Mieko Yamada Department of Applied Mathematics Konan University Okamoto, Higashinada-ku Kobe 658, Japan Partially balanced incomplete block designs, PBIBDs, are designs for which the property of balance of BIBD is relaxed. They are based on an association scheme. We introduce the concept of generalized relative difference sets, generalizing the concept of relative difference sets introduced by ...

We report on the self-assembly behaviour of two homologue series of rod-coil block copolymers in which, the rod, a pi -conjugated polymer, is maintained fixed in size and chemical structure, while the coil is allowed to vary both in molecular weight and chemical nature. This allows maintaining constant the liquid crystalline interactions, expressed by Maier-Saupe interactions, omega , while var...
