    Assessment of reactive power compensation using distributed generation
    (Makerere University, 2014) Tegule, Stephen
    The provision of reactive power is a means of improving the voltage profile for a power grid. In this research, the use of distributed generation as a source of reactive power for voltage improvement is demonstrated. A solar PV system can be used as a source of reactive power that is produced by the inverter. To justify its importance, the system is compared with conventional methods that include; Static shunt capacitors, Static series capacitors, Synchronous compensators, Static VAr compensators, and STATCOMs. Kibuku town council is used as a case study. To implement this project, the case study is modeled and simulated to determine the available voltage profiles. The conventional methods are modeled to improve the voltage profile and a grid-connected solar PV system is also modeled. These two are simulated for voltage improvement and the results obtained which are voltage outputs are compared. From these results, the need for distributed generation as a means of reactive power compensation is justified.

    ( 2014-05-02) ASIIMWE, Mwesigye
    The research was aimed at assessing the impact of change in the use of buildings in Kampala. The objectives of the research are described in chapter one which included identifying the most common changes made on buildings, the reasons for change in use, the modifications done on the buildings and the problems caused by the change in use of buildings. Chapter two of the research looked at the literature review of the study which is an evaluative report of information found in the literature related to the area of study. Chapter three looked at the methodology used to collect data for the study. The methods used included photography, use of questionnaires and interviews. Chapter four of the report presents the findings of the research and analysis. The research findings were presented using graphs, pie charts and in text Civil works involving demolition and construction of walls, placement of furniture and fittings, works on finishes and changes to the landscape were done. Most of the businesses setup their premises in various locations within the city. This has led to the over population of the city leading to increased traffic ,congestion, increased sound pollution due to vehicular and pedestrian activities, increased cost of renting space in office buildings and limited parking space. Due to the above reasons, a number of businesses choose to relocate to the outskirts of the city which were majorly comprised of residential communities. As a result of this shift, some residential communities were completely over taken by commercial activities which prompted the city authorities to rezone these regions as commercial areas. In carrying out the study, the organization of the building before and after the change in use were both considered. The various ways to resolve the problems identified in the research are described in chapter five consists of the conclusions and recommendations.

    (Makerere University, 2014-05-19) Isabirye, Benard
    This focuses on the application and decoration of car dash board with hand woven products. The study was carried out around Ndeeba and Najjanankumbi were I carried out an informal interview from two correspondents with the help of an interview guide. However the interview helped me get what I wanted in form of people’s view and attitude towards the hand woven fabrics in relation to power woven fabrics. Therefore opportunity was created for hand woven products for car interior decoration on parts like the dash board. I hope that the study will create environment awareness to weaving students; help crafts men to expand their market and production, future reference for the future researchers, provide a room for the clients to enjoy their tastes and preferences through the direct contact with the artist/designer and also shall provide the researcher with a basic stand towards the formulation of new advancements of incorporating natural fabrics in relation to power woven products in car interior designing.

    The rapid rise of abstract painting around Kampala.
    ( 2014-05-19) Kwizera, Adrian Baggio
    Abstract art is a form of visual language of form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Paintings mainly done nowadays are more of abstract. The reason is that people nowadays express their feeling in abstraction. The researcher’s area of study was mainly town based in places like Central Kampala, Ntinda and Kamwokya. The researcher goes ahead to tell all painters that they should also do a little of reality as the legends in painting put it. With this, it will bring back the beauty of painting hence making the paintings master pieces and also National treasures.

