Applications of Camera Total Station System (CTSS) in the ConstructionSurveying
...Show More Authors

Engineering structures in general require at implementation conducting
engineering surveys of the implementation stages of work to keep up with identical
implementation of the technical specifications, on the other hand most of the
facilities task (large structures, towers, dams, bridges, etc…) require the
conducting of periodic monitoring to determine any change could happen with time
in the three-dimension( X,Y,Z).
The traditional approach in this proposal for this business is by conducting a field
survey using ground surveying devices in addition to the photogrammetry survey,
regardless of the manner of the work requires the provision of a number of well

Stability and Bifurcation of Epidemic Model
...Show More Authors

In this paper a mathematical model that describes the flow of infectious disease in a population is proposed and studied. It is assumed that the disease divided the population into four classes: susceptible individuals (S), vaccinated individuals (V), infected individuals (I) and recover individuals (R). The impact of immigrants, vaccine and external sources of disease, on the dynamics of SVIRS epidemic model is studied. The existence, uniqueness and boundedness of the solution of the model are discussed. The local and global stability of the model is studied. The occurrence of local bifurcation as well as Hopf bifurcation in the model is investigated. Finally the global dynamics of the proposed model is studied numerically.

DESIGN ASSEMBLER BASED ON LEX AND YACC
...Show More Authors

LEX and YACC are very useful tools for constructing the assemblers; they generate
functions that perform standard operations of a lexical analysis and parsing without
any effecting on the organization processes for semantic analysis, machine code
generation and listing source of compilation. In this work, the cross assembler was
designed using some compiler development tools like LEX and YACC having the
ability to implement the lexical analyzer and parser, for generating the syntax and
parsing modules in a short period of time. These activates are expressed in form of
actions, the bigger number of lexical and grammar rules are used by these actions in

Planetary nebulae (PN) represents the short phase in the life of stars with masses
(0.89-7) M☉. Several physical processes taking place during the red giant phase of
low and intermediates-mass stars. These processes include :1) The regular (early )
wind and the envelope ejection, 2) The thermal pulses during Asymptotic Giant
Branch (AGB ) phase. In this paper it is briefly discussed how such processes affect
the mass range of Planetary Nebulae(PN) nuclei(core) and their evolution, and the
PN life time, and fading time for the masses which adopted. The Synthetic model is

X.K.N: A Proposed Method for Data Encryption Using XOR and NOT Logical Gates with LFSR Generated Keys
...Show More Authors

In this paper, a method for data encryption was proposed using two secret keys, where the first one is a matrix of XOR's and NOT's gates (XN key), whereas the second key is a binary matrix (KEYB) key. XN and KEYB are (m*n) matrices where m is equal to n. Furthermore this paper proposed a strategy to generate secret keys (KEYBs) using the concept of the LFSR method (Linear Feedback Shift Registers) depending on a secret start point (third secret key s-key). The proposed method will be named as X.K.N. (X.K.N) is a type of symmetric encryption and it will deal with the data as a set of blocks in its preprocessing and then encrypt the binary data in a case of stream cipher.

PREDICTION OF RESERVOIR PERMEABILITY FROM WIRE LOGS DATA USING ARTIFICIAL NEURAL NETWORKS

This paper presents a methodology to predict reservoir permeability from well logs data by using an artificial intelligence technique namely artificial neural network. A multilayered perceptron trained by backpropagation algorithm was used to build the predictive model. The performance of the net results was measured by correlation coefficient. The implemented artificial neural network model is demonstrated by applying it to Mishrif limestone reservoir at Nasyria oil field, south of Iraq. The results show that artificial neural network was capable of reproducing permeability (horizontal and vertical) with very high accuracy, so that the calculated correlation coefficients for horizontal and vertical permeability were 0.85 and 0.90, respe

Cryptanalysis is the science and study of methods of breaking cryptographic techniques. Cryptanalytic attack on Merkle-Hellman knapsack using Genetic Algorithm (GA) was done by Spillman. Then Garg et al improved the Spillman GA. The objective of this paper is to harness the power of GA used by Garg et al. to get more reliable results and in less computation time. This paper utilizes a GA, known as diploid GA with exogenous recombination scheme for translating each number in ciphertext into the correct ASCII code for the plaintext characters. Our results are compared with Garg et al. result and they proved that diploid GA with exogenous recombination scheme is more efficient and highly successful in finding the correct bit pattern for the

Leishmania are protozoan parasites belonging to the family Trypanosomatidae that cause high morbidity and mortality levels with a wide spectrum of clinical syndrome. This study aimed to investigate the effect of liposomal amphotericine B (AmBisome) drug on promastigote and axenic amastigote stages of Leishmania donovani isolate (MHOM/IQ/2005/MRU15)in comparison with pentostam SbV drug. Different concentrations of AmBisome and SbV drugs were investigated against Leishmania donovani promastigote and axenic amastigote. The ICR50R values of SbV and AmBisome drugs on promastigote were10.12 mg/ml and 2.21μg/ml, respectively, while they were 0.77μg/ml for axenic amastigote for both drugs.

A batch and flow injection (FI) methods with spectrophotometric detection is proposed for determining of two of phenolic drugs: salbutamol sulphate(SLB)and pyridoxine hydrochloride(PYD) in pure and in pharmaceutical formulations. The methods utilized an oxidative-coupling reaction based upon oxidation of 2,4-dinitrophenylhydrazine (DNPH) with sodium periodate, where an electrophilic intermediate (diazonium salt of the reagent) is produced, which couples with either SLB or PYD in the presence of sodium hydroxide yielding a highly colored condensation product. The absorbance is measured after 15min at 525and515 nm for SLB and PYD respectively. Calibration graphs for both batch and FIA methods were linear over the concentration ranges of 1-
