the decomposition of feedstock and formation of

solid carbon is the dominant process and has an important role in the

production of carbon black. The comparison of calculated results

against the experimental measurements shows good agreement...

A new acceleration technique is presented for shooting and bouncing ray tracing in indoor environments. Tracing just a few rays, the algorithm finds the solid angles around the transmitter that transport electromagnetic ...

A novel blind watermarking technique based on QR decomposition in still images is proposed. The method is implemented in wavelet domain and its robustness has been evaluated against some image processing attacks and the results have been compared...
