In practice, cured concrete strength may exhibit strength variation from batch to batch and within batch despite the mixes being of the same proportions and with quality control. On the other hand, structural concrete elements are designed to meet specific characteristic strength. In order to...

Despite playing a key role in most economies, building construction contributes significantly to climate change. Buildings consume energy, water, and raw materials, generate waste, and emit potentially hazardous air emissions during the course of their lives. These facts have prompted the...

In any company, the planning and scheduling process is unavoidable. This research investigated its effects in the electrical section of Anvil Mining Congo SA. In this company, the focus of planning and scheduling, particularly on equipment, is on preventative maintenance rather than actions such...

Natural-convection solar tunnel dryers capable of achieving greater drying rates when drying products. The increased temperature decreases the relative humidity of the air, thereby allowing the air to more efficiently dry the product. However, it is necessary to provide an appropriate solar air...

The design and development of ytterbium-doped fibre lasers (YDFLs) operating around 1018nm laser wavelength and pumped around 976nm has advanced in technology since the first ytterbium laser was tested in 1988. The fiber lasers are used in various sectors such as communications, material...

A number of research concerns have arisen in the concrete research community on the fire resistance of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) beams, despite their improved mechanical properties at ambient temperature. The traditional experimental approach to performance-based...

This dissertation investigates the effect of spectral efficiency as the number of service antennas and number of users in Multiple-input Multiple-output (MIMO) Long Term Evolution (LTE) network increases. The channel estimators studied namely Zero Forcing (ZF), Minimum Mean Square Error (MMSE)...

Concrete is one of the most widely used construction material in the world and the construction industry is looking for ways of making concrete using greener methods so as to reduce ecological effects on the environment that come as a result of large scale exploitation of natural aggregates. The...

In Zambia part of the electric grid is not monitored, this means that there are no sensors in the electric grid to enable grid status information to be sent to the power utility. Without these sensors the power utility finds it difficult to determine when there is a power failure in the...

In Zambia it is estimated that the existing housing stock stands at 2.5 million units catering for about 16 million people. The national housing deficit stands at more than 2 million houses and is compounded by urbanisation. Efforts have so far been made to use alternative building technology...
