We present a method useful in solving a special class of large-scale multiobjective integer problems depending on the decomposition algorithm. These problems involve fuzzy parameters on the right-hand side of the independent constraints. The presented solution method is based upon a combination of the decomposition algorithm coupled with the weighting(More)
Fuzzy Heat exchanger network synthesis problem (F-HEN) is formulated as a multi-objective mixed-integer nonlinear programming (F-MO-MTNLP) to handle the multiple objectives of minimum utility consumption, minimum total area, and even minimum number of matches. Heat-capacity flow rates are proposed as fuzzy variables. The nonlinear G-bell membership function(More)
Multiple-Input Multiple-Output (MIMO) systems using orthogonal frequency-division multiplexing (OFDM) technique provide promising features for the next generation communication systems. MIMO-OFDM systems can be enhanced using Space-Time Coding (STC). In this paper we introduce a combined Alamouti Space Time Block Coding/Repetition coding (STBC/STRC) with(More)
BACKGROUND Cardiac glycosides (CGs) including digitalis, digoxin and digitoxin are used in the treatment of congestive heart failure and atrial fibrillation. Pre-clinical studies have investigated the anti-neoplastic properties of CGs since 1960s. Epidemiological studies concerning the association between CGs use and cancer risk yielded inconsistent(More)
