A stereo vision based vehicle/obstacle detection system has been proposed that generates alarms when vehicles/obstacles are detected in vicinity of near/mid region. Numerous techniques have been applied to detect vehicles/obstacles using a forward facing monocular camera mounted inside a vehicle. This paper presents a methodology for vehicle/obstacle detection using high resolution stereo camer...

On-Line Sub-Optimal Obstacle Avoidance Zvi Shiller Mechanical and Aerospace Engineering University of California Los Angeles, CA 90095 Abstract This paper presents an on-line planner for sub-optimal obstacle avoidance. It generates near-shortest paths incrementally by avoiding obstacles optimally one at a time. In known environments, obstacles are avoided in an order determined by a global crit...

We introduce and analyze backscatter data for a three dimensional obstacle problem in electrostatics. In particular, we investigate the asymptotic behavior of these data as, (i), the measurement point goes to infinity, and (ii), the obstacles shrink to individual points. We also provide numerical simulations of these data.

Effective diabetes care requires a partnership between prepared, proactive practice teams and informed, activated patients. Diabetes education helps to overcome many of the barriers to effective self-management by enabling people with diabetes to make informed decisions about their day-to-day self-care. Both psychosocial and health outcomes have been improved through a variety of training progr...

Given a set of obstacles and two distinguished points in the plane the problem of nding a collision free path subject to a certain optimization function is a fundamental problem that arises in many elds, such as motion planning in robotics, wire routing in VLSI and logistics in operations research. In this survey we emphasize its applications to VLSI design and limit ourselves to the rectilinea...

Lacey's high school needed her talent and skills. Located in an urban, working-class community, the school was struggling to serve all students well and had failed to make Adequate Yearly Progress for two years running. As a social studies teacher, Lacey had developed considerable skill in teaching with a project-based format during her four years in the classroom, and her students were making ...

Acoustic scattering problems are considered when the material parameters (density and speed of sound) are functions of position within a bounded region. An integro-differential equation for the pressure in this region is obtained. It is proved that solving this equation is equivalent to solving the scattering problem. Problems of this kind are often solved by regarding the effects of the inhomo...

Laparoscopic radiofrequency ablation of uterine leiomyomas with a new Federal Drug Administration (FDA)-approved device, a device that delivers radiofrequency energy, is a novel procedure that aims to meet patient and physician demand for effective, minimally invasive leiomyoma treatment. However, as a new procedure, the durability of symptom relief, the safety in widespread use, and ultimately...

Close to 500 persons, including government officials, transit system operators, city planners, car builders, suppliers, and consultants, came to Boston Aug. 28-31 for a "National Conference on Light Rail Transit." Although the size of the crowd was evidence of light rail's growing popularity (RA, Aug. 8, p. 36), the conference also heard warnings about trends that could hamper the growth of lig...
