote microstructural strengthening, copper and chromium further …

Parametric Investigation Of Near End And Far End Crosstalks In Printed Circuit Board Lands, Md Masud Rana, Md Rabiul Islam, Md Kamal Hosain

Faculty of Engineering and Information Sciences - Papers: Part B

Multi-conductor transmission line and interconnect carry signals with wide rage of frequencies from sending end to receiving end. The signal in one transmission line may be interupted by the unwanted contributions from the neighboring line conductors. If data speed increases, high frequency effects occur and the signals suffer from difficulties such as ringing, crosstalk, reflections, and ground bounce that seriously hamper the quality of the received signal. In order to estimate the signal quality, signal integrity analysis is needed. In this paper, an attempt has been made to investigate the sensitivity of the near and far end crosstalk on the …
