The band structure of two-dimensional chalcogenide glass photonic crystal of triangular lattice structure is calculated at terahertz frequencies using Plane Wave Expansion Method. The band gap ratio was found to vary with variation of the structural parameters such as fill factor and dielectric contrast. The spatial asymmetry associated with lattice structure gives rise to a complete photonic b...

This paper presents a simple and effective method to fabricate a polydimethyl-siloxane (PDMS) microlens array with a high fill factor, which utilizes the UV proximity printing and photoresist replication methods. The concave microlens array mold was made using a printing gap in lithography process, which utilizes optical diffraction of UV light to deflect away from the aperture edges and produc...

Bidisperse granular mixtures in spherical tumblers segregate into three bands: one at each pole and one at the equator. For low fill levels, large particles are at the equator; for high fill levels, the opposite occurs. Segregation is robust, though the transition depends on fill level, particle size, and rotational speed. Discrete element method simulations reproduce surface patterns and revea...

Achieving a high fill factor is a bottleneck problem for capturing high-quality images. There are hardware and software solutions to overcome this problem. In the solutions, the fill factor is known. However, this is an industrial secrecy by most image sensor manufacturers due to its direct effect on the assessment of the sensor quality. In this paper, we propose a method to estimate the fill f...

In previous work I argued against (i) the likelihood of finding a theoretically sound foundation for the linked/convergent distinction and (ii) the utility of the distinction even if a sound theoretical basis could be found. Here I subject Douglas Walton’s comprehensive discussion of the linked/convergent distinction found in Argument Structure: A Pragmatic Theory to careful scrutiny and argue ...

Previous studies that have examined the relationship between implicit and explicit motive measures have consistently found little variance overlap between both types of measures regardless of thematic content domain (i.e., power, achievement, affiliation). However, this independence may be artifactual because the primary means of measuring implicit motives--content-coding stories people write a...

A reliability-based design for the improvement of earth-fill dams is created in this study, and the effect of the improvement of the embankment is evaluated for the safety of the embankment against earthquakes. An inclined core is considered here as the means of improvement for the earth-fill embankment. To evaluate the stability of earth-fill dams, the elasto-viscoplastic finite element method...

In the past twenty years, CCD sensor technology has made significant progress in increasing resolution and improving low-light performance by hardware. However due to physical limits of the sensor design and fabrication, fill factor has become the bottle neck problem for improving quantum efficiency of CCD sensor in order to widen dynamic range of output image. In this paper we propose a novel ...
