RISDesigning Rigidly Foldable Horns Using Bricard's Octahedron
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a design method to obtain a family of rigidly foldable structures with one degreeoffreedom (DOF). The mechanism of flatfoldable degreefour cones and mutually compatible cones sharing a boundary is ...
Designing Freeform Origami Tessellations by Generalizing Resch's Patterns
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this research, we study a method to produce families of origami tessellations from given polyhedral surfaces. The resulting tessellated surfaces generalize the patterns proposed by Ron Resch and allow the construction ...
Directional Force Sensation by Asymmetric Oscillation From a Double-Layer Slider-Crank Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By subjecting a small object in a handheld device to periodic translational motion with asymmetric acceleration (accelerated more rapidly in one direction than in the other), the holder typically ...
Scattering of Internal Waves with Frequency Change over Rough Topography
Publisher: American Meteorological Society
Abstract: The frequency change in internal gravity waves upon scattering from a rough topography is investigated analytically. For this, sets of appropriate and tractable governing equations for various parameter regimes are derived ...
A Growth Mechanism for Topographic Internal Waves Generated by an Oscillatory Flow
Publisher: American Meteorological Society
Abstract: On the basis of ray tracing of individual waves generated at various phases of the tidal flow, an amplification mechanism is presented for a new class of topographically generated internal waves identified by Nakamura et ...
Real-Time Tsunami Prediction by Inversion Method Using Offshore Observed GPS Buoy Data: Nankaido
Publisher: American Society of Civil Engineers
Abstract: In Japan, the probability of a Tokai, Tonankai, and Nankai earthquake occurring in the early 21st century is high. Given this likelihood, estimating the resulting tsunami in real time is desirable. This study details an ...
Geometry and Kinematics of Cylindrical Waterbomb Tessellation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Folded surfaces of origami tessellations have attracted much attention because they often exhibit nontrivial behaviors. It is known that cylindrical folded surfaces of waterbomb tessellation called waterbomb tube can ...
Testing the Multivariate Hüsler–Reiss Model as a Practical Parametric Approach for Multiple River Flood Risk Assessment Using d4PDF Data: A Case Study in Kyushu Island, Japan
Publisher: ASCE
Abstract: Compound flood disaster risks are increasing due to multiple river floods within a single storm event. Many studies targeted dependence structure based on multivariate extreme value theory; however, fewer studies focused ...
Designing and Analyzing Multistable Mechanisms Using Quadrilateral Boundary Rigid Origami
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multistable origami and its snapping behaviors between the folded states have attracted scientists’ and engineers’ attention as the building block for the design of mechanical devices and metamaterials. We propose a novel ...
