Opinion Sentiment Analysis
Get PDFAn automatic system to analyze the opinions/feedbacks of the people working in any organization is proposed. The proposed system does two major jobs: the first part extracts the most relevant/important aspects from the textual feedbacks provided by clients/managers/co-workers for all the employees having similar job profile and the second part measures the degree of positivity or negativity for all the extracted aspects for every employee and then an overall performance of everyone is evaluated. We have implemented the system to study the feedback of teachers. The proposed system is flexible and versatile than the existing feedback evaluation system of teachers where students evaluate the teachers on the predefined aspects decided by experienced and senior teachers. Our system, Faculty Evaluation System (FES) identifies strengths and weaknesses of teachers on all aspects which are important to students. This information may be used by higher authorities of the institute in identifying suitable faculty members for different academic and administrative activities of the institute in addition to the teaching responsibility
Intelligent Framework for Web-Service Testing
Get PDFWeb services provides a distributed computing architecture, with an emerging way of service oriented architecture (SQA). Here service oriented architecture is an interface to both computer systems and web services. Which implements an interaction with each other in new and different ways. According to service oriented architecture it virtually provides a platform for web services to communicate with each other. As it was an easy way for communicating with both clients and services. Many organizations and companies are either evaluating themselves into an enterprise information architectures, or they are in the process of getting adopt to the web services technology. As web services are platform independent it is playing a major role in the enterprise environment, and currently web services are widely accepted by many companies and organizations. So commonly web services possess some challenges to the enterprise environment. As a part of it web service must be tested before publish into a service oriented architecture. It involves large number of test cases, test scenarios that takes more time and effort. Testing management is needed so that it should control the time effort and should reduce the complexity of web service in a large software system, also in a real time world. Automation testing faces these challenges and fixes these issues. Automation testing has an ability to handle the complexities which are experiencing by the web services in a current environment. This paper presents the automatic testing strategies of a web service and detect the problems between both manual and automation testing. Finally results shows the proper effective report on improving the visibility of testing process based on the web approach to enhance the critical communication among multiple testing groups

Broadband Antenna for LTE Operation: A Novel Design Approach Using Meandered Strip Line
Get PDFThe broadband performance of an antenna for the LTE operation is presented in this paper. A novel design approach used to design the antenna using meandered strip line can be treated as a simplest and a cost effective approach. Due to the requirement of the bandwidth hungry applications, there is a smooth migration of the mobile technology from the existing services like GSM; UMTS to LTE is in progress. Thus a compact radiating structure can be preferred in many applications to improve the throughput performance of the multimedia service. The proposed antenna operates in the LTE 42 band. It shows the broadband performance centred at 3533 MHz with 112 MHz bandwidth. Bandwidth performance at this frequency is also found to be well suited to operate in the downlink frequency band at LTE 22. To determine the optimal performance of the antenna, a suitable threshold (S11 < 10 dB) is imposed. Gain and directivity of the antenna are 6.6 dB and 7.8 dBi respectively. Efficiency is achieved to 74%. Radiation pattern shows the best performance of the antenna. With the best performance achieved at this frequency, the antenna is advantageous to exploit in small cell coverage, LTE Hotspot and Indoor enhancement solutions. CST Microwave Studio Suite software is used to design the antenna. An ordinary 50 Ω transmission line is fed to the antenna. Other antenana parameters are also discussed for its performance
