Lagrangian approach to Geometric Quantization

, 2019
The Lagrangian approach to Geometric Quantization is based on realizing Lagrangian submanifolds of a given classical phase space as quantum states. Geometrically it is clear how the corresponding quantum dynamics can be derived, but the necessary measurement process cannot be defined unless one introduces some additional data (e.g.

A finite element model for surface and volumetric defects in the FSW process using a coupled Eulerian–Lagrangian approach

Science and technology of welding and joining, 2021
The friction stir welding (FSW) process is often associated with various defects, which may develop due to the inappropriate choice of process parameters. The visualisation of the defects is often impossible by means of simple experiments.

A Lagrangian approach for the minimum spanning tree problem with conflicting edge pairs

Networks, 2020
This article addresses the minimum spanning tree problem with conflicting edge pairs, a variant of the classical minimum spanning tree where, given a list of conflicting edges, the goal is to find the cheapest spanning tree with no edges in conflict.

A Lagrangian Approach to Optimal Design

Biometrika, 1974
where u is a column vector of k components and prime denotes transpose. The D-optimal design problem is to determine a A which maximizes log det M(A). Now log det is a concave function on the set of nonnegative-definite symmetric matrices and so the D-optimal problem can be regarded as a particular case of the following one, which we shall call the qs ...

Suspension bridge analysis using lagrangian approach

Computers & Structures, 1987
A general analysis of the static and dynamic responses of suspension bridges is presented. The Cullmann 'elastic weight' theory is revisited, and it is shown to be a powerful discretization tool. According to this method, the stucture is reduced to a system of lumped masses and elastic springs, so that it can be considered as a classic holonomic system

A Lagrangian relaxation approach for the electric bus charging scheduling optimisation problem

Transportmetrica A: Transport Science, 2022
The planning and operational decision-making problems of electric transit systems have received significant attention recently in the process of transport electrification. Given an electrified electric transit system with constructed charging facilities,
