    Sandy Stevens Tickodri-Togboa, Izael Pereira Da Silva - Electrification and energy provision in rural areasThis Paper presents the results of technical, financial, environmental and management feasibility studies into the provision of reliable, sustainable and environmentally-friendly supply of electricity to the north-west corner of Uganda, called the West Nile Region – a region that is highly populated by comparison with the average population densities of the country and whose location is of both strategic and economic importance in that it serves as a gateway to the Democratic Republic of Congo and the Central African Republic in the west and to the south of Sudan in the north. The study examines various possible options for supply of electricity to the region and concludes that the optimal mode is through micro/mini-hydro power plants to be built on the 19 potential sites along nine principal rivers that drain the five districts comprising the region. It presents the current situation of supply of electricity in the region. This is followed with a detailed study for the implementation of the site at Olewa – the site nearest and with sufficient capacity to supply the current largest load centre in the area, which are the Arua Municipality and its environs. Due to the close similarities amongst those sites, it is argued that the data and findings pertaining to the Olewa one can easily be extended to the others, which thus makes this study beneficial and of direct relevance for the whole region. The paper then proceeds to discuss some of the foreseeable transformations that are likely to emanate from availability of adequate and reliable electricity supply in the region and ends with concluding remarks and recommendations.This Paper presents the results of technical, financial, environmental and management feasibility studies into the provision of reliable, sustainable and environmentally-friendly supply of electricity to the north-west corner of Uganda, called the West Nile Region – a region that is highly populated by comparison with the average population densities of the country and whose location is of both strategic and economic importance in that it serves as a gateway to the Democratic Republic of Congo and the Central African Republic in the west and to the south of Sudan in the north.

    GIS Data Interoperability in Uganda

    Get PDF
    In this paper, we present and discuss data interoperability issues that limit the utilization of GIS Technology in Uganda and other similar developing countries. Using the European interoperability framework principles, organizational, semantic and technical interoperability issues pertaining to Uganda are discussed based on data collected from six major producers of spatial data. Organizational interoperability issues identified include lack of clear and harmonized policies on the exchange of spatial data across institutions and limited collaboration during data and systems development. The major semantic interoperability issues are associated to variations in feature semantics for duplicate datasets where different naming, coding and classification standards are used. Other semantic interoperability issues arise from using ‘equivalent’ spatial data in models that were designed for other environments such as those used for wetland assessment. Technical interoperability issues identified include variations in spatial reference systems and application of different constants to the UTM projection parameters. Documentation of data, development of policies on data sharing, implementation of awareness and capacity building programmes and legislation on SDI are recommended as key steps towards achievement of spatial data interoperability in Uganda

    Remote laboratories represent a significant value to engineering curricula in a variety of cases. Whether it is a complement to a hands-on experience or a substitute when a traditional lab is not feasible, remote laboratories can be a valuable educational resource. Since 1998, the MIT iLab Project has worked to increase the quality and availability of remote laboratories. Using the iLab Shared Architecture, developers of new labs can leverage a set of generic support functions and then share those labs easily and with minimal administrative cost. More recently, the iLab Project, in partnership with Obafemi Awolowo University in Nigeria, Makerere University in Uganda and the University of Dar-es-Salaam in Tanzania and in coordination with the Maricopa Advanced Technology Education Center (MATEC), has focused on building iLabs around the National Instruments Educational Laboratory Virtual Instrumentation Suite (ELVIS) platform. The ELVIS is a low-cost, small-footprint unit that contains most of the common test instruments found in a typical electrical engineering lab. By coupling the ELVIS with iLabs, a variety of remote electronics laboratories can be built and shared around the world. Using this common hardware/software platform, participants in the iLab Project at different levels of the educational spectrum have developed experiments that meet their individual curricular needs and are able to host them for use by other peer institutions. Not only does this increase the variety of ELVISbased iLabs, but it also spurs the creation of teams that can then build other, more diverse iLabs and substantively participate in project-wide collaborative development efforts. Through such coordinated efforts, iLabs can provide rich practical experiences for studentsMaricopa County Community College District.

    This paper presents a low cost GIT based data collection technology that is similar and an input to the ROad Maintenance Data Acquisition System (ROMDAS). It is composed of a vehicle, two digital video cameras, 2 GPS receivers and a notebook computer. Two different camcorders used for comparison purposes (one real color and the other a modified consumer camera to register infrared) are mounted at the front of the vehicle using a homemade gyro mounting. The GPS receivers are placed at the dash board of the vehicle. The notebook computer and GPS receivers are configured to record the position of the vehicle as it moves. The GPS log files maintain recordings of the latitude, longitude, time, speed and altitude of the vehicle position, as the researcher annotates a map document in the ArcGIS 9.3 software with location referencing details and various road attributes. This data collection technology is aimed at exposing the potential of Geographic Information Technologies (GITs) in performing inventory of the road condition. The captured data may be useful for a variety of applications relevant to road inventory and maintenance. It is basically recommended for preliminary road maintenance diagnosis for which in depth road analysis may proceed for the affected road sections. With this technology, it is possible to map road marks and other architecture along the road and provide a map immediately by the end of the survey. In conclusion, data mining of the spatial video databases to facilitate routine and periodic maintenance decisions and the possibility to modify consumer cameras for research purposes is recommended.Denna uppsats presenterar en lÄg kostnad GIT datainsamling teknik som Àr liknande och ett bidrag till vÀgunderhÄll Data Acquisition System (ROMDAS).

