Extremism Detection in the Iraqi Dialect Based on Machine Learning
...Show More Authors

Extremism detection is an important area of natural language processing (NLP). It is used to detect hate speech, sectarianism, and terrorism on social media. This field has been discussed and studied in many international languages, especially Arabic and English, as many studies touched on languages in particular, but dialects were not addressed even though users of social networking sites write in their dialect. One of the most difficult Arabic dialects is the Iraqi dialect. Because the Iraqi dialect has few sources on the Internet regarding available data that can be used by researchers, this research aims to detect extremism in Iraqi texts using machine learning. The data was pre-processed by deleting suffixes and prefixes for Iraqi w

Oscillation and Convergence of Solutions of Second Order Neutral Differential Equations with Periodic Coefficients
...Show More Authors

This research aims to study the behavior of solutions of second-order neutral differential equations with periodic coefficients. Some necessary and sufficient conditions have been obtained that classify all solutions of these equations into three categories: either oscillatory, non-oscillatory, and convergent to zero, or non-oscillatory and divergent. The extent to which periodic coefficients influence the occurrence of oscillation, convergence, or divergence for each solution has been explained. The equation under consideration contained a variable delay and a constant delays in which the coefficients are periodic. Not much previous research has discussed the oscillation of solutions of second-order neutral equations with periodic coeff

Investigating Rijndael-Based Algorithms for Audio Ciphering
...Show More Authors

Voice encryption is crucial to protecting data during transmission and storage due to the widespread problem of document fabrication and forgery. Various methods have been used to protect important data, including encryption. Voice data encryption is a way to encrypt important messages within transmissions. Therefore, it needs a strong and efficient encryption algorithm, using the standard encryption algorithm known as Rijndeal. This method is reliable, secure and efficient, because the Rijndael algorithm is characterized by its key lengths and blocks of different sizes. The Rijndael algorithm is a method of decrypting audio files, making it a powerful tool for protecting sensitive information. This paper presents a method for encoding W

Mathematics and the applied sciences both heavily rely on fixed point ( theory. Additionally, this theory has several applications in integral equations and differential equations to guarantee the solutions' existence and uniqueness.  theory relies mainly on the Banach contraction principle. Since this idea first appeared, it has gained a lot of attention and there has been a lot of development in this field. In this paper, the concept of generalized Kannan-type() mapping is presented in intuitionistic fuzzy metric space(IFM space), and the  theory is proven. The results contain extensions of  theory in IFM-space which include the Caccioppoli  theorem. Additionally, an  instance is provided to illustrate the practi

A Hybrid Method for Speech Noise Reduction Using Log-MMSE
...Show More Authors

Noise reduction is a significant field that appears in many aspects of life. There are many methods for speech noise reduction, especially for stationary noise. This paper talks about a new way to lower speech noise that combines the Log-MMSE (Logarithmic Minimum Mean Square Error) algorithm, which is used to improve speech signals that have been messed up by noise, with an adaptive Wiener filter with a decision-directed (DD) approach. This filter lowers musical noise and predicts the time-varying noise spectrum, which results in a better signal-to-noise ratio. The frame delay issue resulting from DD was resolved by utilizing the Two-Step Noise Reduction (TSNR) technique to reconstruct the harmonic structure of the voice signal that was

Fractional Free Volume Dependence of Neutron-IrradiatedPolystyrene (PS) Measured by Positron Method
...Show More Authors

The fractional free volume (Fh) in polystyrene (PS) as a function of neutron-irradiation dose has been measured, using positron annihilation lifetime (PAL) method. The results show that Fh values decreased with increasing n-irradiation dose up to a total dose of 501.03x 10-2 Gy.
A percentage reduction of 2.14 in Fh values is noticed after the initial n-dose corresponding to a percentage reduction of 42.14/Gy. The total n-dose induces a percentage reduction of 7.26, corresponding to a percentage reduction of 1.45 per Gy. These results indicate that cross -linking is the predominant process induced by n-irradiation.
The results suggest that n-irradiation induces structure changes in PS, causing cross-linking in PS chains, whereas

The s-level of a screened hydogenic atom in a uniform magnetic field of arbitrary strength B have been calculated accurately. First, the related spherical symmetric case )~(2122Brhas been treated by using the linear variational method. The trial wave function is taken as linear mixture of hydogenic and 3D harmonic ascillator wave functions of s-symmetry. Second, the actual nonspherical case)(21222yx is studied by adopting the correction proposed by Mustafa and Chhajlany (Phys. Rev.A,50,(I994),2926). The latter accounts for the difference between the two cases in an appaximate way by utilizing the properties of the 2D and 3D harmonic oscillators.

This paper focuses on trading a few least significant bits of original floating-point values and replacing them with a secret text. A secret text is implemented by transform each character in the text into numbers (using RSA algorithm), then stores it as part of floating-point numbers embedded with plain drawing. The main goal of steganography was fulfilled since changing plain drawing did not drown any suspicion; the same drawing can be used by experimental person and does not alter the original data content.
