In this paper, the dynamic analysis of the composite sandwich truncated conical shells (STCS) with various boundary conditions subjected to the low velocity impact was studied analytically, based on the higher order sandwich panel theory. The impact was assumed to occur normally over the top face-sheet, and the contact force history was predicted using two solution models of the motion which we...

Abstract A universal conical spreader for uniform distribution of granular fertilizers and seeds grain crops, grasses is proposed. The developed designed subsurface application above-mentioned materials using seed drills can be used as a passive distributor in wide variety applications. methods theoretical mechanics descriptive geometry, particularly the method replacement projection plane have...

Abstract This article outlines the development of an elastically foldable, bistable diaphragm geometry that enables increase in compression volume compressors compared to use flat diaphragms. Using a Finite Element Model (FEM) ABAQUS/Standard, several membrane geometries (truncated cone, and dome) were calculated analyzed with regard their elastic deformation. Selected produced using Single Poi...

The traditional continuous wavelet transform is plagued by the cone-ofinfluence, ie wavelets which extend past either end of a finite timeseries return transform coefficients which tend to decrease as more of the wavelet is truncated. These coefficients may be corrected simply by rescaling the remaining wavelet. The corrected wavelet transform displays no cone-of-influence and maintains reconst...

The long object problem is practically important and theoretically challenging. To solve the long object problem, spiral cone-beam CT was first proposed in 1991, and has been extensively studied since then. As a main feature of the next generation medical CT, spiral cone-beam CT has been greatly improved over the past several years, especially in terms of exact image reconstruction methods. Now...

Cytoskeleton dynamics are critical phenomena that underpin many fundamental cellular processes. Collapsin response mediator proteins (CRMPs) are highly expressed in the developing nervous system, mediating growth cone guidance, neuronal polarity, and axonal elongation. However, whether and how CRMPs associate with microtubules and actin coordinated cytoskeletal dynamics remain unknown. In this ...

This research conducts experimental studies on supercavitation bubble development and characteristics within free-surface water the role of cavitator, comparing results to those similar experiments carried in a duct flow. Tests have been conducted cylindrical bodies (47 mm diameter) moving underwater at different velocities 10-m-diameter circular pool about 50 cm level. A comparison has made fo...
