Cyclic redundancy checks (CRCs) are commonly used to detect errors from noise in networks. They also have been used to verify the integrity of files in a system to prevent tampering and suggested as a possible algorithm for manipulation detection codes. It has been known that a CRC will not detect all errors but with random noise it is unlikely. But a malevolent adversary can efficiently modify...

Adults (N = 336) 18 to 54 years old watched a television program containing violence, sex, both violence and sex, or no violence and sex. Programs were shown in a comfortable room containing padded chairs and tasty snacks. Each program contained the same 12 ads. Embedding an ad in a program containing violence or sex reduced (a) viewers' likelihood of remembering the advertised brand, (b) their...

Twelve athletes, who routinely used plyometric exercises, performed drop jumps from 46 cm in water, on padded (5 cm thick wrestling mat), and unpadded conditions. GRF obtained via force platform and video analysis of markers placed along the leg were used to compare contact time (CT), flight time (FT), jump height calculated from flight time (JHFT) and video data (JHVIDEO), and reactive strengt...

We describe a modified fulcrum design to overcome limitations of a traditional fulcrum. The modified fulcrum is a triangular prism-shaped foam with rounded and padded edges. The 3 faces of the fulcrum represent 3 different heights (17.0 cm, 17.5 cm, and 21.0 cm). For fulcrum bending radiographs of the thoracic curve, the patient is placed on an X-ray table in a lateral decubitus position over t...

INTRODUCTION The course of wound healing in high-risk patients with diabetes, particularly those with peripheral arterial disease and renal failure, is often prolonged and fraught with complications. Traditional methods of offloading the posterior foot or holding correction in place following diabetic foot reconstruction include various padded and bolstering devices. METHODS In this article, ...

In this paper, variable block length based character/bit level transformation has been proposed for encryption and decryption, where a block of characters /few bits has taken into account. The originated text is transformed into decimal values and passed to encoder module. In this module values are cluttered using binary operations present in most systems with keys. This routine is based on fei...

To allow for a computationally efficient equalization scheme for the frequencyselective transmission channels encountered in wireless local area network (WLAN) applications, cyclic prefix (CP) block transmission schemes have been proposed, such as single-carrier CP (SC-CP) and multi-carrier CP (MC-CP) transmission, also known as orthogonal frequency division multiplexing (OFDM). In this letter,...

The goal of this contribution1 is twofold: i) an overview on the vast literature on recent advances related to OFDM modulators is given: Cyclic-Prefix OFDM, Zero-Padded OFDM, PseudoRandom-Postfix OFDM and IOTA-OFDM; these are identified to be potential candidates for fourth generation mobile communication networks in the framework of the IST-WINNER project. ii) The advantages/disadvantages of t...

In this paper, first we point out some flaws in the existing indifferentiability simulations of the pf-MD and the NMAC constructions, and provide new differentiable attacks on the hash functions based these schemes. Afterthat, the indifferentiability of the 20 collision resistant PGV hash functions, which are padded under the pf-MD, the NMAC/HMAC and the chop-MD constructions, are reconsidered....

Figure 1: Basic topological patterns used for quadrangulating rectangular and triangular regions. Vertices with a red circle represent corners. Vertices with orange and blue fill represent irregular vertices with valence three and five, respectively. pX and pY represent a regular grid of quadrilaterals padded to the corresponding side of the rectangle (only shown with pattern 1 for brevity). pB...
