  • COMPARISON OF DIFFERENT METHODS FOR DETERMINING SATURATED HYDRAULIC CONDUCTIVITY ON ALLUVIAL FLOODPLAIN SOILS IN A SEMI ARID ENVIRONMENT

    Kundiri, A M; Audu, I; Kundiri, A M (2004)
    Soil saturated hydraulic conductivity is an important parameter for flow and transport related processes in the soil but the different methods of its measurement vary under different field conditions. The performance of three in situ  methods were evaluated at 20, 40 and 80 cm depths on an alluvial floodplain soil classified as fine loamy isohyperthermic aeric Trapaquept. TheGuelph permeameter method gave the lowest estimates of saturated hydraulic conductivity, possibly because of small samp...

    Laboratory Evaluation of Free Overfall Equations for Predicting Water Profile over Weir

    Othman, M. K.; Abubakar, S. Z.; Litrico, X.; Belaud, G. (2007)
    Laboratory evaluation of three free overfall equations for predicting water profile over hydraulic structure – weir was conducted in Irrigation laboratory of Higher National College of Agriculture of Montpellier (ENSAM) , France. A broad-crested weir was constructed as a reduced physical model to simulate the gated-structure (Begemann gate) for upstream water control in the Main Canal of Hadejia Valley Irrigation Project (HVIP), Northern Nigeria. Instrumentation in the ENSAM laboratory allows...

    Determination of Sustainable Energy Mix to Meet Nigeria Vision 20:2020 on Power Using Linear Programming

    Mohammed, H. I.; Idriss, I. M.; Baba, D.; Aji, M. M.; Ibrahim, D. (2018)
    Nigeria is rich in energy resources but have serious power problem. This study focused on optimal distribution of power generation among the energy resources. The cost data for plant that will commence operation in 2018 was collected along with power plant efficiency, lifespan, and energy resources reserve or potential. The objective function was the cost of generating 40,000 MW. The model was developed along with constraints on the energy resources reserve. Various constraints were placed on...

    Proportional–Integral–Derivative (PID) Controller Tuning using Particle Swarm Optimization Algorithm

    Bassi, J. S.; Omizegba, E. E.; Mshelia, P. Y. (2012)
    The proportional-integral-derivative (PID) controllers are the most popular controllers used in industry because of their remarkable effectiveness, simplicity of implementation and broad applicability. However, manual tuning of these controllers is time consuming, tedious and generally lead to poor performance. This tuning which is application specific also deteriorates with time as a result of plant parameter changes. This paper presents an artificial intelligence (AI) method of particle swa...

    Laterite Soil Shear Strength Characteristics from the Use of the Standard Proctor and Compression Machine

    Ahmad, K.; Yamusa, Y. B.; Bin Rosly, M. H. (2018)
    This research investigates the influence of compaction methods on the shear strength characteristics of laterite soil. Comparison was made between static and dynamic methods of compaction in order to ascertain their similarity and a better optional method. The use of compression machine is a probabilistic method under uncertainties that is anticipated to produce similar results compared to the Standard Proctor compaction method due to machine wear and tear. Therefore, this research compares t...
