The Pneumatics is study of mechanical motion caused by pressurized gases and how this motion can be used to perform engineering tasks.
Pneumatic systems operate on a supply of compressed air which must be available in sufficient quantity and the air used in pneumatic devices is dried and free from moisture so that it does not create any problem to the internal parts of the system and avoid corrosive actions too.
The compressed air is delivered by the compressor which is a machine that takes in air or gas at a certain pressure and delivered the air at a high pressure.
This machine is pneumatic powered machine and electrical energy is used to operate which has low co-efficient of friction and air.
This machine is designed in solid-works software (module 2017).
This chapter introduces Basics of Pneumatics, Advantages & Disadvantages, Application and symbols to students who are taking Pneumatics and Hydraulics course in Polytechnics

Fabrication of Semi-Automatic Molten Metal Pouring System in Casting Industries.IJERA Editor
In India there are many foundry have followed conventional and manual operations. Today’s competitive
environment has lower manufacturing cost, more productivity in less time, high quality product, defect free
operation are required to follow to every foundry man. Mould shifting, Crushing, Lower Surface finish,
Shrinkage, Porosity, Cold shut and Extra material are common casting defects due to these manual operations.
These defects directly affect on productivity, profitability and quality level of organization. In the current global
competitive environment there is a need for the casting units and foundries to develop the components in short
lead time. Defect free castings with minimum production cost have become the need of foundry. In any casting
industry the leading problem taking place is Mould shifting from electrical furnace to the die casting. In the
present work an attempt was made to fabricate the pneumatic system for pouring the molten metal in to the
cavity semi automatically. The system was tested for carrying the metal which reduces the manual work for
mould shifting from electrical furnace to die casting and the results are compared with manual working which
improves the quality, productivity and defect free product

As the name suggests industrial centrifugal fans are heavy-duty blowers or air flow devices manufactured for manufacturing, production, or industrial purposes. The materials used in these fans are extremely durable. Since these fans operate in extremely harsh environmental conditions, they are robust enough to maintain constant pressure and flow of air. The materials used in centrifugal fans make them strong.

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.

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.

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.
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
Understanding Inductive Bias in Machine LearningSUTEJAS
