The rostral ventrolateral medulla (RVLM) is considered a major center for the regulation of sympathetic and cardiovascular activities. Several clinical studies have indicated a possible causal relationship between neurovascular contact of the left RVLM and essential hypertension, and some investigators have suggested that the left RVLM is more sensitive to pulsatile compression than the right R...
Abstract Local gyrokinetic simulations use a field-aligned domain that twists due to the magnetic shear of background equilibrium. However, if is strong and/or long, twist can become so extreme it fails properly resolve turbulence. In this work, we derive and implement ‘non-twisting flux tube,’ local simulation remains rectangular at all parallel locations. Convergence runtime tests indicate ca...
This study presents a new mechanical tube cladding process named punch plastic deformation pipe cladding (PPDPC) based on local deformation by pressing a punch into the inner layer of the bimetal tube. To investigate the capability of the process, stainless steel tube (as the inner layer) is bonded to a carbon steel pipe (as the outer layer) to fabricate a bimetal pipe. Shear punch tests were u...
Abstract The present research introduces a new configuration of thin-walled nested tube structure as possible energy absorber subjected to lateral compression. nested-tube structures were configured in system comprising four tubes arranged different ways. All the systems quasi-statically compressed direction on universal mechanical tester obtain their absorption characteristics. Two modes defor...
Current research in image compression (wavelets, local trigono-metric bases, JPEG, etc.) centres on adaptive coding of the grey levels of the image. These methods may be described as using band-limiting procedures with a band-limit that depends on the local properties of the image. This paper looks at the non-adaptive use of Discrete Cosine Transforms in blocks, with uniform band-limits over th...
