  • Causality of Unemployment and Macroeconomics

    In order to test the wellbeing and development of a given nation economy, unemployment level is a primary macroeconomic pointer. It is considered as forgone output which denies the fundamental assets of government that required creating the economy. Thus, the objective of the study was to investigate the long-run and short-run causality between unemployment and macroeconomic variables. Resulting to utilizing the Augmented Dickey-Fuller to test for unit root this investigation utilized Auto Regressive Distributed Lag limits testing approach and Vector Error Correction Model granger causality test to inspect the time arrangement information over the time of 1984/85-2018/19. Relapse result recommends that since quite a while ago run causation running from joblessness to the recorded macroeconomic factors. In the short run there is significant granger causality from foreign direct investment and inflation rate to unemployment rate. Moreover, from unemployment to real gross domestic product and external debt in the short run. Finally, the study suggests the government should increase the level of aggregate supply, create conducive environment that entice more foreign direct investment and borrow only for productive purpose to form more business and assimilate an expensive pool of unemployment populace.


    The study investigated the impact of federal government expenditure on the Nigerian economic development. The main objective of the study was to ascertain whether there is a relationship between federal government expenditure and economic development in Nigeria. The study adopted Least Square estimation technique to evaluate the model specified using time series from 2010-2018. Real Gross Domestic Product was used as the dependent variable while federal government capital and recurrent expenditures were used as the independent variables. The result from the regression analysis shows that federal government capital and recurrent expenditures have a positive effect on real GDP. The data used in the analysis were gotten from Central Bank of Nigeria (CBN) statistical bulletin. The study recommended that federal government should direct more of its recurrent expenditure towards economic and community services as they accelerate economic development. The study also recommended proper management of public funds allocated to the agricultural sector and manufacturing industries as they have the potential of raising the nation’s production capacity and providing employment for citizens in the country.

  • Investigation of forced convective heat transfer in nanofluids

    The present paper concerns a theoretical study of heat transfer of the laminar two dimensional flows of various nanofluids taking into account the dissipation due to viscous term past a 2-D flat plate had a different temperatures. The steady incompressible flow equations were used and transformed to a nonlinear Ordinary Differential Equation (ODE). These equations were solved numerically using implicit finite difference method. Three types of nanoparticles in the base flow of water were considered. The symbolic software Mathematica was used in the present study. Different types of nanoparticles, different values of, nanoparticle volume fraction, Eckart and Prandtl number were tested and analyzed at different wall temperature. The effect of these parameters on the flow behaviour, the local skin friction coefficient, Nusselt number, the velocity and the temperature profiles were presented and investigated. It is concluded that these parameters affect the fluid flow behaviour and heat transfer parameters especially nanoparticle concentration. The presence of nanoparticles showed an enhancement in the heat transfer rate moreover its type has a significant effect on heat transfer enhancement.


    Electroencephalogram or EEG is a trace of Brain action from different locales of the cerebrum. It is the electrical movement and activity determined by putting the electrode terminals on the scalp. Artifacts are unnecessary noise signals in an EEG record. These noise in recording EEG sham a major mortification for EEG interpretation and disposal. Categorization of artifacts depends on source of its creation similar to Physiological artifacts along with Exterior artifacts. Recognition of artifacts, identification of artifacts as well as eradication of artifacts is a significant procedure to diminish the possibility of false impression of EEG not only for clinical but also for non-clinical fields. The majority of recording convention. There are various strategies for artifact removal which incorporates manual and automatic techniques. Morphology and Electrical distinctiveness of artifacts can show the way to fake elucidation that is intolerable in support of clinical as well as non clinical utilization. Thus artifacts in EEG signals must be removed or minimized before further interpretation. The presented paper describes a review on detection, classification and removal/ minimization of the recorded EEG signal artifacts.
