In this paper, and mixed / controllers are designed for a hard disk drive (HDD) using linear matrix inequalities (LMIs). In the proposed algorithm, the problem of minimizing track misregistration (TMR) in the presence of unmodeled dynamics of voice-coil motor (VCM) is formulated as robust and mixed / problems. Additional stack variables are introduced to characterize and performances. The simul...

Like many other species of diadromous fish, the European eel (Anguilla anguilla) is threatened by entrainment at hydropower intakes and resultant injury mortality during passage through turbines. Historically, physical screens have been installed to prevent access but these are not wholly effective can incur high costs construction maintenance, especially when regulations require screen retrofi...

A 10-bit 120MS/s successive-approximation-register (SAR) analog-to-digital converter (ADC) in 40-nm CMOS is presented. To diminish the fluctuation of common-mode voltage (VCM) and switching energy during conversion, a VCM-stable scheme adopted without increasing design complexity to VCM buffers. Moreover, tri-switch sampling employed this design. Together with binary-scaled recombination weight...

Stereotype research depicts the generic immigrant as incompetent and untrustworthy. The current research expands this image, specifying key information dimensions (e.g. nationality, socioeconomic status) about immigrants. To see how perceivers differentiate among particular immigrant groups, we extend a model of intergroup perception, the Stereotype Content Model (SCM; Fiske, Cuddy, Glick, & Xu...
