Text-based Steganography using Huffman Compression and AES Encryption Algorithm

In every system of security, to keep important data confidential, we need a high degree of protection. Steganography can be defined as a way of sending confidential texts through a secure medium of communications as well as protecting the information during the process of transmission. Steganography is a technology that is used to protect users' security and privacy. Communication is majorly achieved using a network through SMS, e-mail, and so on. The presented work suggested a technology of text hiding for protecting secret texts with Unicode characters. The similarities of glyphs  provided invisibility and increased the hiding capacity. In conclusion, the proposed method succeeded in securing confidential data and achieving high payload capacity by using the Huffman compression algorithm, which was implemented on an unlimited text length. In addition, this approach has the ability to hide a single bit in every digit or letter in the cover file. Also, the approach meets the cognitive transparency and does not make the modifications apparent on the original data. The method suggested in this work increases the security level through coding a secret message before embedding it within the cover text, with the use of the Advanced Encryption Standard (AES) algorithm.

The philosophy of physical and sensory communication in the dramatic show

Modern critical theories revealed polemical views about the reality of the existence of communication - as a necessity for building a deliberative discourse - in the theater or not. To the theory of communication with all the conditions it imposes on thinking, interaction, and emancipation of selves in different contexts.
Therefore, the current research included four chapters, the first chapter dealt with the research problem, which was represented in (the philosophy of sensory and physical communication in theatrical performance), and the first chapter included the importance of the research, its goal and its limits, and ended with defining the terminology, and the second chapter included (theoretical framework) the first topic (ph

Correlation between some immunological parameters and clinical presentation in RA patients

Background: Complement (C) & CRP in patients with Rheumatoid arthritis (RA)'could be trigger disease activity.
Aim: To study the correlation between C, CRP, IgM,, IgG, IgA & some clinical presentation in RA patients.
Methods: Latex agglutination test(AG) & single radial immunoassay(SRIA) were used to asses CRP, IgMJgGJgA,, C, in 74 patients with RA.
Results: IgA & IgG were significantly increased, while the mean ofC3, C4 were slightly elevated in RA patients .
Conclusion: There is correlation between IgG and IgM with joint deformity and joint swelling respectively, while C3 was showed statistically significant P<0.01 with joint
stiffness, joint swelling and Rheumatoid nodule, whe

Public Procurement Crisis of Iraq and its Impact on Construction Projects

 

The public procurement crisis in Iraq plays a fundamental role in the delay in the implementation of construction projects at different stages of project bidding (pre, during, and after). The procurement system of any country plays an important role in economic growth and revival. The paper aims to use the fuzzy logic inference model to predict the impact of the public procurement crisis (relative importance index and Likert scale) was carried out at the beginning to determine the most important parameters that affect construction projects, the fuzzy analytical hierarchy process (FAHP) to set up, and finally, the fuzzy decision maker's (FDM) verification of the parameter for comparison with reality. Sixty-five

Serum Gamma GlutamylTransferase, Amylase and Alkaline Phosphatase activities in kidney diseases.

Background: The study enrolled a total of 78 patients with acute and chronic kidney diseases for evaluation of the activity of enzymes, gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP) and amylase and compared with 42 normal healthy groups with normal albumin, creatinine and other kidney functions test and the samples were obtained from different hospitals in Baghdad.
Patients and methods: Three groups of patients were included. The first group consists of 15 patients with acute kidney diseases that occurs over days to weeks in which measurement of GGT, ALP and amylase were performed. Second group consists of 38 patients suffering from acute kidney diseases for 2-3 months in which serum GGT was

Groundwater Simulation and Wells Distribution at Qazaniyah City in Diyala Governorate

In recent years, there is more interest in water sources availability, including groundwater due to an increase in demand for water because of the increasing population in the world, and the water recedes due to climate change also. Therefore, the study of groundwater has required more attention. The aim of the present study is to establish a MODFLOW model in the groundwater modeling system software to simulate the movement of groundwater in the Turssaq alluvial fan which is located in the Qazaniyah city, east of Diyala Governorate. The solid model was used to define the aquifer in the study area. Using the GIS software, mapping and preparing the data needed to create a conceptual model were carried out. The data of the

Mathematical Model of Amplified Stimulated Raman Scattering and Fiber Raman Amplifier

The result of a developed mathematical model for predicting the design
parameters of the fiber Raman amplifier (FRA) are demonstrated. The amplification
parameters are tested at different pump power with different fiber length. Recently,
the FRA employed in optical communication system to increase the repeater distance
as will as the capacity of the communication systems. The output results show, that
high Raman gain can be achieved by high pumping power, long effective area that
need to be small for high Raman gain. High-stimulated Raman gain coefficient is
recommended for high Raman amplifier gain, the low attenuation of the pump and the
transmitted signal in the fiber lead to high Raman gain.

Assessment of microvessels density and inflammatory status in oral lichen planus

Background: Oral lichen planus (OLP) is a chronic inflammatory disease with an autoimmune inflammatory pathogenesis. The purpose of this study was to evaluate the role of angiogenesis in the pathogenesis of OLP, using CD34 stain to highlight the blood vessels for measuring the microvessel density (MVD) as well as to evaluate the relation of this marker with the degree of inflammation Materials and Methods: Immunohistochemical (IHC) staining technique was used to evaluate angiogenesis using CD34 in 46 paraffin blocks 10 of them obtained from normal mucosa and 36 from cases diagnosed as lichen planus , 20 of them diagnosed as Reticular type while 16 as erosive type. Severity of inflammation was divided into mild, moderate and severe accordi

The reality of child labor in Baghdad ... And access to treatment

  The phenomenon of child labor, any activity performed by a child and represents a contribution to the production, this phenomenon had been rife in Iraqi society, after that the proportion of child labor for the age group (6-14 years) amounting to 3% in 2006, became for  the same age group of 8% in 2008*.                                                      

It is recognized that each phenomenon reasons, the phenomenon which our atten

On Faintly θ- Semi-Continuous and Faintly δ-Semi-Continuous Functions

      Faintly continuous (FC) functions, entitled faintly S-continuous and faintly δS-continuous functions have been introduced and investigated via a -open and -open sets. Several characterizations and properties of faintly S-continuous and faintly -Continuous functions were obtained. In addition, relationships between faintly s- Continuous and faintly S-continuous function and other forms of FC function were investigated. Also, it is shown that every faintly  S-continuous is weakly S-continuous. The Convers is shown to be satisfied only if the co-domain of the function is almost regular.
