Tsigai and Improved Valachian are the most spread sheep breeds in Slovakia. Both are multi-purpose breeds (Krupová et al., 2009), well adapted to local climate and environment. Tsigai is one of the oldest native breeds in areas from 500 to 800 m above sea level, mostly in the semi-extensive production system (Krupová et al., 2009), while improved Valachian is mostly kept in mountains and foothi...

$EVWUDFW The existence of mechanisms to describe and evaluate assertions in programming languages helps to reduce the conceptual gap existing between the specification and implementation phases in the software development, improving both tasks. Java, originally used as an Internet-oriented implementation language, is becoming a general-purpose language, which unfortunately does not provide this...

Pointing tasks are a crucial part of today’s graphical user interfaces. They are well understood for flat displays and most prominently are modeled through Fitts’ Law. For novel displays (e.g., curved displays with multi-purpose areas), however, it remains unclear whether such models for predicting user performance still hold – in particular when pointing is performed across differently oriente...

Dr.-Ing. Jutta Fortmann Wrist-Worn Light-Based Smart Digital Jewellery In recent years wearable devices have become an emerging trend in the consumer market. However, recent studies in the U.S. show that a third of owners of a wearable device abandon its use within six months. Supposed reasons are, among others, a lack in useful functions, aesthetics, and comfort. Smart Digital Jewellery has be...

Last generation multi-purpose printers or MFPs are very capable computational devices, often equipped with a built-in programming framework which eases its extensibility. However, they include so much functionality that often it is too hard to operate them. This paper describes two services which turn MFPs into Ubiquitous Computing devices, i.e. more intuitive, personalised, user-friendly, upgr...

Effective usage of a general purpose modeling language in software engineering poses a need for language customization – adaptation of the language for a specific purpose. In the context of the Unified Modeling Language (UML) the customization could be done using two mechanisms: developing profiles and extending the metamodel of UML. This paper presents an industrial case study on the choice be...

This paper addresses production systems optimisation in uncertain context. A standard framework for solving such type of problem is depicted in a 3-step approach. The two first steps consist of off-line characterisation of the problem and calculation of solutions with some desired performance. A generic approach to implement these off-line steps is introduced in this paper. This approach relies...

When Alan Turing laid the foundation for computation in 1936, he wanted to show what computation can do, and what it cannot do. For the latter, he invented a problem that we now call the “Halting Problem”. In modern terms, it is as follows. In a general-purpose programming language, write a program that reads a text (character string) p representing a program in that same language, and reads an...
