There are different methods are used in detecting the error of codeword i.e. parity check etc. In this paper we will try to detect the error of codeword with the help of Cyclic Redundancy Check (CRC). This technique involves binary division of the data. The sender performs a division operation on the bits being sent and calculates the remainder. Before sending the actual bits, the sender appends the...
In the process of communication the information gets corrupted. Therefore, the signals received by the receiver which is different than the actual information signal. This paper stated that how receiver detect the errors in received signals and how does receiver rectify that error by using hamming code method. We have illustrated with the help of examples that how receiver identified which bit is...
The structure of a sentence can be seen as a spanning tree in a linguistically augmented graph of syntactic nodes. This paper presents an approach for unlabeled dependency parsing based on this view. The first step involves marking the chunks and the chunk heads of a given sentence and then identifying the intra-chunk dependency relations. The second step involves learning to identify the inter-chunk...
A single-layer, single-feed, metallic cylindrical cavity backed concentric annular-ring microstrip patch antenna (ARMSA) with circular patch has been investigated using a High Frequency Structure Simulator (HFSS) software. Variations in return loss with frequency for different values of air-gap height, radius of circular patch and radiation pattern of proposed antenna have been analyzed. The patch...
The effect of cylindrical metallic enclosure on the resonant frequency of a suspended annular ring microstrip antenna (ARMSA) is investigated using HFSS simulation software and theoretically calculated using modal expansion cavity model and circuit theory concept. Theoretical result shows close agreement with simulated results. Variation in resonant frequency with air gap height and inner patch radius...
The main problem of higher educational institutions is to increase the performance of their students. For this purpose, they always scan students' performance in the class test and quiz of different subjects and take appropriate decision like arrangement of extra lectures on conceptual topics so that they can improve student performance in the examination. They also face the problem to predict the...
Reducing latency for accessing web objects is a major challenge in Proxy Server and various techniques such as web caching and Web pre-fetching is used for it. In this paper we have integrated the approach of web caching and pre-fetching using sequential data mining techniques to enhance the proxy server's performance. The web access logs collected at squid proxy servers, can be used derive interesting...
The present paper discusses the design and development of low loss dual mode PIN diode phase shifter in MIC configuration for medium power scanned array radar. The paper discuses the design topologies to achieve the low loss in the phase shift bits and a hybrid innovative 3 diode configuration. The Phase shifter is designed to achieve 1.7 dB insertion losses in six-bit configuration for 12% of bandwidth...
This paper describes the challenges faced in language learning and use, with a focus on domain-specific vocabulary learning. We focus on the architecture and the presentation model of domain-specific knowledge components. The paper first discusses the significance of assistive mechanisms for vocabulary learning in an academic domain and then outlines two architectures for the presentation model. We...
Temperature dependence (2S-40°C) of speed of propagation in the frequency range 4.0–10.0 MHZ for various soft tissues (liver, spleen, heart and kidney) has been measured. The effect of fixation and the storage condition is also examined. It is found that in these tissues the speed of propagation increases with increasing temperature and the average temperature coefficient being 0.76 m/sec/°C. Examination...
