The study proposes a method for supervised classification of multi-channel surface electromyographic signals with the aim of controlling myoelectric prostheses. The representation space is based on the discrete wavelet transform (DWT) of each recorded EMG signal using unconstrained parameterization of the mother wavelet. The classification is performed with a support vector machine (SVM) approach in a multi-channel representation space. The mother wavelet is optimized with the criterion of minimum classification error, as estimated from the learning signal set. The method was applied to the classification of six hand movements with recording of the surface EMG from eight locations over the forearm. Misclassification rate in six subjects using the eight channels was (mean ± S.D.) 4.7 ± 3.7% with the proposed approach while it was 11.1 ± 10.0% without wavelet optimization (Daubechies wavelet). The DWT and SVM can be implemented with fast algorithms, thus, the method is suitable for real-time implementation. 相似文献

Rapid and efficient methods for determining the ability of soil and rhizosphere bacteria to produce key metabolites which are useful in growth promotion or suppression of plant growth are needed. A microplate method was developed and compared to a standard method for assays of auxin compounds produced by bacteria. The microplate method was similar to the standard method in accuracy of determination, required less chemical reagents, and considerably reduced the time required for analyses. 相似文献

H1t is a testis-specific H1 histone variant that appears in germ cells during the meiotic prophase of mammalian spermatogenesis. Using a tritiated antisense RNA probe, H1t mRNA was identified by in situ hybridization in the mid and late pachytene spermatocytes found in seminiferous tubules of approximately stages VII to XIII. 相似文献
