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.
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.
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.

1. La Ley de Ohm
www.capacity.cl – contacto@capacity.cl
2. El físico alemán George Ohm (1789-1854), determinó que
para que exista una corriente eléctrica que circule por un
conductor, es necesario que exista una tensión eléctrica
en sus extremos; en consecuencia, debe existir una
relación entre la tensión a la que es sometido un circuito
y la intensidad de corriente que circula por él.
Estableciendo una analogía entre una corriente eléctrica
y una de líquido, Ohm descubrió que la intensidad de la
corriente era directamente proporcional a la tensión, si se
trata de un circuito completo o, en el caso de un
conductor, a la diferencia de potencial entre sus
extremos; algo similar a lo que sucede en una cañería de
agua en que el caudal es proporcional a la diferencia de
presión entre los extremos de la parte considerada.
Ley de Ohm
3. La Ley de Ohm relaciona las magnitudes de voltaje, resistencia e intensidad de la siguiente manera.
La intensidad de corriente que circula por un circuito eléctrico es directamente proporcional a la diferencia
de potencial (V) o tensión del mismo e inversamente proporcional a la resistencia que presenta.
Con esta expresión vas a ser capaz de calcular en un circuito una magnitud a partir de las otras dos.
Ley de Ohm
Donde; I: Intensidad que se mide en amperios (A).
V: Voltaje que se mide en voltios (V).
R: Resistencia que se mide en ohmios (Ω).

4. Para calcular la intensidad calculamos directamente la fracción anterior.
Para calcular el voltaje, vamos a deshacer la fracción, pasando R que está dividiendo al otro lado de la
igualdad multiplicando. Nos queda:
Ahora, si queremos calcular R, en la expresión anterior pasamos la I que está multiplicando al otro lado de la
igualdad dividiendo, aislando así R. Nos queda:
