Optical Design of Laser Zoom Beam Expander at near & far Ranges for Tracked Atmospheric Target
...Show More Authors

In this research, beam expander, BEX, is explained and designed for illuminating the
remote flying target. The BEX is optically designed to be suited for Nd:YAG laser of given
specifications. The BEX is modified to be zoom one to meet the conditions of preventing the
receiving unit; i.e the photodetector, from getting saturated at near and far laser tracking.
Decollimation could be achieved by automatic motor, which controls zoom lens of the BEX
according to the required expansion ratio of beam expander

The of Effect Instructional Design based on Kagan Structure In Generating Information Skills for First Intermediate Student’s In Mathematics
...Show More Authors

 

The aim of the research is to identify the effect of instructional design according to Kagan structure among the first intermediate school student’s, and how skills could help in generating information in mathematics. In accordance with the research objectives, the researcher has followed the experimental research method by adopting an experimental design with two equivalent groups of post-test to measure skills in generating information. Accordingly, the researcher raised two main null hypotheses: there were no statistically significant differences at the level of significance (0.05) between the average scores of the experimental group who studied the material according to Kagan structure and th

Formal Data of Bauhaus School and their Implications for Fabrics and Costumes Design: نور منصور خميس-وسن خليل ابراهيم
...Show More Authors

The current research discusses the topic of the formal data within the methodological framework through defining the research problem, limits and objectives and defining the most important terms mentioned in this research. The theoretical framework in the first section addressed (the concept of the Bauhaus school, the philosophy of the Bauhaus school and the logical bases of this school). The second section dealt with (the most important elements and structural bases of the Bauhaus school) which are considered the most important formal data of this school and their implications on the fabrics and costumes design. The research came up with the most important indicators resulting from the theoretical framework.
Chapter three defined the

Praise be to God, Lord of the worlds, and prayers and peace be upon the master of the messengers, his family and all his companions. And after:
      This research talks about a topic that has taken a great deal of attention and controversy among many Arabic language scholars, which is the subject of poetic necessity, but it does not talk about the necessity in general, but one of the scholars and writers who had stances and references to this issue was chosen in many places from their books. Abu Al-Ala 'Al-Maari was among the scholars who dealt with this issue on numerous occasions and occasions, and this was evident in his books.

The Islamic thought still suffers from the problems posed by Western thought in the modern era, especially after the establishment of the modern Arab state, and replacing the intellectual reference that prevailed at that time, which is represented by Islamic thought with another intellectual reference represented by Western thought. Since then, thinkers and innovators and reformers and intellectuals of the Islamists, Are trying to get out of these many problems and multiple, after imposing the nature of that thought and those references with all their consequences, and one of these problems that is still Islamic thought suffers, the bilateral problem that some academics have raisedThe title of the symposium failed The Islamic thought and

Through the title of the research, it is clear that beliefs in different religions are considered the important principles that distinguish religions, sects, and sects from each other, and belief is the important foundation and pillar on which the individual and society is based, because God Almighty called for reflection and reflection to choose his peaceful belief away from blind imitation. It is (belief in the existence of God, and His unification - and glorifying His attributes - and belief in the prophets in general, and belief in the angels in general, and in the revealed books in general).

DESIGN AND VALIDATION OF A LOW−COST WIRELESS ELECTROMYOGRAPHY SYSTEM : DESIGN AND VALIDATION OF A LOW−COST WIRELESS ELECTROMYOGRAPHY SYSTEM
...Show More Authors

Electromyography (EMG) is being explored for evaluating muscle activity. For gait analysis, EMG needs to be small, lightweight, portable device, and with low power consumption. The proposed superficial EMG (sEMG) system is aimed to be used in rehabilitation centers and biomechanics laboratories for gait analysis in Iraq.

The system is built using MyoWare, which is controlled by using STM32F100 microcontroller. The sEMG signal is transferred via Bluetooth to the computer (about 30m range) for further processing. MATLAB is used for sEMG signal conditioning. The overall system cost (without computer) is about $80. The proposed system is validated using wired NORAXON EMG using the mean root mean squared metho
