Internship should not just introduce the students to a future professional role, but is also obliged to live up to the requirements of the Swedish Higher Education Act (SFS 1992:1434) for scientific methods and scholarly activities as well as stimulate a critical and reflective attitude. In order for internships to reach higher education standard, not only must there be students, who through th...

Shape recovery is a basic problem in computer vision. Shape from shading (SFS) is an approach to get the 3D shape from a single shading image. Diffuse model is usually used to approximate the surface reflectance property. For specular surfaces, however, it is not suitable. In this paper, we propose a new SFS approach for specular surfaces. The Blinn-Phong reflectance model is applied to charact...

The present study is an attempt to discover the relationships among reflection, role stressors and resilience. To this end, a mixed-method approach was adopted. In the quantitative phase, 122 EFL teachers completed three questionnaires namely English Language Teaching Reflection Inventory, Teacher Role Stressors Scale and Connor-Davidson Resilience Scale. The results of correlation indicated th...

In the present paper, the problem of light reflection from a birefringent medium and thin film is considered. First, the analytical equations governing the propagation of a plane and harmonic electromagnetic wave in an infinite, birefringent, linear, non-dispersive, non-absorbing, and non-magnetic medium is derived from Maxwell equations. Then, using phase matching condition and boundary condit...

In this paper, the problem of simultaneous wavelet estimation and deconvolution is investigated with a Bayesian approach under the assumption that the reflectivity obeys a Bernoulli-Gaussian distribution. Unknown quantities, including the seismic wavelet, the reflection sequence, and the statistical parameters of reflection sequence and noise are all treated as realizations of random variables ...

Devices formed from magneto-inductive waveguides based on coupled loop resonators are considered using simple analytic theory, initially assuming lossless propagation and nearestneighbour coupling. Two-port devices that were considered include mirrors, Fabry–Perot resonators, Bragg gratings and tapers, while more general N-port devices include power splitters and directional couplers. Condition...

In this manuscript, a simple synthesis method of single square loop frequency selective surface (SSLFSS) is discussed, which may find the suitable application in the fast analysis and fabrication of the frequency-selective surface. The presented technique is used to design SSLFSS at 3 GHz, 15 GHz, 22GHz and 26GHz. At every frequency of interest, the analytical result is very close to the requir...

Back-scattering darkfield (BSDF), epi-fluorescence (EF), interference reflection contrast (IRC), and darkfield surface reflection (DFSR) are advanced but expensive light microscopy techniques with limited availability. Here we show a simple optical design that combines these four techniques in a simple low-cost miniature epi-illuminator, which inserts into the differential interference-contrast...
