Fan Mobility by Generated Electricity Harnessed from Dynamo

Orvin A. Lobitos — 2024-04-10

Fans are the most popular products despite the broad accessibility to air conditioners and coolers. There's a chance that using air conditioners more frequently to cool indoor areas will be a major contributor to greenhouse gas emissions worldwide. Using home fans to move indoor air can increase the temperature at which air conditionin g must be turned on to keep building occupants comfortable (Malik et al, 2022). Household fans are a great way of helping improve your home feel better because they reduce interior temperature, manage humidity, and offer energy-saving advantages. Programmers begin by using the Dynamo to create robotic outputs and other electronic and programming creations. Dynamo produces direct current electric power using electromagnetism. It is also known as a generator; however, the term generator usually refers to an alternator; which produces AC (alternating current). The rotating shaft rotates electromagnets surrounded by heavy copper coils wire inside generators. This creates a magnetic field which causes the electrons of the copper wire to move away from atom to atom that generates electricity. The voltage produced by a generator depends on the number of windings magnetic force and magnetic velocity turns. There are several steps involved in creating a fan with generated electricity harnessed from Dynamo. The first is to create a program that uses Dynamo to provide instructions that are programmed on the Dynamo board to facilitate user interaction.

Advanced Fault Detection in Power Systems Using Wavelet Transform: SIMULINK-Based Implementation and Analysis

Saiful Islam Tuhin — 2024-04-23

Traditional methods struggle to find faults in power transmission lines. This paper presents an approach for short transmission lines, leveraging the power of wavelet transforms. Traditional methods analyze time-domain signals, limiting their ability to differentiate fault transients. Wavelet transforms, offering a combined time-frequency analysis, provide a deeper understanding of these transients. A detailed short transmission line model is built in SIMULINK. Diverse fault scenarios are meticulously simulated, and current signals undergo wavelet transform analysis. Key features extracted from the wavelet coefficients act as fingerprints of potential faults. These features are then utilized to develop a robust fault detection algorithm specifically designed for short transmission lines. The proposed method promises enhanced fault detection capabilities compared to existing techniques in this domain. The results, presented in subsequent sections, will shed light on the effectiveness of wavelet transforms in empowering smarter and more reliable transmission line operations.

Electronic Band Structure and Fermi Surface Analysis of Ce2 Ni1-Xcoxge2: A Pseudo Potential Study

Ataman O. J — 2024-05-14

This study uses pseudopotential calculations to investigate the electronic band structure and Fermi surface properties of Ce2Ni1-xCoxGe2 alloys. The research problem centers on understanding the effects of Co substitution on the electronic properties of these alloys, particularly regarding potential high-temperature superconducting behavior. The methodology involves density of states (DOS) analysis and Fermi surface calculations for Ce2Ni1-xCoxGe2 alloys with varying Co concentrations. Results reveal a notable increase in DOS around the Fermi level with increasing Co substitution, indicative of enhanced metallic behavior and potential superconducting characteristics. Additionally, band structure analyses demonstrate the significant role of hybridization between Ce 4f, Ni/Co 3d, and Ge 4s/4p orbitals in determining electronic behavior. Fermi surface calculations unveil a transition from near-spherical to complex 2D and 3D shapes with higher Co concentrations, suggesting modifications in Fermi energy surface nestings or electron scattering. This study's conclusions emphasized the intricate electronic structure of Ce2Ni1-xCoxGe2 alloys and highlighted the potential for further exploration in high-temperature super conductivity research.

Building an Efficient Land Information System in Ghana: Insights from Land Governance

Priscilla Badaweh Coffie — 2024-05-14

Land governance is a linchpin for sustainable socioeconomic development and the protection of property rights in Ghana. Efficient land resource management is essential for fostering equitable access to land and ensuring the well-being of citizens. This study aims to explore the multifaceted landscape of land governance in Ghana and inform the development of an efficient Land Information System (LIS). Drawing from international perspectives and the legal framework of Ghana, this research unveils the complexities, challenges, and opportunities inherent in the land governance system of the country. The study delves into thirteen (13) key areas requiring attention and improvement, spanning legal frameworks, land surveying, digital technology adoption, decentralization, transparency, capacity building, public awareness, data security, collaboration, customary land systems, conflict resolution, regular updates, and financial sustainability. By dissecting these components, the research highlights the intricate interplay between effective land governance and the role of an efficient LIS. The study provides valuable insights and recommendations for policymakers, government agencies, and stakeholders, with the intent to enhance land governance practices and build effective LIS in Ghana. This study also contributes to the realization of a more transparent, accessible, and equitable land management system that aligns with the development aspirations of the nation. This study also serves as a roadmap for fostering sustainable growth, bolstering land tenure security, and driving positive institutional change in the land governance landscape of Ghana.
