On an "interaction by moments" property of four center integrals

The four center integrals needed in the Hartree Fock approximation and in TDDFT linear response are known to be difficult to calculate for orbitals of the Slater type or of finite range. We show that the interaction of pairs of products that do not mutually intersect may be replaced by the interaction of their moments, of which there are O(N). Only quadruplets of orbitals 'close' to one another need an explicit calculation and the total calculational effort therefore scales as O(N). We provide a new and concise proof of this "interaction by moments" property.Comment: The context of this note is the implementation of TDDFT linear response for extended molecular system

Post-test questionnaire - HRI 1

This questionnaire has been used within the experiments described in a forthcoming publication in order to assess participants' conscious assessment of the quality of the interaction they have experienced with the robot. The questionnaire is based on two established questionnaires assessing participants' perception of `presence': the Temple Presence Inventory (TPI), and the Networked Minds Social Presence Inventory (NMI

Coding Scheme for Negative Utterances

This document contains an abbreviated version of a coding scheme employed for the pragmatic 2-coder analysis of negation types and their felicity. It was used for the coding of negative utterances originating from human-robot dialogues gathered in the experiments described in articles contained in the reference list. Some theoretical parts as well as sections on future work have been removed for space reasons. The complete scheme is contained in the author's thesis. The scheme was devised by the author who also acted as first coder. Additionally a second coder was employed, and those parts of the coding scheme handed to the latter as coding manual are marked as such.Downloa
