Reddy","doi":"10.1109/ICCCSP.2017.7944097","DOIUrl":"https://doi.org/10.1109/ICCCSP.2017.7944097","url":null,"abstract":"Pulse Oximeter (PO) employed in critical care units is crucial equipment to measure the vital parameters like oxygen blood saturation levels and heart rate of the patient. Using PO device, required medical data is acquired using the photoplethysmographic (PPG) data utilizing PPG sensors attached on forehead/ to finger/at earlobe of the patient and then Ratio parameter (R) is computed pertaining to amplitudes of acquired red and IR PPG signals. Further, ‘R’ is used to estimate oxygen saturation levels with the help of calibration curve. Subject movements while recording the medical data may result in erroneous estimation of required estimation parameter and in turn may result in wrong diagnosis by the clinician. Reduction of Motion Artifacts (MA) component from raw PPG data recorded may guarantee error-free measurement of oxygen blood saturation level (SpO2). MA's can be removed from raw PPG signal (corrupted) using band pass filtering method, but the persisting in-band noise component cannot be removed. In this paper, authors propose a filtering method using tunable Q-factor wavelet transform (TQWT) to remove MA components. Advantage of TQWT sytems from the fact that, the realization of practical narrow band pass filter with a specific Q-factor value can be designed, which motivated the authors to use for this application. Experimental results have shown a good acceptance for the proposed method as the MA reduced PPG signals obtained are having efficient morphological features. SpO2 is estimated from MA reduced PPGs by utilizing the calibration curve. The superiority of proposed technique has been proved by comparing the experimental results with results obtained using basic least mean squares (LMS) method. Signal data can be acquired with different MA components (bending, horizontal and vertical movements of patient's finger) is considered for experiment analysis. Obtained SpO2 parameter calculations proved the efficacy of estimation technique in measurement of reliable and accurate SpO2, helpful for medical diagnosis.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133831737","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}

Thangaraju","doi":"10.1109/ICCCSP.2017.7944104","DOIUrl":"https://doi.org/10.1109/ICCCSP.2017.7944104","url":null,"abstract":"Speech signal contains two characteristics, system and source. When there is disturbance in vocal cord function, there is notable change in source characteristic. Despite the technological advances in the medical field, the voice pathologists use endoscopic methods to view the vocal cord flap movements for patients with infections and disturbances in vocal cords which are painful. This work is an alternative for classifying pathological voice from normal voice by evaluating the jitter and shimmer variations in the speech signal of an affected person. When there is any distortion in voice, it is reflected in the source characteristics. Pitch being the fundamental source characteristic, analyzing pitch helps us classify pathological voice from normal voice. Jitter and shimmer are derived characteristics of pitch. The glottal closure instants are better representatives of source compared to pitch. In this work, we have explored using the glottal closure instants to calculate the jitter, shimmer and other speech parameters instead of the pitch period. Analyzing these jitter and shimmer parameters for various pathological voices and normal voices help us to classify them. Experiments were carried out using a database containing normal and pathological voices. An accuracy of 85% was achieved for normal-pathological voice classification.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115026679","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}

Each day, along with the new technology comes a load of vulnerabilities waiting to be exploited. IoT (Internet of Things) is the latest trend and like all technology, it is open for exploitation. The most common attack which is used to bring down a whole network, without even finding a loophole in the security — DoS can be used to pull down any IoT network as well. In this paper, we propose a honeypot model for mitigating DoS attacks launched on IoT devices. Honeypots are commonly used in online servers as a decoy to the main server so that the attack is mitigated to the decoy instead of the main server. Here a similar methodology is used to avoid the whole IoT system from being shut down due to a DoS attack.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122737895","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}

Microstrip patch antenna is one such type that satisfies the above requirement. But the two main factors of an antenna namely the gain and the bandwidth are low for patch antennas. Usually the gain range of patch antenna is 1–2dB. The most straightforward way of increasing these factors involves the use of low dielectric substrate with increased thickness, but this inevitably leads to surface wave generation. As a result, sensible substrate thickness has to be employed. This paper presents pentagon shape patch antenna with probe feed for three different dimensions. The analysis is done using Ansoft HFSS software version 15.0. The performance parameters such as bandwidth, gain and return loss of the proposed antennas are compared.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117109537","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}
