In this paper an efficient algorithm is proposed for person identification based on the analysis of 2D images of a designed mask projected onto the person's face in a cooperative environment. The cooperative environment is essential for the accomplishment of the images under a certain condition. The importance of the designed mask is for avoiding the complexity of feature selection from the fac...

Inspired by the discussion in most recent neurological research about the role of callosal fiber connections with respect to brain asymmetry [1, 2] we developed a technique that can measure distances between brain hemispheres in a non-Euclidean, curvilinear space. The new technique is a generic morphometric tool for measuring minimal distances within and across 3-D structures, but the project d...

An incremental learning for the feature extraction of OCR was applied to the learning of multiple filter mask in the feature extraction. The multiple filter mask means plural masks which are used for one local region of an input pattern. The output of the filter is provided to a recognition unit as a feature vector. In the recognition unit, distance is calculated by a reference vector and the f...

In the past 20 or so years there has been much research interest in the evolution of cooperation in humans (Axelrod, 1995; Boyd & Richerson, 1992; Fehr & Fischbacher, 2003; Milinski et al., 2002; West et al., 2006). The foundational problem addressed by this work is how cooperation can remain evolutionarily stable when individuals have incentives to freeride; that is, to take but not contribute...

A new fabrication technique based on etching is employed to convert a copper foil into a porous structure with an array of micron size pores. The motivation stems from the need to develop a more efficient and controllable gas diffusion medium for fuel cell applications. The influence of mask shape, mask width and etching time was investigated experimentally. A correlation to predict trench widt...

This paper describes a system for sub-pixel registration of mask and opacified digital X-ray images so that the mask image can be accurately subtracted out from the opacified image. Our technique results in digital subtraction angiograms (DSAs) with fewer artifacts and better contrast.

The COVID-19 pandemic presented the medical education community with unprecedented challenges. Little is known about impact of on professional identity formation (PIF) in matriculating students. objective this study to explore PIF a cohort first-year students using mask-making and narrative reflection. This took place spring 2021. Following IRB approval, Penn State College Medicine’s University...

This paper is a part of a project concerning the finding of objective characteristics of susceptibility to voice strain. In that project, measurements were made of simultaneous recordings of microphone speech, oral flow, oral pressure and EGG. A comparison is made of parameters extracted from the inverse filtered waveforms of oral flow and speech pressure from these recordings, that is, with an...
