Consider the following setting for an on-line algorithm (introduced in [FS97]) that learns from a set of experts: In trial t the algorithm chooses an expert with probability pi. At the end of the trial a loss vector 1 L ∈ [0, R] for the n experts is received and an expected loss of ∑ i p t iL t i is incurred. A simple algorithm for this setting is the Hedge algorithm which uses the probabilitie...

Performance of trajectory tracking is important for Wheeled Mobile Robots (WMR), which have wide applications in industry, medical treatment, and domestic service, etc. In this paper, comprehensive modeling of a WMR is presented with model parameters estimated via system identification. The influence on experimental frequency response due to friction disturbances at low frequency and modeling u...

Wireless LANs with their increased data rate become an attractive technology for connecting mobile users to the Internet. Efficient deployment of wireless LANs will require the ability to extend the wireless LANs coverage without the need to deploy a very large number of access points. Mesh based wireless LANs are an attractive solution to this problem. These networks extend the wireless LAN co...

This study integrates path planning, fuzzy theory, neural networks, image processing, range sensors, webcam, global navigation satellite system (GNSS), and real-time kinematic (RTK) positioning into an intelligent wheeled mobile robot (WMR) for outdoor patrolling. The uses ultrasound laser controllers to detect obstacles avoid them. starting position the goal of WMR in environment are given by ...

The control system of a mobile robot generally comprises two different modules: a trajectory planner and a trajectory tracking controller, although some researchers have proposed algorithms that integrate both tasks. To completely solve the trajectory planning problem is to define an open-loop path and its velocity profile from an initial to a final posture, while avoiding any potential obstacl...

As the speed and payload of Wheeled Mobile Robots (WMRs) increases and the clearances between obstacles and docking error tolerances decreases, methods for reducing tracking errors become increasingly important for a successful application. In this paper techniques and results are presented for improved tracking control of a WMR through the generation and dynamic simulation of paths with and wi...

Background Within medical education, there have been recent calls for increased understanding and exposure to poverty to increase trainees' empathy toward the underserved. Students participating in Michigan Cardiovascular Outcomes Research and Reporting Program research program volunteered at World Medical Relief (WMR) in Detroit, Michigan, a nonprofit organization which recycles medical equipm...

 review current methods in malaria morbidity and mortality estimation with the participation of the experts involved in the development of currently used methods,  try to achieve consensus on the methods that should be used by WHO and in the World Malaria Report (WMR), and  identify research bottlenecks that prevent reconciliation of different methodologies/results and how these may be addre...
