Business process modeling is the foundation of business process management (BPM). Recently, there are a large number of business process modeling approaches in BPM domain. Still, there are many differences in specific applications, due to the diversity of characteristics of the process environment and the features of business process modeling approaches. In this paper, we attempt to find the ad...

In this paper a comparative analysis of feature selection using typical testors applied on astronomical data, is presented. The comparison is based on the classification efficiency using typical testors as feature selection method against the classification efficiency using Ramirez (2001) method, which uses genetic algorithms. The well-known K-nearest neighbors rule (KNN) was used as classifier...

A survey was conducted of 157 Canadian Information Systems (IS) personnel in organizations throughout Canada using a modi®ed Delphi technique and follow-up interviews to identify the perceived critical issues in IS during the following 5 years. The important issues included: (1) building a responsive IT infrastructure; (2) improving IS project management practices and (3) planning and managing ...

The application of computer simulation as a research method raises two important questions: (1) Does simulation really offer added value over established methods? (2) How can the danger of arbitrariness caused by the extended modelling possibilities be minimised? We present the concept of stylised facts as a methodological basis for approaching these questions systematically. In particular, sty...

The present paper deals with numerical comparison of two twist-based severe plastic deformation processes: (i) the elliptical cross-section spiral equal-channel extrusion (ECSEE) proposed recently as a novel process and (ii) the classical twist extrusion (TE). ECSEE was developed in attempt to process cylindrical work pieces and to generate more uniform strain distribution compared to classical...

The article is devoted to a matrix method of comparative analysis of long nucleotide sequences by means of presenting each sequence in the form of three digital binary sequences. This method uses a set of symmetries of biochemical attributes of nucleotides. It also uses the possibility of presentation of every whole set of N-mers as one of the members of a Kronecker family of genetic matrices. ...

In this paper, we define a new cosine similarity between two interval valued neutrosophic sets based on Bhattacharya’s distance [19]. The notions of interval valued neutrosophic sets (IVNS, for short) will be used as vector representations in 3D-vector space. Based on the comparative analysis of the existing similarity measures for IVNS, we find that our proposed similarity measure is better an...

Regulatory compliance management (RCM) is a problem gaining wide interest in the business process management (BPM) community. However, research has not yet provided a non-ambiguous and agreedupon definition of RCM, and it is hard for newcomers to this field of research to get a clear overview of available results. This paper surveys and analyzes solutions proposed in research on RCM from the pe...

A national survey of 158 Canadian IS personnel at various organizational levels was conducted using a modiJed Delphi technique and follow-up interviews to ident@ the critical issues in information systems during the next three to five years. Critical information systems issues were identified including I) building a responsive IT injrastructure, 2) improving IS project management practices, and...

This paper presents an investigation on the undesirable vibration of an oblique-stud stator frame in a large hydropower generator by means of experimental and finite element (FE) analysis. First, field experimental tests were performed, and the results indicate that the main vibration component comes from electromagnetic factors. Then, a 2D-magnetic and 3D-mechanical FE model was developed to i...
