In March 2004, the National Assembly of South Korea impeached President Roh Moo-hyun and brought about an immediate suspension of Roh's presidency. Two months later, the Constitutional Court of Korea restored the status quo by dismissing the impeachment and reinstating the President. This episode marks the first time in the history of modern constitutionalism that a president impeached by a leg...

Base metal promoted gold/titania catalysts were synthesized, characterized and tested in CO oxidation reaction. Catalysts containing dopant metals in higher oxidation states exhibited higher activity than catalysts containing dopants in reduced states. The activity of fresh catalysts promoted by Cu, Fe and Ni was similar to the unpromoted one, but treatment in reducing and oxidizing atmospheres...

We introduce a new microarchitectural timing covert channel using the processor memory order buffer (MOB). Specifically, we show how an adversary can infer the state of a spy process on the Intel 64 and IA-32 architectures when predicting dependent loads through the store buffer, called 4K-aliasing. The 4K-aliasing event is a side-effect of memory disambiguation misprediction while handling wri...

This contribution deals with the design of a fully digital multi-rate receiver, operating on non-synchronized bandpass samples. Issues related to aliasing, sample rate conversion and timing correction are considered. We compare various receiver alternatives in terms of the BER degradation caused by aliasing and non-ideal timing correction. In particular, we focus on a low-complexity receiver pe...
