What is a Dynamo Generator?

A Dynamo-generators, often referred to as simply a dynamo or generator, is a device that converts mechanical energy into electrical energy. It operates on the principles of electromagnetic induction, discovered by Michael Faraday and Joseph Henry in the early 19th century. These generators are widely used in various industries, ranging from power plants to portable devices, providing a reliable source of electricity.

Understanding the basics

At its core, a Dynamogenerators consists of two essential components: a stationary magnetic field and a rotating armature. When the armature rotates within the magnetic field, it generates an electric current. This current can then be harnessed for various purposes, such as powering lights, motors, and electronic devices.

Components of a dynamo generator

A typical Dynamogenerators comprises several key components, including:

  1. Armature: The rotating part of the generator, consisting of conductive coils or windings.
  2. Magnetic field: The stationary field created by permanent magnets or electromagnets.
  3. Brushes and Commutator: Brushes are responsible for transferring the generated electricity from the armature to an external circuit, while the commutator ensures a continuous flow of current.
  4. Shaft and Bearings: The shaft allows the armature to rotate, while bearings provide smooth movement and reduce friction.

Principles of Electromagnetic Induction

To comprehend the working of a Dynamogenerators, it is essential to understand the principles of electromagnetic induction. Electromagnetic induction refers to the generation of an electric current in a conductor when exposed to a changing magnetic field.

Explaining electromagnetic induction

According to Faraday’s law of electromagnetic induction, a voltage is induced across a conductor when the magnetic field through it changes. This voltage, often referred to as electromotive force (EMF), is responsible for the generation of electric current in the dynamo generator.

Relationship between magnetic fields and electrical currents

The strength of the induced current depends on various factors, including the rate of change of the magnetic field, the number of turns in the armature coil, and the resistance of the circuit. Understanding this relationship allows us to optimize the design and efficiency of dynamo generators.

How Does a Dynamo Generator Work?

Now that we have grasped the underlying principles, let’s delve into the step-by-step process of how a Dynamogenerators works.

Step 1: Magnetic field creation

A dynamo generator relies on the presence of a magnetic field. This field can be produced using either permanent magnets or electromagnets. The stationary field interacts with the rotating armature to induce an electrical current.

Step 2: Rotation of the armature

The armature, usually in the form of a coil or multiple coils, is mounted on a shaft. As the shaft rotates, the armature also spins within the magnetic field, causing the magnetic flux to cut across the coil(s). This cutting of magnetic lines of force induces a voltage across the armature.

Step 3: Generation of electrical current

The induced voltage in the armature causes an electric current to flow through the coils. This current can be harnessed by connecting external circuitry to the generator. The brushes and commutator ensure that the current flows in a single direction, converting mechanical energy into electrical energy.

NASA propulsion technology brings flying cars closer to reality




NASA propulsion technology brings flying cars closer to reality

Anyone who’s seen Blade Runner or The Jetsons knows that flying cars are essential to the “future,” but despite many people’s expectations, these flying cars Personal vehicles have always seemed a step ahead of what they are now. Now, one company says it holds the key to making these amazing flying machines a reality, and it’s based on a NASA-proven propulsion system that won’t be abandoned easily.

Applied eVTOL Concepts this week announced plans for a vertical take-off and landing (VTOL) vehicle, the Epiphany Transporter. The company says it has a top speed of 160 mph (258 km/h), but generates less than 55 km/h. h./h. decibels of noise at 50 feet (15 meters). This is somewhere between the volume of pouring rain (50 dB) and the volume of normal human speech (60 dB).

The secret seems to be the ducted motors on the sides and rear of the Epiphany Transporter. This motor, discovered in 2002 by researchers at NASA Ames Research Center, produces great thrust, the physical force that powers jet engines and helicopters.

This duct design also has the added benefit of protecting the rotating blades within the duct that generate the thrust. Rob Bulaga, his Epiphany Transporter project engineer at Applied eVTOL Concepts, is a co-author of the original paper. The design has been refined over the 20 years since it was first tested in Ames, and Michael Moshir, founder of Applied eVTOL Concepts, said the technology has improved since the concept was flying cars first tested in a NASA wind tunnel. I believe we have made significant progress.

We have complete confidence in the ability of our patented and field-proven air ducts and advanced aircraft designs to perform as expected in flight,” said Mosher, who is also the company’s CEO and principal designer. Stated. statement.

The ship is designed to accommodate her two passengers and their luggage. The company says the Epiphany is roughly the size of a Tesla Model S and fits in a typical one-car garage.

Of course, just because a company’s ducted engine works fine in a wind tunnel doesn’t mean we’ll have flying cars anytime soon. Over the years, many vertical take-off and landing companies have come and gone, certainly including his NASA engineers.

However, it’s always sound engineering practice to use a proven design as a basis, so perhaps this will end up being the real deal.

Experts say building the giant bioreactors needed to mass-produce raw materials to make medicines, vaccines, cultured meat and more will require significant infrastructure and funding.

Matt Anderson-Baron, co-founder and CEO of Canadian company Future Fields, told TechCrunch that 10 billion liters of biodigesters will be needed by 2030, compared to the amount that exists today. said only 61 million liters.

