Security systems are often being breached by intelligent thieves and hence there is always the need of new methods to be invented to provide proper security to the homes and also anywhere else. Use of innovative technologies will improve the security to a great extent till the technology becomes open to all. The aim of this paper is to provide the door access control and security by using IoT Server. The proposed system is implemented by using biometric scanner, password and security question with IoT. Remote operating of door access can be done by IoT with a smart indication. This system can be used in any applications, where security is the critical issue. © 2016 IEEE.

Electricity is one of the fundamental necessities of human beings, which is commonly used for domestic, industrial and agricultural purposes. Power theft is the biggest problem in recent days which causes lot of loss to electricity boards. In countries like India, these situations are more often. If we can prevent these thefts we can save lot of power. This is done using Smart Energy Meter (SEM). SEM is an electric device having energy meter chip for measuring the electric energy consumed and a wireless protocol for data communication. This paper presents a smart energy meter for an automatic metering and billing system. In this meter energy utilized and the corresponding amount will be displayed on the LCD continuously and communicated to the controlling base station. The feedback from the user helps in identifying the usages between authorized and unauthorized users which helps in controlling the power theft. Communication between user/household and substation is done using Zigbee. GSM network is used for sending SMS to the local authorities regarding the theft cases. This meter can work as either prepaid or post-paid meter. The proposed system replaces traditional meter reading methods and enables remote access of existing energy meter by the energy provider. Also they can monitor the meter readings regularly without the person visiting each house.

Short message service (SMS) blood bank provides the communication platform among the blood bank, blood donor and the person who require blood. The main purpose of the paper is to fulfill the blood request of the receptor with less hardship. In the existing systems the blood receptor will have to contact the blood bank and the blood donors individually which goes through time. Hence the proposed work aims to overcome this problem by allowing the receptor to simply send SMS in a predefined format, if the requested blood group is available at blood bank then the receptor will get contact details of the blood bank otherwise, he gets the contact numbers of the registered blood donors available at local database. The motivated individuals who are willing to donate blood can register his name by sending SMS, these data will be maintained in local database. The proposed work is implemented by using GSM modem, smart card CPU-Raspberry Pi 2 kit and IR sensors and Zigbee module. © 2016 IEEE.

In recent years, there has been an increase in video surveillance systems in public and private environments due to a heightened sense of security like, CCTV and RFID. There are several defects in the video surveillance systems such as picture is indistinct, complex structure, Poor stability, lot of storage space is needed to save the surveillance information and prices remain relatively high. This paper proposes the real time security surveillance system using IoT. The system design uses Motion Detection algorithm written in Python as a default programming environment. This significantly decreases the storage usage and save investment cost. The algorithm for Motion Detection is being implemented on low processing power chip Raspberry pi 2 and Pi camera, which enables live video streaming with detection of moving objects and get alarm when motion is detected and sends photos, videos to a cloud server directly using pi camera. When cloud is not available then the data is stored locally on raspberry pi and sent when the connection resumes. The camera is mounted on the motor and its movement (Left/Right) is controlled through IoT webpage by the user, thus providing user with enhanced view of the surroundings. © 2016 IEEE.

Anselme Payen has discovered cellulose after conducting rigorous experiments on wood. In this work an attempt is made to reinforce cellulose particulate into polyester matrix from 1.84-9.18 wt % and the lamina is manufactured by JMFIL technique. The fabricated lamina is cut into specimens for various tests as per ASTM standards. Tensile strength of 22.61MPa is achieved at 1.84 % of cellulose content in composites. Then the cellulose composites at 1.89% of reinforcement level showed 55.57MPa, 1.86GPa flexural strength, modulus respectively. 'C' kind of failure is visualized for all the specimens and volume fractions during impact test. The cellulose particulate is also analyzed for its morphology, size. © 2016 Author(s).

Increase in environmental concern towards sustainable development invites the development of new materials which are eco-friendly to satisfy various engineering needs. The present work introduces a new manufacturing method i.e. "Just Mold Fill and Immediate Loading" to prepare epoxy composites reinforced at different contents of particulate cellulose. The fabricated composites specimens are post processed and machined, tested as per ASTM procedures under impact load. © 2015 AIP Publishing LLC.

Increase in environmental awareness towards the sustainable environment invites the development of new materials which are partially/fully green. In this concern an attempt is made to extract the hybrid fibre from sacred grass which is botanically called Imperata Cylindrica. The fibre is reinforced into polyester matrix to make the composites for tensile test at different weight fractions as per ASTM procedures. At maximum fibre volume fraction the composites have shown a tensile strength, modulus of 26.59, 674.95. MPa respectively. Then the tensile properties of the composites are further compared with the composites reinforced with sacred grass leaf and petiole fibre. © 2015 Elsevier Ltd.

Increasing attention towards "sustainable environment" invited the development of new materials to satisfy the needs of the public with less/no damage on surroundings. In this regard a specific attempt is made by the author to do review and understand the performance of the variable vegetable fibres of okra which is botanically called 'Abelmoschus Esculentus' and their composites under various conditions of load. Further the results exist in the literature are also reviewed for the purpose of comparison. © Published under licence by IOP Publishing Ltd.

Nature supported with huge amount of natural materials to satisfy human needs, specifically in terms of fibres. Utilization of natural fibres in various engineering applications is a significant subject. In the present work an attempt is made to reinforce a specially grown long time dried hybrid okra fibre botanically called “Abelmoschus Esculentus” into polyester rein to fabricate and test the composites as per ASTM procedures. Then the performance of the composites is further compared with the composites reinforced with the okra fibre in as is condition immediately. From the experimental results it is observed that okra long time dried fibre reinforced polyester composites had shown reasonably good mechanical performance when compared with the composites reinforced with as is fibre. © 2015 American Scientific Publishers All rights reserved.

An increase in environmental concern invites the development new eco friendly materials having light weight and superior mechanical performance. In this connection an attempt is made to manufacture composites reinforced with long time exposed dora hemp fibre at ambient conditions into the unsaturated polyester resin. The fabricated composite specimens are processed at P1, P2 and P3 conditions to assess their mechanical performance as per ASTM procedures. Out of all the composites investigated in the present work the dora hemp composites at P2 have shown good tensile and flexural properties, whereas the highest impact strength is achieved for the composites at P1. Hence this class of natural fibre composites is suitable for making automobile components after thorough investigation of necessary parameters. © 2014 The Authors.
