ABSTRACT Soft frequency reuse (SFR) techniques have been deployed to address the problem of interference  experienced  by  users  in  cellular  networks.  In  some  of  these  techniques, resources allocations are based on the assumption that users are uniformly distributed.However, in a real network scenario where SFR is deployed for resource allocation, the distribution of users in the network regions is random. Analysis of the impact of random deployment of users in ...

Abstract Aluminium in Nigeria is a popular metallic element. Widely used to produce single domestic appliances and even industrial engine components. These components display a decrease in performance level after many years of service are discarded and they become waste that tend to be a problem to manage. Furnaces are required for student practice to improve their technical skills, to reduce stress of local blacksmiths and the reduce delays due ...

ABSTRACT Due to urbanization, civic centre has remained a subject of utmost importance because of its role in the city and human existence at large. Civic centre is the city’s symbolic public space where activities such as ceremonial mass gathering, rallies, convention, social and commercial activities takes place. However, civic centres are places that encourage an inflow of people, therefore, there is need to integrate design strategies that will enhance ...

ABSTRACT The Construction industry has been classified as one of the most hazardous industry when it comes to occupational accidents and fatalities. Construction accidents do not only result to demotivation of workers, but also causes delay of project delivery, affect the quality of work delivered, increases overall cost of project, as well as arise to compensation of injured workers among others. The aim of this study was to determine the ...

ABSTRACT Variability has been known as a tool for any crop improvement programme. Yield improvement can be ascertained if there is enough variability existing in a population. Therefore, this study was conducted to asses morpho-agronomic variations in the lowland rice genotypes in an Alpha lattice design with three replications. The experiment was conducted at National Cereals Research Institute Badeggi and Edozhigi in 2017. Parameters such as Days to 50 % ...

ABSTRACT Both Airborne Magnetic and Radiometric dataset were employed to interpret the geology and geological structures that serve as host to gold and other solid minerals within the Bida (Sheet 184) and Zungeru (sheet 163). An area of 55 by 110 km square is contained within the cretaceous sediments of Bida Basin and the meta-sediments of Zungeru- Sarkin-Pawa schist belt. Data interpretation adopted concentrated on mapping geological structures, boundaries and ...

ABSTRACT Gully  erosion is an environmental  hazard that is ravaging the  landscape of Ungogo area. This study was carried out to investigate  the geological and geotechnical  control of gully erosion in the study area. Geological field mapping was carried  out to assess the causes and extent of erosion. Soil samples were collected from four (4) gully sites at depth between 0 - 5m, 0.5 - 1m and 1 - 1.5m ...

ABSTRACT This  research  is  aimed  to  evaluate  stability  of  the  slope  of  newly  constructed  railway embankment  along Lagos-Ibadan  rail line. Soils samples  were collected  from KM75+500, KM90+500,  KM105+500  and KM116+500  at depths ranging from 0m to 5.5m and 5.5m to 10m and taken to laboratory for tests such as particle size analysis, Atterberg limits, standard Proctor  and direct  shear  test. The slope stability  assessment  was done  for the high filled ...

ABSTRACT Global interest on CO2  emission reduction has triggered alternative cement formulation using non-classical raw materials. This work presents a study on optimisation of CO2 uptake by sandcrete-talc composite material. The morphology, mineralogical and oxide composition of the materials were characterized using Scanning Electron Microscopy (SEM), X-ray Diffractormeter (XRD) and X-ray fluorescence (XRF).The result obtained from XRF indicate that sand consist 50.213% SiO2.and 16.001% Si with other diminish amount of ...

ABSTRACT Nowadays varying degrees of road crashes have been recorded from both developed and developing nations of the world. Crashes especially those that involve loss of lives around the world and in particular in developing countries is alarming. The existing solution is in-vehicle accident detection system, which is expensive. In this research work, a less expensive and system that can be widely used to reduce the time to report and ...

ABSTRACT The structure of the Nigerian construction industry is very complex in nature and consists of a wide range of different parties. Despite involvement of all stakeholders on construction projects in the study area projects still encounter challenges in terms of performance due to poor stakeholder management. The aim of this study is to analyze stakeholder management in construction projects in Abuja, with the view to improve construction projects performance. ...

ABSTRACT In construction industry the aim of project control is to ensure the projects finish on time, within budget and achieving other project objective. The advancement of technology in the last century has contributed to the increase in the number of complex construction projects that require proactive cost management. Cost control is an element of financial control since it supplements managerial control process in the organisation. Cost Management of road ...

Abstract Rainfall variability is an important driver of vegetation shift or dynamics. However, the changes are symmetric and have great multiplying effects on the ecosystem and the general livelihood of man. The study examines the vegetation response to rainfall variability in the Sudano Sahelian Ecological Zone of Nigeria (SSEZ). Rainfall data from the Climate Research Unit (CRU) and the United State Geological Survey (USGS) for satellite imageries for the study ...

ABSTRACT Research  trends  in  the  construction  industry  is  toward  the  application  of  nano materials in mortar/concrete which could act as set accelerator due to the ultrafine nature of silica nano_particles (SNPs).
