作者： Ayyappadas, C Shanu, O S Vijayan, Abhilash Mohammed, Irfan A Vishnu, V Shamnadh, M Assistant professor Department of Mechanical Engineering NSS College of Engineering Palakkad Kerala-678008 India M.Tech student Computer Integrated Manufacturing Department of Mechanical Engineering TKM College of Engineering Kerala-691005 India Assistant professor Computer Integrated Manufacturing Department of Mechanical Engineering TKM College of Engineering Kollam Kerala-691005 India

Copper MMCs reinforced with graphene, SiC and graphite flakes with varying mass fractions of 2.5, 5, and 7.5 wt% SiC, 2.5, 5, 7.5, and 10 wt% graphite and 0.2, 0.4, 0.6 and 0.8wt% graphene particles were fabricated through powder metallurgy route. The powder mixtures were blended and then compacted under a uniaxial pressure of 400MPa for both Cu-SiC and Cu-Gr composites and 600Mpa for Cu-Gn composites. Green compacts were sintered by microwave (MW) sintering process. MW sintering was performed at 950°C in open atmosphere with a heating rate of 25°C/min for all composites. Densification parameter (DP) was determined for all MMCs and a reduction in DP values were observed with an increase in weight percentage of reinforcement particles as a result of increase in porosity. Higher mass fractions of reinforcement particles in the Cu matrix tend to offer a diffusion barrier to copper atoms. Micro-structural analysis was performed using Optical and scanning electron microscope which revealed a homogeneous microstructure of all composites at low mass fractions of Sic, graphite and graphene. In order to detect the presence of any oxides of Cu and other elements, EDS analysis was carried out. Hardness data showed an increasing trend for Cu-SiC and Cu-Gn composites and a declining trend for Cu-Gr composites. Porosity has a significant effect on the electrical conductivity values of the composites.

the personalized web page recommendation for individuals is evident these days. Web servers are loaded with recommendation systems that analyze and recommend web pages to the users. They use data that are implicitly obtained as a result of web browsing patterns of the uses for recommending web pages. The cluster based association rule mining based system collects the web logs and generates a cluster of similar users and recommends pages to the users by actively analyzing them in the online. However, the time for analyzing it in online is more. To optimize this and increase the accuracy of the recommendation systems, a method that applies Naïve Bayes technique for clustering and firefly algorithm based similarity measure for optimization is designed. Web logs are initially clustered in offline by Naïve Bayes clustering technique. To find the similarity between the active user queries with other users in the same cluster in online, firefly algorithm based similarity measure is used. Firefly algorithm meticulously searches the generated cluster of web logs of the active user and recommends top pages. Firefly algorithm utilizes time efficiently, thus it is used for processing in online. When web pages are obtained, they are ranked and the top pages that are more relevant to the query are recommended. Efficiency of the system is evaluated using the measures like precision, recall, f - score, Matthews correlation and fallout rate. Experimental evaluation with real data set shows that the proposed system produced better recommendations and uses less time for computation in online.

This paper discusses about data transmission between hot machines and warm machines. We employ a Main Cloud Server (MCS) for this purpose. MCS provides a variety of services. User have to give request to MCS and it will provide necessary service. User will be sends request to MCS for data upload and the request will be sent to CSP and that allocates job to Virtual Machines. We need to use two machines such as HOT MACHINES and WARM MACHINES. Hot machines can handle current job. Warm machines can be idle state until the job is assigned. Every machines will be having three virtual machines. The user can raise the service request CSP to access the resources found in cloud. So, the CSP provides approve or rejection is accept by CSP, then user can immediately access or download the resource from cloud server.

The utility of a QR Code, is plenty in terms of usage to identify a particular entity. They are barcode of sorts that can hold a certain data set. Biometric security measures are one of the safest security measures, with fingerprint based biometric security being a rather easy and efficient way. In this paper, we discuss a way to efficiently check-in to a seat, during train travel by using a QR Code and fingerprint-based authentication system. A Quick Response Code (QR Code) can be used to mark one's attendance at their seat. Fingerprint authentication is the means to authenticate a person's identity without having to carry any form of physical identity proof along with them, during travel. Given the present system to check tickets is rather redundant and time consuming, having to manually check the ticket and identity of each passenger. By using this system, we can create a more efficient and less time-consuming system, that has much lesser probabilities of human error to occur.

作者： Subashini, P Chattopadhyay, Sancharee Sarkar, Sikta Sharma, Sushmita Assistant Professor Ug Scholar Department of Computer Science and Engineering SRM Institute of Science and Technology Ramapuram Chennai-600089 India

In 21st century, the medical industry is tending to reach its pinnacle, unattended and ignored medical emergencies still remain a loophole in the system. Hence this paper proposes the idea of medical heli-carriage. The proposed system promises to reach the patient irrespective of local traffic conditions, variable terrains and climatic conditions. It employs solar power as the primary energy source and also has sufficient battery backup in case of inadequate solar energy. Under any unlikely event of technical fault in the system, it will acknowledge the nearest medical heli-carriage available and the task will be rescheduled to the latter. It will be capable of carrying first aid medical instruments along with two institutional staffs and the patient. Under any critical situation, the patient will tap on the smart watch, which will send a signal to the nearest hospital. The GPS location of the received signal will be tracked by the hospital and fed into the heli-carriage so that it can reach the very location to the earliest. Hence, the system can prove out to be a revolutionary step in the modern medical industry.

International Conference on Communication and Electronics Systems (ICCES)

作者： Anidhya Athaiya Deepa Modi Gunjan Pareek M.Tech Scholar Department of Computer Science and Engineering wami Keshvanand Institute of Technology Management & Gramothan Jaipur Rajasthan Assistant Professor Department of Computer Science and Engineering Swami Keshvanand Institute of Technology Management & Gramothan Jaipur Rajasthan

Word Sense Disambiguation (WSD) is the procedure of selecting precise sense or meaning for a word in a given context. Word sense disambiguation goes about as an establishment to different AI applications as data mining, information recovery, and machine interpretation. The issue solicits to figure out which sense from the polysemous word is appropriate in a given context. Previously a few methodologies have been proposed for WSD in English, German and so forth, however, work on WSD in Hindi is limited. In this work, a genetic algorithm based approach is presented for Hindi WSD. The feature of dynamic setting window is used which contains left and right expression of a vague word. The cardinal supposition of this approach is that the target word must have a common topic in its neighborhood. For finding all possible senses of an ambiguous word, WordNet created by IIT Bombay is used.
