The Particle Swarm Optimization algorithm has been empirically shown to perform well on many optimization problems. However, it may easily get trapped in a local optimum (premature convergence) when solving complex multimodal ...
This thesis presents the study of a multichoice multiobjective transportation problem (MCMOTP)
when at least one of the objectives has multichoice coefficient and multiple aspiration levels to
achieve, and the parameters ...
Shigellosis is one of the most common diarrhea diseases causing lots of morbidity and mortality
in developing countries. Shigellosis can occur at any age but it has particularly violence for
babies and children. ...
In this thesis two heterogeneous servers Markovian queue with server states dependent
customers’ impatience (balking and reneging), synchronous vacations and N-Policy on
slow server is examined. Whenever a customer arrives ...
In this project work nonlinear min-max optimization problems subject to inequality
constraints were considered. The objective of this project work was to find an approximate
solution of min-max optimization problems ...
The main objective of this project is to study exponentially fitted finite difference method,
develop stable, convergent and demonstrate the efficient numerical method for solving
singularly perturbed differential ...
Logistic equations are mostly used to model real life problems. However it is known that in
general, these equations do not have analytic solution. For that reason, researchers have tried
to solve these problems by ...
In this thesis work, we formulated a deterministic mathematical model of Typhoid fever to describe
the transmission dynamics of Typhoid fever and for the purpose of studying the effects of drug
resistance on controlling ...

The main purpose of this study was to investigate the implementation of inquiry based learning
strategy to enhance grade 10 students’ problem solving skills inquadratic inequalities. The study
was conducted in Degolo ...
Generating Pareto front of multi-objective optimization problems is a difficult task, it needs
to simultaneously optimize multiple conflicting objectives. This thesis improves the crowding
distance operator of the NSGA-II ...
The main purpose of this thesis was to assess the factors that hinder visually and auditory impaired students in learning mathematics of the three schools of Debre Markos town. The study was conducted at three Debre Markos ...
The principal purpose of this thesis is to extend results from reverse derivation prime rings to generalized
reverse derivations on prime near rings in the setting of semigroup ideals and discuss conditions under
which ...
In this thesis a deterministic mathematical model for COVID-19 with double dose vac-
cination is developed and analyzed by using Modi ed Adomian Decomposition Method
(MADM). To conduct the objective, secondary recent ...
In this thesis, a new deterministic model for the Dengue disease is developed and
analyzed with the homotopy perturbation transform method. The model comprises
six compartments namely human population susceptible class ...
Bacterial meningitis caused by Neisseria meningitides (Nm) is of particular concern due to its
potential to cause large epidemics, causing severe brain damage and fatality. Meningitis can
occur at any age but it has ...

This study sought to determine the effect of the problem-solving approach and processes to
reduce student`s exam anxiety and improve self-efficacy on the academic performance in
Mathematics in twelve’s grade of preparatory ...
The main purpose of this project is to obtain the numerical solution of linear volterra
and fredholm integral equations by using Haar wavelet collocation method. Specifically, a
numerical solution of the second kind of ...
In this thesis an infinite capacity single server Markovian queuing system with single
working vacation, reneging and retention of reneged customers is examined. Whenever
a customer arrives at the system, it activates ...
