Phenomenological and global optimization inversion
- Marine Physical Laboratory, University of California, San
, 1984
"... Abstract—This paper discusses geoacoustic inversion results based on benchmark range-dependent data using SAGA, a global inversion package, and using phenomenological inversions. In phenomenological inversions, physical and signal-processing approaches are used to enhance the data to extract specifi ..."

Towards an Optimal Inversion Method
"... 1 In recent years, particular efforts have been made to derive wind fields over the oceans from SAR images. In contrast with the scatterometer, the SAR has a higher spatial resolution and therefore the potential to provide higher resolution wind information. Since there are at least two geophysical ..."

parameters (wind speed and wind direction) modulating the single SAR backscatter measurements, the inversion of wind fields from SAR observations has an inherent problem of underdetermination. Moreover, this modulation is highly non-linear, further complicating the inversion. Lorenc (1986) presented a

"... Abstract —Transformer design optimization is determined by minimizing the transformer cost taking into consideration constraints imposed both by international specifications and customer needs. The main purpose of this work is the development and validation of an optimization technique based on para ..."

"... Abstract — The paper introduces a novel technique for iron loss optimization of wound core shell type distribution transformers. Such a technique involves the evaluation of appropriate design variables of wound cores constructed by a combination of standard and high magnetization grade laminations. ..."

"... The pattern of zero entries in the inverse covariance matrix of a multivariate normal distribution corresponds to conditional independence restrictions between variables. Covariance selection aims at estimating those structural zeros from data. We show that neighborhood selection with the Lasso is a ..."

SVM Optimization: Inverse Dependence on Training Set Size
"... We discuss how the runtime of SVM optimization should decrease as the size of the training data increases. We present theoretical and empirical results demonstrating how a simple subgradient descent approach indeed displays such behavior, at least for linear kernels. 1. ..."

Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,
, 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

with before the theory can be fully applied to real-world job design problems. First, means must be developed for measuring current levels of activation of individuals in actual work settings (cf. Thayer, 1967), and for assessing the "optimal level" of activation for different individuals. Until
Optimal Inverse Simulation Of Helicopter Maneuvers
