In 2015, Driemel, Krivošija, and Sohler introduced the k,ℓ -median clustering problem for polygonal curves under Fréchet distance. Given a set of input curves, asks to find k median at most ℓ vertices each that minimize sum distances over all their closest curve. A major shortcoming algorithm is are restricted lie on real line. this article, we present randomized bicriteria-approximation works ...

A new type of hybrid three-dimensional scaffolds was prepared using poly(ɛ-caprolactone) (PCL) and chitosan-modified montmorillonite by solvent casting and particulate leaching method. The scaffolds were characterized by scanning electron microscopy coupled with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and dynamic mechanical analysis to study the structural and mechanical ...

One of the most commonly used techniques in aerospace engineering is RANS (Reynolds average Navier–Stokes) approach for calculating transonic compressor flow field, where accuracy computation significantly affected by turbulence model used. In this work, we use SA, SST, k-ɛ, and PAFV developed based on side-biased mean fluctuations velocity strain rate tensor to numerically simulate NASA Rotor ...

The primary purpose of the paper is to report a study auto-ignitive and anti-knock properties, firstly neat n-butanol in air, secondly its blends with gasoline-type, Toluene Reference Fuel (TRF). This involved blending ratios 10, 20, 40, 85% by volume TRF. Pressures were range 2–6 MPa, temperatures ranged from 678 916 K. Mathematical modelling detailed chemical kinetics for these conditions, us...

In this paper, we attempt to refine our understanding of the relationship between Southern Vowel Shift (SVS) norms and Southern orientation in the U.S. We ask to what degree Southerners from three different states (TN, NC, VA) show evidence of these shifts acoustically. Most crucially, we examine how much the different locales vary in terms of how much they align with traditional Southern featu...

This study concerns differences in the perception of phonemes that have undergone near merger within the past few generations in the Copenhagen speech community. It is hypothesized that this process can lead to a difference in phoneme boundaries across generations. We studied the effect of speaker and listener age on the placement of the phoneme boundary between /ɛ/ and /a/ in Copenhagen Danish...
