Regarding low fertilization rate of Barbus sharpeyi, one of the main Barbus species in south of Iran, saline activator solutions (SAS 1 and 2) were used for increasing of sperm activation and its sperm quality indices were assessed by using Image J software as a fish sperm adapted tools. SAS 1 (45mM NaCl, 5mM KCl, 30mM Tris, 188±2.3 mosmol/kg) and SAS 2 (50mM NaCl, 30mM KCl, 30mM Tris, 189±1.7 ...

This paper describes tools for the theoretical and experimental study of several DPCM methods in image acquisition and compression, with applications in Intelligent Visual Sensor development. The paper also presents conclusions about DSP based implementations of the described algorithms. 1.Introduction DPCM ([1][2]) is a general method of compression useful in various fields of the signal proce...

• Apply derivative-of-Gaussian filters ∇σ. •Represent local image structure by 2 × 2 matrix S(x, y) = ∇σI ( ∇σI )>. • S(x, y) is smoothed at scale τ . The response C(x, y) = detSτ / trSτ has maxima at distinctive image-points (qx, qy). •Consider the colour of I` around q i `, vs. the colour of Ir around q j r . •Difference between the two colours is put into a matching-table, fij. •Compute the ...

Image analysis and recognition on a journal or conference paper, called J-image here, is greatly worthy of researching due to existence of various objects and layouts in it. Furthermore, a scanned J-image may be not in a normal orientation, which will usually affect the recognition result. Thus solving the document skew problem is still a challenging topic today. In this paper, a contour analys...

By a classical theorem of Harvey Friedman (1973), every countable nonstandard model $\mathcal{M}$ sufficiently strong fragment ZF has proper rank-initial self-embedding $j$, i.e., $j$ is such that $j[\mathcal{M}]\subsetneq\mathcal{M}$, and the ordinal rank each member $j[\mathcal{M}]$ less than element $\mathcal{M}\setminus j[\mathcal{M}]$. Here we investigate larger family initial-embeddings m...

A previous experimental evaluation’ of nine commercial gamma-ray spectroscopy systems demonstrated significant benefits of digital signal processing for improvements in the performance of high-resolution gamma-ray spectroscopy systems. Spectacular improvements in the energy resolution and throughput of germanium detectors were demonstrated for the DSPEC. Recently, a new, improved version of DSP...

We report the discovery of a new gravitational lens candidate Q2138-431AB, comprising two quasar images at a redshift of 1.641 separated by 4.5 arcsecs. The spectra of the two images are very similar, and the redshifts agree to better than 115 km.sec. The two images have magnitudes BJ = 19.8 and BJ = 21.0, and in spite of a deep search and image subtraction procedure, no lensing galaxy has been...

The recently discovered coexistence of incommensurate antiferromagnetic neutron scattering peaks and commensurate resonance in underdoped YBa2Cu3O6+x is calling for an explanation. Within the t-J model, the doping and energy dependence of the spin dynamics of the underdoped bilayer cuprates in the normal state is studied based on the fermion-spin theory by considering the bilayer interactions. ...
