This paper presents some interesting results obtained by the algorithm by Bauer, Der and Hermann (BDH) [1] for magnification control in Self-Organizing Maps. Magnification control in SOMs refers to the modification of the relationship between the probability density functions of the input samples and their prototypes (SOM weights). The above mentioned algorithm enables explicit control of the m...

We see currently the trend of having larger and larger displays in our living rooms and that more and more computer oriented applications which are usually controlled by a mouse are displayed by them. Examples for the latter are web browsing, picture browsing, chatting and email. This leads to two problems. Firstly, most applications and web pages are not designed for situations in which the us...

Since the beginning of applications non-destructive testing/evaluation (NDT/NDE) techniques, efforts have been made consistently to improve their detection sensitivity and resolution. In present paper, factors governing lateral resolution in three major NDT viz., ultrasonic testing (UT), x-ray radiographic (XRT), eddy current (ECT) are presented. Furthermore, a review recent advances these tech...

The twin of this paper, “Forbidden Magnification? I.” [1], presents systematic SOM simulations with the explicit magnification control scheme of Bauer, Der, and Herrmann [2] on data for which the theory does not guarantee success, namely data that are n-D, n > 2 and/or data whose components in the different dimensions are not statistically independent. For the unsupported n = 2 cases that we in...

Digital templating with external calibration markers is the standard method for planning total hip arthroplasty. We determined the geometrical basis of the magnification effect, compared magnification with external and internal calibration markers, and examined the influence on magnification of the position of the calibration markers, patient weight, and body mass index (BMI). A formula was der...

Abstract Dental radiography is an important diagnostic tool for the detection and assessment of extent dental caries accurate treatment planning. There no safe limit X-ray exposure. The associated risks exposure are higher in children due to a rate cell proliferation them, compared with adults. This study aimed assess genotoxic cytotoxic effects radiographic modalities on buccal mucosal cells c...
