We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.

It is important to develop a reliable and high-throughput simulation method for predicting airflows in the installation planning phase of windmill power plants. This study proposes a two-stage mesh generation approach to reduce the meshing cost and introduces a hybrid parallelization scheme for atmospheric fluid simulations. The meshing approach splits mesh generation into two stages: in the first stage, the meshing parameters that uniquely determine the mesh distribution are extracted, and in the second stage, a mesh system is generated in parallel via an in situ approach using the parameters obtained in the initialization phase of the simulation. The proposed two-stage approach is flexible since an arbitrary number of processes can be selected at run time. An efficient OpenMP-MPI hybrid parallelization scheme using a middleware that provides a framework of parallel codes based on the domain decomposition method is also developed. The preliminary results of the meshing and computing performance show excellent scalability in the strong scaling test.

The recent progress on the research of Er 3+-doped fiber amplifier (EDFA) and laser (EDFL) in our laboratory is reported in this paper. A novel tandem two-stage EDFA configuration was achieved with a small signal gain of 41 dB, output power of 14.5 dBm (both at 1550 nm) and a bandwidth of more than 40 nm. In a novel coupled-ring EDFL, bi-directional simultaneous single longitudinal mode oscillation was accomplished with a laser linewidth of less than 1.0 GHz. By introducing polarization-evolution self-loss modulation in a LD pumped figure-8 all-fiber EDFL, correlated self Q-switching with variable period and mode-locking with low threshold were observed, respectively.
