This article presents a new observer design approach for linear time invariant multivariable systems subject to unknown inputs. The is based on transformation the so-called special coordinate basis (SCB). form reveals important system properties like invertability or finite and infinite zero structure. Depending system's strong observability properties, SCB allows straightforward input utilizin...

This work investigates fracture characteristics of a marble semi-circular bend (SCB) specimen with pre-defined crack under compressive loading condition. It aims at evaluating how the toughness can be affected by and span length variation. Numerically, model is solved using meshless methods, extended to linear elastic mechanics (LEFM), resorting radial point interpolation method (RPIM) its natu...

Biogenic volatile organic compounds (BVOCs) impact atmospheric oxidation capacity and regional air quality through various biogeochemistry processes. Accurate estimation of BVOC emissions is crucial for modeling the fate transport pollutants in chemical models. Previous characterizes spatial variability BVOCs while estimated show large uncertainties, impacts on ozone (O 3 ) are not well underst...

Fifteen cases were selected from May to September 2010 2021 study the moisture transport of nocturnal rainstorms in mountainous areas around western Sichuan Basin (western SCB). Nocturnal mainly occur along mountains southwestern SCB, 22 04 LST, peaking at 00 LST. The four following paths (proportions) obtained using Hybrid Single Particle Lagrangian Integrated Trajectory model (HYSPLIT): local...
