This is the Project for my Last Year.
Taxi Go is the taxi Booking system made on PHP Platform with MySQL as a Back-End.
This is a Self Made Project.
If any user want to see the Design of the Project it is given Below,
http://taxigo.890m.com/TaxiGo/
Feasibility study is to check the viability of the project under consideration. Theoretically various types of feasibilities are conducted, but we have conducted three type of feasibilities explained as under.
ECONOMIC FEASIBILITY
With the manual system the operating cost of the system is about 60 Lacks P.A.. This cost comprises salary of 25 people, stationary, building rent, electricity, water, telephone etc. But with the new system this reoccurring cost comes out to be about 20 Lacks P.A. Hence the new system is economically feasible.
TECHNICAL FEASIBILITY
The new system requires only 6 trained person to work with the system and in overall 10 people per office are sufficient. So we will identify 6 best people from existing system and train them.
As our existing system is purely manual, so we need a one time investment of Rs 4 Laks for the purchase of 7 computers, 5 Ticket printers, a laser printer, AC and networking etc. It requires 20 Lacks PA as a operating cost.
With the above details our system is technically feasible as after investing 24 Lacks in a year, the company is still saving Rs 25 Lacks PA.
OPERATIONAL FEASIBILITY
The new solution is feasible in all sence but operationally it is not. The new system demands the expulsion of at least 15 people from the company. It creates an environment of joblessness and fear among the employees. It can lead to an indefinite strike in the company also. So the management must take corrective actions prior in advance in order to start the further proceedings.

Database management system by Neeraj Bhandari ( Surkhet.Nepal )Neeraj Bhandari
A database is an organized collection of structured data stored electronically in a computer system. A database management system (DBMS) is a complex software system used to create and manage databases and properly maintain large and complex databases. A DBMS provides logical and physical views of the data and allows for different external views for different users. It also provides languages to define, manipulate and control access to the data.
The document discusses key concepts related to databases including:
1) It defines data as representations of facts, concepts or instructions that are suitable for communication, interpretation or processing.
2) A database is defined as a structured set of non-redundant information organized based on a data model, consisting of files, records and fields.
3) A database management system (DBMS) provides an interface between users and the database, allowing for data definition, manipulation and control.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.
CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

Database management:-
A database management system (DBMS) is
system software.
Creating and managing databases.
In which files are integrated to each other
The DBMS facilitates the user to create,
retrieve, update and manage data.
Importance of DBMS:-
It helps make data management more efficient
and effective.
A database management system stores, organizes
and manages a large amount of information
within a single software application.
Use of this system increases efficiency of business
operations and reduces overall costs.

Introduction of Airline Managements System:-
We used DBMS in airline management system.
First of all, we need to identify the entities, attribute
and relationships.
When we use DBMS, the record of all airport
management entities is in the same location.
We shows entities, attributes and relationships by ER
diagram.
SQL is a language which is used for applying queries.
Example we applying queries for insertion, deletion or
updating etc.
Benefits:-
While using DBMS, the data is independent.
It removes duplication of data.
Easy to insert, update and delete data in DBMS.
When we use DBMS, the files integrated each other.
We can secure our data by using DBMS.

Problems:-
They do not communicate at accurate time.
Duplication of Data
Data Dependency
At the Time of installation of a data base or
implementation of database we check the capacity of
the operating system if operating system cannot
capable to perform the operations we need to install
a upgrade operating system to run a database
efficiently.
Implement of DBMS:-
Analyze user environment.
Develop logical model.
Choose DBMS.
Map logical model DBMS.
Develop physical Design.
