In this project we will discuss about methods of extracting stable features for camera and laser range finder in order to use these features in SLAM. The methods including dot-product feature extractor and line segment feature extractor for laser range finder, corner feature extractor for camera images. The robot platform we work on is the Segway

We propose a strategy for discriminative training of the ivector extractor in speaker recognition. The original i-vector extractor training was based on the maximum-likelihood generative modeling, where the EM algorithm was used. In our approach, the i-vector extractor parameters are numerically optimized to minimize the discriminative cross-entropy error function. Two versions of the i-vector ...

In a recent breakthrough [CZ15], Chattopadhyay and Zuckerman gave an explicit two-source extractor for min-entropy k ≥ log n for some large enough constant C. However, their extractor only outputs one bit. In this paper, we improve the output of the two-source extractor to k, while the error remains n−Ω(1). Our improvement is obtained by giving a better extractor for (q, t, γ) non-oblivious bit...

an experimental study has been conducted on the hydrodynamics of a stage mixer-settler to obtain an appropriate design. in this paper several tests was performed to investigate full factorial design of experiments. since each test was repeated seven times, the repeatability of the test was confirmed (p=1 bar and t=25 °c). sauter diameter was determined by photographing both the mixer and settle...

an experimental study has been made of the hydrodynamics of a stage mixer-settler to obtain appropriate design information. in this paper several tests were done according to full factorial design of experiments with high reliability, since each test recurs seven times and the results of  them are very close to each other(p=1bar and t=25 °c). sauter diameter in each test is determined with phot...

The NucliSens Extractor is an automated nucleic acid isolation system based on guanidinium thiocyanate (GuSCN)-silica extraction technology. The system has been validated for the isolation of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) RNAs from human samples in combination with nucleic acid sequence-based amplification- and reverse transcription-PCR-based methods. We evaluat...

Using a nuclease-dead Cas9 mutant, we show that Cas9 reproducibly induces chromatin accessibility at previously inaccessible genomic loci. Cas9 chromatin opening is sufficient to enable adjacent binding and transcriptional activation by the settler transcription factor retinoic acid receptor at previously unbound motifs. Thus, we demonstrate a new use for Cas9 in increasing surrounding chromati...
