Taschenbuch. Zustand: Neu. Neuware -The importance of the piece of paper cannot be ignored towards facilitating communication between people. People generally store important information by writing on paper for retrieving at a later stage. Paper is still a convenient and feasible way of storing data in the form of handwritten script or printed text. A huge amount of historical data is also written on papers. So, there is a great demand to digitize all these paper documents so that the people all over the world can access these important sources of knowledge. Many researchers are attempting to simulate intelligent behavior and mimic the human brain¿s ability to read and recognize the handwritten or printed characters from the paper surface so that the computer can understand this script and process the data. For this purpose, the image of handwritten text is extracted, preprocessed and segmented into individual characters and are recognized by a neural network classifier. The automated processing of handwritten material optimizes the data processing speed as compared to manual processing and delivers very high recognition accuracy in least cost.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 84 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -There is a particular conflict from which all conflicts stem from. The mother of conflicts initiates and sustains conflict, with other forms of conflict being employed as an excuse or to further the underlying interests of parties to a conflict. With Africa hosting 40 percent of the 27 violent conflicts in the world as of the dawn of the twentieth century, a major focus on Africa would be at the fore to determine the reason for the high spate of conflict on the continent. The issues of nation-building and development would also be discussed to understand how they connect to the mother of conflicts and how they influence one another in the progress or otherwise of a country. This work, which is a sequel to my other works on ethnicity, religion, and nation building and development reveals why most African countries cannot be called a nation, and the major factor that hinders nationhood. This particular study serves as a concluding part to the previous works. Without a knowledge of what the mother of conflict is, and how it is being manipulated by state and non-state actors in furthering their interests, nation-building and development would be difficult to attain in Africa.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 68 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The 1950s and 1960s were decades most African countries attained their independence and were expected to usher in Africäs prosperity and development. However, with over sixty years after the end of the colonial era, Africa remains the continent with the highest rate of poverty, illiteracy, and infant mortality. A major contributory factor to this rating has been the many cases of violent conflicts and civil unrest which hinder the development of many African countries. These conflicts take various forms such as ethnic conflicts, religious conflicts, resource conflicts, labour unrest, and other forms of conflicts. The result of this instability has been the loss of lives and properties, underdevelopment, further distrust among warring parties, disunity, and then more conflict. To stem the tide of incessant conflict and unrest on the African continent, scholars and political leaders advocated for the application of Nation Building in various African countries. This proposed solution resulted from the fact that the African continent is characterized by a diverse demography. How has the nation-building process fared This and questions on development are analyzed in this study.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 68 pp. Englisch.
