Improving Error Correction Stage And Expanding The Final Key Using Dynamic Linear-Feedback Shift Register In Sarg04 Protoco, Omer Sherko Mustafa, Ali Hussein Yousif, Dana F. Abdulqadir Apr 2019

Improving Error Correction Stage And Expanding The Final Key Using Dynamic Linear-Feedback Shift Register In Sarg04 Protoco, Omer Sherko Mustafa, Ali Hussein Yousif, Dana F. Abdulqadir

Polytechnic Journal

The mechanism of quantum mechanics is considered as the principal method of quantum key distribution for transmitting a cryptographic key between users in unconditionally secure communication. In this paper, simulation and enhancement of the performance of SARG04 protocol have been done in terms of error correction stage using multiparity rather than single parity. In addition, the suitable length of subblock was selected depending on the values of quantum bit error rate and round number. Dynamic linear-feedback shift register circuits have been used to extend the final key. These circuits are dynamically generated by the final key. A unique linear circuit …


Effects Of Polypropylene Fiber Content On Strength And Workability Properties Of Concrete, Yassin A. Ibrahim, Arsalan H. Hasan, Nyazi R. Maroof Apr 2019

Effects Of Polypropylene Fiber Content On Strength And Workability Properties Of Concrete, Yassin A. Ibrahim, Arsalan H. Hasan, Nyazi R. Maroof

Polytechnic Journal

Low tensile strength of plain concrete is due to the inherent presence of microcracks due to drying shrinkage occurrences or other causes of volume changes in concrete. The addition of a proper amount of fibers to concrete would act as crack arrester thus improves its static or dynamic properties. In this paper, the concrete with different amount of polypropylene fiber was investigating to find out the fibers effect on its fresh and mature properties. A plain concrete mix (reference mix) prepared for comparison purposes. Nine concrete mixes were prepared with different fiber volume fraction (FVF) ranging from 0.06% to 2.16%. …


Histological Alterations Induced By Atorvastatin Therapeutic Doses In Some Organs Of Male Albino Rats, Twana Ahmed Mustafa, Hamza Osman Abdulah Apr 2019

Histological Alterations Induced By Atorvastatin Therapeutic Doses In Some Organs Of Male Albino Rats, Twana Ahmed Mustafa, Hamza Osman Abdulah

Polytechnic Journal

Vascular disease and heart attacks are a common phenomenon in the modern world, where lipid accumulates inside blood vessels and causes plug, eventually heart stroke and death. Utilize lipid-lowering drugs are the most effective factors to prevent heart disease. Atorvastatin is the most important drugs that used in this field. The aim of this study was to investigate the adverse effects of atorvastatin (20 mg/kg/b.wt/day) on some organs of albino. 12 adult male albino rats weighing 200 ± 20 g were used and divided into two groups: First group served as control group, was given 0.72 ml distilled water/rat. The …
