This paper discussed about a challenging task of providing security in Ad-hoc networks and also discussed about attacks, security mechanisms and different aspects of security services.  Attacks in ad-hoc networks are classified into active and passive attacks, depends on whether the networks normal operation is disrupted or not. 

Overview: 

A wireless network can be viewed highly, so requires more sophisticated and efficient security mechanisms. External attacks are occurred by nodes which are not part of the network.  Encryption and firewalls can prevent external attacks.

Internal attacks are occurred by nodes which are part of the network. It is difficult to detect internal attacks and the impact of these attacks is severe when compared to that of external attacks.  Integrity refers the information passed on two different nodes has not been altered during the transmission. An user identity can be determined by a network service, Authenticity. 

The two important mechanisms used for data integrity and authentication are message encryption and digital signatures.  Symmetric and Asymmetric are two popular data encryption mechanisms.  The secret key is used for both encryption and decryption in symmetric mechanism where as public and private keys are used for encryption and decryption respectively in asymmetric mechanism.  

Digital code attached to a message helps to identify the sender uniquely.  The key component of most authentication schemes is digital signatures.  Some of the popular existing security mechanisms are asymmetric cryptography and one way hash functions. 

Conclusions: 

Security threats in ad-hoc networks and security objectives need to be achieved are discussed in this paper.  Ad-hoc networks are highly vulnerable to security attacks and some of applications in this network require high degree of security.  This paper discussed about existing security providing techniques and as well as new mechanisms to secure ad-hoc networks.  Along with preventing security attacks in ad-hoc networks there is also need to identify the impact of security mechanisms on the network performance.

Introduction to Robotics in Surgery Seminar Topic:

This paper discussed about an emerging technology, surgical robotics. Robotic surgery is becoming an important tool in surgical armamentarium.  Most of the researches saying this robotic surgery technology is more feasible. Researchers are still carrying out on this evolving technology and the comparison of this technology with conventional technologies is also taking place rapidly.

Overview:

Robotics has entered into medicine field slowly but got its own importance with short span of time. To perform transcontinental cholecystectomy, robotic telesurgical medicines are already in use. Initially robotics has entered into market as a replacement of conventional laparoscopic procedures. As the usage of this technology is cost effective, only few of surgeons got trained in robotics to make use of this technology in their routine surgeries.

For a several surgical procedures, FDA has already approved few robotic systems. Many studies are carrying out to evaluate the advantages of robot-assisted surgeries. The usage of robotics system in pediatric laparoscopic surgery is still under investigation.

The main disadvantage of these robotics systems is their cost so cannot use this technology highly in routine surgeries. The enhanced vision of these systems is highly remarkable. Unlike the conventional laparoscopic camera views, this system has 3-dimensional view with depth perception.

These systems have the capability to scale movements so that the large movements of the control grips can be converted into micro motions inside the patient. These systems help to make impossible surgeries also into more feasible.

Introduction to Technical Seminar Presentation on Non Linear Second Order Harmonics:

This project is mainly to explain about the linear and non-linear elements. Non linear optical wave guides are made of LiNbO3, LiTaO3 and optical crystal. In case of microwave applications not linear properties of huge-Tc Superconductors are apprehension very morally.  With different crystalline and width it was concluded that a significant part of the second harmonics signal is generated. Succeeding Harmonic production is a not linear process. It generates a photon at frequency 2omega and it creates when the communication occurs between the elements. In a quartz crystal we can observe second harmonic generation.

            Using semiconductors we can generate the succeeding harmonics. Due to presence of electric field can permit SH generation through a third-order process called electric field induced succeeding harmonic production. To remove any non electric field dependent signal dual-modulation technique is used. Moving the sample so that beam focuses on the metalized surface on either side results in no SH generation. Second order non linear harmonics consists of sensitive tools which used to study the surfaces and thin films. Susceptibility tensor is characterized based on the responses. Based on electromagnetic theory susceptibility is expressed.  Measuring signal is taken in case of measurements.

            The materials used in SGH are Cs vapor and trintrosubphthalocyanines.  Organic modules are used because it combines advantage of synthesis edibility for chromospheres design and synthesis together with fast purely electronic response.  This project uses a laser beam to electric fields, which are strong enough for non-linear effects to be observed. Now researchers are attracted in generating optical nonlinear succeeding order harmonics from organics.

Introduction to ECE Technical Seminar Topic on Light Emitting Polymers:

The emission of light is very essential need in the current days. In the year 1990, the inventors introduced a light emitting technology using polymers and it named as Light Emitting Polymer [LEP]. The Light Emitting Polymer is a type of emissive technology which emits the light treating it as a purpose of electrical task or operation. The LEP is discovered for the emission of light with the need of conducting polymers.

            The LEP is made up of a polymer. This polymer is fixed in such a way that it is in between one anode and one cathode. The type of material that used to develop an anode is Indium Tin Oxide [ITO]. To develop a cathode some kind of metals are used. The polymer is placed in between this kind of materials for the emission of light. The LEP exhibits the characteristics of electroluminescent. The polymers which emit the light will works in the function of electric field such as Polyvinyl Chloride. The polymers are broadly classified into three types such as conductors, semiconductors, and insulators.

            The LEP comes into operation when we apply the electric field in between the cathode and the anode. When we apply electric field in between both electrodes, both the positive charge and the negative charge will travel in polymer. The cathode will inject the electrons and the anode will inject the holes. During this operation the charges which are injected will recombine and decomposes. With this combination it will generate one neutral exited state.

