Zambian Secondary Schools have experienced a low performance in Mathematics at School Certificate level. Analyses of the results in terms of questions and facts on the examination indicate that Transformation Geometry is one of the topics in Mathematics in which pupils are not performing well....

In this dissertation, we examine the small and large sample properties of the U-statistics (Un) for an estimable parameter : For small sample, Un is found to be MVUE and Su cient. Large sample properties of Un examined are Consistency and Asymptotic normality. We also compare the rate of...

In the determination of an improved geoid over Zambia, the Modified Stokes’ formula employing the RCR technique was used. The formula combined EGM2008 data, terrestrial classical free-air gravity anomalies over Zambia, and the SRTM 3′′ DEM over Zambia which represent the long, intermediate, and...

A collection of computers linked together through a communication channel are known as a computer network. Such a network facilitates communication and resource sharing between netwo rks. The linkages are facilitated by data transmission lines, which can be optical or Ethernet cables . The data...

The economic growth and industrial development of any county requires a drive from energy hence the industrial development of any nation is dependent on its energy supply. Demand for energy in Zambia has been rising due to robust GDP growth of more than 6 percent per year for the past decade in...

Konkola Mine is one of the wettest mines in the world. It pumps about 350,000m3 of water per day. From the inception of mining operations in 1956, water has always posed a challenge to mining despite the use of dewatering strategy involving dewatering crosscuts and dewatering boreholes. The...

Soil plaster pastes have been used around the world by local rural populations for centuries to give a finishing touch to their houses, and depending on the soil used, some chemical contamination cannot be ruled out. Some soils may contain heavy metals and other parameters depending on where it...