Furthermore, recombinant proteins, which are the products of bioreactors, account for a large portion of the costs associated with cultured meat production, which may be part of the reason why the cultured meat sector has not been able to achieve price parity with traditional meat. It has become.

Future Fields believes it has discovered a more cost-effective and sustainable way to do this using EntoEngine. This is an approach that uses fruit flies rather than giant steel tanks to produce recombinant proteins.

“Traditionally, growth factors and recombinant proteins are produced in microbial systems grown in large stainless steel tanks, so they compete for the same infrastructure,” Anderson-Barron said. “We are replacing bioreactors with insects. We are genetically engineering insects that can be raised in simple plastic containers. This is highly scalable, cost-effective, and important. Best of all, it avoids infrastructure-related issues and frees up the supply chain for people who don’t have to create more demand, whether they actually need it or not.”

Anderson Barron, his wife Jarin Anderson Barron, and co-founder Reiji Ghafoor have been working on the issue for some time (the last time they covered Future Fields was in 2020. ), the company today announced that the facility will be used to launch its first products beyond cultivated meat (research, cell therapy, biopharmaceuticals) and to expand its team.

Bee Partners is joined by Toyota Ventures, Builders VC, AgFunder, Amplify Capital, BoxOne Ventures’ Milad Alukozai, Green Circle Foodtech, Siddhi Capital and Climate Capital in the round.

Anderson Barron declined to disclose growth rates, but said the team has doubled in size in the past year and has supplied more than 60 companies with animal protein products in the past 18 months.

Future Fields is building its first manufacturing facility near its headquarters in Edmonton, Canada, which will produce kilograms of recombinant protein in just 10,000 square feet of manufacturing space.

Meanwhile, the company’s EntoEngine technology will expand its portfolio of human recombinant protein products for medical research and biopharmaceuticals, including five of his proteins useful in wound healing, reproductive biology, muscle and breast milk development, and stem cell research. Offers.

Anderson-Baron said using flies offers both speed and scalability. EntoEngine’s Drosophila technology allows him to produce biomass 16-30 times faster than conventional bioreactors, producing protein every day in the same space and infrastructure.

“This is not possible with other systems that have bioreactors that run frequently for weeks and run one production cycle,” he added. “This gives us a lot more flexibility and, importantly, it allows us to scale much faster and at a lower cost, as it replaces stainless steel tanks that require insects to be plugged into the wall.”

(ADINet, Thai Meteorological Department, media)(ECHO Daily Flash of 17 Aug 2023)

Libraries are gradually moving from their previous role as ADINet “repositories” of knowledge to organizational centers for information exchange. Knowledge stored in the form of rare books, journals, other information materials and modern electronic resources is displayed in the library for users. The boundaries of libraries are expanding beyond their four walls and library professionals are preparing to take on the challenge of using libraries to disseminate authentic, relevant and correct information to their patrons.

Thanks to rapid progress in all fields, more and more documents are becoming available worldwide in both print and electronic formats. No library can afford to store all the documents needed for a user’s area of interest, but they can provide users with a “link” to find the information they need. Thus, networking and resource sharing have now become very important and such solutions are effectively provided by ADINET to users and librarians of all fields of knowledge and are widely used throughout the world.

In recent days, severe storms and strong winds have affected central and northern Thailand, especially the provinces of Phetchaburi, Chiang Mai, Surat Thani, Satun and Rayong, causing casualties and damage.

Media reported that as of August 16, one person was ADINet killed, one was missing and five people were rescued in a weather-related incident that occurred on August 12 in Bang Laem district in northeastern Phetchaburi province.

In addition, according to the ASEAN Disaster Information Network (ADINet), on August 16, 200 people and about 400 houses were affected by flooding in the provinces of Chiang Mai, Surat Thani, Satun and Rayong.

More heavy rain and thunderstorms are expected in ADINet most parts of the country over the next 24 hours, with some very heavy rain expected in northern Thailand.

Retinal diseases include many different types, including varying diseases and degrees of severity. It is not practical to train models with different types of diseases. When new patients with a disease appear, the model must be dynamically trained. Although deep learning methods have received a lot of attention in recent years, they suffer from fatal forgetting when performance drops significantly when a new training class is introduced. We found that maintaining the feature distribution of the old model helps maintain the performance of incremental learning. In this paper, we develop a framework called Attribute-Driven Incremental Network (ADINet), a novel architecture that integrates class label prediction and attribute prediction into an incremental learning framework to improve classification performance. Image-level classification uses knowledge distillation (KD) to preserve knowledge about base classes. Attribute prediction calculates weights for each image attribute and uses these weights to make more accurate attribute predictions. Design attribute distillation (AD) loss to preserve image information. When a new class is introduced, the attributes of the base class are learned. This additional training can be performed multiple times with some loss of performance. Experimental results on our proprietary fundus image dataset show that our proposed method outperforms existing state-of-the-art methods. To demonstrate the generalizability of our proposed method, it was tested on the ImageNet-150K-sub dataset and showed good performance.
