This research aims to design a navigation system for a robot capable of determining its location, navigating towards a target, and studying the proportional differential integral controller. The robot simulates a vehicle with four wheels and a DC motor, controlled by LabVIEW software and a Lidar sensor. Feature locations measured visually, and a module for processing and analysis is developed. The project also outlines localization and SLAM basics, resulting in a concept for implementing...

Parkinson's disease is a common neurodegenerative disorder that affects older people because of environmental or genetic factors. It is defined as a brain disorder that causes unattended or uncontrollable movements such as shaking, stiffness, and difficulties with balance and coordination [3]. There is no cure for disease so far, so the aim of this paper is to produce a stabilizing spoon that will help the patient eat by themselves without the need for help from others, which increases...

  This research addresses the importance of power quality and the problems affecting it, including induction motors that cause an increase in reactive power, resulting in a decrease in the electrical power factor and distortions in voltage and current waveforms, i.e., system instability. It aims to improve the power factor in order to minimize reactive power as much as possible at the generation side by using capacitors connected in parallel with induction motors...

In the ever-evolving of software development, the surge in artificial intelligence (AI) and deep learning technologies has been nothing short of astonishing. As the world bears witness to this transformative era, staying abreast of cutting-edge problem-solving methodologies becomes paramount. To master these techniques, practical experimentation is essential. Among these techniques, the genetic algorithm stands as a venerable tool for addressing complex problems. Its longevity in the field...

The study seeks to investigate the use of technology in education at the Higher Institute of Science and Technology – Souk Al-Khamis, Msayhle, by identifying the main factors that limit faculty members' use of technology in education, the current reality of technology use in education, the importance of technology in education and the educational process, and highlighting the training needs required by faculty members for using technology in education. To achieve the objectives of the study,...

This study utilizes the Taguchi method to optimize control factors for achieving optimal response characteristics, specifically focusing on the threshold voltage (V th ) and leakage current (Ileak) of a PMOS transistor with a gate length of 32 nm. The PMOS transistor design incorporates a high permittivity material (high-k) as the dielectric layer and metal gate materials such as Titanium Dioxide (T iO2 ) and Tungsten Silicide (W SiX ). The optimization of control factors in PMOS...

The research aims to evaluate the impact of fiscal policy instruments on the unemployment rate in the Libyan economy for the period (2008–2021). To achieve this objective, the research addressed the concept of fiscal policy and unemployment, as well as the development of some related economic variables. The descriptive-analytical approach and the statistical and mathematical analytical method were used to measure and evaluate the impact of fiscal policy instruments on the unemployment rate...

Despite having only 54% of the world's vehicle fleet, low- and middle-income countries account for 93% of fatalities. The African continent suffers from a very high mortality rate from road accidents; 26.6 deaths per 100,000 inhabitants, i.e. almost three times more than in Europe. Investigating the case of Libya is very important, hence its statistics show the negative situation of road safety in the country. The aim of this paper is to assess the root causes of road crashes. Using a...

This study aims to explore the role of digital technology, particularly self-learning and virtual reality, in improving the quality of the learning process. The study adopted a structured research methodology and focused on the Faculty of Education at the University of Tripoli as a specific research unit, selecting a sample of students and faculty members. The results of the study showed that students and faculty members prefer using online course platforms as a primary learning tool, while...

In this the study, Blend of poly (vinyl chloride) (PVC) /poly (ethylene oxide) (PEO) was prepared by solution casting technique and the electrical conduction mechanism has been studied at room temperature. The results presented in the form current-voltage characteristics as function of PEO concentrations. Analysis has made in the light of Pool-Frenkel, Fowler-Nordheim and Schottky-Richardson mechanism. It observed that, Pure PVC and PVC/PEO blend samples with PEO <50% has schottky...

This study aimed to search for a solution to linear partial differential equations, which represent many physical and engineering phenomena, and which only appear in the form of mathematical systems that describe the nature of these phenomena. The focus here was on the Laplace equation in the second dimension, as a model for describing these phenomena using the finite difference method. To approximate the solution of these equations, the equation is converted to another form, so that a...

This paper aims to supply electrical energy to oil wells located far from electrical power plants by designing and simulating a standalone photovoltaic (solar) system to feed the electrical loads of the following wells (A46, A60, A58) in the Al-Wafa oil field, which is located in southwestern Libya. This is intended to reduce the cost and effort of connecting these wells to the power grid, as well as to minimize environmental damage to the natural surroundings of the wells. Using the PVsyst...

Modern poultry farming has been transformed by advancements in technology such as Internet of Things (IoT), Information Technology (IT), and Programmable Logic Controllers (PLC). These technologies have revolutionized health management practices by enabling real-time monitoring and control of environmental conditions critical to poultry farming.   This paper explores the design, development, and deployment challenges encountered during the implementation of the Poultry Farm...

Renewable energy is considered an alternative source to reduce the use of conventional energy, as solar energy is among the most popular energy sources, and its radiation can be utilized to generate electricity when it falls on photovoltaic solar panels (PV Panels). In this study, a grid-connected monocrystalline silicon photovoltaic system with a total power of 32 kW, consisting of panels with a power of 400 W each, was designed and simulated. Simulation is necessary to analyze the...

Alzheimer's disease (AD) is a complex neurological illness that has several deep reasons. According to recent research, the use of machine learning techniques (ML) on MRI images can assist in identifying the brain regions and the connections between them that are implicated in dementia. The study aims to review literature from 2017 to 2023 on the use of machine learning algorithms to identify and categorize AD. The precision of each machine learning model is assessed, and mind map models...
