Root cause of Magnetic Humming due to TransformerRekaNext Capital
In Audio Design in cassettes, magnetic head picks up magnetic stray fields and cause irritating humming background noise. The 3rd harmonic of 50 Hz gets amplified when the speaker resonance coincides.
This R&D report validates the root cause. The solution was to have a physcial distance, while the current produced units had a wire loop to create a 150Hz pickup coil to phase cancellation manually tuned at PCB.

Learned how to convert R&D results into a working Prototype. The PhD program was supported by a U.K. SME Industrial Scholarship from Wolf Safety Lamp Co, Sheffield to develop a Portable High Speed Turbo Generator from 55 Watts to 250 Watts within the same packaging. Starting from magnetic materials of Alnico until Rare Earth Samarium Cobalt with different Rotor Design configurations at TRL3. This project was to develop a full scale TRL5 prototype suitable for the product development launch of the Turbolite Model. The design required the development of an Efficient Electric Power Generator Model, a 2 Dimensional Magnetic Field Finite Element Method (FEM) Model from Maxwell' s Equation with Numerical Methods using Fortran IV and Development of over speed protection electronic techniques. The project was successful launched into a full scale product model by the company. In their website, it is mentioned that that product help the company to grow into an international business.
Proof of Concept project for Singapore PUB Water Reclaimation Plant to track staff for both out-door and in-door. Uses ZigBee and Triangluarization to determine position. Works fairly well, but battery consumption is not good
System was operationalised first using Computer Vision, but accuracy and repeatability were not consistant, until LiDar was used. Technique used AI Numerical Methods
This is a simplified presentation about AI limitations as rarely the AI limitation is explain to people who do not have a technical background. This explains why sometimes the Analytics guys keep saying " I need more Data to Train the Model"

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.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

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.
