Service businesses have developed into an important economic force. Provision of various quality service products to more demanding customers is the key for organizations to retain a competitive advantage. Design is important for making such intangible products “visible” and manageable, and is considered as the key to service quality. A good understanding of the architectural aspects and a desi...

With Fq a finite field of characteristic p, let F(q) be the category whose objects are functors from finite dimensional Fq–vector spaces to F̄p– vector spaces. Extension groups in F(q) can be interpreted as MacLane (or Topological Hochschild) cohomology with twisted coefficients. Furthermore, evaluation on an m dimensional vector space Vm induces a homorphism from Ext F(q) (F, G) to finite group...

In this paper we explain how we teach generic programming to master students in computer science. Key concepts to transfer are the relation between plain types and their generic representation, kinds, and the function parameters corresponding to arrow kinds. We teach this successfully in three steps, we start with simple solutions, show why they fail and how a more sophisticated variant solves ...

This paper introduces four classes of rotation-invariant orthogonal moments by generalizing four existing moments that use harmonic functions in their radial kernels. Members of these classes share beneficial properties for image representation and pattern recognition like orthogonality and rotation-invariance. The kernel sets of these generic harmonic function-based moments are complete in the...

This paper presents a pre-processing and a distance which improve the performance of machine learning algorithms working on independent and identically distributed stochastic processes. We introduce a novel non-parametric approach to represent random variables which splits apart dependency and distribution without losing any information. We also propound an associated metric leveraging this rep...

We introduce a novel mixed characterword architecture to improve Chinese sentence representations, by utilizing rich semantic information of word internal structures. Our architecture uses two key strategies. The first is a mask gate on characters, learning the relation among characters in a word. The second is a maxpooling operation on words, adaptively finding the optimal mixture of the atomi...

Let π be a cuspidal generic representation of SO(2n + 1,A). We prove that L(12 , π) ≥ 0.

The present study aimed to investigate the generic organization of research article introductions in local Iranian and international journals in English for Specific Purposes, English for General Purposes, and Discourse Analysis. Overall, 120 published articles were selected from the established journals representing the above subdisciplines. Each subdiscipline was represented by 20 local and 2...
