Edge detection based on augmented lagrangian method for lowquality medical images
Ho Chi Minh City Open University Journal of Science - Engineering and Technology, 2018 Medical images are useful for the treatment process. They contain a lot of information on displaying abnormalities in your body. The contour of medical images is a matter of interest.

A note on embeddings for the Augmented Lagrange Method [PDF]
Yugoslav Journal of Operations Research, 2010 Nonlinear programs (P) can be solved by embedding problem P into one parametric problem P(t), where P(1) and P are equivalent and P(0), has an evident solution.

Superfield Approach to Nilpotent Symmetries of the Freedman-Townsend Model: Novel Features
, 2012 We perform the Becchi-Rouet-Stora-Tyutin (BRST) analysis of the Freedman-Townsend (FT) model of topologically massive non-Abelian theory by exploiting its (1-form) Yang-Mills (YM) gauge transformations to show the existence of some novel features that ...

International Transactions in Operational Research, EarlyView.Abstract We propose the novel p‐branch‐and‐bound method for solving two‐stage stochastic programming problems whose deterministic equivalents are represented by non‐convex mixed‐integer quadratically constrained quadratic programming (MIQCQP) models. The precision of the solution generated by the p‐branch‐and‐bound method can be arbitrarily adjusted by

Generalized Quadratic Augmented Lagrangian Methods with Nonmonotone Penalty Parameters
Journal of Applied Mathematics, 2012 For nonconvex optimization problem with both equality and inequality constraints, we introduce a new augmented Lagrangian function and propose the corresponding multiplier algorithm. New iterative strategy on penalty parameter is presented.

Augmented Lagrangian Approach to the Newsvendor Model with Component Commonality
Mathematical and Computational Applications, 2019 Component commonality is a well-known approach in manufacturing, where the same components are used for multiple products. It has been implemented by many established companies such as Airbus, Kodak, Toyota, etc.

A new family of models with generalized orientation in data envelopment analysis
International Transactions in Operational Research, EarlyView.Abstract In the framework of data envelopment analysis, we review directional models and show that they are inadequate when inputs and outputs are improved simultaneously under constant returns to scale. Conversely, we introduce a new family of quadratically constrained models with generalized orientation and demonstrate that these models overcome this

Three-dimensional topologically gauged N=6 ABJM type theories
, 2010 In this paper we construct the $\mathcal N=6$ conformal supergravity in three dimensions from a set of Chern-Simons-like terms one for each of the graviton, gravitino, and R-symmetry gauge field and then couple this theory to the $\mathcal N=6 ...