    Assessing Agricultural drought vulnerability based on a Compsite index. A case study of Uganda .
    ( 2015-07-03) Ssekabere, Godfrey
    In the recent years, Uganda has been experiencing drought incidences which are increasing in the intensity and frequency due to natural resource degradation, population pressure, development and climate change. Thousands of people have been affected, with massive displacement occurring (GOU, 2007). There is growing demand for spatially explicit information among stakeholders across public and private institutions regarding vulnerability to Agricultural Drought at the local scale for implementation of long term drought management measures. This study was conducted over all districts in Uganda, to determine the Agricultural drought indicative parameters and to determine the spatial variability of the Agricultural Drought in the entire country and, thereby identify vulnerable hotspots. A biophysical and socio-economic indicator based integrated vulnerability assessment technique was used to map Agricultural Drought vulnerability. Indicators were generated and analyzed under three components of vulnerability, namely exposure, susceptibility and adaptive capacity; and finally aggregated into a single vulnerability index. The values of all indicators were normalized by considering their functional relationship with vulnerability, and factor analysis was then used to assign weights to all indicators. The Agricultural Drought vulnerability index (ADVI) was finally determined from the weighted sum of all indicators and mapped over the entire country. The districts in the northern region and some parts of north-eastern region had high to extreme vulnerability to Agricultural drought; while districts in the south- western part of the country were the least vulnerable. The rest of the districts had mild and moderate vulnerability to Agricultural Drought. This study shows that vulnerability mapping is crucial in determining the varying degrees of vulnerability of different localities, and generating information that can help researchers, policy makers, private and public institutions in formulating site-specific adaptation strategies and prioritizing adaptation investments to the most

    (Makerere University, 2015-07-13) Matovu, Anthony
    There are different GPS positioning techniques that are currently being used by Sur. eyor one of which is the Auto base and No Auto Base Technique that are embedded in the GPS machines. The CHC GPS machine has a capability of site calibration not common to all other GPS machines like Leica, so instead of setting up a GPS on a control, it can be set up anyw here without even centering itand a reading made on the control and site calibration is carried out. The general objective of the study was to compare the accuracy of Auto Base and no Auto Base RTK positioning techniques. The specific objectives included; fixing points using Auto base and No Auto base RTK techniques, to evaluate the accuracy of the Auto base RTK technique. The researcher collected data from 20 carefully selected points within in Mukono District. Data was collected using GPS CHC equipment. The researcher therefore concluded that there are 20 points that were successfully fixed by both techniques. The mean and standard deviations of the change in Eastings, Northings, Heights and the Linear shift were also determined making the accuracy evaluation of the autobase RTK technique a success. These were illustrated in the table showing a summary of the analysis.

    Interlocking Stabilised Soil Blocks: An evaluation of the use of the building material in low-cost housing in Uganda. A study of the Dry Stacked Method.
    (Makerere University, 2015-11-17) Atuhwera, Morris
    Luweero district has had a history of war that left part of the region devastated. The housing deficit that arose as a result has led to challenge of informal growth marked by structures that are constructed with semi-permanent or temporary materials as the majority of residents cannot afford using modern building materials. This has resulted to the depletion of the natural vegetation in the quest of acquiring/making building materials that are socially accepted. The project proposal introduces interlocking stabilised soil blocks (ISSBs) as a means of providing low cost housing that is eco-friendly. The study sought to evaluate the extent to which low cost housing can be achieved by using of interlocking stabilised soil blocks as the building material. Studies were done on structures constructed using ISSBs on projects within the central region in Nansana, Wakiso district and Luweero district. The variables under investigation included affordability, eco-friendliness, aesthetic and durability qualities, psychological aspects of the building material, social influences and cultural beliefs. The data collected was analysed both qualitatively and quantitatively, and represented using illustrations/sketches, graphs and charts.

    Prison Architecture and its Relevance in Rehabilitation.
    ( 2015-12) Rukundo, Josephat
    No human soul is a culprit by birth. Unfavourable circumstances, acute poverty, illiteracy and abuse forces them to take terribly actions. The aim of the prison is not to only punish the convicted felons but also rehabilitation them and to Prepare them to live a better honest and decent life. These prisoners have great potential if they are rehabilitated in an effective manner, it helps in rebuilding the human character by insulin ethics , morality and self esteem. This dissertation studies the purpose of prisons and how they can be designed to help in reforming the lives of inmates. The society stigma that gets attached to a person who has been to prison, bounds him/her outcast from Family and society, consequently he/she is left to survive on his/her own. Furthermore this research studies the challenges faced in establishing rehabilitative parameters in prison design. My case studies are Luzira and Katojo prisons in central and western Uganda respectively and North Branch Correction Institute Arizona located in Maryland, America

