This paper presents the novel Rao-Blackwellised particle filter (RBPF) for mobile robot simultaneous localization and mapping (SLAM) using monocular vision. The particle filter is combined with unscented Kalman filter (UKF) to extending the path posterior by sampling new poses that integrate the current observation which drastically reduces the uncertainty about the robot pose. The landmark pos...

So effectively, you can say that the capacitor acts as a low-pass filter when it in a transistor circuit, it blocks the DC and acts as a low impedance path for AC. Official Full-Text Publication: Single Transistor Active Filters: What is Possible and The results presented here fill both a circuit-theoretic gap and an application-oriented gap related to single a case is the low-pass filter numbe...

A highly-scaleable FIR architecture based on the radix-4 Booth algorithm has been designed with scaleable dynamic ranges of input data and filter coefficients. The radix-4 Booth algorithm is demonstrated to have a lower hardware complexity and a fair throughput rate than the other radix approaches. In order to achieve scaleability, the configurable-connection function between latches of input d...

In the IEEE 802.11a WLAN standard, orthogonal frequency division multiplexing (OFDM) modulation is employed. Diversity techniques are effective way to overcome multipath fading in the OFDM systems. A fractional sampling (FS) scheme is one of the diversity techniques with a single antenna. Through FS it is possible to separate multipath components and obtain diversity gain in OFDM. Though FS has...

With the rapid increase of RDF data, the SPARQL query processing has received much attention. Currently, most RDF databases store RDF data in a relational table called triple table and carry out several join operations on the triple tables for SPARQL query processing. However, the execution plans with many joins might be inefficient due to a large amount of intermediate data being passed betwee...

This work considers automated multi target tracking of odontocete whistle contours. An adaptation of the Gaussian mixture probability hypothesis density (GM-PHD) filter is described and applied to the acoustic recordings from six odontocete species. From the raw data, spectral peaks are first identified and then the GM-PHD filter is used to simultaneously track the whistles' frequency contours....

understanding of the runoff generation processes is important in understanding the magnitude and dynamics ofgroundwater discharge. however, these processes continue to be difficult to quantify and conceptualize. in this study,two digital filter based separation modules, the recursive filtering method (rdf) and a generalization of therecursive digital filter (grdf) were1991–2002 in the hableh ro...

In 2015, Barber and Candès introduced a new variable selection procedure called the knockoff filter to control the false discovery rate (FDR) and prove that this method achieves exact FDR control. Inspired by the work of Barber and Candès (2015), we propose and analyze a pseudoknockoff filter that inherits some advantages of the original knockoff filter and has more flexibility in constructing ...
