The objective of image compression is to reduce irrelevance and redundancy of the image data in order to be able to store or transmit data in an efficient form. There are so many problems in the digital grayscale encrypted image transferring over the internet, such as security level of encrypted image, the speed of internet, time of encrypted image transferring and so on. One of these problems is the insufficient of internet bandwidth that the encrypted image will transferred through it, so to solve the problem of insufficiently of internet bandwidth, the grayscale image will compressed by using quadtree fractal compression method before encrypting this image and transferring it via internet. Quadtree fractal compression method has advantage of high compression ratio but also has disadvantage with a long time of compression process which it effected on the decompressed image quality. In this thesis, we focused on quality problem of deco...

The flock demonstrated characteristic clinical signs, post mortem lesions and was positive to IBV and NDV by RT-PCR. The (S1) spike glycoprotein gene of (IBV) isolate was partially amplified by RT-PCR, then directly sequenced. The virus was designated (IBV/chicken/Egypt/VRLCU154/2012). Blast analysis, multiple alignments and phylogenetic analysis revealed that IBV isolate was in close relation to the IBV isolate IS/1494/06 (EU780077.2) with high nucleotide homology (97%). The sequence was submitted to NCBI GenBank with the accession No.JX893950. The results of the present study indicate that IS/1494 like strains might have a similar origin based on the genetic relationship among variants and reference strains.

Additionally, the passive layer germination behavior on aluminum alloy 1050 with anticorrosive properties. The passive layer is an alloying method which allows an aluminum oxide to germinate. Morphologically and structurally, the aluminum oxide films were characterized using microscopy analyzes and XRD analysis. Results indicated that the reinforcements are well distributed and the grin size is downy. Corrosion behavior tested by Cyclic polarization exam and done at room temperature in (3.5 per cent NaCl) solution. The reinforcement increased the hardness for processed aluminum from Hv81.1 to HV=120.492 as castings. The parameter Nano-MetalPhosphate has attenuated the current density of corrosion (7.15μA / cm2) compared to the as-cast sample results.

The points are typically acquired with multiple range scans of any 3D object. The proposed algorithm follows the advancing front paradigm to build the reconstructed surface employing a variable radius moving ball that expands and shrinks continuously based on the sampling density. Starting with a user-specified initial radius, this initial ball may touch three points without containing any other point forming a seed triangle. For any edge, another point is found to form a ball with minimum radius generating another triangle. The process continues until generating all possible edges. The algorithm is theoretically proved under certain sampling criteria on the input data set. The proposed algorithm was applied on different datasets and compared favorably with the most eminent techniques. The key issues for comparisons were the reconstructed surface quality, the memory usage and the execution time. The present algorithm bested others in treating non uniform samples, samples with sharp edges and samples with small holes
