The main feature of this system is that it is controlled by a fuzzy controller, accommodating its integration to a wide range of commercial inverter drives for lifts. In the present work, an extended analysis is presented, for the possibility to interconnect the regenerative braking system to a local microgrid, emphasizing on the effects that may emerge to the design and the normal operation of both the microgrid and the braking system. Moreover, the impact of this newly developed braking system will be assessed, in terms of driving system power quality at its connection point with the distribution network. Simulation and experimental results are presented, confirming the main outcomes of this work.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"28 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":"121837834","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 second ensures an almost constant frequency response throughout the entire common mode range of operation. Simulations show a maximum variation of only 9 % and 30 % for PM and GM respectively.

Nowadays the use of IoT in industrial robots is very popular contrary to humanoid robots. There have been a few attempts that combine IoT with humanoid robots but they have limited features. This paper proposes a novel open source platform Android application for controlling a humanoid robot, with more features than other research projects, in remote areas either behind NAT (Network Address Translation) or without it. The user can view what the robot is seeing through the Android application and can also move it. Additionally, our system has the ability to deliver real-time audio through our application. We envision that our proposed system is not only an attractive solution for many telerobotic applications but also an extensive educational tool in special needs education.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"104 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":"122624780","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}

Data backup, power fail alarms and generally embedded systems require high power density storage components with small dimensions. Graphene-based electrodes are very promising so as to construct thin film lightweight supercapacitors with high specific power. In this contribution, the development and electrochemical characterization of graphene-based electrodes with different fabrication parameters is conferred. In particular, both activated and un-activated carbon fiber was used as substrate and reduced graphene oxide as the active material. It was found that the activation of the carbon fiber offers superior performance in terms of gravimetric capacitance. Finally, Electric Double Layer Capacitors (EDLC's) with gravimetric capacitance of 2.12 F/g, energy density of 244.46 mWh/kg and power density of 54.6 W/kg after 600 charging-discarging cycles were fabricated.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"16 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":"129311006","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-bit output SDM pose further advantages in applications that would typically require a multi-bit DAC, since then only a single-bit DAC is required, which is much easier to design and is inherently linear in comparison to a multi-bit one. Look-ahead SDMs have been proposed to enhance the signal-to-noise-and-distortion-ratio (SNDR) and the output bandwidth of conventional single-bit SDMs. Multi-Step Look-Ahead sigma-delta modulators (MSLA SDMs) further reduce the hardware complexity required for the implementation of typical look-ahead SDMs while maintaining their performance advantages. In this work the architecture and the benefits of the MSLA SDMs are showcased. Finally the advantages of the MSLA SDMs over single-bit conventional ones are demonstrated and several hardware implementation choices for design optimization are discussed.","PeriodicalId":171095,"journal":{"name":"2017 Panhellenic Conference on Electronics and Telecommunications (PACET)","volume":"43 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":"128331217","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}
