Model Dependent Controller for Underwater Vehicle
Get PDFIn this work, a model dependent control design method based feedback scheme was investigated for autonomous underwater vehicle control. The controller was designed with the nonlinear terms - inertia, hydrodynamic damping, and gravitational, and buoyancy - of the vehicle dynamical model consideration. Then, the model independent controller (PD) was also investigated, with no nonlinear terms consideration. The stability analysis of the proposed model dependent feedback controller was obtained based on a Lyapunov function. The simulation results of the proposed controller were compared with that of PD controller. The comparison shows the validation of the proposed controller.

The problem of the distribution of competencies between the federal authorities and the authorities of the Kurdistan Region
No full textتم إقرار النظام الفدرالي في العراق بصورة دستورية في عام 2004 في المادة الرابعة من قانون إدارة الدولة للمرحلة الإنتقالية، كما تم إقراره بعد ذلك في دستور العراق لعام 2005 حيث نصت المادة الأولى منه على أن (العراق دولة اتحادية واحدة مستقلة ذات سيادة كاملة، نظام الحكم فيها جمهوري نيابي (برلماني) ديمقراطي، وهذا الدستور ضامن لوحدة العراق) واعترف في المادة (117) بإقليم كوردستان وسلطاته القائمة، إقليما اتحاديا وحدد الدستوراختصاصات كل من الحكومة الاتحادية واختصاصات الأقاليم في البند الرابع والخامس منه.إن التنظيم الدستوري الوارد في الدستور العراقي قام بتحديد اختصاصات الحكومة الاتحادية حصرا، وأعطى اختصاصات واسعة لحكومات الأقاليم، مع تحديد بعض الاختصاصات المشتركة، ووفقا لهذا تكون حكومة إقليم كوردستان هي صاحبة الاختصاص العام والحكومة الاتحادية صاحبة الاختصاص الإستثنائي، وهذا ما يدعم سلطة إقليم كوردستان دستوريا ويؤكد على استقلالها الذاتي وسيادتها الداخلية، الا أن عملية تطبيق هذه المواد رافقتها إشكاليات مختلفة ولدت مشاكل سياسية واقتصادية متعددة بين الطرفين، وهو ما احدث قصورا في التجربة الديمقراطية الفدرالية في العراق وقد تناول البحث هذه المسألة من خلال مبحثين، الأول يتناول اختصاصات الحكومة الاتحادية وحكومات الأقاليم حسب دستور 2005. والثاني يتناول إشكاليات ممارسة اختصاصات الحكومة الإتحادية وحكومة إقليم كوردستان.
The federal system in Iraq was constitutionally adopted in 2004 in Article 4 of the Transitional Administrative Law of the State. It was subsequently adopted in the 2005 Constitution of Iraq. Article 1 states that "Iraq is a single, sovereign and independent federal state, (Article 117) in the Kurdistan Region and its existing authorities, a federal territory and defined the terms of reference of both the federal government and the terms of reference of the regions in the fourth and fifth of it. The constitutional organization contained in the Iraqi constitution has defined the terms of reference of the federal government exclusively, and gave broad powers to the governments of the regions, with the definition of some common competencies, and accordingly the Kurdistan Regional Government is the general jurisdiction and the federal government with exceptional jurisdiction, which supports the authority of the Kurdistan Region constitutionally Independence and internal sovereignty, But the process of application of these materials accompanied by different problems generated multiple political and economic problems between the parties, which led to shortcomings in the federal democratic experiment in Iraq The study dealt with this issue through two sections, the first deals with the terms of reference of the federal government and regional governments according to the Constitution of 2005. The second addresses Problems of the exercise of the functions of the federal government and the Kurdistan Regional Government

