In allusion to the shortcomings of the existing signal analysis method for highfrequency analysis, non-stationary signal analysis and so on, wavelet analysis and grey theory are introduced into the signal analysis, a new signal analysis method based wavelet analysis and grey theory is proposed in this paper. In this method, the wavelet packet is used to nonredundantly, lossless and orthogonally...

Quality control in mammography is based upon subjective interpretation of the image quality of a test phantom. In order to suppress subjectivity due to the human observer, automated computer analysis of the Leeds TOR(MAM) test phantom is investigated. Texture analysis via grey-level co-occurrence matrices is used to detect structures in the test object. Scoring of the substructures in the phant...

Static program analysis complements traditional dynamic testing by discovering generic patterns and relations in source code, which indicate software deficiencies such as memory corruption, unexpected program behavior and memory leaks. Since static program analysis builds on approximations of a program’s concrete behavior there is often a trade-o↵ between reporting potential bugs that might be ...

Friction stir spot welding (FSSW) is a solid state method mainly used to join non-ferrous metals and their alloys. When opposed other processes, FSSW has the benefits of being pollution-free having no filler material. In this study an attempt was made for multi response optimization friction welded EN AW 5005 aluminum alloy using Taguchi Grey relational analysis (GRA). Pin height (h, mm), tool ...

In this paper, a compound binomial model with a constant dividend barrier and random income is considered. Two types of individual claims, main claims and byclaims, are defined, where every by-claim is induced by the main claim and may be delayed for one time period with a certain probability. The premium income is assumed to another binomial process to capture the uncertainty of the customer’s...

Let % denote a binary relation on a product set X = X1 × X2 × · · · × Xn. Conjoint measurement searches for conditions that allow numerical representations of % to be built and possibly guarantee the uniqueness of such representations. The interest of numerical representations is obvious. They not only facilitate the manipulation of preference relations but also, in many cases, the proofs that ...

Grey-markov forecasting model of traffic volume was founded by applying the model of GM (1,1) and Markov random process theory. The model utilizes the advantages of Grey-markov GM (1,1) forecasting model and Markov random process in order to discover the developing and varying tendency of the forecasting data sequences of traffic volume. The analysis of an example indicates that the grey-markov...

In machine learning, multiclass or multi-label classification is the special case within statistical classification of assigning one of several class labels to an input object. The multiclass problem is more complex than binary classification and less researched problem. In biology promoter is the DNA region where the transcription initiation takes place. Reliable recognition of promoter region...
