In this paper, we propose a high speed CAVLC (Context-based Adaptive Variable Length Coding) decoder for H.264/AVC. The previous hardware architectures perform five steps in series to obtain the syntax elements to restore the residual and the codeword length to get next input bitstream (we call it 'valid bits'). Since several cycles are required for the(More)
Atmospheric aerosols and their effect on clouds are thought to be important for anthropogenic radiative forcing of the climate, yet remain poorly understood. Globally, around half of cloud condensation nuclei originate from nucleation of atmospheric vapours. It is thought that sulfuric acid is essential to initiate most particle formation in the atmosphere,(More)
Data aggregation has been one of important key techniques to increase energy efficiency and bandwidth utilization in wireless sensor networks. There were many research works in this area, but most of them have a disadvantage that cannot optimally meet practical requirements, such as the heterogeneity of application data and latency requirements. In this(More)
About half of present-day cloud condensation nuclei originate from atmospheric nucleation, frequently appearing as a burst of new particles near midday. Atmospheric observations show that the growth rate of new particles often accelerates when the diameter of the particles is between one and ten nanometres. In this critical size range, new particles are(More)
We investigated the nucleation of sulfuric acid together with two bases (ammonia and dimethylamine), at the CLOUD chamber at CERN. The chemical composition of positive, negative, and neutral clusters was studied using three Atmospheric Pressure interface-Time Of Flight (APi-TOF) mass spectrometers: two were operated in positive and negative mode to detect(More)
