Light emitting display and driving method thereof

Abstract: A light emitting display including data lines for applying data voltages corresponding to video signals, scan lines for transmitting select signals, and pixel circuits. Each pixel circuit includes a light emitting element for emitting light, and a transistor including first to third electrodes, for controlling a current output to the third electrode according to a voltage between the first and second electrodes. Each pixel circuit also includes a first switch for diode-connecting the transistor, a capacitor having a first electrode coupled to the first electrode of the transistor, a second switch for applying a corresponding said data voltage to the second electrode of the capacitor in response to a corresponding said select signal from a corresponding said scan line, and a third switch for substantially electrically decoupling the second electrode of the capacitor from a power supply voltage source.

Optimal operational factors for nitrite accumulation in batch reactors.

Abstract: The environmental factors that affected the accumulation of nitrite in nitrifying reactors were investigated using a mixed culture A batch reactor with 50 mg-N/l of ammonia was used The pH, temperature and dissolved oxygen concentration were varied The concentration of unionized free ammonia also changed with the oxidation of ammonia and the variation of pH and temperature The accumulation of nitrite was affected sensitively by pH and temperature A higher nitrite concentration was observed at pH 8-9 or temperature around 30 °C The dissolved oxygen also affected, giving the highest nitrite accumulation at around 15 mg/l These were the favoredconditions for nitrite production The free ammonia concentration influenced thenitrite accumulation also, by inhibiting nitrite oxidation The inhibition becameapparent at a concentration of approximately 4 mg/l or above, but insignificant atbelow 1 mg/l Thus, simultaneously high free ammonia concentration and maximumspecific ammonia-oxidation rate (above 15 × 10-3 mg-N/mg-VSSċh)were needed for a significant nitrite accumulation When the two conditions were met, thenthe highest accumulation was observed when the ratio of the maximum specific oxidationrate of ammonia to the maximum specific oxidation rate of nitrite (ka/kn) was highestUnder the optimal operating conditions of pH 8, 30 °C and 15 mg/l of dissolvedoxygen, as much as 77% of the removed ammonia accumulated in nitrite

VPGNet: Vanishing Point Guided Network for Lane and Road Marking Detection and Recognition

Abstract: In this paper, we propose a unified end-to-end trainable multi-task network that jointly handles lane and road marking detection and recognition that is guided by a vanishing point under adverse weather conditions We tackle rainy and low illumination conditions, which have not been extensively studied until now due to clear challenges For example, images taken under rainy days are subject to low illumination, while wet roads cause light reflection and distort the appearance of lane and road markings At night, color distortion occurs under limited illumination As a result, no benchmark dataset exists and only a few developed algorithms work under poor weather conditions To address this shortcoming, we build up a lane and road marking benchmark which consists of about 20,000 images with 17 lane and road marking classes under four different scenarios: no rain, rain, heavy rain, and night We train and evaluate several versions of the proposed multi-task network and validate the importance of each task The resulting approach, VPGNet, can detect and classify lanes and road markings, and predict a vanishing point with a single forward pass Experimental results show that our approach achieves high accuracy and robustness under various conditions in real-time (20 fps) The benchmark and the VPGNet model will be publicly available
