En este informe se plantean dos formas para la construcción de un circuito que exhibe los números del 0 al 9 en una pantalla 7 segmentos: primero a través de una estructura combinacional que parte de la resolución de mapas de Karnaugh y se materializa en compuertas AND, OR y NOT; y segundo, mediante un integrado 74LS48. Para tal fin, se hacen tanto diseños en CircuitMaker como montajes sobre protoboard.

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.
Overview of the fundamental roles in Hydropower generation and the components involved in wider Electrical Engineering.
This paper presents the design and construction of hydroelectric dams from the hydrologist’s survey of the valley before construction, all aspects and involved disciplines, fluid dynamics, structural engineering, generation and mains frequency regulation to the very transmission of power through the network in the United Kingdom.

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.

Electrónica digital: Display de 7 segmentos con compuertas lógicas
1. Display de 7 segmentos con compuertas lógicas

microcontrolador16@gmail.com
Introducción
En este proyecto se desea visualizar los número del 0 al 9 en un display 7 segmentos, de acuerdo a
las posiciones de un dipswitch. Hay tres maneras de realizar este proyecto. La primera es haciendo
uso exclusivamente de compuertas lógicas. La segunda es haciendo uso de compuertas lógicas y
multiplexores. Y la última es haciendo uso de un decodificador BCD a 7 segmentos integrado. En
vista que son 10 números se usará un dipswitch de 4 posiciones. Se usará un display de cátodo
común. La disposición de los pines de un display 7 segmentos es como se muestra en la siguiente
figura. Los pines sin letra son los comunes, es decir si es de ánodo común se conecta a Vcc
(normalmente 5 voltios), y si es de cátodo común se conecta a tierra. Decodificador BCD a 7
segmentos forma 1 (compuertas lógicas). Lo primero que se debe realizar es la tabla de la verdad.
Esta se realiza de acuerdo a los segmentos que se colocan en ON para mostrar cada número en el
display.

1 dipswitch de cuatro posiciones DIP-4
4 resistencia de 1k 1/4w
7 resistencias de 330ohms 1/4w
Ya con la tabla de la verdad pasamos a realizar los mapas de Karnaugh. Como son 7 salidas,
entonces son 7 mapas. Además se hará, de ser posible el uso de compuertas AND, OR, NOR,
NAND, XOR y XNOR, la razón es que implementar el circuito es más sencillo, disminuyendo el
número de circuitos integrados usados.
