المستخلص: This is a study of ( the regional status of Israel and the events of 11/septemper/2001 - a study of potentials and opportunities) by analyzing the variables which helped in the maintenance of Israel existence within a strange environment, and its relentless and continuance attempts to reach the regional domination statues in a region considered one of the most vital regions of the world; extending from Iran in the east to Sudan and Egypt in the west and from Turkey in the north to the Arab gulf in the south . This very region has constituted the middle east according to the British vision in the near past ,and today it is the beating heart of the great middle east project the united states is planning for. The Israeli search for a significant regional statues in this region has been quite unique due to its up normal establishment and its social, historical and cultural radical difference from other countries of this region. Thereby, Zionism realized the danger threatening this new born state among a hostile environment, that is why its purposes and aims have been arranged according to the priorities of planning for state establishment , in cooperation and coordination with the international powers which has an influential impact on the political system : earning the international and legal legitimacy required for the establishment of the state of Israel, fulfilling the Jewish destination, start up the Jewish immigration , preserving the state entity by building a powerful army relying on a huge reserve power capable of defending the state. In order to achieve these goals it has to own the power in every aspects and domain which creates superiority in quality over the hostile Arabic mass. This inspired the idea that the relationship of powers indicates obvious Israeli superiority since the establishment of Israel to the present day, enhanced by the Israeli cultural devotion for the superior west and the Zionist ideological power. Despite Israel capability of achieving the international legitimacy in existing , it did not cancel its great interest of having this regional role and an Arabic acceptance allowing for interacting and influential role in the region. Thereby, there are some of the priorities that constituted the frame of the Israeli political and intellectual perception of its geographical region : 1 - relying on a great power, first obtaining its protection ,and its constant support which qualifies it for a regional role secondly . 2 - embrace the absolute security conception based on geographical extension in order to ensure the strategical depth and secure military superiority maintenance supported by deterrent nuclear arm.3 - The assertion on the elimination of Arabic nation as a cultural and historical fact and finding some sort of religious and national conflict in the sense that it uses religion as a mean of wreaking the Arabic nationality as well as exploiting the sectarian and religious tensions for breaking down the region which fulfills the admission and acceptance of others ; and obtain the regional legitimacy by establishing an Arabic climate accepts the Israeli existence and cope with it to reach for the regional dominance in further level and play the role of regional leader. What helped Israel to accomplish so much of these goals and visions sum of the international variables that stormed the international political system found their echoes in the region which Israel took it for its advantage and used it brilliantly : by the end of cold war Arabs lost their stragical ally (the soviet union) which created the opportunity for Israel and united states to enforce the settlement on Arab. Followed by this golden opportunity, the attacks of 11/septempper /2001 which reached American depth, Israel seized to finish on the Arabic regime, since the prepecations of these attacks concentrated on the middle east core which Arabs and Muslims represent the majority . here, the study proves its hypothesis that accusing Arabs and Muslims of terrorism , distorting the image of Arabs and Muslims making them the target for the American war against terrorism , occupying Iraq , intensifying the American military presence and making the region go through turmoil to distort the region image ; all these are positive outcomes in the advantage of Israel to back up its policies and practices in the region in order to promote its regional statues supported by an American devotion during the region of the current American administration of George Bush junior never reached before. Consequently the study attempted to draw future portraits of the Israeli regional statues promoting two of them which are the most convenient for the Israeli interest : the portrait of continuity , and the portrait of continuity and change for the long and short range. The study has concluded into sum of the deductions confirming the reality that Israel being an important regional state for the time being , it is more than enough to say that it’s the most developed and advanced state and the only nuclear power in the region.

المستخلص: The region of West Africa has occupied a great strategic importance in America's foreign policy, especially after the cold war, as this policy witnessed an observed American movement towards this region with the beginning of the 1990s of the last century under the changes that the world had witnessed through that period which represented in the disassembly of the Eastern system (Soviet Union) and the uniqueness of The United States of America in the world which is regarded as the only prevailing pole in the international domain. Therefore it followed a foreign policy which is built on that grounds, and fits the nature of the new phase. So, the world has become in front of a unique situation that embodied in the domination of one pole and its attempt to oppose its politics and will on others. Thus, its policy is considered universal and global that comes from the truth that its interests are distributed all over the world. As a result, it is necessary to subject the world to that policy and especially those regions that have a great strategic importance for The United States of America. Among these important regions West Africa's region that is considered one of the most remarkable region in the African Continent which takes a notable place in America's foreign policy according to its great significance on different levels whether political, economic, strategic, or security level. On the economic level, West Africa's region is considered a huge store for raw and unprocessed materials, as well as for sources of necessary energy like oil and gas, which American industry needs greatly. As to the security level, this region becomes very important in America's foreign policy according to its economic importance from one side, and its position among other regions that are included in the American war on terrorism from the other side, a matter that makes this region has a direct relation with American national security. Politically, The United States of America sought to win the attitude and approval of other countries of the region especially in the issues that have a relation with America's goals and interests. However, West Africa's region strategic importance comes from its strategic position which lies near the eastern coasts of The United States of America. So, as a result this makes America's reach to it is easy and getting all what it needs securely and easily. On the basis of all these facts, The United States of America has realized that this region becomes associated with its national security because a great part of its interests is associated with this region. Yet, this leads The United States of America to use variable means and ways that allow it to control the resources and treasures of the countries of the region. Hence, we notice that The United States of America has employed all the means of a foreign political action toward achieving its goals. Therefore, it moved politically through its managers and bosses, as well as holding sessions and conferences that gather both sides, in addition to reinforce the American diplomatic presence through opening new embassies and consulates in most countries of the Continent. As for the economic side, the American policy towards West Africa takes various shapes and directions. Sometimes it uses economic assistance and support as a means of perfusion to that region. Most of America's assistance and support are accompanied with economic and political conditions that touch the sovereignty and independency of the country that receives the assistance. Other times it uses investments and the spread of the gigantic American companies in West Africa as a means of economic domination on the countries of the region, especially after the increase of American dependence on the African oil greatly, in addition to all that, its dependence on the raw materials that are found in large amounts there and used in American industry. On the military level, West Africa witnessed an observed American activity which took different shapes. Sometimes it takes the form of a direct military intervention in the affairs of these countries, as what happened in Liberia in 2003. Other times it takes the form of military support through supplying the institutions of these countries with all what they need from military experiences and consultations, as well as opening sessions for African soldiers in The United States of America from one side, and from the other side, they send American experts to West Africa to supply them with what they need from military experience and consultation. By this action, The United States of America was able to turn the region into what is look like a military base for it to launch anywhere that may threaten its security and interests all over the world. This is revealed by its announcement of formation American military leadership (AFRICOM), since this action shapes one of American political dimensions to achieve its security goal. Nevertheless, this policy was not far from the international competition which glows between the international rising countries that attempt to control and dominate the treasures and sources of this region, and one of these forces is France and China which activate greatly in West Africa. As for France, it was a previous colonizer of the west of the Continent, while China is considered the dragon that searches for energy sources and necessary raw material for its rising and improving industry. These actions raise Washington's fears from losing its control on the region. Therefore, The United States of America moves towards all levels, whether politically, military, or economically in order to prevent the rise of any international competitive forces to it in the region.Consequently, The United States of America moves towards reinforcing its relations with all countries of the West African region especially those countries that have a political, economic, and military importance, whether on Continental level, or on international level. Perhaps one of these countries is Nigeria which becomes the most powerful strategic alliance to The United States of America in the African Continent. Hence all America's foreign policy and movements aim to control and dominate this strategic region and to protect its goals and interests there, in addition to its attempt to oppose its western liberal pattern on the countries of the region. From all above, we can conclude that : 1. West Africa's region is considered one of the most important strategic regions for The United States of America, and its importance is increasing according to its political, economic, and security importance. 2. The variation and multiplicity of the means and mechanisms of the American action towards West Africa in a way that allows and justifies America's free action there, and be insure of opposing its domination on the sources and fortunes of the region. 3. Due to its richness with sources of energy and raw materials, The United States of America sought to put a hand on these sources and raw materials that are found in this region, in addition to protect the American companies' interests there.4. Taking advantage from African market in general, and from the market of the west in particular, because from one side it will be a promising consumptive market for American goods and merchandise for more than 300 million human beings. From the other side, The United States of America will create work chances for America's new generations in the future.5. The increase of American dependence on importing oil abroad especially from African Continent which probably will reach to 25% in 2020 which leads America to consider West Africa one of the most important regions that it will depend on in the future, especially Guinea gulf which is rich with petroleum, a matter that leads many to say that Guinea gulf will be the substitute for the Arab gulf, for The United States of America, according to its huge petrol supply and the increase of the discovered quantities in it from one side, and because of the decrease of the Middle East oil (Arab gulf), as some records indicate, through the coming years, from the other side, in addition to the state of instability that the region witnessed which threaten the access of petroleum supplies to The United States of America.6. Facing the domination of the rising international forces in West Africa especially the French and Chinese dominations, and the attempt to weakening their role, in addition to depriving them of getting any privileges that they may have to get resources and treasures of this region and investing them, as well as depriving them from dominating on its huge markets in order not to be at the expense of America's goals and interests.7. The seeking of The United States of America to create strategic alliances in the region which have a military, economic, political, regional, and international importance, which can depend on in carrying out its foreign policy. Therefore America finds Nigeria (the African giant) the most important and active country in the west of the African Continent

المستخلص: This dissertation is concerned with studying the foreign policy of the United States towards the Eastern Arab countries after the cold war. It consists five chapters with an introduction and a conclusion.The first chapter tackles the development of the American policy towards the Eastern Arab countries and its aims. It is obvious that it did not take a special feature only at the end of the second world war. From the end of 18th.century on , the American policy was concerned with some economic interests especially with oil and some other cultural and religious concerns like those made by some protestant missionaries in different Eastern Arab countries. After the second world war when there was a great need for oil, the region has captured the interest of the American decision maker gradually. In addition, the increasing of tension caused by the cold war was another reason that the region becomes of increasing value for the Americans. It is possible to say that the most important American aims in the region are economic and cultural in order to generalize the American type besides other strategic and security aims.The second chapter studies the important features effective in the American foreign policy towards the Eastern Arab countries. The deconstruction of the Soviet union appears to be the most distinguishable international feature that enables the United States to impose its policies on the region. With out having an opponent , the region suffers some kind of political submission in order to be re - formed. The Iraqi occupation of Kuwait in 2nd of August 1990 was among the most important regional features that helped in prevailing the American policy in the region more than ever. More over, this chapter concentrates on studying other regional factors " variables" that work to suppress the American policy in the region, like the Islamic extremism and spreading of the weapons of mass destruction and terrorism. It also studies the features that helped in the success of the American policy in the region like the strategic role played by Israel and the existing of non - democratic regimesThe third chapter discusses the units and the institutions responsible for the foreign political decision - making. It is divided into two sections. The first section studies the formal units represented by the president, the role played by both the ministry of defense and the state secretary, in addition to the CIA and the national security council and the congress in determining the American foreign policy. The second section is concerned with the non - formal institutions effective in foreign policy decision - making, like the political parties, the Zionist lobby, the economic - military factor, besides the important role played by the institutions of research and thought development" Think - Tanks".The fourth chapter tackles the American foreign political behavior towards the region. It is divided into five sections. The first studies the American foreign political behaviour towards Iraq. The second one specializes with studying the Arab - Israel conflict and the attitude of the United States towards the Palestinian Issue. The third section focuses on the American attitude towards Syria. The fourth one deals with the American behaviour towards the security of the Arab gulf states. The fifth section studies the American behaviour towards Egypt.The fifth chapter envisions the future of the American policy towards the Eastern Arab countries. It is divided into four sections. The first one studies the political scene. The second deals with the scene (scenario) of the continuing of the present American policy. The third section suggests the change of this policy in away that enables the Arab countries to move in a space larger than that found in the scene of the continuing of the same policy discussed in the previous section. The fourth one work to intermingle the two previous scenes.

