Short-range effect on C2, C3, C4 and C5 form factors in the ⁹⁰Zr atomic nucleus was scrutinized. The charge density of the ⁹⁰Zr was as well as scrutinized via the 1- and 2-body parts of cluster expansion in collaboration with harmonic functions of single particle. To incorporate the short-range effect in the 2-body part of cluster expansion, the Jastrow formula was used. Here, the core-polarization and model space participations are what lead to the form factors in ⁹⁰Zr. The transition density of core polarization was calculated using the Tassie form, relying on the charge density. The elements of one body density matrix were determined by performing shell model computations using the computer code OXBASH

A Weather Wireless Sensor Network (WWSN) has many limitations related to node throughput (NT), node power (P), and node energy (E). To address the limitations of WWSN, a mixed-byte LZW scheme is proposed. Mixed-Byte reduces the size of the sensed data by merging every two readings of data from the sensor into a single byte. The merged bytes would be highly frequent, which made them appropriate for compression by the Lempel Ziv Welsh (LZW) scheme. The result shows that the proposed Mixed-Byte-LZW gives the best compression ratio (CR) (0.01) for humidity and the best saving compressing rate (SR) (99%) for humidity and pressure. The simulated result shows that the Mixed-Byte-LZW scheme gives the best NT (580 Kbps) for humidity, the highest

This research proposed a 5.0 MW wind power project at the Al-Shihabi site in Iraq. The wind speed was collected from the Al-Shehabi metrological station at heights 10, 30, 50, and 52 m with 10-minute time intervals; then those data were compared with the hourly wind speed measured at 50 m for one year above the ground level obtained from the NASA site. The data were modeled using the Weibull distribution function for all wind power heights. Three methods were used to estimate Weibull parameters: Maximum Likelihood, Least Squares, and WAsP, which were executed to determine the numerical values of Weibull shape parameter (k), scale parameter (c), and mean wind speed. It is concluded that the annual mean wind speeds and the annual mean wind

Iron oxide (Fe₃O₄) nanoparticles were synthesized via an eco-friendly green approach by adding Phoenix dactylifera extract to the aqueous solution of ferric chloride. The effect of annealing temperature (Ta) (100-150) °C on particle size was studied. X-ray diffraction (XRD), UV-visible spectroscopy, atomic force microscopy (AFM), and field emission scanning electron microscopy (FESEM) were used to evaluate the produced nanoparticles. According to XRD spectra, the crystallite size of the samples was determined using the Scherrer formula. AFM and FE-SEM were used to determine surface morphology. A UV-Vis optical spectroscopic examination was carried out to determine the band gap energy of the iron oxide nano

The ecological interaction, human, geomorphological, and climatological factors lead to basin morphometry; morphometric aspects could be used as evidence for understanding the nature of these factors in terms of active dominant factors within the basin area. Quantitative morphometric analysis based on remote sensing imageries and GIS techniques is the best way to determine these aspects. In this research, a new approach was submitted: using Google Maps to track the Horan Valley path and region that passes through, delineating the main basins in the region, and then neglecting all basins that involve the valley only. The obtained results showed that the Horan region is a four-order basin with 213 1^st-order streams, 89 2^nd<

The digital image is considered one of the most heavily attacked and targeted data types because of its various applications and sensitive visual data. Many security techniques have been introduced to cover various image security needs, such as watermarking and steganography for intellectual property protection, authentication, and cryptography techniques for confidentiality and secrecy. In this paper, we present a technique that introduces enhancements to encryption quality and employs chaos theory to augment system robustness. The approach involves the generation of pseudo-random sequences through the utilization of the four-dimensional Lorenz system. These sequences serve a dual purpose: firstly, they facilitate image preprocessing by

Flavonoids, a wide range of phenolic compounds produced as secondary metabolites in plants, bacteria and fungi, have highly potent activities. In this study, the fungus  Gymnoascus dankaliensis was isolated in spring from sheep dung samples, and itsability to produce a secondary metabolite was investigated. The fungal secondary metabolite was extracted, and the antimicrobial and antioxidant activitis were tested. The results showed that Gymnoascusdankaliensis, thefirst ever isolated fungus from dung in Basrah, could produce a secondary metabolite that were produced using a Solid State Ferementation SSF medium after 40 days of incubation. The bioactive compounds were extracted from the solid media by using ethyl acetate

Stability in the atmosphere is the most important factor in the transport and dispersion of air pollutants. There are a number of complicated methods for determining stability. The majority of these methods are based on the amount of convective and mechanical turbulence in atmospheric motions, such as the Richardson number, Monin-Obukhov length, Pasquill-Gifford stability classification, and Pasquill-Turner stability classification. Pasquill utilized surface-accessible meteorological information like breeze speed, sun-based radiation, and surface darkness to portray air steadiness. Baghdad territory was separated into a gathering of focuses as indicated by scope and longitude; six focuses were chosen and conveyed in a manner that address

Predicting stock prices is a challenging task due to the numerous factors that impact them. The dataset used for analyzing stock prices often displays complex patterns and high volatility, making the generation of accurate predictions difficult. To address these challenges, this study proposes a hybrid prediction model that combines the salp-swarm algorithm and the artificial neural network (SSA-ANN). The SSA is used to optimize the weights and biases in the ANN, resulting in more reliable and accurate predictions. Before training, the dataset is normalized using the min-max normalization technique to reduce the influence of noise. The effectiveness of the SSA-ANN model is evaluated using the Yahoo stock price dataset. The results show t

We present in this paper the development and implementation of a new
steganographic method, the information will be hidden in the selected parts of the
table with floating-point numbers used as stego cover. The method is implemented
by transform each character in the text into numbers, then stores it as part of the
floating-point number. The main goal of steganography was fulfilled since the
resulted table did not drown any suspicion, the same table can be used by
experimental person for the different calculation.

