ON LINEAR COMBINATIONS OF UNITS WITH BOUNDED COEFFICIENTS AND DOUBLE-BASE DIGIT EXPANSIONS
, 2012
"... Let o be the maximal order of a number field. Belcher showed in the 1970s that every algebraic integer in o is the sum of pairwise distinct units, if the unit equation u+v = 2 has a non-trivial solution u, v ∈ o ∗. We generalize this result and give applications to signed double-base digit expansion ..."

Study on the Two-wavelength Digital Holography Using Double Fourier Transform
, 2010
"... The size of a reconstructed image depends on the reconstruction distance and wavelength. The double fourier transform method is proposed to eliminate the dependence on the reconstruction distance and wavelength. We can get a fixed reconstructed image size by using the double fourier transform method ..."

method. Two wavelength digital holography is proposed to measure the step height, which is larger than a single wavelength. The two image size of different wavelength holograms should be the same in order to apply two wavelength digital holography. We use two wavelength digital holography and double
DIGITAL DOUBLE BARRIER OPTIONS: SEVERAL BARRIER PERIODS AND STRUCTURE FLOORS
"... Abstract. We determine the price of digital double barrier options with an arbitrary number of barrier periods in the Black-Scholes model. This means that the barriers are active during some time intervals, but are switched off in between. As an application, we calculate the value of a structure flo ..."

. MARKET EXPANSION OR MARGIN EROSION: THE DOUBLE-EDGED SWORD OF DIGITAL CONVERGENCE
"... Digital convergence enables firms in the computing, communications, and electronic consumer industries to design and launch multifunctional converged products. This presents firms with a significant opportunity for value creation and profit growth. At the same time, the increased substitutability be ..."

Exposing Digital Forgeries in Video by . . .
-
, 2009
"... We describe a technique for detecting double quantization in digital video that results from double MPEG compression or from combining two videos of different qualities (e.g., greenscreening). We describe how double quantization can introduce statistical artifacts that while not visible, can be quan ..."

Double Lobed Radio Quasars from the Sloan Digital Sky Survey Double Lobed Radio Quasars from the Sloan Digital Sky Survey
"... ABSTRACT We have combined a sample of 44 984 quasars, selected from the Sloan Digital Sky Survey (SDSS) Data Release 3, with the FIRST radio survey. Using a novel technique where the optical quasar position is matched to the complete radio environment within 450 ′′ , we are able to characterize the ..."

A 1.9-GHz wide-band IF double conversion CMOS receiver for cordless telephone applications
- IEEE Journal of Solid-State Circuits
, 1997
"... Rapid growth in the portable communications market has pushed designers to seek low-cost, low-power, highly integrated solutions for the RF transceiver. A number of recent efforts have concentrated on integrating many of the discrete radio receiver components in a low-cost silicon process such as CM ..."

such as CMOS [1][2]. This paper describes a prototype of a monolithic CMOS receiver that combines RF and baseband functionality by taking the carrier signal at the LNA input and producing a 10-bit digital baseband waveform. A Wide-Band Intermediate Frequency Double Conversion (WBIFDC) architecture is utilized