المستخلص: This study tackles a very important subject not for being the subject of debate and argument by the politicians and researchers , but it comes in period that witnesses an increasing calls and pressures for applying the democratic approach in ruling and these pressures come in time that many of the Third World countries submit to the despotic and dictatorial systems that raising democratic slogans without applying this approach .Here , to study the mechanism of modernization and developing these systems , We should study the role of civil society in these systems which represented by alleviating the burden thrown on the state through social , economic and cultural functions of these systems in addition to the political one .The study of the relationship of society with the political system , requires the search in the theoretical fram for main reason and that is development happened on the human science especially , political science . These developments led to the emergence of new concepts , some are disappeared and the other are developed and expanded which requires the study of these developments to understand the public frams of each concept and then apply it on the Arab situation and the study patterns . And this what we tried to do through studying the developments that happened on the political system . more over the rapid development of civil society in the western states and does it reach to our Arab societies .But , the existence of civil society in some our societies evoked an intellectual political debate for being one of the concepts that there is no agree on it's historical background in the Islamic political thought , and some definetly refuse it's existence not only in the Islamic Political thought , but also in the institutions of Arab contemporary state and they do assert that what is existing is traditional institutions took the form of civil society institutions in the west , but the indication is a mere traditional society that devotes the tribal fanatic and this clear in Jordan .This extremist opinion is considered denial of many efforts and activities of civil society institutions , because some could break the barrier of central despotisim of political system in order to explain his opinion and demands freely , as Egypt that has the pioneer role in this respect .The civil society characterized by effectiveness and motion which supported by great powers on purpose or non , these great powers promoted Egypt to appear in a nominal democracy not the real one , because they realize that the real democracy means the choice of Egypt society and this is appropriate with the regional Function of Egypt by the great powers .There is a fact hatcould not be deny that Egypt is considered institutions state , in spite of the domination of decision maker on the political life and puplic life in Egypt , and this domination is one of the problems of Arab states , Thus some systems justified it by using many means one of these is the belonging to the messenger of God ( pray and peace be upon him ) and this indeed what happened in the Jordanian political system which has a little freedom according freedom measurements . This political system a doped multiplicity as the Egyption … , but dealt with it cautiously and this matter left it . clear hard influence especially and civil society and the society generally on here the ability of civil society influence on the political system is very hard that we find some of it's indications in Egypt through its participation beside the government and private sector in commen development programs among the three seetors .After the explanation of this short brief about the subject significant , we must explain the structure of this subject which consisted of four chapter , introduction and conclusion .The first chapter tackles the conceptual fram of each civil and political society with all developments took place in this respect , more over studying the relationship between the two variables after the assumption that the strength and effectivness of the first political system is taken from the effectiveness of civil society ( second ) and revers is true .The second chapter studies the lawful , political , economic and social features through studying the accompanianed problematic of political parties action and the administration of head of state and king for the political process which reflected directly process whether in elections or through political process .While , the third chapter tackles of great interest the accompanianed problematic of concept using by enhance or limit concept borders and also the problematic of civil society existence in Egypt and Jordan but according to the Arab peculiarity and then the main characteristic of Egypt and Jordan .Where as , the fourth chapter tackles the influence of the political system on the civil society through affected the later by the first , but this will not abolish the influence of civil society on the political system , because of the need of political system for civil society or part of it's components to perform development programs and this is clear in Egypt . Finally , the conclusion represents a summary of the main ideas in this study and the conclusions that resulted from this study