After this the ITO surface will be covered with polymer. Then the alcohol based cleaner is used to clean every surface and it is placed near to UV ozone cleaner to bombard with UV rays. After this process spin coating will be done. On the above part of electrodes some samples are placed connect them to high resistance metal alloy. The next step is testing. It consumes less energy and covers long distance. Therefore, LEP is a technology that has the properties of electrical and optical technology and provides flexible lighting.

Introduction to Electrical Seminar Idea on The Prospects of Nanotechnology in Electrical Power Engineering:

The electrical power is such a application through which many technologies are rising with a great success. In these quick rising technologies, one of the successful technologies is nanotechnology. Not only in electrical power engineering but also in all the engineering and medical fields this nanotechnology is playing the major role.

Even though the cost of this technology is high, it is very successful. The nanotechnology is a successful technology because of its much accuracy or its control towards the losses. This project includes the possible applications using nanotechnology in electrical power engineering. The main intention is to increase the lifetime and to decrease the maintenance’s along with size and cost of high voltage insulation systems. To understand the concept of nanotechnology in electrical power engineering, a existing application depending upon nanotechnology is explained in this project i.e., nano-coated porcelain insulators.

          In electrical power engineering, the nanotechnology is used to reduce the losses, improve the insulators, and increase the reliability, and to improve the lifetime along with the efficiency. The knowledge of nanotechnology energizes some researchers to implement one application i.e., reducing the ohmic losses at metallic conductors with the help of Carbon Nano Tubes [CNT]. Using this CNT we can notice that the resistivity of room temperature will be 50% less than Cu. In the electrical industries during production the main drawback is ohmic losses.

To overcome this drawback CNT can be used. The regular problems in ceramic outdoor insulator are like corona discharges and leakage of current. To overcome this problem the developers can use the products which are made up of nano liquids can be used. The nanotechnology is such a technology through which we can overcome a lot of problems and to find the solutions for failures. The nanofillers are also made up of nanotechnology used to modify the thermal conductivity and resistance of insulating materials. As a result, the nanotechnology is very useful in manufacturing the products with much efficiency, lifetime and reliability.

Introduction to Fuzzy Adaptive Filter Technical Paper Presentation:

Fuzzy adaptive filter presents for an inherent closed loop to alter signal excellence for different cable plants and ecological circumstances. Linear techniques be unsuccessful is in image processing where conventional techniques cannot handle with the nonlinearities of the image configuration model and do not take into report the nonlinear nature of the human visual system. The nonlinear image processing is done with the help of the Fuzzy logic, where conventional techniques are unsuccessful.

Adaptive filters are used in different areas where the numerical information of the signals to be filtered and analyzed are not known a priory or the signals may be gradually time alternate. The system tries to decrease the collision of the noise in the primary input exploring the correlation among the two noise signals. This is correspondent to the minimization of the mean-square error E[e2(n)] .Fuzzy logic adaptive controller (FLAC) is used to sense the bias of dimensions and put off deviation of the extensive  filter.

The FLAC necessitates minor amount of states as a result it require a smaller amount computational effort. Fuzzy variable or the associative functions recognize the rating of both input variables. kalman fuzzy adaptive filter method has been functional to combine position signals from the Global Positioning System (GPS) and Inertial Navigation System (INS) for the independent portable vehicles. The presented method has been authorized in 3D surroundings. The noise feature has been tailored by means of the Fuzzy Logic Adaptive System and match up to with the performance of regular EKF.

The relative simplicity and the clear-cut execution of the fuzzy operators, the fuzzy filter is capable to fight with state-of-the-art filter techniques for decreasing the noise. Fuzzy nonlinear filters symbolize a entrenched technology for multi channel image processing. The fuzzy filter scheme is satisfactorily easy to allow quick hardware implementations.

Introduction to Electrical Seminar Topic on Security Alarm Systems:

Providing security to various organizations is one growing challenges in today’s growing world. There are various methods for providing security like video camera monitoring method and object detection by using sensor method. In this paper we will propose a method which consists of transmitter and a receiver which uses ultrasonic signals for detection of objects using ultrasonic signals. In this paper we will see how the circuit is designed and the how the ultrasonic signals detect the objects and based on the detection alarm is given.

Brief on the working model and design:

Here we use ultrasonic signals of same frequency in the receiver and the transmitter and they cover a certain region of an area, when these signals are interference by a object the alarm is blown. Here we use ultrasonic transducers which are used for both input and output operations. To drive these transducers we use a two nand gates which is built around transmitter out of the four gates present in the IC3.

The devices connected to the IC3 form multivibrator which is used for driving the transducers. To make the output frequency to match with the resonance of the transducer we use a trimmer P2 by which we can adjust the frequency accordingly. Here we find the same transducer circuit in the receiver and the received signals are amplified by the transistor of the IC1 op amp.

The output of the IC1 is given to the IC2 and the amplification factor is adjusted by using P1. This acts as a inverting circuit and if the signals detect a object then the frequency changes occur in the signals and these signals are sent to the receiver due to frequency changes the distortion occurs which blows the alarm.

Conclusions:

The proposed method is efficient way for detecting objects interfered by which we can provide security by blowing alarm. We can even use other methods for providing security but this is the effective method and requires low maintenance cost. By using this method the time interval for blowing alarm when the object is detected is very less.
