Stable Prehensile Pushing: In-Hand Manipulation with Alternating Sticking Contacts
, 2018 This paper presents an approach to in-hand manipulation planning that exploits the mechanics of alternating sticking contact. Particularly, we consider the problem of manipulating a grasped object using external pushes for which the pusher sticks to the ...

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Advanced Functional Materials, EarlyView.Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Ecology and Society, 2014 In this study we examine poverty in local fisheries using a social-ecological resilience lens. In assessing why "fishery may rhyme with poverty", Christophe Béné suggests a typology of impoverishment processes, which includes economic exclusion, social ...

Repeatability of push-up and push-down methods in the measure of accommodation amplitude [PDF]
, 2017 La mesura de l’amplitud d’acomodació és una pràctica molt habitual en optometria. La majoria de professionals coincideixen en que els mètodes push-up i push-down són els més utilitzats als exàmens visuals degut al fet que són mètodes ràpids, fàcils i ...

Through Diamond Robust Surface Enhanced Raman Spectroscopy
Advanced Functional Materials, EarlyView.Thin film diamond growth offers a unique opportunity for Surface Enhanced Raman Spectroscopy (SERS); the encapsulation of plasmonic nanostructures within a transparent, chemically stable, and physically robust coating. The diamond acts as both a window and protective layer, enabling illumination of the plasmonic nanostructures through the diamond ...

A Generic Optimization Framework for Mobile Gis Queries
Journal of Algorithms & Computational Technology, 2010 With the increase in the number of non-expert mobile-users, applications have recently been developed to query Geographic Information Systems (GIS) particularly Location Based Services where users ask questions related to their position whether they are ...

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires
Advanced Functional Materials, EarlyView.Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...
