An extensive experimental investigation to study the flow structure over the wing of a fighter type configuration model has been conducted. The model used for this study was similar to the High Alpha Research Vehicle (HARV) that has been used in various European research centers for studying its force and moment characteristics. Tests were conducted at two subsonic speeds and at low to moderate...

In this work we study the performance of elevation estimators and lower bounds on the estimation error variance for a low angle target in a smooth sea scenario using an array antenna. The article is structured around some key assumptions on multipath knowledge, signal parameterization and noise covariance, giving the reader a framework in which Maximum-Likelihood estimators exploiting di erent ...

1550-7998=20 We determine the weak mixing angle in the MS scheme, sin
̂W , at energy scales relevant for present and future low-energy electroweak measurements. We relate the renormalization group evolution of sin
̂W to the corresponding evolution of ̂ and include higher-order terms in s and that had not been treated in previous analyses. We also update the analysis of nonperturbative, hadronic c...

11 The growth of megacusps as shoreline instabilities is investigated by ex-12 amining the coupling between wave transformation in the shoaling zone, long-13 shore transport in the surf zone, cross-shore transport, and morphological 14 evolution. This coupling is known to drive a potential positive feedback in 15 case of very oblique wave incidence, leading to an unstable shoreline and the 16 c...

In the present study, the synthesis of poly(1,1-dimethylsilacyclobutane) (PDMSB) by anionic ring opening polymerization (ROP) is reinvestigated, leading to narrowly distributed molar masses (polydispersities 1.04–1.15) in the range of 2.3 to 60 kg mol. Investigations of thermal behavior for low molar mass PDMSB revealed an untypical multiple peaks melting phenomenon, which at first glance, seem...

Different zinc oxide (ZnO) nanostructured thin films were grown on glass substrates at low temperatures by combining successive ionic layer adsorption and reaction (SILAR) method and chemical bath deposition (CBD). Morphologies and structures of the samples were investigated by X-ray diffraction (XRD), energy-dispersive x-ray spectroscopy (EDX) and scanning electron microscopy (SEM). The reacti...

A simultaneous low-temperature X-ray powder-diffractometric (XRD)-DSC technique was applied to the solid state and melting process of frozen aqueous solutions of 2-propanol. 1H NMR spectra were also obtained at low temperatures. The chemical shifts of the CH3 proton and the CH proton can be classified into four temperature regions: higher than -20 degrees C, around -20 degrees C, -50 to -20 deg...

The present work was focused on the synthesis and characterization of hydroxyapatite doped with low concentrations of zinc (Zn:HAp) (0.01 < xZn < 0.05). The incorporation of low concentrations of Zn2+ ions in the hydroxyapatite (HAp) structure was achieved by co-precipitation method. The physico-chemical properties of the samples were characterized by X-ray Diffraction (XRD), Fourier Transform ...

X-ray powder diffraction (XRD) is an essential component of research into use of organometallic precursors as a route to low temperature (<500 “C) synthesis of bulk compound semiconductors. This paper illustrates the use of XRD to study solid solution behavior in the systems SnS-SnSe and PbS-CdS. XRD characterization demonstrated that phase pure intermediate members of the Sn(S,Se) solid soluti...
