introduction: average glandular dose calculation in mammography with mo-rh target-filter and dose calculation for different situations is accurate and fast. material and methods: in this research, first of all, x-ray spectra of a mo target bombarded by a 28 kev electron beam with and without a rh filter were calculated using the mcnp code. then, we used the sobol-wu parameters to write a fortra...

introduction: to write a computational program to calculate the average glandular dose in mammography with rh-rh target-filter and also use it as an accurate and fast method of dose calculation founder different situations. materials and methods: in this research, the sobol-wu parameters are used to write a fortran code for glandular dose calculation in rh-rh target-filter mammograms. the code ...

In 1997, Wu and Wu proposed an improvement of the Chang-Wu broadcasting cryptosystem using geometric properties of lines. The Wu-Wu scheme gave a better performance and required fewer public parameters than the Chang-Wu scheme. In this paper the authors propose an improvement to the Wu-Wu scheme using geometric properties of line. This improvement reduces the computation and significantly decre...

In 1991, Chang and Wu proposed a broadcasting cryptosystem using interpolating polynomials and geometric properties of circles. Nevertheless, the Chang-Wu scheme can be further enforced by using a time-variant parameter and a one-way function to protect legal receivers’ secrets from being disclosed. The authors present an improvement of the Chang-Wu scheme using geometric properties of lines. T...

The mechanisms leading to thermodynamic chaos in the Baxter-Wu model is considered. We compare the Baxter-Wu model with triangular antiferromagnets and discuss the difficulties related to the modeling of thermodynamic chaos by disordered models. We also discuss how to overcome the problem of infinitely many order parameters. Then we consider the Baxter-Wu model in a complex magnetic field and s...

In this paper, the connection between Menger probabilistic norms and H"{o}hle probabilistic norms is discussed. In addition, the correspondence between probabilistic norms and Wu-Fang fuzzy (semi-) norms is established. It is shown that a probabilistic norm (with triangular norm $min$) can generate a Wu-Fang fuzzy semi-norm and conversely, a Wu-Fang fuzzy norm can generate a probabilistic norm.

Lizhen Yang, Xiaoyun Wang, Dong Zheng, Kefei Chen Abstract: In 1988, Harn, Laih and Huang proposed a password authentication scheme based on quadratic residues. However, in 1995, Chang, Wu and Laih pointed out that if the parameters δ β α , , and λ are known by the intruder, this scheme can be broken. In this paper, we presented another attack on the Harn-Laih-Huang scheme. In our attack, it do...
