The study aimed at demonstrating the positive outcome of incorporating optimization techniques in the design procedure for designing steel-concrete composite bridges was conducted. Optimization algorithms have the capability of finding optimal or near optimal solutions in complex problems. In...

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...

Mining at Kansanshi is currently conducted in two pits namely Main and North West pit. Mining at both pits is conducted by conventional open pit methods involving 18 hydraulic excavators and a mining fleet of haul 86 trucks.There has a been a general concern on the mined material tonnes...

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...
