Efficient Temporal Association Rule Mining
Geetali Banerji1, Kanak Saxena

Abstract: Associationship is an important component of data mining. In real world applications, the knowledge that is used for aiding decision-making is always time-varying. However, most of the existing data mining approaches rely on the assumption that discovered knowledge is valid indefinitely. For supporting better decision making, it is desirable to be able to actually identify the temporal features with the interesting patterns or rules. This paper presents a novel approach for mining Efficient Temporal Association Rule (ETAR). The basic idea of ETAR is to first partition the database into time periods of item set and then progressively accumulates the occurrence count of each item set based on the intrinsic partitioning characteristics. Explicitly, the execution time of ETAR is, in orders of magnitude, smaller than those required by schemes which are directly extended from existing methods because it scan the database only once.

CP-ABE Scheme with extended reliability factor and load balancing in distributed n/w
Miss. Snehlata V. Gadge, Dr. S. T. Singh

Abstract: Several Data Security Methodology has been noticed, with recent adoption and spreading of data sharing. One of the most interesting and definitive approach is Cipher text-Policy Attribute-Based Encryption (CP-ABE).CP-ABE provides us with the indulgement of the access policies and its updates. It is used to set or control outsourcing of data sharing; it deals with the issues in CP-ABE. This solution allows encryptor to deals with the access control with respect to the access formula. The lacking of reliability factor lead to weaken the system, therefore we will amplify CB-ABE by introducing some factor. Key Generation center (KGC) and data storing center are the highlighted factors. KGC deals with the drawback of Key escrow problem. As KGC can decrypt the users data as per KGC`s concerns, causing threat to the data sharing Systems. This is not favorable for the distributed scheme where KGC is not trustworthy. Along with the key escrow problem, we will be concerning with the problem of key-revocation that is degradation because of windows of vulnerability. These issues are solved by exploiting the features characteristics of Architecture. The problem of key-escrow is resolved using 2-pc protocol. And Key-revocation is proceeding by using proxy encryption.

Matlab Modeling and Simulation of DFIG with Dump Resistor during Faulty Condition
Indrajit Koley, Sanjukta Dey(Sain), Chiranjit Sain

Abstract: In this paper the phenomenon of a DFIG during fault is described. Here a three phase fault is created by using fault block in MATLAB Simulink library and the converter which was connected at the rotor side of the DFIG(Doubly Fed Induction generator) is disconnected after the fault and is shorted by resistances. Then the rotor is no longer supplied from the voltage source inverter. Here the operation of both normal or fault duty is described. The assumption is that the mechanical system cannot respond during the short time of a three phased short circuit. Here equivalent circuits are built to model the fault response of DFIG.
Keywords: DFIG, dump resistance, equivalent circuit, faulty condition.

Effect of Coupling Chain Length on the Electric –Optic Properties of Siloxane Based Side Chain Liquid Crystal Polymers
Khalid Al. Ammar, Sura Al. Asadi

Abstract: A series of siloxane based side chain liquid crystal polymers have been prepared with asystematic variation in spacer length. Nematic liquid crystal polymers possess large optical nonlinearities owing to their large refractive index anisotropy coupled with the collective molecular reorientation. All the polymer exhibited a smectic phase, for which the Nematic -isotropic transition temperature increased as the spacer length increased. Electro-optic measurements are used to evaluate the threshold voltages for this series of polymers. It is found that with increasing spacer length (n) of polymer the threshold voltage is lowered and that the variation of the threshold voltage arises from changes to the intrinsic curvature elasticity rather than to differences in orientational order. A simple model is used to indicate the origion of the effects observed which appear to arise from the constraints offered by the coupling of the mesogenic units to the polymer backbone.

A strategy to choose process parameters for sustained operation of nutrient mist reactor to grow hairy roots
Ritu Ranjan, Sambashiva Katuri Rao, Rajesh Khanna

Abstract: Feed concentration and feed flow rate along with the relative durations of the mist-ON/ mist-OFF cycles are the important process parameters for the growth of hairy roots in a nutrient mist reactor. The paper presents guidelines for choosing these parameters for an efficient operation of the reactor with intermittent mist-ON/mist-OFF cycles. It is based on a theoretical model of nutrient mist reactor at the root bed level and its numerical simulation. This model describes the evolution of liquid holdup and concentration present in the root bed. One can also run the reactor with intermittent mist-ON and mist-OF cycles, at very low cumulative mist-ON duration for any given total run time to prevent any nutrient deficiency and water logging in the bed. It is found that in some conditions mist has to be switched on for only about 10% of the total runtime while the mist can be switched off for 90% of the total run time. The duration of both mist-ON / mist-OFF cycles are effected by the process parameters and thus, the ratio of mist-ON time to total run time, may not follow any fixed trend in some cases. The guidelines presented here will help in efficient operation and design of nutrient mist reactors.
Keywords: Drainage rate, hairy root, mist deposition, mist-ON cycle/mist-OFF cycle, saturation.

Page Rank Link Farm Detection
Akshay Saxena, Rohit Nigam

Abstract: The PageRank algorithm is an important algorithm which is implemented to determine the quality of a page on the web. With search engines attaining a high position in guiding the traffic on the internet, PageRank is an important factor to determine its flow. Since link analysis is used in search engine's ranking systems, link based spam structure known as link farms are created by spammers to generate a high PageRank for their and in turn a target page. In this paper, we suggest a method through which these structures can be detected and thus the overall ranking results can be improved.
