Step :- C

SEO TIPS AND TRICKS

In this picture some area is highlighted with red color, very important when you are going to post in blogger .
Now i am telling you about all so be careful when u read these steps
.

Step :- D

Post Title

Post Title in blogger
This one is the very most important section of blogger. When you are going to search any thing then search engines firstly read the post title of the page if post title matches with the search then it shows your page at first link. So it is very important to select the post title for this purpose you can use google search results more the search number more the competition , so always try to chose post title which has law search numbers in google.


Permalink in blogger


Permalink in blogger is also very very important for best seo friendly websites. So you have to chose custom permalink in blogger. It reflects your page with your post title so this good for google search result and getting top rank in search engine as well as affects the ranking factor. 


Labels in blogger 

Labels are also most important to make seo friendly site and to get more traffic. Always try to select labels which are related to your post. If you are using labels but they are not using in your post then it gives negative feedback to google search engine.So always select labels which has low competition in google search result.   
                                                                                      After this i will tell you one more thing that is related to labels and have very big roll in making seo friendly websites and to give higher traffic.


Location in blogger 

According to new updates in google search engine algorithms, locations is to be set when you are going to post. When you set location in google blogger then it gives an opportunity to your page to be show by google in google events. When you set location in post article then it gives a positive feedback to google search results, and show your page in top result in google.

Step :- F

After the step D , you have to make some changes in your html coding, Its not a big  task you have to follow some steps and in your blogger.


blogger title optimization for seo friendly site  


Follow these steps :-
  1. Blogger > Template > Edit HTML
  2. Search for the below code in the <head> section of your template
    <title><data:blog.pageTitle/></title>
  3. Replace it with the below code
    <b:if cond=’data:blog.pageType == &quot;item&quot;’>
    <title><data:blog.pageName/> | <data:blog.title/></title>

HOW TO USE A TRANSISTOR AS AN AMPLIFIER | transistor characteristics and parameters

HOW TRANSISTOR WORKS AS AN AMPLIFIER

As we know transistor is a current control device, it is used for controlling the current in electronics circuits.Transistor is an electronic device used in a circuit to control a large amount of current or voltage with a small amount of voltage or current.
Two layers sandwiching one semiconductor between two other semiconductors. Because the current is transferred across a material that normally has high resistance (i.e. a resistor), it was a "transfer-resistor" or transistor.
The first practical  transistor was made  in 1948  by Shockley,

How a transistor works

for understanding how a transistor works, you have to understand how semiconductors react to an electric potential. Some semiconductors will be n-type, or negative, which means that free electrons in the material drift from a negative electrode (of, say, a battery it's connected to) toward the positive.

                                                                                     Now, we are taking the example of  a npn transistor. Each end of the transistor is an n-type semiconductor material and between them is an p-type semiconductor material. If you picture such a device plugged into a battery, you'll see how the transistor works:
  • We are taking npn transistor because of in this the mobility of charge carriers is high as compare to PNP transistor.
  • the n-type region attached to the negative end of the battery helps propel electrons into the middle p-type region.
  • the n-type region attached to the positive end of the battery helps slow electrons coming out of the p-type region.
  • the p-type region in the center does both.

Common Emitter Amplier

DC analysis: An emitter resistor is necessary to provide stability of the bias point.  We need to include RE for good biasing (DCsignals) and eliminate it for AC signals.The solution to include an emitter resistance and use a "bypass" capacitor to short it out for AC signals as is shown.

AC analysis of bjt

To start the analysis, we kill all DC sources, combine R1 and R2 into RB and replace the BJT with its small signal model. We see that emitter is now common between input and output AC signals (thus, common emitter ampli er. Analysis of this circuit is straightforward. Examination of the circuit shows that:

Modes of Operation of bjt

Active region of bjt:      

·         Most important mode of operation
                  ·         Central to amplifier operation
                    ·         The region where current curves are practically flat

         Saturation region of bjt:


  •   Barrier potential of the junctions cancel each other out causing a virtualshort

         Cutoff region of bjt :

Current reduced to zero
Ideal transistor behaves like an open switch

ANALOG SIGNALS AND LINEAR AMPLIFIERS

ANALOG SIGNALS AND LINEAR AMPLIFIERS IN ELECTRONICS

Innovative Engineering Projects 

HOW ANALOG SIGNALS USE THE WORKING PRINCIPLE 

we will be considering signals, analog circuits, and amplifiers. Asignal contains some type of information.
For example, sound waves produced by a speaking human contain the information the person is conveying to another person.
ANALOG SIGNALS AND LINEAR AMPLIFIERS

Our physical senses, such as hearing, vision, and touch, are naturally analog. Analog
signals can represent parameters such as temperature, pressure, and wind velocity.
Here, we are interested in electrical signals, such as the output signal from a compact
disc, a signal from a microphone, or a signal from a heart rate monitor. The electrical
signals are in the form of time-varying currents and voltages.

The magnitude of an analog signal can take on any value within limits and may vary continuously with time. Electronic circuits that process analog signals are called analog circuits. One example of an analog circuit is a linear amplifier. A linear amplifier magnifies an input signal and produces an output signal whose magnitude is larger and directly proportional to the input signal.

In many modern day systems, signals are processed, transmitted, or received in digital form. In order to produce an analog signal, these digital signals need to be processed through a digital-to-analog (D/A) converter. D/A and A/D (analog-to digital) converters are considered . In this chapter, we will assume that
we already have an analog signal that needs to be amplified.Time-varying signals from a particular source very often need to be amplified before the signal is capable of being “useful.” For example, Figure 6.1 shows a signal source that is the output of a compact disc system. We assume the signal source is the output of the D/A converter and this signal consists of a small time-varying voltage and current, which means the signal power is relatively small.
Innovative Engineering Projects

The power required to drive the speakers is larger than the output signal from the compact disc, so the compact disc signal must be amplified before it is capable of driving the speakers in order that sound can be heard. Other examples of signals that must be amplified before they are capable of driving loads include the output of a microphone, voice signals received on earth from an orbiting manned shuttle, video signals from
an orbiting weather satellite, and the output of an EKG.

