Most productivity measures are geared toward easy quantification, tending to evaluate the efficiency of an individual, group, organization, or country. But to help ensure productivity and quality, ...organizations need a new definition of productivity that takes into account a multitude of factors beyond inputs and outputs. These factors and their relative importance must be solicited from management. This article details a new, improved definition of productivity and explains bow organizations can apply it to their own situations.
We present ephemerides and solutions of one Algol-type (KZ Dra) and two overcontact systems (LR Cam and IM Vul) based on V (RI)c CCD observations obtained in the project Prosper (network of amateur ...observers).

Ten mobile robots entered the AAAI '92 Robot Competition, held at last year's national conference. Carmel, the University of Michigan entry, won. The competition consisted of three stages. The first ...stage required roaming a 22times22-meter arena while avoiding static and dynamic obstacles; the second involved searching for and visiting 10 objects in the same arena. The obstacles were at least 1.5 meters apart, while the objects were spaced roughly evenly throughout the arena. Visiting was defined as moving to within two robot diameters of the object. The last stage was a timed race to visit three of the objects located earlier and return home. Since the first stage was primarily a subset of the second-stage requirements, and the third-stage implementation was very similar to that of the second, the authors' focus here on the second stage. Carmel (Computer-Aided Robotics for Maintenance, Emergency, and Life support) is based on a commercially available Cybermotion K2A mobile-robot platform. It has a top speed of approximately 800 millimeters per second and moves on three synchronously driven wheels. For sensing, Carmel, has a ring of 24 Polaroid sonar sensors and a single black-and-white charge-coupled-device camera mounted on a rotating table. Carmel has three processors: one controls the drive motors, one fires the sonar ring, and the third, a 486-based PC clone, executes all the high-level modules. The 486 also has a frame grabber for acquiring images. All computation and power are contained on-board.
