A Lower Bound for Testing 3-Colorability in Bounded-Degree Graphs
We consider the problem of testing 3-colorability in the bounded-degree model. We show that, for small enough ε, every tester for 3colorability must have query complexity Ω(n)....

A low power direct digital frequency synthesizer with 60 dBc spectral purity
We present a low-power sine-output Direct Digital Frequency Synthesizer (DDFS) realized in 0.18 µm CMOS that achieves 60 dBc spectral purity from DC to the Nyquist frequency. No ...

A symbolic model approach to the digital control of nonlinear time-delay systems
— In this paper we propose an approach to control design of nonlinear time–delay systems, which is based on the construction of symbolic models, where each symbolic state and e...
