Thermal Power Plant : Principle, Parts, Working, Advantages and Disadvantages

Basic Introduction or Principle: We all are aware with the term "Generator". A device which converts mechanical energy into electrical energy is known as generator. This generator makes rotate with the help of some kind of external energy. When this energy extract from the energy of steam, the plant is known as steam power plant.  A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a  boiler   which converts it into high pressurized super heated steam. This high energized steam passes through steam  turbine  (a mechanical device which converts flow energy of fluid into mechanical energy) and rotate it. Owing to extract full energy of steam, three stage turbines is used which is known as LPT (Low pressure turbine), IPT (intermediate pressure turbine) and HPT (High pressure turbine). The turbine shaft is connected to the generator rot

Nottingham students develop 3D selfie software

PhD researchers at Nottingham University have developed a software programme that can turn a flat 2D image into a 3D selfie.

Their web application allows users to upload a single colour image, then transforms it into a 3D image that shows the physical shape of the face. It works using a Convolutional Neural Network (CNN) – artificial intelligence (AI) that applies machine learning which has been trained on a huge dataset of 2D pictures and 3D facial models. As well as being able to reconstruct 3D facial geometry, the CNN can also make predictions regarding the non-visible parts of the face.
“Our CNN uses just a single 2D facial image, and works for arbitrary facial poses [front or profile images] and facial expressions [smiling],” said Nottingham PhD student Aaron Jackson, the paper’s lead author.
According to the team, current techniques to create a 3D representation require multiple facial images, and face several challenges such as dense correspondences across large facial poses, expressions and non-uniform illumination. By applying neural networks, the Nottingham researchers believe they have found a more straightforward solution to these complex rendering problems.

“The main novelty is in the simplicity of our approach which bypasses the complex pipelines typically used by other techniques,” said research supervisor Dr Yorgos Tzimiropoulos. “We instead came up with the idea of training a big neural network on 80,000 faces to directly learn to output the 3D facial geometry from a single 2D image.”
As well as facial and emotional recognition applications, the 3D selfie software could be used to simulate the results of plastic surgery, or assist medical professionals in understanding conditions like autism. The technology could also help improve augmented and virtual reality and has potential for character personalisation within computer games.

New imaging technique could detect acoustically 'invisible' cracks

The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems. The nonlinear acoustic technique developed by researchers from the University of Bristol's Ultrasonics and Non-destructive Testing (NDT) research group is published in the current issue of  Physical Review Letters  together with an accompanying article in  Physics . It has long been understood that acoustic nonlinearity is sensitive to many physical properties including material microstructure and mechanical damage. The lack of effective imaging has, however, held back the use of this important method. Currently engineers are able to produce images of the interior of components using ultrasound, but can only detect large problems such as cracks. This is like detecting only broken bones in a medical environment. Imaging of acoustic nonlinearity is achieved by exploiting differences in

Main Parts of an Internal Combustion Engine

Today we will learn about main parts of an engine. An internal combustion engine is the engine in which combustion (burning of fuel) takes place inside the cylinder of engine. By burning of the fuel high temperature and pressure force generates. This pressure force use to move the vehicle or rotate wheels by use of some mechanism. In an engine many parts work together and achieve the goal of converting chemical energy of fuel into mechanical energy. These parts are bolted together and the combination of all these parts is known as engine. Today I am going to tell you about these parts and how they work so you can know the basic of automobile engine. Main Parts of an Internal Combustion Engine: 1. Cylinder block Cylinder is the main body of IC engine. Cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. The main function of cylinder is to guide the piston. It is in direct contact with the products of combustion so it must b

Pedal Operated Hacksaw

Pedal Operated Hacksaw Operating a hacksaw manually is a very tiring and time consuming task. It requires a lot of manual effort and delivers uneven cutting. Operating a electrical hacksaw does deliver good results but consumes a lot of energy. So here we propose a semi automated hacksaw using pedal power. Here we design and fabricate a hacksaw that is run by pedal power and achieves even cutting with very less efforts. Here we use a chain sprocket arrangement to transfer power from pedals to hacksaw. A strong and firm base frame allows for efficient power transfer between the system. We use bearings and mounts to mount and setup the entire system and ensure a smooth circular motion of pedals. Now we attach a hub to the other sprocket. This hub is connected with a connecting rod which moves with the hub in order to produce a lateral motion. We now develop a supporting frame and connect a saw to the other end in order to achieve desired cutting movement of saw. We also attach
