The hierarchical multiscale analysis normally utilizes a microscopic representative volume element (RVE) model to capture path/history-dependent macroscopic responses instead of using phenomenological constitutive models. However, for problems involving large deformation, the current RVE used in geomechanics may lose properties due progressive distortion box, unless proper reinitialization is a...

The nighttime ionospheric response to a geomagnetic storm that occurred on 23–29 September 2020 is investigated over the South American, Atlantic, and West African longitude sectors using NASA's Global-scale Observations of Limb Disk measurements. On 27 solar wind conditions were favorable for prompt penetration electric fields influence equatorial ionosphere extended longitudes. ionization ano...

Abstract The Energy Performance of Buildings (EPB) regulations aim to reduce primary energy use and carbon dioxide emissions buildings, which are the result creating a comfortable healthy indoor environment. In this study, influence climate change on regulatory EPB calculation results is analysed for Flanders region in Belgium. analysis may be used by authorities better define nearly zero build...

For the two types of shield tunneling such as Slurry and EPB shield the stability of tunnel face depends on the prevailing support pressure. The support pressure at the tunnel face has to be applied to a value that gives as well sufficient safety against a collapse of the tunnel face as the against uplifting. The paper aims at a better understanding of the mechanics of face failure for those la...

Abstract The subway tunnels built in some coastal cities often cross the soft and hard alternating strata, which makes shield construction more difficult. single mode cannot meet needs of efficient environmental protection, while dual (TBM-EPB) can better adapt to complex geological conditions alternating, effectively improve tunneling efficiency machine, ensure safety timeliness project constr...

Background: de Quervain’s disease is a commonly encountered debilitating condition mostly treated conservatively. Cadaveric studies have revealed anatomical variations in the first dorsal compartment of wrist; however, causal association between variants and recurrence has not been established. An ultrasonographic assessment wrist was done, to correlate response treatment, different variants. M...

The design, integration, testing and launch of the first Finnish satellite Aalto-1 is briefly presented in this paper. Aalto-1, a three-unit CubeSat, launched into Sun-synchronous polar orbit at an altitude approximately 500 km, operational since June 2017. It carries three experimental payloads: Aalto Spectral Imager(AaSI), Radiation Monitor (RADMON) Electrostatic Plasma Brake (EPB). AaSI hype...
