    Notes: : Ground pork patties were processed from pork hams to achieve fat levels of 5%, 10%, 15%, 20%, and 25%. Each patty was cooked in a microwave oven to 75 °C from a thawed state. As fat levels increased, cooking time decreased. Total cooking loss and drip loss were highest for 25% fat patties and lowest for 5% fat patties. High-fat patties (20% and 25%) had greater reductions in dia than did 5% to 15% fat patties, but had less change in patty thickness. Shear force values decreased as fat levels increased. Visual evaluations also indicated a greater presence of air pockets in high-fat patties. In raw patties, low-fat samples were darker (had lower L* values) and were redder (had higher a* values) than patties with more fat. However, these differences were relatively smaller when the patties were cooked. As fat levels increased, flavor, tenderness, juiciness, and oiliness ratings increased. These differences were not as apparent when comparing among low-fat patties or high-fat patties. Keyword: microwave, cooking, fat, pork patty

    Notes: Reactions between 48Sn-52In solder and under bump metallurgies(UBM) such as 100nmTi/8µm Cu and 300nm Al/400nm Ni(V)/400nm Cu have been investigated, and the shear strength of 48Sn-52In solder bumps on each UBM has been evaluated. While intermetallic compounds with two different morphologies were continuously thickened on Ti/Cu with repeating the reflow process, the intermetallics on Al/Ni(V)/Cu spalled into the solder with increasing the number of reflow times.The solder bumps on Ti/Cu exhibited higher shear strength than those on Al/Ni(V)/Cu

    Notes: Ferroelectric characteristics of the 400 nm-thick Sr〈sub〉x〈/sub〉Bi〈sub〉2.4〈/sub〉Ta〈sub〉2〈/sub〉O〈sub〉9〈/sub〉(0.7≤x≤1.3) thin films processed by metalorganic decomposition were investigated, and electrical properties of the Pt/Sr〈sub〉0.85〈/sub〉Bi〈sub〉2.4〈/sub〉Ta〈sub〉2〈/sub〉O〈sub〉9〈/sub〉/TiO〈sub〉2〈/sub〉/Si structure prepared using TiO〈sub〉2〈/sub〉 buffer layer were characterized. The Sr-deficient Sr〈sub〉x〈/sub〉Bi〈sub〉2.4〈/sub〉Ta〈sub〉2〈/sub〉O〈sub〉9〈/sub〉 films exhibited well-developed ferroelectric hysteresis curves compared to those of the Sr-excess films. The Sr0.85Bi2.4Ta2O9 film exhibited optimum ferroelectric properties, such as high remanent polarization and low leakage current density, among Sr〈sub〉x〈/sub〉Bi〈sub〉2.4〈/sub〉Ta〈sub〉2〈/sub〉O〈sub〉9〈/sub〉 films. A memory window of the Pt/SrxBi2.4Ta2O9/TiO2/Si structure was dependent upon the coercive field of the Sr〈sub〉x〈/sub〉Bi〈sub〉2.4〈/sub〉Ta〈sub〉2〈/sub〉O〈sub〉9〈/sub〉 film, and the Pt/Sr〈sub〉x〈/sub〉Bi〈sub〉2.4〈/sub〉Ta〈sub〉2〈/sub〉O〈sub〉9〈/sub〉/TiO〈sub〉2〈/sub〉/Si exhibited a maximum memory window of 1.3 V at the sweeping voltage of ±5 V

    Notes: The numerical prediction of the effective mechanical properties of the reinforced braid inserted in automobile power steering hose is addressed. The key role of the reinforced braid layer is to suppress the excessive radial expansion of the hose subject to high pressure and temperature. The reinforced braid layer is in the structure composed of wrap and fill tows inclined to each with the specific helix angle. In order to predict the effective mechanical properties, we construct a 3-Dfinite element model of the unit cell (or RVE) of the reinforced braid in a periodic pattern, in which the detailed geometry of individual fiber tows is fully modeled. By making use of the superposition method and the 3-D finite element analysis, the effective mechanical properties are predicted. Numerical experiments illustrating the theoretical work are also presented

    Notes: Abstract A three-dimensional computational finite element procedure for the vibration and dynamic stress analysis of the track link chains of off-road vehicles is presented in this paper. The numerical procedure developed in this investigation integrates classical constrained multibody dynamics methods with finite element capabilities. The nonlinear equations of motion of the three-dimensional tracked vehicle model in which the track link s are considered flexible bodies, are obtained using the floating frame of reference formulation. Three-dimensional contact force models are used to describe the interaction of the track chain links with the vehicle components and the ground. The dynamic equations of motion are first presented in terms of a coupled set of reference and elastic coordinates of the track links. Assuming that the structural flexibility of the track links does not have a significant effect on their overall rigid body motion as well as the vehicle dynamics, a partially linearized set of differential equations of motion of the track links is obtained. The equations associated with the rigid body motion are used to predict the generalized contact, inertia, and constraint forces associated with the deformation degrees of freedom of the track links. These forces are introduced to the track link flexibility equations which are used to calculate the deformations of the links resulting from the vehicle motion. A detailed three-dimensional finite element model of the track link is developed and utilized to predict the natural frequencies and mode shapes. The terms that represent the rigid body inertia, centrifugal and Coriolis forces in the equations of motion associated with the elastic coordinates of the track link are described in detail. A computational procedure for determining the generalized constraint forces associated with the elastic coordinates of the deformable chain links is presented. The finite element model is then used to determine the deformations of the track links resulting from the contact, inertia, and constraint forces. The results of the dynamic stress analysis of the track links are presented and the differences between these results and the results obtained by using the static stress analysis are demonstrated.

    Notes: Abstract A convenient implementation method for constrained flexiblemultibody dynamics is presented by introducing a virtual rigid body andjoint. The general purpose program for rigid and flexible multibodydynamics consists of three major parts of a set of inertia modules, aset of force modules, and a set of joint modules. Whenever a new forceor joint module is added to the general purpose program, the modules forthe rigid body dynamics are not reusable for the flexible body dynamics.Consequently, the corresponding modules for the flexible body dynamicsmust be formulated and programmed again. Since the flexible bodydynamics handles more degrees of freedom than the rigid body dynamicsdoes, implementation of the module is generally complicated and prone tocoding mistakes. In order to overcome these difficulties, a virtualrigid body is introduced at every joint and force reference frames. Newkinematic admissibility conditions are imposed on two-body referenceframes of virtual and original bodies by introducing a virtual flexiblebody joint. There are some computational overheads due to the additionalbodies and joints. However, since computation time is mainly dependenton the frequency of flexible body dynamics, the computational overheadof the presented method is not a critical problem, while implementationconvenience is dramatically improved.
