Studying & Evaluating the Performance of Solar Box Cookers (Untracked)ijceronline
The primary aim of this study was to conduct the performance evaluation on solar cooker design. The secondary aim was to build and developing of a new and efficient solar cooker design. A direct solar box cooker (Untracked type) was tested in this study with low cost feature and low technology. The testing for the solar box cooker was conducted at the top roof of Material Engineering Department building. In this test, three water quantities (1.5, 1 and 0.5 kg) were used in order to find the effect of the mass quantity of cooking food on the temperature rise inside the solar cooker. The results showed that the attainable temperature reached a maximum cooking temperature of (81.6 oC) for water mass quantity of (1000 grams) with temperature difference between the cooking temperature and the ambient temperature of (61.5 oC). But a lower maximum temperature (81.7 oC) for (500 grams) the reason for that is due the lower solar intensity during the test of partially cloudy day. As a conclusion, it was found that as the solar intensity increases the cooking temperature increases too. The other factor which influences the cooking temperature is the cooking mass as the cooking mass increases the cooking temperature decreases. Although the cooking temperature increases but the standardized Power decreases, this is because the increasing in cooking temperature is not equalizing or go in parallel with the decreasing in cooking mass, thus it is preferable to use solar cooker for adequate cooking mass quantity to get a high merit or advantage solar cookers.

Hybrid cookstoves combine solar energy with fuels and electricity to achieve renewability. Total
system efficiency, which includes the efficiencies of energy production, transportation and end-use, is a better
indicator of the cooking life cycle. Electric cooking depicts low total system efficiency despite having the highest
end-use efficiency (about 80%) due to low efficiency of electricity production and transportation. In contrast, the
total system efficiency of solar cooking equals its end-use efficiency. Recent advancements in solar cookstoves
have shown efficiencies up to 35–40% with direct and 63–69% with indirect solar cookstoves. The present review
also identifies directions for future research. Specifically, the gaps in hybrid cookstove literature call for future
research to develop sustainable cooking technologies.

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.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

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.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
