PSEUDOCODE TO SOURCE PROGRAMMING LANGUAGE TRANSLATORijistjournal
Pseudocode is an artificial and informal language that helps developers to create algorithms. In this papera software tool is described, for translating the pseudocode into a particular source programminglanguage. This tool compiles the pseudocode given by the user and translates it to a source programminglanguage. The scope of the tool is very much wide as we can extend it to a universal programming toolwhich produces any of the specified programming language from a given pseudocode. Here we present thesolution for translating the pseudocode to a programming language by using the different stages of acompiler
We have learnt that any computer system is made of hardware and software.
The hardware understands a language, which humans cannot understand. So we write programs in high-level language, which is easier for us to understand and remember.
These programs are then fed into a series of tools and OS components to get the desired code that can be used by the machine.
This is known as Language Processing System.

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.

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.
2. Computer programs are generally written in high-level
languages (like C++, Python, and Java). A language
processor, or language translator, is a computer program that
convert source code from one programming language to
another language or human readable language
A compiler is a program that can read a program in one
language i.e the source language and translate it into an
equivalent program in another language which is the target
language.
A compiler

5. What Is an Interpreter?
It is a program that functions for the
translation of a programming language into a
comprehensible one.
It is a computer program used for converting
high-level program statements into machine
codes. It includes pre-compiled code, source
code, and scripts.
An interpreter translates only one statement
at a time of the program.
They create an exe of the programming
language before the program runs.

7. Lexical Analysis: Lexical analysis or Lexical
analyzer is the initial stage or phase of the
compiler. This phase scans the source code and
transforms the input program into a series of a
token.
A token is basically the arrangement of
characters that defines a unit of information in
the source code.
NOTE: In computer science, a program that
executes the process of lexical analysis is
called a scanner, tokenizer, or lexer.
8. •To read the input character in the source code and produce a token is
the most important task of a lexical analyzer.
•The lexical analyzer goes through with the entire source code and
identifies each token one by one. The scanner is responsible to
produce tokens when it is requested by the parser.
•The lexical analyzer avoids the whitespace and comments while
creating these tokens. If any error occurs, the analyzer correlates
these errors with the source file and line number.
9. There are three terminologies-
Token
Pattern
Lexeme
Token: It is a sequence of characters that
represents a unit of information in the source
code.
Pattern: The description used by the token is
known as a pattern.
Lexeme: A sequence of characters in the
source code, as per the matching pattern of
a token, is known as lexeme. It is also called
the instance of a token.
10. The lexical analyzer performs the following
tasks-
The lexical analyzer is responsible for
removing the white spaces and comments
from the source program.
It corresponds to the error messages with the
source program.
It helps to identify the tokens.
The input characters are read by the lexical
analyzer from the source code.