Also shown in Figure 6.1 is a dc voltage source connected to the amplifier. The amplifier contains transistors that must be biased in the forward-active region so that the transistors can act as amplifying devices.

New Electronic Inventions | How They Are Applicable In Electronics

New Electronic Inventions
Inventors, Jung Won Seo, Jae-Woo Park, Keong Su Lim, Ji-Hwan Yang and Sang Jung Kang, who are scientists at the Korean Advanced Institute of Science and Technology, have created the world's first transparent computer chip.The chip, known as (TRRAM) or transparent resistive random access memory, is similar to existing chips known as (CMOS) or metal-oxide semiconductor memory, which we use in new electronics.The difference is that TRRAM is completely clear and transparent. What is the benefit of having transparency?"It is a new milestone of transparent electronic systems," says Jung Won Seo. "By integrating TRRAM with other transparent electronic components, we can create a total see-through embedded electronic systems."The technology could enable the windows or mirrors in your home to be used as computer monitors and television screens.This technology is expected to be available within 3 to 4 years.Source: 

WaterBean Purifies Tap Water, Saves Bottles

Jul-31-13
Designed to help reduce plastic bottle waste, the WaterBean will purify tap water—encouraging water worriers to reuse the same plastic bottle for a longer time.

The WaterBean contracts and expands to fit inside almost any water bottle, and its exchangeable filters remain active for up to three months (or 140 liters of water). The filters are made from non-toxic, activated coconut carbon, which the developers claim will remove chlorine odors and off tastes while also adding magnesium to the water. To use, simply drop the device inside the water bottle, then shake and swirl.

While the WaterBean will not purify dirty water, it will help to improve the taste and odor of tap water, with one filter potentially saving 280 plastic bottles from landfills. The developers are currently seeking funding for their project on Indiegogo.
Smartbox Technology
Insurance companies are implementing smartbox technology so good drivers can benefit from cheap insurance rates.The smartbox, similar to a black box for airplanes, records details about how your car is driven, which can result in cheap car insurance for responsible drivers.The device is connected to the electronics in your car and collects a wide criteria of information such as time, speed, braking, cornering, acceleration and location.The smartbox data is wireless transferred in real time to the insurance company and provides a profile of when, where and how you drive. This profile is then used to compare insurance rates and to reward low-risk driving behavior with cheap insurance rates.Drivers are high-risk when they drive irresponsibly such as speeding, frequent lane changing, driving in high-risk locations or at high-risk times such as in heavy traffic or late at night.These new electronic inventions are intended to replace the standard practice of categorizing drivers into group behavior to determine insurance coverage and premium payments.For example, young drivers are more likely to drive fast, drive at night. and use a cell phone while driving. Statistically, young drivers are more likely to cause an accident so insurance companies charge them higher rates to cover the costs of accident claims.SEE RELATED ARTICLE ABOUT SMARTBOX INSURANCESo even if you're a young, responsible driver, you will pay high insurance rates because of group behavior.This technology allows you to provide proof that your driving behavior doesn't fit the pattern of your demographic group.All the information collected about your driving can be viewed online - including what you're doing well and what could be improved. Your insurance premium is then calculated according to your driving profile.Sources: 
Electronic Pills - Collecting Data Inside The Body
After years of investment and development, wireless devices contained in swallowable capsules are now reaching the market.Companies such as SmartPill based in Buffalo, New York and Israel-based Given Imaging (PillCam) market capsules the size of vitamin tablets.These pills contain sensors or tiny cameras that collect information as they travel through the gastrointestinal tract before being excreted from the body a day or two later.These new electronic inventions transmit information such as acidity, pressure and temperature levels or images of the esophagus and intestine to your doctor's computer for analysis.Doctors often use invasive methods such as catheters, endoscopic instruments or radioisotopes for collecting information about the digestive tract. So device companies have been developing easier, less intrusive ways, to gather information.Digestive diseases and disorders can include symptoms such as acid reflux, bloating, heartburn, abdominal pain, constipation, difficulty swallowing or loss of appetite."One of the main challenges is determining just what is happening in the stomach and intestines." says Dr. Anish A. Sheth, Director of the Gastrointestinal Motility Program at Yale-New Haven Hospital.Doctors can inspect the colon and peer into the stomach using endoscopic instruments. But some areas cannot be easily viewed, and finding out how muscles are working can be difficult.Electronic pills are being used to measure muscle contraction, ease of passage and other factors to reveal information unavailable in the past.Sources: 
Digital Pen
A digital pen is one of the new electronic inventions that can help us record information.Despite the digital age, we still use pens. But it would be great to have our handwritten notes and drawings digitally recorded without having to use a scanner.The Zpen from Dane-Elec is a wireless pen that uses a clip-on receiver to digitally record what you write.It uploads the information to your computer where it can be viewed, edited and filed as a word processing document.The digital pen utilizes character recognition software and works by recording movement. Features include profile creation, a dictionary and fifteen language options.Source: 
Instant Prints
Creating instant prints from a digital camera is one of the new electronic inventions in printing. The Polaroid PoGo™ is a small portable printer that weighs only a few ounces.The printer produces full color 2" x 3" prints using an "inkless" technology. The images are created from heat activated crystals in the photo paper. The photos are water proof, tear proof and smear proof.This new electronic invention connects to a digital camera using a USB cable, or to a mobile phone through wireless Bluetooth. It uses rechargeable batteries or an AC adapter.- See more at:
