The forecasting of ionospheric delays is tough and challenging low-latitude regions due to rapid temporal variations in ionospheric electron density irregularities. Hence, in this paper a non-stationary signal decomposition technique based on Variational Mode Decomposition (VMD), combined with Auto Regressive Moving Average (ARMA) called VMD-ARMA (VARMA) model is presented to forecast the ionospheric delay values 1 hour ahead. The performance of the proposed VARMA ionospheric TEC forecasting algorithm is tested during geomagnetic storms that occurred in June 2013. Three months GNSS data i.e., from 1 April 2013- 30 June 2013 is logged using GNSS Ionospheric Scintillation and TEC Monitor (GISTM) receiver located at Koneru Lakshamaiah Education Fondation, (K L E F), Guntur station (geographic: 16.37°N, 80.44°E), India. It is found that the VARMA model is 2-3% more efficient than the ARMA model in providing good forecasting accuracy during storm conditions. The forecasting results demonstrate that the VARMA version can be useful to forecast the ionospheric TEC variations at low-latitude regions during disturbed ionospheric space weather conditions also.","PeriodicalId":307218,"journal":{"name":"2020 5th International Conference on Devices, Circuits and Systems (ICDCS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131323646","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}

Due to heterogeneous and low intensity nature of CT image, manual image analyzing becomes difficult which leads to different problems like false positive detection, consumption of huge analyzing time, observer error, etc. Developing an efficient automatic Computer Aided Detection (CAD) system is essential to reduce the frequency of missed lung cancer nodules, make diagnosis simpler and time saving. The CAD system improves the accuracy of lung tumor detection and survival rate of the patient. In this paper, a fully automated model is presented for NSCLC nodule(s) segmentation from CT scan image. The proposed method follows four steps: (1) Preprocessing, (2) Automatic Lung Parenchyma Extraction and Border Repair (ALPE&BR), (3) Automatic lung nodules segmentation using Connected Component Analysis (CCA) and Threshold BasedMathematical Nodule (TBMN) refinement algorithm and (4) Nodules filtering using Hounsfield Unit (HU) value and true cancerous nodule extraction. The ALPE&BR method consists of Automatic Single Seeded Region Growing (ASSRG) algorithm for automatic lung parenchyma extraction and novel hybrid border concavity closing algorithm to get clear lung boundary. The proposed method successfully segments the true cancerous nodules by filtering out false region such as vessels, bone, fat, soft tissues, etc. The proposed method can provide the SN of 99.41%, SP of 99.97%, FPR of 0.019%, DSC of 0.98, and accuracy of 99.97%. These results are used to demonstrate that the proposed method outperforms the existing lung nodule segmentation method.","PeriodicalId":307218,"journal":{"name":"2020 5th International Conference on Devices, Circuits and Systems (ICDCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131366019","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}

In this paper, we just study the feasibility of energy from outdoor fan of air conditioning system using small wind turbine (rotor radius 0.25-5m), because nowadays air conditioning is the second largest energy consumption device among commercial as well as home appliances in Bangladesh due to climates fluctuation. Moreover, the extracted energy will store in electrochemical device to use this energy during load shedding. It not only helps to reduce tariff but also remove power cut-off tension and replace high price heavy and solar irradiance dependent on-grid rooftop solar system. We measured the outdoor fan’s wind speed using anemometer of various capacities such as 1 to 2 tons’ air conditioners. Later the model’s performance analyzes numerically by MATLAB software. It shows maximum mechanical power 40W at trip speed ratio 8. In addition, cost analysis has done to know economic feasibility.","PeriodicalId":307218,"journal":{"name":"2020 5th International Conference on Devices, Circuits and Systems (ICDCS)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124081435","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}

Beyond 10 nm scaling of MOSFET is introducing several limitations like short channel effect, drain induced barrier lowering, less Ion/off ratio etc. Instead of modifying the existing MOSFET technologies, recent new technologies are considered as future and as per prediction of the Global Market for carbon nanotubes report, CNTFET is going to make a severe impact in the semiconductor market. In this paper, first AC analysis is done by varying number of channels of GAA-CNTFET of Common Source Amplifier and results are shown in the form of a graph. Then AC analysis is performed by varying diameter of GAACNTFET and from the result of this analysis which maximum gain was obtained is chosen. Similarly, AC analysis is formed by varying oxide thickness (tox) and dielectric material (kox) and from the results of these analyses, the best-case gain is obtained for single stage, two stages, and three stages common source amplifier using CNTFET on 11 nm technology. In the frequency domain, it corresponds to 19.102 dB for single stage, 38.26 dB for two-stages and 56.34 dB for three stages.","PeriodicalId":307218,"journal":{"name":"2020 5th International Conference on Devices, Circuits and Systems (ICDCS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128189850","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}
