Regarding doming of AK mask, many investigations have been made so far. The mechanical design looks almost at the limit. Curvature design of the mask is a key point. The subject is discussed from the panel curvature point of view and a new panel curvature function that is advantageous for mask design is proposed

Artists often want to change the colors of an image to achieve a particular aesthetic goal. For example, they might limit colors to a warm or cool color scheme to create an image with a certain mood or feeling. Gamut masking is a technique that artists use to limit the set of colors they can paint with. They draw a mask over a color wheel and only use the hues within the mask. However, creating...

We present a new approach for resolving occlusions in augmented reality. The main interest is that it does not require 3D reconstruction of the considered scene. Our idea is to use a contour based approach and to label each contour point as being “behind” or “in front of”, depending on whether it is in front of or behind the virtual object. This labeling step only requires that the contours can...

Lying supine, the technician uses my mask to bolt me to the treatment table. After he leaves the room, I feel alone, and at first, afraid. I see and hear the radiation machine move around me, but feel nothing. Minutes later, the door opens, and the mask is unbolted. This process is repeated almost daily for 2 months... After 2 weeks, the skin on my neck and inside my mouth becomes red, sore, an...

The similarity of the letters in the Latin alphabet has been measured numerous times using a variety of methodologies and stimuli. We provide a comprehensive review of past attempts to construct similarity spaces of the Latin alphabet, and determine that accuracy has frequently been attributed to a subset of three common sources: perceivability, bias, and similarity. We present the results of t...

The present study evaluated the efficacy of disposable surgical masks as a microbial barrier with 95% of Bacteria Filtration Efficacy (BFE) according to the wearing time (1, 2, 4 and 6 hours). The masks showed a decrease in efficacy after a 4-hour wearing time.

We present an explicit formula for the mask of odd points n-ary, for any odd n 3, interpolating subdivision schemes. This formula provides the mask of lower and higher arity schemes. The 3-point and 5-point a-ary schemes introduced by Lian, 2008, and 2m 1 -point a-ary schemes introduced by, Lian, 2009, are special cases of our explicit formula. Moreover, other well-known existing odd point n-ar...

In this paper, we present a method that we call on-surface convolution which extends the classical notion of a 2D digital filter to the case of digital surfaces (following the cuberille model). We also define an averaging mask with local support which, when applied with the iterated convolution operator, behaves like an averaging with large support. The interesting property of the latter averag...

This contribution discusses the information leakage of flipflops for different DPA-resistant logic styles. We show that many of the proposed side-channel resistant logic styles still employ flip-flops that leak data-dependent information. Furthermore, we apply simple models for the leakage of masked flip-flops to design a new attack on circuits implemented using masked logic styles. Contrary to...

We use the PSCz IRAS galaxy redshift survey to analyze the cosmological galaxy dipole out to a distance 300 h Mpc. The masked area is filled in three different ways, firstly by sampling the whole sky at random, secondly by using neighbouring areas to fill a masked region, and thirdly using a spherical harmonic analysis. The method of treatment of the mask is found to have a significant effect o...
