Introduction While the vast majority of clinical MRI sequences utilize Cartesian sampling strategies, in a growing number of applications nonCartesian schemes are being employed for a variety of technical reasons. For example, our own motivation is diffusion tensor imaging (DTI) wherein we use spiral trajectories [1], in part because they facilitate efficient self-navigation schemes for artifac...

tm is a program designed to test systems by simulating over-exaggerated use. The program can be used to check the accuracy of shared resources of a system or determine if a system will fail under intensive use. The simulation of users is done by threads running scripts. The configuration of tm and a description of the scripting language is included. A real test using tm is described and the res...

The sheer complexity of Web applications and inadequate approaches to analyze, design or update such projects generate incorrect environments, which are the source of potential risks. Poor applications reflect low availability, maintenance difficult and questionable efficiency in the services they provide. At present the quality assurances schemes still performed manually. A group of evaluators...

An information processing investigation was performed to quantify the Chevreul pendulum effect: the tendency of a small pendulum, when suspended from the hand and imaginatively concentrated on, to oscillate seemingly of its own accord. Using a time exposure photographic measurement technique, electronically automated visual and auditory imaginal prompts were presented to the subject during imag...

Backstepping control technique is a Lyapunov based nonlinear robust technique which is applicable to only strict feedback system. Backstepping technique has been applied on linear inverted pendulum which is under actuated system. Inverted pendulum is swung from its pendant position and stabilized at its upright position. Swing up is achieved by nonlinear backstepping controller but the linear i...

The rotary inverted pendulum, also named Furuta Pendulum, has been studied extensively for control performance evaluation in under-actuated mechanisms. The H∞ control invoking Linear Matrix Inequality (H∞-LMI) has been also wide employed for linear control design. This paper deals with the feasibility ofH∞-LMI technique to stabilize the rotary inverted pendulum around its unstable equilibrium p...

X–Z inverted pendulum is a new kind of inverted pendulum and it can move with the combination of the vertical and horizontal forces. In this paper, the control problem of X-Z inverted pendulum with system uncertainties is addressed, and a pair of decoupled adaptive fuzzy sliding mode control method is proposed. The fuzzy logic system is employed to approximate the system uncertainties as well a...

This study presents an energy level stabilization algorithm for the pendulum on a cart system with restricted cart track length. The objective is to bring the pendulum to its unstable equilibrium. To do so the energy level of the pendulum is increased or decreased by accelerating the cart in the appropriate direction while keeping within imposed limit positions. To achieve, the equation of moti...

The purpose of this paper is to present the design and program implementation of a general procedure which yields the mathematical model for a classical or rotary inverted pendulum system with an arbitrary number of pendulum links. Lagrange equations of the second kind with an integrated Rayleigh dissipation function are employed in model design, and the energetic balance relations, derived for...

This study tested the generalizability of the consistency effect to real-world settings. The consistency effect refers to the finding that items inconsistent with expectations are better recalled and recognized than items consistent with expectations. In two experiments, subjects walked into a graduate student's office or a preschool classroom. Half of the items in each setting were consistent ...
