This research work, which presents a simplified technique of modelling steel fibers, uses python algorithm that can be directly run in ABAQUS to automatically generate the location and orientation of steel fibers in a rectangular ultra-high performance concrete specimen, so that the effect of steel fibers on the properties of such a specimen can be directly investigated through numerical simulation. This method is fast, can be applied to structural members of bigger dimensions (like beams,...
In addition to the inherent advantages of an outrigger system over conventional framed structural system, damped-outrigger systems (DOS) enhance it further with its agility to resist lateral loads in high-rise buildings. Dynamic response of slender and flexible buildings with DOS induces vibration control in which twisting of core structure is restricted by shear deformation of the damper present at the end of outrigger connected by perimeter columns. In this paper, a 300 m tall core-tube typ...

Abstract: Nuclear radiation protection is crucial for future development in the field of Nuclear energy generation. This work categorizes the various types of radiation protection. It is a comprehensive review of nuclear radiation protection.
ABSTRACT: The inconsistency present in Transmission line tends to have a cascading collapse and different types of failures in the transmission line of a power system which impact the power transfer capability of the line. In this paper we used MATLAB coding to plot the real power and reactive power with voltage. We want to predict what happens to the stability of a power system before a cascading collapse. Note: The MATLAB code was intentionally added to this work to serve as a base for...
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...
