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...

Second order statistics of quaternion random variables and signals are revisited in order to exploit the complete second order statistical information available. The conditions for Q-proper (second order circular) random processes are presented, and to cater for the non-vanishing pseudocovariance of such processes, the use of ı-E-k-covariances is investigated. Next, the augmented statistics and...

Methods : In this prospective study conducted in a tertiary care public facility in New Delhi, India, PLHIV with chronic meningitis were screened for CM. A comparison of clinical assessment, Cerebrospinal fluid (CSF) analysis [cytology, biochemistry (sugar/protein), and microbiology (India ink staining/Latex Agglutination Test (LAT)], CSF and blood cultures and radiology (MRI brain) in 25 subje...

Predictions of cutting vibrations are necessary for improving the operational efficiency, product quality, and safety in the machining process, since the vibration is the main factor for resulting in machine faults. “Cutting vibration” may be caused by setting incorrect parameters before machining is commenced and may affect the precision of the machined work piece. This raises the need to have...

This paper reports the structural design of a new highperformance robot arm. Design objectives for the new arm include large (1-2 meter) workspace, low weight, 5 kg payload capacity, high sti ness, high structural vibration frequencies, precise joint-level torque control, a total of three degrees-offreedom, and mechanical simplicity. A comparative analysis is reported for four very di erent two...
