ABSTRACT: Hemoglobin concentration sensors are created in this study using a row of half-cylindrical rods. The suggested structures are capable of accurately detecting blood sample hemoglobin concentration. Two different topologies based on graphene-plasmonic couples are proposed and explored and a comprehensive review is included in this work. The proposed structures are composed of layers of graphene SiO2, Au, and Ag. Multiple plates and cylindrical-shaped graphene layers are added to the ...
Forensic identification of an individual in this time of unrest in some parts of the world cannot beo .overemphasized. The study was conducted to investigate and determine the body height (Bh)from foot length (Fl). The Bh and Fl of Two hundred and sixty (260) adults(male and female) of participate in Abeokuta Southwest Nigeriaa, ages ranged between 24 years and 55 years
A beautiful process of work which is capable of turning the normal moment into a lifelong memory
A modeling with a good predictive rate is necessary to create a good performance of the predictive controller . The correct and better model to use is the Predictive Control Model (MPC) or the Predicted Control Model. This study determines the control optimization system with the Predicted Control Model for the plant of Multi Input Single Output (MISO). The MPC optimal control system designed for the closed-loop Mismatch method, the effect of changes in the Kalman amplifier state estima...
The life of a transformer is associated with the state of the insulation system, one of the techniques used to measure the insulation system is frequency-domain spectroscopy (FDS), which measures the dielectric properties in the frequency domain. This work establishes a mathematical model with the data of the FDS to estimate the parameters of the equivalent circuit of the dielectric response of the paper-oil isolation system of the transformer, which is a group of non-linear eq...
Abstract The paper seeks to provide technological solutions to the security issues bedeviling Nigeria and its environs using technical tools and partnerships with the right international institutions to handle public safety issues. Some of the areas where the paper seeks to profer solutions are partnership, use of telecommunication services, having a unified database for every citizen and people living in Nigeria, and provision of facial recognition devices to combat these crimes. Keyword...
This research was designed to comparatively analyze practical skills acquisition in the Electrical/Electronic Engineering department in Accra and Kumasi Polytechnics. The study population was made of 578 students in the Department of Electrical/Electronic Engineering from the two study institutions respectively. A sample size of 25% was randomly selected from the total population. A total number of 145 questionnaires were distributed and 123 completed questionnaires were received making a res...
Using Computational Fluid Dynamics (CFD), this paper investigates the effect of mesh material properties on the heat convection and conduction (fluid-solid interaction) of a vertical impinging round jet onto a stationary and moving horizontal surface, as well as the effect of conjugation in the solid domain. This paper is an excerpt from an assignment in Numerical Thermoflow that was completed in 2021 during my Bachelor of Science Honours in Applied Science Mechanics at the University of Pret...
The purpose of this paper is to perform path tracking for a non-holonomic mobile robot subject to kinematic disturbances using model prediction and H-2/H-infinitycontrol and by Gain-scheduled control law. In this method, the problem of tracking a mobile robot is expressed in such a someway that its kinematic error is in the form of linear parameter variable with bounded disturbance, the purpose of the design is to stabilize the controller by solving the LMI conditions for the error tracking...
Drones are not inherently stable, necessitating the use of a flight controller. If the UAV is properly tuned, the drone will fly steadily; otherwise, it won't. Hence, we have used a PID (proportional, integral, differential) controller for a stable flight. A well-functioning PID controller should enable amazing climbs and long-range flights. But, when used singly, PID controllers can provide poor performance, resulting in a long settling time, overshoot, and oscillation. Here, we propose a ne...
Abstract Pond ash is an unwanted product from thermal power stations. Way of reducing the pollution of pond ash disposal determinations is recycled and reused in different engineering applications. The quality of pond ash can affect the quality and strength of engineering applications. This research paper using fiber reinforcement techniques to improve the geotechnical properties of pond ash. Polypropylene fiber is used to reinforce for stabilization of pond ash. In this research, some labora...
Abstract The utilization of solar incubator would proffers solution to a major constraint of power inadequacy for commercial poultry egg incubation in Nigeria. A solar powered poultry egg incubator was developed and the main components included incubating chamber, control system and solar powered system. The developed solar incubator was 610 mm × 607 mm × 1649 mm in size with a capacity for 150 eggs. This study conducted performance evaluation on the solar powered poultry egg incuba...
Out-of-hospital cardiac arrest (OHCA) is a cessation of cardiac mechanical activity that occurs outside of the hospital setting and is confirmed by the absence of signs of circulation. OHCA affects nearly 1000 adult Americans every day, with overall survival rate of 10.4%. Based on previous work in this subject I try to calculate the joint probability distributions of the neurological outcomes of the OHCA outcomes in our records, based on the Event Demographics, Field Care, and Hospital Care....
Abstract Outlier is a questionable plot value which differs greatly from the mean of all other replications of a specific treatment while trial error may occur as a result of a mistake in measurement or transcription during data collection or entry. The presence of any of the two confounds the inferences made from the data analyses especially the F-statistic whose estimate is based on sample means and variances. This report was intended to show how Genstat statistical software package assists...
Abstract Selected physical properties of Afzelia africanaseeds were determined at four moisture levels: 10.60%, 12.80%, 15.20% and 18.40% wet basis (w.b). The seeds were categorized in three batches according to their weights: Batch I (2g Batch III (3.99spectively. Arithmetic and geometric mean diameters, sphericity and projected area ranged from 13.5700.43-15.8230.41mm, 12.2450.33-14.4300.39mm, 57.800.07-75.600.03% and 186.21828.42-256.03712.98mmrespectively.
