In this paper, a tool able to support the sailing yacht designer during early stage of design process has been developed. Cubic Rational Bézier curves have selected describe main defining hull yacht. The adopted approach is based upon definition set parameters, say length waterline, beam canoe body draft and some dimensionless coefficients according traditional way designer. Some geometrical co...

background:  radiochromic film is used for radiation dose measurement, xr-rv3 is used in fluoroscopy and ebt2 film in radiation therapy. the aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. materials and methods: comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distributio...

In this paper describes the basic idea of elliptic curve cryptography (ECC) as well Vigenère symmetry key. Elliptic arithmetic can be used to develop coding schemes, including key exchange, encryption, and digital signature. The main attraction compared Rivest, Shamir, Adleman (RSA) is that it provides equivalent security for a smaller size, which reduces processing costs. From theorical basic,...
