, 2006
This paper develops the theory of abelian Routh reduction for discrete mechanical systems and applies it to the variational integration of mechanical systems with abelian symmetry.

An Effective Corner Increment-Based Algorithm for the Two-Dimensional Strip Packing Problem

IEEE Access, 2018
The 2-D strip packing problem is an NP-hard combinatorial optimization problem. Given a strip with fixed width and infinite height, the aim of strip packing is to pack a set of rectangles with known widths and heights into the strip such that the used ...

Statistical analysis of vegetable productivity dynamics of Uzbekistan [PDF]

BIO Web of Conferences, 2023
In all fields, there are a lot of random events at a given time. In particular, the process of growing agricultural crops, which is repeated over a certain period, that is, seasonally, is the basis for our analysis as a discrete {Yt,t ∈ T} random dynamic

Euler-Poincare reduction for discrete field theories [PDF]

, 2007
In this note, we develop a theory of Euler-Poincare reduction for discrete Lagrangian field theories. We introduce the concept of Euler-Poincare equations for discrete field theories, as well as a natural extension of the Moser-Veselov scheme, and show ...

Storage sizing for embedding of local gas production in a micro gas grid

EPJ Web of Conferences, 2014
In this paper we study the optimal control of a micro grid of biogas producers. The paper considers the possibility to have a local storage device for each producer, who partly consumes his own production, i.e. prosumer.

Shields-Harary numbers of graphs with respect to continuous concave cost functions

International Journal of Mathematics and Mathematical Sciences, 2003
The Shields-Harary numbers are a class of graph parameters that measure a certain kind of robustness of a graph, thought of as a network of fortified reservoirs, with reference to a given cost function.

Proximity Effect Aware Detailed Placement in Electron Beam Lithography

MATEC Web of Conferences, 2018
Proximity effect is one of the most tremendous consequences that produces unacceptable exposures during electron beam lithography (EBL), and thus distorting the layout pattern. In this paper, we propose the first work which considers the proximity effect

T-Spline Based Unifying Registration Procedure for Free-Form Surface Workpieces in Intelligent CMM

Applied Sciences, 2017
With the development of the modern manufacturing industry, the free-form surface is widely used in various fields, and the automatic detection of a free-form surface is an important function of future intelligent three-coordinate measuring machines (CMMs)

SS-discrete modules [PDF]

Filomat, 2020
In this paper, we define (strongly) ss-discrete, semi-ss-discrete and quasi-ss-discrete modules as a strongly notion of (strongly) discrete, semi-discrete and quasi-discrete modules with the help of ss-supplements in [3]. We examined the basic properties of these modules and included characterization of strongly ss-discrete modules over ...