The aim of this research is to find out the availability of requirements and then obstacles in applying the balanced scorecard method in the manufacturing sector because of the importance of this sector in economic development. The importance of choosing the province of Sulaymaneyah as a research population place is due to according to the industrial indicators of the Kurdistan Region Statistics Authority and the Iraq's Central Statistics Organization; the province is considered a more developed model in the industrial sector in Iraq and contains high proportion of small, medium and large, miscellaneous enterprises. The research adopted an analytical descriptive method, where secondary data was collected through a comprehensive survey and access to what was written previously on relevant and then collecting primary data through conducting the questionnaire, in addition to field visits and access to the archive of information on these projects in the relevant directorates. Then the descriptive and inferential statistics were used to organize, display and analyze the data and to arrive at accurate results and realistic conclusions and so that the researcher formulated a set of recommendations according to the conclusions. The results showed that the financial perspective remains the highest priority among all other perspectives (Customers, Internal processes, learning and growth) perspective. And most of the firms lack strategic management and they do not have the basic requirements and there are actually a number of obstacles to the application of this tool. It is expected that the results and recommendations help the decision makers of industrial enterprises to adopt and move towards the implementation of the Balanced Scorecard more broadly. The results of the research confirm some of the prevailing theoretical concepts and recommendations provide possible solutions or help for institutional changes to enhance performance management generally. Finally, the numbers of the future research were proposed

Support Vector Machine and Back Propagation Neural Network Approach for Text Classification
Get PDFText classification is the process of inserting text into one or additional categories. Text categorization has many of significant application, Mostly in the field of organization, and for browsing within great groups of document. It is sometimes completed by means of "machine learning.". Since the system is built based on a wide range of document features."Feature selection." is an important approach within this process, since there are typically several thousand possible features terms. Within text categorization, The target goal of features selection is to improve the efficiency of procedures and reliability of classification by deleting features that have no relevance and non-essential terms. While keeping terms which hold enough data that facilitate with the classification task. The target goal of this work is to increase the efficient text categorization models. Within the "text mining" algorithms, a document is appearing as "vector" whose dimension is that the range of special keywords in it, which can be very large. Classic document categorization may be computationally costly. Therefore, feature extraction through the singular valued decomposition is employed for decrease the dimensionality of the documents, we are applying classification algorithms based on "Back propagation" and "Support Vector Machine." methodology. before the classification we applied "Principle Component Analysis." technique in order to improve the result accuracy . We then compared the performance of these two algorithms via computing standard precision and recall for the documentscollection.

The Future of Technology-based Classroom
Get PDFIn recent years, Information Technology (IT) has turned out to be a standout amongst the most essential social practices of the Iraqi society. Technology has developed in many areas in Iraq, yet internet and computer technology is not implemented in every classroom in most of Iraqi universities. The aim of this paper is to question: why technology is not executed in the classroom of the universities? The point of this contextual analysis is to recognize the difficulties that face university organizations from executing computer technology in every classroom with support of ministry of higher education. Another question is: how popular or effective could the application of computer communication or computer application in the classrooms of our graduate students be when it comes to education? This study wants to uncover the underlying issues and reasons for the in capabilities in using technology. To examine this, the researchers inspected cases of teaching where technologies used in the classrooms as a lived experience and as an apparatus for encouraging direction while instructing in the universities. The outcomes show that the country's current educational and telecommunications infrastructure is weak and the ministry of higher education and universities need to manufacture the framework limit of schools, and furthermore to enhance educator preparing programs at all levels.

Transmission Control Protocol Global Synchronization Problem in Wide Area Monitoring and Control Systems
Get PDFThe electrical power network is a significant element of the critical infrastructure in modern society. Nowadays, wide area monitoring and control systems (WAMC) are becoming increasingly an important topic that motivates several researchers to improve, develop, and find the problems that hinder progress toward WAMC systems. WAMC is used to monitor and control the power network so the power network can be adapt to failures in automatic way. In this work, verification of the extent found a problem in transmission control protocol (TCP) which is called global synchronization and its impact on utilizing the buffer of the routers. A simulation models had been belt of WAMC system using OMNeT++ to study the performance of TCP in two queuing algorithms for measuring transmission of phasor measurement units and to test if global synchronization problem occurs. Three scenarios were used to test the survival of this problem on the system. It is found that the problem of global synchronization occurred in two scenarios which in turn causes low utilization for a buffer of routers.