المستخلص: Many scholars have dealt with the conflict of the regional powers and the major international powers in South - Asia Region on various aspects. The Indian military and nuclear capabilities are considered major fields of political studies. Such research is conducted in the framework of the Indian political system, the Indian relationship with the Arabic Gulf countries and the role of the rising powers in strategic balance. Indian international status in the 21st Century is the main issue of the current study. These academic efforts are aiming at defining the strategic capacities that India has, since its role in the Asian - region shows a kind of dominance. Moreover India is not only a regional rising power but has a distinctive international role with the ambition of occupying a permanent seat in the United Nations. The importance of the theme of the current study can be summed up as an attempt to approve the following questions : What are the Indian potencies?What are the main issues affecting the international status of India in the post cold war era?And finally, what are the future outcomes becoming out of the international status of India in the 21st Century? Indian technological, economic and social developments can be considered the fruits of its democratic political system. Despites all multi - cultured nature with language and religion varieties, India established a strong democracy. This affirms an effective foreign political act to state India as a regional and international dominant power in the 21st Century.The study sheds light on certain basic dimensions showing the Indian political will of having the most affective external political act in and outside its region. It is clear that India is promoting a future international status in the post cold war era. The problematic issue includes an investigation of all the internal and external variables affecting the status of India. Internal ones include various political, economic, military, as well as social strengthening potencies. While the external ones are either regional or international. The first are focused on the Indian role in a direct conflict with Pakistan and China as part of its continuing struggle for power over prominent strategic issues. But India has very distinctive cooperative relations with both The United States of America and Federal Russia. It also has a very large bilateral economic cooperation with both Japan and Australia. The future prospects more points for powerful Indian role in the 21st Century.The study falls into four chapters. Chapter One deals with the theoretical frame. It is an introduction divided into two sections. The first section includes the conceptual bases, presenting the terminology of status such as the role, function, and position. Moreover a definition of the regional and international systems and their targets. The second section deals with the main political, military economic and social objectives and principles of the Indian strategy. Chapter Two deals with International potencies of India which are geographic, social, political and economic. All these show the impact of internal and external factors on the rising international political role of India.Chapter Three restricts the scope of the study to the post cold war era. Chapter Four prospects a future perspective of the Indian international status in the 21st Century. This shows three scenes : the first is the Indian dominance, the second is the Indian - American coalition and partnership, and the third is the Indian part in international alliance. Consequently India has spiritual as well as materialistic capacities enable it to achieve a very influential international role. The current study proves the hypothesis that India's potencies whether internal or external increase its international role and make it more effective. The researcher has arrived at some conclusions and presents a review of the main points, they are mainly : 1) Indian ambition never stops on the regional bordered limitations. It is not considered only a regional dominant power. And it has far challenging economic, military and political prominence over its neighbour, Pakistan. But it is an international power making efforts to get a permanent seat in the United Nations. 2) Indian - Pakistani relation in the post cold war era has been a continuation of the pre cold war relations. It is based on mistrust, violence and instability heading to arm struggle rather than cooperation. This makes it a more strategic manipulator in the region. While the Indian - Chinese relation is colored with cooperation supported by many Governmental official visits on both sides. Though these countries are still competing for a more influential regional role. 3) There is a wide range of mutual interests between India and the United States of America. This is resulted in a strategic collision to achieve their interests in economy, military and politics. Moreover India has established good friendship with Russia on every aspect to serve their regional interests.4) India has an effective role in the Asia - Pacific region that is limited due to the regional strategic balance. Indian diplomacy has accomplished a lot to achieve mutual understanding and stability in the region. Its part in the Pacific - APEC Economic Forum has helped a great deal to insure Indian economic as well as political status.

