ABSTRACT The construction industry of any nation is one of the greatest and most important sectors that strengthen economic development. It is the least sustainable industry in the world as it consumes more than half of all the non-renewable resources humankind use in construction works, especially housing. The activities of the industry contribute greatly to environmental pollution which is among the world largest consumer of energy, material resources, water, and ...

ABSTRACT Soil water characteristics are critical hydraulic properties governing soil water availability and movement in soils. Sustainable soil water conservation would not be possible without accurate knowledge of these hydraulic properties. Study of soil properties such as field capacity (FC), permanent wilting point (PWP) and hydraulic conductivity (Ks) play important roles in soil moisture retention.  These parameters can be measured directly; their measurement is difficult and expensive. Thus, Saxton and ...

Abstract High-rise is generally a building that is greater than (22.5 m), and with 7 to 10 stories. They could also mean structures with improved construction activities and enriched with technology that will help in reducing land scarcity, urban density and can accommodate large families in a lesser space. Condominium on the other hand, is a building divided into several apartments or units, and each unit is occupied or managed ...

ABSTRACT Polymer concretes (PCs) are known to be less permeable to water, but its usage is less popular in tropical countries like Nigeria because its common binder, thermoset resins, are very sensitive to rising temperature. This sensitivity to temperature accelerates the polymerization process and this jeopardizes its early strength development, thereby producing a PC with low workability and high porosity. To address  this, polymer inhibitors with addition of Methyl Methacrylate ...

ABSTACT It is common knowledge that the end user of stream flow data may necessarily not have any prior knowledge of the quality control measures applied in their generation. Thus, this study provides an intuitive attempt to provide an independent quality indicator to boost the confidence in the use of stream flow data by developing regional flow duration curves for selected ungauged station of the upper Niger River Basin, Nigeria. ...

Device-to-Device Communication comes with numerous benefits which include data traffic offloading, location awareness service, social networking  and  smart  city.  However,  this  D2D  Communication  Network  comes  with several challenges such as Interference Management which causes great impairment to communication.  Therefore, ...

ABSTRACT There is a standard of 99.999% (five ‗nines‘) availability for telecommunication hardware and software. This is to guarantee the high level of service required by the Mobile Network Operator  (MNO) for service delivery. MNOs in Nigeria and most sub-Saharan Africa countries are, however, not being able to meet up with the expected base station availability mainly due to high restoration time after the outage. In this thesis, the historical ...

ABSTRACT Wireless sensor networks (WSN) consist of micro-sensors capable of monitoring physical and environmental factors. These are often mainly made up of resource constrained sensor nodes and gateways. Networking these nodes presents several challenges because the devices have limited computational capability, data storage, energy and communication bandwidth.
