    • An algorithmic proof of the polyhedral decomposition theorem 

      Akgül, M. (John Wiley & Sons, 1988)
      It is well‐known that any point in a convex polyhedron P can be written as the sum of a convex combination of extreme points of P and a non‐negative linear combination of extreme rays of P. Grötschel, Lovász, and Schrijver ...
    • A sequential dual simplex algorithm for the linear assignment problem 

      Akgül, M. (Elsevier, 1988)
      We present a sequential dual-simplex algorithm for the linear problem which has the same complexity as the algorithms of Balinski [3,4] and Goldfarb [8]: O(n2) pivots, O(n2 log n + nm) time. Our algorithm works with the ...
    • C∗-actions on Grassmann bundles and the cycle at infinity. 

      Sertöz, S. (Aarhus Universitet * Mathematica Scandinavica, 1988)
      We describe the Grassmann Graph construction of MacPherson in the analytic category using a C∗-action and the corresponding BialynickiBirula decomposition. It is shown that the cycle at infinity is analytic in the compact ...
    • Coding method for discrete noiseless channels with input constraints 

      Arıkan, Erdal (IEEE, 1988)
      Summary form only given. Two coding algorithms for discrete noiseless channels with input constraints have been analyzed. The first algorithm, which requires infinite-precision arithmetic and is mainly of theoretical ...
    • Sorption of cesium and strontium on montmorillonite and kaolinite

      Sorption characteristics of Cs+ and Sr++on montmorillonite and kaolinite type clays and soil fractions from various regions of Turkey were studied using the batch method. 137Cs and 90Sr were used as tracers. Concentrations ...
    • Critical relaxation of the two-dimensional three-state Potts model with conserved dynamics 

      Aydın, M.; Yalabık, M. C. (Institute of Physics (Great Britain), 1988)
      The dynamical critical exponent z is obtained using the finite-size scaling method for the two-dimensional three-state Potts model with conserved dynamics. It is observed that there is a change in the dynamical behaviour ...
    • An Upper Bound on the Cutoff Rate of Sequential Decoding 

      Arikan, E. (1988)
      An upper bound is given on the cutoff rate of discrete memoryless channels. This upper bound, which coincides with a known lower bound, determines the cutoff rate, and settles a long-standing open problem. © 1988 IEEE
    • Sequential decoding for multiple access channels 

      Arıkan, E. (Institute of Electrical and Electronics Engineers, 1988)
      The use of sequential decoding in multiple access channels is considered. The Fano metric, which achieves all achievable rates in the one-user case, fails to do so in the multiuser case. A new metric is introduced and an ...
