چکیده
A novel minimization technique was developed. The proposed method is based on a Gaussian random search in the parameter space and it can handle wide range of problems, including bi-exponential curve fitting, reasonable time. It uses only function values, does not require gradients.

Adaptive Search Center Non-Linear Three Step Search
This paper presents a new motion estimation algorithm using an adaptive search center predicted from its adjacent blocks, and a non-linear center biased search point pattern. It does not have the problem of being trapped by local minimum, and is characterized by finding the majority motion vector in one step. When compared with six other block-based search algorithms including the full-search a...
متن کاملSpatially Adaptive Non-gaussian Imaging via Fitted Local Likelihood Technique
This paper offers a new technique for spatially adaptive Þltering. The Þtted local likelihood (FLL) statistics is proposed for selection of an adaptive size estimation neighborhood. The algorithm is developed for quite general observation models subject to the class of the exponential distributions. This algorithm shows a better performance than the intersection of conÞdence interval (ICI) algo...
متن کاملOlden Honored with Presidential Award
Tolerance of the lip mucosa of NMRI mice to single and fractionated irradiation combined with cis-diamminedichloroplatinum (II) (cis-DDP) was investigated. For the various combination schedules total drug doses varying from 6mgkg-1 to 13mgkg-1 were injected i.p. It was found that cis-DDP did not alter the radiation sensitivity of this tissue at any of the time intervals tested (ranging from 24 ...
متن کاملAdaptive Non-linear Filtering Technique for Image Restoration
Removing noise from the any processed images is very important. Noise should be removed in such a way that important information of image should be preserved. A decisionbased nonlinear algorithm for elimination of band lines, drop lines, mark, band lost and impulses in images is presented in this paper. The algorithm performs two simultaneous operations, namely, detection of corrupted pixels an...
متن کاملAdaptive fuzzy pole placement for stabilization of non-linear systems
A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...
