I propose to apply Systems development method utilizing Reverse modeling and Model-based Simulation(SRMS), in order to solve the issues of derivational development. Derivational development is a development method for developing derived products based on products already been released. Many organizations developing embedded system have been applying derivational development to improve development efficiency, time-to-market, and product quality.
However, applying derivational development to large-scale embedded systems in a traditional way to performanec requirements of higher functionality is of high risk. In addition, as requirements of embedded systems for dependability are extremely high, the dependability of development process and safety of the product must be proven by evidence. Therefore, there is a possibility to significantly inhibit the evidence of dependability on embedded systems by continuing derivational development over many years. We apply SRMS in order to solve these issues.
In this presentation, I propose a methodology to solve issues of derivational development by applying SRMS to an SoC Equipped Multi Function Peripheral/Printer. Performance evaluation and energy consumption estimation of SoC are performed in the early stages of the SoC development. Estimating the performace and the energy consumption by a high level of abstraction model-based simulation. Because at the early stages of SoC development, modeling with a high level of abstraction is required for both the system architecture of the SoC and the behavior of the System.
The proposed method is applied for an actual embedded system in an MFP - Multi Function Peripheral/Printer. Proposed method SRMS is promising to solve the issues of derivational developmnrt in the embedded system development.

"System Methodology - Holistic Performance Analysis on Modern Systems
Traditional systems performance engineering makes do with vendor-supplied metrics, often involving interpretation and inference, and with numerous blind spots. Much in the field of systems performance is still living in the past: documentation, procedures, and analysis GUIs built upon the same old metrics. For modern systems, we can choose the metrics, and can choose ones we need to support new holistic performance analysis methodologies. These methodologies provide faster, more accurate, and more complete analysis, and can provide a starting point for unfamiliar systems.
Methodologies are especially helpful for modern applications and their workloads, which can pose extremely complex problems with no obvious starting point. There are also continuous deployment environments such as the Netflix cloud, where these problems must be solved in shorter time frames. Fortunately, with advances in system observability and tracers, we have virtually endless custom metrics to aid performance analysis. The problem becomes which metrics to use, and how to navigate them quickly to locate the root cause of problems.
System methodologies provide a starting point for analysis, as well as guidance for quickly moving through the metrics to root cause. They also pose questions that the existing metrics may not yet answer, which may be critical in solving the toughest problems. System methodologies include the USE method, workload characterization, drill-down analysis, off-CPU analysis, and more.
This talk will discuss various system performance issues, and the methodologies, tools, and processes used to solve them. The focus is on single systems (any operating system), including single cloud instances, and quickly locating performance issues or exonerating the system. Many methodologies will be discussed, along with recommendations for their implementation, which may be as documented checklists of tools, or custom dashboards of supporting metrics. In general, you will learn to think differently about your systems, and how to ask better questions."

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.

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.

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.
