Abstract

In this paper we introduced and study two concepts one of is a subclass of a class of weakly primary submodules called WE-primary submodules and the other of a subclass of weakly quasi-prime submodules called WE-quasi-prime submodules. Several properties of WE-primary and WE- quasi - prime submodules have been given, and some characterizations of each type of submodules are introduced moreover behavior of these submodules in some classes of modules are investigated. On the otherhand, the homeorphic and inverse image of these concept under certain conditions are proved

Abstract

Wind energy became one of the techniques that attracted much attention worldwide. The induction generator is used in the exploitation of this energy and converts it into electrical energy because of the advantages that distinguish it from other types of generators. In this paper, an optimal identification of induction generator parameters is proposed. Particle Swarm Optimization technique (PSO) trained using Artificial Neural Network (ANN) is used to identify the main parameters of the induction generator in cases of wind speed change, load change and fault cases.The simulation results obtained indicate that the particle swarm optimization is suitable for neural networks training for controlling of the voltage, frequency and generated power. The simulation programming is implemented using MATLAB.

Abstract

" In the Name of God , the Merciful , the compassionate Our Lord , make not our hearts to swerve after that thou hast guided ; and give us mercy from thee ; Thou art the Giver . "( the Glorious Qur'an , 3: 8 )Thanks for our God , we thanks him , forgive him , peace be upon mohammad Ibn Abdullah ( PBUH ) because the God choice him for his book , Al-Qur'an,and peace upon his folks and his loyalists who believed and support him .It is very important to studying the holly Qur'an by any Muslim in order to know the security of it , then believing of God may be become greater than before . When we are studying The Holly Qur'an or by any Muslim make us believe for the prohet and knowing how the holly Qur'an explained all the problems in the world ( life and after death ) and how we know the simple solutions for them , on the other hand we know from studying it the causes of the strength besides the causes of weakness for the Islamic nation .When the students studying the holly Qur'an they will know it breeding prophet's followers and how it learning them the manner of calling as well as how they are behaving against the difficulties . Also from the Holly Qur'an we know the right position in the society in order to stand against the difficulties .As a result , we must work hard to weak up our Islamic nation from its weakness because we knew the reasons of it from the references in ( AL-AMRAN ) in the Holly Qur'an so we must return to it , if we would want to working out the treasures ( means sciences , wisdom , believe , rights , wrong , and so on ) from it .My God helps me to join to Islamic Studying so I wrote this study when I am living and I saw what had happened to our great Islamic Nation . then I decided to began this study in order to find answers to some questions , one from them , why did our nation life in a weakness on different field , thinking , social and political , those makes me choice this subject because I hope to explanation what our nation suffers from .The important things of this subject :Nowadays , the people in the word , especially Iraqi people suffering from big difficulties in different sides. Society's problems are quarrelling, revolt , and tearing the relationship between the native people , which took place because the politician's conflict . How did it that happened ? When we try to analysis the cause's conflicts , we can find answer to this question , so I suppose there are some reasons leading us to the solution , one of them to change the way of thinking about our people in the society .Another reason to the difficulties, that weakness took place in our nation because we held the similarities of things and leaves good things

Abstract

In this paper we report the result of investigation of the variation of discharge current in rectangular tube with discharge voltage for N2 and CO2 gases, these experiments are conducted for gas pressure from (0.75 Torr) to (7.5 Torr). Sparking voltages are measured for these gases over this range of pressure as well as the relations between electric field (E/P) with (P), variation of discharge resistance (R) with (P) and conductivity ()as a function of (P). These results show that the sparking potential vary with the product (pd) in accordance with paschen curve. The discharge characteristic is similar to the conventional discharge tube except the relation of (E/P) as a function of (P) .

Abstract

The main aim of this work is to introduce the acceleration methods which are called the inverse triangular acceleration methods and inverse hyperbolic acceleration methods, which are considered a series of numerated methods. In general, these methods are named as AL-Tememe’s acceleration methods of first kind discovered by (Ali Hassan Mohammed). They are very beneficial to acceleration the numerical results for definite integrations with continuous integrands which are of 2nd order main error, with respect to the accuracy and the number of the used subintervals and the speed of obtaining results. Especially, for accelerating the results which are obviously obtained by trapezoidal and midpoint methods. Moreover, these methods could be enhancing the results of numerical of the ordinary differential equations, where the main errors are of 2nd order.

Abstract

In this paper we have made different regular graphs by using block designs. In one of our applicable methods, first we have changed symmetric block designs into new block designs by using a method called a union method. Then we have made various regular graphs from each of them. For symmetric block designs with λ=1 (which is named finite projective geometry), this method leads to infinite class of regular graphs. With some examples we will show that these graphs can be strongly regular or semi-strongly regular. We have also propounded this conjecture that if two semi-symmetric block designs are non-isomorphic, then the resultant block graphs of them are non-isomorphic, too.

Abstract

The Babylonians introduced the greatest of civilizational achievements in the history of mankind in different branches of knowledge, especially mathematics, because it is the language of sciences and the basis upon which the other sciences are built, such as astronomy, physics, chemistry, geometry and etc….Actually, the achievement, that took place in Mesopotamia are regarded as the cornerstone of all inventions that appeared in different adjacent countries and in later different periods. Also, the remains and the information that came down to us underline the greatness of this people and the originality of this civilization(1). Because of this development, we preferred to focus on a type of mathematics which is seen as one of the natural consequences of the economic and intellectual development in Mesopotamia. Despite its initial steps which are considered experimental knowledge, it Later took important steps towards discovering a number of scientific facts that resulted from the abstract theoretical meditations

Abstract

The objective of this paper is, first, study a new collection of sets such as –field and we discuss the properties of this collection. Second, introduce a new concepts related to the –field such as measure on –field, outer measure on –field and we obtain some important results deals with these concepts. Third, introduce the concept of null-additive on –field as a generalization of the concept of measure on –field. Furthermore, we establish new concept related to - field noted by weakly null-additive on –field as a generalizations of the concepts of measure on and null-additive. Finally, we introduce the restriction of a set function on –field and many of its properties and characterizations are given.Keywords: –field, measure on –field, monotone measure, null-additive.
