Abstract

Purpose

The present paper aims to present a numerical modeling of a train bogie following a railway accident in the Algerian railway which clearly showed the presence of cracks at the level of the bogie axles.

Design/methodology/approach

Our approach consists of making a numerical modeling in dynamic under variable load taking into account the reality of several parameters.

Findings

The aim is to present a predictive model allowing the identification of the probable causes that are the cause of this premature deterioration. We have determined the lifetime and the influence of frequency on railway axle. Also, the influence of overload on railway axle. The numerical model will be directed by Ansys software.

Originality/value

Our study allowed us to understand the mechanical behavior of a railway axle under several loadings, and to determine the critical value of the final failure to avoid damage.

Abstract

Management of information technology (IT) will continue to be an essential endeavour for organisations as we experience the increasing advancement of technology across different spectres of life. Managers will need to understand how technology is changing their business operations and the emergence of digital consumers who demand more innovative and technologically driven experiences. This book was conceptualised to provide theoretical insight for managers and researchers to understand where we are and where technology is taking us. This book has presented different chapters, highlighting management and practical implications across other technology, sector and countries. These selected chapters provide a wide variety of stimulating insights into the varying challenges and perspectives of management and IT in the digital era. Significantly, we recognise the growing prospects of Artificial intelligence (AI) and how it is revolutionising different sectors, further presenting critical challenges for managers on how to harness the opportunities of this technology for their business prospects.

Abstract

This study aims to study the reality and prospects of the digital economy in Algeria through annual reports and statistics that present the usefulness of digitalisation in Algerian economic sectors. Using an analytical study, we conclude that the economic sector had not experienced remarkable development in terms of digitalisation, except for a few activities in a few sectors such as health, industry and services that have experienced a gradual evolution to new information and communication technologies, which have brought added value in Algeria.
