This paper describes the lightpath planning and monitoring software suite developed specifically for managing lightpaths in the hybrid SURFnet6 network and the NetherLight optical exchange point. Lightpaths are high bandwidth circuits with deterministic quality of service characteristics. These lightpaths are used by researchers in demanding network projects. The concept of the high bandwidth l...

OBJECTIVES We sought to examine whether contrast-enhanced multidetector row computed tomography (MDCT) allows prediction of X-ray angiographic planes for the root angiogram in the context of transcatheter aortic valve implantation. BACKGROUND Understanding of aortic root orientation relative to the body axis is critical for precise positioning of the stent/valve during transcatheter aortic va...

Scenario planning is one of the most widespread futures methodologies in use. A generic aim of scenario planning, as with many Futures Studies methodologies, is to broaden and deepen perceptual filters so as to find new and relevant meaning in 'weak signals from the future.' Integral Studies is an emerging field of meta-theory that attempts to meaningfully relate as many disciplines of human kn...

Low volume production associated with space systems manufacturing is inherently expensive, time-consuming, and risk-laden. At the root of this problem is an inability to adequately predict, monitor, and control the product development and sustainment process. This paper describes the ASSIST system, an intelligent knowledge management system designed to address inefficient information management...

Prospection, the act of predicting the consequences of many possible futures, is intrinsic to human planning and action, and may even be at the root of consciousness. Surprisingly, this idea has been explored comparatively little in robotics. In this work, we propose a neural network architecture and associated planning algorithm that (1) learns a representation of the world useful for generati...

This paper presents a generalization of the classic A* algorithm to the domain of sampling-based motion-planning. The root assumptions of the A* algorithm are examined and reformulated in a manner that enables a direct use of the search strategy as the driving force behind the generation of new samples in a motion-graph. Formal analysis is presented to show probabilistic completeness and conver...

INTRODUCTION Orthodontists assess mesiodistal root angulations before, during, and after orthodontic treatment as an aid in establishing proper root position. Panoramic imaging has been useful for this purpose and is a valuable screening tool in diagnosis and planning treatment of orthodontic patients. Cone-beam computed tomography (CBCT) for imaging of the craniofacial complex creates the oppo...
