An equivariant, inclination-flip, heteroclinic bifurcation

Nonlinearity, 1996
Summary: We examine a heteroclinic bifurcation occurring in families of equivariant vector fields. Within these families, the flows contain structurally stable heteroclinic cycles. The flow can twist around the cycle to produce what is the equivalent of an `inclination-flip' homoclinic orbit.

Inclination-Flips in the Unfolding of a Singular Heteroclinic Cycle

Chaos, Solitons & Fractals, 2000
We study bifurcations from a singular heteroclinic cycle in ℝ3. This heteroclinic cycle contains a hyperbolic singularity and a saddle-node. At the saddlenode, the linearized vector field has two complex conjugate eigenvalues in addition to an eigenvalue 0.

Biomimetic Flip-and-Flap Strategy of Flying Objects for Perching on Inclined Surfaces

IEEE Robotics and Automation Letters, 2021
Animals can use the maneuver of a flipping body and flapping wings to reduce the normal rebound force of impact during landing, decreasing the adsorption force required by the contact point. This capability aids aerial vehicles with landing not only on vertical surfaces, but also on inclined surfaces.

NONRESONANT BIFURCATIONS OF HETEROCLINIC LOOPS WITH ONE INCLINATION FLIP

International Journal of Bifurcation and Chaos, 2011
Heteroclinic bifurcations in four-dimensional vector fields are investigated by setting up local coordinates near a heteroclinic loop. This heteroclinic loop consists of two principal heteroclinic orbits, but there is one stable foliation that involves an inclination flip.

Vibration characteristics of an inclined flip-flow screen panel in banana flip-flow screens

Journal of Sound and Vibration, 2017
Abstract A banana flip-flow screen is an effective solution for the screening of high-viscosity, high-water and fine materials. As one of the key components, the vibration characteristics of the inclined flip-flow screen panel largely affects the screen performance and the processing capacity.

Codimension 2 reversible heteroclinic bifurcations with inclination flips

Science in China Series A: Mathematics, 2009
The authors consider a four-dimensional system \(\dot{z}=g(z,\mu)\) where \(g\in \mathbb{C}^r\) with \(r\geq 5\) and \(\mu\in {\mathbb R}^l\), \(l>3\) is a small parameter. It is assumed that the system has two fixed points \(p_1(\mu)\) and \(p_2(\mu)\) having in local coordinates the linearizations \[ \dot{x}=\lambda_1^i(\mu)x,\;\; \dot{y}=-\lambda_1 ...

Development of Inclined Conductive Bump for Flip-Chip Interconnection

IEEE Transactions on Components, Packaging and Manufacturing Technology, 2015
In this paper, inclined conductive bumps (ICBs) are proposed as a substitute for the anisotropic conductive film (ACF). The new interconnection method ICBs can provide controlled bump deformation, uniform electrical conductivity, and fine pitch interconnection without short circuit.

Development of inclined conductive bump (ICB) for flip-chip interconnection

2011 IEEE 61st Electronic Components and Technology Conference (ECTC), 2011
The Anisotropic Conductive Film (ACF) has been widely used for interconnection of the display and semiconductor because ACF has various advantages such as the low temperature bonding, low cost and small package size compared with wire bonding. However, as the pitch between the bumps decreases, the short-circuit of the bumps can occur by conductive ...

Fabrication of High‐Voltage Flip Chip Deep Ultraviolet Light‐Emitting Diodes Using an Inclined Sidewalls Structure

physica status solidi (a), 2019
Two types of high‐voltage flip chip deep ultraviolet light emitting diodes (HV‐FC DUV‐LEDs) are constructed with 2 × 2 and 3 × 3 cells, respectively, in which each single cell is fabricated with inclined sidewalls covered by SiO2/Al. The simulation results suggest that the structure with inclined sidewalls is much favorable to extract the transverse ...

Enhancement of InGaN∕GaN Flip-Chip ITO LEDs with Incline Sidewalls Coated with TiO[sub 2]∕SiO[sub 2] Omnidirectional Reflector

Journal of The Electrochemical Society, 2007
The light extraction enhancement of GaN-based flip-chip indium-tin oxide light-emitting diodes (FC ITO LEDs) with an inclined sidewall coated with TiO 2 /SiO 2 omnidirectional reflectors (ODRs) is presented. At a driving current of 350 mA and a chip size of 1 × 1 mm, the light output power and the light extraction enhancement of the FC ITO LEDs coated
