The article focuses on the collection of papers presented at the Second International Conference on Microchannels and Minichannels, held in Rochester, New York, June 17-19, 2004. The conference was hosted under the joint sponsorship of the American Society of Mechanical Engineers and Rochester Institute of Technology. The first paper by highlights the research needs and application of advanced instrumentation, such as differential pressure measurements, current distribution and neutron radiography, in studying the water distribution in minichannel passages in PEM fuel cells.

British mechanical engineer Jack Keiser's postwar career in industrial education was simultaneously a career in justice work and Christian industrial mission. This paper examines the Christian critique of industry Keiser developed early in his career, as he transitioned in 1949–1950 into his life's work in firm-based industrial education, and asks how historians of technology might interpret a critique that characterized industry in hyperbolic terms as enslaving or demonic. Keiser's was part of an international critique connected to three important post-war Christian institutions: Student Christian Movement, the Industrial Mission Movement, and the World Council of Churches. He engaged with justice at both an intimate and a cosmic level, intimately through face-to-face relationships with apprentices and trainees under his supervision, and cosmically by engaging with the biblical prophets through whom God called for justice.

This paper offers a multi-perspective view on engineering education at RWTH Aachen University: curriculum design, examples of newly developed teaching methods for engineering curri-cula, and teaching competencies and teacher qualification. It is based on the theories of student-centred learning, project learning, social skills, etc., but the paper covers the practical implications and ways of implementation of these items in a current design process of a new study programme: In the course of the Bologna process the mechanical engineering study programme of RWTH Aachen University has encountered a complete and thorough revision responding to the need of present-day technical students and - accordingly - to the fast-growing requirements of the engineering industry. This change process will be presented. A case study from engineering informatics shows concepts for modern teaching methods, responding to the requirements of students and industry, especially regarding social skills. Teaching competencies have to change and grow accordingly. Thus, a concept for the improvement of educational skills and abilities of engineering teachers - integrated into their work process - is demonstrated. [ABSTRACT FROM AUTHOR]

This paper takes an empirical look into industrial design in process and metal industries. The data are based on a case study of an industrial design pilot project at a company that is a market leader in mineral processing systems. In the paper, the overall structure of the project is outlined and aspects of design work are addressed through detailed analysis of interactions between the participants. In addition, the role of visualizations and the nature of design problems are examined. The conclusions of the paper include implications for the organization of industrial design projects. In addition, general notes are made about the nature of industrial design within the company—and technology intensive areas in general. [ABSTRACT FROM AUTHOR]

In this paper, we present all necessary generalisations to extend the bridging scale, a finite-temperature multiple scale method which couples molecular dynamics (MD) and finite element (FE) simulations, to two dimensions. The crucial development is a numerical treatment of the boundary condition acting upon the reduced atomistic system, as such boundary conditions are analytically intractable beyond simple one-dimension systems. The approach presented in this paper offers distinct advantages compared to previous works, specifically the compact size of the resulting time history kernel, and the fact that the time history kernel can be calculated using an automated numerical procedure for arbitrary multi-dimensional lattice structures and interatomic potentials. We demonstrate the truly two-way nature of the coupled FE and reduced MD equations of motion via two example problems, wave propagation and dynamic crack propagation. Finally, we compare both problems to benchmark full MD simulations to validate the accuracy and efficiency of the proposed method. [ABSTRACT FROM AUTHOR]

Lot streaming is the process of splitting a job or lot to allow overlapping between successive operations in a multistage production system. This use of transfer lots usually results in a substantially shorter makespan for the corresponding schedule. In this paper, we study the discrete lot streaming problem for a single job in no-wait flow shops. We present a new linear programming formulation for the problem. We show that the optimal solutions are the same for the m x 2 case with or without no-wait constraints. We also present a fast, polynomial-time solution method for this case. For the general case, we prove that any solution which is 'close' to the continuous optimal solution will be a good approximation for the discrete problem. This property allows us to present two quickly obtainable approximations of very good quality. [ABSTRACT FROM AUTHOR]
