Neonatal diarrhea of calves is a major cause of economic loss in rearing young
calves. Buxtonella sulcata may be a potential cause of diarrhea in these animals
.This study aimed to investigate the prevalence of B. sulcata infection and its role in
diarrhea in neonatal and young calves. A total of 250 fecal samples were collected
from calves (110 male and 140 female, ages ranged 1-30 day, among which 98 had
diarrhea). Two laboratory tests were used to detect B. sulcata cysts and trophozoites
in fecal samples which are direct wet film method and ether-formalin sedimentation
method. The overall rate of infection was 43.2%. There is a significant difference in
the rate and intensity of infection betwee

applications. Tracking of object type is a matching trouble. In object tracking, one
main difficulty is to select features and build models which are convenient for
distinguishing and tracing the target. The suggested system for continuous features
descriptor and matching in video has three steps. Firstly, apply wavelet transform on
image using Haar filter. Secondly interest points were detected from wavelet image
using features from accelerated segment test (FAST) corner detection. Thirdly those
points were descripted using Speeded Up Robust Features (SURF). The algorithm
of Speeded Up Robust Features (SURF) has been employed and impl
Clustering algorithms have recently gained attention in the related literature since
they can help current intrusion detection systems in several aspects. This paper
proposes genetic algorithm (GA) based clustering, serving to distinguish patterns
incoming from network traffic packets into normal and attack. Two GA based
clustering models for solving intrusion detection problem are introduced. The first
model coined as handles numeric features of the network packet, whereas
the second one coined as concerns all features of the network packet.
Moreover, a new mutation operator directed for binary and symbolic features is
proposed. The basic concept of proposed mutation operator depends on the most
frequent value
In recent years, the iris biometric occupies a wide interesting when talking about
biometric based systems, because it is one of the most accurate biometrics to prove
users identities, thus it is providing high security for concerned systems. This
research article is showing up an efficient method to detect the outer boundary of
the iris, using a new form of leading edge detection technique. This technique is
very useful to isolate two regions that have convergent intensity levels in gray scale
images, which represents the main issue of iris isolation, because it is difficult to
find the border that can separate between the lighter gray background (sclera) and
light gray foreground (iris texture). The proposed met

One of the most advance technologies to do so is the use of advanced texturing for the front surface of the cells. This texture, also known as Black Silicon, consists of peaks and valleys of nano metric dimensions and capable of dramatically reducing the reflectance of the front surface. A reflectance around 5% was reached ,using simulation, when using a Black-Silicon texturing with height of 50nm with peak rounding of 5nm. Even though this texturing may affect other parameters such as series resistance or surface recombination, as a starting point

A design and implementation of images' cryptography system is evaluated in this
paper. This system depends on the idea of allocating a part of a digital image
(possibly the first block of the image) so as to produce the cipher keys for the other
parts. Circles generating algorithm is used to produce keys from the chosen block,
then corresponding circles in other blocks will be encrypted using the located keys.
So in this method encryption keys are brought from the plain-image (source image)

In this paper a simulation for a mathematical two dimensional model was conducted
to assess the presence of defocusing due to telescope aperture quality. The point
spread function (psf), Modulation transfer function (MTF), and Fourier frequencies
of binary star are computed in the absence and presence of defocusing. The results
show that the total frequency components of MTF decreases very sharply as
defocusing values goes to 6 and after this value the total frequency changes very
slightly afterward. The relative heights of the second to third peaks decrease rapidly
as defocusing values goes to 3 and slightly changes after that.
The effect of pressure, applied to PMMA sample, on Mach -Zender interference
pattern has been studied.
The effects of length, depth and height of the PMMA samples on the resulting
number of fringes are investigated. The results of the experiments show almost a
linear behavior between the numbers of displaced fringes and the displacement of
the PMMA molecules with the applied pressure in all cases.
Finally, comparing the experimental with the theoretical results, it is found that,
there is a good agreement, in most cases, between them provided introducing a
correction factor which is found to be equal approximately 3.This effect can be used
as a pressure sensor.

The preequilibrium statistical model, which is used to analyze nuclear reaction data, depends basically on number of parameters including the master equation. A numerical solution for the master equation of the preequilibrium statistical model is presented in this work. One-component Fermi gas model is assumed. This numerical method is shown to give the same accuracy for the simple as well as the more advanced schemes. The present method shows fast convergence for a wide range of physical system parameters. Such a method is applied for two reaction examples that include neutron and proton induced reactions with 54Fe nucleus for entrance energies 20 and 80 MeV.
