The focusing position and pump beam spot sizes are critical factors in determining the performance of the end-pumped Nd:YAG laser. Understanding and optimizing these parameters can help researchers and engineers enhance the laser’s efficiency, leading to improved applications in various fields. To investigate this, we conducted a series of experiments by varying the focusing position…
Economic dispatch (ED) is one of the main problems addressed in the study of power supplying load demand. There are many proposals for this optimal fuel cost in power generators. In this paper, ‘Ant Lion Optimization Algorithm’ (ALO) is used for solving this ED problem. ALO Algorithm is one of the new Meta-Heuristic methods. Ant…
This paper proposes using Linear Matrix Inequality (LMI) for robust controller design in a three-phase grid-connected inverter (GCI). The controller, applied to a three-phase dc-ac inverter, integrates state feedback and error correction within the dq-rotational frame to eliminate offset errors. An LMI-based optimization minimizes settling time despite uncertainties in the L-filter (expressed as resistance and…
In this project, the Proportional Integral (PI), Integral Proportional (IP), and Proportional Integral Derivative (PID) algorithms are used for controlling the speed of the DC motor. These controllers were developed using MATLAB/SIMULINK for better outcomes. Controllers are made for closed-loop systems. PID tuning is used in this instance to design P-I, I-P, and PID…
Economic load dispatch (ELD) is the process of generating real and reactive power from the generator to meet the power demand of the power system while minimizing fuel costs as the generator input. To solve the ELD problem with maintaining voltage stability, the Improved Particle Swarm Optimization (IPSO) method was proposed in this paper. The…
In the standalone operation mode of the microgrid, the system is significantly weakened due to a lack of inertia support from the conventional synchronous generator. Hence, in-vestigation of the impact of photovoltaic (PV) power variation and load transition on the standalone microgrid system both stability and quality are essential. In this paper, a mi-crogrid system…
S45C carbon steel is a common engineering steel and widely used for many industrial applications such as machine structures, gears, shafts, axles, bolts, etc. The purpose of this research is to investigate the cutting parameters (feed rate and spindle speed) in different levels to evaluate the surface roughness (Ra) of S45C steel in the dry…
In this study, two-way reinforced concrete (RC) slabs were studied and evaluated using different methods including Moment Coefficient Method (CM), Direct Design Method (DDM) and Equivalent Frame Method (EFM). Moreover, the design of RC slabs was also conducted by computer program, ETABS 2021. The slab chosen to study was the 6m x 6m two-way slab…
To find ways of reducing the risks of lateral torsional buckling on the perforated sections in web by adding transverse stiffeners is the purpose of this study. The comparison of the T-shaped transverse stiffeners and normal transverse stiffeners was found that the use of T-shaped transverse stiffeners with the thickness increasing, reduce the lateral displacement…
Fiber Reinforced Polymers (FRP) has known as the most essential materials for structure strengthening. Most of old and new structures were selected FRP for strengthening in Cambodia and other countries. The aim of this study is to explore more detail about the methods and techniques involved in strengthening structure by using FRP. FRP is really…
