The stress and drag at the surface of ocean are crucial parameters for both short term forecasting modeling long‐term global climate trends. However, partition between viscous, turbulent, wave stresses, in particular effects airflow separation not well understood. We present direct measurements velocity above wind‐generated waves. observe intermittent viscous sublayer past crest wind waves leading to dramatic along‐wave variability tangential stress. These results hold speeds that would...

Image Mosaicing algorithm based on random corner method is proposed. An image mosaic a of assembling multiple overlapping images same scene into larger one. The output will be the union two input images. In this paper we have to use three step automatic methods. first taking and finding out corners in both images, second removing false then by using homography find its matched pair get final mosaic. experimental results show proposed produces an improvement accuracy, efficiency robustness.
In this paper, we discuss the real time implementation of adaptive noise cancellation based on an improved Wiener filter Texas Instruments TMS320C6713 DSK. Its performance is compared with Leepsilas filter. LabVIEW models are illustrated for using National TI DSP test integration toolkit and filters toolkit. These tested noisy wavelet data sets speech/wave files. Furthermore, a model design LMS Simulink implemented C6713. The profile statistics auto-code generated by Real Time Workshop...
Square microhotplates find their usefulness because of ease fabrication and high yield compared with bridge or spider membrane. It has been already established that often in microhotplates, an insulation layer is required to separate the thermal domain from other application domains such as gas sensor. However, enhancing performance microhotplate by optimization area, especially terms power uniformity aspects, not explored yet. Nevertheless, improvement was also accompanied increased...
