Abstract

Examines the seventeenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

Purpose

To study the mathematical image coding approaches used in two types of biometric systems, and the physical nature of those biometrics.

Design/methodology/approach

Gives details of algorithms used to encode data from images in established and new automatic iris recognition systems. Then examines face recognition techniques based on geometry, texture and three‐dimensional data.

Findings

Most commercial iris recognition systems are based on the algorithms developed by one man, John Daugman. Whilst iris systems can be used to check a person's identity against a large database of enrolled people, face recognition systems are currently only capable of use in one‐to‐one recognition mode, or in identification mode against a very small database. The iris is very distinctive and stable over time, but the face is much more variable and therefore difficult to identify with accuracy.

Originality/value

Provides the general scientific reader with some insight into the specialised field of biometric recognition.

Abstract

Purpose

The purpose of this paper is to conduct a review of types of tomographic systems that have been widely researched within the past 10 years. Decades of research on non-invasively and non-intrusively visualizing and monitoring gas-liquid multi-phase flow in process plants in making sure that the industrial system has high quality control. Process tomography is a developing measurement technology for industrial flow visualization.

Design/methodology/approach

A review of types of tomographic systems that have been widely researched especially in the application of gas-liquid flow within the past 10 years was conducted. The sensor system operating fundamentals and assessment of each tomography technology are discussed and explained in detail.

Findings

Potential future research on gas-liquid flow in a conducting vessel using ultrasonic tomography sensor system is addressed.

Originality/value

The authors would like to undertake that the above-mentioned manuscript is original, has not been published elsewhere, accepted for publication elsewhere or under editorial review for publication elsewhere and that my Institute’s Universiti Teknologi Malaysia representative is fully aware of this submission.

Abstract

Purpose

The flexible eddy current array sensor has the characteristics of lightweight and flexibility, which has a great application prospect in the field of fatigue crack monitoring. But the exciting layout and feature signal extraction have a great influence on the crack monitoring characteristics of the sensor. This paper aims to propose a method using crack disturbed voltage as sensitivity to characterize crack propagation.

Design/methodology/approach

Flexible eddy current array sensors with reverse and codirectional exciting layout are proposed, and the advantages and disadvantages of three characterization methods based on the change of trans-impedance amplitude, the change of the trans-impedance’s real and imaginary part and the crack disturbed voltage are compared and analyzed by finite element simulation. Finally, the fatigue crack monitoring experiment is carried out.

Findings

The crack disturbed voltage and the change of trans-impedance’s imaginary part can effectively characterize the crack propagation for sensors with different exciting layouts. The codirectional exciting layout sensor has better crack identification sensitivity than the reverse exciting layout sensor, especially the induction coil 2. When the distance between the exciting coil and the induction coil is 0.1, 0.2 and 0.3 mm, it is increased by 372.09%, 295.24% and 231.43%, respectively.

Originality/value

Crack disturbed voltage can effectively characterize the crack propagation for sensors with two different exciting layouts.

Abstract

Purpose

The purpose of this paper is to review the most recent innovations in sensor technology for better quality in packaging. Checking for container seals, damaged product, contaminates as well as tracking product to meet government requirements.

Design/methodology/approach

In-depth interviews with both the exhibitors and integrators of sensors at the recent PackExpo show.

Findings

Sensor technology continues to address an ever increasing number of packaging applications including quality, safety, product tracking, correct labeling as well as counting, weighing and other more traditional applications.

Practical implications

Sensor technology advances with greater use of X-ray, magnetic detection and remote chemical monitoring that are addressing an ever increasing number of packaging applications including quality, safety as well as counting, weighing and other more traditional applications.

Originality/value

Customers will learn about the latest in X-ray, magnetic sensing and the application of vision, weighing and counting technologies for improved products as they pass through the packaging phase of production.

Abstract

Purpose

The study, which compares the success factors for eco‐innovations with those factors for other innovations, is intended to improve understanding of how eco‐innovations achieve market success.

Design/methodology/approach

A case study design is used. Six eco‐innovations cases and six other innovations cases are compared. Data were obtained mainly from interviews with the eco‐innovators and the other innovators, written materials about the innovations, and secondary data from an earlier quantitative study.

Findings

The study shows that there are both similarities and differences in the success factors for the two types of innovations. One similarity is that a network with diverse competences supports successful innovators. However, for eco‐innovators the network is used more for solving technological problems. Other innovators use the network to a greater extent for assistance with financing and marketing. In addition, eco‐innovators have greater difficulty than other innovators in attracting venture capital for development.

Research limitations/implications

The results indicate that an interesting approach for future research would be to take a life‐cycle perspective that identifies the factors that influence the further growth and development of eco‐innovative firms.

Practical implications

The identification of the success factors for eco‐innovations' development may improve their chances of success. Furthermore, the results can help policy‐makers improve the support system for commercialization of eco‐innovations.

Originality/value

As a comparative study of success factors for eco‐innovations and other innovations, the study presents a new way to identify such factors for eco‐innovators.
