P. Premaratne, Human Computer Interaction Using Hand Gestures, Cognitive Science and Technology, DOI 10.1007/978-981-4585-69-9_2, © Springer Science+Business Media Singapore 2014 The history of hand gesture recognition for computer control started with the invention of glove-based control interfaces. Researchers realized that gestures inspired by sign language can be used to offer simple comman...

This expository paper traces the development of the Newton-Raphson method for solving nonlinear algebraic equations through the extant notes, letters, and publications of Isaac Newton, Joseph Raphson, and Thomas Simpson. It is shown how Newton's formulation differed from the iterative process of Raphson, and that Simpson was the first o give a general formulation, interms of fluxional calculus,...

In this paper we suggest that historical studies of technology can help us to account for some, perplexing (at least for traditional economic reasoning) features of open source software development. When looked in historical perspective, open source software seems to be a particular case of what Robert Allen has termed “collective invention”. We explore the interpretive value of this historical...

The authors present the development of the concept of mental disease and treatment in Serbian medicine. Serbian medieval medicine did not acknowledge fortune telling, sorcery, the use of amulets and magical rituals and formulas. These progressive concepts were confirmed by the Church and the Serbian state in what is known as Dusan's Code. The Historical data on the establishment of the first ps...

In studying the history of the construction of artificial limbs to sub­ stitute for lost legs, which has been transmitted to us by written words, objects of art and handicraft, objects found in excavations, and so forth, and learning of the development of the artificial leg through the centuries, one gains knowledge of the foundation on which modern prosthetics is based. Such an historical revi...

When described more than 40 years ago, Klinefelter's syndrome (small testes, sterility, increased excretion of follicle-stimulating hormone, and usually gynecomastia) was thought to be an endocrine disorder. A second testicular hormone was postulated but has never been isolated. During the ensuing years, the syndrome has been found to be a chromosomal disorder, in which there is an extra X chro...

DNA microarrays were first described in 1995 for simultaneous analysis of a large-scale gene expression patterns. Since then, they have moved to center stage in many areas of biological research and now assuming an increasingly important role in diagnostics, genomics, pharmacology, cancer and other biomedical research, among others. In this article, we discuss the scientific background and prin...

Since the ancient times, man was faced with the problem of fracture treatment, which is first described in the records from ancient Egypt. Ever since, many treatment methods have been developed, but the real revolution in the fracture treatment was achieved by internal fixation. Since it was described for the first time, at the end of the 18th century, this method has continuously developed, bu...
