Technical Seminar Presentation for ECE Students on Light Emitting Polymers with PPT

Introduction to Technical Seminar Presentation on Light Emitting Polymers:

The paper is about light emitting polymers .where LEP is a technology which emits light based on the electrical operation performed. LEP, it exhibits the electro luminescent features. The concept of LEP was started in early 1990’s. The emission of light is due to the electric field application.

The conduction of the polymers includes a conductor, semiconductor and insulator. Conductor is used for conducting the electric current. It allows the flow of electric current through it equally in all directions and the flow of the current depends upon the amount of the resistance of the conductor and also the amount of voltage applied.

The semiconductor allows the flow of electric current in only one direction and weakly in other direction. The flow of current depends partially on amount of voltage but mostly depend on forward and backward resistance. Whereas the insulators do not conduct electricity i.e. they are the very bad conductors of the electricity.

The structure of LEP includes an anode, cathode and a thin film of polymer. Generally metals can be used as cathode and tin oxide can be used as anode, whereas the thin film of polymer is used in between cathode and an anode. The implementation is as follows, initially an electric field is applied between the electrodes and the electrons are then injected from cathode and anode and also the injected charges are combined again.

The advantage of the LEP includes the lowest consumption of the energy, it is an easy to use technology and it supports all the future requirements and provides flexible lighting and also provides large area lighting.

We can conclude that LEP implementation is easy and cost effective. It provides flexible lighting and it is a technology of present and even supports the future.

Technical Paper Presentation on Electrocardiography with PPT

Introduction to Technical Paper Presentation on Electrocardiography:

The paper is about Electrocardiography which is used for measuring the electric activity of the heart .This activity is done by electrodes which are attached to the outer surface of the skin and this activity is recorded by the device placed externally outside the body. An ECG test is used for recording the electric activity of the heart.

ECG’s are used for measuring the regularity of heartbeats. It is also used for verifying the position of the chambers and also indicating of any damage to the heart. Most ECGs are used for performing the research on human hearts. And the implementation can also be done on animals for identifying abnormalities of hearts.

In general more than two electrodes are used for measuring the electric activity and also the combination pairs are responsible for electric activity. The output generated for each pair is called as LEAD.  Normally these electrodes are places on either side of the heart such that any tiny rises can lead to voltage down between electrodes. It is displayed with a line on a paper or can be displayed on screen. The line is used for finding the rhythm of the heart and also any weakness of the heart if any.

The ECG recorder can be of many types based on either single channel recorder or three channel recorder, and vector electro cardiograph and electro cardiograph system in case of stress testing.

We can conclude that electrocardiography is used for measuring the activity of the heart electrically. This implementation is done by electrodes. ECG’s are used for measuring the regularity of heartbeats. It is also used for verifying the position of the chambers and also indicating of any damage to the heart.

Orthogonal Frequency Division Multiplexing Electronics Seminar Report for ECE Students

Introduction to Orthogonal Frequency Division Multiplexing:

The use of movable communication system was increased tremendously like mobiles PDA’S etc. In this communication only low bit data rate voices is delivered to the destination. The radio channel of mobile is characterized by multi channel reception.

The received signal by receiver is not only LOS(line of sight) radio waves besides a lot of reflected radio waves can be received at different time intervals. The delay in signals is due to reflection of waves from hills, terrains, buildings etc.The waves which are reflected will cause interference that means they reflect each other which causes significant degradation of network performance. The wireless system such as mobiles and Tabs should be minimized from these effects. All these effects are overcome by orthogonal frequency division multiplexing system.

Working of OFDM:

  • The transmitter converts the input data from serial stream to parallel sets. It contains symbol Xk for each carrier. A set of 4 data will be 1 1 1 1 -1 -1.
  • If the transmission takes 4 seconds then than each piece of data has 1 second duration. OFDM sends the data one after another if the duration of the data is 4 seconds.
  • If the communication length is high the transfer speed and quality become shorter. The delay caused in the multi path remains constant.
  • OFDM is highly suitable for high speed communication because of IST restrictions. Because it avoids low speed data transmissions.
  • OFDM channel has 128 to 2048 sub-carriers and can occupy bandwidth from 1.25 MHz to 20MHz.
Channel bandwidth 1.25MHz   2.5 MHz   5MHz       10MHz   20Mhz

DMA Controller ECE Project Report

Introduction to DMA Controller ECE Project:

DMA controller is a device which controls the system to directly transfer the information from one peripheral to another. The controlling is necessary because the data move very fastly even faster than a particle. For example take a black and with picture with 256 and 240 vertical and horizontal dots respectively then  the picture is scanned twice that means 60 times every second when this dots are represented double on display. 256×240=61400 bits of information scanning of these bits twice means two microseconds for every bit.

For this process of fetching every time the memory and time also wasted. To avoid all this problems the data should be stored on onboard memory with built in scanning technique. This can be achieved by maintaining a ram and vram. The frame buffer refreshes every time when the data is accessed. DMA takes control over system bus and produces its own address and control’s information of system bus. Due to narrow timing constraints it is not suitable for scanning video for regular display. DMA is used regularly when the picture is transferred from regular memory frame buffer. It gains control over the processor which are using bus.  Intel 82357 DMA controller is used to control the transfer services. It has 40-pins. By maintaining several DMA chips together any number channels can be supported.

