Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

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.

2. GROUP TECHNOLOGY (GT)
GT is a manufacturing philosophy in which similar parts are
identified & grouped together to make advantage of their similarities
in design and production.
Similar parts bare arranged into part families, where each part family
possesses similar design and/or manufacturing characteristics.
Grouping the production equipment into machine cells, where each
cell specializes in the production of a part family, is called cellular
manufacturing
3. Part Families
• Part family - Group of similar parts
• Part family is a Collection of parts that are similar either because of
geometric shape and size or because similar processing steps are
required in their manufacture.
• Machine cell - Group of machineries used to process an individual part
family
4. Part Families
Similar prismatic parts requiring similar milling operations
Dissimilar parts requiring similar machining operations (hole drilling, surface milling)
Identical designed parts requiring completely different manufacturing processes
5. METHODS FOR PART FAMILY
There are three general methods for solving part families grouping.
All the three are time consuming and involve the analysis of much of
data by properly trained personnel. The three methods are:
Visual inspection.
Parts classification and coding.
Production flow analysis.
6. Visual Inspection Method
• The visual inspection method is the least sophisticated and least expensive method.
• It involves the classification of parts into families by looking at either the physical parts or their
photographs and arranging them into groups having similar features.
10. Parts Classification and Coding Method
• In parts classification and coding, similarities among parts are identified, and these
similarities are related in a coding system.
• Two categories of part similarities can be distinguished:
1. Design attributes, which concerned with part characteristics such as geometry,
size and material. (Basic external and internal shape Rotational or rectangular
shape, L/D ratio, Aspect ratio, Dimensions and Tolerances)
2. Manufacturing attributes, which consider the sequence of processing steps
required to make a part.(Major processes, Minor operations, Operation sequence,
Dimension, Surface finish, Machine tool Production cycle time)
• There are three basic code structures used in group technology
– Monocode or hierarchical code
– Polycode or attribute
– Hybrid or mixed code
11. Monocode or Hierarchical code
In which the interpretation of each successive symbol depends on the
value of the preceding symbols.
12. Polycode or Attribute Code
• In which the interpretation of each symbol in the sequence is always the
same, it does not depend on the value of the preceding symbols.
13. Hybrid or Decision Code
• Construction to combine the best features of monocodes and
polycodes
• Best examples of a hybrid code is the opitz code and classification
system
14. OpitzClassificationSystem (H.opitz university of Aachen in Germany)
Form Code 1 2 3 4 5 for design attributes
Supplementary Code 6 7 8 9 for manufacturing attributes
Secondary Code A B C D for production operation type & sequence
17. Example: Opitz part coding System
• Given the rotational part design below, determine the form code in the Opitz parts
classification and coding system.
Solution
• Length-to-diameter ratio: L/D = 1.5 Digit 1 = 1
• External shape: both ends stepped with screw thread on one end Digit 2 = 5
• Internal shape: part contains a through hole Digit 3 = 1
• Plane surface machining: none Digit 4 = 0
• Auxiliary holes, gear teeth, etc.: none Digit 5 = 0
The form code in the Opitz system is 15100
18. Problem 2:
•Length-to-diameter ratio: L/D = 1.4 Digit 1 = 1
•External shape: stepped on one end Digit 2 = 1
•Internal shape: part contains a through hole Digit 3 = 1
•Plane surface machining: none Digit 4 = 0
•Auxiliary holes, gear teeth, etc.: radial hole Digit 5 = 3
The form code in the Opitz system is 11103
19. MICLASS System
• It stands for Metal Institute Classification system and developed by Netherlands
Organization for Applied Scientific research. It is referred as Multiclass system.
• MICLASS classification range from 1 to 30 digits. Universal code the first 12 digits
code and next 18 digits are Supplementary code
20. Production Flow Analysis (PFA)
• Production flow analysis (PFA) is a method for identifying part families and
associated machine groupings that uses the information contained on process plans
rather than on part drawings.
• Steps involved in PFA
Data collection
Sortation of process routings
Preparation of a PFA chart and
Cluster analysis
23. Cellular Manufacturing
Application of group technology in which dissimilar machines or processes
are aggregated into cells, each of which is dedicated to the production of a
part family or limited group of families
Typical objectives of cellular manufacturing:
To shorten manufacturing lead times
To reduce WIP
To improve quality
To simplify production scheduling
To reduce setup times
24. Q2. Briefly explain about the Opitz coding system used in group technology. write
any seven advantages of group technology.
