We decided to conduct a topographical synthesis instead of a nontopographical synthesis as it takes more parameters into account to create a more accurate design. We started by comparing some basic cells like inverters and register banks to understand the main differences between the two technologies. Several approaches were considered at this point to understand how different synthetization parameters affect the chip performance and characteristics. These different approaches were focused on time, power and area, and balanced configurations of synthesis flow. Finally, after comparing the performance given by the different approaches in basic digital structures, the balanced approach was implemented in 32nm and benchmarked with the 500nm implementation. Our conclusions were consistent among the various tests conducted and by downscaling we can expect a 10x increase in the clock frequency, a 100x decrease in power consumption, and around a 300x decrease in the area while using the 32nm technology. As a result, we developed a method to fairly compare complex systems to allow a designer to consider if the benefits justify the costs for a technology change.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131362238","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}

Path-planning and collision prevention routines are essential for a reliable operation of these multi-robot platforms, so increasingly complex control algorithms can be proposed, designed and tested. This paper describes the recent progress made on the functionality of a mini-sized multi-robot testbed that runs based on ROS (Robotic Operating System). A high-level path planner, a collision prevention routine and motion controllers are proposed as part of the expansion to more complex applications that can run on the testbed. A PID-based orientation controller and an Inverse Kinematics position controller are designed and compared as viable solutions for following the waypoints generated by the high-level path planner. Improvements on software modularity, scalability and the addition of an extra mobile agent also comprise the main improvements for this new iteration of the testbed. The results of the path-planning routine, as well as the performance of the motion controllers are presented and discussed.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115181608","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}

Some of these with congenital malformations or forearm amputations suffer from difficulties within society to carry out their activities of daily living. Many times, they choose to use a cosmetic prosthesis, since a bionic one is very expensive. Today, thanks to 3D printing, it is possible to manufacture affordable bionic prosthesis. For this reason, the innovative research was carried out from 2019 to 2020 under the supervision of the School of Mechatronics Engineering at Ricardo Palma University, it was designed and developed in the Digital Systems Laboratory resulting in iROD, a bionic prosthesis for a person with amputation at the level of the middle third of the forearm applying EMG signals. In addition, this device captures EMG signals from the forearm using dry electrodes for greater patient comfort. For the development, the biomechanical concepts of the human hand were used, where SolidWorks was used for the mechanisms and then to be printed in 3D, Eagle for the electrical and electronic system, and Arduino IDE for the control system. This prosthesis was designed for Mr. Franz Dioses, a person with an amputation at the level of the middle third of the forearm, helping to carry out his activities of daily living. In conclusion, this bionic prosthesis is the functional prototype, being the beginning of a more advanced one, improving the mechanical system and including control with artificial intelligence. It is proposed to start in September 2021 to design and develop these improvements.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133552851","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}

Also, this control represents a significant challenge because of a constantly varying section with height and its nonlinearity, so many control schemes were carried out. To obtain the linear model for the conical tank, first technique is the empiric linearization from data of the process. The reaction curve method is used, and the characteristic parameters are obtained. Another method is the coordinate transformation in the system is decomposed into two nonlinear functions g(x) and q(v,x). Consequently, using both linearization procedures, a sliding mode controller is designed and applied to a conic tank to compare the performance obtained from each technique. The proposed controller shows robustness and rejects the disturbances better than the typical PID controller.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127237104","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}

Test signals were obtained from two electromagnetic transient programs: a) RSCAD for RTDS, which is a real-time tool; b) Matlab/Simulink, for off-line tests with an injector. Furthermore, test signals were obtained using two models for the faulted transmission line (Bergeron model and a frequency-dependent model). The tested relays were a travelling wave relay (SEL-T400L) and two distance relays (SEL-421 and Micom P545). The tests with RTDS were performed at the low-level interface of SEL relays, whereas the tests with the inj ector were performed at the usual voltage and current inputs of distance relays. In general, the results are useful to emphasize the need of contrasting the expected output signals with oscilloscope captured waveforms, because the expected output signals (as shown by injectors' interfaces) can be different than the real injected signals. Despite this fact, the observed behavior of tested relay functions can be considered adequate.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127254534","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}

As a proof of concept, we monitored the magnetic field and seismic signals in the moderately active Chiles-Cerro Negro volcanic complex in Ecuador during a first survey in October 2020. Distinct anomalies in the magnetic field were observed in the geothermal areas in Chiles volcano when the seismic activity was high.
