This report describes the certification of SRM 1962, a NIST Standard Reference Material for particle diameter. It consists of an aqueous suspension of monosize 3 (μm polystyrene spheres. Two calibration techniques were used: optical microscopy and electron microscopy. The first one gave a mean diameter of [Formula: see text] μm and a standard deviation of the size distribution σD = 0.020 μm, ba...

This paper surveys the planning and reasoning research being carried out in the Robot Vision Lab at Purdue. In parlicular, we will describe the workings of a new planning system called SPAR, which uses a constraint posting approach for simultaneously fulfilling the operational, geometric and uncertainly reduction goals, and the PSEIKI system for evidential reasoning in a rangled hierarchy. We w...

This paper focuses on a new Stackelberg location problem on a network with demands whose weights are given uncertainly and vaguely. By representing them as fuzzy random variables, the optimal location problem can be formulated as a fuzzy random programming problem for finding Stackelberg equilibrium. By using both their α-level sets for fuzziness and their satisfaction level for a given probabi...

The objective is to solve the college physics problem of a block sliding down movable smooth wedge without friction anywhere using spatial-numeric perspective. drawing method used sum normal force and weight find acceleration. results are equivalent algebra within accuracy. result geometric construction with regular uncertainly was shown for case any horizontal applied force. For given force, a...

Multiple sensors and sensor fusion are commonly used to get more accurate information. The intuitive method to store multi-sensory data is using uncertain database because the sensors are not precise enough. Hence, like the top-k queries in traditional database, the top-k queries in uncertain databases are quite popular and useful due to its wide application. Although there are lots of top-k qu...
