Abstract

Purpose

In recent years, continuous expansion of the scale of the new energy export industry in China caused a boycott of American and European countries. Export injury early warning research is an urgent task to develop the new energy industry in China. The purpose of this paper is to build an indicator system of exports injury early warning of the new energy industry in China and corresponding quantitative early warning models.

Design/methodology/approach

In consideration of the actual condition of the new energy industry in China, this paper establishes an indicator system according to four aspects: export price, export quantity, impact on domestic industry and impact on macro economy. Based on the actual data of new energy industry and its five sub-industries (solar, wind, nuclear power, smart grid and biomass) in China from 2003 to 2013, GM (1,1) model is used to predict early warning index values for 2014-2018. Then, the principal component analysis (PCA) is used to obtain the comprehensive early warning index values for 2003-2018. The 3-sigma principle is used to divide the early warning intervals according to the comprehensive early warning index values for 2003-2018 and their standard deviation. Finally, this paper determines alarm degrees for 2003-2018.

Findings

Overall export condition of the new energy industry in China is a process from cold to normal in 2003-2013, and the forecast result shows that it will be normal from 2014 to 2018. The export condition of the solar energy industry experienced a warming process, tended to be normal, and the forecast result shows that it will also be normal in 2014-2018. The biomass and other new energy industries and nuclear power industry show a similar development process. Export condition of the wind energy industry is relatively unstable, and it will be partially hot in 2014-2018, according to the forecast result. As for the smart grid industry, the overall export condition of it is normal, but it is also unstable, in few years it will be partially hot or partially cold. The forecast result shows that in 2014-2018, it will maintain the normal state. In general, there is a rapid progress in the export competitiveness of the new energy industry in China in the recent decade.

Practical implications

Export injury early warning research of the new energy industry can help new energy companies to take appropriate measures to reduce trade losses in advance. It can also help the relevant government departments to adjust industrial policies and optimize the new energy industry structure.

Originality/value

This paper constructs an index system that can measure the alarm degrees of the new energy industry. By combining the GM (1,1) model and the PCA method, the problem of warning condition detection under small sample data sets is solved.

Abstract

Purpose

The purpose of this paper is to describe a novel, nanomaterial‐based X‐ray imaging technology, developed at the University of North Carolina.

Design/methodology/approach

The paper describes a unique X‐ray source, based on field emission from a carbon nanotube (CNT) cold cathode and discusses its application to computer tomography (CT).

Findings

CNT‐based X‐ray sources are shown to offer improved performance over conventional thermionic devices and allow the design of gantry‐free, stationary CT systems with faster scanning speeds and better image quality. The field emission technology has been commercialised by Xintek and a joint venture with Siemens, XinRay Systems, aims to commercialise CT imagers based on the technology.

Originality/value

The paper describes a novel approach to the generation of X‐rays and its use in medical CT imaging systems.

Abstract

Purpose

Define, measure, analyze, improve and control (DMAIC) and define, measure, analyze, design and verify (DMADV) are two Six Sigma methodologies that improve quality in a process or product. In general, if the product design improvement in reliability cannot satisfy the failure‐free performance of Six Sigma, the DMADV process is used to create or redesign new product designs. However, the original function may be affected, and the product development cycle time may be enhanced due to a redesigned process. This paper aims to propose a new procedure to combine the reliability parameter and critical to quality (CTQ) to improve a product's reliability and to reduce the number of engineering changes without redesigning.

Design/methodology/approach

The study influences the failure parameter to find out the mean time to failure (MTTF) tree and utilizes the DMAIC process for improvement. It is important to maintain the function while improving time. This study looks at a cold cathode fluorescent lamp (CCFL) case.

Findings

The CCFL case uses the DMAIC process finds that important root cause improvement can increase MTTF twofold.

Originality/value

The paper provides useful information on product reliability improvement using the DMAIC process.

