In the deployment of large scale observation systems in remote areas, when there is not a permanent connection with the Internet, the network requires distributed storage techniques for increasing amount of data storage which decreases probability of data loss. Unlike conventional networked data storage, distributed storage is constrained by the limited resources of the sensors. In this article, we will discuss strategies for, distributed data storage method by using PSO and K-means clustering mechanism organized with the binary decision tree C4.5 in the IoT area.<em></em></p> Negar Taheri Shahram Jamali 2020-02-29 2020-02-29 12 Study on Implementation of Smart City Using IOT https://www.i-scholar.in/index.php/CiiTNCE/article/view/207447 The new Internet of Things (IoT) applications is engaging Smart City exercises the world over. The essential pieces of urban progression for a splendid city should consolidate sagacious development, sharp industry, adroit organizations, wise the board and sharp life. The Internet of Things is connected to presenting sensors (RFID, IR, GPS, laser scanners, etc.) for everything, and interfacing them to the web through express shows for information exchange and correspondences. The precarious advancement of Smart City and Internet of Things applications makes various coherent and building troubles that decision for canny research tries from both academic network and industry, especially for the event of gainful, versatile, and reliable Smart City reinforced IoT. New shows, models, and organizations are in urgent must respond to these challenges. In this paper, a sincere undertaking has been taken to run through the nuts and bolts of „Smart Cities‟ and to beat the issues looked by common urban zones. Moreover, the most inspiration driving this paper is that of giving a close by review of the thoughts of wise urban networks and their applications in different fields. Specifically, this idea depicts the IoT propels for splendid urban networks and the essential features of a sensible city. S. Arpitha A. Kavya S. Keerthana G. Likitha S. Likitha P. Maltesh B.

Research in captchas implies advancement in AI making computers understand how human worries computer machine. it's a mechanism widely used nowadays for shielding web applications, interfaces, and services from malicious users and automatic spammers. every kind of Captcha are discussed during this paper and their advantages over each is given during a detailed approach. Captcha helps in blocking automated creations of email-accounts. Blocks Computers to vote automatically in online-polls. S. Likitha B.

Henceforth, for improvement in the teaching-learning process, the supervision style of headteachers needs to be evaluated. This study examined the perception of the science teachers on the synergistic supervision style of the science headteacher in a public secondary school. Moreover, the correlation between synergistic supervision and job performance was validated.  There are four components in synergistic supervision, namely dual focus, joint effort, focus on competence, and two-way communication. Results revealed that the science teachers were often satisfied with the components' dual focus, focus on competence, and joint effort.   For two way communication, the headteacher's rating given by the teachers was seldom satisfied. The level of job satisfaction of teachers was also studied. Results showed that teachers were often satisfied with their job. The Individual Performance Commitment and Review Form (IPCRF) became the basis for evaluation for science teachers' job performance. Based on the IPCRF, the ratings revealed that the science teachers performed their job very satisfactorily.  Statistical analysis showed that there is no association between the components of synergistic supervision and job performance.</p> Luningning M. dela Cruz Dennis G.
