BACKGROUND The Chinese fauna of Pteroptrix currently includes 26 species, of wihich 19 species were described originally as new from China: 2 by Howard (1907), 2 by Compere (1953), 1 by Flanders (1966), 1 by Viggiani and Ren (1986), 4 by Huang (1991), 4 by Huang et al. (1992), 1 by Viggiani and Ren (1993), 4 by Huang (1994). NEW INFORMATION Pteroptrix pedicellatasp. n. is described in detail ...

The Empirical Mode Decomposition (EMD) is a popular algorithm used for the processing of non-linear and non-stationary signals. In this paper we implemented the EMD algorithm and study the use of EMD in broad range of applications for extracting data from the signals. It decomposes the signal into highly varying Intrinsic Mode Functions (IMF) and slowly varying residues. Finally the results are...

Huang’s data-driven technique of Empirical Mode Decomposition (EMD) is presented, and issues related to its effective implementation are discussed. A number of algorithmic variations, including new stopping criteria and an on-line version of the algorithm, are proposed. Numerical simulations are used for empirically assessing performance elements related to tone identification and separation. T...

This paper is focused on the segmentation of the fabric weave patterns for the urgent requirement of fabric imitative design and redesign.The weave patterns related to the fabric yarn are determined by a new technology, which is called bidimensional mode decomposition based method. The proposed method first iteratively decompose the underlying fabric image into a number of intrinsic mode functi...

Marine Engineering faces certain challenges in recent times due to the prevalence of ambient conditions caused by imbalance in the ecosystem. Underwater ambient noise is primarily a background noise, which is a function of time, location and depth. It is of prime importance to detect the signals such as the sound of a submarine or an echo from a target, surpassing and surmounting this ambient n...

In this paper, a hybrid method for occlusion removal using Finite element based Bi-dimensional Empirical Mode Decomposition (FE-BEMD) and Exemplar based image inpainting is discussed. Initially, the image is decomposed into Intrinsic Mode Functions (IMFs) and a Residue using FEBEMD. Then the Exemplar based image inpainting algorithm is applied to each of the IMFs and residue and the results are...

A taxonomic review of 23 species of the subgenus Pseudoophonus Motschulsky, 1844, the genus Harpalus Latreille, 1802, occurring in China is given, and a key to these species is provided. The species are divided in three species groups and five subgroups, the distinctive characters of which are listed. The following new synonyms are established: Harpalus calceatus Duftschmid, 1812 = Anisodactylu...

Classified stable matching, proposed by Huang, describes a matching model between academic institutes and applicants, where each institute has upper and lower quotas on classes, i.e., subsets of applicants. Huang showed that the problem to decide whether there exists a stable matching or not is NP-hard in general. On the other hand, he showed that the problem is solvable if the classes form a l...

This letter is a response to the comments of Serang (2012) on Huang and He (2012) in Bioinformatics. Serang (2012) claimed that the parameters for the Fido algorithm should be specified using the grid search method in Serang et al. (2010) so as to generate a deserved accuracy in performance comparison. It seems that it is an argument on parameter tuning. However, it is indeed the issue of how t...

For non-stationary signal in ultrasonic inspection, an effective denoising method based on Hilbert-Huang transform (HHT) is presented and a few key questions using the HHT method are discussed. The overall scheme of HHT includes two parts which are empirical mode decomposition (EMD) algorithm and a sum of intrinsic mode functions (IMF). Through the EMD process, individual IMF can be found. The ...
