Effects of the Process Parameters on Austenitic Stainless Steel by TIG-Flux Welding

The effects of the process parameters of TIG （tungsten inset gas）-flux welding on the welds morphology, angular distortion, ferrite content and hot cracking in austenitic stainless steel were investigated. Autogenous TIG welding process was applied to the type 304 stainless steel through a thin layer of activating flux to produce a bead on plate welded joint. TiO2, SiO2, Fe2O3, Cr2O3, ZnO and MnO2 were used as the activating fluxes. The experimental results indicated that the TIG-flux welding can increase the weld depth/width ratio and reduce the HAZ （heat affected zone） range, and therefore the angular distortion of the weldment can be reduced. It was also found that the retained ferrite content within the TIG-flux welds is increased, and has a beneficial effect in reducing hot cracking tendency for stainless steels of the austenitic type weld metals. A plasma column constriction increases the current density at the anode spot and then a substantial increase in penetration of the TIG-flux welds can be obtained.     

Characterization of Gamma Irradiated Peanut Kernels Stored One Year Under Ambient and Frozen Conditions

Peanut kernels were gamma irradiated at 0, 2.5,5.0,10, and 20 KGy, and stored 1 yr at ambient and frozen (? 14°C) conditions. Irradiated peanuts lost germination capabilities during storage. Molds were detected only on peanuts irradiated with 2.5 KGy and stored at ambient temperature. Peanut oil in kernels stored at ? 14°C was comparatively more stable than that in peanuts stored at ambient temperature. Oxidation of oil was not significantly changed by irradiation. Changes in fatty acid content varied slightly with exception of linoleic and linolenic acids which decreased with increased radiation depending on storage temperature. The SDS-PAGE protein patterns of peanuts revealed no noticeable variation of protein subunits resulting from irradiation and storage.     

Trajectory sensitivity analysis using discrete Legendre orthogonal polynomials

A method of finite series expansion using discrete Legendre orthogonal polynomials (DLOPs) is applied to the problem of state trajectory sensitivity analysis. The method presented has a distinct advantage in that it reduces the problem of determining the trajectory sensitivity function to that of solving a set of algebraic equations. In addition, the method is simple and amenable to computer computation.     

Property Characterization of Peanut Kernels Subjected to Gamma Irradiation and Its Effect on the Outgrowth and Aflatoxin Production by Aspergillus parasiticus

Peanut kernels inoculated with Aspergillus parasiticus conidia and uninoculated kernels were gamma irradiated with 0 to 15 kGy using ⁶⁰Co. Levels of 2.5 and 5.0 KGy were effective in retarding the outgrowth of A. parasiticus and reducing the population of natural mold contaminants. However, elimination of these molds was not achieved. When irradiated with doses higher than 10 KGy, seed germinations were inhibited, changes in proteins were observed and oil stabilities decreased. After 4 wk incubation of the inoculated kernels in a humidified condition, aflatoxins produced by surviving A. parasiticus ranged from 69.12 to 13.48 μg/g depending upon the original irradiation dose.     

Analysis and identification of discrete-time systems via discrete Laguerre functions

This paper extends the application of discrete orthogonal Laguerre functions (DOLFs) to the analysis and parameter identification of linear time-invariant discrete-time systems described by difference equations with non-zero initial conditions. The extension is achieved through deriving a relationship between the DOLF expansion coefficients of a discrete function y(k + 1) and those of the delayed function y(k).     

Load Capacity for Adiabatic Finite-Width Plane Slider Bearings in the Turbulent Thermohydrodynamic Regime

A Navier-Stokes based model developed using the Legendre collocation method is used to analyze turbulent plane slider bearings with wide ranges of convergence ratio, slenderness ratio, mean Reynolds number, and a parameter characterizing the viscosity variation. The load-capacity formulations are established for turbulent isothermal and turbulent thermohydrodynamic bearings. With the equations provided in this study, designers can quickly determine the load capacity without extensive computation.     

Load Capacity for Adiabatic Infinitely Wide Plane Slider Bearings in the Turbulent Thermohydrodynamic Regime

A two-dimensional Navier-Stokes-based model developed using the Legendre collocation method is used to analyze turbulent plane slider bearings with wide ranges of bearing configuration, mean Reynolds number, and a parameter characterizing the viscosity variation. The load-capacity formulations are established for turbulent isothermal and turbulent thermohydrodynamic bearings. With the equations provided in this study, designers can quickly determine the load capacity without extensive computation.
