The research is concerned with the presentation of a tutorial extract on the Graeffe’s Root-finding scheme derivation and application for the solution of third degree Polynomial of the form, f(x) = 0. Thereafter, we tested the efficiency of our proposed scheme by applying it to a range of Third Degree polynomial problems in literature reviewed. The outcome of the comparison of the roots generated by the Graeffe’s root-finding scheme to their respective exact solution showed that the scheme gave a better approximation to the exact solution at every fourth iteration. Thus, the proposed scheme in this research can be said to be another better suitable numerical approach for the solution of third degree polynomial that their exact solutions are difficult to arrive at. The procedures for the scheme derivation can be easily followed for the solution of other higher degree auxiliary equations.

In every nonabelian neutrosophic p-group G(I), possessing two neutrosophic cyclic subgroups X(I)i and X(I)j , the quotient neutrosophic group of G(I) by X(I)i is isomorphic to the neutrosophic cyclic group X(I)j for i, j ∈ {1, 2}, i /= j. Moreover, if p > 2 and G(I) is metacyclic, possessing a neutrosophic nonabelian section Y (I), of order p³, then Y (I) is a trivial neutrosophic subgroup of G(I).

Artificial intelligence or AI is the simulation of human intelligence by software coded heuristics.

Artificial intelligence has the power to aggregate and harness the potential of thousands of human minds put together.

Novel Prototyping Development Board (Source-Era) for an Encompassing Software/Hardware Production

Tue, 19 Mar 2024 00:00:00 +0000

In programming and reprogramming of a controller, a setup known as Prototyping platform is required, and three things are involved: Software IDE to write the code, hardware development board to transfer the code and the prototype components to assemble and test the work. Prototyping platforms give software/hardware developers a platform to ease the design and implementation of complete electronic solutions that lead to quality products. To encourage an increase in numbers of developers and thus products, such platforms must meet the requirements of ease of use, expandability and cost which most existing platforms lack. The need for cost effective development board that is robust, expandable and ease of use informed this work. The introduction of Novel Prototyping Development Board (Source-Era), is a big boost to software/hardware production. The board explores microcontrollers such as PIC18F873, PIC16F876, dsPIC, ATMEGA328A and more without changing the development board or performing any soldering activities. It also has the ability of interfacing a controller with different input and output device based on their signal type which include Universal Asynchronous Receive and Transmit (UART) Protocol, Serial Peripheral Interfacing (SPI) Protocol, Inter Integrated Chip (IIC or I2C) protocol, Analog signal processing protocol (ASP), Boolean Digital, Pulse width Modulation (PWM).

Solar photovoltaic system design is mainly predetermined by the system requirement, environmental governing policies, standard and awareness. These and others, are measured ingredients considered in this sustainable design of the stand-alone solar household project in Wukari. In this project, the PV design is mainly influence by the number and types of appliances used. A system capable of supplying energy for a typical house in Wukari was design and components sizing were approved. The key structure’s gears such as the photovoltaic panels, battery, charge controller and inverter are stated, taking the insulation level of ten (10) average hours of sunlight per day with an estimate for a total cost of the system. The total electrical supply to the load appliances of 5190W in the building will be from the PV source. To power these appliances, 4 modules with the power rating of 220W under a standard test condition (STC)of 1000W/㎡ and 25°C temperature, 4 batteries of (24V-200Ah) in the battery bank with system battery capacity of 848Ah, one charge controller of 50A-24V is selected and a 2KVA inverter is required. The aim of this work is to size each component of a PV system based on the numbers, types, and wattage of the appliances and design a suitable Off-grid/Stand-alone PV system that can generate reliable 24 hours power supply within the residential household eliminate grid dependency.
