Due to the increasing development in using modern technology for different
purposes, recommendation systems have become essential in providing solutions
to all users. Recommendation systems can be used for various applications or on
the internet to purchase products or to surf the web for scholarly articles, to watch
videos and other activities. Many statistical and mathematical suggestions have
been made to make different systems capable of giving accurate recommendations
that can be of benefit to users in various fields. One of these suggestions is Singular
Value Decomposition (SVD) which is the most popular method in previous
research. In addition to that, (SVD) has two important factors in its performance,
which are, (???? , ????) and choosing these two factors plays an important role in the
accuracy of recommendation systems. Choosing these two factors was a heavily
discussed topic in previous academic research. In this paper, the use of artificial
intelligence method Genetic Algorithm (GA) to design a hybrid system with the
Singular Value Decomposition (SVD) to specify the best values of (???? , ????), and
hence acquiring an accurate recommendation system with better speed. After
several experiments, the results indicated that the hybrid system better system
according to time. The hybrid system (GA) is also better than the system uses
(SVD) in accuracy and time

Dust storms are the most significant weather phenomena affecting Iraq and greatly degrading ecosystem and human health. There has been an increase in the frequency of dust storms occurrence in Iraq and bordering countries of Iran, Kuwait, and Saudi Arabia. The aim of this research was to assist the variability of dust storms over Iraq using remotely sensed data. Monthly means of Absorbing Aerosols Index (AI), satellite images, rain and wind were respectively acquired from TEMIS, MODIS, and MERRA-2 websites for a period of 10 years (2003-2012). Results of comparisons between MODIS images and AI maps for a dust event showed that AI provides a good indication of the initiation, development and transportation of dust particles. Analysis of 10 years data indicated that the majority of dust events over Iraq are caused by the northwesterly wind (shamal wind) and the highest values of AI occur during the summer months. Southern cities of Basra and Nasiriyah are the most affected cities by dust storms while the central cities of Baghdad and Anah are less affected. Dust activities over Mosul and Rutba are relatively lower than those in the other four cities. This may be attributed to relatively slower winds and much less sources of dust particles around the two cities. Results also showed that rainfall plays an affecting rule in the occurrence of dust storms. It was found that when rain increases in certain year AI tend to decrease in the flowing year.

In this paper, synchronization is theoretically investigated in two quantum cascade semiconductor lasers coupled with delayed negative optoelectronic feedback under effect of time delay. Synchronization quality and the influence of times delay mismatches on synchronization performances are investigated. The results indicate that the complete synchronization can be realized under suitable system parameters. Such as, the delay time of the transmitter, the delay time of the receiver, and transmission time have a significant impact on the synchronization quality. Calculations indicate that the correlation coefficient can be enhanced by similar delay times.

Military units are suffering, especially during the winter from lack of proper positioning and camping areas in the hills and valleys due to road outages and communication among the components of the pieces and military units due to the floods and monsoon rains. For this reason it can be used satellite images and for digital elevation model (DEM, Digital Elevation Models) with some chock programs and specialized in remote sensing, such as programs (ArcGis), to obtain positive results in determining the logic that is likely to flood the water and find the best camping areas which are close to the movement areas and Supply and paved roads and unpaved, and all presence areas such as fixed units, such as medical care and supply centers and certain fixed pieces of heavy artillery.In this paper we use the satellite images (ASTER), which is characterized by precision (30 M). And use of a mathematical model to find flooded areas originally and potential low-lying areas inundated with floodwaters that as we can in this mathematical model to identify river basins permanent or seasonal zones consisting of rain. The river basins and low-lying areas could be excluded from the camping areas for military cuts. As we can see through the river basins of finding the edges of the docks and areas that are an impediment to the movement of vehicles and military vehicles.

The species of the genus Aspergillus have an ability to produce secondary metabolites, however, not all filamentous fungi can form the metabolites. The current study showed that two species of the genus grew at 27 °C on potato dextrose agar (PDA). Aspergillus terreus appeared brown colonies on the PDA but A. niger grew as black colonies. Potato dextrose broth (PDB) used to be a fermenting medium by which the fungal filtrate of both fungi separated from the mycelia. Residues of the extracted filtrates gave the blackish brown crude extracts. The extract weights recorded 300 mg/L obtained from A. niger, and 200 mg/L of A. terreus. GC-MS analysis revealed the extract of A. niger consists of three compounds are {[5-methyl-2-phenylindolizine],[thiocarbamicacid,N,N-dimethyl,S-1,3-diphenyl-2-butenylester], and [22-beta.-acetoxy-3.beta.,16.alpha.-dihydroxy13,28 epoxyolean-2]}. A. terreus extract possesses four compounds are {[2.2] paracyclophane, [5-methyl-2-phenylindolizine],[2H-1-benzopyran-6-ol,3,4-dihydro-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltride)], and [dI-.alpha.-tocopherol]}. 300 µL taken from 10 mg/ml of A. niger crude extract led to hemolysis of red blood cells while 800 µL of the same concentration from A. terreus extract gave the hemolysis. The present study concluded that 5-methyl-2-phenylindolizine was detected a similar compound in crude extracts of both A.niger and A.terreus with the same retention time. It may be attributed to the presenting same gene within the genome of both fungi led to producing 5-methyl-2-phenylindolizine.
