The main aim was to investigate if short-term practice in exploration with a PHANToM can improve performance. A second aim was to find out if some exploration modes are more successful than other modes. Ten participants practiced exploration of nine blocks of 24 virtual objects distributed over

independent of the number of polygons that represent the object. We also propose efficient methods for displaying surface properties of objects such as haptic texture and friction. Our haptic-texturing techniques and friction model can add surface details onto convex or concave 3-D polygonal surfaces

complementary to Fourier preparation by linear field gradients. Thus, by using multiple receiver coils in parallel scan time in Fourier imaging can be considerably reduced. The problem of image reconstruction from sensitivity encoded data is formulated in a general fashion and solved for arbitrary coil

revealed a significant main effect for school motivation, F(3.20, 14000) = 895.27, p < .0001. Newman-Keuls post hoc analyses revealed that the seven motivational subscales were significantly different from one another. The most important forms of motivation for participants in this sample were

from the primary reward to the CS (Pavlovian response transfer). In instrumental conditioning, a reward can become a goal for instrumental behavior if two conditions are met. The goal needs to be represented at the time the behavior is being prepared and executed. This representation should contain a

Modern medical imaging techniques provide an increasing amount of high-dimensional and high-resolution image data that need to be visualized, analyzed, and interpreted for diagnostic and treatment planning purposes. As a consequence, efficient ways of exploring these images are needed. In order

. This functional segregation can reduce the quality of haptic experience, by hiding important details of the dynamic model and reducing the communication bandwidth between the haptic controller and the application. We present a means of closely coordinating a haptic interface with a virtual model, application

the approach developed in Mørck et al. (2000) we find significantly more crosssectional variation in equity returns in markets where short selling is feasible and practiced, controlling for a host of other factors. This evidence is consistent with more efficient price discovery at the individual security level

of incompatible objects to improve recognition performance. Exploration strategies conceived for a single-finger probing device rely on the developed volumetric approximations to guide sensing along directions where uncertainty about the explored object is larger, and can take into account exploration costs. 1

life event, the more likely it is to be recalled; 6 participation in a Seminal work by Ebbinghaus (1894) and many subsequent studies in the survey research literature have shown that recall error tends to increase as a respondent is asked to stretch further back in time. If recall error seriously