    A lot of data is involved in the planning and management of road maintenance operations. Since majority of these operations are based on location, a great deal of this data is spatial in nature. In Uganda, much of this data is stored as text document files, excel data sheets and video logs. Some organisations have nevertheless managed to store these data in Microsoft access databases linked to GIS systems. Even though the structuring of road maintenance data is not uniform, this data is shared by several organisations and often is required as archives for future use. Successful data sharing requires a common schema that is flexible to handle the needs of diverse participants. It is therefore apparent to have a data model that can boost data exchange between these organisations. Basing on document review and analysis of existing road datasets, this paper proposes a data model for road maintenance in Uganda. As foundation to a feasible data model recommendation, the road network numbering & referencing system in Uganda is discussed and a review of the nature of road maintenance data is made. In addition, a review of the fundamental GIS data models in transportation highlighting their major characteristics, strengths and weaknesses is made. Dynamic segmentation as an extension to the traditional arc-node data model is recommended for Uganda. As cited in the paper, several researchers have found this data model successful in dealing with transport planning analysis. Due to the multifaceted and varying aspects of road maintenance data, this model allows for the analysis of precise and high value spatial resolution segments within the GIS. The location of multiple events can be stored with linearly referenced attributes without duplication with route geometry. More importantly, it allows for the sharing of network infrastructure with several applications for which transport data may be required.MĂ„nga uppgifter Ă€r involverad i planering och ledning av verksamheten vĂ€gunderhĂ„ll.

    En översikt över luckor och begrÀnsningar i utnyttjandet av Gits för vÀginfrastruktur UnderhÄll i Uganda

    This paper is part of ongoing research on the use of Geographical Information Technologies (GITs) as decision support tools in road infrastructure maintenance in Uganda. It discusses the gaps in the use of GITs in the road infrastructure maintenance process of Uganda and the limitations experienced while enhancing the use of these technologies. Road maintenance organizations using GITs are often faced with the need and desire to solve similar and cross-cutting technical problems that are repetitive in nature. However, their current institutional arrangements do not permit forging of lasting partnerships, use of standardized data and operating under a coordinated GIS infrastructure. They also lack common and standardized datasets to address key state-wide and local maintenance requirements. Challenges to coordinating how geospatial data are acquired and utilized are the norm in Uganda. Similarly, collection of duplicate data sets at the local and national levels is a common scenario. We finally identify the limitations to use of GITs in the sector as; lack of infrastructure to support utilization of geographic datasets, unavailability of and limited accessibility to geographic data, lack of geospatial capacity at individual and organizational levels and the digital divide. Above all, there are no policies for accessibility and standard use of GITs.Geografisk informationsteknik (Gits), vÀginfrastruktur UnderhÄll (RIM), Data, Uganda Detta dokument Àr en del av pÄgÄende forskning om anvÀndning av Geografisk informationsteknik (Gits) som verktyg för beslutsstöd i vÀginfrastruktur underhÄll i Uganda. Den diskuterar de luckor i anvÀndningen av Gits i vÀginfrastrukturen underhÄllsprocessen Uganda och begrÀnsningar upplevde samtidigt som anvÀndningen av dessa tekniker. VÀgunderhÄll organisationer som anvÀnder Gits Àr ofta konfronteras med behovet och viljan att lösa liknande och övergripande tekniska problem som Àr Äterkommande i naturen. DÀremot medger de nuvarande institutionella arrangemang inte skapa varaktiga partnerskap, anvÀndning av standardiserade uppgifter och arbetar under ett samordnat GIS-infrastruktur. De saknar ocksÄ gemensamma och standardiserade datamÀngder att hantera viktiga för hela staten och lokala underhÄllsbehov. Utmaningar att samordna hur geospatiala data förvÀrvas och utnyttjas Àr normen i Uganda. LikasÄ stÀller samling av dubbla uppgifter pÄ lokal och nationell nivÄ Àr ett vanligt scenario. Vi identifierar slutligen begrÀnsningar för anvÀndningen av Gits inom sektorn, brist pÄ infrastruktur för att stödja anvÀndningen av geografiska datamÀngder, avsaknad av och begrÀnsad tillgÀnglighet till geografiska data, bristande geospatiala kapacitet pÄ individ-och organisationsnivÄ och den digitala klyftan. Framför allt finns det inga riktlinjer för tillgÀnglighet och standard anvÀndning av Gits.Published in the proceedings of the 5th ESRI Eastern Africa User Conference (EAUC
