the infomax algorithm is a popular method in blind source separation problem. in this article an extension of the infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-gaussian distributions. this ability is the results of using two different nonlinear functions and new coefficients in the learning rule. in this paper we show how we can use the distribution...

We present a general method for blind image deconvolution using Bayesian inference with super-Gaussian sparse image priors. We consider a large family of priors suitable for modeling natural images, and develop the general procedure for estimating the unknown image and the blur. Our formulation includes a number of existing modeling and inference methods as special cases while providing additio...

Hospitals can be confusing environments for patients and their family members to navigate, especially when they are feeling exhausted, stressed, overwhelmed, or all of the above. When they need help in their rooms, inpatients often resort to the only resource they are aware of: the call bell. Nurses are frequently called to perform non-nursing tasks, such as ordering food, changing room tempera...

Through out the design process, designers have to consider the needs of potential users. This is particularly important, but rather harder, when the designers interact with the artefact to-be-designed using different senses or devices than the users, for example, when sighted designers are designing an artefact for use by blind users. In such cases, designers have to ensure that the methods use...

statement of problem: blindness as a disability seems to produce difficulties to reach an ideal heath status of the teeth. moreover ordinary educational health programmes for this group of population, especially children, are not successful. purpose: investigate the dental health status of these children and to see if they are really different with the normal population. materials and methods: ...

Objective: The present study aimed at investigating the relationship between attachment styles and self-efficacy in blind and non-blind female high school students in Tehran. Methods: The statistical population consisted of all female students studying in grades one or two in Tehran girl’s high schools, in the academic year 2014. The study design was causal-comparative, conducted on 120 ...
