CVTresh: R Package for Level-Dependent Cross-Validation Thresholding
No full textThe core of the wavelet approach to nonparametric regression is thresholding of wavelet coefficients. This paper reviews a cross-validation method for the selection of the thresholding value in wavelet shrinkage of Oh, Kim, and Lee (2006), and introduces the R package CVThresh implementing details of the calculations for the procedures. This procedure is implemented by coupling a conventional cross-validation with a fast imputation method, so that it overcomes a limitation of data length, a power of 2. It can be easily applied to the classical leave-one-out cross-validation and K-fold cross-validation. Since the procedure is computationally fast, a level-dependent cross-validation can be developed for wavelet shrinkage of data with various sparseness according to levels.

Efficient on-chip decoupling capacitor design on an 8-bit microcontroller to reduce simultaneous switching noise and electromagnetic radiated emission
No full textWe have thoroughly investigated the effect of on-chip decoupling capacitors on the simultaneous switching noise (SSN) and the radiated emission. Furthermore, we have successfully demonstrated an efficient design method for on-chip decoupling capacitors on an 8-bit microcontroller without increasing the die size, which results in more than 10 dB of suppressed radiated emission.The authors are grateful to Young-hwan Yun, Seog-heon Ham, Yong-hee Lee and Do-won Kim of Samsung Electronics, who provided the test IC chip layout and fabrication. We would like to thank D.K.Han, Y.S.Park, H.J.Yoon and M.K.Oh of Hynix Semiconductor for the fabrication of the controller IC chip being tested.

DEVELOPMENT OF SYNTHETIC SPECIMENS FOR CALIBRATION AND EVALUATION OF M SUB R (RESILIENT MODULUS) EQUIPMENT
No full textLaboratory measurement of the deformational characteristics of subgrade materials can be quite difficult because of the small values of stress and strain typically involved and the need to eliminate equipment compliance. Measurement of resilient modulus (M sub R) of subgrades falls into this category. Therefore, synthetic specimens with known stiffness characteristics would be beneficial in evaluating and calibrating M sub R equipment as well as training personnel. Two-component urethane elastomer resins are shown to make good candidates for calibration specimens. They can be made with a wide range of stiffnesses that vary from soft subgrades to stiff uncemented bases. Urethane can be modeled as a linear, viscoelastic material with stiffness characteristics essentially independent of confining pressure, strain amplitude, and stress history for the type of cyclic loading used in M sub R testing. Urethane stiffness is, however, dependent on loading frequency and temperature. Therefore, values of Youngs modulus used to equate to M sub R have to be selected at the appropriate frequency and temperature
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