Traffic collisions may happen in any location of the street for many reasons, careless drivers, narrow roads, badly designed intersections and traffic signals, are some of the reasons. When the collisions are repeated in a specific location, the case must be studied and solutions must be found to eliminate these collisions.
A GIS is a kind of super map, computer software that links geographic information (where things are) with descriptive information (what things are like). Unlike a flat paper map, where what you see is what you get, a GIS can have many layers of information underneath its surface.
In this paper GIS is used as a tool to examine, analyze, and suggest solutions for areas where traffic collisions have occurred in

In the current research work real time gamma correction (contrast balancing) procedure were performed. The motivation behind this research work is to reproduce an accurate image on the monitor for an uncorrected image on a particular computer system. But, in the real world, it isn't quite this simple, especially when an image needs to look good on different systems, or platforms because most computers, or more specifically, most computer systems, do not work in exactly the same way. However, the current work exploit the advantage that the most monitors work in about the same way with respect to gamma correction to reproduce correction image. Different images from real world were tested using current procedure to illustrate efficiency of

The research shows that the fractal structure of the speech signal exhibits
fractal characteristics. The encouraging analysis results indicated that the fractal
dimension have good discrimination capabilities for speech signal, where it gave
a speaker recognition percentage about 70% (In the field of research for a single
parameter this percentage be valued), and these capabilities are strongly depends
on the setting situations of the recording process. The pitch period is the another
used parameter supported to the fractal dimension to strengthen the verification
decision. Where the pitch period estimated by a new suggested simple method to
gave a speaker verification percentage about 90%. The coa

Two-dimensional computer simulations are carried out to quantify the quality of
apodized square aperture (ASA) in terms of the diffraction limited resolution and the
efficiency of detection of faint companions. The study involve the quality of the
point spread function (psf), and the modulation transfer function (MTF) of a
reference star. Annular apodized square aperture (AASA) is also considered in this
study. The results are then compared with the classical circular aperture.
ASA shows high contrast which increases the possibility of detection of faint
companions and AASA demonstrates significant high frequency components which
leads to high resolution.

In this research work a new fractal coding scheme based on IFS-transform for zero-mean range-domain blocks is investigated. Some improvements were performed on the IFS-matching stage, these improvements implies the use of moment indexing as a criteria to filter the domain blocks that suitable to match the range blocks, in addition to the use of stopping search condition based on the monitoring the minimum matching error, these additional coding steps will reduce the required long fractal coding time. The test results indicated that the proposed improvements had reduced the required coding time to more than 10 times without significant degradation in image quality (MSE or PSNR) level. Also the results indicated that the brightness preserv

The PCA is statistical technique that transforms a multivariate data set consisting of inter-correlated variables into a data set consisting of variables that are uncorrelated linear combination. In our project principal component analysis “PCA” was applied for two set of original bands in two dates (bands 1, 5, and 7 in 1988 and bands 1, 5, and 7 in 1990).
In this method the PCA of six channel data sets consisting of multi-temporal LANDSAT TM image pairs often generates higher order principal components that are related to the changes in brightness.
Although the image produced by the first component summarizes the information’s
that are common to all channels, we can see that the first principal component is

The problem of atmospheric turbulence has taken a considerable amount of attentions in the literatures. Most of theise studies have not considering the quantitative aspects of the seeing conditions in terms of mathematical representation.
The study involves two-dimensional computer simulations of short exposure recording using Kolmogorov approach. The quality of these images is quantified in order to see the effects of atmospheric turbulence on the observed images. This assessment shows clearly the parameters that affect the possibilities of approaching diffraction limiting resolution of the telescope.
The results demonstrate that the average frequency components are linearly proportional to the square of the telescope radius a

A two-dimensional model is constructed to simulate the flow regime of the
upper part of Dibdibba sandy aquifer in Safwan-Zubair area, south of Iraq. Although
the Dibdibba Formation is a multi-layer system in the surveyed area, the suggested
conceptual model which is advocated to simulate the flow regime of aquifer is fixed
for one layer, i.e., the activity of the deeper aquifer is negligible. The model is
calibrated using trial and error procedure in two stages: steady state followed by
transient state. The outcome of the calibration process demonstrated considerable
spatial variations in transmissivities and storativites of the aquifer system. A very
good similarity between the observed and simula

Let H and K be separable complex Hilbert spaces, and let B(H,K) be the space of bounded linear operators from H to K. If H=K we write B(H) for B(H,H).In this note we study separating vectors for separators on B(HK) that have representations of the form , where AB(H),BB(K) and CB(K,H).

The present paper deals with the study of petrophysical and dynamic properties of (207) plugs which were taken from rock cores of Khasib Formation at five oil wells (No.2, AM-1 AM-2, HF-3, and HU-1) located in Missan area, South of Iraq.
A comparison was made for the studied properties deduced from laboratory and from the available well logs. (35) predictive equations are established to estimate the effective porosity, permeability, in terms of the properties that are obtained from resistivity sonic, radioactivity and neutron porosity logs. These equations showed that multiple correlation coefficients (R) have ranged between weak and excellent. Statistical relations regarding the calculated and the observed values of these propertie

Yoshida and Adachi’s diploid genetic algorithm- the so-called pseudo-Meiosis genetic Algorithm (psM GA)- was focused on preserving population diversity and adapting the population quickly to problem changes. The large population diversity provided by psM GA with good adaptation to the problem changes were effective and sufficient to tackle non-stationary traveling salesman problem. They did not apply this genetic algorithm to other problem domains, like bit-coding problems. Hence, in this paper we revisit the psM GA, apply it on bit-coding problems so as to see the effect and search power of this genetic search algorithm on this problem domain.
