we present an approach to design of fault tolerant computing systems. in this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. code combining techniques are very effective, which one of these codes are turbo codes. the algorithm-based fault tolerance techniques that to detect errors rely on the c...

We will now consider the problem of creating a set of bitstrings such that the bits are almost k-wise independent. Our method consists of two steps. In the first step we create a set of bitstrings such that parity on every fixed index set is almost even. In the second step we present a method to convert such a set into a set where the bits are almost k-wise independent. For presentational reaso...

The paper presents the results of study into composition and properties milk in black and- white dairy cows improved using black-and-white Holsteins different lines. It has been found that Vis Ideal line produce with a high casein phosphorus content, Poseidon give content whey proteins, Annas Adema lactose calcium content. Milk from is most suitable for production high-quality products such as ...

We consider the parity transformation and the consequences of parity invariance on the n-point correlation function of the cosmic shear, or any other polar (or ‘spin-2’) field. The decomposition of the shear field into Eand B-modes then yields the result that any correlation function which contains an odd number of B-mode shear components vanishes for parity-invariant random shear fields. This ...
