New techniques for reducing the depth of circuits for cryptographic applications are described and applied to the AES S-box. These techniques also keep the number of gates quite small. The result, when applied to the AES S-box, is a circuit with depth 16 and only 128 gates. For the inverse, it is also depth 16 and has only 127 gates. There is a shared middle part, common to both the S-box and i...

Diffuse optical tomography (DOT) has much lower sensitivity in deep tissues than in superficial tissues, which leads to poor depth resolution. In this paper, a layer-based sigmoid adjustment (LSA) method is proposed for reducing sensitivity contrast in the depth dimension. Using this method, differences in image quality between layers can be effectively reduced. As a result, positioning errors ...

The growing process of building design and construction, regardless of reducing sources of energy, is one of the threats to the environment and human life. Therefore it is necessary that design strategies in new buildings be orientated to the aim of reducing energy consumption and environmental pollution. Earth sheltering is a passive idea that reduces building energy consumption and ensure...

View-based 3D video streaming requires the compression and transmission of depth maps along with the video sequence. The requirements for representing these depth maps include moderately high compression, preservation of depth discontinuities, low complexity decoding, and to be in a form that is suitable for real-time rendering using graphics cards. This motivates a meshbased representation for...

To observe the effects of different acupuncture manipulations on blood pressure and target organ damage in spontaneously hypertensive rats (SHRs), this study used the reinforcing twirling method (1.5-2-mm depth; rotating needle clockwise for 360° and then counter clockwise for 360°, with the thumb moving heavily forward and gently backward, 60 times per minute for 1 minute, and retaining needle...
