We examined the efficiency of the flux-gate magnetometers, MB-160 and MB-162, Shimadzu, which we use for variation observation at the Kakioka Magnetic Observatory. We also examined our method and the equipment for the calibration of the installed calibration apparatus in the flux-gate magnetometer. On the basis of examinations, we obtained the following conclusions: 1. Using our equipment for t...
Fat conic section and fat conic spline are defined. With well established properties of fat conic splines, the problem of approximating a ruled surface by a tangent smooth cone spline can then be changed as the problem of fitting a plane fat curve by a fat conic spline. Moreover, the fitting error between the ruled surface and the cone spline can be estimated explicitly via fat conic spline fit...
A first-order block-decomposition method for solving two-easy-block structured semidefinite programs
In this paper, we consider a first-order block-decomposition method for minimizing the sum of a convex differentiable function with Lipschitz continuous gradient, and two other proper closed convex (possibly, nonsmooth) functions with easily computable resolvents. The method presented contains two important ingredients from a computational point of view, namely: an adaptive choice of stepsize f...
In this paper, we consider a rst-order block-decomposition method for minimizing the sum of a convex di erentiable function with Lipschitz continuous gradient, and two other proper closed convex (possibly, nonsmooth) functions with easily computable resolvents. The method presented contains two important ingredients from a computational point of view, namely: an adaptive choice of stepsize for ...
As an illustration, consider the following two-step adsorption cycle to purify helium diving gas. Helium diving gas is principally a mixture of oxygen and helium, when the diving chambers are depressurised, the contaminated gas will consist mainly of carbon dioxide, oxygen and helium. Traditionally this waste gas has been thrown away. The PSA cycle described below is a method of purifying this ...
introduction: in this study the effects of low power helium-neon laser radiation on the cell population of open skin full thickness wound of rats were investigated from histological and biomechanical point of views. materials and methods: 90 male rats were randomly divided into control and two experimental groups. under general anesthesia and sterile conditions around open full thickness skin w...
the purpose of this study was to examine the status of supervision on departments’ heads at ferdowsi university of mashhad (fum) and realize some applied themes to provide a fit model for supervising departments’ heads in fum. the method was case study under a research category aimed for applied one. using purposive sampling, interviews were conducted with top fum managers, head departments, an...
