This paper presents measurements of Radar Cross Section (RCS) five Unmanned Aerial Vehicles (UAVs), comprising both consumer grade and professional small drones, collected in a semi-controlled environment as function azimuth aspect angle, polarization frequency the range 8.2-18 GHz. The experimental setup data pre-processing, which include coherent background subtraction gating procedures, are ...

Credit scoring plays a vital role in the field of consumer finance. Survival analysis provides an advanced solution to credit-scoring problem by quantifying probability survival time. In order deal with highly heterogeneous industrial data collected Chinese market finance, we propose nonparametric ensemble tree model called gradient boosting (GBST) that extends models algorithm. The is learned ...

One approach for understanding the encoding of information by spike trains is to fit statistical models and then test their goodness of fit. The time-rescaling theorem provides a goodness-of-fit test consistent with the point process nature of spike trains. The interspike intervals (ISIs) are rescaled (as a function of the model's spike probability) to be independent and exponentially distribut...

Although Kolmogorov-Smirnov (KS) statistic is a widely used method, some weaknesses exist in investigating abrupt Change Point (CP) problems, e.g. it is time-consuming and invalid sometimes. To detect abrupt change from time series fast, a novel method is proposed based on Haar Wavelet (HW) and KS statistic (HWKS). First, the two Binary Search Trees (BSTs), termed TcA and TcD, are constructed b...

For low-redshift (z < 0.1) Type Ia supernovae (SN Ia) samples used in several cosmological analyses over the past decade, we probe for systematic bias by looking correlations between surface brightness (SB) measurements and Hubble residuals (HR). 292 SNe Ia, measure SB at location of SN from publicly available Pan-STARRS (PS1) images. The are two recent with low-z that overlap PS1 footprint: 1)...

Originating from neutron star–neutron star or star–black hole mergers, short gamma-ray bursts (SGRBs) are the first electromagnetic emitters associated with gravitational waves (GWs). This association makes determination of SGRB formation rate (FR) a critical issue. We determine true FR and its relation to cosmic (SFR). can help in determining expected GW involving small mass mergers. present n...

Reliable identification of targets of bacterial regulators is necessary to understand bacterial gene expression regulation. These targets are commonly predicted by searching for high-scoring binding sites in the upstream genomic regions, which typically leads to a large number of false positives. In contrast to the common approach, here we propose a novel concept, where overrepresentation of th...