    Investigating the efficacy of Aloevera as an alternative Coagulant and Disinfectant in water treatment.
    ( 2015-12-12) Byaba, Benard
    In conventional drinking water treatment, the coagulation processes are applied to destabilize the surface charges of colloids and enhance agglomeration (flocculation). Proper coagulation is essential for good filtration performance and disinfection by-product control. Disinfection processes are also carried out at water treatment plants in order to improve the microbiological quality of drinking water. Some chemicals are used in these processes and these are aluminium and iron salts for coagulation and chlorine for disinfection. However these chemicals are associated with a few setbacks, they are both expensive and not locally available. The raw water source was River Rwizi in Mbarara, it was analysed for turbidity, pH, color, electric conductivity, and microbiological quality which are fundamentals for drinking water treatment. The pH of the raw water sample was 6.68, turbidity; 96.5 NTU, apparent colour; 963 PtCo, true colour; 884.7 PtCo, electrical conductivity; 78 μS/cm. These values generally did not meet both the National portable and WHO standards for drinking water quality. Jar tests were carried to determine the performance of the aloe extract as a primary coagulant, and flocculant and coagulant aid. The performance of alum was also determined for comparison. To investigate the suitability of aloe vera as a disinfectant, raw water samples were treated with aloe vera extract. Parallel tests were done were done with High test sodium hypochlorite. The aloe vera extract proved to be a poor primary coagulant. Aloe had a 51% removal of turbidity at 70mg/l, whereas alum had a removal percentage of 85% at the same dosage. Aloe performed poorer with regards to true colour removal where it had a 35% removal of true colour at 70mg/l whereas alum had a 100% removal of true colour at this same dosage. Aloe Vera presented lower disinfection activity than chlorine.

    Establishing a link between spring water quality and waterborne diseases occurrence in Lubigi Catchment (Bwaise, Nabweru and Kawala) Kampala Uganda
    (Makerere University, 2016-06) Mubiru, Steven Remmy
    The research study was aimed at assessing whether there is a clear link between spring water quality and water borne disease occurrence in Lubigi catchment. Previous studies have shown that 1.8 billion people worldwide drink water that is faecally contaminated. Densely populated areas experience water pollution and heavy disease burden. Most people rely on groundwater to meet their water demand. Annually, water borne diseases kill about 3.4 million people worldwide. Uganda has had epidemics of water-borne diseases including cholera and typhoid cases. The following activities were carried out; field visits, calibration of instruments, sample collection and handling, in-situ measurements, laboratory measurements, selection of springs and frequency of sampling, household questionnaires, key informant interviews, focus group discussions, and epidemiological surveillance data collection. The results showed that the water quality is generally not good but it is worse in the wet season. During the wet season is also when the water borne disease occurrence is more with more cases registered in the medical centres. There is a strong relationship between the water borne diseases and spring water quality. Ensure proper record keeping and improved epidemiological surveillance system, for effective monitoring of diseases in the study area. The spring water should be monitored and if possible improve the water quality because a great number if people still rely on them. It is also a cheaper source of water.

    An investigation into the barriers and facilitators of walkability in the eastern part of Kampala Central Business District
    (Makerere University, 2017) Katureebe, Apollo
    Walking is seemingly a forgotten mode of transport and consequently few analytical techniques are available to help practitioners identify low standard walking environments. Providing accessibility to the transport network for all groups of the community is vitally important. For most groups of the community severed from easy accessibility i.e young, old and mobility impaired, walking provides the first, last and often the only mode of transport. Other functions that walking aids include community involvement, health, and recreation are all affected by low quality walking environments. In Uganda, walking is the oldest and basic form of transportation as it provides mobility to over 70 percent of the population (Ministry of transport), especially the poor who are unable to meet other alternatives, however the transport infrastructures are more biased to motorized traffic rather than part of the public realm for pedestrian experience. This calls for an investigation into the barriers and facilitators of walkability. The general objective of the study was to assess the barriers and facilitators of walkability in the Eastern part of Kampala CBD. The specific objectives included; investigating attitude and perception of people towards walking, identifying the importance of walking as a mode of transport and developing strategies and recommendations to enhance walkability. The researcher collected data from 47 respondents of whom 2 were purposively selected and 45 were randomly selected from pedestrians along the three networks of Jinja road, Wampewo avenue and Old port bell road. Data was collected using a combination of in-depth interviews and questionnaires as well as analysis of secondary data sources. The study concludes that walking should be given much attention as another mode of transport which has to be incorporated in the resultant designs since it consumes no fuel, very cheap, helps to promote physical exercises and above all helps to reduce traffic congestion in the city.
