Abstract: In this paper, we study the Peristaltic transport of MHD Jeffrey fluid in a non-uniform porous channel with the influence of slip, wall properties and heat transfer under the assumptions of long wavelength and low Reynolds number. The analytical expressions for the stream function, velocity and temperature are obtained. The results for velocity, stream function and temperature obtained in the analysis are discussed through graphs. It is noticed that the velocity and temperature decrease with increasing Jeffrey parameter . Further it is observed that the size of the trapped bolus decreases with increasing .

Abstract: Data Mining is concerned with the development and applications of algorithms for discovery of a priori unknown relationships associations, groupings, classifiers from data. Association rule mining (ARM) is a knowledge discovery technique used in various data mining applications. The task of discovering scalable rules from the multidimensional database with reduced support is an area for exploration for research . Pruning is a technique for simplifying and hence generalising a decision tree. Error-Based Pruning replace sub-trees with leaves .It uses decision class is the majority. In this paper we have proposed an algorithm DataAprori to generate scaled rules using the alarm technique. Network problems manifest themselves as an alarm sequence. Since network problems repeat more or less frequently, processing of alarm sequences from alarm history can be good base for creation of correlation rules that will be used in the future, when the same problem will appear. In this paper we have proposed DataAprori that induces a set of rules of the potential usage of the mathematical Apriori algorithm in fault management introducing logical inventory data in typical alarm by introducing the sequence detection processes. Experimental on real world datasets show that the proposed approach improves performance over existing approach in the form of High level-correlations (alarm sequences) which are detected in a telecommunication network.

Abstract: This paper proposes a hardware and a software interface for reducing the effects of Headlight glare. It proposes a Fuzzy Sensor and a Fuzzy Controller that uses fuzzy rule based design approach to reduce the Headlight glare emitted by the oncoming vehicles during night on the Highways. This in fact reduces accidents and puts the driver of the oncoming vehicle in a safety zone which might jeopardize the oncoming driver’s visibility. In the conventional vehicles the illumination is adjusted manually by the driver. The proposed approach has the hardware circuit fit on to the Windshield, which provides ambient light source to oncoming vehicle, there by not producing blinding effect on the vision of the driver . This Hardware has to be fitted on to all the vehicles, so that it reduces the occurrence of accidents. Microcontrollers are usually designed to interface to and interact with electrical/electronic devices, sensors and high-tech gadgets to automate systems. Microcontrollers are used for automated decision making. The PIC microcontroller has been used which reduces the intensity of light if it goes beyond tolerable limits, affecting the driver’s vision. The concept of Fuzziness has been applied to the sensor and the Controller. The light intensity of the oncoming vehicle is received by the Fuzzy sensor. This input light intensity is fuzzified and checked for the tolerance limit. If this does not lie within the tolerance limit, the sensor passes it to the Fuzzy controller which converts it to an ambient light source and then on defuzzifying the output. The software has been developed using MATLAB.
