Harmonics Reduction of a Single Phase Half Bridge Inverter
Get PDFThis paper displays a way to deal with minimize the sounds contained in the output of a solitary stage half scaffold inverter. With a perspective to decreasing Harmonic a LC low pass filter is utilized which hinders the music and irrefutably passes verging on sinusoidal yield at the yield terminal. A representation of Fourier Transform has been given in this paper with a specific end goal to see both the basic and music part decisively. It has been found from recreation that the Total Harmonic Distortion (THD) previously, then after the fact the application is 44.999% and 0.0183% separately. That is the reason, this LC low pass channel is very compelling to diminish THD of a 1-stage half extension inverter
An Enhanced Image retrieval Technique based on Edge-Orientation Technique
Get PDFWith the tremendous development in Networking and Multimedia technologies, Image Retrieval plays significant roleand is used for browsing, searching and retrieving images from a large database of digital images. Image Retrieval techniques utilize annotation methods of adding metadata such as captioning, keywords or descriptions to the images. The manual image annotation is much time consuming laborious and expensive.As the data bases size increases, annotation becomes a tedious task. Thus automatic image annotationhas drawn the attention of the researchers in recent years.. The increase in social web application and the semantic web drawn attention of researchers in the development of several web-based image retrieval tools. This paper presents an easy, efficient image retrieval approach using a new image feature descriptor called Micro-Structure Descriptor (MSD). The microstructures are defined based on an edge orientation similarly while the MSD is built based on the underlying colors in micro-structures with similar edge orientation.In this method of Image retrieval the MSD extracts features by simulating human’s early visual processing by effectively integrating color, texture, color lay out information and shape. The proposed MSD algorithm has high indexing performance and low dimensionalityas it has only 72 dimensions for full color images.The technique is examined on Corel datasets with natural images; the results demonstrate that this image retrieval method is much more efficient and effective than reprehensive feature descriptors, such as Gabor features and Multi Texton Histograms

Virus Attack Identification And Representation In Sensor Network
Get PDFClusters consist of circulated sensors and motor that interact with each other via wireless network. The use of open wireless intermediate and unattended deployment leaves these systems vulnerable to intelligent adversary whose goal is to disrupt the system performance. Here we study the virus attack on a networked control system, in which an opponent establishes a link between two physically different areas of the network by using either high-gain antennas, as in the out of band, or colluding network nodes as in the in-band virus. Virus allow the adversary to violate the timing constraints of real-time control systems by first creating low latency links, which attack network traffic, and then delaying or dropping packets. The requester and responder in between the data sending through a transport channel then data can be destroyed or modified, so to avoid those problems we are proposing a new system by using NS2 features. Our approach is based on the analysis of the two-hop neighbours forwarding Route Reply packet. To check the validity of the sender, a unique key between the individual sensor node and the base station is required to be generated by suitable scheme. In our proposed work detection of virus attack is done through observing the performance of the route under various metrics those are packet delivery fraction, end-to-end delay and throughput. If the route having high end-to-end delay and low packet delivery fraction and low throughput that route must contains a virus nodes. So we can avoid those routes in the routing

Effect of nano particles on air conditioning compressor performance
Get PDFNano particles are found to attract the attention in the recent years due to their diverse uses. Addition of metal or non-metal oxides to a base fluid leads to a different working fluid called NANO FLUID. Addition of Nano particles lead to change in both transport and thermal properties for fluid. In a traditional air conditioning system, there will be certain amount of lubricating oil that is carried away by the refrigerant in the compressor. So certain amount of lubricating oil circulates along with the refrigerant in the air conditioning circuit. If the solubility of lubricating oil in the refrigerant is low, there is a danger of accumulation of lubricating oil in the condenser. If the solubility of lubricating oil in the refrigerant is high, refrigerant washes away all the lubricating oil in the compressor and there is a danger of abrasion in the compressor. There is a danger of sedimentation of Nano particles in compressor if it is not dispersed properly in the oil. If the Nano particles are not correctly dispensed, there is a danger of their interference with environment. Nano particles are found to hinder the growth of plants. They are carcinogenic and hence care should be taken to handle them judiciously. Economic issues regarding the usage of Nano particles have also to be considered as they are quite expensive.The refrigerant used in the air-conditioning setup that is used for testing is R-410a. The refrigerant R-410a is azeotropic suggesting that the phase change temperature does not remain constant as in the case of traditional refrigerants. Temperature of the refrigerant (R-410a) decreases during the phase change. The refrigerant used in the air-conditioning setup that is used for testing is R-410a.
