We present the Source Code History Navigator, a tool for visualizing the evolution of source code and comparing many revisions of a source code file. Our tool provides an overview of the entire history of a source file through a “history flow”-style visualization in which revisions are plotted as vertical pixel stripes, with each pixel line in a stripe corresponding to a line in the revision an...

obtaining a continuous source of normal cells or dna from a single individual has always been a rate limiting step in biomedical research. availability of lymphoblastoid cell lines (lcls) as a surrogate for isolated or cryopreserved peripheral blood lymphocytes has substantially accelerated the process of biological investigations. lcls can be established by in vitro infection of resting b cell...

The proof of principle of the Laser Ion Source Trap (LIST) coupled to a gas cell catcher system has been demonstrated at the Leuven Isotope Separator On-Line (LISOL). The experiments were carried out by using the modified gas cell-based laser ion source and the SextuPole Ion Guide (SPIG). Element selective resonance laser ionization of neutral atoms was taking place inside the cold jet expandin...

An infinite row of periodically spaced, identical rigid circular cylinders is excited by an acoustic line source, which is parallel to the generators of the cylinders. A method for calculating the scattered field accurately and efficiently is presented. When the cylinders are sufficiently close together, Rayleigh–Bloch surface waves, which propagate energy to infinity along the array are excite...

A real-time, face tracker based on both sound and visual cues is presented. Initial talker locations are estimated acoustically from microphone array data while precise localization and tracking are derived from visual data. The image processing employs a hierarchical structure which utilizes source motion, contour geometry, color data, and facial features. The resulting system is capable of tr...

A previously developed method to place a quasi-null in a specified angular position of the near-field line source in sum patterns while, simultaneously, the far-field sidelobe level is maintained under a desired value, is shown to be applicable to linear Bayliss patterns as well. This method, as in the previous work, is performed through the use of the Simulated Annealing technique, which allow...

Hybrid source models for fricative consonants are derived based on aeroacoustic principles of sound generation employing vocal tract area functions obtained from magnetic resonance imaging data of voiced and unvoiced English fricatives. Results based on data from a male and a female subject indicate that a linear source-filter model is fairly adequate for capturing essential spectral characteri...

For an attractive trapped Bose-Einstein condensate an imaginary three-body recombination loss term and an imaginary linear source term are usually included in the Gross-Pitaevskii ~GP! equation for a proper account of dynamics. Under the action of an impulsive force, generated by suddenly changing the atomic interaction or the trapping potential, the solution of this complex GP equation for att...
