Mathematical Models for Influenza a Virus and Pneumococcus: Within-Host and Between-Host Infection
Kamugisha, Mbabazi, Fulgensia
Infectious diseases have become problematic throughout the world, threatening
individuals who come into contact with pathogens responsible for transmitting
diseases. Pneumoccocal pneumonia, a secondary bacterial infection follows an
influenza A infection, responsible for morbidity and mortality in children, elderly
and immuno–comprised groups. The aims of this Thesis are to; develop a mathematical
model for within–host co–infection of influenza A virus and pneumococcus,
model between–host pneumococcal pneumonia in order to determine the effect
of time delays due to latency and seeking medical care, and study the effect of
antibiotic resistance awareness and saturated treatment in the control of pneumococcal
pneumonia. Analysis of the stability of steady states of influenza A virus
and pneumococcal co–infection, pnemococcal pneumonia with time delays and
antibiotic resistance awareness is done. The graph theoretic method, combined
linear and quadratic Lyapunov functions, Goh–Voltera Lyapunov function are
used to get suitable Lyapunov functions for global stability of steady states. The
results show that the endemic equilibrium of pneumococcal pneumonia is locally
stable without delays and stable if the delays are under conditions. The results
suggest that as the respective delays exceed some critical value past the endemic
equilibrium, the system loses stability and yields Hopf–bifurcation. The results
of influenza A virus and pneumococcal co–infection show that, there exist a
biologically important steady state where the two pathogens of unequal strength
co–exist and replace each other in the epithelial cell population when the pathogen
fitness for each infection exceeds unity. The impact of influenza A virus onto
pneumococcus and vice–versa yields a bifurcation state. The results show that,
the presence of antibiotic resistance awareness and treatment during the spread
of pneumococcal pneumonia drastically reduces the basic reproduction number
R0 to less than unity, hence the disease could be eradicated.

Police, in the quest to keep law and order, handles issues manually. Once an issue is forwarded, it is recorded in the personal books that act as files for each individual; this is then captured in the central store which in all cases is a black book. Calls are then made using radio calls to make reports and a number of communications to other police stations. This process is time consuming, leads to data loss and does not maintain data integrity and security. A service desk will address all of the above mentioned problems. The researchers set to develop an Intranet Based Police Service Desk for Uganda Police to solve the problem above. This was in the effort to provide efficiency in police undertakings. In order to get information about the existing system, questionnaires, interviews and observations were conducted with top police officials to get a clear picture of how police operates, get user and system requirements needed for the proposed system. The Records Manager Mr. Okeleng John at the Police headquarters in Kampala and the District Police Commander (DPC) of Wandegeya Police Station were the main respondents during the study. Data Flow Diagrams, Entity Relationship Diagrams and context diagrams were the tools used in the design of the system. A database was developed to enhance dynamic interactivity and information storage of captured information. A Website was also developed to act as a user interface and sample screen shots of the interfaces were presented as well as reports generated from the system. In a nutshell, basing on the findings of the study like increased efficiency in Police operations, increased accessibility to information, improved communication, teamwork, enhanced focus and creation of a proactive approach to service provision, it is therefore advisable that Police implements the Intranet Based Police Service Desk.

Goal Models Vs Five Forces Models: A Comparative Study of Strategic Analyses
Kasozi Musanje, Joseph Brian
The performance of an enterprise is determined by its strategic objectives, and the
strategic plan it adopts through some form of strategic analysis in order to meet
these objectives. However, strategic analysis is currently only supported through
unsystematic and informal processes such as SWOT analysis and the Five Forces
Model. This thesis proposes conceptual goal modeling as a systematic approach
to strategic analysis and shows through a comparative study how this analysis
can be conducted for a Goal Model and the Five Forces Model. The study is
conducted through a case study adopted from the literature.
