المستخلص: Cloud computing considers an important paradigm that provides services and dynamic virtual resources to the consumers over the internet.One of the main challenges and important fields for research in the cloud computing environment is load balancing. So the main goal of this thesis is to establish an effective load balancing algorithm for task scheduling. In cloud computing environment, the demands are executed into the virtual machines (VMs) and in the execution, it must be avoided a situation some of the resources are under loaded states while there are resources overloaded or heavy while achieving less the execution time of the tasks andresponse time. In this thesis, we present the Load Balancing Decision Algorithm (LBDA) which aims to achieve load balancing for reducing the : Total completion time (Makespan), Response time and Total execution time of tasks in cloud computing environment.The mechanism of LBDA is based on three functions, first : calculating the virtual machine capacity, virtual machine load then determining VM states (Under loaded, Balance, High balance, Overloaded) based on comparing VM capacity, VM load and using three thresholds : threshold upper; threshold fair; and threshold lower. Second : estimating the time required to complete executing the task in each VM. Finally, making a decision to distribute the tasks among the VMs based on VM state and task time required. Where checked task time required into VMs under states and selecting the fastest VM, when there are more than one VMs have the same time to complete a task, LBDA assigns a task to VMs which has the largest capacity. When all VMs become (Balance or High balance) states, the tasks are distributed between VMs depending on the fastest execution. The proposed LBDA was compared with Max - Min, Shortest Job First and Round Robin algorithms. We applied many experiments with various VMs’ capacity and : A different number of tasks on a different number of VMs, The same number of tasks on a different number of VMs, and A different number of tasks on a different number of VMs.The performance evaluation results implemented in cloudsim toolkit 3.0.3 and the experiments demonstrate that our proposed LBDA outperformed to other algorithms by reducing the completion time of tasks, response time, andtotal execution time of tasks.

المستخلص: In recent years, the statistics presented high incidence rates of breast cancer.So, early detection of breast cancer considered one of the highest healing rates for most cases, where the treatment at early stage is very easy and involves removal to malignant tumor from breast without needed to remove all breast. As well the cost of treatment is very economical with early diagnosis, while at a late stage, the cost associated with treatment is higher. In addition, the prevention have role to reduce risk by avoid catalysts that cause Incidence and associated with risk factors. For these reasons and others, we present the proposed method for designing a risk assessment tool for breast cancer prevention and early detection based on demographic risk factors (DRF) and using Neuro - Fuzzy System (NFS) in designs risk assessment model that help doctors and patients in assess risk of Incidence through providing better and more reliability results.In this thesis, the proposed method is a process of several stages. The first phase included statistical study to identify problem of research based on statistics in Basra, through apply the study on patients community at Al - Sadir Teaching Hospital in Basra (Oncology Center), that represent main center in Basra for the treatment of cancer. Three and most important phase includes the proposed approach for design assessment model using Neuro - Fuzzy system (NFS) in two approaches. the second approach suggested using Fuzzy c - means (FCM) algorithm with Neuro - Fuzzy system to improve the first approach that just use Neuro - Fuzzy system (NF). The proposed method is focused to solving basic research problem to prevention and early detection of breast cancer.The proposed method achieved high results when compared to other methods and tools. The success rate of proposed assessment tool is 94%, and it is higher rate among other assessment tools (Gail, IBIS) that obtained by match the result for assessment of test data (50) with the expert opinion (the real result). Programming and testing of proposed method by used Matlab 2013

المستخلص: The rapid development and tremendous computer and communication technologies and the proliferation of global networks, has led to the emergence of many techniques to transfer confidential information including encryption (Cryptography), and as a result of piracy And penetrating these techniques need arose for techniques and methods more sophisticated and difficult to transfer confidential information securely. Because of the increase in the number of attacks recorded during the exchange of electronic information between the source and the recipient may need to use a more powerful way to secure data transfer, encryption methods are combined And hide the information together for the purpose of setting up a mechanism to improve confidentiality and because these methods shared goals and common services in protecting the confidentiality, integrity and availability of information from unauthorized access and thus check mechanism High security integration to preserve data confidentiality.The research aims to use the method to hide secret information (picture or sound) into audio files (audio file) (wav) as cover in such a way as to ensure that information is not piracy, secret message encryption Sleek encryption before concealment by making the size of the stego - audio is equal to the size of the original file.As the audio file is the output of a process of hiddin similar to the original file and for the human ear to feel the change. By segmenting the original soundtrack cover frames (frames) and apply the random function to locate hidden after the colored image layers in case confidential information picture or sound to hide the hash to Frameworks and then applying the function for selecting locations for concealment and then apply the least significant bit technology (Siginfcant Least Bit) for concealment.In the case of the recovery process is contrary, embedded audio file fragmentation occurs (stego - audio) and apply the random function for selecting locations for concealment and decrypt the message.Use a key in a hash process sound represents the size of the picture you want to hide, and it represents the number of frames (frames) and serve as a key to encrypt the original audio as we use an algorithm to generate a sequence of key Homologous between the sender and recipient to Sleek encryption to increase security. The recovery process success ratio for the image dB 99.0, audio retrieval process was well proportioned. , We used Image metrics (PSNR), (SNR) and the inclusion ratio between the confidential letter and sound and cover (RMSE) between audio - stego and original sound. And high results were obtained about (85 - 95 )when recovery without any mention on the file (Stego_audio).

المستخلص: Turkey can't be described geographically by it's subordination to one territory only, Its regional structure makes it capable of maneuvering in more than one area at a time to appear to control a very wide area of influence. Its area is composed of the confluence of two continents : Asia, Europe and only the Mediterranean from the northern shores of Africa .This unique geographical location is of great importance and its regional and international status. The study is problematic because of the nature of Turkey's regional role towards the Gulf states, the reasons for this trend and the impact of the natural and human characteristics of Turkey and the Gulf countries on Turkey's direction .The Justice and Development Party (AKP) recognizes the government and its role in the events of the change in Turkey's policy from 2002 to 2017 (present time), the impact of the regional changes that occurred in the Arab region due to the occupation of Iraq in 2003 and the repercussions of the so - called Arab Spring in 2010, Syria and Libya, and this vacuum produced an Iranian expansion is not welcomed by the Gulf States and the United States and the West, so emerged the need for Turkey, which has the characteristics of natural and influential human characteristics combined with the Gulf countries and the most important Islamic religion to try to work to balance the expansion of Iran in the region, energy resources Especially the oil and gas, which lacks Turkey from the Gulf countries of strategic and geo - economic importance regionally and globally towards the consumer markets, as well as highlighting the failure of Turkey to join the European Union, which motivated the direction of the Arab Gulf States (the Arab Cooperation Council), which was focused on the exception of Iraq, The researcher used a number of analytical, regional and functional approaches, in order to demonstrate the importance and nature of the role that Turkey wants to play through its orientation to the region. The research was divided into five chapters, The first chapter dealt with the natural characteristics of Turkey, while the second chapter focused on human characteristics. The third chapter dealt with the most important characteristics attractive to Turkey in the Arabian Gulf region .The fourth chapter dealt with the variables that affect Turkey's orientation, namely internal variables in Turkey, Iran, and international variables touched on the United States, the Russian Federation and the European Union, and through the introduction of three future scenes of the nature of the relationship between Turkey and the countries of the region between the scene of a strategic alliance, or the scene of a transitional tactical alliance or the scene of decline of relations , A researcher with the tactical alliance , and the study ended with the most important conclusions and proposals
