background and objective: obstructive sleep apnea (osa) is the most common type of sleep-disordered breathing. multivariable apnea prediction (map) index consists of three questions about the frequency of osa symptoms plus body mass index (bmi), age and sex that categorizes the patients to low and high risk for osa using a formula. objective map index was calculated by discounting the questions...

Abstruct This paper presents the framework for creating of 3D map. The 3D shape and the textures of a building are acquired by analyzing moving picture taken from a running vehicle. However, in the real city environment, it is difficult to obtain 3D data of buildings accurately, because the slight motion of images due to the vehicle motion cannot be removed completely. This paper describes a ap...

In this paper, constructing the improved chaotic map which multiplies output value of by a large value, and subtracts its integer part. Simulation results show that chaos range is enlarged. The generated sequence has strong randomness. A double image encryption algorithm proposed combining maps with permutation diffusion structure. can reduce complexity while ensuring effect. simulation resist ...