Abstract

Production for Plenty. At a time when many established industrial exhibitions are struggling to survive, it is a bold step on the part of the Institution of Production Engineers to launch the first Production Exhibition and Conference which they hope will become an annual event. This will be an exhibition with an entirely new theme—one which the general public, as well as industry, are coming to know and appreciate as a force for the future in both their working and domestic lives.

Abstract

ON Friday, March 24, 1961, the Minister of Aviation, Mr Peter Thorneyeroft, officially opened a new high supersonic speed wind tunnel at the Royal Aircraft Establishment, Bedford. This tunnel provides the final stage in the present plans for expansion of the wind tunnel facilities at Bedford, being capable of providing speeds from Mach 2.5 up to Mach 5 in a working section measuring 4x3 ft. Three other tunnels arc already in operation at Bedford—these being the 13x9 ft. working section low‐speed tunnel, the 3x3 ft. tunnel, which is transonic and supersonic to Mach 2, and the 8x8 ft. tunnel, which is subsonic and supersonic to Mach 2.8.

Abstract

THE Twenty‐fifth S.B.A.C. Flying Display and Exhibition is to be held at Farnborough during the week Monday, September 5, to Sunday, September 11, promises to be one of the most interesting yet held as for the first time member companies of the Society have nominated for entry aircraft from member countries of the European A.I.C.M.A. (Association Internationale des Contructeurs de Materiel Aérospatial) that are powered by British engines. Seven European aircraft will be taking part, four of them sponsored by Bristol Siddeley Engines Ltd. and three by Rolls‐Royce Ltd. The dominant theme of the Show will be collaboration, and it is fitting that the foreign aircraft have been sponsored by the aero engine manufacturers as they have advanced farther along this road than the airframe companies. Between them, they have close associations with practically all the major engine manufacturers in the Western world. Apart from the models and displays which will be mounted by the major airframe and engine manufacturers reflecting their growing involvement with European projects, the stands of the Associate Members of the Society of British Aerospace Companies will have many examples of materials, techniques and equipment that these companies are producing in support of current programmes, some of which will be for the American military aircraft now on order for the Royal Air Force and the Royal Navy.

Abstract

Purpose

A novel sensor system is described that can replace the need to use a touch screen, mouse or keyboard for use with either a thin film transistor (TFT) or cathode ray tube (CRT) screen.

Design/methodology/approach

A tri‐colour photodiode in a colour sensor pen (CSP) is used as an input to depict where a user is pointing by detecting a dynamic kaleidoscope of colours flashed onto the screen. The most easily detected colours are placed around the predicted position of the sensor. The output from the sensor is filtered and transmitted to a computer where colour is translated into a corresponding co‐ordinate. An artificial neural network (ANN) ensures that optimum colours are placed closest to the sensor by predicting future pointer position.

Findings

The CSP successfully provided an input that depicted where a user was pointing. Sensors tested were not able to differentiate more than 28 colours on a TFT screen but an ANN system made them more accurate. Hue and Saturation were successfully used to model colour in a two‐dimensional colour grid as they were unaffected by brightness. The sensor output was successfully converted into a co‐ordinate and used to move a cursor. The kaleidoscope of colours was dynamic as it changed size and colour to increase accuracy. The ANN successfully predicted future positions to assist the sensor in making optimum colour detections. The best predictions of future positions were obtained with four and eight hidden neurons and there did not appear to be any significant advantage in training with more than 2,000 epochs. The system has performed satisfactorily for various inputs.

Research limitations/implications

The novel light pen works on TFT and CRT screens. Problems included the time that colours needed to be left on a screen to be detected and the limited number of colours that could reliably be detected. These were overcome by using a dynamic kaleidoscope of colours to improve colour detection and an ANN to predict future pointer positions, based on previous locations. This prediction was used to place optimum colours closest to the sensor in order to increase accuracy. Further testing is taking place to confirm that the sensor can be used at any angle.

Practical implications

The novel light pen type peripheral and intelligent colour sensing system can replace the need to use a touch screen, mouse or keyboard.

Originality/value

The new intelligent colour sensing system works on either a TFT or CRT screen. The use of the colour translation and sensor and the ANN to predict future pointer position are all novel.
