Mobile devices transformed the way students access shared knowledge today. The initiative described through the usage of mobile technologies for learning purposes is called mobile learning or m-learning. It is a promising platform because it is learner-centred, enhances collaboration and flexibility of the learning process and enables students with physical disabilities to reach educational mat...

In this paper, we describe a framework for the analysis of technology-induced errors, extending approaches from the emerging area of usability engineering. The approach involves collection of a rich set of data consisting of audio and video recordings of interactions of healthcare workers with health information systems under simulated conditions. The application of the approach is discussed, a...

According to the modern conceptions the cholesteric liquid crystals (CLCs) can be considered as one dimensional 1D) photonic crystals. The existence of the selective reflection band and the ability to change the selective reflection avelength over a wide range under the action of applied external forces make it possible to use the CLCs in the data ecording, processing and storage systems. Prese...
