    Exponential Estimates in Retarded Functional Differential Equations
    (Addis Ababa University, 2012-02-02) Tadesse Dereje; Abdi Tadesse (PhD)
    So far, many things were said about differential equations without time delay, the so called ordinary differential equations or partial differential equations and their solutions. Different techniques have been used to show the existence and uniqueness of the solution of initial value problem of these equations. Since time delay occurs naturally in just about every interaction of the real world, here in this project report we treat some differential equations with time delay, the so called linear functional differential equations or linear differential difference equations in general and for these equations, a complete theory can be developed using very basic tools. The project serves as an introduction to the more general types of differential difference equations. It also is intended to bring out the roles of the characteristic equation and Laplace transform to determine the solution of linear differential difference equations and to emphasize some of the differences between retarded and neutral equations.

    Improving Public Service Delivery: the Case of Land Development and Management Office in Nifas Silk Lafto Sub-City
    (Addis Ababa University, 2017-05) Tadesse Dereje; Berhanu Elias
    This study was intended to assess the performance of land management service delivery of Nifas Silk Lafto Sub-City. For African countries, there is strong force in proper urban management which better achieve the increasing need for efficient and effective delivery of land administration services to protect the interest and security of urban citizens. As urban land administration is a comprehensive and important part of public service delivery, the concept of quality service gets worthwhile attentions. Therefore, this study assessed the land management service delivery performances in Nifas Silk Lafto sub city. The study is both descriptive and explanatory in its type. This research employed both qualitative and quantitative research methods to draw samples, collect data, analyse and interpret data. To portray sample from target population (citizens residue in NSL sub-city, land management office employees, officers and managers), the researcher adopted both simple random sampling and purposive sampling techniques. In the current land administration of Nifas Silk Lafto sub-city, customers have to consult various organizations/departments to get the service done. The title service delivery system is not only time taking but also expensive. As a result the urban poor is being pushed away not to use the service. Thus, these situations have created gaps between expectation of citizens and land administration service provided by the sub city land administration organization as more than half of the respondents did not receive efficient, equitable and accountable land services as per their expectations. Case study method, supporting literature review and hypothetical factors for quality service delivery adopted by World Bank (2005) and SERVQUAL Service Quality Model have been used as guidelines for the study. The case study has used 106 customer respondents and 30 employees and 6 anagers as primary data source through questionnaires and interviews. The analysis of the data and information collected from the field work found out the performance and challenges of land service delivery as: inconsistency in land related legislations, inadequate resources and technical capabilities, not all lands are titled, lack of skilled and qualified man power, lack of public awareness, unclear land ownership. Based on the identified findings, conclusions are drawn and possible recommendations are made. Key Words:Land Management, Land Administration and Cadastral Map
