Application of a Class of Preconditioners to Large Scale Linear Programming Problems
(Springer, 1999)In most interior point methods for linear programming, a sequence of weighted linear least squares problems are solved, where the only changes from one iteration to the next are the weights and the right hand side. The ... -
Properties of Preconditioners for Robust Linear Regression
(Fountain Publishers, 2000)In this paper, we consider solving the robust linear regression problem y = Ax + ∈ by an inexact Newton method and an iteratively reweighted least squares method. We show that each of these methods can be combined with ... -
The Impact of Equal Weighting of Low and High-Confidence Observations on Robust Linear Regression Computations
(BIT Numerical Mathematics, 2001)Equal weighting of low- and high-confidence observations occurs for Huber, Talwar, and Barya weighting functions when Newton’s method is used to solve robust linear regression problems. This leads to easy updates and/or ... -
On the Convergence of an Inexact Primal-Dual Interior Point Method for Linear Programming
(Springer, 2005)The inexact primal-dual interior point method which is discussed in this paper chooses a new iterate along an approximation to the Newton direction. The method is the Kojima, Megiddo, andMizuno globally convergent ... -
On Efficient Distribution of Data in Multicast Networks: QoS in Scalable Networks
(Springer, 2005)Multimedia applications or real-time applications such as audio and video on demand, teleconferencing and whiteboard sharing require Quality of Service (QoS) guarantee assurance. QoS constraints, namely required bandwidth, ... -
Measuring Computing Research Excellence and Vitality
(Fountain Publishers, 2006)Measuring computing excellence and vitality has become an important approach to understanding sustainable information and communication technology (ICT) for societal transformation and development around the world. In ... -
A Methodology for Feature Selection in Named Entity Recognition
(Fountain Publishers, 2007)In this paper a methodology for feature selection in named entity recognition is proposed. Unlike traditional named entity recognition approaches which mainly consider accuracy improvement as the sole objective, the ... -
ICT as an Engine for Uganda’s Economic Growth: The Role of and Opportunities for Makerere University
(Fountain Publishers Kampala, 2007)The use of Information and Communications Technologies (ICT) to improve how goods are produced and services are delivered is a feature of everyday life in developed countries. If ICT is used appropriately, it has the ... -
The Role of Academia in Fostering Private Sector Competitiveness in ICT Development
(International Journal of Computing and ICT Research, 2007)Increased adoption of eCommerce and Information and Communications Technology (ICT) in the private sector often leads to expanded economic growth by opening new markets, increasing access to market information, and improving ... -
Geometrical Spatial Data Integration in Geo-Information Management
(Fountain Publishers, 2007)One of the reasons that Individual users and organizations use GIS, is to exchange geospatial data as a means to location based decision-making. A considerable amount of preprocessing has to be done, before and after the ... -
Generalized Association Rule Mining Using Genetic Algorithms
(Fountain Publishers, 2008)We formulate a general Association rule mining model for extracting useful information from very large databases. An interactive Association rule mining system is designed using a combination of genetic algorithms and a ... -
ICT-enabled Services: A Critical Analysis of the Opportunities and Challenges in Uganda
(Fountain Publishers, 2008)Information and Communications Technologies (ICTs), broadly defined, facilitate by electronic means the creation, storage, management and dissemination of information. ICT is both a vehicle for communication and a means ... -
A Generic E-Learning Framework: A Case Study Faculty of Computing and Information Technology (CIT) Makerere University
(Fountain Publishers, 2008)Advancement in Information Technology (IT) has led to better facilities and services for learning within educational organizations. Many higher educational institutions of learning have adopted technology in their learning ... -
Exploring the Implementation of Blended Learning in a Developing Country: A Case Study of Uganda
(Fountain Publishers, 2008)This paper explores on how the blended learning method has been implemented in the developing country such as Uganda. Many higher education institutions in Uganda have acquired a new form of learning using technology ... -
Information Communication Technologies Acceptance and Use Among University Communities in Uganda: A Model for Hybrid Library Services End-Users
(Fountain Publishers, 2008)Since their inception during the first century, library institutions have used manual operations to provide services to patrons. Information seekers in these libraries spent a lot of time perusing through card catalogues ... -
Web Content Filtration according to context of use: Case Study of Accessibility Guidelines
(Fountain Publishers, 2009)In this paper, we propose an approach for filtering Web based content according to context of use based on user roles and other use case scenarios. The purpose of the filtration approach is to make such Web content easier ... -
Improving reliability and functional sustainability of groundwater handpumps by coating the rubber piston seals with diamond-like carbon
(Honor, 2015)In many rural communities, handpumps are essential in order to provide access to safe drinking water from groundwater sources. The functional sustainability of handpumps is poor, however, and most maintenance issues in ... -
A Review of Termination Rules of an Inexact Primal-Dual Interior Point Method for Linear Programming Problems
(Investigación Operacional, 2018)In this paper we apply the Inexact Newton theory on the perturbed KKT-conditions that are derived from the Karush-Kuhn-Tucker optimality conditions for the standard linear optimization problem. We discuss different ... -
A Comprehensive Review on 2D and 3D Models of Vertical Ground Heat Exchangers
(Renewable and sustainable energy reviews, 2018)The ground source heat pumps (GSHPs) have been extensively applied to commercial and residential buildings owing to their high-energy efficiencies and low running costs. The key component of the GSHP is a ground heat ... -
Cloud RAN and MEC: A Perfect Pairing
(ETSI MEC, 2018)CRAN and MEC are highly complementary technologies. Collocating these helps make the economics of each of them significantly more attractive. Collocating CRAN and MEC also helps an MNO to support (and generate revenue ...
