Finding function and form.
The ability to recreate Nature's molecules through chemical synthesis is undoubtedly one of the greatest triumphs of the human imagination. To date, thousands of natural products have been synthesized and targets that looked like an impossible task only recently, such as a single glycoform of erythropoietin, have been reached. An achievement that would have astonished researchers several decade...
متن کاملFunction finding in classification learning
The paper describes a method for extending domain models in classification learning by deriving new attributes from existing attributes. The process starts by finding functional regularities within each class. Such regularities are then treated as additional attributes in the subsequent classification learning process. The research revealed that these techniques can reduce the number of clauses...
متن کاملFinding the Best Coefficients in the Objective Function of a Linear Quadratic Control Problem
Finding the best weights of the state variables and the control variables in the objective function of a linear-quadratic control problem is considered. The weights of these variables are considered as two diagonal matrices with appropriate size and so the objective function of the control problem becomes a function of the diagonal elements of these matrices. The optimization problem which is d...
متن کاملFinding Function Clones in Web Applications
Many web applications use a mixture of HTML and scripting language code as the front-end to business services. Analogously to traditional applications, redundant code is introduced by copy-and-paste practices. Code duplication is a pathological form of software reuse because of its effects on the maintenance of large software systems. This paper describes how a simple semi-automated approach ca...
متن کاملFinding Supply Function Equilibria with Asymmetric Firms
Firms compete in supply functions when they offer a schedule of prices and quantities into a market; for example, this occurs in many wholesale electricity markets. We study the equilibrium behaviour when firms differ, both with regard to their costs and their capacities. We characterize the types of equilibrium solution that can occur. If the demand can be low enough for it to be met economica...
