Autonomous mobile robots are used in several application areas including manufacturing, mining, military, and transportation, search and protect missions, etc. For the navigation system it is necessary to locate the position of the mobile robot in surrounding environment. For avoiding obstacles efficiently and to reach the target under many different shapes of obstacle in environment, a fuzzy logic controller has been designed to improve the movement of mobile robot according to obstacles positions by defining or establishing input variables, output variables, fuzzy logic membership functions, fuzzy logic rule base `If-Then' fuzzy inference system rules and defuzzification method. Then it has to plan a path towards desired goal. The navigation system of a mobile robot has to identify all potential obstacles in order to search for a collision free path. Obstacles avoidance and destination point can be achieved by changing the direction angle of the mobile robot. To make the mobile robot move in its environment, the basic path planning strategies have been used. While the mobile robot is navigating in its workspace environment, it avoids obstacles and look for the target. In this paper the simulation of path planning technique for an autonomous mobile robot is presented. The figure shows simulation of the mobile robot with four obstacles.

Cryptographic algorithm plays an important role to secure the confidential data while transmitting over the cloud. Modern cryptography offers a variety of encryption scheme for protecting the data. A key used for encrypting the plain text is another vital component on which the secrets depend. Advanced Encryption Standard (AES) algorithm is used in this research. This paper focus on developing a new way to generate the key called Chaive Unica (CU) which is used only once and a new way of substitution method called Advanced Substitution Technique (AST) which is more secure to encrypt the message. The plain text is encrypted twice before sending the message into algorithm. A new architecture is proposed in order to encrypt the text in secured way.

Ayurveda, an ancient and popular Indian medication, says that all five elements – earth, fire, water, air and space – are inside the body just as they exist in the outside world. In a harmonious body fire doesn’t burn, water doesn’t flood it, the earth doesn’t become barren, air cannot blow us away but any disharmony in the five elements indicates that the body needs heeling. This applies to all living organisms including micro organisms like bacteria, plants, birds, animals, reptiles and insects. The contribution of the above all is very much necessary to preserve green in the earth.

Main aim of this research is to develop a robust controller for an inverted pendulum system. Performance of classical PID controller is found to be effective in this regard. However, effectiveness of PID controller depends on its three gain values that require proper tuning. Two different tuning methods have been adopted in this study. In the first approach, frequency response-based Zeigler Nichols PID tuning has been considered. In the second approach, a Fuzzy Logic (FL)-based tuning of PID controller gains has been implemented. Moreover, performance of FL-based tuner has been optimized using a binary coded genetic algorithm. It is observed that control performance of FL-based method is substantially better compared to the other method. It may be due to the fact that FL-based method is not taking into account the nonlinearities and plant uncertainties present in the model explicitly. Both the simulation and experimental analysis have been carried out in MatLab Simulink environment.

Grid computing promotes resource sharing, dynamic computational resource allocation, distributed data access from disjoint application domains and allowing various service providers to meet different demands efficiently. With an increase of user demands to the resources, planning the guaranteed Quality of Service (QoS) is a challenging task. The objective of this paper is to propose an agent based grid framework and QoS Time Based Scheduling (QTBS) algorithm for effective task scheduling in the grid computing paradigm. This algorithm is simulated in the GridSim toolkit and the results shows that the proposed work gives better results in makespan, resource utilization rate and load balancing level than algorithms such as QoS guided Weighted Mean Time Min (QWMTM), QoS guided MinMin, Max-Min and Min-Min heuristic algorithms.

In upcoming technologies multiprocessors are used for the efficient performance improvement. The multi processor system on chip is the complex embedded system used in multimedia applications for the resource utilization and simultaneous accessing. The MPSoC is the processor which uses the n number of resources such as peripherals, devices and processing elements for the improvisation of speed and performance which in turn reduces the execution time and energy dissipation. In general we use the offchip memory which has the cache in order to reduce the time of data fetch. In off chip memory access they use the decoupled approach where the partitioning and allocation of tasks to processor are done separately. Scratch Pad Memory is the fast on-chip memory which is the part of integrated chip memory (RAM). The SPM is the on-chip memory which can be used for the integration approach of task scheduling and memory partitioning. The integrated approach uses heuristics algorithm which increases the performance but when data needed is not available it leads to cache conflict. Thus the cache conflict is also been resolved by the use of segmented LRU algorithm. By the use of these two algorithms the execution cycle time is been reduced which can be evaluated using various benchmarks.

The use of renewable energy technology to meet the energy demands has been increasing for the past few years. However, the important drawbacks associated with renewable energy systems are their inability to guarantee reliability and their intermittent nature. At present, standalone solar photovoltaic energy system cannot provide reliable power during night time or non-sunny days. The standalone wind system cannot satisfy constant load demands due to fluctuations in the magnitude of wind speeds from hour to hour throughout the year. This work focuses on the development of a supervisory model predictive control method for the optimal management and operation of hybrid standalone wind-solar energy generation systems. The proposed method is to design the supervisory control system via model predictive control which computes the power references for the wind and solar subsystems. The power references are sent to two local controllers which drive the two subsystems to the requested power references. The system is modeled in MATLAB SIMULINK and simulation results show that maximum power generated from hybrid system at varying environmental conditions.
