Control theory is an area of applied mathematics that deals with principles,laws, and desirernof dynamic systems.rnOptimal control problems are generalized form of variation problems. A very importantrntool in variational calculus is the notion of Gateaux-di_erentiabilty.It is the basis of...
Background: adolescence is a continuum of physical, cognitive, behavioral and psychosocialrnchange that is characterized by increasing levels of individual autonomy, a growing sense ofrnidentity and self-esteem and progressive independence from adults.

The concept of Boolean like rings is originally due to A.L.Foster, inrn1946. Later, in 1982, V. Swaminathan has extensively studied the geometryrnof Boolean like rings. Recently in 2011, Venkateswarlu et al introducedrnthe notion of Boolean like semirings by generalizing the conceptrnof Boolean...
BackgroundrnDespite the increased focus on pain management programs and the development of newrnstandards for pain assessment, postoperative pain (POP) remains a concern for patients.rnObjective: To assess adult postoperative pain management practice amongrnnursesrnworking in Addis Ababa public...
The purpose of the study was to investigate Neural Networks in general and RecurrentrnNeural Network in particular. The investigation was to construct a model that shows therncomplex data processing of these Neural Networks and their functions in a simple way byrnusing Artificial Neural Networks....
Background: Many people have some type of altered cell growth such as moles and skin tag.rnMost of altered cell growth are harmless (benign) and do not require intervention. Malignant cellrngrowth or cancer, however, is serious and, without intervention, leads to death. Even though,rnproviding care...
Foreign Direct Investment (FDI) plays an important role as an engine of employment,rntechnological development, productivity enhancement, economic intensification, andrnmore importantly, as an instrument of technology transfer, specially from developed torndeveloping countries. The Government of...
Ordered trees are trees with a distinguished vertex called the root where the children of each internal vertex are linearly ordered. K-trees generalize ordered trees in the sense that ordered trees are 2-trees in which edges between nodes are drawn as double edges. A class of numbers are introduced...
This paper assesses the implications of regulatory policy namely, NBE billsrnpurchase directive, on the development of private commercial banks in Ethiopia.rnMixed research approaches and descriptive research type were employed.rnAccordingly, research questions were approached via research tools...
Since Riemann, there have been a great number of generalizations of the Riemannrnzeta function. Of particular interest is the hypergeometric zeta functions a generalizationrndue to Hassen and Nguyen that satisfies many of the same properties as thernclassical Riemann zeta function. In this...
Lemongrass is perennial herb which has been cultivating in Ethiopia and known as tej-sar which has been using to decorate the house rather than for perfume application. The objective of this study was to develop a perfume at optimum extraction point using steam distillation from tej-sar (Cymbopogon...
For several decades algebraic method have been successfully used in automated deduction inrnGeometry objects in Euclidean geometry are relations between them are expressed asrnpolynomials and algebraic method e.g.Groebner bases are used over that set of polynomialsrnwe describe aformalization of an...
The purpose of this study was to assess the role of CSOs in the development ofrndemocratic political culture in Ethiopia. Descriptive survey method was used to attainrnthe objective of the study. The study was conducted by using 27 CSOs engaged in therndevelopment of democratic political culture of...
As a by-product of biodiesel production, glycerol has now become an abundant and cheap source of carbon. Conversion of this glycerol to higher value products will increase the economic viability of the biodiesel production process. The aim of this project work was to produce Bio-ethanol using crud...
The aim of this project focus on Banach's contraction principle for finding the exis-rntence and uniqueness of fixed point. And a sequence of iterative Tn (composing ofrnT with itself n times) converges to this fixed...

To this end, the study employed mixedrnapproach, which...
From an algebraic point of view, semirings provide the most natural gener- alizations ofrnthe theory of rings. In this paper, the ring theoretic results of concerning the primaryrnideals and their radicals to noncommutative semir- ings are generalized. The derivedrnresults are further carried over...
After a detail demonstration of AES (Advanced Encryption Standard) , we explainedrnthe procedure of changing the key-recovery problem of AES-128 to a zero dimensionalrnideal from a single plain text /cipher text pair. Followed by explaining a method,rnBuchberger's Algorithm for computing a Groebner...
