A novel approach to image coding using off-line foveation controlled by multiple eye-tracking measurement

In this paper we investigate the feasibility of using a wavelet transform to compress individual frames in a video sequence controlled by points of gaze coordinates collected from different viewers by an eye-tracker. Unlike most eye-tracking controlled compression approaches, we make the compression "off-line" and not in real time. Our results indicate that the distribution of gaze-points is "comp

Functionally involved cell surface antigens on murine lymphokine activated killer cells

To investigate the possible involvement of some cell surface structures on lymphoid cells in the functional activity of lymphokine activated killer (LAK) cells, a number of monoclonal antibodies (Mab) against such structures was studied for their ability to inhibit LAK activity in a standard cytotoxicity assay against the natural killer-insensitive target cell EL-4. Almost complete inhibition of L

Monasticism and the Philosophical Heritage

Abstract in Undetermined This article examines the rise of monasticism in Late Antiquity. It reveals the close link between traditional Greek society and culture and the rise of monasticism, based on historical evidence and the literary character of the early monastic texts. While not denying the innovative character of much of early monastic life, the rich variety of forms of monasticism, and the

Photobiology — The science of life and light, 2nd ed.

Photobiology: The Science of Life and Light, Second edition, is fully updated and offers eight new chapters for a comprehensive look at photobiology. The chapters cover all areas of photobiology, photochemistry, and relationship between light and biology, each with up-to- date references.The chapter authors (of which seven are new) have very different backgrounds, and have produced a truly cross-d

Higher-Order Neural Network Based Root-Solving Controller for Adaptive Tracking of Stable Nonlinear Plants

The use of Intelligent control schemes in Nonlinear Model Based Control (NMBC) has gained widespread popularity. Neural Networks, in particular, have been used extensively to model the dynamics of nonlinear plants. However, in most cases, these models do not lend themselves to easy maneuvering for controller design. Therefore, a common need is being felt to develop intelligent control strategies t

Mapping activities of artists in the past: A bibliometric study of the library of the Scandinavian Association in Rome to 1870

The purpose of this study is to conduct a bibliometric analysis of the library collection at the Scandinavian Association in Rome. Data were gathered from the library catalog and then submitted to frequency and co-occurrence analyses. By examining keywords, authors, and the language of the books found in the library, we were able to draw conclusions about its role as a social rather than an academ

Simulation of robot paths and heat effects in welding

Popular Abstract in Swedish Svetsning är en av de viktigaste tillämpningarna för robotar är inom tillverkningsindustrin. Normalt så programmeras roboten genom att operatören guidar manuellt robotarmen mellan de olika robotkoordinaterna. För att förbättra noggrannheten vid programmeringen kan man använda ett simuleringsverktyg, så kallat Computer Aided Robotics (CAR). Simulering kan även vara ett kThe objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. A special interface was created which facilitated information exchange between the two software progra

Logical Knowledge Representation of Regulatory Relations in Biomedical Pathways

Knowledge on regulatory relations, in for example regulatory pathways in biology, is used widely in experiment design by biomedical researchers and in systems biology. The knowledge has typically either been represented through simple graphs or through very expressive differential equation simulations of smaller sections of a pathway. As an alternative, in this work we suggest a knowledge represe
