Photonic crystal waveguide slow-light grating emits a free-space optical beam and steers it widely by changing the wavelength or refractive index. In reverse process, returned light is coupled into device again. We have proposed to use this transmission reception antenna as scanner for detection ranging (LiDAR). Ideally, large-aperture can narrow enhance efficiency. Actually, however, performan...

Light intensity intercepted by the soybean canopy during the reproductive period is an important environmental factor determining soybean yield components and grain yield. A 2-year field experiment was conducted to investigate the effects of light enrichment and its interaction with planting density on yield formation of soybean cultivars. Light enrichment increased seed yield per plant and yie...

Economic growth and its demographic benefits have enhanced the high rate of urbanization in Indonesia, although property tax revenues are still low compared to G20 countries. This performance is partly due limited capacity local governments, regarding determination building values for calculations. To improve government performance, LIDAR mapping capable being used quickly estimating price a bu...

the present study has tried to accomplish an analysis of margaret atwood’s novels oryx and crake, and the year of the flood in the light of posthuman and cyborg theories. considering posthumanism as a critical reading of some notions of humanism focus of which in this thesis has been identity, new definitions for humanity and human identity are formed. haraway’s cyborg, as one possible new figu...

Light detection and ranging (LIDAR) systems are finding their way into an increasing number of applications including autonomous vehicles. Image sensors based on single-photon avalanche diode (SPAD) arrays have demonstrated great promise for LIDAR, typically using flood illumination or raster-scanning a small spot. Holographic illumination, phase-only liquid crystal silicon (LCoS) spatial light...
