The six names are names developed by grammarians, so some of them counted them as six, which are (your father, your brother, your father-in-law, Hanuk, Fuk, and Dhu). The Arabs, as explained by Sibawayh and the linguists after him, when this name was contrary to the conditions of grammar, and what we follow in the rules of these words is that they are expressed in letters that linguists call (vowels), while phonologists call them (long vowels), which are (alif, waw, Walia).

Poetry, since its early ages, has expressed the poets’ feelings, thoughts, emotions and feelings, and perhaps fear is one of those feelings that poets experienced, especially since fear is closely related to what affects the human soul so that it makes it feel safe and secure or fear and dread, and this is what prompts poets to express about those positions;

The world has seen and from our Arab significant changes as a result of scientific progress tremendous Born information revolution circulated individuals around the world via the Internet, have left traces extreme depth on their thinking and attitudes in spite of idiosyncrasies that characterize the communities in terms of their cultural, social and nature of education systems where, However, there were some aspects of transformation and change in various areas of life that had a direct impact on the construction of intellectual individuals, and which is no doubt that human beings look alike in respects morphological and biological see them disagree intellectually, everyone has ideas and values​​

Our critical history is marked by the presence of eminent poets who have tried to read, as for their texts, such as Al-Mutanabbi, Ibn Abd Rabu and Ibn Arabi. As for the texts of others, such as Al-Farazdaq, Jarir, and Omar bin Abi Rabi'a, and what is distinctive in their readings was that they were texts corresponding to the reading text, then the reading of Jarir Naqdah and Omar bin Abi Rabi`a was an opposition and Ibn Abd Rabu was scrutinized and Ibn Arabi was an interpretation and al-Mutanabi an explanation, and I found that these in their readings constitute a specificity that must be revealed The way of this research (constructive critical reading by the Arab poet - a critical study -) their poor are critical because criticism is pr

Abstract:

      Talk about bad social life in all aspects and symbols performed poetry, is a modern conductor when the poet Al Basti, the potential depth vision of life, and his psychological balance, especially in the field of relationship, or dealing with others and related relations of manifestations of lattice, which broadcast the poet his emotions direct expression method of formulating a painting and landscape the tale, revealed with its experience in tackling the Al Basti and confront the cons community through display, and here you can glimpse the human journey Life, the discovery of life on a journey replete with events

This paper investigate a sensorless speed control of a separately excited dc motor fed from a buck type dc-dc converter. The control system is designed in digital technique by using a two dimension look-up table. The performance of the drive system was evaluated by digital simulation using Simulink toolbox of Matlab.

This research deals with the design and simulation of a solar power system consisting of a KC200GT solar panel, a closed loop boost converter and a three phase inverter by using Matlab / Simulink. The mathematical equations of the solar panel design are presented. The electrical characteristics of the panel are tested at the values ​​of 1000  for light radiation and 25 °C for temperature environment. The Proportional Integral (PI) controller is connected   as feedback with the Boost converter to obtain a stable output voltage by reducing the oscillations in the voltage to charge a battery connected to the output of the converter. Two methods (Particle Swarm Optimization (PSO) and Zeigler- Nichols) are used for tuning
