We analyse emission spectra of WASP-12b from a partial phase curve observed over three epochs with the Hubble Space Telescope, covering eclipse, quadrature, and transit, respectively. As 1.1-day period was only partially covered epochs, traditional methods to extract planet flux instrument systematic errors cannot recover thermal away secondary eclipse. To this curve, we introduce new method, w...
analytical solutions and type curves for the constant rate radial flow of fluid in both conventional and naturally fractured reservoirs including the effect of wellbore phase redistribution are presented. an automated procedure for non-linear least square minimization using the analytical solutions and their derivatives with respect to the unknown parameters developed to analyze the pressure bu...
in this note we review a simple criterion, due to ekedahl, for superspecial curves defined over finite fields.using this we generalize and give some simple proofs for some well-known superspecial curves.
A conceptually simple method for linac tuning has been tested on the 200 MeV drift-tube linear accelerator at Fermilab. The phase of a beam-induced signal in a stripline detector is measured as tank phase is scanned over approximately 360 degrees. The stripline detector is downstream of the tuned tank. The resulting phase-scan curves have unique signatures that depend upon only a few critical p...
Nano-structured hydroxyapatite doped with europium in different mole percentages of 1 to 5 have been synthesized using a hydrolysis route. Structural and thermoluminescence (TL) properties of the samples have been discussed in detail. Powder X-ray diffraction and scanning electron microscopy confirm the phase purity and nano structure nature of synthesized powder. The samples were irradiated by...
The existing standards for measuring carpet properties consider carpet behavior after loading while its dynamic and instantaneous behavior is neglected. To investigate the dynamic behavior of under loading carpets, an INSTRON machine equipped with a developed system was used. The reliability of the system was verified by testing different materials. Different samples of hand-knitted carpet with...
ACKNOWLEDGEMENTS I would like to thank my adviser Michael Zieve for teaching me to fish. I would like to thank Jeffrey Lagarias for helpful feedback in writing this thesis. I would like to thank my family (Peter, Susan, and Holly), my beautiful girlfriend Becky, and the community of Michigan graduate students for keeping me sane.
[1] The strong jet, with a speed between 500 and 600 m/s, is inferred in the equatorial region of Saturn by combining the nadir and limb observations of Composite Infrared Spectrometer (CIRS) aboard the Cassini spacecraft. A similar jet was discovered on Jupiter (F. M. Flasar et al., 2004a). These discoveries raise the possibility that intense jets are common in the equatorial stratospheres of ...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
