Bøger af Jan Boehm

This is the second edition of the established guide to close-range photogrammetry which uses accurate imaging techniques to analyse the three-dimensional shape of a wide range of manufactured and natural objects. After more than 20 years of use, close-range photogrammetry, now for the most part entirely digital, has become an accepted, powerful and readily available technique for engineers, scientists and others who wish to utilise images to make accurate 3D measurements of complex objects. Here they will find the photogrammetric fundamentals, details of system hardware and software, and broad range of real-world applications in order to achieve this. Following the introduction, the book provides fundamental mathematics covering subjects such as image orientation, digital imaging processing and 3D reconstruction methods, as well as a discussion of imaging technology, including targeting and illumination, and its implementation in hardware and software. It concludes with an overview of photogrammetric solutions for typical applications in engineering, manufacturing, medical science, architecture, archaeology and other fields.

Entrepreneurial firms and new venture creation are important drivers for economic growth. Hence, emphasis is put on the question how to adequately stimulate and s- port new business creation. The corresponding discussion has not excluded academic organisations such as universities - quite the contrary. In Germany, this discussion was intensified by changes in the Employee Invention Act (Arbeitnehmererfinder- setz), which now obliges researchers to report an invention to the sponsoring univ- sity, which in return has to decide how the invention it will be exploited. Sub- quently, inventions and patents have emerged as a attractive economic resource for universities. This explains why university administrators have great interest in und- standing how the creative and entrepreneurial orientation of researchers or entire - search teams can be controlled, steered, and enhanced. The discussion we are having in Germany today began in the US more than 20 years ago. With the Bayh-Dole-Act of 1980, a shift in the allocation of property took place similar to the introduction of the Employee Invention Act in Germany today. In ad- tion, the notion of entrepreneurial activities in the context of research organisations has a long-lasting tradition in the US, and the current German system could learn a lot from understanding these developments. This has been the motive for Jan Boehm to look deeper into the field of entrepren- rial orientation in academia, in particular in the US.
