One of the advantages of the proposed pixel design is the simplicity of the circuit due to the fact that it requires only four TFTs and one capacitor. The main advantage of the proposed pixel design is that the current of the OLED is almost independent of the threshold voltage of the driving TFT and well controlled. Also, the threshold voltage compensation technique is implementing with a static circuit, resulting to fast response time, similar to the conventional 2T1C response time which is the fastest circuit.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125171251","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, the small-signal transconductance parameter of the MOS transistors of current-mirrors is used for realizing the required resistors and, consequently, there is also an absence of passive resistors. The evaluation of the behavior of the proposed topologies has been performed using the Cadence IC design suite and the Design Kit provided by the Austrian Micro Systems 0.35um CMOS process.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114325210","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}

The conventional drivetrain is improved using an electronic differential to select the appropriate torque for the driving wheels. The results of the Ackermann geometry and the effects due to the relocation of the center of gravity are examined. For this reason, a microelectronic framework that consists of five nodes for monitoring and controlling the drivetrain based on sensor measurements and CAN communications is introduced. Experimental tests are performed and discussed.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"41 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115653607","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}

The different potentialities are due to differences on geometrical and physical characteristics of the sailboats but also on their sailing equipment. In order to have fair rating, the Offshore Racing Congress (ORC) has established the International Measurement System (IMS) which is based on a velocity prediction model developed by the Massachusetts Institute of Technology [1] [2]. For this model, one of the key parameters which has to be calculated and may involve serious difficulties, is the definition of the waterline plane of the sailboat. Creating a 3d point cloud of the boat using a 3d laser scanner could help to overcome this problem, as it provides high accuracy in points measurements. And also a 3d point cloud processing algorithm can be developed to define the waterline plane accurately. In this paper a novel methodology on calculating the waterline plane is presented, which is based on the 3d point cloud that represents a sailing boat.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116630827","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}
