The author considers two basic problems with repetitive control: the tight stability condition and the poor noise characteristics. He presents three techniques for a practical repetitive controller design: stabilizing compensation by an inverse phase system, band limitation of the control, and smoothing of the control signal over periods of repetitive operation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

The boron-mediated aldol reaction of carboxylic esters is described in detail. Contrary to the general belief that carboxylic esters are inert under the condition of the boron enolate formation, propionate esters are enolized with certain combinations of a boron triflate and an amine. More importantly, the stereochemical course of the aldol reaction can be controlled by the judicious selection of the enolization reagents. Treatment of propionate esters with c-Hex2BOTf and triethylamine produces

Young's modulus of amorphous polymers around the glass-to-rubber transition zone can be separated into two component functions (R and G) through a modified stress-optical rule (Inoue et al. Macromolecules 1991, 24, 5670) with the simultaneous measurements of the strain-induced birefringence and the stress. In the present study, the two component functions are compared among more than ten polymers, and their relation to chemical structure is investigated. The Rouse segment size is estimated from

High-level radioactive wastes from the Purex process contain long-lived nuclides, which mainly consist of transuranic elements (TRUs). A partitioning and transmutation method that consists of pyrometallurgical partitioning of TRUs from Purex waste from light water reactor fuel and transmutation using a metal-fueled fast breeder reactor (FBR) is evaluated. The results indicate that the concept is feasible and has many advantages over conventional concepts based on wet processes and that transmuta

Latent TGF-β-binding protein-2 (LTBP-2) is an extracellular matrix protein associated with microfibrils. Homozygous mutations in LTBP2 have been found in humans with genetic eye diseases such as congenital glaucoma and microspherophakia, indicating a critical role of the protein in eye development, although the function of LTBP-2 in vivo has not been well understood. In this study, we explore the in vivo function of LTBP-2 by generating Ltbp2(-/-) mice. Ltbp2(-/-) mice survived to adulthood but

The iodocarbocyclization reaction of 4-alkenylmalonate derivatives proceeded with excellent enantioselectivity (>/=95% ee) in the presence of 10-40 mol % of Ti(TADDOLate)(2). The Ti(TADDOLate)(2)-mediated catalytic asymmetric reaction was extended to the enantiotopic group selective reaction of bisalkenylated malonates, giving rise to trisubstituted cyclopentanoid compounds with both high diastereoselectivity (86-94% de) and excellent enantioselectivity (>/=95% ee). An efficient synthesis of (+)

The nonlinear rheology of aqueous solutions of cetyltrimethylammonium bromide (CTAB) and sodium salicylate (NaSal) was investigated. The concentration of CTAB was fixed at 0.1 mol L(-1), and the concentration of NaSal was varied from 0.07 to 0.4 mol L(-1). For all test solutions, dynamic moduli were described with the Maxwell model having a single relaxation time, tau. Time evolutions of the shear stress, sigma, and the first normal stress difference, N(1), after inception of the steady shear fl
