Event Management System Vb Net Project Report.pdfKamal Acharya
In present era, the scopes of information technology growing with a very fast .We do not see any are untouched from this industry. The scope of information technology has become wider includes: Business and industry. Household Business, Communication, Education, Entertainment, Science, Medicine, Engineering, Distance Learning, Weather Forecasting. Carrier Searching and so on.
My project named “Event Management System” is software that store and maintained all events coordinated in college. It also helpful to print related reports. My project will help to record the events coordinated by faculties with their Name, Event subject, date & details in an efficient & effective ways.
In my system we have to make a system by which a user can record all events coordinated by a particular faculty. In our proposed system some more featured are added which differs it from the existing system such as security.
Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

girder which delivers the reactions to the structural column ( heavy loads and big bays)
The crane girders are made of I (IPE) and build up sections for smaller bays and lighter cranes (6 m,
Q=50...100 kN). For bigger bays and lifting capacities of the cranes (9…12 m, Q200 kN) build-up cross
sections are used .

uniform distributed loads on the length of the girder [kN/m];
1) estimated characteristic value of the weight of the crane girder,
extracted from tables of hot rolled sections or evaluated during the sizing
procedure; for plate girders the following value may be adopted:
2) characteristic value of the weight of the rail (including the weight of
the connections); for a square section we may determine the weight:
3) characteristic values of weights of the elements of the horizontal
girder, in the case when they are part of the runway system, for ex.
weight of the chequered steel plate or of the elements of the horizontal
lattice girder. In all the cases the weight transferred to the runway girder
is considered from half of the width of the platform, the other half being
supported by the horizontal joists attached to external flanges of the
columns.

Considering the recommendations for grouping the vertical with the horizontal loads, the following
combinations are:
Dead loads (permanent) + live loads (accompanying variable) + vertical point loads from reactions
on the wheels (basic variable);
Dead loads (permanent) + live loads (accompanying variable) + horizontal point loads from: crane
surge or crab surge or skew driving effects (as basic variables);
Dead loads (permanent) + live loads (accompanying variable) + vertical point loads from reactions
on the wheels (basic variable) + horizontal point loads from: crane surge or crab surge or skew
driving effects (accompanying variable).
RELEVANT INTERNAL FORCES AND MOMENTS IN THE GIRDER
The concentrated forces being mobile influence lines will be used to determine the maximum bending
moments, shear forces and reactions on the supports.
During the process of determination of the position of the convoy of mobile forces that will lead to the
maximum bending moments some forces may remain outside the girder length. The factors that
influence these situations are mainly the wheel spacing, a, and the width of the end carriage, aw.