المستخلص: The spying and intrusion operation had been widely spread to steal the information especially with the development of computer networks (like, Internet). To prevent this danger the development of a new technology called “digital information hiding” was developed in such a way that the intruder cannot notice the existence of secret information in the media.In this project an image steganograph system is introduced. The proposed system is based on using the affine transform to represent the blocks of the secret image in terms of the blocks of the cover image. Then, the least significant bits (LSB) insertion method is utilized to hide the quantized affine transform coefficients of the secret image in the cover image. Also in this research some block indexing methods are utilized to improve (i.e, speed up) the involved trials of affine mappings. Three systems (they are traditional IFS, IFS with symmetry predictions, and IFS with symmetry prediction and blocks indexing) have been established. They used to manage the way of selecting the suitable domain (cover) to represent the range (secret) block. The domain search operation will not need to make all isometric - block tests on each domain block. The best domain isometric state is assessed using the introduced isometric predictor; which is based on the moment status of the matched block. This will significantly reduce the matching time because only one match, instead of eight, will be tested to evaluate the IFS - similarity between any range and domain block. Also, a block indexing method is introduced to filter the domain blocks, and filter - in only those domain blocks that have similar block index with that of the mapped range block to be tested using IFS - matching.Some of the well known fidelity measures (like, MSE and PSNR) have been used to asses the quality of the reconstructed image. The conducted test results indicated that the proposed improvements have reduced the required hiding time down to 6.81 second (around 80 times in comparison with the traditional scheme) without making significant degradation in image quality

المستخلص: The study of the effect of some factors on the human is difficult and complex because of the lack of instruments for measuring eye efficiency.The human eye is an optical organ, its work is similar to the camera work, but the eye can not return the image which it makes, but the camer a can return. Producing high quality image by human optical system like other lens system is affected by many parameters, some of them are internal such as aberrations and age, pigmentation. Also human eyes suffer from some defects that effect the human eye image quality, some of these defects are : 1. Hypermetropia (Long sightedness)2. Myopia (short sightedness) 3. Some other defects The optical characteristics of human eye imaging system are studied quantitatively via experimental and computer modeling. Experimental work is carried out to study the effect of spatial frequencies, color and ages on image eye quality. Computer simulations models are carried out to study the limitations imposed by imaging in the human eye. Theselimitations include the diameter of pupil eye, the aberrations (astigmatism and spherical), age, and pigmentation of eye. These limitations are computed in terms of modulation transfer function (MTF).The results showed that MTF curves are suitable for determining image quality and the limitions effect on imaging system. Also result showed a coincidence between laboratory work and theortical calculation of MTF for age, pigmentation, pupil size and aberrations

The Al/c - Si/In, Al/c - Si/Ag and Al/c - Si/Au diodes heat treated at different annealing temperatures 303,373 and 473 K. The ohmic contact was aluminum with thickness of about 0.2 µm and the Schottky contacts were indium, silver and gold with thickness of (0.1, 0.2) µm under vacuum conditions of about 10 - 5 mbar. The effects of annealing temperatures and work functions have been studied by current - voltage and capacitance - voltage characteristics. The I - V characteristics showed that the rectification properties of all prepared diodes were improved with increasing the annealing temperature and the metal work functions (the ideality factor and the saturation current density decreased). The ideality factor (n), saturation current density (Js) and the barrier height (ΦB) were calculated using I - V plots with semilogarithmatic scale. The current - voltage characteristic of Al/c - Si/In, Al/c - Si/Ag and Al/c - Si/Au junctions showed that the current varies approximately exponentially with applied voltage and the junction was coinciding with recombination - tunneling model, the dark current decreases with increase of the thickness. Under illumination, the photocurrent increases and decreases with increase of annealing temperatures and thickness, respectively. The C - V characteristics of Al/c - Si/In and Al/c - Si/Ag diodes have been prepared at different thickness except Al/c - Si/Au at thickness equal to 0.2µm and annealing temperatures. The reverse bias capacitance was measured as a function of bias voltage at frequency 1 MHz; the capacitance decreases with increasing the reverse bias voltage, also with increasing of thickness and annealing temperatures. The built - in voltage (Vbi), barrier height (ΦB) and the carrier concentration (Na) were calculated using Mott - Schottky plot (C - 2 vs. V). The d.c. conductivity measurements using Arrhenius plot (lnσ=f(103/T)) showed that there are two activation energies Ea1,Ea2.The electrical activation energies increase with increasing annealing temperatures.

