Foot step power generation using advanced harvard processor
No full textNow a day, the population is increased and their requirement of power is also increase. At this time energy is also wasted in many way. So we reforming this energy back to usable form is the major solution. So we can implementation of new project we have use the technique of power generation through footstep an a source or renewable energy. That we can obtain by walking on to the foot step, stairs. There system can be installed where the dense population area i.e.(railway station temple) In piezoelectric sensor are enable in this project design plate. This sensor current the pressure on it to a voltage. So we can use this energy or saving. This energy to batteries or other method that is no foot step power generation system we are generating power
Modelling and Simulation of Noise Effects in Power Line Communications
Get PDFPower line communications refers to the concept of transmitting information using the mains power line as a communications channel. Power line communication systems can be simply described as the distribution of data and other signals via electric power distribution wires. There are some challenges for communications over power lines, such as impedance variation, attenuation, channel transfer function varying widely over time, different kind of interference and noise in the system. This Paper deals with the noise scenario modelling approach and modulation schemes for the PLC system
Automatic station announcement system in Railways
No full textThis paper focuses on developing an intelligent system for passengers to identify location, in which sensor senses every location using GPS receiver. The system announces each and every station to all passengers through speaker inside the compartment and the passenger easily to identify their destination. This GPS receiver is capable of identifying the location in which it was present in the form of latitude and longitudes. The GPS gives the data received from the satellites. For this information the GPS communicates with at least three satellites in the space
Design and Analysis of FIR Filter Performance Based Multi Stop Band Technique for Mobile Receivers
Get PDFThis paper introduce a novel Finite Impulse Response (FIR) filter design based Equiripple multi stop band technique to overcome the adjacent band interference in the mobile communication receivers. The performance improvements of FIR in the band of interest plav vital rolls in the receiver path due to critical pass band in new communication receivers. Hence, the filter order and stop band stages could be used to optimize the filter response with minimum error in the desired band. To reduce the pass band ripple in the filter response, multi stop band could use bv insert different weights in different band in the filter response. Furthermore, in the pass band region, the weights has been set to thirtv time more than stop band weights in order to compensate the adjacent band rejection as well as blocker region. The simulation results shows important development in the pass band ripple by 20% and blocker requirements by 15% compared with traditional FIR filter design. The suggested techniques promising to enhance and support the current and future communication receiver’s requirements
Van der Waal's Equation of State in Analyzing Viscous Dark Energy Models with the Property of Variable G and Λ
No full textIn physical cosmology, cosmological inflation describes a theory of exponential expansion of space in the early universe. The various cosmological features of the model considered are analyzed. Inflation explains the origin of the large-scale structure of the cosmos. Here in this paper, a cosmological model is considered with the number of moles (n) together with volume (V) in a gas sample that obeys Van der Wall's equation of state exhibiting the property of variable Cosmological and Gravitational constants (G). The cosmological and gravitational constants and the volume V in the gas sample considered that obeys Van der Wall's equation of state increase exponentially with time whereas the energy density and n, the number of moles in the specified gas sample, decrease exponentially with time. The rate of mass creation during inflation is found to be very large suggesting that all matter in the universe was created during inflation. Inflaton is the hypothetical field responsible for exponential expansion i.e., inflation
Design and fabrication of angular post JIG
Get PDFAn objective of the mass production is to increase the productivity and the accuracy. This is done by reducing the set up cost and manual burnouts. Thus mass production can be acquired by the use of jigs. For large scale production of unlike materials a lot of time is wasted in start of the device and clamping the device. An experimental approach method is regularly practiced until the axis of the hole is properly line up with the axis of the drill. In such a situation a division of time is being wasted to maintain the accuracy. This paper is mainly composed of design and fabrication of the Angular postjig which cover the absolute design to the described dimensions of the work piece and would make the production process easier
A Two Phase Interleaved Boost Single Stage PFC Converter using Flying Capacitor
Get PDFThe equipment connected to an electricity distribution network customarily needs rectification. In order to decrease DC voltage ripple, a Single phase diode rectifier utilizes a large electrolytic capacitor which yields a non-sinusoidal line current. So power factor correction (PFC) techniques are required. The boost topology is utmostwidespread than others in PFC applications. Thus a two phase interleaved boost single-stage PFC converter using flying capacitor is proposed in this paper. Due to its interleaved structure, the proposed converter can operate with reduced input current ripple and peak switch currents.The proposed system is simulated in MATLAB/SIMULINK and the performance parameters such as power factor (PF) and total harmonic distortion (THD) are computed
Analysis and Exploring of different recent trends in processing of Big data
Get PDFBig Data is a whole new concept in information technology driven computing world that manages large and complex datasets through certain data mining processing tools and functional models. Research suggests that tapping the potential of this data can benefit businesses, scientific disciplines and the public sector – contributing to their economic gains as well as development in every sphere. The need is to develop efficient systems that can exploit this potential to the maximum, keeping in mind the current challenges associated with its analysis, structure, scale, timeliness and privacy As we all know the process of data mining is knowledge driven discovery process through which we can extract relevant information about a particular matter of subject. Big size datasets have numerous velocity and volume so it demands research techniques to extract useful information. As the complexity of data increases, there is more challenging work for us to implement big data methodologies. Enterprises face the challenge of processingthese huge chunks of data, and have found that none of the existing centralized architectures can efficiently handle this huge volume of data. This research highlights the concept of Big Data used in datasets, its present scenario place in industry, hidden truths behind development of big data and what will be the future of big data in coming years
A brief review on speckle noise reduction techniques for ultrasound images
Get PDFSpeckle noise, typically occurs in coherent imaging systems such as sonar, laser and ultrasound imaging, is an unwanted aftereffect of the image formation process in coherent imaging .Speckle reduction is an important issue for analysis of ultrasound images. In ultrasound imaging system, the presence of speckle results decline in image quality and makes it difficult for human interpretation and diagnosis analysis.Numerous methods for speckle suppression were proposed. In this paper we have given the overview of the speckle noise reduction modelalong with various filters which are commonly used for speckle reduction needed in ultrasound images. As speckle noise is dominated in ultrasound imaging, there is need of de-noising the ultrasound images before segmenting out the tumor regions. As border detection of these tumors should be highly accurate as final results of segmentation are dependent on it. Further we will explore the tumor edge detection and segmentation of infected liver ultrasound images
