Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
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.
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.

2. WHAT IS 3D PRINTING? - TECHNOLOGY
DEFINITION AND TYPES
• 3D printing, also known as additive manufacturing, is a
method of creating a three dimensional object layer-by-
layer using a computer created design.
• 3D printing is an additive process whereby layers of
material are built up to create a 3D part. This is the
opposite of subtractive manufacturing processes, where a
final design is cut from a larger block of material. As a
result, 3D printing creates less material wastage.
3.
4.
5. History of 3D Printing
Who Invented 3D Printing?
• The earliest 3D printing manufacturing equipment was
developed by Hideo Kodama of the Nagoya Municipal
Industrial Research Institute.
6. History of 3D Printing
When was 3D Printing Invented?
• Hideo Kodama's early work in laser cured resin rapid
prototyping was completed in 1981. His invention was
expanded upon over the next three decades, with the
introduction of stereolithography in 1984. Chuck Hull of
3D Systems invented the first 3D printer in 1987, which
used the stereolithography process
7. Types of 3D printing
Binder Jetting
• Binder jetting deposits a thin layer of powered material,
for example metal, polymer sand or ceramic, onto the
build platform, after which drops of adhesive are
deposited by a print head to bind the particles together.
8.
9. Types of 3D printing
Direct Energy Deposition
• Direct energy depositioning uses focused thermal energy
such as an electric arc, laser or electron beam to fuse wire
or powder feedstock as it is deposited. The process is
traversed horizontally to build a layer, and layers are
stacked vertically to create a part.
10.
11. Types of 3D printing
Material Extrusion
• Material extrusion or fused deposition modelling (FDM)
uses a spool of filament which is fed to an extrusion head
with a heated nozzle. The extrusion head heats, softens
and lays down the heated material at set locations, where
it cools to create a layer of material, the build platform
then moves down ready for the next layer.
12.
13. Types of 3D printing
Material Jetting
• Material jetting works in a similar manner to inkjet
printing except, rather than laying down ink on a page,
this process deposits layers of liquid material from one or
more print heads. The layers are then cured before the
process begins again for the next layer.
14.
15. Types of 3D printing
Powder Bed Fusion
• Powder bed fusion (PBF) is a process in which
thermal energy (such as a laser or electron beam)
selectively fuses areas of a powder bed to form
layer, and layers are built upon each other to create
a part.
• One thing to note is that PBF covers both sintering
and melting processes.
16.
17. Types of 3D printing
Sheet Lamination
• Sheet lamination can be split into two different
technologies, laminated object manufacturing (LOM) and
ultrasonic additive manufacturing (UAM). LOM uses
alternate layers of material and adhesive to create items
with visual and aesthetic appeal, while UAM joins thin
sheets of metal via ultrasonic welding. UAM is a low
temperature, low energy process that can be used with
aluminum, stainless steel and titanium.

20. Types of 3D printing
VAT Photopolymerization
• VAT photopolymerization can be broken down into two
techniques; stereolithography (SLA) and digital light
processing (DLP). These processes both create parts
layer-by-layer through the use of a light to selectively
cure liquid resin in a vat. SLA uses a single point laser or
UV source for the curing process, while DLP flashes a
single image of each full layer onto the surface of the vat.
21.
22.
23. How Long Does 3D Printing Take?
• The printing time depends on a number of factors,
including the size of the part and the settings used for
printing. The quality of the finished part is also important
when determining printing time as higher quality items
take longer to produce.
25. Advantages Of 3D Printing
The advantages of 3D printing include:
Bespoke, cost-effective creation of complex geometries
Affordable start-up costs
Completely customizable
Ideal for rapid prototyping
Allows for the creation of parts with specific properties
26. Disadvantages Of 3D Printing
The disadvantages of 3D printing include:
Can have a lower strength than with traditional
manufacture
Increased cost at high volume
Increased cost at high volume
Post-processing requirements
