ESports tournaments, such as Dota 2’s The International (TI), attract millions of spectators to watch broadcasts on online streaming platforms, to communicate, and to share their experience and emotions. Unlike traditional streams, tournament broadcasts lack a streamer figure to which spectators can appeal directly. Using topic modelling and crosscorrelation analysis of more than three million ...

Generalized Discrete Fourier Transform (GDFT) with nonlinear phase is a complex valued, constant modulus orthogonal function set. GDFT can be effectively used discrete multi-tone (DMT), orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA) communication systems. The constant modulus transforms like discrete Fourier transform (DFT), Walsh transform, and Gold ...

In this report, we present a novel feature detection technique for unstructured point clouds. We introduce a generalized concept of geometric features that detects locally uniquely identifiable keypoints as centroids of area with locally minimal slippage. We extend the concept to multiple scales and extract features using multi-scale mean shift clustering. In order to validate matches between f...

In this paper, we investigate cross-correlations between nonferrousmetal spot and futures markets using detrended cross-correlation analysis (DCCA). We find the existence of significant cross-correlations for both return and volatility series. The DCCA-based crosscorrelation coefficients are very high and decrease with the futures maturity increases. Using the multifractal extension of DCCA, th...

A generalized version of the information matrix is introduced consisting of the autocorrelation and crosscorrelation matrices of the shifted input and output data. Based on the concept of data correlation, a new system realization algorithm is developed to identify a model directly from input and output data. The algorithm starts with computing the information matrix to derive a special correla...

Seven methods for endoscopic motion compensation for laryngeal high-speed videoendoscopy (HSV) are compared. Two of them are based on tracking the maximum of the crosscorrelation function of two images; two are based, respectively, on the minimization of the L2–norm and the magnitude difference distance between two images; and the other three utilize properties of the FFT-based cross-power spec...

We study stock market instability by using cross-correlations constructed from the return time series of 366 stocks traded on the Tokyo Stock Exchange from January 5, 1998 to December 30, 2013. To investigate the dynamical evolution of the cross-correlations, crosscorrelation matrices are calculated with a rolling window of 400 days. To quantify the volatile market stages where the potential ri...

During the last decade, several young stellar associations have been discovered within 100 pc of Earth (see [18] for a recent review) thanks to the crosscorrelation of the ROSAT and Hipparcos catalogues, combined with spectroscopy observations. The stars belonging to these young local associations (herafter, YLA) have ages in the range from a few to several tens of Myr. The YLA not only offer i...

Surface modification with polyethylene glycol (PEG; PEGylation) is a widely used technique to improve nanoparticle (NP) stability, biocompatibility, and biodistribution profiles. In particular, PEGylation of silica surfaces and coatings plays a pivotal role across various classes of NPs. Despite the use of numerous protocols there is limited fundamental understanding of the mechanisms of these ...

DS-CDMA has been recognized as the major candidate for providing high and variable data rates in third generation wireless networks, where multi-code structures and different spreading gains will be employed. In this paper, we address the problem of assignment of variable spreading gain deterministic codes to a set of users, with the objective to maximize down-link system throughput. We propose...
