We develop a geometric framework for the stability analysis of multifingered grasps and propose a measure of grasp stability for arbitrary perturbations and loading conditions. The measure requires a choice of metric on the group of rigid body displacements. We show that although the stability of a grasp itself does not depend on the choice of metric, comparison of the stability of different gr...

Cetuximab (Cetux)/Bevacizumab (Bev) treatments have shown considerably survival benefits for patients with metastatic colorectal cancer (mCRC) in the last decade. But they are costly. Currently, no data is available on the health economic implications of testing for extended RAS wild-type (wt) prior to Cetux/Bev treatments of patients with mCRC. This paper aimed to evaluate the cost-effectivene...

Legislators and the courts have begun to recognize the importance of how electronically stored data should be maintained and secured, and how electronic data should be differentiated from their paper analogs. Examples of some of the sweeping pieces of electronic record management legislation include the Health Insurance Portability and Accountability Act (HIPAA) of 1996, the Gramm-Leach-Bliley ...

A systematic method for dynamic analysis of compliant mechanisms is presented including basic formulations for natural frequencies, modes, dynamic response, and frequency characteristics. Methods for design sensitivity analysis are developed to investigate the effect of various design parameters on the dynamic performance of compliant mechanisms. A micro compliant stroke amplifier mechanism, fo...

In this paper we describe the mechanical design, gait and control for a modular hexapod robot which makes it compliant to terrain while climbing slopes up and down. The robot uses a unique electronically actuated 2DOF universal spine similar to the spine of the Snake and the four legged animals like leopard, tiger etc.By controlling the amount of stiffness of the spine we were able to make the ...

The tax compliance literature indicates that many factors, including, economic, social, psychological and demographic, impact upon the compliance behaviour of taxpayers. This research study investigated the relationship if any, that exists between major tax compliance variables and the attitudes and behaviour of both selected Australian individual taxpayers’ and tax evaders’ towards tax evasion...

Many robotic tasks require compliant motions, but planning such motions poses special challenges not present in collision-free motion planning. One challenge is how to achieve exactness, that is, (DOFs) and, thus, uncertainties (Mason 1982; Whitney 1985). Contact motion occurs on the boundary of configuration space obstacles (C-obstacles) (Lozano-Pérez 1983), but computing C-obstacles remains a...

This paper describes the architecture of the Simulation-based Intelligent Training and Assessment (SITA) system. SITA is a prototype system that integrates HLA compliant simulation with SCORM compliant instruction to provide a more robust and realistic virtual training environment. The SITA architecture is designed to address issues related to SCORMHLA standards interoperability, cross domain e...

A method for the design of controllers of constrained manipulators in the presence of model uncertainties is developed. The controller must carry out fine maneuvers when the manipulator is not constrained, and compliant motion, with or without interaction-force measurement, when the manipulator is constrained. At the same time stability must be preserved if bounded uncertainties are allowed in ...

The output and input coupling characteristics of the compliant parallel mechanism (CPM) bring difficulty in the motion control and challenge its high performance and operational safety. This paper presents a systematic design method for a 2-degrees-of-freedom (DOFs) CPM with excellent decoupling performance. A symmetric kinematic structure can guarantee a CPM with a complete output decoupling c...
