In the framework of real-time optimization, measurements are used to compensate for effects of uncertainty. The main approach uses measurements to update the parameters of a process model. In contrast, the constraint-adaptation scheme uses the measurements ...
Three Cu-TiB2 alloys (0.45, 1.6, 2.5 wt.% TiB2) have been prepared by a combination of in situ reaction and rapid solidification under optimized conditions. The relationship between microstructure, properties and in situ reaction condition for these Cu-TiB ...
Econometric models play an important role in transportation analysis. Estimating more and more complex models becomes problematic. The associated log-likelihood function is highly nonlinear and non concave and the comlexity of the model requires constraint ...
Transformation invariance is an important property in pattern recognition, where different observations of the same object typically receive the same label. This paper focuses on a transformation invariant distance measure that represents the minimum dista ...
An efficient synthesis of functionalized 3-alkyl-3-cyanomethyl-2-oxindole by a palladium-catalyzed domino Heck-cyanation reaction has been developed. Reaction of ortho-iodoanilide with potassium ferro(II)cyanide in the presence of palladium acetate and sod ...
Challenges in real-time process optimization mainly arise from the inability to build and adapt accurate models for complex physico-chemical processes. This paper surveys different ways of using measurements to compensate for model uncertainty in the conte ...
We present in this paper a new complete method for distributed constraint optimization. This is a utility-propagation method, inspired by the sum-product algorithm. The original algorithm requires fixed message sizes, linear memory, and is time-linear in t ...
This paper describes the transaction support framework OPTIMA and its implementation for Ada 95. First, a transaction model that fits concurrent programming languages is presented. Then the design of the framework is given. Applications from many different ...

Metalation/trapping sequences applied to relatively inert, tert-alkyl substituted arenes tend to give poor yields unless the reagent is used in high concns. Under optimized conditions, even 1,4-bis(tert-butyl)benzene, 1,1,3,3-tetramethylindane and 1,1,2,2, ...
