We design an e cient algorithm for approximate pattern matching with grey scale values. The grey scale values range over interval [0;R] where R is a positive real number and the error bound for matching is measured by kR where k is a non-negative integer. Then we show that our algorithm solves this problem for the one-dimensional problem with O(kn logm=m) expected time, which is sublinear, wher...

the present study was carried out in 2011 to measure concentration of heavy metals chromium and tin in liver and muscle tissue of liza aurata (golden grey mullet) in estuaries of the rivers babolroud, tajan and gorganroud. accordingly, after sampling the target are asandisolating muscle (18samples) and liver (18samples) tissues, they were digested and analyzed using graphite furnace atomic abso...

Echinococcosis, which can seriously harm human health and animal husbandry production, has become an endemic in the Xinjiang Uygur Autonomous Region of China. In order to explore an effective human Echinococcosis forecasting model in Xinjiang, three grey models, namely, the traditional grey GM(1,1) model, the Grey-Periodic Extensional Combinatorial Model (PECGM(1,1)), and the Modified Grey Mode...

Abstract Although the grey forecasting model has been successfully utilized in many fields and demonstrated promising results, there are some problems in GM(1,1) model, such as, model method biased, transformation inconsistent and first number of the initial sequence not functioning high precision prediction in model after an accumulated generating operation. Literatures show its performance st...

In order to recover 3D-information from stereo image pairs, a number of stereo matching methods are available. These methods mainly differ in various tokens which are applied to solve the correspondence problem between left and right image. In most of the line segment based stereo matching algorithms, geometrical and structural information is used to estimate the correspondence. Unfortunately t...
