Abstract

Sandal (Santalum album) seeds from various seed sources show significant variation morphologically and physiologically. Data on seed parameters (seed length, seed width and seed weight) showed significant amount of variation among different seed sources. Coefficient of Variation (CV) which helps in comparing variability among different provenances has been calculated. Some of the outstanding trees may be selected from those provenances which showed highest CV for different seed characteristics and may be incorporated as base population while establishing second generation seed orchards of S. album at different places as a pre-requisite for formulating multiple population breeding strategy in S. album.

Abstract

Our paper proposes a decentralized access control scheme for storing data or file in cloud securely with anonymous authentication. Authenticity of the content will be verified without knowing the user’s identity with the help of attribute based signature. Data will be encrypted under attribute based encryption and it will be decrypted only for users with attributes specified by the access policy using their key. Encryption and decryption keys are provided through decentralized scheme with two or more KDC’s and access control is provided by access control schemes which defines who have access to data.

Keywords

Access Control, Cloud Storage, Attribute Based Encryption, Attribute Based Signature, Decentralized.

Abstract

An ad hoc network is a group of wireless mobile nodes, in which individual nodes cooperate by forwarding packets for each other to allow nodes to communicate beyond direct wireless transmission range. There are many protocols are there routing compare to standard protocols security enabled protocols are few. There are lot of security types one of the types is secure the route which packets flow through. Secure routing protocols extended from standard protocols. This paper compares four protocols, two standard and two secure protocols that are extended from the standard protocols. The two standard protocols are AODV, DSR and two security extended protocols are Ariadne and FACES by using NS2 simulator. AODV and DSR are basic protocols and they are already implemented and compared in many situation. FACES algorithm works by sending challenges and sharing friend Lists to provide a list of trusted nodes to the source node through which data transmission finally takes place. Ariadne is a secure on-demand ad hoc network routing protocol. Ariadne prevents attackers or compromised nodes from tampering with uncompromised routes consisting of uncompromised nodes. Two scenarios are consider in MANET and at last conclusion will be presented, that the efficiency of the secure protocols over standard protocols.

Abstract

Mobile Ad hoc Network is a self-creative, self-organizing and self-administrative dynamic network topology with heterogeneous collection of mobile nodes that communicate with each other in the absence of fixed infrastructure or central administration. MANET devices are competent to perceive the occurrence of other devices that facilitate communication and sharing of data and service. Determining the throughput capacity of each device is a major concern in MANET since the topology is unpredictable. The chief idea is to attain the maximum accurate optimal per node throughput capacity of MANET through all the combinations of transmission range and packet redundancy in heterogeneous network. The convoluted packet delivery method in MANET uses Automatic Feedback Control and Markov Chain Model to achieve the optimal throughput capacity. Transmission power of each node can be manipulated to amend to specified transmission range and limited packet redundancy. Increasing the transmission power of the each node improves the throughput capacity.

Abstract

Soil is considered as one of the most valuable natural resources whose pH value is used to describe the acidity or basicity which determine the nutrient availability and ultimately plant growth. Fifty soil samples were collected and their type was determined by using digital image processing technique. Soil colour is visual perceptual property and their types can be determined using. Red, green, blue values. Soil colours are the parts of visual perceptual property where values of red, green and blue (RGB) provide a clue for different types in soil. For giving input as images, digital camera was used. On the basis of RGB grey values, pixels values and, results are estimated.

Keywords

Acidity, Basicity, RGB Values, Soil, Digital Camera.

Abstract

The main objective of this project is to propose a mobile solution for those students who are registered with senior project designer in the course of Bachelor engineering technology program. During the process of registration the students are free to choose the projects supervisors who are flexible and committed to them for successful completion of their project for handling all tasks of the project which includes but not limited to the selection of title of the project, methodology used, budgeting for final completion of the project, analysis of the result and successful tests of the project. A mobile application for students interested in doing projects has been designed, developed and tested for android platform. This project describes the algorithmic progress of design and development techniques process of m-research application which can be utilised as an integral component of m-learning model of engineering education for senior design project anywhere and anytime.

Keywords

Mobile Application, Android Application Development.

Abstract

Field experiment was conducted to study the residues of pendimethalin in edible parts of radish and its persistence in soil. At harvest in both the seasons of winter and summer more than 98per cent of initial deposit of pendimethalin was dissipated and observed half life in radish field was 6.45 days and 10.03 days for pendimethalin applied as pre emergence @ 0.5 and 0.75 kg a.i. ha^-1, respectively. In radish tubers the detected residues of pendimethalin were 0.0026 mg kg^-1 and 0.0063 mg kg^-1 during winter season and 0.0027 mg kg^-1 and 0.0056 mg kg^-1 when pendimethalin applied at 0.5 and 0.75 kg a.i. ha^-1, respectively.
