The problem of choosing error penalty parameter C for optimization extreme learning machine (OELM) is that it can take any positive value for different applications and it is therefore hard to choose correctly. In this paper, we reformulated OELM to take a new regularization parameter ν (ν-OELM) which is inspired by Schölkopf et al. The regularization in terms of ν is bounded between 0 and 1, and...
Ginning cotton qualities influence seriously the quality of textiles. Ginning cotton is always mixed with various defects during the picking, transporting, storing, and processing. This paper proposed one novel method to solve the problems of intensity changes of light source. Firstly, the properties of cotton and defects are studied. Secondly, the setup of measuring system is introduced and image...
To enhance the competitiveness of enterprises, the paper analyzes relations between the industrial cluster and competitive advantage. Taking wenzhou industrial cluster as the case, the paper discusses the factors that contribute to the success. The clustered industry and the competitive advantage are closely related and affected each other. Finally the paper puts forward solutions to enhance the competitiveness.
The use of 2-(4-biphenyl)-5-(4-butylphenyl)-1,3,4-oxadiazole (PBD) as an anode buffer layer in organic light-emitting devices (OLEDs) with a configuration of indum tin oxide/α-naphtylphenyliphenyl diamine/8-hydroxyquinoline aluminum/LiF/Al has been studied. With PBD buffer layer several angstroms thickness, the current efficiency increased and the stability of the device was improved. The results...
Organic light-emitting diodes (OLEDs) with a nanostructured TiO 2 layer at the interface between indium tin oxide and a-naphtylphenyliphenyl diamine layers were fabricated using a vacuum evaporation method. The nanostructured TiO 2 layer was achieved by the Sol-Gel method. Compared to the different thickness of the buffer layer, the OLEDs with the 6 nm buffer layer showed the highest...
