Abstract:

Two guide bar warp knitted fabrics are used as technical textile applications nowadays. In this, Part III of these series of papers, models for basic two guide bar warp knitted fabrics are created and given based on Parts I and II. Modeling of warp knitted fabrics started in the 1960s with some basic geometrical models and it was continued with using Non Uniform Basis Spline (NURBS) curves and surfaces. There were discontinuities in the loop parts in early created geometrical models and the NURBS models needed some control points from some sources. In this work instead of using NURBS curves, m

Abstract:

Yarns of warp beams to knit on warp knitting machines need to be wound at equal tensions. The tension variations lead to produce valleys and ridges of warp yarns on the beam and hence different lengths of individual warp yarns. These length variations lead to loop length variations in warp knitted fabrics and may cause defects along the wales. This research aimed at investigating the warp length variations caused by tension variations and its effect on the quality of the fabrics knitted. Tension variations of individual warp yarns on warp beams for warp knitting were examined. 16% of warp yarn

Abstract:

The significant rise in the cost of manufacturing nanoscale integrated circuits (ICs) has led the majority of IC design companies to outsource the fabrication of their products to other companies, often located in different countries. The multinational nature of the hardware supply chain has led to a host of security threats, including IP piracy, IC overproduction, and Trojan insertion. To combat these, researchers have proposed logic locking techniques to protect the intellectual properties of the design and increase the difficulty of malicious modification of its functionality.

In the frequency domain, mode-locking of a laser is to "lock" the relative phase of various iongitudinal modes in order to form pulses. In many applications, passive mode-locking is superior to active mode-locking because the former does not need any external active sources as required for the latter. For passive mode-locking, we only need certain nonlinear effects to produce pulse compression mechanisms in laser systems. When the compression mechanism is balanced with some broadening effects, such as group-velocity dispersion, stable pulses can be obtained. In this paper, we first review seve

Abstract:

Comparing to the common locking mechanisms, this paper designs a new type of rope locking device which applies the wedge self-locking principle and hydraulic force-amplifying mechanism. The dynamic simulation research on the locking rope device with the usage of the ANSYS/IS-DYNA, and the simulation shows that the locking rope device can realize the self-lock of the first rope; the force-amplifying mechanism can effectively improve the security and stability of the rope locking, and reduce the abrasion of the first rope. Meanwhile, the simulation results provide a theoretical basis for the des

Abstract:

The locking plate fixations have been developed to enhance bone healing by wide bridging of the fracture and allowing some level of interfragmentary movement (IFM) at the fracture site. However, the IFM induced by conventional locking plate constructs is not uniform at the fracture site and so result in asymmetric callus formation, and ultimately delayed healing. The far cortical locking technique has been recently innovated to address this issue by inducing a uniform IFM. However, the far cortical locking technique is still in its infancy and more research efforts are required before its prac

Abstract:

The nomenclatorial history of the ichnogenera Lockeia and Pelecypodichnus has been confused by duality during the past 20 years. Many authors presume Pelecypodichnus is correct because Lockeia is a nomen oblitum. This presumption is rejected on both objective and subjective grounds. First, Lockeia is not a nomen oblitum. Two major gaps in the citational history of Lockeia exist, the first one of 35 years duration and the second of 43 years duration. Thus, no 50-year gap exists in the valid use of the name Lockeia. Second, the Committee on Zoological Nomenclature was not petitioned to declare L

We have compared the effect of locking and grasping suture loop configurations in four-strand core suture techniques for tendon repair. Forty canine flexor digitorum profundus tendons were repaired with one of four suture techniques (the grasping cruciate, the double-modified grasping Kessler, the locking cruciate and the double-modified locking Kessler) and tested to failure in a tensile testing machine. The mode of failure in all the locking suture specimens was breakage of the sutures in the locking loops or at suture knots. The sutures did not pull out of the tendon, as was seen in the gra

Abstract:

Locking function of a mechanism plays a significant role in safety and reliability. The operating principles of over-center locking in typical mechanisms and influencing factors of reliability to mechanism over-center locking were illustrated. A universal reliability analytical model of over-center locking mechanism was built and the algorithm of over-center angles was proposed. The result shows that in a planar four-bar mechanism, the dimension of driven link and variation coefficients have prominent influence on the reliability of over-center locking.

The present study was performed to test the null hypothesis on no difference in stability of fixation after volar plating of intra-articular distal radius fractures (AO C2-C3) with either locking smooth pegs or locking screws in a clinical setting. A retrospective evaluation included adult patients with C2-C3 AO fractures treated with a volar plate with locking smooth pegs or locking screws. Radiographic assessment was performed to evaluate extra- and intra-articular parameters in the early postoperative period and after bone union. Twenty-seven consecutive patients were included.

Abstract:

A short overview of different locking mechanisms is presented, in which the more recent locking phenomenon tension locking is placed. Tension locking is found during composite forming simulations and occurs when the element edges are unaligned with the fiber directions. Discontinuities in composite forming simulations show similarities with other weak discontinuities such as material interfaces and shear bands found during shear localization. Two enrichment strategies are explored to resolve tension locking in linear triangular elements.

Abstract:

Background: Recently, intramedullary headless screw (IMHS) has shown promise as an alternative to dorsal plate fixation of metacarpal fractures. The purpose of this study was to assess the biomechanical performance of IMHS versus plating. We hypothesized that IMHS fixation provides inferior stability to plating. Methods: Metacarpal fracture model with 3-mm of volar gapping in forty-four human cadaveric metacarpals was created. The specimens were divided into 5 groups: Group 1, 1.5-mm non-locking plate; Group 2, 1.5-mm locking plate; Group 3, 2.0-mm non-locking plate; Group 4, 2.0-mm locking pl

Abstract:

Standard finite elements can exhibit the numerical artifact of intra-plyshear locking during forming simulations. The displacement fields of elementsare piecewise continuous and cannot correctly capturediscontinuities in the shear field. This shear locking is illustrated insimulations of bias-extension experiments with an unaligned mesh. Two simpletests were developed as a critical indicator of intra-ply shear locking intriangular elements. A single-element-test shows the origin of the locking anda pull-out test indicates locking caused by small misalignments of theelements.

Abstract:

Strong stiffness provided by locking-plate system has resulted in nonunion and delayed union for long bone fracture. Longer bone plate can lengthen the working length to reduce the structural stiffness of the fixation device but will enlarge skin incision. Using the semi-rigid locking screw may be helpful but the efficacy was unclear. In simulated fracture model, four rigid locking screws were continually inserted beneath the fracture gap. The other four rigid/semi-rigid locking screws were equally distributed or concentrated at screw holes superior to the fracture gap. Axial compressive load
