Query execution for rdf data using structure indexed vertical partitioning (2015)
Presentation / Conference Contribution

The paper explores use of various partitioning methods to store RDF data effectively, to meet the needs of extensively growing highly interactive semantic web applications. It proposes a combinational approach of structure index partitioning and vert... Read More about Query execution for rdf data using structure indexed vertical partitioning.

Data management for Internet of Things (2015)
Presentation / Conference Contribution

Internet of Things is projected to connect uniquely identifiable devices over the network to build an interactive system with high velocity and volume of data placing forth a challenge of interoperability between such devices. RDF provides a common s... Read More about Data management for Internet of Things.

Secure and privacy-aware traffic information as a service in VANET-based clouds (2015)
Journal Article

The multitude of applications and services in Vehicular Ad hoc NETwork (VANET) and cloud computing technology that are dreamed of in the near future, are visible today. VANET applications are set to explode in the next couple of years as a result of... Read More about Secure and privacy-aware traffic information as a service in VANET-based clouds.

Energy optimization in commercial FPGAs with voltage, frequency and logic scaling (2015)
Journal Article

This paper investigates the energy reductions possible in commercially available FPGAs configured to support voltage, frequency and logic scalability combined with power gating. Voltage and frequency scaling is based on in-situ detectors that allow t... Read More about Energy optimization in commercial FPGAs with voltage, frequency and logic scaling.

Growth, change and decay: Plants and interaction possibilities (2015)
Presentation / Conference Contribution

Our work explores using plants as an interaction material to extend and disrupt existing notions of HCI. We focus in particular on how the affordances and properties of plants can be utilised for enhanced physical and emotional interaction between pe...

Data partitioning for semantic web (2014)
Journal Article

Semantic web database is an RDF database. Tremendous increase can be seen in semantic web data, as real life applications of semantic web are using this data. Efficient management of this data at a larger scale, and efficient query performance are th... Read More about Data partitioning for semantic web.

Enterprise resource planning (ERP) systems - Is Botswana winning? A question on culture effects (2014)
Journal Article

As the economy of the country is improving, organisations across Botswana are increasing their investments in Enterprise Resource Planning (ERP) technology as a way of helping in the growth of their business. Some institutions that have implemented E... Read More about Enterprise resource planning (ERP) systems - Is Botswana winning? A question on culture effects.

On the prime graph of simple groups (2014)
Journal Article

Let G be a finite group, let π(G) be the set of prime divisors of jGj and let Γ(G) be the prime graph of G. This graph has vertex set π(G), and two vertices r and s are adjacent if and only if G contains an element of order rs. Many properties of the... Read More about On the prime graph of simple groups.
