A Universal Compression scheme is presented, to compress sequences of quantum information from unknown quantum sources (i.e. described by unknown density matrix ρ) asymptotically to S(ρ), with fidelity bounded toward unity. The introduction of a“B-diagonalisation” process allows us to treat the input as if it were diagonal in a known basis B. Applying a version of the Lempel-Ziv algorithm in th...

from the time that civil engineers have used steel in building structures, they tried to increase its strength so as to produce more economic and lighter structures by using more elegant sections. increase of steel strength is not always useful for all members of a steel structure. in some members under certain conditions, it is needed to reduce the strength as much as possible to improve the b...

The paper introduces the idea of non-uniform quantization in the detail components of wavelet transformed image. It argues that most of the coefficients of horizontal, vertical and diagonal components lie near to zeros and the coefficients representing large differences are few at the extreme ends of histogram. Therefore, this paper advocates need for variable step size quantization scheme whic...

Figure 1 – Panel A, extrinsic compression of the diagonal branch and septal branches (white arrows). Panel B, ventriculography of the right ventricle (RV) and left ventricle (LV), showing significant interventricular septal (IVS) hypertrophy during diastole and Panel C, LV outflow tract obstruction during end-systole. A 35-year-old man sought medical care for recurrent syncope episodes related ...

The demonstration not only showed the two current HDTV formats, 720p/50 and 1080i/25, but also introduced the next-generation HDTV format – 1080p/50. All three formats were presented with identical content and simultaneously on three Full-HD displays, in uncompressed and compressed form. Thus, viewers of the demonstration were able to judge the HDTV image quality for themselves. The overall goa...
