ON THE DESIGN OF PAMINSA1: A NEW CLASS OF PARALLEL MANIPULATORS WITH HIGH-LOAD CARRYING CAPACITY

by Sébastien Briot, Sylvain Guégan, Eric Courteille, Vigen Arakelian, Département Génie, Mécanique Automatique
"... This paper deals with the new results concerning the topologically decoupled parallel manipulators called PAMINSA. The conceptual design of these manipulators, in which the copying properties of pantograph linkage are used, allows obtaining a large payload capability. A newly synthesized fully decou ..."

Event-based prospective memory and executive control of working memory

by Richard L. Marsh, Jason L. Hicks, Richard L. Marsh, Jason L. Hicks, Department Of Psychol - Journal of Experimental Psychology: Learning, Memory, and Cognition , 1998
"... In 5 experiments, the character of concurrent cognitive processing was manipulated during an event-based prospective memory task. High- and low-load conditions that differed only in the difficulty of the concurrent task were tested in each experiment. In Experiments 1 and 2, attention-demanding task ..."
Abstract - Cited by 64 (15 self) - Add to MetaCart
-demanding tasks from the literature on executive control produced decrements in prospective memory. In Experiment 3, attention was divided by different loads of articulatory suppression that did not ultimately lead to decrements in prospective memory. A high-load manipulation of a visuospatial task requiring

Tracking control of nonlinear systems using sliding surfaces with application to robot manipulators

by J. J. Slotine, S. S. Sastry - International Journal of Control , 1983
"... We develop a methodology of feedback control to achieve accurate tracking in a class of non-linear, time-varying systems in the presence of disturbances and parameter variations. The methodology uses in its idealized form piecewise continuous feedback control, resulting in the state trajectory &apos ..."
Abstract - Cited by 157 (1 self) - Add to MetaCart
continuous control laws may be used to approximate the discontinuous control law to obtain robust tracking to within a prescribed accuracy and decrease the extent of high frequency signal. The method is applied to the control of a two-link manipulator handling variable loads in a flexible manufacturing

Research Article Effects of Moderate-Volume, High-Load Lower-Body Resistance Training on Strength and Function in Persons with Parkinson’s Disease: A Pilot Study

by Brian K. Schilling, Ronald F. Pfeiffer, Mark S. Ledoux, Robyn E. Karlage, Richard J. Bloomer, Michael J. Falvo
"... License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Background. Resistance training research has demonstrated positive effects for persons with Parkinson’s disease (PD), but the number of acute training variables that c ..."

questionnaire. Results. There was a significant group-by-time effect for maximum leg press strength relative to body mass, with the training group significantly increasing their maximum relative strength (P <.05). No other significant interactions were noted (P>.05). Conclusions. Moderate volume, high-load

Efficient, Transparent and Comprehensive Runtime Code Manipulation

by Derek L. Bruening , 2004
"... This thesis addresses the challenges of building a software system for general-purpose runtime code manipulation. Modern applications, with dynamically-loaded modules and dynamicallygenerated code, are assembled at runtime. While it was once feasible at compile time to observe and manipulate every i ..."

Failure Analysis of Parallel Manipulators . . .

by Li Huang , 1999
"... Parallel manipulators have the advantages of having low inertia high ngidity and high load capacity. These advantages are usefuI where high speed, payload and accuracy are required. With the expansion of the appiications oFparaiIe1 manipulators to areas such as space and medicai environrnents, the ..."

Persistence of net heterotrophy in lakes during nutrient addition and food web manipulations

by Jonathan J. Cole, Michael L. Pace, Stephen R. Carpenter, James F. Kitchell - Limnol. Oceanogr , 2000
"... Net ecosystem production (NEP) is the difference between gross primary production (GPP) and community respiration (R). We estimated in situ NEP using three independent approaches (net CO2 gas flux, net O2 gas flux, and continuous diel O2 measurements) over a 4–7 yr period in a series of small lakes ..."
Abstract - Cited by 37 (5 self) - Add to MetaCart
in which food webs were manipulated and nutrient loadings were experimentally varied. In the absence of manipulation, these lakes were net heterotrophic according to all three approaches. NEP (NEP 5 GPP-R) was consistently negative and averaged 235.5 6 3.7 (standard error) mmol C m22 d21. Nutrient

Altering Java Semantics via Bytecode Manipulation

by Eric Tanter, Marc Segura-devillechaise, Jacques Noye, Jose Piquer , 2002
"... Altering the semantics of programs has become of major interest. This is due to the necessity of adapting existing software, for instance to achieve interoperability between o#-the-shelf components. A system allowing such alterations should operate at the bytecode level in order to preserve portabil ..."

portability and to be useful for pieces of software whose source code is not available. Furthermore, working at the bytecode level should be done while keeping high-level abstractions so that it can be useful to a wide audience. In this paper, we present Jinline, a tool that operates at load time through

Learning object models for whole body manipulation

by Mike Stilman, Koichi Nishiwaki, Satoshi Kagami - In Int. Conf. on Humanoid Robotics (Humanoids’07 , 2007
"... Abstract — We present a successful implementation of rigid grasp manipulation for large objects moved along specified trajectories by a humanoid robot. HRP-2 manipulates tables on casters with a range of loads up to its own mass. The robot maintains dynamic balance by controlling its center of gravi ..."

Single Atom Manipulation in a Microscopic Dipole Trap

by Georges Reymond, Nicolas Schlosser
"... We describe the operation of a very small optical dipole trap that is designed to store and manipulate individual atoms. Due to the very small dipole trap volume, a “collisional blockade ” mechanism locks the average number of trapped atoms on the value 0.5 over a large range of loading rates. We de ..."
