This approach targets to provide rapid assistance to possible cases caused by the Aedes mosquitoes minimizing the time of the processes of identification, evaluation and intervention. Basically, the algorithm focuses on the rapid decision for a better localization of pregnant women away from infected areas where there is one suspected case already manifesting Zika symptoms. The algorithm assumes that at least there is one suspected case of Zika virus. Assuming the case that this person performs a phone call to health specialists, then an optimized route for a rapid attention is drawn. By assuming the scenario that the suspected is already a confirmed case, the knowledge of its Geographic localization might be also crucial to focus efforts to identify the vulnerable human groups living around it. The simulations have shown that given an initial sample of suspected cases, the application systematic of the algorithm might avoid complications in a 90% of identified pregnant women population.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"28 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73086524","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}

For radars, the ability of the device to mitigate the effects of noise and interference is of great importance because it will determine its performance. Radars may suffer from attacks aimed to hinder their performance, known as jamming attacks. In this context, noise jamming attacks are a very common type of attack, thus reducing their effect is fundamental. Due to this fact, simulation and analysis of radar performance in different scenarios could help decrease possible threats. For this reason, in this paper the performance of radars in noise jamming environments is evaluated. To achieve this, a radar system, jammer attacks and anti-jamming algorithm are modelled and evaluated through simulations. The models and algorithms developed in this work could aid in the process of performance test and analysis of radars and could be used as a design platform of radars and jammers to reduce developing and implementation time.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"11 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74818797","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, in recent years the development of networks defined by software (SDN) has caught the attention of the scientific community, mainly because of the flexibility it presents in its model of centralized management, which facilitates the development of solutions according to demand of the network and / or users. Mininet is one of the most commonly tools used for the study of SDNs, as it allows to recreate data networks that can support various topologies and protocols. Nevertheless, like any other emulation software Mininet has limitations due to the restrictions of the hardware/software platform where it runs, which prevents it to scale to large networks. We present a characterization of the performance and scalability of Mininet via an experimental analysis. For this purpose, we used a typical topology for large data centers. The results let us conclude that, under some restrictions, Mininet gives results in accord with the theoretical expectation. In other cases, the emulation platform exhibits strong dependence on the performance of underlying hardware/software system as well as on the operation mode of the SDN controller used in the network.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"60 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84439709","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}

Muller-Karger, Euro Casanova, Thalia San Antonio","doi":"10.1109/ETCM.2016.7750871","DOIUrl":"https://doi.org/10.1109/ETCM.2016.7750871","url":null,"abstract":"The Monte Carlo method is widely used in the field of biomechanics to study the variability of diverse parameters, like tissues properties, magnitude and direction of loads, kinematic of joints, among others. In particular, the failure of bone tissue, which is the target of this investigation, has been extensively studied; however, it is common to find in the literature realizations of Monte Carlo experiments with arbitrary sample size, or with a convergence criterion for which a statistically valid confidence level, or interval, is not defined. These strategies lead to results with presumed low, but unknown uncertainty. One option to address this problem is the acceptable shifting convergence band rule which, if appropriately configured and applied, serves as a convergence criterion with an implicit confidence level. However, in order to ensure a desired confidence level, it is necessary to determine the correct parameters for the method. As the typical biomechanical simulation is very time consuming, it is not advisable to calculate these parameters with the full model. Therefore, it is recommended to run a Monte Carlo experiment with a simpler, faster to simulate, model that is probabilistically similar to the full model. In this work, a pilot experiment is developed in order to compute the parameters required to stop the Monte Carlo simulation of the failure of bone tissue, with a desired confidence level. Two different failure criteria are applied, one with two and the other with three input probabilistic variables. Also, the variation of the convergence parameter with the desired precision of the mean is explored. Results led to determine suitable parameters for the different combinations of desired confidence level, precision of the mean and failure criterion. It was also found that when three input variables were involved, or when a three significant digits precision of the mean was required, the number of trials needed to attain convergence was greater than when two inputs variables were involved or when two significant digits precision was required.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"51 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77170338","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}

StorageSim is a process-based discrete-event simulator developed using the SimPy simulation framework. It simulates the operation of a multi-tiered storage system; for example, a system that stores super “hot” files in non-volatile RAM, less “hot” files in solid state drives (SSDs) and “warm” and “cold” files in hard disk drives (HDDs). StorageSim comes with three data-placement policies, and can be extended to support other policies. It can replay publicly available storage traces from the Storage Networking Industry Association (SNIA) and other public sources, and can be used to evaluate data-placement policies prior to implementing them on a real system. By abstracting away many complex details, StorageSim provides a fast simulation framework that can be used to simulate large scale storage systems. Experimental results show that StorageSim is useful, can reproduce prior results from real deployments, and is fast enough to handle Big Data workloads in a timely manner.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"82 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80585313","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 two approaches are introduced aiming at reducing the computational burden in Optimal Placement problems. The goal is to make a preliminary analysis of optimal placement of PMU (OPP) and subsequently to optimize the costs of the communication network (CN) through the minimization of distances of connection between each node. For this purpose, an Integer Linear Programming (ILP) based on algorithm for the PMU placement has been modified and expanded to determine optimal PMU locations by incorporating the effect of zero-injection buses and conventional measurements. In addition, Kruskal's Minimum Spanning Tree algorithm is used to obtain the optimal communication networks with minimum investment. The effectiveness of the proposed method is verified in a real large size transmission system, where geo-referenced data (coordinates) of the buses (nodes) and transmission lines that make up the entire network are obtained. The main objective focuses on minimizing the cost associated with PMU placement and communication network, while ensuring the full observability of the system.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"30 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80769042","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}
