Visualisation and the handling of large data sets are key issues in the workflow of many applications in today’s life and engineering sciences. However, from a software and data engineering point of view, these two important services are often located in two separated, i.e. independent and closed software systems. This means that the exchange of data and operations between software systems, i.e...

Object-oriented modelling is considered to be complicated to teach and learn in introductory courses in computer science and software engineering. Animated program visualisation can be significantly used to support teaching objectoriented modelling for beginners. However, there is a lack in instructional methods that support such approach. This paper bridges the gap by introducing a new instruc...

Polysialic acid (PSA), an α2,8-linked homopolymer of N-acetylneuraminic acid (Neu5Ac), is developmentally regulated and its expression is thought to be restricted to a few tissues in adults. Recently, we showed that two human pathogens expressed a derivative of PSA containing de-N-acetyl sialic acid residues (NeuPSA). Here we show that an epitope identified by the anti-NeuPSA monoclonal antibod...

The Wnt signaling pathway regulates multiple aspects of the development of stem cell-like epithelial seam cells in Caenorhabditis elegans, including cell fate specification and symmetric/asymmetric division. In this study, we demonstrate that lit-1, encoding the Nemo-like kinase in the Wnt/beta-catenin asymmetry pathway, plays a role in specifying temporal identities of seam cells. Loss of func...

S-adenosyl-L-methionine (SAM) analogues have previously demonstrated their utility as chemical reporters of methyltransferases. Here we describe the facile, large-scale synthesis of Se-alkyl Se-adenosyl-L-selenomethionine (SeAM) analogues and their precursor, Se-adenosyl-L-selenohomocysteine (SeAH). Comparison of SeAM analogues with their equivalent SAM analogues suggests that sulfonium-to-sele...

A welding head is under development with integrated sensory systems for robotic laser welding applications. Robotic laser welding requires sensory systems that are capable to accurately guide the welding head over a seam in three-dimensional space and provide information about the welding process as well as the quality of the welding result. In this paper the focus is on seam tracking. It is di...

Accurate modelling of individual trees is essential for forestry applications e.g. forestry inventory and biomass estimation. This paper aims to utilise Terrestrial Laser Scanners (TLS) in order to derive a three dimensional (3D) tree structure and compute its volume. A new approach is proposed and tested to estimate the tree structure and leaf area using precise voxel-based tree models. In thi...

Photogrammetry is a well-established method for the use of heritage recording and documentation, whereas terrestrial laserscanning is a rather new technique for 3D object modelling. Both sensor systems have their individual advantages. This paper describes the combined use of both techniques for the modelling of the statue Marc Anton. This statue, located in the city center of Vienna, has an ap...

Modelling and simulation applications for operations in urban areas often set high resolution and fidelity requirements for the 3D environment models. For applications supporting ongoing operations, e.g decision support, mission planning, etc., additional requirements such as time frame and accessibility to the area of interest must also be taken into account in the modelling task. One possible...
