This paper presents the WANDA Workbench, which is an open framework for electronic data processing. The framework provides generic interfaces for ’plugin’ applications for graphical user interfaces (client desktop with client plug-ins) and processing modules (server with server plug-ins). The applied plug-in concept allows for the functional extension of the workbench without changing the frame...

Automatic person identification is one of the major concerns in this era of automation. However, this is not a new problem and our society has adopted several different ways to authenticate the identity of a person such as signature and possessing a document. With the advent of electronic communication media (Internet), the interactions are becoming more and more automatic and thus the problem ...

Currently, writer’s soft-biometrics prediction is gaining an important role in various domains related to forensics and anonymous writing identification. The purpose of this work is to develop a robust prediction of the writer’s gender, age range and handedness. First, three prediction systems using SVM classifier and different features, that are pixel density, pixel distribution and gradient l...

Can skilled performers, such as artists or athletes, recognize the products of their own actions? We recorded 12 pianists playing 12 mostly unfamiliar musical excerpts, half of them on a silent keyboard. Several months later, we played these performances back and asked the pianists to use a 5-point scale to rate whether they thought they were the person playing each excerpt (15 no, 55 yes). The...

Background: Huntington’s Disease (HD) is characterized by choreatic movements. Chorea is treated with antidopaminergic neuroleptics like tiaprid and tetrabenazine. Especially in patients with signs of parkinsonism antidopaminergic medication often leads to a worsening of symptoms. In earlier studies valproic acid showed no beneficial effect on involuntary movements. Myoclonus is rare in HD and ...

Both electronic note-taking (typing) and traditional note-taking (handwriting) are being utilized by college students to retain information. The effects of the method of notetaking and note-taking context were examined to determine if handwriting or typing notes and whether a lecture context or a textbook-reading context influenced retention. Pitzer College and Scripps College students were ass...

Handwriting letters has been shown to increase Blood Oxygen Level Dependent (BOLD) signal during letter perception in visual and motor brain regions relative to other types of training in preschool children. However, co-activation in these regions speaks neither to the presence of functional connections between them nor to the experiences by which such connections might be established. We inves...

Legal literature and case law depicts the infamous conviction of Alfred Dreyfus for treason and espionage in 1894 as a prime example of the irresistible power of even grossly fallacious mathematical demonstrations to overwhelm a legal tribunal. This essay shows that Dreyfus is not a case of mathematics run amok, unchecked and uncomprehended. To the contrary, the defects in the mathematical proo...

Multiple personality disorder has been associated with marked psychophysiologic alterations ever since careful clinical observations have been made on this perplexing disorder. Physical symptoms known to be associated with multiple personality include headaches, conversion symptoms, changes in voice, seizure-like activity, unexplained pain or insensitivity to pain, alterations in handedness or ...

Analysis of scripts plays an important role in paleography and in quantitative linguistics. Especially in the field of digital paleography quantitative features are much needed to differentiate glyphs. We describe an elaborate set of metrics that quantify qualitative information contained in characters and hence indirectly also quantify the scribal features. We broadly divide the metrics into s...
