 Abstract

True random number generators (TRNGs) play a very important role in modern cryptographic systems. Field programmable gate arrays (FPGAs) form an ideal platform for hardware implementations of many of these security algorithms. In this brief, we present a highly efficient and tunable TRNG based on the principle of beat frequency detection, specifically for Xilinx-FPGA-based applications. The main advantages of the proposed TRNG are its on-the-fly tunability through dynamic partial reconfiguration to improve randomness qualities. The proposed TRNG has low hardware footprint and built-in bias elimination capabilities. The random bit streams generated from it pass all tests in the NIST statistical test suite.

 Abstract

Data encryption is used widely to ensure high security in open networks such as the internet. The fast development of cryptography research and computer technology, capabilities of cryptosystems such as RSA and Diffie-Hellman are inadequate due the requirement of large number of bits. The cryptosystem based on Elliptic Curve Cryptography (ECC) is becoming the recent trend of public key cryptography.In recent years, Elliptic Curve Cryptography (ECC) has grabbed the attention of researchers and product developers because of its robust mathematical structure and highest security in comparison to other existing algorithms like RSA (RivestAdleman and Shameer Public key Algorithm) and ELGAMAL algorithm. Elliptic Curve Digital signature represents one of the most widely used security technologies for ensuring un-forge-ability and non-repudiation of digital data. Its performance depends on an operation called point multiplication. The ECCDSA involves point addition and point doubling operations. It is found to be more secure in contrast to existing RSA and ELGAMAL algorithms.

 Abstract

Sensor networks have presently been an active research area mainly because of the significance of their applications. This project proposes to implement wireless sensor networks based Air pollution monitoring. RSPM (Respirable Suspended Participate Matter), Carbon Dioxide (CO2) and Nitrogen Dioxide (NO2) from the air are monitored as these gases determine the level of pollution. The use of MQ-6, MQ-135 sensors enabled us to monitor the Carbon Dioxide and Nitrogen Dioxide levels in the atmosphere. Also temperature and humidity is monitored using DHT11 sensor. The Atmega processor is used as the prominent platform for interfacing those sensors and the sensed data is processed wirelessly through Zigbee modules (Xbee S2C). The data hence received from the sensor device is simultaneously stored in a system as a help for a future reference in the levels of contamination. Thus with the help of the collected data, proper precautions can be taken to minimize the pollution levels in the air thus making human life sustainable.

 Abstract

In exhibit time inn housekeeping isn't restricted to cleaning and keeping up different surfaces in the inns however significantly more past that. My article investigates the present difficulties, best practices and rising patterns in lodging housekeeping which if executed well, could prompt higher development and savvy apparatus for the inn business. This paper has audited the scholastics and well known lodging housekeeping patterns. Lodging housekeeping need to address driving difficulties, patterns and best practices as eco-accommodating works on, outsourcing, IT wise housekeeping, preparing, maintenance of representatives, finance execution and Ergonomics systems. On the off chance that the lodgings actualize these patterns in a sorted out way, it can prompt inn development openings and long haul benefit. This paper expands new desperation to grow new patterns in inn housekeeping space particular for complex advantages

 Abstract

The Deccan traps offer excellent material for stratigraphic studies as the traps outcrop as an uninterrupted sequence of flows through of the terrain with occasional presence of few intertrappean beds. Krishnan (1960) has broadly classified the Deccan trap into lower, middle and upper stratigraphic grouped based on the distribution and relative proportion of intertrappean sedimentary beds an ash layers with relation to their height. The lower traps represent outlier part of the province. The middle trap comprises the central Deccan a Malwa plateau where as the western ghat near Maharashtra and Gujarat refers to upper traps. In the Asirgarh area the detailed stratigraphic aspects of the various lava flows exposed are study have been carried out to understand the flow stratigraphy of the lava pile. This detailed study based on megascopic and microscopic characteristic of the rock and geochemical analysis. The detailed stratigraphic investigation carried out in 465m thick lava pile exposed in the study area permit the broad division of Malwa subgroup into three formations namely Dahinala, Asirgarh and Amba. The formation boundaries are differing by characters such as field character, phenocrystic assemblages and appearance of giant phenocrystic basalt horizon (GPB). The Deccan traps offer excellent material for stratigraphic studies as the traps outcrop as an uninterrupted sequence of flows through of the terrain. Considering the vastness of the area and magnitude of the problem, a sincere attempt has been made in this study to establish the stratigraphy of Asirgarh volcanic. It is hoped that these results may provide a model to bring out the regional evolution and structure of Deccan Traps as a whole.

ABSTRACT: The current paper deals with the preliminary investigations on the use of sugarcane bagasse ash (SCBA) as partial replacement of cement in concrete, resulting in a binary blended concrete. The physical properties of blended cement, such as specific gravity are evaluated. Fresh concrete containing SCBA resulted in a mix with more water demand and hence, lower slump. From the evaluation of nearly 50 cubes and cylindrical specimen for compressive and split tensile strength it was inferred that 10% replacement of SCBA resulted in optimized value of replacement, without affecting the strength parameters of concrete.

 Abstract

Traditional routing algorithms require a definite path between source and destination. Many traditional algorithms fail in Intermittently connected network where there is no specific path to source and destination. Intermittently connected mobile networks are wireless networks where most of the time there does not exist a complete path from the source to the destination. There are many real networks that follow this model, for example, wildlife tracking sensor networks, military networks, vehicular ad hoc networks, Habitat monitoring sensor networks etc. Spray routing has been a good routing algorithm for Delay tolerant network. In this paper we will show community aware routing in spray technologies for Delay tolerant network. We also show the simulation results for Spray technologies using community aware routing as a mobility model.

 Abstract

This paper reviews various articles and documents on agricultural production. Agribusiness is one of the critical modern divisions in India and the nation's economy is profoundly subject to it for provincial maintainability. Agriculture contributes around 34% to the total national output (GDP) and gives work to around 36% of family units in the financial year 2016.Agribusiness influences atmosphere through outflows of ozone depleting substances (GHGs, for example, carbon dioxide, methane, and nitrous oxide. Agribusiness could be an answer for environmental change by the far reaching reception of moderation and adjustment activities.
