In this communication a compact printed CPW-fed dual band-notched Ultra Wideband (UWB) Multiple Input Multiple Output (MIMO) antenna is exhibited. The UWB MIMO antenna consists of two planar identical monopole elements PPM1 and PPM2 respectively and a novel modified 2nd order Hilbert fractal shaped neutralization line (NL) is introduced along with a modified circular defect in the common ground plane. Modified Minkowski boundary fractal geometry is introduced on the top edges of the respective monopoles for reinforcing the isolation of the MIMO system. The fractal shaped neutralization line serves two purposes isolation improvement as well as band notching the Wi-Max band. Notch bands encompassing 3.3-3.8 GHz Wi-MAX and 3.7-4.2 GHz C-Band are acquired by the introduction of the Hilbert fractal neutralization line and etching rectangular slots on the ground structures. The antennas Ultra wide bandwidth ranges from 3.05 GHz to 13.5 GHz (VSWR ≤ 2). The radiator and ground plane of the antenna are realized with an overall size of 26.75 mm × 32.94 mm. It can be also observed that the spacing between the elements is astonishingly reduced to 0.52 mm which is least as per the knowledge of the authors in UWB MIMO antenna designs proposed in the existing literature. The agreement between the various simulation results advocates that the intended antenna can be a worthy candidate for various UWB communication systems. All the simulated results depict that the proposed UWB MIMO antenna is a promising candidate for portable UWB as well as UWB MIMO systems.

Today's world is facing great challenge of saving their future in terms of energy in next generation. In India, there are abundances of remote villages that are located far away from the grid. These areas normally lack electricity supply because either it is very impracticable to extend the utility grid or it is not feasible economically. As a result, such areas are normally powered by diesel generator to maintain for the demand of electricity. It increases environmental pollution. Further, an increase global fuel prices will have great impact to this community. The renewable energy application has become an important alternative as power provider in rural electrification and for standalone power application. Renewable energy sources have the major advantages for low carbon emission in comparison with conventional energy sources which is rapidly decreasing. But one of the major challenges in harvesting renewable energy sources is the intermittent nature of available energy sources like wind, solar etc. In this paper, we have considered several test conditions for techno economic feasibility analysis of hybrid energy systems. The powerful HOMER software is used for the present study.

Development of computer networking generates many benefits in cyber world. Due to this great advancement, nowadays networking facilities are available at very low cost. But unfortunately this easy access becomes a threat to information security. Watermarking is a technique that is very often used in image processing to trace copyrighted products. It can also be used to trace products which are illegally distributed without permission. In our research work, a new technique for invisible watermarking of images using alpha blending has been proposed. Alpha blending is used to display an alpha bitmap and an alpha bitmap is that one which has transparent and semi-transparent pixels. We have worked on color image and gray scale image. Gray scale image is used as watermark image which is kept hidden in the main scale image by different values of alpha in alpha blending method. This technique is actually done on each plane of the color image. The resulting image contains the information of color image and gray scale images but the main image is unseen to others. PSNR values are also calculated to check the robustness of the reconstructed image. Applying some post-processing work, this can be used in image steganography also.

Human activity recognition plays a significant role in human-to-human interaction and interpersonal relations. Because it provides information about the identity of a person, their personality, and psychological state, it is difficult to extract. The human ability to recognize another person's activities is one of the main subjects of study of the scientific areas of computer vision and machine learning. As a result of this research, many applications, including video surveillance systems, human-computer interaction, and robotics for human behavior characterization, require a multiple activity recognition system. In image and video analysis, human activity recognition is an important research direction. In the past, a large number of papers have been published on human activity recognition in video and image sequences. In this paper, we provide a comprehensive survey of the recent development of the techniques, including methods, systems, and quantitative evaluation of the performance of human activity recognition. The experimental results show that our method can significantly improve classification, interpretation, and retrieval performance for the video images. The novelty of this paper is twofold. First, to capture the video images of human. Secondly, to identify the different types of action performed by human.

We all know that we are slowly moving towards automation which is one of the trending topics. So basically in this project we will be controlling the devices of a room according to the needs. Devices such as fan and lights will get turned on as soon as somebody enters the room and if the room is empty then it will get turned off. Above that, the speed of fan will be controlled according to the temperature of the surroundings. The system will get the temperature from the temperature sensor and it will control the speed according to the temperature, set by the user. In this project, microcontroller forms the processing part, which firstly senses the temperature and the controller then compares the data with the set temperature. If the current temperature is greater than the set temperature the controller turns ON the fan and the set speed will be proportional to the difference between the set temperature & the current temperature. If the current temperature is less than the set temperature, the fan will be turned OFF. The fan speed will change according to the temperature. There will also be a proximity sensor to check if someone is near the fan and if they are, then the fan will stay ON. Otherwise it won't. The doors of a room can be equipped with a laser obstruction detector so as to know if somebody has entered the room. As soon as somebody enters the room the devices such as fan and lights will turn ON and when the room is empty the devices will get turned off. So the energy gets saved by a huge amount. This project will be most helpful for the developing countries where saving energy is one of the most important things. As, their population faces a major part of the day fighting power cuts.

Synthesis of antenna arrays with flat-top patterns is performed using conventional and random drift particle swarm optimization techniques. Optimization objectives are minimization of pattern errors in the specified beam width between first nulls, minimization of ripples within the main beam and maximum side lobe level outside the main beam. Two case studies have been performed, one without any restriction on the range of excitation current amplitude and phase, the other with restricted current amplitude and phase variation. In the first case, random drift particle swarm optimization showed a faster convergence to the optimal solution. Maximum side lobe level corresponding to antenna array parameters obtained from random drift particle swarm optimization is -38.78 dB. In the second case, conventional particle swam optimization performed better compared to the other optimization algorithm. The pattern for array parameters obtained with the conventional algorithm has a maximum side lobe level of -19 dB.

As down-scaling of transistors and up-scaling of technology creating an overwhelming inversely proportional scenario in today's VLSI era, three major components taking into account while designing of CMOS memory cells. As the technology shrinks down, the power dissipation widely impacts to SRAM cells. Along with the power consumption, delay and stability of SRAM cell is also becoming a challenging issue day by day. In this paper, a low power designing approach is being introduced taking advantages of combination architectures of Transmission Gate logic and Gated ground sleep logic. The Transmission Gate invokes a leakage free sub-threshold scenario when Gated ground sleep logic provides a swiftly stacking effect which jointly can induce lowering down power consumption in SRAM cell. This new approach can significantly reduce power consumption upto 75% compared to conventional 6T-SRAM cell. All the experimental works are done by tSPICE 16 with 0.25μm technology.
