    Opis:
    The problem of finite, partially glued to a fixed rigid base rod longitudinal vibrations damping by optimizing adhesive structural topology is investigated. Vibrations of the rod are caused by external load, concentrated on free end of the rod, the other end of which is elastically clamped. The problem is mathematically formulated as a boundary-value problem for onedimensional wave equation with attenuation and variable controlled coefficient. The intensity of adhesion distribution function is taken as optimality criterion to be minimized. Structure of adhesion layer, optimal in that sense, is obtained as a piecewise-constant function. Using Fourier real generalized integral transform, the problem of unknown function determination is reduced to determination of certain switching points from a system of nonlinear, in general, complex equations. Some particular cases are considered.

    Opis:
    Many real-world marketplaces involve some additional constraints to be addressed during the market clearing process. This is the case of various infrastructure sectors of the economy, where market commodities are associated with some elements of the infrastructure, e.g., elements of telecommunication, power transmission or transportation network. Transactions are allowed only if the infrastructure, modeled as a flow network, is able to serve them. Determination of the best offers is possible by solving the optimization problem, so called the Winner Determination Problem (WDP). We consider a new subclass of the WDP, i.e., the Network Winner Determination Problem (NWDP). We characterize different poblems in the NWDP class and analyze their computational complexity. The sharp edge of tractability for NWDP-derived problems is generally designated by integer offers. However, we show that some specific settings of the problem can still be solved in polytime. We also presents ome exemplary applications of NWDP in telecommunication bandwidth market and electrical energy balancing market.

    Opis:
    Distribution optimization of elastic material under elastic isotropic rectangular thin plate subjected to concentrated moving load is investigated in the present paper. The aim of optimization is to damp its vibrations in finite (fixed) time. Accepting Kirchhoff hypothesis with respect to the plate and Winkler hypothesis with respect to the base, the mathematical model of the problem is constructed as two–dimensional bilinear equation, i.e. linear in state and control function. The maximal quantity of the base material is taken as optimality criterion to be minimized. The Fourier distributional transform and the Bubnov–Galerkin procedures are used to reduce the problem to integral equality type constraints. The explicit solution in terms of two–dimensional Heaviside‘s function is obtained, describing piecewise–continuous distribution of the material. The determination of the switching points is reduced to a problem of nonlinear programming. Data from numerical analysis are presented.
