What is learning rate in neural network?
The learning rate is a constant in the algorithm of a neural network that affects the speed of learning. It will apply a smaller or larger proportion of the current adjustment to the previous weight. The higher the rate is set, the faster the network will learn, but if there is large variability in the input the network will not learn very well if at all.
There are many types of antennas, to many to mention, here is a list of the most commonly used:
Unidirectional Types:
First the most common is the, 1/4 wave whip.
Following types is popular for CB and Ham
The 1/2 wave dipole, two 1/4 wave wires or whips in line and center fed
1/2 wave folded dipole, two 1/2 wave wires inline folded back to the center also used for FM reception.
1/4 wave ground plain, a 1/4 wave whip with 3 or more horizontal ground plain elements (Balanced)
1/2 wave ground plain, a 1/2 wave whip with 3 or more horizontal ground plain elements (Balanced)
5/8 wave ground plain, a 5/8 wave whip with 3 or more horizontal ground plain elements but it need L/C turning where the transmission line enters the antenna at the bottom to balance it
Semi Directional
The radio ham's use the long wire antenna for long wave medium and short wave, it is a full wave length of wire, spanned horizontal between two poles or even trees or buildings center or end fed where the transmission line is connected to the center or the end of the wire.
The inverted V, is two 1/2 or 1/4 wave wires spanned from the top of a pole in an inverted v and anchored to the ground.
Directional types:
Multi element Yagi, very popular with radio ham's and TV reception
The quad loop, or cubical quad, also popular under radio ham's
The helical coil that is very popular in the higher frequency range because of it's compactness.
The Parabolic disk that is used mostly for WiFi, microwave and satellite communication
The Printed PCB loop that is used in remote controls and cell phones, it is a printed track on the PCB in many configurations and shapes, it is also used for blue tooth dongles Etc.

The robots in industry can help reduce manufacturing cost, increase efficiency and productivity as well as standardising goods to the same quality for a long period of time continuously. Human labour can also be prevented for boring, repetitive and dangerous tasks, and is only necessary for making initiative decisions such as quality control.
What role does computer programming play in robotics?
The computer looks up and calculates the information for the robot to use through it's system. However, this is only my opinion.
Here's one thing they do, and it's an elaboration of the above idea: Think of the thermostat in your home (assuming you live in an area where you need heat during the cold season). If everything is working, when the temperature goes down a little bit the thermostat sends a signal to the furnace to send heat. When the temperature goes up, the thermostat sends a signal to stop sending heat. This feedback function means that the thermostat is a servomechanism. Computers in robots act as servomechanisms in several ways.
To take an idea right out of the air, you might imagine that some robots would have to have a gyroscope, or other kind of balance device inside. When the balance system detects that the robot is going a little too far to the left, the system can send signals to appropriate parts of the robot's workings in order to correct the robot's posi
ANSWER: Computer on a robot can be just like any computer for any machine it respond to input and give out output according to a program or software embedded into the robot. The robot may be very complex with multiple loops of servo or a simple as running a motor one way or the other. The robot can be as smart as the program allowed it to be. Basically is a dumb machine which as smart as the program installed into it.
What happens when collector and base of a transistor are short?
this transistor is common emitter configurated transistor nd if emmiter nd collector both terminals are reversed bias then no current will be flowing through th terminal...
What Specifics dangers when working with pneumatic system?
The main danger is the pent up power of compressed air. If the tie rods on an air cylinder fail the end would fly off at some terrific speed whereas with an hydraulic cylinder as soon as the end came off the pressure would be gone even though it was much higher to start with.
What is a junior hacksaw used for?
The uses of a junior hacksaw are to cut things and to mould the materials into different shapes and sizes.
What is the advantage and disadvantage of robot to humankind?
Type your answerTHE ROBOT ADVANTAGE:Robots transform company after company. Here are the advantages they offer:
- BUSINESS BENEFITS:
Robots are diligent, precise, and consistent. They create high-quality products, increase production, and perfect applications. Unlike human workers, robots are tireless. They eliminate expenses such as vacation/sick leave, worker's compensation, and medical insurance. Companies benefit from having more and better goods produced.
