A system of architecture is present with us in this paper that allows user interaction with the systems that are embedded. They act within the proximity with the help of smart phones. Four interaction models have been identified by us between the surrounding environments and smart phones. Dual connectivity, gateway connectivity universal remote control and peer-to-peer are the four connections and although each of them are completely different from the other but our framework is unique for all.

The communication of hybrid has been just central to our architecture system and it has the capabilities to incorporate the use of smart phones. Short range wireless connectivity are the special and unique features of this connectivity like Bluetooth and internet connection. All these are possible only in a single handset. Along with high processing power these features can change a smart phone into a simple mobile device that can be easily carried by people. 

In this paper we have discussed about converting the smart into a simple mobile device so that it can easily fit inside a pocket thus making it easy for people to carry it with them wherever they go. Usually Smartphones can be used as personal server as well as a personal assistant. The former one helps in storing and downloading of data as per the needs of the users whereas the later one helps in remote interaction along with the systems that are embedded and located in the near proximity of the user’s.

For achieving this goal we have presented a system architecture for various models. In the central position of the universal integration architecture there is a dual connectivity system of smart phones that allows them to communicate with the close environments with the use of short-range networking of wireless connections. This is one of the best proposed system that will increase the smart phone usage.

The communication is termed as synchronous when a character or byte is received at constant intervals of time with a regular gap in the phases. Data that are formed are sent in a tine internal of a maximum time and this time also varies in time. In certain special cases it is known as ISO-synchronous. Again, asynchronous commission signifies those bytes that are received at various intervals of times. Voice data and telephone line are the examples of asynchronous mode.

Internal devices are available in micro controllers like SCI, SPI and SI. Separate status, registers for controlling purposes are available for each device and so that they can transmit and receive serial and data bits. Moreover, each of the devices is programmable and can be used in IO mode programs as well as in interrupted driven transmission.

The synchronous peripheral interface port has the feature of full duplex for the purpose of synchronous communication. For MOSI, MISO output and SCLK there are signals. In clock bits there is is a programmable rate with SPI feature. It also helps in the programming of positive and negative edges with a bits interval in the serial data in and out. It can also be programmed for the selection of device for slave and master.

The serial interface port is also known as a USART port and programmable rate registers are a one of its most important features. SI works in the mode of half duplex synchronous call mode0 and the full asynchronous mode is termed as mode 1 mode 3 or mode 2.

Serial connect interface port is also a UART asynchronous port mode and communication is made in the full mode of duplex for the transmission and receiver of SCI. The band arts for SCI baud are fixed and the receiver of SCI comes with a wake up character which can be programmable using RWU or Receiver Wake Up Unavailable bits.

The parallel port is easier to interface in comparison to the serial port and in most of the cases any device that you connect to the serial port it will need to undergo serial transmission. Under this transmission system the serial port is converted back to the port of the parallel system and it can make work easier. The UART is the only process to accomplish this. According to the software side there are various users on a standard parallel port that you need to attain.

Do you know the advantages of using the method of serial data transfer instead of parallel one?

Usually parallel cable is shorter than serial cables. The serial port transmits 1 at -3 to -25 volts and 0 at +3 to +25 volts. On the other hand, parallel port transmits 1 as 5v and 0 as 0v. Therefore 50v is the maximum amount of swing that is possible by a serial port and in comparison to the parallel port it is 45 times more. There the problem of cable loss is not much in serial port as they are in parallel port.

As in case of parallel transmission, serial port installation does not require much wires. If also you learn to mount it at a far away distance from the computer then you can use the null modem configuration that is going to cost much less than the original wiring. This configuration usually requires 3 core cable and it is cheaper than using 25 or 19 core cable wires. The cost of interfacing at both the ends must be taken into consideration.

Recently, the use of microcontrollers has proven to be very useful and most of these are built in SCI future. This can be used to communicate with the outside world. On the other hand, serial communication reduces the count of pin of these MPU’s. Two pins are used commonly that includes receive data and transmit data.

In this research project, utilizing fake neural system so that the transmission misfortunes are minimized, the situation of reactive power improvement is illuminated. Contrasting stacking states of reactive power were described as data designs to develop the neural grid to recognize the closest key for a given and untrained reactive-power managing conditions.

Then again, there may be sure system scenario where the grid result was not possible, and certain transport voltages could outdo their reasonable cutoff points. When this scenario happened, a standard-based methodology was utilized to control variables to realize commonsense result. Numerical effects of an actual framework have demonstrated that the recommended way is viable and hearty for taking care of the situation of reactive power enhancement.

Introduction to Shape Memory Alloys Technical Seminar Topic:

An alloy is a homogeneous mixture of two or more metals. Shape memory alloys are metals that never lose their original shape.

The standard feature of shape memory alloy is martensitic phase transformation. Martensitic transformation follows deformation of crystal lattice and diffusion less process. Deformation is alteration of shape by pressure and diffusion is transferring the atoms or molecules by their random motion from one part of the molecules to anther. 

Properties: 

It has the two unique properties those are: i) shape memory effect ii) pseudo-elasticity

In shape memory effect the transformation is done without stress, at particular temperature say M^0f until the temperature is lowered to M^0f then reverses transformation starts at A^0s and at the temperature of A^0f the metal will be formed. Pseudo-elasticity is done under a fixed temperature; transformation is based on loading and unloading. These types of alloys are just like rubbers they contain the elasticity.
