In this paper we propose a numerical reconstruction method for solving a backward heat conduction problem. Based on the idea
of reproducing kernel approximation, we reconstruct the unknown initial heat distribution from a finite set of scattered measurement
of transient temperature at a fixed final time. Standard Tikhonov regularization technique using the norm of reproducing kernel
is adopt to provide a stable solution when the measurement data contain noises. Numerical results indicate that the proposed
method is stable, efficient, and accurate. 相似文献

The front cover artwork is provided by the group of Prof. Hiroaki Misawa (Hokkaido University, Japan, and National Chiao Tung University, Taiwan). The image shows a plasmon‐induced water‐splitting system, which can collect hydrogen and oxygen separately and employs a semiconductor substrate.

We have demonstrated that prenylation of p-halophenols was dependent on the solvent effect and succeeded in o,o'-diprenylation of p-halophenols in water. Following the Mizoroki-Heck coupling of the diprenyl-p-iodophenol 3c with methyl acrylate and then hydrolysis, we first synthesized artepillin C [3-(4-hydroxy-3,5-di(3-methyl-2-butenyl)phenyl)-2(E)-propenoic acid] (1), which is a biologically active constituent of propolis. These reactions may be applicable to the synthesis of various useful natural products such as 2,4,6-trisubstituted phenol derivatives. 相似文献

This paper is concerned with the analysis of dynamic deflection and acceleration of a concrete bridge which is subjected to a moving vehicle load. The bridge, to be constructed across the River Brahmaputra in India, consists of 20 main spans, and each main span is assumed to be double cantilever type with a small suspended span. The moving vehicle is modeled as one degree of freedom. The deflections and accelerations at specific locations on the bridge when the vehicle moves at constant speed are analyzed by using the finite element method. 相似文献

Summary Some organic acids, alcohol and amine which have an asymmetric carbon atom were used for an investigation of asymmetric absorption
on wool. Racemic mixture of hydratropic acid, mandelic acid andα-phenethylamine have shown the selective absorption on wool from their aqueous and alcoholic aqueous solutions and S-form
of their diastereoisomers preferentially absorbed on wool. According to the results we obtained so far, it is concluded that
the preferential absorption strongly depends on the configuration of the substance of which wool is composed. 相似文献

The splitting of trajectories with non-vacuum quantum numbers is discussed within the dual unitarisation scheme. The estimated difference in intercepts between vector-tensor trajectories of opposite signatures, such as ? ? A2 and , agrees both in sign and magnitude with that deduced from phenomenological analyses. 相似文献
