Engineers, irrespective of their disciplines, need effective tools to comprehensively design, model, synthesize and analyze the design a product. This is often closely followed by the need to fabricate a working prototype. Engineers need useful methodologies and tools that can be used in preparation for manufacturing. These tools need to effectively analyze assembly & disassembly since a good assembly design makes a product les expensive to service, repair and maintain. A suite of well-integrated tools assists designers to create, simulate and test in a comprehensive manner. Modern software tools can be used at each stage to create conceptual designs, simulate part geometries, analyze key parameters, and generate motion paths for efficient manufacturing. This paper presents a set of comprehensive procedures and tools that can easily be incorporated into product design and manufacturing from early design through analysis. They consider assembly and disassembly factors up to and including the creation of a working prototype. Due to environmental regulations, designers must think about the product life cycle, recycling and reuse aspects from the very beginning. There is a continuing need for more efficient and rapid design processes which can best be driven by better tools and techniques.

Image processing for enhancement and interpretation is a powerful tool for microscopy and microanalysis. Digital images are arrays of picture elements or pixels each having a coordinate (location) and a value. Two dimensional arrays with single intensity value (monochrome) or triple intensity values (color) pixels are in common use. Software tools and techniques are now available for desk top computers at reasonable cost that allow visualization of higher dimensional arrays and multivalued pixels. The following examples illustrate the application of these tools to microanalysis.Short image sequences (movies) are useful for showing dynamic effects such as the drift of an electron microscope stage with time or the interior of a sample eroded by sputtering on an ion microscope.The values of the pixels of registered images or x-ray maps can be accumulated in a multidimensional histogram (Concentration Histogram Image or CHI). The number of registered maps determines the dimensionality of the histogram.

Purpose – The “academic revolution” that has taken place over the past 50-60 years has brought about many opportunities, but also challenges, in the lives of academics. The “publish or perish” phenomenon can be seen as one manifestation of the heated competition among universities for talent and resources. The resulting increase in publications, the decrease in the time academics have to read them, together with editors’ call for more originality, innovation, and meaning in submitted manuscripts lead to two questions. What techniques can help researchers and PhD students to effectively and efficiently navigate through large bodies of literature? What tools and techniques can be used to enhance the foundations for theorising? The purpose of this paper is to answer these two interrelated questions. Design/methodology/approach – The abstracts of 410 peer-reviewed journal articles connected to ethics in (international) marketing research are explored with software tools. The freely available VOSviewer software is used to visualise the specified body of literature. NVivo is employed to go deeper and explore specific themes identified through VOSviewer. Findings – A total of 17 clusters were identified, representing the major themes in the selected body of literature. Additionally, a number of research avenues and research questions are presented. Research limitations/implications – The analysis is based on the information provided in abstracts. Future research may wish to extend the analysis to full articles. Originality/value – The paper contributes by demonstrating how software tools such as VOSviewer and NVivo can be used to explore large bodies of literature and to experiment with research ideas to enhance the foundations for theorising.
