We present a real-time rendering algorithm that generates soft shadows of dynamic scenes using a single light sample. As a depth-map algorithm it can handle arbitrary shadowed surfaces. The shadow-casting surfaces, however, should satisfy a few geometric properties to prevent artifacts. Our algorithm is based on a bivariate attenuation function, whose result modulates the intensity of a light c...

This paper describes an advanced sonar ring that employs a low receiver sample rate to achieve processing of 48 receiver channels at near real time repetition rates of 15 Hz. The sonar ring sensing covers 360 degrees around the robot with simultaneously firing of 24 transmitters. The receiver sampling frequency is 250 kHz, compared to previous work at 1 MHz, firstly to maximize the speed of pro...

In this vignette, we demonstrated the application of RnaSeqSampleSize as an sample size estimation tool for RNA-seq data. A user friendly web interface is also provided at http: //cqs.mc.vanderbilt.edu/shiny/RnaSeqSampleSize/ for researchers not familar with R. RnaSeqSampleSize package provides the following features: • Estimation of sample size or power by single read count and dispersion; • E...

In this paper, we propose an HMM trajectory-guided, real image sample concatenation approach to photo-real talking head synthesis. It renders a smooth and natural video of articulators in sync with given speech signals. An audio-visual database is used to train a statistical Hidden Markov Model (HMM) of lips movement first and the trained model is then used to generate a visual parameter trajec...

A scalable real-time asynchronous sample rate converter software kernel is presented that offers a flexible alternative to the usual hardware implementations. The kernel is dynamically configurable at run-time and supports almost arbitrary up-sampling or down-sampling ratios and any number of channels. Due to its scalability this sample rate converter kernel may be used both for low complexity,...

We demonstrate a real-time transient waveform digitizer with a record 1 TSa/s (TeraSample/sec) sampling rate. This is accomplished by using a photonic time stretch preprocessor which slows down the electrical waveform before it is captured by an electronic digitizer. * Present address: College of Optics and Photonics: CREOL & FPCE, University of Central Florida, 4000 Central Florida Blvd., Orla...

using a sample fiom burr type xu distribution, bayes prediction intervals are derived for the maximum and minimum of a future sample fromthe same distribution, but in the presence of a single outlier of the type 8,8. the prior of q is assumed to be the gamma conjugate. a real example is given to illustrate the procedure. also, the comparison between the values of the prediction bounds for diffe...
