TL;DR: This paper provides a non-greedy centralized solution to the problem of controlling mobile sensing systems to improve the accuracy and efficiency of gathering information autonomously, and decentralizes the control task to obtain linear complexity in the number of sensors and provide suboptimality guarantees.
Abstract: This paper addresses the problem of controlling mobile sensing systems to improve the accuracy and efficiency of gathering information autonomously. It applies to scenarios such as environmental monitoring, search and rescue, surveillance and reconnaissance, and simultaneous localization and mapping (SLAM). A multi-sensor active information acquisition problem, capturing the common characteristics of these scenarios, is formulated. The goal is to design sensor control policies which minimize the entropy of the estimation task, conditioned on the future measurements. First, we provide a non-greedy centralized solution, which is computationally fast, since it exploits linearized sensing models, and memory efficient, since it exploits sparsity in the environment model. Next, we decentralize the control task to obtain linear complexity in the number of sensors and provide suboptimality guarantees. Finally, our algorithms are applied to the multi-robot active SLAM problem to enable a decentralized nonmyopic solution that exploits sparsity in the planning process.

TL;DR: The results show that in pure compression, the external axial force is transmitted primarily by the intervertebral disc, and the facet joints carry only a small percentage of the force, whereas in small flexion they carry none.

TL;DR: In this paper, a generalization of geometrically linear shear deformation theory for multilayered anisotropic shells of general shape is presented, which includes the effects of shear deformations and rotary inertia as well as initial curvature.

TL;DR: There is potential for improvement and optimization in the seizure prediction framework, and new databases, higher sampling frequencies, adequate preprocessing, electrode selection, and machine-learning considerations are all elements of the prediction scheme that should be assessed to achieve more realistic, better-than-chance performances.

TL;DR: For all inclinations elbow support reduced arm fatigue, and the inclination of 30° got the highest preference ratings, however, 90° was the poorest inclinations with respect to both fatigue and precision.
Abstract: The effect of touchscreen inclination and elbow support on arm fatigue was studied in a factorial design. Inclinations were 0°, 22.5°, 30° 45°, 60° and 90° from horizontal. The subjects could or could not rest the elbow on the desk. Results indicated that an inclination of 22.5° was least fatiguing. The inclination of 30° got the highest preference ratings, however, 90° was the poorest inclinations with respect to both fatigue and precision. For all inclinations elbow support reduced arm fatigue.
