Making a note for each digital photo one by one is not efficient when the photo collection is thousands of units. Therefore, users will want an efficient approach to retrieve photos based on metadata of their digital photos. So, annotation process would play a vital role in the retrieval process. In this paper, we describe our growing work on a group of photo annotations for personal digital ph...

Abstract: (Y2O3) and ethyl acetate as a mineralizer by hydrothermal method at a low temperature (T=.230°C, andP=100bars).The as-prepared powders were characterized by X-ray Diffraction (XRD), Fourier Transform InfraredSpectroscopy (FTIR), Scanning Electron Microscopy (SEM), UV-V Spectroscopy and Chemical Oxygen Demand(COD) of the sewage water, respectively. The results show that hydrothermal me...

Fermion compositeness and other new physics can be signalled by the presence of a strong four-fermion contact interaction. Here we present a study of llqq and llll contact interactions using the reactions: ll → ll, bb̄, cc̄ at future ee linear colliders with √s = 0.5− 5 TeV and μμ colliders with √ s = 0.5, 4 TeV. We find that very large compositeness scales can be probed at these machines and tha...

zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...

tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. photo degradation of congo red (azo dye) showed that photo catalytic property of the as-prepared wo3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. photo degradation of rhodamine b (cationic triary...
