A frontier-based approach for autonomous exploration
- In Proceedings of the IEEE International Symposium on Computational Intelligence, Robotics and Automation
, 1997
"... We introduce a new approach for exploration based on the concept of frontiers, regions on the boundary between open space and unexplored space. By moving to new frontiers, a mobile robot can extend its map into new territory until the entire environment has been explored. We describe a method for de ..."

High-Tc superconductivity in entirely end-bonded multi-walled carbon nanotubes
"... We report that entirely end-bonded multiwalled carbon nanotubes (MWNTs) can exhibit superconductivity with a transition temperature (T c) as high as 12 K, which is approximately 30 times greater than T c reported for ropes of single-walled nanotubes. We find that the emergence of this superconductiv ..."

Pulmonary toxicity of single-walled carbon nanotubes in mice 7 and 90 days after intratracheal instillation.
- Toxicol. Sci.
, 2004
"... Nanomaterials are part of an industrial revolution to develop lightweight but strong materials for a variety of purposes. Singlewall carbon nanotubes are an important member of this class of materials. They structurally resemble rolled-up graphite sheets, usually with one end capped; individually t ..."

this country into the next industrial revolution Carbon nanotubes structurally resemble rolled-up graphite sheets with one end capped. These tiny tubes can have single or multiple walls. Single-wall carbon nanotubes (NTs), unlike graphite or carbon black, possess highly desirable electrical, mechanical
Suboptimal Control of Turbulent Channel Flow for Drag Reduction
- J. Fluid Mech
, 1998
"... this paper is to demonstrate that a wise choice of the cost functional coupled with a variation of the formulation can lead to a more practical control law. We present how to choose a cost functional and how to minimize it to yield simple feedback control laws that require quantities measurable only ..."

only at the wall. One of the laws requires spatial information on the wall pressure over the entire wall and the other requires information, also over the entire wall, on one component of the wall shear stress. We then derive more practical control schemes that only require local wall pressure or local
Wall and Education
"... Arthur Schopenhauer: “Approximately every 30 years, we declare the scientific, literary and artistic spirit of the age bankrupt. In time, the accumulation of errors collapses under the absurdity of its own weight.” RH: “Mesmerized by the Gordon Moore Curve, we in CS slowed down our learning curve. F ..."

. Finally, after 60 years, we are witnessing the spirit from the Mainframe Age collapsing under the von Neumann syndrome.” Because of high energy consumption our computer-based infrastructure may become unaffordable- without reinventing the entire computing discipline, also due to cope with the manycore
A Wall-sized Focus plus Context Display
- In Proceedings of the Fifth Annual IEEE Conference on Pervasive Computing and Communications (PerCom
, 2007
"... In this paper we present a wall-sized focus plus context display, consisting of three back-projected displays and a steerable projector for output. For input tracking we use a commercial SmartBoard with high precision optical tracking and four additional webcams which provide lower precision trackin ..."

tracking on the entire wall. Our approach hence offers two different resolutions in both the output and input direction and thus implements a two-way focus plus context concept with three levels of interactivity. We describe the implementation of such a display and discuss the tracking issues encountered
The Gastrointestinal Wall Layers An Aid in Sonographic Detection of Gastric Wall Lesions and Rectal Wall
"... Recent developments in the understanding of the sonographic appearance of the bowel wall, made possible by improvements in ultrasound technology, have given sonography a unique role to play in the evaluation of gastrointestinal lesions. Changes in wall thickness, alterations of normal structures, an ..."

, and complete obliter-ation of the entire wall structure can be observed. This report reviews the sonographic appearance of the histologic wall structures and shows cases that illustrate how the knowledge of those structures can help the sonographer to evaluate gastrointestinal lesions.

Recovering the Spatial Layout of Cluttered Rooms
"... In this paper, we consider the problem of recovering the spatial layout of indoor scenes from monocular images. The presence of clutter is a major problem for existing singleview 3D reconstruction algorithms, most of which rely on finding the ground-wall boundary. In most rooms, this boundary is par ..."

Inverse Determination of Smelter Wall Erosion Shapes Using a Fourier Series
- Method,” Proceedings of the International Symposium on Inverse Problems in Engineering Mechanics—ISIP ‘03
, 2003
"... An algorithm has been developed for the non-destructive determination of local thickness of the refractory material walls in smelter furnaces. This method uses measurements of temperature and heat flux at a number of points on the outer (fixed) surface of the furnace and assumes that the inner (gues ..."
