Purpose – The purpose of this paper is to empirically examine organizational cross-culture differences in public-private research-oriented relationships. More precisely, it focusses on the analysis university-industry collaborations partnering for research agreements with the aim of fostering the transfer of knowledge and innovation. It analyzes the key organizational cross-cultural differences that could hinder the successful performance of these agreements from a relationship marketing (RM) perspective. Design/methodology/approach – Based on a comprehensive literature review of organizational culture and RM, a quantitative study was carried out and a structural equation model was proposed and tested. Findings – Cross-cultural organizational differences in private-public sectors are proved to negatively influence relationship performance. Market orientation difference appears as the most significant barrier to relationship performance, followed by time orientation difference and to a lesser extent flexibility difference. Originality/value – By integrating organizational culture and RM literatures, the main contribution of this paper is the cross-cultural analysis of private-public relationships (in this case university-industry relationships) from the perspective of RM. Hence, this research will inform management seeking to develop successful public-private collaborations by enhancing their understanding of cross-cultural factors underlying relationship success and failure.

Convergent Beam

The history of the Convergent Beam Electron Diffraction (CBED) is shortly introduced. Symmetry determinations[1] of crystals or the point groups and space groups of 3, 4, 5 and 6 dimensional crystals, and crystal structure analysis including the determination of charge density distribution and potential distribution of a crystal are briefly reviewed.[2] Then, the large angle CBED (LACBED) technique is described.[3] Applications of the LACBED technique to the determinations of the Burgers vector of a dislocation, the shift vector at a stacking fault, the precise orientation difference of a twin domain and the strain of an advanced multi-layer material are reviewed.

Apparent Orientation

Helmholtz first reported that when the horizontal meridians of the two eyes are aligned, the vertical meridians of the two eyes are tilted outwards (with respect to each other) by approximately 2°. We adapted Nakayama's technique (1977 Proceedings of the Society of Photo-Optical Instrument Engineers120 2 – 9) using the minimal apparent motion of alternating dichoptic images to measure the relative tilt of corresponding vertical and horizontal meridians located up to 20 deg away from the fovea. Observers were presented with the alternating dichoptic images of a pair of dots or a pair of extended lines which had a relative tilt (binocular orientation difference) of between −5° and +5°. The images were alternated at a rate of 0.2 Hz. Observers were asked to select the pair of images which produced the smallest amount of apparent orientation change. The vergence angle of the binocularly visible fixation point was varied between 28 cm and infinity. On the assumption that minimal apparent motion is a valid indicator of binocular correspondence, the corresponding vertical meridians of the two eyes remained offset by around 2 deg even when they were located 20 deg eccentrically. The corresponding horizontal meridians remained approximately aligned even when they were elevated by up to 20 deg. Corresponding horizontal meridians were altered when the vergence angle was changed but corresponding vertical meridians were unaffected for most individuals. With the eyes held in an elevated position, both vertical and horizontal meridians were altered by a similar amount when the vergence angle was altered, indicating a change in cyclovergence.

This paper examines the fidelity of a commodity range camera for assembly inspection in use cases such as augmented reality-based assembly assistance. The objective of inspection is to determine whether a part is present and correctly aligned. In our scenario, shortly after the mechanics assembled the part, which is denoted as on-the-fly inspection. Our approach is based on object tracking and a subsequent discrepancy analysis. Object tracking determines the presence, position, and orientation of parts. The discrepancy analysis facilitates to determine whether the parts are correctly aligned. In comparison to a naive position and orientation difference approach, the discrepancy analysis incorporates the dimensions of parts, which increases the alignment fidelity. To assess this, an experiment was conducted in order to determine the accuracy range. The results indicate a sufficient accuracy for larger parts a noticeable improvement in comparison to the naive approach.

Moiré Patterns

Moiré patterns in depth are reported when spatially periodic stimuli are viewed stereoscopically. Near-vertical square-wave gratings with horizontal disparity effected by orientation difference produce a ‘venetian blind’ effect. A single grating is observed divided into horizontal layers, the number of layers being a direct function of orientation difference. Lines within each layer are slanted with respect to the frontoparallel plane, becoming more so with increasing orientation difference. Subjects with stereo deficits report a decreased effect. Quantitative reports implicate stereoscopic mechanisms responsible for this unique, internal preservation of moiré patterns.
