Bottom-gate pentacene organic thin-film transistors (OTFTs) with HfLaO gate dielectric have been fabricated on different substrates with different gate materials (namely, Ti- or Al-coated vacuum tape, n-Si wafer, and ITO-coated glass) and the effects of the gate material on device performance have been studied. Although the dielectric surface and pentacene grain on the Ti- and Al-coated vacuum tapes...
This paper discusses specific contracts model for a three-stage service supply chain which consists of a service demander, service integration supplier and service suppliers with a contract service supplier and some temporary suppliers. The most important contribution on this paper is that it is proposed a joint contract of compensation and revenue sharing for the mathematical model which contains...
The feature of surface electromyography signal and the mechanism of wavelet analysis characteristic generated from massage technique were mainly researched, and then the relevant eigenvalues of the wavelet theory were extracted from the data of kneading method. The results showed that after analyzing the wavelet characteristics between the experts and the beginners, we could effectively distinguish...
Ascertainable clustering number is one of the vital problems of spectral clustering. To solve this problem, a spectral clustering algorithm automatically determining the clustering number is proposed. By mapping the sample point of the data set into feature space, the orthogonal positional relationship of sample points between different clusters in the feature space can be determined. Based on the...
Based on the systematic research in contents, methods and technology of the international S&T resources, the article established the visual monitoring & service system of international S&T resources, proposed the “three first-classes” concept of international S&T resources. For different types of international science and technology information databases, by use of scientometrics,...
Firstly, the Khinchine law of large numbers based on the rough fuzzy samples is given. Secondly, based on the rough fuzzy samples, some concepts such as rough fuzzy expected risk functional, rough fuzzy empirical risk functional and rough fuzzy empirical risk minimization principle are proposed. Finally, the key theorem of learning theory based on the rough fuzzy sample is proved.
Construction programme, which internal and external environment is complicated, is a group composed of numerous interrelated projects, thus the uncertainty of risk is more evident. In order to ascertain the integrity and the certainty of information relatively, which lead to more scientific and the advisable evaluation, the programme is divided into subgroups in paper first. Then an analysis of the...
