This would allow the formation of large lakes that would create an \"artificial albúfera\" which will cover an area of about 1234 km2 in Gualicho and 650km2 in San Julián. These lakes will be exposed to tidal by means of an array with combination of a channels and four tunnels/chan. Gualicho and Only Tunnels in San Julián, which will be located between the sea and the lake. Taking the reference of Puerto San Antonio Este for Gualicho, the average tidal range reaches 6.73m [2], lasting 6 hs. 20 min. . In the case of San Julián, the tidal reaches 7,45m and lasting 6hours and 45minutes.

The high quality and diversity coupled with the cost reduction of equipment’s facilitated its utilization among scientists. Remote Operated Vehicles (ROVs) and Drift Cameras (DC) are the most used remote operated vehicles. In Argentina, despite cost reductions the use of remote operated vehicles is still scarce. On this work, a DC equipped with a novel system to measure objects is presented, together with data acquisition protocols and processing and a precision & accuracy test. The DC was built at low cost and operated satisfactorily from small boats up to 82 m deep in a wide range of visibility conditions. It was possible to identify and measure animals up to 2 cm of total length with an accuracy of 8%, estimate their abundances accurately and geolocalize any object or animal captured on video imagery with an error of 5 +- 2,16 m.","PeriodicalId":154805,"journal":{"name":"2016 3rd IEEE/OES South American International Symposium on Oceanic Engineering (SAISOE)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127079671","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 design and development of an AUV is an expensive and complex task. During the development of these vehicles both at the stage of physical design for construction, as in the stage of the navigation system design, it is critical to estimate and analyze the dynamic behavior of these vehicles in order to reduce design changes over the prototype, which it entails time and cost overruns. This work aims to determine the mathematical model of the AUV-ICTIOBOT, which is an underwater vehicle developed by the research group INTELYMEC of Engineering Faculty of the UNCPBA of Argentina. To propose an AUV model we use computational modeling using Computer-Aided Design (CAD) and Computational Fluid Dynamics (CFD).

In this paper, the performance of the acoustic signals encoded by multilevel CSS in an underwater horizontal link is analysed. For that, a channel propagation model based on ray tracing is used, where parameters for the San Jorge Gulf Argentina are included. The main goal of this is to analyse the transmission scheme based on acoustic encoded signals, in order to be used in a communication system, between a buoy in a surface and a group of sensors on the seabed, that form a sensor network for coastal monitoring. Other application of this scheme can be a positioning system, where a set of sensors of the network are deployed on the seabed in order to compute its position. The obtained results show a suitable robustness of the used encoding scheme based on Multilevel Complementary Sets of Sequences in a point-to-point link in shallow water, where it is possible to detect encoded signals even under hard conditions of attenuation and SNR.","PeriodicalId":154805,"journal":{"name":"2016 3rd IEEE/OES South American International Symposium on Oceanic Engineering (SAISOE)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115968654","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}

Therefore, the development of autonomous control systems is imperious, for fast decision making in unknown situations or environments. In order to achieve this, is necessary to solve the control and navigation problem efficiently. In this article two control techniques, previously used in AUVs, are compared, in order to apply one of them in the submarine ICTIOBOT, a development platform designed by the research group INTELYMEC of the Faculty of Engineering of the UNICEN. Firstly two controllers are designed, a PID with a Kalman filter for state estimation, and a LQG controller. An evaluation of the performance is done in simulation, with regards to different operation conditions. The results show that the LQG strategy has a better performance that the PID although the latter is computationally more tractable.","PeriodicalId":154805,"journal":{"name":"2016 3rd IEEE/OES South American International Symposium on Oceanic Engineering (SAISOE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128470433","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}
