The present day cellular network faces an increasing problem of providing capacity and coverage for users. The Long Term Evolution (LTE) system provides a number of ways in vi mitigating these problems among one of which is the deployment of femtocell technology. The femtocell is an example of a heterogeneous network which comprises of different la... Continue Reading
This research work presents the development of a position and trajectory tracking control of ball and plate system. The ball and plate control system was considered as a double feedback loop structure (a loop within a loop), for effective control of the system. The inner loop was designed using linear algebraic method by solving a set of Diophantin... Continue Reading
This research work presents the development of an improved ergodic capacity of underlay Cognitive Radio (CR) with imperfect Channel State Information(CSI). An underlay CR network under a Peak Interference Power (PIP) constraint imposed by a Primary User (PU) was considered .A closed former godic capacity expression of the Secondary User (SU)under P...

This research presents thedevelopment of an improved Intrusion Detection based Secured RObust Header Compression (IDSROHC)techniquefor handling brute force attack. The secured RObust Header Compression (secured ROHC) was developed to secure Internet Protocol version six (IPv6) packets against false initial refresh attack by encrypting the cyclic re...

This study was carried out to examine the effects of Single Super Phosphate with Wood ash on the production of biogas from Cow Dung and Chicken Droppings mixed with Digitaria Smuts II. An existing digester design was adopted (3 in 1 floating drums) and fabricated using locally available materials to digest Cow Dung from Kawo Abattoir, Chicken Dropp... Continue Reading
Optimal siting and sizing of Distribution Flexible AC Transmission Systems (D-FACTS) devices in power distribution networks maximizes loadability, compensates reactive power, minimizes power loss and enhances voltage profile. The search for optimal size and locations of these devices in radial distribution networks is challenging and requires robus... Continue Reading
The water supply infrastructure in Kaduna North Water Works (KNWW) has faced alot of problems, partly due to a neglect of the components over a long period and with tariffs at a low level, which was far from reflecting the real cost of the service. Economic efficiency still remains below the regional average, resulting in the lack of financial reso... Continue Reading
In this thesis, a diagnostic assessment of the entire water supply distribution network was carried out in order to evaluate problems associated with water supply in Minna. This assessment was carried out by conducting inventory of all the facilities in the entire water supply distribution network by onsite, physical and visual inspection of all th... Continue Reading
This research presents the design and configuration of Multi-Protocol Label Switching (MPLS) technology to address scalability issues on a large and complex campus network such as Ahmadu Bello University campus network that is currently designed, configured and implemented with Open Shortest Path First Protocol (OSPF) network. Graphical Network Sim... Continue Reading
Enhancement of the friction-reducing properties of degraded 20W-50 engine oil by blending with neem and palm kernel oils respectively for application in cold upset-forging of aluminium alloys has been investigated using the ring compression test procedure. Three sets of blends of each of the vegetable oils with the degraded engine oil in the ratios... Continue Reading
In this research work, the optimal conditions for glucose and bio-ethanol production from Spirogyra africana were studied. The Spirogyra africana samples collected from the Ahmadu Bello University Zaria Dam were dried, milled and sieved to ? 125 ?m, and subsequently analyzed for carbohydrate content. Prior to hydrolysis, a set of the samples was pr... Continue Reading
The Swift simulative formability test was employed. in this research work for the assessment of some locally produced vegetable oils viz: Palm oil, Palm Kernel oil, Cottonseed oil and Groundnut oil as lubricants in deep drawing operations. The assessment of these local oils was based on Swift test parameters; the limiting drawing ratio and the maxi... Continue Reading
This study had investigated the admixture properties of plantain peel ash through a series of laboratory experiments. This was targeted at obtaining an effective admixture while relieving the environment from the menace of environmental pollution arising from indiscriminate disposal of agricultural wastes. Plantain peel ash was blended with dry cem... Continue Reading
This study, investigated the creep behaviour of Black Afara (Terminalia ivorensis) timber in accordance with EN 408 (2004) and EN 13153 (2002). The data were analysed based on the Eurocode 5 (2004), Eurocode 0 (2002), JCSS (2006) and EN 384 (2004) specifications using Easyfit statistical package. The statistics of the reference material properties ... Continue Reading
The effect of hot-sesame oil bath as an austempering medium for ductile cast iron was investigated. Samples of ductile cast iron were machined to standard dimensions for tensile, impact and hardness/microstructural analysis test specimens prior to the austempering process. Sesame oil was used as hot quenching bath for the austempering process. The ... Continue Reading