Then the array of each frame is transformed from the time domain into frequency domain using Fourier Transform (FT).To determine the characteristic frequency of the sound, a moving window technique was used, the size of that window is made proportional with the values of the tracked frequencies, the use of this adaptive window makes the difference with a previous research work conducted for the purpose, in that work a fixed - size window is used to track all characteristic frequencies.An algorithm was established to select the characteristic frequencies, this algorithm allocates the frequencies which satisfy the Doppler relation, beside that the tracked frequencies was chosen to be the most occurred frequencies in the power spectrum. Several sizes of the overlap windows have been tested to study the effect of window size on the accuracy of the determined radial velocity of the moving airplane. The obtained results have been compared with the corresponding results of non overlapped window.The accuracy of the results was assessed using two criterion, the first is the closeness of the curves of the determined radial velocities versus time for the case of overlapped and non - overlapped window; the closer curves indicate better results. The second used criteria is the Root Mean Square Error (RMSE), which is used to determine the linearity of the relationship between Doppler shift and characteristic frequencies, the least values of (RMSE) signify better results are obtained. Three values of the frame size have been tested; they are 0.1s, 0.15s and 0.2s. From the attained results it was found that the frame size 0.2s gives better results than the other tested sizes. In addition several values of window size have been tested; they are 0.01s, 0.03s and 0.05s, the best value is found 0.05s. Also the results indicated that the use of overlap window gives better results than the case of using non - overlap window.

المستخلص: Various compression methods have been proposed to achieve high compression ratios and high image qualities in low computation time relatively. In this research work a combined transform coding scheme was proposed, the adopted system utilize both Discrete Cosine Transform and Wavelet transform. The advantages of both transforms were taken into consideration to encode the image. First, the system transform the color components of the image from (RGB) to (YUV), the U and V bands are downsampled due to their poor spatial resolution, and then the wavelet transform is applied on each color band separately. Some spatial coding steps are applied on detail coefficients (like hierarchal uniform quantization, Run Length Encoding (RLE), shift coding) to gain more compression. The approximate coefficients are coded by using (DCT), uniform quantization, shift coding.Also, some analysis tests were done to study the performance of the established system, and the effects of the involved coding parameters on the system were investigated. The test results indicated that the proposed scheme give high compression ratio and good fidelity measures (MSE and PSNR). Moreover, the proposed scheme was found need 0.7 second to compress color images of size (256x256) without making significant degradation in image quality.

المستخلص: Acousto - optics science deals with the interaction between sound and light waves. Acousto - optic waves are most important in transferring signals through the communication systems, since modulating signals takes a great advantages in the field of communication engineering, bio - medical, laser beam deflection and laser intensity modulation.The aim of this work is to simulate the fundamentals of an Acousto - Optic Modulator. The simulation procedure is based on theoretical and computational relationships describing acousto - optic properties for three selected materials which are “Glass, Germanium, and Tellurium - Oxide”. Two computer programs have been written using “MATLAB” software, the first used to verify the normalized intensity of the diffracted orders versus peak phase delay using partial differential equation, while the second program is used to study the normalized intensity of the electric field versus time wave propagation and electro - magnetic wave propagation in x, y and z directions, using Finite Difference Time Domain. The results for Glass and Tellurium - Oxide materials shows that the periodic exchange of the normalized intensity between the zero and first orders becomes smaller as the interaction length D increase, this indicate that the higher orders may appear very clear in these materials. The results for the Glass material show that the normalized intensity of the electric field increases with increasing electromagnetic wave propagation in x, y and z directions.

After cooling or removing the stress, they have the ability to remember their previous structure and return to it.The concern of this study is on the thermal properties of NiTi thin film and its substrate as an attempt to understand the behavior occurring in the thin film slide represented by breaking it at certain values of voltage, current and substrate temperature (Ts). We have selected NiTi alloy because of its important medical and industrial applications. Thermal conductivity and heat capacity of NiTi thin film have been calculated theoretically and the thermal conductivity and heat capacity of glass substrate are measured experimentally. The cause of breaking in the thin film slide is the result of large difference in the thermal properties represented by thermal conductivity and heat capacity between the NiTi thin film and glass substrate. This is because the glass can not bear the high amount of heating energy resulting during the phase transformation process between Austenite and Martensite which exerts on the thin film slide

المستخلص: The main purpose of this work can be classified into four objectives. These are summarized as follows : The first objective, is to classify the one - dimensional integral inequalities.The second objective, is to find explicit bounds for the unknown function that appeared in special types of the one - dimensional Volterra linear and non - linear integral inequalities.The third objective, is to classify the ordinary integro - differential inequalities.The fourth objective, is to give explicit bounds for the unknown function that appeared in special types of the ordinary Volterra first order and second order linear and non - linear integro - differential inequalities.
