Starting from this statement we designed a circuit that has four circuit elements: a linear passive inductor, a linear passive capacitor, a nonlinear resistor and a thermistor, that is, a nonlinear "locally active" memristor. Thus, the purpose of this work was to use a physical memristor, the thermistor, in a Muthuswamy-Chua chaotic system (circuit) instead of memristor emulators. Such circuit has been modeled by a new three-dimensional autonomous dynamical system exhibiting very particular properties such as the transition from torus breakdown to chaos. Then, mathematical analysis and detailed numerical investigations have enabled to establish that such a transition corresponds to the so-called route to Shilnikov spiral chaos but gives rise to a "double spiral attractor". Michael Faraday (1791-1867) is generally well known for his contributions to the study of electromagnetism and electrochemistry. However, according to Orton 1 , while investigating the effect of temperature on the conductivity of "sulphuret of silver" (silver sulfide) in 1833 he discovered what is now considered as a thermistor 2. Thermistor, i.e., thermal resistor, is thus an electrical-resistance element made of a semiconducting material the resistance of which varies with temperature. Thermistor production was then difficult, and applications were limited. One century had to pass before thermistors became commonly used by commercial manufacturers. In the 1930s, Samuel Ruben (1900-1988) invented the first commercial thermistor that he called "electrical pyrometer resistance" (Patents N o 2,021,491). He explained that: This invention relates to an electrical pyrometer and specifically to one utilizing the resistance change of a metallic compound with heat to indicate temperature changes. The characteristic property of the material employed for the temperature indicating resistance element is one having a high negative resistance coefficient.

The production of aquaculture mainly depends on the quality of land selected for aqua farming. Neural Network algorithms have been applied to classify the aquaculture sites based on 6 input variables viz., water, soil, support, infrastructure, input and risk factor. An artificial neural network (ANN) consists of huge number of interconnected elements called neurons that work together to solve a specific problem. An Artificial Neural network can be used for classification, prediction, pattern recognition etc., through a learning process. In this paper, the models were constructed using three Neural Network algorithms viz., Back Propagation Network (BPN), Radial Basis Function (RBF) and Linear Vector Quantization (LVQ). The models classify each aquaculture site into 3 classes viz., suitable, moderate and unsuitable. From the results of the three models, it has been found that Radial Basis Function model not only gives accurate results but also time taken for training the dataset is less when compared with the other two Neural Network models. The results obtained from the neural network models were validated with the results of the fuzzy model.

This research provides a hardware and software platform to address this issue. Two types of research have been conducted in this paper. First, a hardware platform consisting of a Linear Actuator-based steering mechanism is implemented to hold the steering at the desired angle. Second, the curvature information from Google Maps path data is collected and used to improve the existing Pure Pursuit algorithm, which is known as the curve-aware Pure Pursuit (C-PP) algorithm, which navigates a mobile robot in both on-road and off-road (with scattered small obstacles) environments. The mobile robot is navigated using C-PP and steering is controlled by a Linear Actuator. The results taken in real-time and simulation show that the proposed algorithm for on-road and off-road environments has lower longitudinal and lateral RMSE values compared to the existing algorithms. INDEX TERMS Mobile robot, curvature path, pure pursuit, linear actuator.

Baptista [2] has demonstrated how to use the chaotic solutions of Logistic equation for encryption. In order to increase the efficiency, we extended the method for a two coupled logistic equation . In this method, we divide the available phase space of a two coupled logistic equation into 94X94 boxes, each of which are associated with a pair of alphabets. A sender divides his messages into pairs of alphabets and identifies the associated box in the phase space. For this purpose, the two coupled logistic equation is iterated until the chaotic trajectory reaches the identified box. The corresponding iteration number is converted into its equivalent binary. The binary data is embedded into an image using standard steganographic technique and it is transmitted to the receiver. The receiver does the reverse operation for identifying the text. The similar process is repeated for all pairs of alphabets.

The existing chaining schemes are not reliable because there are frequent breaks in the chain among the clients due to stringent bandwidth and buffer, stop fail, and hardware and software failures.

The objective of the paper is to maximize the availability of streams for the peers in the VoD system. We have achieved this by using data replication technique in the peers. Hence, we proposed a new data replication technique to optimally store the videos in the peers. The new data replication technique generates more number of replicas than the existing techniques such as random, minimum request and maximize hit. We have also investigated by applying the CTMC model for the reliability of replications during the peer failures. Our result shows that the mean lifetime of replicas are more under various circumstances. We have addressed the practical issues of efficient utilization of overall bandwidth and buffer in the VoD system. We achieved greater success playback probability of videos than the existing techniques.

They are finding applications in motor drives, active filters and power conditioning. Cascaded Multilevel inverter is the most used topology among Multilevel Inverters, due to reduced number of components at higher voltage levels. Constant frequency PWM is normally employed for cascaded multilevel inverter. However, to overcome EMI and higher harmonic distortion, a random modulation technique, adopting pseudorandom carrier modulation is employed. This improves the spread spectra effect; where in the signal generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with wider bandwidth. The pseudorandom carrier involves random selection of two triangular carriers of same frequency but opposite in phase depending on the output states of pseudorandom generator. Pseudorandom carrier modulation is employed on various kinds of sub harmonic PWM techniques. Total Harmonic Distortion (THD) and Harmonic Spread Factor (HSF) are considered for evaluating the performance of these methods .HSF was found to be 5% less in pseudorandom carrier scheme compared to constant frequency scheme. Current THD was found to be less than 4% in all schemes.
