In iterative learning control (ILC), it is highly desirable to have a learning compensator with a unitgain for all frequencies, in order to avoid noise amplification and learning speed degradation during the learning process. In this paper, we show that the realization of a unit-gain compensator is straightforward in ILC, using both forward and backward filtering. As an illustrative example, a ...

lationship), superfamilies (probable common evolutionary origin) and folds (Murzin et al., 1995). Proteins are defined to have a common fold if they have the same major secondary structures in the same spatial arrangement and the same topological connections. SCOP currently distinguishes between several hundred different folds. The (βα)8(or TIM-)barrel is a frequently encountered fold, which co...

introduction: barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. on the other hand, norepinephrine (ne) and locus coeruleus, which is the main source of ne, influenced response properties of cortical barr...

Whisker deflection is an effective conditioned stimulus (CS) for trace eyeblink conditioning that has been shown to induce a learning-specific expansion of whisker-related cortical barrels, suggesting that memory storage for an aspect of the trace association resides in barrel cortex. To examine the role of the barrel cortex in acquisition and retrieval of trace eyeblink associations, the barre...

26 A growing body of evidence suggests that the barrel and septal regions in layer IV of rat primary 27 somatosensory (SI) cortex may represent separate processing channels. To assess this view, pairs of barrel 28 and septal neurons were recorded simultaneously in the anesthetized rat while a 4 x 4 array of 16 whiskers 29 was mechanically stimulated at 4, 8, 12, and 16 Hz. Compared to barrel ne...

It is known that an axial piston pump barrel experiences small oscillations due to forces acting over it. Cavitation als o occurs in many cases, damaging the plate and barrel sliding surfaces and therefore reducing the volumetric and overall efficiency of the pump. More importantly, the resulting failure of the pump is often a critical issue in modern industrial applications. The complex fluctu...

Barrel Shifter plays an important role in the data shifting and data rotation. It is having application in many areas. The Barrel Shifter is mainly use for the simplification of the data shifting. The Arithmetic and the Logical Shifters can also be replaced by the Barrel Shifter Because with the rotation of the data it also provide the application the data right, left shifting either arithmetic...

The FhuA protein in the outer membrane of Escherichia coli actively transports ferrichrome and the antibiotics albomycin and rifamycin CGP 4832 and serves as a receptor for the phages T1, T5, and phi80 and for colicin M and microcin J25. The crystal structure reveals a beta-barrel with a globular domain, the cork, which closes the channel formed by the barrel. Genetic deletion of the cork resul...