DMA Data Transfer:

DMA transfer can be triggered in two ways they are

  • By Software
  • By Hardware

Software:

                   When the process is executing DMA buffer is allocated and hardware is instructed to transfer the data in buffer the hardware writes the data and raises an interrupt and it is received by interrupt handler and it is handled.

Hardware:

                   The hardware notifies a new data is received. The interrupt handler asks the hardware where to transfer the data. The device writes the data and notifies once again.

Laser Assisted Machining Of INCONEL 718 ECE Seminar Report

In this paper we introducing a new innovative technology in machining brittle ceramic materials with the help of lasers, Laser Assisted Machining (LAM) is a way of machining hard-to-wear materials, which cannot be performed using ordinary conventional methods, LAM employs laser technology with general machining methods such as turning and milling.

In this process first we smoothens the surface of the given ceramic material using laser and gradually we cut the parts that are used for machining, heating the interior will not damage the interior of the machine, these lasers are employed under very high temperatures about 1000degers centigrade and above, by using lasers minute operations can also performed at the interior parts of the machine.

In recent years laser assisted machining had improved a lot in terms of research and development, Nd:YAG laser is used for these experiments, and presently we use the work piece  Inconel 718 for our project.  These experiments had revealed that the capital cost in laser assisted machining had decreased up to 60%, it significantly minimized the cutting force upto40%, This Inconel alloy 718 has several advantages like high tensile strength, minimum corrosion and it is alloy of nickel chromium metal.

The balancing condition between corrosion and oxidation is maintained within limits. The main objective and considerations while introducing this Laser Assisted Machining is provide minimum surface hardening, less interior defects, to reduce the tools and running cost, reaching the target with in very less time with maximum material removal rate, and to attain high reliability with maximum accuracy, the smoothness is increased due to lower dynamic cutting force.

Future scope:

The methodology has to be improved in the areas of in maintaining proper rotation speed and distance between cutting piece and tool kit has to be modified, work should be done on improving the laser power, these are challenges facing up to now, upcoming researches will overcome these remedies.

Optical Communication System without Fibers ECE Seminar Report

Introduction to Optical Communication System without Fibers Seminar Topic:

Now-a-days everything every work we want to have is faster things. If it works fast means it will be the most popular thing. In day today life speed is the main concern. One of the main field which require high speed is communication. Communication has been always simply relied on speed.

In long ago, olden days communication had been continued through fiber cables but now in this twenty first century wireless network is spreading everywhere rapidly because of its speed and relatively high robust network. For a wire line network physical damages may occur frequently but for wireless system there will be no such kind of damages.

By the invention of laser beam in 1958, optical communication has been originated and developed low loss fabricated optical fiber in 1970. By saying optical communication means we think of optical fibers but in this project of optical communication system without fibers we are going to deal optical communication without using fiber can also call free space optics (FSO).

Free space optics is not a new concept, it is developed before the fiber optic cable became the transport medium preferred for high speed communication. This free space optics or FSO technology offers high bandwidth last mile connectivity to the requirement of today’s converged network. This Free space optics (FSO) technology was used in defense and aerospace applications.

FSO technology can transmit up to 2.5 gbps of data, video and voice communication and it is a line of sight technology. FSO communicates at the speed of light as wireless communication means transmission of a modulated infrared or visible beam through atmosphere.

As the speed of light is faster in air medium than glass, with FSO also we can communicate at light speed as we use LEDs or LASER beam for the transmission. This project gives detailed description about free space optics technology.

Polytechninic Seminar Topic on Designing Network Monitoring System Communication with Report

Introduction to Polytechninic Seminar Topic on Designing Network Monitoring System Communication:

The communication between computers for file sharing and accessing data on other computers is called network. Network is defined as communication between collections of computers for sharing resources for example Printer.

The network is classified into three types based data speed and band width and transfer and receive capabilities.

They are:

  • Local Area Network (LAN)
  • Metropolitan Area Network (MAN)
  • Wide Area Network (WAN) 

Local Area Network (LAN):

          LAN is a network between only a number of computers that they are existed with in the building. The speed is up to 512KBPS speed. The band width is small compared to MAN. 

Metropolitan Area Network (MAN):

     MAN   network that connects over the city or town and its coverage distance 10-100KMS. The Band Width is high compared to LAN as well as Speed also. Its speed is around 100MBPS.

Wide Area Network (WAN):

 WAN covers the countries its range of coverage is 10,000 kilometers. Its band width is very high and speed is also in GBS Up to 10GBPS.

These networks are allowed to interconnect with different media like twisted pair copper wire, optical capable, coaxial cable, Bluetooth (it covers a meter of distance).In September 1940 George stibitz used to transfer the results from his college to New York and the calculator received the results.

The Network monitoring Includes:

• Automatic Discovery

• Smart Classification & Mapping

• Indepth Performance Monitoring

• Security Management

• Intelligent Alerting

• Solution’s Scalability 

Conclusion:

By this network monitoring system one can easily accessed from home and can be monitored. Security is also provided for this system without accessing of intruders and hackers.
