Though photovoltaics (PVs) are considered to lead the renewable energy sector, they have a shortcoming of not providing constant level power supply and this where this paper fits in to propose a possible solution. Gaussian-shaped outputs from solar panels are due to the way the available sun light is captured; and this directly depends on the positioning of solar panels. Techniques that have been applied, automated sun-tracking panels, have not been to the level of producing regulated outputs though acknowledgeable for improving output levels. This paper describes and develops a model that consists of making use of prism-shaped PV systems in order to ensure there is a same amount of PV area that faces the during the daytime. Also known as closed-structure- multisided (CSM) approach, it could sound obvious, yet the power dynamics and the accurate figures to quantitatively be determined and all this was deeply elaborated herein. As for the results, a cylindrical-shaped CSM PV system was qualified to provide the same level regulated power average as the average value of a single fixed-tilt PV panel of the same area and material.

This paper introduces analysis of landslide detection based on wireless sensor network and GSM. And also here we introduce some other methods used for detection of landslide. We are also trying to give short information about our proposed method which is implanting next paper. This paper presents an independent landslide monitoring system based on wireless sensor networks and GSM. Provides real time measurement of various constraints such as amount of rainfall, moisture, and movement of land when trees and rocks are about to fell and also drive of the land as landslide occurs due to the earthquake are read by the microcontroller. The planet Earth has hundreds of impact events, with some occurrences causing both in terms of human casualty as well as economic losses. Such attitudes of earth pushed the frontiers to develop innovative monitoring strategies for the earth system. To make that real, although, will require coherent and real-time data by observing the earth behavior contiguously. Here sensors are very powerful device which used for real time monitoring. For removing such type occurrences we choose the sensor network and GSM. The sensor is a major device in electronics for measuring physical data from the environment. In the direction of the landslide prediction, sensor can play a great role, where sensor connected with wireless protocol can make it very useful for remote areas landslide mapping, detection, analysis and prediction etc. A wireless sensor network consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, including temperature, sound, pressure, etc. is found be worthwhile.

The wireless LANs have been deployed at many places, small or big, houses or commercial complexes mainly because of their ease of installation and use. The IEEE 802.11-based WLAN presents new challenges for network and information security administrators. Whereas the security requirements of wired Ethernet deployments are relatively simple, security of a WLAN is somewhat complex. 802.11-based WLANs broadcast radio-frequency data for the client stations to receive. Hence, there are complex security issues that involve augmenting the 802.11 standard. This work critically reviews main security flaws of Wired Equivalent Privacy and suggests a new approach of automatic key management and refresh of WEP key so that attacker could not get sufficient time to guess the key.

This paper gives an insight to labview software tools which helps in analysis of ECG signals. The raw ECG data are taken from MIT-BIH Arrhythmia database. In the first stage ECG signal is acquired which is then followed by filtering the raw ECG signal to remove unwanted noises. The next stage focuses on extracting the features from the acquired signal. Finally different types of abnormalities are detected on the basis of features obtained. Thus the developed system predicts the heart abnormalities of a person, even before him/her consulting a doctor (preliminary investigation). The technique is user-friendly, low cost and hence anyone skeptic of heart problem can analyse his/her ECG using this efficient method.

Video compression has become one of the basic technologies of the multimedia age. In many applications, such as the design of multimedia workstations and high quality transmission and storage, the goal is to achieve transparent coding of Image and video at the lowest possible data rates. In other words, bandwidth cost money, therefore, the transmission and storage of information becomes costly. However, if we can use less data, both transmission and storage become cheaper. In this paper two techniques are used together to achieve high compression rate. In video frames, seam curving technique is used as Intra frame coding and DWT is used as Inter frame coding. Both Inter-Intra frame coding are used to achieve desired result.

In this paper, we present an improved path planning method and obstacle avoidance algorithm for a 2-wheel mobile robot. Firstly, we briefly introduce the rapidly exploring random tree (RRT) and the single polar polynomial (SPP) algorithm. Secondly, we present additional 2 methods for applying our proposed method. Thirdly, we propose a global path planning, smoothing and obstacle avoidance method that combine RRT and SPP algorithm. Finally, we present simulation using proposed method and check the feasibility. This shows that proposed method is better than existing methods in terms of the optimality of the trajectory and the satisfaction of the kinematic constraints.

Quantum dot cellular automata (QCA) is a computing approach, in which binary information is represented as the charge configuration among the quantum dots. In nanoscale integrated circuit energy consumption and area utilization are a major concern, hence in recent years QCA has attracted a lot of attention as a result of its extremely small feature size and low power consumption. This technology is best suited for the semiconductor fabrication because of its less time consuming and less expensive methods. As per Moore’s law, number of transistors in an integrated circuit doubles for every two years, fabrication process faces some technical barriers. In context of this, QCA has emerged as the most promising technology, as an alternative to CMOS technology. In this paper efforts have been made to show the work carried out on QCA and focused on the science and technology applications of QCA due to its many interesting and important applications such as parity generator and checker.

In this paper theoretical design and optimization of VSWR BW of a waveguide based Inter-digital filter using PSO-ANN algorithm is highlighted. The objective of this paper is to focus on use of the trained ANN model coupled with the particle swarm optimization (PSO) algorithm to synthesize and optimize an waveguide based inter-digital filter using resonating bars alternatively short circuited. Design, synthesis and optimization process is compared with the results obtained from EM simulation which is also compared from the same obtained experimentally. The design of a waveguide based Inter-digital filter using rectangular bars as its resonator elements is done using traditional synthesis process. Capacitance values of the resonators are evaluated using an Artificial Neural Network (ANN) model of the same with the geometry parameters of resonators as its inputs. Particle swarm optimization (PSO) algorithm is utilized to optimize the dimensional parameters of the resonators in order to obtain inter-resonator coupling coefficient values that can be used for the design of the broadband filter. The aim of the present research work is to design and optimize waveguide based inter-digital filter having rectangular bars as resonators for broadband VSWR BW. Electro-Magnetic simulations are performed using the theoretical design of the waveguide Inter-digital filter structure and compared for accuracy of the design and optimization process adopted here. The simulation results are in good agreement with those obtained using the ANN/PSO algorithm. The optimized design of the filter is developed by practical implementation in hardware and further characterized. Simulation and measurement results are compared to validate the design approach.
