Power conditioning of thermoelectric generated power using dc-dc converters: A case study of a boost converter
(University of Nottingham, 1930)The near exhaustion of non renewable energy resources such as fossil fuels followed by disastrous climatic changes have alerted the world to invest in alternative energy sources. Thermoelectric (TE) technology is responsible ... -
A microcomputer-controlled solid-state dark adaptometer
(Behavior Research Methods & Instrumentatio, 1981)A low-cost microprocessor-controlled light-emitting diode (LED) dark adaptometer is described. The apparent intensities of red and green stimuli are controlled by changing the duty cycles of LED display elements which ... -
Low-Temperature Migration of Silicon in Metal Films on Silicon Substrates Studied by Backscattering Techniques
(Journal of Vacuum Science and Technology, 2000)The backscattering method using 2-MeV4He+ ions is employed to obtain microscopic information about solid-solid reaction of Si with thin layers (200∼4000 Å) of Au, Ag, and Al which are vacuum evaporated onto Si crystal ... -
Solution of large-scale weighted least-squares problems
(Numerical linear algebra with applications, 2002)A sequence of least-squares problems of the form miny G1=2(ATy−h) 2, where G is an n×n positive definite diagonal weight matrix, and A an m×n (m6n) sparse matrix with some dense columns; has many applications in linear ... -
Defining visualization operations for temporal cartographic animation design
(International journal of applied earth observation and geoinformation, 2002)Cartographic animation has emerged as a potentially effective visualization technique that has an intuitive power in representing dynamic geographical phenomena through its ability to show interrelations amongst geospatial ... -
Formation of silicon oxide over gold layers on silicon substrates
(Journal of Applied Physics, 2003)When a single‐crystal substrate of silicon is covered with evaporated gold and heated at relatively low temperatures (100–300°C) in an oxidizing atmosphere, a silicon‐dioxide layer is readily formed over the gold layer. ... -
Training for Improved Decentralized Service Delivery – A case study from Uganda
(WEDC, Loughborough University, 2004)The introduction of decentralization and decentralized service delivery in Uganda placed an increased demand for qualified personnel at the districts and lower levels. Despite this, there were no efforts in the past to ... -
Cryptosporidiosis and Microsporidiosis in Ugandan Children with Persistent Diarrhea with and Without Concurrent
(The American Society of Tropical Medicine and Hygiene, 2005)Cryptosporidium spp. and Enterocytozoon bieneusi are enteric pathogens that have emerged as significant causes of persistent diarrhea (PD) in immunologically compromised individuals particularly in association with HIV/ ... -
Towards A Sanitation Selection Algorithm For Enhancing Decentralized Service Delivery
(WEDC, Loughborough University, 2006)In Uganda, sanitation coverage is estimated at 53% and 39% for urban and rural areas respectively. The national coverage is 41%. Lack of proper sanitation potentially leads to environmental health problems, which in many ... -
MOVE: A Multi-level Ontology-based Visualization and Exploration framework for genomic networks
(Silico Biology, 2006)Among the various research areas that comprise bioinformatics, systems biology is gaining increasing attention. An important goal of systems biology is the unraveling of dynamic interactions between components of living ... -
Integration of Information Communication Technologies (Icts) in The Distance Education Bachelor of Education Programme, Makerere University, Uganda
(Turkish Online Journal of Distance Education, 2006)This article reports on the problems experienced by the Department of Distance Education, Makerere University, Uganda with the B.Ed. (External) programme with specific reference to the technology needs and expectations ... -
Detection of Filamentous Bulking Problems: Developing an Image Analysis System for Sludge Composition Monitoring
(Microscopy and Microanalysis, 2007)This article describes a fully automatic image analysis procedure for fast and reliable characterization of the activated sludge composition, that is, the floc and filament features. The algorithms developed for each of ... -
Frequency and site mapping of HIV-1/SIVcpz, HIV- 2/SIVsmm and other SIV gene sequence cleavage by various bacteria restriction enzymes: Precursors for a novel HIV inhibitory product
(African Journal of Biotechnology, 2007)Resistance, toxicity and virologic failure have underlined the need to develop new HIV inhibitory products. Base on the natural bacteria “restriction modification system” antiviral immune model, we set out to analyze the ... -
A System Dynamics Tool for Higher Education Funding and Quality Policy Analysis
(International Conference of the System Dynamics Society, 2008)Conceptually, the level of funding of higher education activities is directly proportional to its strategic directions/implementations and hence quality. In developing countries, these dependencies are far from straightforward ... -
Repeatable Collaboration Processes for Mature Organizational Policy Making
(Springer, Berlin, Heidelberg., 2008)Organizational policy making processes are complex processes in which many people are involved. Very often the results of these processes are not what the different stakeholders intended. Since policies play a major role ... -
Incident Response Planning Using Collaboration Engineering Process Development and Validation
(Journal of Information System Security, 2008)Many organizations have plans for incident response strategies as; An initial version of this research was presented at the Inaugural Workshop on Information Security and Assurance (WISA): Special Interest Group on Information ... -
Solid-State Deuterium NMR Studies Reveal μs-ns Motions in the HIV-1 TAR RNA Recognition Site
(Journal of the American Chemical Society, 2008)Solution and solid-state NMR measurements were used together to examine motion in three sites in the HIV-1 TAR RNA. We wished to investigate the dynamics facilitating the conformational rearrangements the TAR RNA must ... -
Experimental investigation of positional accuracy for UHF partial discharge location
(IEEE., 2008)UHF methods for locating partial discharges (PD) in power transformers are under development and are increasingly being applied in the field. Due to the complexity and variation of internal structures in power transformers, ... -
Effect of processing technique on energy density and viscosity of cooking banana: implication for weaning foods in Uganda
(International journal of food science & technology, 2008)The type and quality of weaning food plays a vital role in the growth and development of children. The high rates of malnutrition reported in banana consuming areas of Uganda reveal the bulkiness and high viscosity of ... -
On Systematic Design of Service-Oriented Architectures
(2008)We present a systematic means of designing serviceoriented systems. Because services are developed independently, with no prior knowledge about each other, there is only a limited possibility that such services use similar ...
