A new approach to diffraction modelling for line-of-sight (LOS) paths
(IEEE, 2015)In this paper, we present a new knife-edge diffraction method based on Bullington method for the terrestrial line-of-sight (LOS) paths. The diffraction loss of our new knife-edge diffraction method is compared with the ... -
Full‐brain coverage and high‐resolution imaging capabilities of passband b‐SSFP fMRI at 3T
(Wiley‐Liss, Inc., 2008)Passband balanced-steady-state free precession (b-SSFP)fMRI is a recently developed method that utilizes the passband(flat portion) of the b-SSFP off-resonance response to measureMR signal changes elicited by changes in ... -
Future outlook
(Springer, 2019-01)In this final Chapter, we present a future perspective for the light source design. We discuss the existing problems and briefly introduce new material systems and device architectures that can overcome the current issues. -
How to design quality light sources with discrete color components
(Springer, 2019-01)White light sources using discrete emitters require careful design and optimization. The first step of the design should be determining the intended use of the light source so that application specific requirements can be ... -
Common white light sources
(Springer, 2019-01)In this Chapter we describe the features of common light sources. We first present the spectral features of the sun and discuss its colorimetric properties. Next, we summarize the properties of traditional light sources ... -
Metrics for light source design
(Springer, 2019-01)In this part of this brief, we summarize the metrics that need to be considered for designing light sources. We start with metrics on the shade of color and then continue with color rendering and photometry. -
Colorimetry for LED lighting
(Springer, 2019-01)In this Chapter, we explain the basics of colorimetry and introduce the colorimetric tools useful for designing light sources. -
Light stimulus and human eye
(Springer, 2019-01)In this Chapter, we summarize the structure of the human eye and introduce the sensitivity functions of various photoreceptors and present the visual regimes and corresponding eye sensitivity functions. -
The biobjective multiarmed bandit: learning approximate lexicographic optimal allocations
(TÜBİTAK, 2019-03)We consider a biobjective sequential decision-making problem where an allocation (arm) is called ϵ lexicographic optimal if its expected reward in the first objective is at most ϵ smaller than the highest expected reward, ... -
Effects of the AlN nucleation layer thickness on the crystal structures of an AlN epilayer grown on the 6H-SiC substrate
(Taylor & Francis, 2019-04-08)The influence of the LT-AlN(NL) growth times on the mosaic structure parameters of the AlN layer grown on the LT-AlN(NL)/6H-SiC structures as well as the dislocation densities and the strain behaviours in the AlN epilayers ... -
Investigation of electronic and optical properties of wurtzite MgZnO using GGA + U formalism
