11 Abstract In this paper, we present the results of an exploratory study into the relationship 12 between student self-efficacy and guidance use in a Multi-User Virtual Environment 13 (MUVE) science curriculum project. We describe findings from a sample of middle school 14 science students on the combined impact on learning of student self-efficacy in scientific 15 inquiry and use of individua...

A new technique named as model predictive spread acceleration guidance (MPSAG) is proposed in this paper. It combines nonlinear model predictive control and spread acceleration guidance philosophies. This technique is then used to design a nonlinear suboptimal guidance law for a constant speed missile against stationary target with impact angle constraint. MPSAG technique can be applied to a cl...

Blindfolded participants were guided along routes from two display modes: spatial language ("left," "right," or "straight") or spatialized audio (where the perceived sound location indicates the target direction). Half of the route guidance trials were run concurrently with a secondary vibrotactile N-back task. To assess cognitive map development, subjects performed a homing task from the route...

Direct methods for trajectory optimization are traditionally based on a priori temporal discretization and collocation methods. In this work, the problem of node distribution is formulated as an optimization problem, which is to be included in the underlying NLP. The benefits of utilizing the suggested method for on-line trajectory optimization, are illustrated by a missile guidance example.

Abstract The design of guidance law for smart missile based on implicit dynamic-inverse direct mode configuration is described in this paper. theory and algorithm are applied to the law. pitching acceleration yaw designed pitch channel by using augmented proportional respectively. attacking time parameter attack error equation introduced as constraint criteria dynamic-inverse. According singula...

Differential Game Based Guidance Law for High Angle of Attack Missiles By P. K. Menon and G.B. Chatterji Optimal Synthesis 450 San Antonio Road, Suite 53 Palo Alto, CA 94303 Abstract A nonlinear differential game theoretic intercept guidance law for short range missiles is derived. Differential geometric transformations are used to convert the nonlinear missile and the target models into a conv...

We construct and apply a stochastic Gaussian Process (GP) model of flight trajectory generation for pigeons trained to home from specific release sites. The model shows increasing predictive power as the birds become familiar with the sites, mirroring the animal’s learning process. We show how the increasing similarity between successive flight trajectories can be used to infer, with increasing...

We applied two-photon polymerization to fabricate 3D synthetic niches arranged in complex patterns to study the effect of mechano-topological parameters on morphology, renewal and differentiation of rat mesenchymal stromal cells. Niches were formed in a photoresist with low auto-fluorescence, which enabled the clear visualization of the fluorescence emission of the markers used for biological d...

In this work we study how people navigate the information network of Wikipedia and investigate (i) free-form navigation by studying all clicks within the English Wikipedia over an entire month and (ii) goal-directed Wikipedia navigation by analyzing wikigames, where users are challenged to retrieve articles by following links. To study how the organization of Wikipedia articles in terms of layo...
