A uniform, flexible and frictionless chain falling link by link from a heap by the edge of a table falls with an acceleration g/3 if the motion is nonconservative, but g/2 if the motion is conservative, g being the acceleration due to gravity. Unable to construct such a falling chain, we use instead higherdimensional versions of it. A home camcorder is used to measure the fall of a threedimensi...
This manual describes a z-Tree (Fischbacher, 2007) implementation of the paper-based Social Vaule Orientation (SVO) Slider Measure by Murphy et al. (2011). Using the paperbased version instead of the slider-based version (as implemented on the SVO-Website) avoids server-traffic related delays we experienced in the latter implementation. JEL-Classification: C91, D03, D64
Contact between a slider and bit patterned media (BPM) is investigated using finite element analysis. The effect of contact conditions and material properties at the interface between slider and disk on plastic deformation and temperature is studied. In addition, the planarization of bit pattern media on temperature and plastic deformation is investigated for different filler materials. It is f...
An incompressible Newtonian fluid is forced through the porous of a circular slider which is moving laterally on a horizontal plan. In this paper, we introduce and apply the one step Optimal HomotopyAnalysisMethod one step OHAM to the problem of the circular porous slider where a fluid is injected through the porous bottom. The effects of mass injection and lateral velocity on the heat generate...
This paper presents the successful demonstration of a large-stroke, high-precision inchworm microactuator. The actuator is capable of zero-power latching, or forcibly maintaining its position by using pre-stressed spring load. The actuator is driven by a combination of a PZT-stack actuator unit for slider thrust and electrostatic comb-drive units for slider grip. Incremental step size is precis...
A slider-slab sliding model for hard-to-soft and soft-to-soft sliding systems with abrasive and non-abrasive wear conditions is used to investigate atomic-scale friction. The molecular dynamics simulation uses the Morse potential to calculate interatomic forces between atoms. Separation distance between the slider and the slab is changed to simulate repulsive and attractive interactive force fi...
A Laman mechanism is a flexible planar bar-and-joint framework with m ≤ 2n− 3 edges and exactly k = 2n−m internal degrees of freedom. The mechanism can be completely immobilized by constraining the coordinates of some of the vertices to lie on fixed straight lines. The Slider Pinning problems asks for the minimum set of sliders that will pin a given mechanism. A particular degenerate case is to...
User interfaces involving explicit control of numeric values in immersive virtual environments have not been well studied. In the context of designing three-dimensional interaction techniques for the creation of multiple objects, called cloning, we have developed and tested a dynamic slider interface (D-Slider) and a virtual numeric keypad (VKey). Our cloning interface requires precise number i...
