Combining Subset Selection and Parameter Constraints in Model Updating

Parameter Selection Strategies in Finite Element Model Updating

In FE model updating, as in any identification procedure, we select some parameters in the model, and try to fine-tune them to minimize the discrepancy between the model predictions and the measured data. The paper compares the performance of the generic element matrices, recently introduced by the authors, with other selection strategies for finite element model updating. The updated models ob...

Subset Selection for Improved Parameter Estimation

In this paper we discuss methods for subset selection for a non-linear least squares parameter estimation problem. Through the use of these algorithms, we partition the parameter space into a linear independent and a linearly dependent set. By identifying these subsets, we are able to gain further into model dynamics. We then apply subset selection techniques to a simplified model describing th...

On Subset Selection with General Cost Constraints

This paper considers the subset selection problem with a monotone objective function and a monotone cost constraint, which relaxes the submodular property of previous studies. We first show that the approximation ratio of the generalized greedy algorithm is α2 (1 − 1 eα ) (where α is the submodularity ratio); and then propose POMC, an anytime randomized iterative approach that can utilize more ...

New Barrier Parameter Updating Technique in Mehrotra-Type Algorithm

a contrastive analysis of concord and head parameter in english and azerbaijani

این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
