The optical communication system has many advantages at long distance communication. Semiconductor optical amplifier based Mach Zehnder Interferometer plays an important role in fast optical communication. In this work the proposed SOA based MZI switch is used for all optical logic and arithmetic operations. In this architecture the continuous wave laser source and control signal pass through the Mach Zehnder Interferometer. Control signal at this wave length is split at the coupler and more power passes through one arm. The input data signal is fed to the coupler, which splits the signal equally. The resultant signals then propagates simultaneously through the two arms of the interferometer. This architecture can be used to perform all optical processing of signals like half adder, full adder, de multiplexer etc. MZI switch is a very powerful technique to realize ultrafast switching. The physical mechanism behind the working of MZI switch is cross-phase modulation (XPM). Here the gain saturation induced by beam reduces carrier density inside one SOA, which in turn increases the refractive index only in the arm through which the light passes. As a result, an additional phase shift can be introduced on the CW beam because of the XPM, and the CW wave is directed towards the bar port during each one bit. Now it is clear that in the absence of control signal, the incoming signal (CW signal) exits through the cross port (lower channel) of MZI. In this case no light is present in the bar port. But in the presence of the control signal, the incoming signal exits through the bar port of the MZI.Keywords

With growing usage of computer applications there is growing dependence of business over computer aided services like e-mails. The CRM or E-Mail based marketing companies are becoming pervasive. There is always a greater need to prioritize the e-mails which has direct impact on the ROI - Return on Investment to run these companies in a way that to customers satisfied. In this paper, a method is proposed to prioritize the unread E-Mails based on users' interest and priority. This is implemented in this system using agent technology. The Agent mechanism is guided using JADE Middleware and it's underlying architecture. The Intelligent agent used here can learn the interest and priority of the user and use this knowledge to rearrange the unread mails. The Text corpus in the mail would undergo tokenization and each token would be matched with knowledgebase by the agent. The 90 percent precision of the prioritization. Thereby, the E-Mails are ranked according to interest and priority of the user.Keywords

In an agricultural field, farmers have a wide range of diversity to select suitable fruit and vegetable crops. However, the cultivation of these crops with quality produce is highly technical. Most challenging for farmers is to differentiate between crops and weeds. The proposed method identifies the weeds by using leaf parameters such as shape, color, and texture. Pest/disease detection is also possible by detection of varied shape and color of disease affected crop leaves. In order to improve the accuracy of weed detection, need to develop a weed detection algorithm which could be supported in all the cases accurately. Adding on, crops face many diseases. Pest/diseases are seen on the leaves of the plant. To avoid misclassification of such disease affected plant as weed, a new algorithm is developed for disease identification and included in weed detection algorithm. Recognition of normal leaf, diseased leaf and weed is based on similarity measure.Keywords

This paper introduces a hybrid energy harvester generating electric power from both ambient heat and vibration. Harvesting energy from vibration was realized by piezoelectric effect Phenomena in Lead Zirconate Titanate (PZT) crystals, whereas the energy generation from heat was supplied by making use of Seebeck effect of n-type and p-type Bi2Te3 thermocouples. The industrial software Comsol Multi physics is used for the simulation. A total voltage of 17.024V was generated from the thermoelectric part and .4 V from the piezoelectric part of the device. Total power produced from the chip is predicted to be 1.91nW.Keywords
