Due to climate change, typhoons, especially extreme are becoming more intense and causing ascending financial losses. A majority of previous studies on typhoon economic losses over a period time considered all types rather than the typhoons. This study focuses risk management typhoons by establishing compensation mechanism typhoon-specific insurance product. The annual maximum is first modelled generalized value distribution (GEV) under Extreme Value Theory (EVT). prediction unexpected then...

This study is set against the backdrop of experience economy, focusing on offline clothing consumption scenarios Generation Z (born between 1996 and 2010). It explores impact mechanism multi-dimensional experiences in physical stores arousal positive emotions. Through a questionnaire survey, 270 valid samples were collected, structural equation modeling was employed for analysis. The findings reveal that sensory (visual tactile stimuli), Feeling (staff service theme activities), interactive...

Abstract An ideal static mixer can achieve efficient mixing at low pressure drops. Owing to the excellent performance of tridimensional rotational flow sieve tray (TRST) in a gas–liquid two‐phase system, TRST structure was modified into rotational–perforated (RPSM) enhance multicomponent liquid systems. The energy consumption characteristics RPSM were experimentally studied based on Reynolds numbers range 986–7892, gap L = 0–80 mm, and relative angle γ 0–45°. effects element installation...

The current study investigated the combinatorial effect of cyclic strain and electrical stimulation on neural differentiation potential rat bone marrow-derived mesenchymal stem cells (BMSCs) under epidermal growth factor (EGF) fibroblast 2 (FGF2) inductions in vitro . We developed a prototype device which can provide signal synchronously. Using this system, we demonstrated that co-stimulation promote BMCSs into with more branches longer neurites than or alone. Strain also induce higher...

Abstract The flow characteristics of the blade unit a tridimensional rotational sieve tray were investigated. First, patterns are defined under different liquid arrangement methods. They bilateral film flow, continuous perforated and dispersion‐mixing in overflow distribution, jet mixed spray distribution. Second, time frequency domain analysis differential pressure pulsation signal is carried out, main frequencies range 2.0−5.5 Hz. influence perforation mixing intensity on pattern...

As an emerging business model, live broadcast e-commerce is growing rapidly in China recent years and prompts the emergence of network anchors, attracting customers to buy a variety goods their broadcasts. In this paper, we take Li Jiaqi, one most popular streaming anchors as example, collect transcribe his speech data broadcasts build speech-text corpus, then conduct corpus-based analysis on linguistic characteristics from aspects phonetic, usage various language units, rhetoric ways, by...

To address the effect of a ship’s rolling on fluidization quality fluidized beds, in this study, simulation bed with longitudinal internal members added (R-FBLIM) was carried out and compared that without (R-FBWIM). The transient motion, as well behavioral characteristics bubbles within R-FBLIM, analyzed; variation patterns number bubbles, equivalent diameter were for different apparent gas velocities, oscillation periods, amplitudes; mechanism action investigated. results show structural...

Preparation of high-performance thermosetting resins via bio-based resources is important for the development a sustainable world. In this work, we proposed introduction cyanide structure groups into molecular epoxy to give them excellent heat resistance. A eugenol-based epoxy-phthalonitrile (EEPN) resin was synthesized by two-step process using renewable resource eugenol, and series EEPN/Epoxide (E51) blend with different EEPN contents were prepared. The monomer characterized confirmed...

In an axial granular bed filter (GBF), a new mesoscale simulation approach is obtained by combining the macroscopic calculation models, i.e., equations of total pressure drop and dust-removal efficiency into porous media model source term conservation equations. After grid-dependent tests experimental validation, effects different conditions, height L, superficial gas velocity ug, dust diameter dp, concentration cp, dg, initial voidage ε0, filtration time t, on are investigated. The results...

When transplanting the gas–solid fluidized bed technology to offshore floating platform, flow characteristics in will be affected by rolling of platform. In this paper, field, especially dynamic variation particles, a two-dimensional bed, is investigated using numerical simulation method. The results show that when an inclined position, gas/particle phases gather upper/lower wall region bed. During process behavior periodic change state near region, forming overall particle internal...

The gas flow pattern in the radial bed is simulated by porous and transport models combined with a 6-lump kinetic reaction model (C4 hydrocarbon catalytic pyrolysis), which are verified published experimental results. Aside from simulation method, axial dispersion behavior well explained introducing "common pressure pool" (CPP) "constant drop lines" (CPDL) methods. most severe occurs at turning point of (r – r1)/(r2 r1) = 0.62. However, can still be roughly seen as plug whole for small...
