    • A comprehensive approach to universal piecewise nonlinear regression based on trees 

      Vanli, N. D.; Kozat, S. S. (IEEE, 2014)
      In this paper, we investigate adaptive nonlinear regression and introduce tree based piecewise linear regression algorithms that are highly efficient and provide significantly improved performance with guaranteed upper ...
    • Dwell-time computation for stability of switched systems with time delays 

      Caliskan, S. Y.; Özbay, Hitay; Niculescu, S. I. (IET, 2013)
      The aim of this study is to find an improved dwell time that guarantees the stability of switched systems with heterogeneous constant time-delays. Piecewise Lyapunov-Krasovkii functionals are used for each candidate system ...
    • Lot sizing with piecewise concave production costs 

      Koca, E.; Yaman, H.; Aktürk, M. S. (Institute for Operations Research and the Management Sciences (I N F O R M S), 2014)
      We study the lot-sizing problem with piecewise concave production costs and concave holding costs. This problem is a generalization of the lot-sizing problem with quantity discounts, minimum order quantities, capacities, ...
    • Stability analysis of switched systems using Lyapunov-Krasovskii functionals 

      Çalişkan, S.Y.; Özbay, Hitay; Niculescu, S.-I. (Elsevier, 2011)
      Piecewise Lyapunov-Razumikhin functions are previously used for obtaining a lower bound for the dwell time of the switched time delay systems under the assumption that each candidate system is delay dependently stable. In ...
