Gyroscopes are fascinating instruments with a history of about 200 years. When J.G.F. Bohnenberger presented his machine to his students in 1810 at the University of Tuebingen, Germany, nobody could have foreseen that this fascinating development would be used for complex orientation and positioning. At the University of Stuttgart, Germany, a collection of 160 exhibits is available and in transition for a sustainable future. Here, the systems are digitized in 2D, 2.5D and 3D and are made available for a world-wide community using OpenAccess platforms. The technologies being used are Computed Tomography, Computer Vision, Endoscopy and Photogrammetry. The workflows for combining voxel representations and colored point clouds are described, to create Digital Twins of the tangible assets. Advantages and disadvantages are discussed und work for near future is outlined in this new and challenging field of Tech Heritage digitization.

The preservation of cultural heritage assets of all kind is an important task for modern civilizations. This also includes tools and instruments that have been used in the previous decades and centuries. Along with the industrial revolution 200 years ago, mechanical and electrical technologies emerged, together with optical instruments. In the meantime, it is not only museums who showcase these developments, but also companies, universities, and private institutions. Gyroscopes are fascinating instruments with a history dating back 200 years. When J.G.F. Bohnenberger presented his machine to his students in 1810 at the University of Tuebingen, Germany, nobody could have foreseen that this fascinating development would be used for complex orientation and positioning. At the University of Stuttgart, Germany, a collection of 160 exhibits is available and in transition towards their sustainable future. Here, the systems are digitized in 2D, 2.5D, and 3D and are made available for a worldwide community using open access platforms. The technologies being used are computed tomography, computer vision, endoscopy, and photogrammetry. We present a novel workflow for combining voxel representations and colored point clouds, to create digital twins of the physical objects with 0.1 mm precision. This has not yet been investigated and is therefore pioneering work. Advantages and disadvantages are discussed and suggested work for the near future is outlined in this new and challenging field of tech heritage digitization.

Abstract. The city walls of Florence constitute a complex system: six circles and at least nine distinct phases of use and transformation, from the foundation of Florentia to Florence Capital, to contemporary adjustments. The DIDA, Department of Architecture of the University of Florence with the Municipality of Florence, has been carrying out since 2012 the FIMU project with the study of the various walls circuits and diachronic surveys of the surviving wall sections. The aim is to combine and harmonize the historical data with technical-scientific innovation, expressing its own vision of the relationship between the history of the city of Florence and the correct valorization of one of its important Landmark. Every citizen must be able to recognize in the traces of the past his belonging to a community, the results expected from this research are the realization of an informative-didactic and informative apparatus that will emphasize this important historical testimony of Florence and its transformations occurred over the centuries. Data acquisition, processing and visualization methods define this research as ‘experimental’ for the knowledge and evolution of a historic city that would contribute to elevating services for the technical scientific community and the citizen, to which data would become available currently ‘raw’ with the preparation of an apparatus based on a database through the ‘Open Data’ platform of the Municipality of Florence.

Generally a digital twin is a software-model as a prototype for some product, ordered by a customer. It shell be used on all stages of industrial production of this ordered product, compering the actual state with the model und correcting the differences. A “virtual world” will be created from the “real word” and both “worlds” communicate with each other during production. At the educational institutions of engineering like universities, trainings centres or schools the digital twins are software-models of industrial plants, which are simulated and visualized similar to its industrial originals and synchronized with them. The presented paper shows steps of design of digital twins upon some examples of the master degree program at the University of Applied Sciences Darmstadt. It will be described why and how it is possible to use the digital twins. The ways from an original device to its model will be drawn. The different stages of the development of software-models, which are equipped with different levels of source code, will be shown. The actual trends to include the hardware into a software-model, so called hardware-in-the-loop and rapid control prototyping, will be described. Finally the advantages and disadvantages of digital twins for engineering study including the economic considerations will be discussed.

This paper presents the practical issues involved in introducing e-leaming for the Faculty of Mathematics and Physics (FMF) at the University of Ljubljana, Slovenia. It begins with a short history of e-learning at FMF and is followed by a discussion about the choice of the open source software (Moodle, svn, wiki platform) as the foundation for the web based learning; its advantages and disadvantages. The focus is on materials that enhance classroom learning, conform to learning standards, and at the same time address the needs of the end users - the students. In the end, the results of a survey about the students' attitudes towards e-learning are presented; in general and specific to the e-learning environment at FMF.

This paper gives a case history of a transfer of technology from the university sector to the private sector. The particular example chosen is a speech transcription system. This is a specific example of the problems of trying to commercialize a product which has been developed in the university sector, but there are a number of more generally applicable lessons which can be learned from the case study. The paper illustrates some of the pitfalls which can occur and underlines how the constraints of academic life and those in the commercial sector have both advantages and disadvantages in this difficult exercise.

Twenty nine items of correspondence from the mid-1950s discovered recently in the archives of the University Marine Biological Station Millport, and others made available by one of the illustrators and a referee, shed unique light on the publishing history of Collins pocket guide to the sea shore. This handbook, generally regarded as a classic of its genre, marked a huge step forwards in 1958; providing generations of students with an authoritative, concise, affordable, well illustrated text with which to identify common organisms found between the tidemarks from around the coasts of the British Isles. The crucial role played by a select band of illustrators in making this publication the success it eventually became, is highlighted herein. The difficulties of accomplishing this production within commercial strictures, and generally as a sideline to the main employment of the participants, are revealed. Such stresses were not helped by changing demands on the illustrators made by the authors and by the publishers.
