Humans use language for communication. NL is a prevailing tool used by the humans to convey the information. Natural Language Understanding (NLU) is a major challenge in Natural Language Processing (NLP). NLP is a part of Artificial Intelligence (AI). NLP provides a significant tool for communication. It attempts to produces noise free data and conversion of noise to text. NLU is having different levels. This paper presents the issue with respect to one of the level such as syntax analysis. To provide a solution for syntax analysis, dynamic fuzzy parser is designed and implemented to parse the English input sentences. Traditional approach of parsing is enhanced by applying fuzzy logic. This helps to know the syntactic correctness of the sentence. Penns tree bank parts of speech tags are used for the Parts of Speech Tagger (POS). POS tagger assigns the parts of speech tags for the input English sentence. Then these tags of the words are parsed using the grammar rules. Finally the result is displayed to represent the number of words parsed in a sentence with its associated fuzzy membership value. This parser produces Precision value of 1(100%), Recall value of 0.92 (92%) and F-measure value of 0.9583 for the sample of 50 correct and 50 incorrect sentences.","PeriodicalId":344188,"journal":{"name":"2018 International Conference on Current Trends towards Converging Technologies (ICCTCT)","volume":"273 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124234822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A single DC-DC converter suffers a higher current stress when it powers all the loads connected on the system. So in order to reduce the current stress on the converter and to increase the efficiency of the system, paralleling of DC-DC converters is employed. For paralleled converters it is necessary to share the load current equally among the converters and to provide proper voltage regulation on the load side. Parallel DC-DC converters require a special current sharing mechanism to share the current equally. This paper proposes a modified Master Slave Current sharing mechanism to adjust the duty ratio of the converters' PWM signal. The slave converter follows the reference current generated by the master converter. Precompensation has been employed for the master-slave current for proper gain control and stability. This paper also discusses the dynamic response of the system for various loading conditions. The proposed work was simulated using Matlab / Simulink platform. The hardware was implemented using PIC18f458 microcontroller and the results were inferred to have better stability and proper voltage regulation on the load side converters.","PeriodicalId":344188,"journal":{"name":"2018 International Conference on Current Trends towards Converging Technologies (ICCTCT)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126508956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Summarized video is a highly temporally condensed representation of video to give an overview of different activities present in the video so that we are extracting multiple events from original video to show multiple activities in original form. Here we are using motion of object and object tracking using blob matching over a video sequence. Summarized video also preserves chronological order i.e. relative timing between activities.","PeriodicalId":344188,"journal":{"name":"2018 International Conference on Current Trends towards Converging Technologies (ICCTCT)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122281465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the terminal phase of lunar powered descent, an existing proportional navigation law developed for missile guidance is modified. Presently in the algorithm, at the beginning of each guidance cycle, a normal acceleration perpendicular to the instantaneous missile-target line-of-sight is computed. The design augmentation proposed in this paper for lunar landing, introduces a polynomial acceleration term along the line-of-sight direction in addition to the existing normal acceleration which would then ensure terminal velocity requirements. It also has the capability to meet zero line-of-sight angles at the end of trajectory maneuver. Simulation results indicate that the developed methodology can be successfully utilized in lunar landing scenarios, especially in the terminal phases where the Lander orientation has to be vertical at the end.","PeriodicalId":344188,"journal":{"name":"2018 International Conference on Current Trends towards Converging Technologies (ICCTCT)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134046223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
