Brain Machine Interface Seminar Topic

Introduction to brain machine interface:

In this paper, we will see how the brain machine interface is made and how the capabilities of the human being can be extended. We will about the advantages of using brain machine interface and the problems faced by this.

The capabilities of a human being are limited and a capability of a machine is higher but it cannot think of its own. Research is going on for making a machine to interface with the brain by which the capabilities of a human being are far extended.

Brief on brain machine interface:

The human brain takes decisions based on the impulses generated in the body and in a human body we find millions of neurons which generate impulses. So a chip is designed and it is placed in the human body and it is made to integrate with the nerve fibers. The chip is interfaced with a remote computer outside.

The chip senses the impulses generated in the body and performs the tasks with the help of the remote computer or the server located outside. The chip is designed by using nano technology and it is constructed in such a way that it can generate the power required for it through heat generated in the body or by the flow of blood circulation.

The chip has successfully placed a body of professor in a university and he could control the appliances without lifting his hand from a given range.

Proposed Brain Systems in Future:

The proposed brain machine interface chip can be very helpful to make the organisms to work properly for the paralyzed patients. By using brain machine interface the human capabilities gets increased a lot and many technological advancements can be made.

But due to this there may differentiation in between the persons who are using the interface chips and the normal human being. All details about this system explained in the given ppt presentation.

Similar like that of humans  brain, computers also sometime face the problems of understanding a particular situation and adapting to a new one. The behavior of the machine improved only due to the artificial intelligence. The improved behavior helps in tackling the complex jobs that are based on the deliberate reasoning of high level, abstract thoughts and recognition of patterns. The artificial intelligence can help in understanding the process by recreating it. It helps to enhance it beyond the capabilities of the present situations.

Ambiguity  makes it difficult to understand the meaning that is intended for certain sentences and phrases. It also makes difficult to understand the inferences. Symbolic logic is an unambiguous knowledge representation that is developed originally in order to formalize the attempt for reasoning of mathematics.

Artificial Intelligence Seminar report.

The limitation of semantic networks is the structure that is added which also makes it necessary for distinguishing. The object properties and relationships of the statement are the two distinguished features of the frames. A frame comes with structures in addition and it is simply a node that facilitates the relationships between the object properties and the objects itself. It is known as a representation of “slot-and-filler”.

Reasoning for monotonic:

With time the facts also change

A gather of facts never reduces

The system of monotonic reasoning is very effective for solving problems in various situations.

Principles of NMRs

Y is concluded if the x is unknown.

Again y is concluded if x is not proven

Default reasoning is essential in the presence of incomplete details.

Wireless Networks Seminar

Introduction to wireless networks:

For any communication network it requires a medium for transmission of the signals. Previously wired networks are used in which cables are used for transmission of the signals and due to advancements in technology wireless networks are introduced in which the information signals are transmitted using free space. In this Wireless Networks Seminar paper we will see about various wireless communication networks and devices and their working model and their frequency ranges.

Wireless Networks Seminar

Brief on wireless networks and devices:

The radio communication signals are invented in the 1880’s and later the wireless revolution came in the 19th century and any advancements have taken and now we are using microwaves and laser light for carrying the information.

In the first generation networks the bandwidth capabilities are very less and they are used only for making voice calls, later second networks are introduced which has increased bandwidth and it has added features like browsing capabilities and short message services but it did not have high data rates.

Now the transformation has taken to third generation networks which have enhanced bandwidth capabilities and high data rates. Foe limited usage of wireless networks zigbee protocols are used which is used in short distances and it is used in wireless local area networks.

Conclusions:

Thus we can say that wireless networks allow transmitting signals without the usage of cables. We can transmit signals in very short ranges by using Bluetooth devices and zigbee protocols.

Wireless networks require less maintenance and the faults can be easily identified as they contain only transmitting and receiving systems. Wireless communications are used in space satellites and in mobile networks and the disturbances occurring in these are very less.

The other characteristic which is focused more is the personalized services to the user depending on the user requirement which includes the flexibility also the mobility feature.

When we consider VLSI design styles, several design styles can be considered for chip implementation of specified algorithms. Each design style has its own advantages as well as disadvantages and thus an appropriate choice has to be made by designers in order to provide the functionality at low cost. It includes Field Programmable Gate Array an array of logic cells connected via routing channels. These cells include Special I/O cells and logic cells. When we consider that other design style which comes after FPGA is Gate Array, which is capable of processing fast. The implementation includes with the metal mask design and also processing.

The GA chip utilization factor is higher when compared to that of FPGA and in terms of speed also it is higher. One of the most custom design styles is Semi-Custom design style. All the used logic cells are developed and characterized and stored in cell library. When we consider the full custom design, the mask design implemented without the usage of the library.
