This article offers a novel approach for managers to increase creativity in their teams by measuring individual personality characteristics crucial for creative people. We assess inter-personal interaction with sensor-equipped badges worn on the body. In a research project with 22 study subjects, who wore the badges during work for one month, we were able to predict extroversion, neuroticism, o...

This paper presents a mirror symmetrical dielectric totally internally reflecting concentrator (MSDTIRC). Here, its electrical and optical performances are investigated for building integrated photovoltaic applications. This concentrator is designed to tackle two issues: (i) providing sufficient gain in order to increase the electrical output of a solar photovoltaic (PV) system and (ii) reducin...

This pioneering study describes preliminary research on how combined analysis of social and psychological self might increase organizational creativity. By measuring inter-human interaction with sensor-equipped tags worn on the body we studied social interaction in a much closer, “microscopic” way than ever before. In a research project with 22 study subjects, who wore the badges during work fo...

Long mirrors coated with thin films are used for a wide range of applications, e.g., focusing or collimating high-energy optics. Focusing incident x-ray radiation is one the major applications astronomical telescopes, and collimation divergent sources experimental setups to confine expand radiation. Both utilize grazing angle reflection, which typically enhanced using reflective films. One chal...

Extremely large telescopes (ELTs) are the next generation of ground-based reflecting telescopes of optical wavelengths. ELTs possess an aperture of more than 20 meters and share a number of common features, particularly the use of a segmented primary mirror and adaptive optics systems. In 2005, the European Southern Observatory introduced a new giant telescope concept, named the European Extrem...

A fundamental discovery in segmented-mirror active optics is described: symmetrizing the geometry of the sensor–actuator array provides a computationally effective symmetrization of the mathematical description for the figure control of a Keck-type telescope mirror. The author establishes a universal mathematical control model and provides an efficient algorithm to solve this model equation set...

The first test of nanoscale-focusing Kirkpatrick-Baez (KB) mirrors in the nested (or Montel) configuration used at a hard X-ray synchrotron beamline is reported. The two mirrors are both 40 mm long and coated with Pt to produce a focal length of 60 mm at 3 mrad incident angle, and collect up to a 120 µm by 120 µm incident X-ray beam with maximum angular acceptance of 2 mrad and a broad bandwidt...

Data are presented from a novel microfocus X-ray generator installed with a choice of ellipsoidal specularly reflecting mirrors. Diffraction data from proteins show the useful flux from this low-power device to be approaching equivalence with that from many far more powerful generators. Intensity measurements show that for small crystals the brilliance is now restricted by the performance of th...

Aspheric optical components are the indispensable part of modern optics systems. With the constant development of aspheric optical fabrication technique, the systems with large aperture convex aspheric optical components are widely used in astronomy and space optics. Thus, the measurement of the figure error of the whole convex aspherical surface with high precision comes to be a challenge in t...

The effect of energetic Xenon ion bombardment on the extreme ultraviolet (EUV) reflectivity performance of mirrors is of vital importance for the performance of dischargeand laserproduced plasma extreme ultraviolet lithography (EUVL) sources. To study these effects, we measured absolute and relative reflectivities at the National Institute of Standards and Technology and the Interaction of Mate...
