Test problems for large-scale nonsmooth minimization
(University of Jyväskylä, 2007)Many practical optimization problems involve nonsmooth (that is, not necessarily differentiable) functions of hundreds or thousands of variables with various constraints. However, there exist only few large-scale academic ... -
Limited memory bundle algorithm for large bound constrained nonsmooth minization problems
(University of Jyväskylä, 2006)Typically, practical optimization problems involve nonsmooth functions of hundreds or thousands of variables. As a rule, the variables in such problems are restricted to certain meaningful intervals. In this paper, we ... -
Large-scale nonsmooth optimization: new variable metric bundle algorithm with limited memory

Limited memory bundle algorithm for inequality constrained nondifferentiable optimization
(University of Jyväskylä, 2007)Many practical optimization problems involve nonsmooth (that is, not necessarily differentiable) functions of hundreds or thousands of variables with various constraints. In this paper, we describe a new efficient ... -
An analytical-numerical study of dynamic stability of an axially moving elastic web
(Jyväskylän yliopisto, 2015)This paper is devoted to a dynamic stability analysis of an axially moving elastic web, modelled as a panel (a plate undergoing cylindrical deformation). The results are directly applicable also to the travelling beam. ... -
Variational principle and bifurcations in stability analysis of panels
(Jyväskylän yliopisto, 2014)In this paper, the stability of a simply supported axially moving elastic panel is considered. A complex variable technique and bifurcation theory are applied. As a result, variational equations and a variational principle ... -
Bifurcation method of stability analysis and some applications
(Jyväskylän yliopisto, 2014)In this paper a new approach to the analysis of implicitly given function- als is developed in the frame of elastic stability theory. The approach gives an effective procedure to analyse stability behaviour, and to ... -

On static instability and estimates for critical velocities of axially moving orthotropic plates under inhomogeneous tension
(University of Jyväskylä, 2012)In this study, models for axially moving orthotropic plates are investigated analytically. Linearised Kirchhoff plate theory is used, and the energy forms of steady-state models are considered. With the help of the energy ... -
Multi-objective actuator placement optimization for local sound control evaluated in a stochastic domain
(Jyväskylän yliopisto, 2011)A method to find optimal locations and properties of anti-noise actuators in local noise control system is considered. The local noise control performance is approximated by a finite element method based approach, that ... -
Java-COM integration with JACOB using XML wrappers
(University of Jyväskylä, 2006)Many Windows-based legacy applications can be programmatically accessed using COM interfaces. However, calling COM components from Java is not straightforward. This report compares four open source Java-COM integration ...
