In this paper D is a non empty set. We now state several propositions: (1) Let D be a non empty set, and let S be a non empty subset of D, and let f be a binary operation on D, and let g be a binary operation on S. Suppose g = f [:S, S :]. Then (i) if f is commutative, then g is commutative, (ii) if f is idempotent, then g is idempotent, and (iii) if f is associative, then g is associative. (2)...

The paper presents the results of the project which examines the level of accuracy that can be achieved in precision indoor positioning by using a pedestrian dead reckoning (PDR) method. This project is focused on estimating the position using step detection technique based on foot-mounted IMU. The approach is sensor-fusion by using accelerometers, gyroscopes and magnetometers after initial ali...

A novel Inductive Contactless Energy Transfer (ICET) system is presented in this paper. The energy is transferred using a rotatable air gap transformer and a power electronic converter. To minimize total losses of the system a series resonant circuit is applied, assuring zero current switching condition for IGBT power transistors. The analytical expression of the transfer dc voltage gain is giv...

Model-driven software engineering is a well investigated and heavily used technique for software development. Within automation engineering we want to benefit from these ideas and concepts by adopting them to systems engineering. Parallel processes in systems engineering demand high synchronization effort between different disciplines, their engineers, and processes. Unfortunately, these proces...

In this paper a greedy algorithm for some variants of the sequencing by hybridization method is presented. In the standard version of the method information about repetitions is not available. In the paper it is assumed that a partial information of this type is a part of the problem instance. Here two simple but realistic models of this information are taken into consideration. The first one a...
