This blog discusses green technology for radio access networks. Recently, mobile phones are including many digital functionalities such as enjoying mobile web services and playing music and video multimedia. This results in naturally increasing energy consumption of mobile phones so we wanna talk about this problems.

He declares 'God is not great'

-
Born in UK, Christopher Hitchens, 56, was chosen as the 5th most world-wide intellectual by professional readers conducted by 2 political and diplomatic magazines last year. He is following Noam Chomsky, Umberto Eco, Richard Dawkins and Vaclav Havel. He has been staying in America since 1980s and writing columns titling 'Minority Report' in 'The Nations'. He became generally known for the author of 'Hostage to History', 'For the Sake of Argument', 'The Missionary Position' and so on. Recently, he is also acknowledged politically being a sort of 'Neocon', after continuously criticizing left-wing of Anglo-America and Islamic fundamentalism. I am reading his book 'God is not Great', dealing with lots of gods and godness all over the world since the prehistoric age. Of cource, he mainly focuses on 2 big powers, 'Christianity' and 'Islam'. As an atheist and meterialist together with Richard Dawkins( Actually, I am sure...

Power of iPython

-
Currently, I started to use iPython command line, which is so convenient and much compatible with the commercial numerical simulation tool.  Since the libraries can be tested and used in the command line, iPython can perform better results than any other methods including compiled language systems.  Each function and each class can be tested online and instantly. We can feel the functions and the classes by the directly use in the command line. Our mind becomes to be emotionally familiar with generated codes. Our brains, also, will remembers each generated codes. Therefore, the probability to use the same codes later becomes much higher. Whenever command line interactive systems such as iPython are used, there are usually two problems. First, meaning function naming is not easy for each revised functions. Second, the number of the required input parameters for newly generated functions are too many, which results in not to be useful in command line keywords. Therefore, the i...

Advanced Prediction Method for Quantum Efficiency of OPV Devices

-
Advanced simulation for organic photo-voltaic (OPV) In order to predict the quantum efficiency of a organic photo-voltaic (OPV) devices, molecular-level modelling and simulation approach can be used.  The three computation parts are calculated to predict the quantum efficiency of organic photo-voltaic (OPV) devices. The morphology modelling part, exciton dissociation part and charge transport part are the three important parts to be modelled for performance evaluation.  We focus on a bulk hetero-junction (BHJ) OPV devices since it is known to achieve high quantum efficiency because of accelerating exciton dissociation efficiency.  Morphology modeling It has been known that the performance of organic material device is highly relied on morphology of organic material layers. In particular, the domain size and the percolation paths in morphology of active layers are critical factors to determine the performance of the organic photovoltaic device. Exciton dissociati...
