Optimal and near-optimal partner selection algorithms in cooperative OFDMA
(IEEE, 2012)
We obtain the jointly optimal power allocation and partner selection policies, that maximize the sum rate of a cooperative OFDMA system with mutually cooperating pairs of users. We show that the power allocation and partner ...
An analog integrated circuit beamformer for high-frequency medical ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2012-10)
We designed and fabricated a dynamic receive beamformer integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer IC is suitable for integration with an annular array transducer for high-frequency (30-50 MHz) ...
Photogrammetric monitoring of an artificially generated shallow landslide
(Wiley-Blackwell, 2013-06)
An artificial rainfall event was applied to a forested slope in Ruedlingen, northern Switzerland. The experiment triggered a landslide which resulted in mobilising about 130m3 of debris. The event was monitored by a ...
The republican people's party and Turkey's EU membership
(Routledge Journals, Taylor & Francis Ltd, 2011-09)
As the founder of the Turkish secular state, the Republican People's Party (CHP) has defended the Westernisation of Turkish society, supported Turkey's acceptance to the EU as a full member, and played crucial roles in ...
Jointly optimal chunk and power allocation in uplink SC-FDMA
(IEEE, 2013)
For a single carrier frequency division multiple access (SC-FDMA) system, we obtain the jointly optimal power and chunk allocation policies which maximize the sum rate. Our solution is applicable to both localized and ...
Cryptanalysis of Fridrich's chaotic image encryption
(World Scientific Publishing, 2010-05)
We cryptanalyze Fridrich's chaotic image encryption algorithm. We show that the algebraic weaknesses of the algorithm make it vulnerable against chosen-ciphertext attacks. We propose an attack that reveals the secret ...
