Trust is a factor that becoming more prominent in human robot interaction research. Only few approaches so far tackle the challenge of data-driven trust assessment. In this paper, we present data set consisting motion tracking from an industrial collaboration task. The collected during manipulation experiment has been designed to elicit different levels participants. Additionally, participants filled out standard questionnaire. allows for developing and testing assessment algorithms.

Human-robot collaboration in industrial settings is an expanding research field robotics. When working together, robot mistakes are important factor to decrease trust and therefore interferes with cooperation. It unclear whether explanations help restore human-robot after a mistake. In our study, we investigate system as trust-repairing action makes mistake collaborative task helpful. Our pilot study revealed that users more interested solutions errors than they just why the error happened....

An implementation of triples corrections for the calculation electronic ground states and singlet triplet excitation energies within CC3 model is discussed. At most objects size V2O2 V3O are kept in memory on disc, respectively (V number virtual orbital O occupied orbitals). The used strategy means that more terms scales as V4O3 has to be calculated than if amplitudes disc but it allows larger cases handled. Sample calculations presented benzene.
