Copyright © 2007 Massachusetts Medical Society. A 62-year-old man is admitted with fever, cough, and dyspnea. He is weak, appears to be dehydrated, and has purulent sputum. His temperature is 39.2°C, respirations 22, and blood pressure 128/69 mm Hg. There are crackles over the left lower lung field, and chest radiography shows a density in the left lower lobe that is consistent with pneumonia. ...

Some common fixed point theorems for Cq-commuting generalized nonexpansive mappings have been proved in metric spaces. As applications, invariant approximation results are also obtained. The results proved in the paper extend and generalize several known results including those of M. Abbas and J.K. Kim [Bull. Korean Math. Soc. 44(2007) 537-545], I. Beg, N. Shahzad and M. Iqbal [Approx. Theory A...

Indian J Med Sci, Vol. 62, No. 7, July 2008 In order to investigate the professionals’ adherence to measures o f s tandard precautions, we conducted a study at the 550-bed Imam Reza Teaching Hospital, Kermanshah, in September 2007. A total of 120 health care workers (nurses and paramedical staff) from different departments were surveyed using a standardized questionnaire. Data were analyzed usi...

This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in real-time in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The...

We present the motion planning framework for an autonomous vehicle navigating through urban environments. Such environments present a number of motion planning challenges, including ultrareliability, high-speed operation, complex intervehicle interaction, parking in large unstructured lots, and constrained maneuvers. Our approach combines a model-predictive trajectory generation algorithm for c...
