Hybrid vibro-impact (HVI) oscillations is a strongly nonlinear dynamical regime that involves both linear and collisions under periodic, impulsive, or stochastic excitation. This arises in various engineering systems, such as mechanical components tight rigid constraints, seismic-induced sloshing partially-filled liquid storage tanks, more. The adaptive nonlinearity of the HVI oscillator used b...

We conducted two experiments (total N = 81) to investigate the basis for the large-scale horizontal-vertical illusion (HVI), which is typically measured as 15%-20% and has previously been linked to the presence of a ground plane. In a preliminary experiment, vertical rods of similar angular extents that were either large (4.5-7.5 m) and far, or small (0.9-1.5 m) and near, were matched to horizo...

Semantic labeling of Human-Vehicle Interactions (HVI) helps in fusion, characterization, and understanding cohesive patterns that when analyzed and reasoned, they may jointly reveal pertinent threats. Various Persistent Surveillance System (PSS) imagery techniques have been proposed in the past for identifying human interactions with various objects in the environment. Understanding of such int...

in this paper, penetration of high velocity impact of 4340 steel and tungsten carbide projectiles with specific shapes in to ceramic armor that includes 10 mm alumina (95%) is considered analytically and simulated with ls-dyna software. bernoulli equation used to consider the penetration velocity in ceramics, shows that the penetration is better and easier by increasing projectile density. the ...

INTRODUCTION Chronic venous insufficiency (HVI) is manifested by the progressive signs of venous stasis. This disorder is treated by: compressive bandaging, medicaments, sclerotherapy, surgery, etc. AIM Prospective study of the effects of semisynthetic diosmin (clinical signs, quality of life, local biochemical parameters) on patients with HVI to whom no other method of treatment has previous...

in this article, finite element method and ale formulation were used to numerically simulate impact of low-velocity specific projectiles with water surface. for the simulation, ls-dyna finite element code was used. material models which were used to express behavior of air and water included null material model. for the projectile, plastic-kinematics material model was applied. mie-gruneisen eq...

BACKGROUND The hallux valgus interphalangeus (HVI) deformity is described as rare, but improved outcomes in hallux valgus (HV) surgery is associated with its surgical correction via an Akin osteotomy. The hypothesis of this study is that HVI is common and makes a significant contribution to the total valgus deformity of the hallux (TVDH). METHODS 285 pre-operative foot radiographs (193 with H...
