Behavior adaptation based on execution experience can be a practical tool to increase the robustness of a robot behavior learned from demonstration. While demonstration learning is a powerful technique for the development of robot behaviors, in general development remains a challenge. This work presents an approach for policy improvement through a tactile interface located on the body of the ro...

An experiment was developed using aeration of water for demonstrating the phenomenon of mass transfer. The demonstration was designed to provide both conceptual and practical insight of the mass transfer process. A bubble column fitted with a sieve tray was used to carry out the experiment. The air flow rate and hole size of the sieve tray were varied. Mass transfer coefficient was obtained fro...

The work of science teachers can be viewed from a variety of perspectives. In this article, teaching is seen as an activity in which teachers deliberate in the practical domain to decide on actions and goals. In the first part of the article, it is argued that, because practical reasoning is similar to scientific reasoning, a model of practical conceptual change can be developed that is analogo...

BACKGROUND Prescribing inhalers without imparting adequate education regarding proper technique of their usage may result in suboptimal clinical improvement and wastage of medication. Training interventions using a standard check-list may help improve faulty techniques and enhance drug efficacy. METHODS Patients using metered dose inhaler (MDI) were included in the study. Inhaler technique wa...

To facilitate the creation and usage of custom SMT systems we have created a cloud-based platform for do-it-yourself MT. The platform is developed in the EU collaboration project LetsMT!. This system demonstration paper presents the motivation in developing the LetsMT! platform, its main features, architecture, and an evaluation in a practical use case.

The paper presents results from the first SUITED (multi-segment System for broadband Ubiquitous access to InTErnet services and Demonstrator) demonstration campaign, focusing on the GMBS (Global Mobile Broadband System) terminal. A practical user mobility solution for a heterogeneous access network and a trial realisation is described. A new vehicular satellite active antenna concept, developed...

This paper presents a novel method to use the current transformers with a comparator and communication systems to serve against the pilferage of electricity from the overhead transmission lines. The block diagram representation has been used for the lucid demonstration of the complete process. Also, a practical example has been discussed to substantiate and validate the research.

We report an experimental demonstration of optimal storage and retrieval of heralded single-photon wave packets using electromagnetically induced transparency (EIT) in cold atoms at a high optical depth. We obtain an optimal storage efficiency of (49 ± 3)% for single-photon waveforms with a temporal likeness of 96%. Our result brings the EIT quantum light-matter interface closer to practical qu...

Autoradiographic demonstration of 3H-hypoxanthine incorporation in small numbers of amniotic fluid cells cultured on coverslips is a rapid and practical technique in the prenatal diagnosis of the Lesch-Nyhan mutation. An affected male fetus, a normal male fetus, and a heterozygous female fetus were identified within 14 days after amniocentesis in three pregancies at risk for the Lesch-Nyhan syn...
