However, dysphonia-changes in speech and articulation-is considered the most significant precursor as 90% of PD patients posses speech impairments. Multiple types of speech data have been used for PD detection. The multiple types of speech data includes different types of voice or speech samples for each subject, e.g., speech recordings of numbers, words, some short sentences and vowel phonations. Some of the previous studies pointed out that number samples show better performance while other concluded that vowel samples have complementary information about PD. Hence, this is still an open question that which type of speech samples contain complementary information about PD. Moreover, the drawback in these studies is that their methodology is solely based on one type of machine learning model. In this paper, we propose a more robust methodology based on multi-model framework which uses multiple types of machine learning models having diverse nature. For final evaluation of the multi-model framework, we propose to use two different evaluation criteria i.e., mean and majority voting. Based on the multi-model methodology, our study concludes that vowel samples posses complementary information for PD. Additionally, to further validate the findings of our study, we further used two other evaluation metrics namely Receiver Operating Characteristic (ROC) chart and area under the curve (AUC). The results of ROC charts and AUC further validated the fact that vowel samples possess complementary information regarding PD.","PeriodicalId":111615,"journal":{"name":"2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128384056","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 addition to the above-mentioned constraints, researchers have paid attention on some recently investigated issues caused by PV penetration including; reverse flow of power, voltage increasing along distribution feeder, Power quality problems, voltage control issue, phase unbalance, anti-Islanding detection difficulty and eventually Power losses. To ensure the stability and the safety of the grid energy source, it is important to consider some aspects avoiding partial or total unnecessary outage that might be caused by short term voltage drop. Proposing an efficient control and protection mechanism can help achieving these goals, since the penetration of Distributed Sources used to have important influence on the protection system. In this paper the inverter controller response was assessed under different grid voltage sag percentage, integrating low voltage ride-through (LVRT) capabilities and considering the impacts of High PV penetration in terms of fault contribution on a distribution network using PSCAD/EMTDC software.","PeriodicalId":111615,"journal":{"name":"2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116564628","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}

Badminton requires at minimum two players and it is impossible for an individual to practice badminton without support of another player. To allow an individual to train independently, a Shuttlecock Propulsion Machine has been developed. The Machine comprises a shuttlecock holder, a feeding mechanism, an ejecting portion and a tripod stand. This machine utilizes a flywheel mechanism in the ejecting portion for the propulsion of the shuttlecock. The machine involves two flywheels rotated by two high speed DC motors. The shuttlecock holder consists of a PVC duct and ascends in an inclined sequence to tilt shuttlecocks with hemispherical cork side over the feeding mechanism. The shuttlecock would be captured by the Robotic Jaw Gripper and fed into the ejecting portion. The flywheel diameter has been kept large enough to store maximum inertia for the propulsion of shuttlecock. The main aspect of the machine is that it can move in multiple axes. This machine design optimizes the speed of launching a shuttlecock and can be manufactured at a reduced cost compared to the similar machines available in the market.","PeriodicalId":111615,"journal":{"name":"2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128336433","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 have investigated two high performance bulk heterojunction organic structures based on P3HT: PCBM and PTB7: PCBM under illumination of 100 mW/Cm2-AM (Air Mass) 1.5G. The extracted performance parameters indicates that the structure (S2) based on PTB7: PCBM holds the highest power conversion efficiency of 6.47% with shot current density, Jsc= 9.78 mA/m2, open circuit voltage, Voc=0.898 V and fill factor, FF=73.65% when collate with the investigated P3HT: PCBM based structure (S1), which holds a power conversion efficiency of 4.52% with Jsc=7.92 mA/m2, Voc=0.791V and FF=72.31%. The investigation of optical absorption for both the structures has been performed and founded that structure (S2) based on PTB7: PCBM shows an excellent absorption of photons in the visible spectrum of light when analogized with P3HT: PCBM based structure (S1).

It tends to achieve the reconfigurability by switching different states of switches and results in altering the stub's radiation parameters. Both the slot and stub have different characteristic polarization and operating frequency. Thus, the antenna is joined with a dual band and polarization-dependent artificial magnetic conductor (AMC) surface to decrease the specific absorption rate (SAR) and progress the radiation characteristics. A flexible substrate is used in designing of this antenna. Simulations concluded that the SAR level is decreased when the AMC Surface is integrated with antenna, and it works as an isolator between the antenna and the human body. Two switches are embedded in the stub. While keeping both the switches off, i.e., switches behaving as non-conducting elements, the antenna tends to resonate on multiple frequencies covering three bands with gain enhanced at a certain level. This proposed antenna is wearable and proves an appropriate choice for Worldwide Interoperability for Microwave Access and Wireless Body Area Network for wireless body-worn devices.","PeriodicalId":111615,"journal":{"name":"2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116583889","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}