- MANAGEMENT BENEFITS:
Robots eliminate many workplace problems. Employee productivity is no longer a concern because robots work without taking breaks, lunches, sick time. They don't waste time or call of sick. High employee turnover and unfilled positions are no longer an issue.
- EMPLOYEE BENEFITS:
Robots are taking over mundane, repetitive and dangerous jobs, allowing workers to take higher-paying operational or managerial posts. Robots protect workers from work that could be hazardous to workers' mental or physical health. In other cases, robots assist workers - making their jobs more efficient and manageable.
- CONSUMER BENEFITS:
Robots produce consistent, high-quality goods faster and cheaper. Consumers appreciate the opportunity to access better products sooner, and pay less for all this improvement.
What is the purpose of a strain gauge?
A strain gauge is used to measure the strain of an object. It was invented by the inventors Edward Simmons and Arthur Ruge in 1938. There are several types of gauges (metallic, capacitance, photo-electrics and semiconductor gauges).
What are the advantages and disadvantages of laser technology?
Laser beams are used in modern communication systems to send signal over long distances through optical fibres.
They are also used to perform bloodless surgery.
Lasers can also be used as weapons to spoil control system of aeroplanes and make them to crash with the additional feature that the cannot be detected.
You want to know about the applications of line follower robot?
One example might be in a warehouse where the robots follow 'tracks' to and from the shelves they stock and retrieve from.
A microphone is a device that converts sound as acoustical pressure waves into electrical
voltage waves. All microphones have a diaphragm, membrane, or other mechanical elements in them that vibrates sympathetically in response to the arriving acoustic wave fronts. This mechanical element acts on the electrical element to generate audio voltage.
The sensitivity of a microphone is shown in voltage per sound pressure (mV / Pa) that show the proportionality of the audio waves to the pressure waves.
To amplify sounds (make louder), the vibrations of the connected speaker's surface must increase in amplitude.
Why antenna height is at least quarter wavelength for radiating from it?
A transmitter antenna is a tuned circuit and it can be very complex and it even get more difficult at higher frequencies, if it's not a 1/4 wave length of the transmitter frequency it is un tuned and you will have some of your RF power radiated back to the transmitter, that is called SWR, for Standing Wave Ratio and it will damp the RF that is radiated from the antenna and if the SWR is to high it can damage the transmitters final stage. It don't have to be the real physical 1/4 or 1/2 wave and it can even be 5/8 of the wavelength but then a L/C circuit have to be inserted at the input side of the antenna to tune the antenna to the correct frequency one antenna can even be used for two different frequencies, then a L/C tuning circuit have to inserted at a 1/4 wave length of the higher frequency , this type of antenna is used in duplex systems, like a cell phone.
Do railway tracks get magnetised when trains run on tracks?
No, however some trains have a magnetized wheel to help grip the track.
*Added -
Electric trains do result in short term magnetizing of the train tracks. This can be seen on sharp curves where tiny rail slivers cling along in a magnetic pattern. In the US, trains do not have magnetized wheels, but rapid trainsit systems can include a track brake that uses a magnet to provide much faster braking than the wheels alone.
Why is math important to robotics engineering?
Generally speaking, math is needed in science, engineering (not just in robotics engineering), economics, finance, accounting, medicine, and practically everyday life. The difference would be whether you want to acquire more knowledge, to have a better understanding of the subject, to have a critical thinking instead of blindly accepting what others say, to advance in career and statue, to invent/innovate, to expand your boundaries, and to apply to practical uses. You don't have to be an expert in all branches in math, but it would surely be advantageous that you know some math and enough to do your job (or to pass the tests).
Robots do a lot of different jobs. Robots can be programmed to construct small assemblies of parts much faster and with better accuracy than humans, and they don't need bathroom or smoke breaks. Robots can be programmed to perform almost any repetitive task that can be broken down into small steps and performed over and over again. Many tasks that are unsafe or dangerous for humans can also be done by programmable robots, such as painting, working with explosives, and so on. The use of industrial robots has increased a lot over the past few years, and they will no doubt become even more prevalent in the future.
What process is used to study trends?
Trend analysis is a form of comparative analysis that is often employed to identify current and future movements of an investment or group of investments. The process may involve comparing past and current financial ratios as they related to various institutions in order to project how long the current trend will continue. This type of information is extremely helpful to investors who wish to make the most from their investments.
