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.

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.
3. (i) Research
The systematic, rigorous investigation of a situation
or problem in order to generate new knowledge or
validate existing knowledge.

For example, applied researchers may investigate ways to:
• Improve agricultural crop production
• T

Basic (aka fundamental or pure ) research is driven by a scientist's curiosity or interest
in a scientific question. The main motivation is to expand man's knowledge, not to
create or invent something. There is no obvious commercial value to the discoveries that
result from basic research.
For example, basic science investigations probe for answers to questions suchas:
• How did the universe begin?
• What are protons, neutrons, and electrons composedof?
• What isthe specificgeneticcode of the fruit fly?

Correlational research refers to the systematic investigation or statistical study
of relationships among two or more variables, without necessarily determining
causeand effect.
For example, to test the hypothesis “ Listening to music lowers blood pressure
levels” there are 2 ways of conducting research
• Experimental – group samples and make one group listen to musicand then compare
the bp levels
• Survey – ask people how they feel ?How often they listen? And then compare

Descriptive research refers to research that provides an accurate portrayal of
characteristics of a particular individual, situation, or group. Descriptive research, also
known as statistical research.
These studies are a means of discovering new meaning, describing what exists,
determining the frequency with which something occurs, and categorizing
information.
For example,
• finding the most frequent disease that affects the children of a town.

Ethnographic research refer to the investigation of a culture through an in-depth study of the
members of the culture; it involves the systematic collection, description, and analysis of data for
development of theoriesof cultural behavior.
It studies people, ethnic groups and other ethnic formations, their ethno genesis, composition,
resettlement, social welfare characteristics, as well as their material and spiritual culture.
The purpose of ethnographic research is to attempt to understand what is happening
naturally in the setting and to interpret the data gathered to see what implications could be
formed from the data.

On a broader perspective, all researches can be classified into two
basic approach to research:
• Qualitative Approach
• Quantitative Approach
12. Qualitative Approach
Qualitative approach is research dealing with phenomena that are difficult or
impossible to quantify mathematically
, such as beliefs
, meanings
, attributes
,
and symbols.
Qualitative research techniques include focus groups, interviews, and observation
(1. to uncover pattern, trends; 2. insight for hypothesis; 3. understand reason and
motivation)
Ex : How was your experience today? Ans: great, fine, boring and terrible
How is the feedback so far ?
13. Quantitative research
Quantitative approach refers to the systematic empirical
investigation of any phenomena via statistical, mathematical
or computational techniques. It is further sub classified in to
Inferential approach
Experimental approach
Simulation approach
14. Quantitative Approaches
Inferential Approach
Infer characteristic or relationship of population from
sample. For ex: what is the average height of dehradun
people?
Experimental Approach
Some variables are manipulated and observed their effect
on other variables. Ex: BPlevel measure (listening music)
15. Quantitative Approaches
Simulation Approach
Simulation is the imitation of operation of real world process
or system over time.
Useful to represent operation of real world system and its
dynamic process.
Useful for understanding future condition of system.
So many application like queuing at work, staffing
requirements etc.
