Abstract The excellent deformation performance of structure is the material basis intelligent morphing aircraft. In this study, a zero Poisson’s ratio honeycomb consisting sinusoidal corrugated walls applied to in-plane mechanical properties are deduced theoretically based on assumption small strain. According application requirements tensile and shear deformation, an optimization model establi...

The 'colour-shading effect' describes the phenomenon whereby a chromatic pattern influences perceived shape-from-shading in a luminance pattern. Specifically, the depth corrugations perceived in sinusoidal luminance gratings can be enhanced by spatially non-aligned, and suppressed by spatially aligned sinusoidal chromatic gratings. Here we examine whether colour contrast can influence perceived...

Pursuit eye movements alter retinal motion cues to depth. For instance, the sinusoidal retinal velocity profile produced by a translating, corrugated surface resembles a sinusoidal shear during pursuit. One way to recover the correct spatial phase of the corrugation's profile (i.e. which part is near and which part is far) is to combine estimates of shear with extra-retinal estimates of transla...

Vortex dynamics is an important research subject for geophysics, astrophysics, engineering, and plasma physics. Regarding vortex interactions, only limited problems, such as point have been studied. Here, the nonlinear interaction of two non-uniform sheets with density stratification investigated using sheet model. These appear, example, in Richtmyer–Meshkov instability that occurs when a shock...

Purpose. The main purpose of this work is to substantiate the design features sandwich panels for manufacture container walls size 1SS. Methodology. To ensure strength walls, it proposed use as their components. This involves a panel from two metal sheets, between which material with energy-absorbing properties placed. solution helps improve by reducing its load. determine thickness sheet, corr...

The article describes the features of work beams with a thin transverse corrugated web plate. Exponential fractional regression is presented, which allows one to estimate relative height plate sections working together flanges, obtained by authors based on an analysis numerical experiments. Based work, method proposed for describing stress state arbitrary cross-section I-beam (the profile corru...

The effect of external-recycle operations on the thermal performance double-pass cross-corrugated solar air heaters (SAH) under different operating conditions was investigated experimentally and theoretically. Additionally, simultaneous ordinary equations were solved analytically for each proposed configuration. Four recycling types are introduced improving with external recycle processes, whic...

Remotely sensed images with a pixel size of about 1 m can nowadays be acquired by airborne scanners and in the near future also by high resolution satellites. With such a high spatial resolution, remotely sensed data of urban areas can resolve structures like a roof into the different surface segments with different inclinations, e.g. in the case of a gabled roof. We have measured the BRDF (Bid...
