 Abstract

Abstract: Knowledge about the uses of rubber tree was known to the people of Arunachal Pradesh since British era. They used to collect its latex at early age from naturally grown Rubber Tree (Fiscus elastica an Indian Rubber Bush) but this species is replaced by Hevea brasiliensis. First rubber was planted in 1980 for experimental purposes and it came to be used for commercial purposes since 1994. Now the rubber plantation is rapidly increasing in the state. The study area is the main latex production area in the state. The study covered about the development and present status of rubber plantation in area. To achieve the objectives of the study, GIS software like ArcGIS 10.3 and GPS has been used for digitizing and computing map of rubber cultivated areas in the state. For the reliability, information collected from sources and the field was analyzed by using MS word, MS excel and SPSS 18 package for generating appropriate qualitative and quantitative result. The information has been gathered through field investigation and 500 household from rubber cultivators were taken as sample. So far, state with 4,149.20 hectares (approx) of land under rubber plantation with 550 hectare under latex production. It is also found that, the rubber plantation has not only brought unprecedented increase in cash income to local farmers, but also accelerated economic stratification in the state. The farmers of the area are replacing the old traditional agricultural system after the introduction of the rubber plantation.

 Abstract

As today`s world energy transformation is less and loses of energy in high manner. normally in daily life the energy has been wasting in automobile field. In vehicle whenever brake applying the kinetic energy of the vehicle get wasted due to friction in the form of kinetic energy. The electric vehicle which designed recently with regenerative braking technology. This paper discussed about energy transformation process and regenerative braking process which recovery energy from kinetic energy into electrical energy. Regenerative braking technology include the electric motors, generators, battery for the energy conversion and storing purpose. It increase efficiency of the electric vehicle by saving the energy.

 Abstract

E-commerce websites often request the customers to write reviews, which helps the manufacturers to improve the quality of their products and other customers in choosing the right product or service. Each of these reviews may describe the different features of the products. Hence, the customer has to go through a large number of reviews before they can arrive to a fully informed decision on whether to buy the product or not. The manual analysis of such huge number of reviews is practically impossible. To solve this problem and for improving accuracy we need an automated approach which automatically extracts the product features from the reviews and determines if they have been expressed in a positive, negative or neutral way by the reviewers.

 Abstract

During the past few decades, the world has seen astonishing changes in the communication system due to advancement in technologies. Communication is a significant part of our everyday life. The increase in usage of multimedia services such as voice, images data, video and data communications requires great transmission capability. In optical communication, the channel (optical fibers) plays a vital role.Here we will discuss a commun-ication system that uses optical fibers. From a security point of view, these quick developments in information services must be secured from attacks. Subsequently, network security concerns have now been increased because of the immense measure of data that streams in a communication media. The exponential development in information throughput on the Internet demands the transmission of sensitive and confidential information over the optical networks. With this development, the possible risks of security of this sensitive data additionally increased as the tapping of the signal from an optical fiber could be effectively done by utilizing then expensive hardware. OCDMA is a technique which can be used to eliminate the problem of multiple user access and traffic growth on the web in optical systems. This paper will review the concepts of OCDMA, including its components, advantages, disadvantages, and different security concerns.

 Abstract

Ever-increasing demands of internet services for high capacity puts a peer pressure on conventional (C-band) frequency band and there is need to use wavelengths of Long band (L-band) to meet the aforementioned requirement. However, amplification of L-band through EDFA suffered from various limitations. Therefore, in this work, L-band EDFA amplifier is proposed with and without amplified spontaneous noise reinjection. Different physical parameters such as core radius, EDF link lengths, launched powers are varied and results are analyzed in terms of Gain, noise figure. Moreover, amplified signals are transmitted over SMF-28 (single mode fiber) at varied link lengths using return to zero and non return to zero linecodings and results compared in terms of Q-factor and BER.

 Abstract

Abstract: 3-chloro-2-methylaniline (3C2MA) is toxic for Human health and has been used as a precursor in industrial products, drugs, combustion products, pesticides, dyes, plastic, explosives, and rubber. Releasing effluents from these industries contaminates water. In this work, electrochemical degradation of 3C2MA was carried out in acidic solution on a platinum electrode (PE) by employing an eco-friendly technique, cyclic voltammetry. Kinetic parameters were evaluated for the reaction such as standard heterogeneous rate constant at the rate determining step, anodic electron transfer rate constant, electron transfer coefficient of reaction, and formal potential, the surface coverage of electrode were evaluated under the influence of scan rate. The nature of reaction is found to be adsorption as well as diffusion controlled. The result shows fast kinetics.

Abstract: In this paper we used first order ordinary differential equation in heat transfer analysis. The main purpose of this paper is to demonstrate how first order ordinary differential equation techniques can be useful in heat transmission such as heat conduction in solids, heat convection in fluids, radiation of heat in space. It teaches that first order ordinary differential equation can be understood from heat transfer analysis in solids, fluids, space. In fact it is too general for many applications in science and engineering field. Many of the parameters in our universe interact through differential equation. In this paper we will discuss the first order ordinary differential equation is a technique for analyzing the heat transmission.
