This paper examines the reasons for design iteration and describes models of design iteration. Iteration is the process of repeating tasks within a design project, and is common to all types of engineering design. Iteration is typically necessary for two reasons: an unexpected failure of a design or prototype to meet established criteria; and an expected response to information which was genera...

In this paper, several $Delta$ and strong convergence theorems are established for the Ishikawa iterations for nonexpansive mappings in the framework of CAT(0) spaces. Our results extend and improve the corresponding results

the polarographic reduction of aromatic carbodiimides in anhydrous aprotic solvents goes through a carbene intermediate by a diffusion controlled process in two one-electron steps. the first step is the rate-determining step and converts the carbodiirnide to a radical anion (6) that reduces further by a fast one-electron step to a carbene dianion intermediate (7). this abstracts an oxygen, alon...

Partially Observable Markov Decision Processes (POMDPs) provide an elegant framework for AI planning tasks with uncertainties. Value iteration is a well-known algorithm for solving POMDPs. It is notoriously difficult because at each step it needs to account for every belief state in a continuous space. In this paper, we show that value iteration can be conducted over a subset of belief space. T...
