Comparison of terahertz technologies for detection and identification of explosives
(SPIE, 2014-05) Beigang, R.; Biedron, S. G.; Dyjak, S.; Ellrich, F.; Haakestad, M.W.; Hübsch, D.; Kartaloglu, Tolga; Özbay, Ekmel; Ospald, F.; Palka, N.; Puc, U.; Czerwiñska, E.; Sahin, A. B.; Sešek, A.; Trontelj, J.; Švigelj, A.; Altan, H.; Van Rheenen, A.D.; Walczakowski, M.
We present results on the comparison of different THz technologies for the detection and identification of a variety of explosives from our laboratory tests that were carried out in the framework of NATO SET-193 THz technology for stand-off detection of explosives: from laboratory spectroscopy to detection in the field under the same controlled conditions. Several laser-pumped pulsed broadband THz time-domain spectroscopy (TDS) systems as well as one electronic frequency-modulated continuous wave (FMCW) device recorded THz spectra in transmission and/or reflection. © 2014 SPIE.

Effects of color pairs on warmth perception in interiors
(Society for Imaging Science and Technology, 2016-09) Ulusoy, B.; Olguntürk, N.
Warmth perception is a physical, emotional, semantic, and sensorial bond between people and their environments. Although the effects of single colors have been explored, there has been no research on how paired colors affect warmth perception in interiors. Therefore, the main aim of this study is to investigate these effects of colors and color pairs. Each model was assessed by 32 participants, totaling 96 different participants assessed the color models (Red, White, Green, and their pairs) under controlled conditions, both on a seven-point semantic differential scale and through open-ended questions. The results show that both single colors and paired colors affect warmth perception in interiors. White, Green, and Red are warmer than each other, respectively. Red appears to increase and White appears to decrease the warmth perception of their pairs in interiors. Another important finding of the study is that there is no effect of color location in paired colors. © Society for Imaging Science and Technology 2016.

Understanding responses to materials and colors in interiors
(Wiley, 2017) Ulusoy, B.; Olguntürk, N.
This article investigates the free associations of materials and colors in the context of interior architecture. Materials and colors rarely appear alone in interiors; therefore, in the scope of this study, the researchers explored material pairs and color pairs in addition to single materials and single colors. To elicit free associations from these interior design elements, 192 randomly selected volunteers participated in an experiment using a group of material (fabric, timber, plasterboard) and color (red, green, white) models under controlled conditions. The results contribute to an increased understanding of the associations between the concepts of materials and colors in interiors. While, each model was associated with sensory descriptors, only some models were associated with symbolic or affective descriptors. Single materials were related to different descriptors in interiors on their own, but when they were paired they were associated with fewer affective descriptors. The results showed that color pairs were always associated with all types of descriptors with an exception of red and green color pair, which was not mentioned with affective descriptors. The study findings are expected to be beneficial for interior architects, architects, product designers and researchers who want to shape and investigate a user's experience of interiors. © 2016 Wiley Periodicals, Inc.
