We consider a smooth, spanwise-uniform forward-facing step defined by a Gauss error function of height 4 %–30 % and four times the width of the local boundary layer thickness δ99. The boundary layer flow over a smooth forward-facing stepped plate is studied with particular emphasis on stabilisation and destabilisation of the twodimensional Tollmien–Schlichting (TS) waves and subsequently on thr...
Background and purpose: Airway stenosis is one the most dangerous diseases. Anethum graveolens L.(Dill) has anti-spastic effect on smooth muscle. The aim of this study was to investigate the effect of the hydroalcoholic extract of this plant on male rat tracheal smooth muscle contractile activity. Materials and methods: In this experimental study, tracheas of healthy rats were dissected. We in...
The dark channel prior (DCP) technique is an effective method to enhance hazy images. Dark channel is an image with the same size as the hazy image which represents the haze severity in different places of the image. The DCP method suffers from two problems: it is incapable for removing haze from smooth regions, causing blocking effects on these areas; it cannot properly reduce a haze with a no...
