Recent studies concerning future air transport systems propose an operational model based on contract-based air transportation system concepts, which impose 4D (spatial and time) constraints, called target windows (TWs), at different parts of the flight plan that an aircraft has to respect. The paper's aim is to find the set of all possible approaches for controlling punctuality at destination without violating the constraints imposed by a given sequence of TWs.

This paper investigates the electrical conductivity and corrosion protection properties of a conductive coating composed of epoxy resin and carbon black in a sodium chloride (NaCl) solution. The results shown in this paper provide an insight into conductive paint and corrosion protection for future industrial applications and development.

Musculoskeletal conditions are a major health concern in the USA because of a large, ageing population and increased occurrence of sport-related injuries. Bone tissue engineering may offer a less painful alternative to traditional bone grafts with lower risk of infection. The purpose of this paper is to present a novel porogen-based fabrication system for tissue engineering scaffolds using sucrose as the porogen building material.

Surface defects reduce fatigue strength and may greatly reduce component reliability, particularly in pressure vessel weld regions, springs, and other applications. The fatigue strength of components, and thus their reliability, can be substantially increased by tensile overloading prior to use. This paper investigates the effect of tensile overload on small cracks by applying a tensile overload to steel plates containing semicircular slits that simulate small surface cracks and by determining the degree of increase in the fatigue strength.

This paper aims to find the optimal values of the reaction rates coefficients for the combustion of a methane/air mixture for a given reduced reaction mechanism which has a high appropriateness with full reaction mechanism. The results demonstrate that the genetic algorithm (GA) inversion process promises the ability to assess combustion behaviour for methane, where the reaction rate coefficients are not known. Moreover it is shown that GA can consider a confident method to be applied, straightforwardly, to the combustion chambers, in which complex reactions are occurred.

The benefits of lean enterprise management are well-documented. More and more companies have embraced lean as the only way to manage their business. While the principles of waste reduction, human optimization, distributed design, and supply chain management has served many companies very well, these benefits may alternatively lead to absolute failure. The current downward shift in the marketplace poses important challenges to the lean paradigm. Can companies apply lean in a shrinking economy, while focusing on innovations needed for survival?

Ready-to-wear garments are manufactured using predefined size charts which allow for the reduction of production cost. It is, therefore, practically impossible to obtain a perfect fit between a piece of cloth and an individual buyer. However, the relation between size charts and body dimensions is not constant because of changes that occur in the human population. Recent body surveys in Germany proved that a garment sizing system for a certain body type does not cover more than the 25 per cent of the population in which it is addressed. Consequently, for a successful garment mass customization model, the development and maintenance of up-to-date anthropometric databases of the target market population is essential. This paper therefore derives a new method for developing sizing systems for the mass customization of garments.

This review of the 2009 International Robot Exhibition in Tokyo, Japan, is based on in-depth interviews with exhibitors, and the reporter's personal insight into the Japanese robot industry. A dramatic change is observed in the direction of Japanese industrial robotics as the industry attempts to overcome the worldwide economic crisis. Consequently, the author predicts that new markets, new applications, new robot types, and new robot-based production systems will be emerging.

Fatigue negatively affects physical and mental processes representing a major threat to flight safety. This paper presents the development of a pilot fatigue detection scheme using fuzzy logic which can be used as a starting-point for future research in the development of: safety monitoring systems for warning and/or triggering of automatic control compensation; pilot fault-tolerant control laws; human-pilot models for simulation; handling qualities assessment and control laws design. The approach for detection proposed in this paper is a viable alternative to existing methods based on physiological measurements such as electrical activity of the brain, pulse, body temperature, etc. which imply direct and permanent connection of the pilot to the measurement system and interfere adversely with pilot comfort and his/her ability to perform the task.

For several years, the domestic markets of manufacturing organizations have started to reach maturity and companies have sought to expand their international operations in order to grow. This has meant that there has been an increasing emphasis on the debate on whether companies should remain global or localize their marketing mix, and to what extent each element should be adapted or standardized. This article, which is an updated and revised version of an award-winning paper previously presented at the Flexible Automation and Intelligent Manufacturing Conference in 2009, explores the degree to which manufacturing organizations need to standardize or adapt elements of their marketing mix and demonstrates how a balance can be created between global and local approaches.
