Hybrid system of expert system and artificial neural networks for objective evaluation of product sensuous quality

Basic problems and the bottleneck of current approaches for objective assessment of product sensuous quality (PSQ) are discussed. As a solution, a new approach, an expert system (ES) based on artificial neural networks (ANNs) is proposed, in which the ES and ANNs co-operate in a superiority compensation way. T he knowledge base of the system can be effectively built and the evaluation of PSQ can be conducted on-line. As a case study, the new approach has been applied in leather handle test and it proves that the approach is capable of handling non-linear relationships among multiple measured PSQ parameters

Classification of Harish-Chandra Modules over the Higher Rank Virasoro Algebras

It is obtained that an irreducible weight module with finite weight multiplicities over a higher rank Virasoro or super-Virasoro algebra is either a module of the intermediate series, or a so-called finitely-dense module.Comment: Some errors in Theorems 1.1 and 1.2 are correcte

Coding Subset Shift by Subgroup Conjugacy

We present a Borel reduction from a subset shift equivalence relation of a countable group to a subgroup conjugacy relation of a free product. The technique gives a much shorter proof of an earlier result of Thomas and Velickovic

Generalizations of local bijectivity of Keller maps and a proof of 22-dimensional Jacobian conjecture

We give a proof of two-dimensional Jacobian conjecture.Comment: This FINAL version is prepared based on the author's two days' lectures (on May 22, 2022 and May 29,2022; the video of the lectures can be found at https://m.koushare.com/video/videodetail/27869

‘You don’t need influence … all you need is your first opportunity!’: The Early Broadcast Talent Show and the BBC

Popular histories of the reality talent show often position programmes like Opportunity Knocks as key generic precursors to the popular formats of today. But the visibility of such shows in such popular histories - and in popular memory - disguises the fact that the genre has been almost totally neglected in both television historiography and celebrity studies. In drawing upon archival documentation, this article looks at early examples of the broadcast talent show in Britain, with a particular focus on radio’s Opportunity Knocks, and examines the institutional and cultural discourses which surrounded them
