DCT IMAGE COMPRESSION USING SLIDING RLETECHNIQUE
...Show More Authors

The discrete cosine transform (DCT) is a method for converting a signal into
plain frequency components. It is extensively used in image compression. In this
paper a new technique is proposed, namely SRLE (Sliding Run Length Encoding)
which is based on a lossy compression, and used to enhance image data
compression.
Image quality is measured impartially, using peak signal-to-noise ratio (PSNR) or
picture quality scale, and individually using perceived image quality with
compression factor (CF) being the main theme of this paper, taking into
consideration the preservation of well PSNR outputs.
The performance of DCT compression generally degrades low bit-rates mainly
because of the underly

Uncertainty Analysis to Assess Depth Conversion Accuracy: A Case Study of Subba Oilfield, Southern Iraq
...Show More Authors

    The depth conversion process is a significant task in seismic interpretation to establish the link between the seismic data in the time domain and the drilled wells in the depth domain. To promote the exploration and development of the Subba oilfield, more accurate depth conversion is required. In this paper, three approaches of depth conversions: Models 1, 2, and 3 are applied from the simplest to the most complex on Nahr Umr Reservoir in Suba oilfield. This is to obtain the best approach, giving less mistakes with the actual depth at well locations and good inter/extrapolation between or away from well controls. The results of these approaches, together with the uncertainty analysis provide a reliable velocity model

INTRUSION DETECTION USING A MIXED FEATURES FUZZY CLUSTERING ALGORITHM
...Show More Authors

Proliferation of network systems and growing usage of Internet make network
security issue to be more important. Intrusion detection is an important factor in keeping
network secure. The main aim of intrusion detection is to classify behavior of a system
into normal and intrusive behaviors. However, the normal and the attack behaviors in
networks are hard to predict as the boundaries between them cannot be well distinct.
This paper presents an algorithm for intrusion detection that combines both fuzzy C
Means (FCM) and FCM for symbolic features algorithms in one. Experimental results
on the Knowledge Discovery and Data Mining Cup 1999 (KDD cup 99) intrusion

Serum Level of Interleukin-35 in Patients with Chronic Hepatitis B Virus Infection
...Show More Authors

Interleukin-35 (IL-35) is a new member of IL-12 family of cytokines, and its role in pathogenesis of hepatitis B virus (HBV) infection has been recently suggested. Accordingly, a case-control study was conducted during June - October 2018 to determine IL-35 serum level in Iraqi patients with chronic HBV infection. The results revealed that IL-35 level was significantly decreased in patients as compared to control (163 vs. 301 pg/ml; p < 0.001). However, such decreased level was more pronounced in patients at the age groups < 40 and 40 – 50 years (165 and 145 pg/ml, respectively) as compared to the corresponding age groups in control (482 and 234 pg/ml, respectively).

     The time fractional order differential equations are fundamental tools that are used for modeling neuronal dynamics. These equations are obtained by substituting the time derivative of order  where , in the standard equation with the Caputo fractional formula. In this paper, two implicit difference schemes: the linearly Euler implicit and the Crank-Nicolson (CN) finite difference schemes, are employed in solving a one-dimensional time-fractional semilinear equation with Dirichlet boundary conditions. Moreover, the consistency, stability and convergence of the proposed schemes are investigated. We prove that the IEM is unconditionally stable, while CNM is conditionally stable. Furthermore, a comparative study between these two s
