This document describes the design and analysis of blades for a nomadic Kuroshio turbine (NKT) that harnesses energy from ocean currents. It discusses two blade design procedures, computational fluid dynamics simulations of blade performance, and comparisons to experimental data. The first procedure designs blades similar to marine propellers using lifting line and surface methods. The second uses a genetic algorithm and boundary element method to optimize blade geometry for maximum torque. Simulations show blades from both procedures meet the design goal of generating 10 kW per turbine and match experimental power outputs closely. Structural analysis also confirms blade designs meet regulatory requirements.

In this project, the primary aim is to produce optimum parameters for electric power generation via renewable sea wave energy for the Turkish sea coastlines. The modular system is composed of wave actuation mechanism, hydraulic system and generator. This system is used to model and compute the optimal parameters but also monitor the Turkish coastline characteristics. A hydrodynamic model based optimum PTO drives the generator that are further connected to other similar units to construct a wave energy farm. A testbench is created to mimic the operation of wave actuation in lab environment. This unit drives hydraulic system that can generate mechanical power to excite a generator shaft. Optimal wave actuation mechanism parameters suitable to our coastlines have been calculated. With these aims, the system designed on the basis of the mechanism that based on point absorber buoy. Initial design and hydrodynamic simulations in MATLAB/Simulink is given.
THE EFFECT OF VARIATION SKEW ANGLE B-SERIES PROPELLER ON PERFORMANCE AND CAVI...IAEME Publication
Achieving the highest possible efficiency from a propeller is needed to minimize
fuel. However, this is limited by the occurrence of cavitation, vibration, noise and
material strength possessed by propellers. Thus it is necessary to do a new
breakthrough in designing or modifying the shape of the propeller to achieve
maximum performance. One modification that can be done is to change the skew
angle. Propeller B-Series is a propeller that is often used and has a fairly complete
geometry data. Cavitation is something that must be considered because it will
manifest into noise, vibration and erosion in the propeller blade. The modification of
the skew angle will be analyzed using the CFD (Computational Fluid Dynamics)
method of how the relationship between performance and cavitation results from the
various variations that have been made. So that later it can be known that skew angles
produce maximum performance and low cavitation. From the simulation results it can
be concluded that the greater the skew angle, the value of the thrust and torque
There are abundant of wave energy converter technologies available to convert wave energy into useable energy. However, most of them are huge and suitable for large application. Thus, this paper aimed to propose portable pico generator designs for small scale application. Investigation on the performance of designs with varying halbach magnet shapes was mainly focused and discussed. Two designs of different magnet shape i.e. triangular and trapezoid were proposed. Open-circuit simulation and optimization results were obtained using Finite Element Method. From the results, it was found out that Trapezoid Magnet Design produced better performance and lower material cost compared to another proposed design, Triangular Magnet as well as conventional Rectangular Magnet shape.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
