Application of Scanning Probe Lithography to Graphite Patterning

Journal of Nanoscience and Nanotechnology, 2011
We applied the scanning probe lithographic technique to a graphite patterning in air and analyzed the patterned sample with the lateral force microscopy and Raman spectroscopy. The local electric field generated from a tip caused either etching or oxidization depending on the electric field intensity in air.

An efficient scanning pattern for layered manufacturing processes

Proceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2002
Path generation is an important factor that affects the quality and efficiency of most layered manufacturing processes such as SLS, SLA and FDM. This paper introduces an efficient path generation algorithm. The principle of the algorithm and the implementation are presented. A comparative study is used to analyze the effectiveness of this method.

Effect of scanning speed, scanning pattern, and tip size on the accuracy of intraoral digital scans

The Journal of Prosthetic Dentistry
Currently available intraoral scanning technology makes intraoral scanning quicker and allows the use of smaller scanner tips. However, studies on the influence of scanning speed, tip size, and scanning patterns on scanning accuracy are lacking.The purpose of this in vitro study was to evaluate the effect of scanning speed, scanning pattern, and ...

Lissajous-like scan pattern for a gimballed LIDAR

2014 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2014
In this paper the use of Lissajous-like scan trajectories is studied for a gimballed LIDAR system. In these systems a planar LIDAR sensor is attached to a gimbal, allowing for the collection of 3D range information. Typical gimballed LIDAR systems use raster scan patterns, where the LIDAR is slowly rotated and each line of LIDAR data is collected in ...

Scan encoded test pattern generation for BIST

Proceedings International Test Conference 1997, 2002
This paper presents an improved scan-based BIST scheme which achieves very high fault coverage without any modification of the mission logic, i.e. no test point insertion, no test data to store and very simple BIST hardware which does not depend on the size of the circuit. The approach utilizes scan order and its polarity in scan synthesis, effectively

Random limited-scan to improve random pattern testing of scan circuits

Proceedings of the 38th Design Automation Conference (IEEE Cat. No.01CH37232), 2001
We propose a method of random pattern generation for at-speed testing of circuits with scan. The proposed method uses limited scan operations to achieve complete fault coverage. Under a limited scan operation, the circuit state is shifted by a number of positions which may be smaller than the number of state variables.

Analysis of visual scanning patterns of pistol shooters

Journal of Sports Sciences, 1985
Visual behaviour of pistol shooters of various levels of experience was studied using a video-oculometric technique to record the direction of gaze. A spatio-temporal analysis of the fixation patterns of subjects (five international pistol shooters and five international pentathletes) found that patterns were related to the level of skill.

The Spectrum of Positive Scan Patterns in Parathyroid Scintigraphy

Clinical Nuclear Medicine, 2007
Parathyroid scintigraphy provides the clinician treating primary hyperparathyroidism with valuable information regarding the presence and location of parathyroid adenomas. In dual-phase imaging of the parathyroid glands, a widely employed technique that exploits the radiotracer washout characteristics of parathyroid adenomas, images are typically ...

On Reconnaissance with IPv6: A Pattern-Based Scanning Approach

2015 10th International Conference on Availability, Reliability and Security, 2015
Today's capability of fast Internet-wide scanning allows insights into the Internet ecosystem, but the on-going transition to the new Internet Protocol version 6 (IPv6) makes the approach of probing all possible addresses infeasible, even at current speeds of more than a million probes per second. As a consequence, the exploitation of frequent patterns
