Storage technologies can contribute to it, being pumped storage the most used globally for this purpose. While traditional pumped storage trend to be more feasible at larger scales (above 250 MW), Uruguayan power system appears to need only between 10 and 30 MW to balance variable generation. Small turbines could be used for this purpose but their high price makes it many times prohibitive. Using a pump in reverse rotation, acting as a turbine generating electricity, could be a more economical alternative in order to filter generation peaks and demand fluctuations. Remarkably, any kind of pump “off the shelve” can be used as a turbine. Performance remains almost same as in pump mode, and it can be improved with small modifications such as blade tip rounding, or replacing intake for a specially deigned square section diffuser.","PeriodicalId":337257,"journal":{"name":"2021 IEEE URUCON","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129542226","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 core of the system is a Cloud Motion Vector (CMV) satellite technique, considered in different spatial resolutions. The optimal linear combination of a single-pixel and space-averaged CMV forecast with the space-averaged persistence is proposed and analyzed.

We differentiate between private cars, taxis, and digital platforms. With the Levelized Cost of Charging (LCOC), we captured the variations related to charging sites, types of equipment, cost, and time of charging. We investigated the LCOC for residential and work/public charging sites and an average LCOC for chargeable EV, which represents the current charging patterns. We also performed a sensitivity analysis for a deeper understanding of the factors that drive the LCOC and how much the cost of charging an EV affects in Uruguay. Furthermore, this indicator was used to calculate the lifetime fuel cost of charging, which measures the total fuel saving of an EV compared with an Internal Combustion Engine Vehicle (ICEV) under similar conditions. In order to make these comparisons, we made several assumptions regarding the future oil prices, charging behaviors, types of equipment costs, and vehicle use (VMT). Finally, we compared the LCOC found for Uruguay with the LCOC for the United States.","PeriodicalId":337257,"journal":{"name":"2021 IEEE URUCON","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122469297","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}

Profiling an attacker allows generating security countermeasures that can be adopted even from the design of the systems. For automated attackers, e.g., malware, it is possible to identify structured behavior, i.e., a process-like behavior consisting of several (partial) ordered activities. Process Mining (PM) is a discipline from the organizational context that focuses on analyzing the event logs associated with executing the system's processes to discover many aspects of process behavior. Few proposals are applying PM to attacker profiling. In this work, we explore the use of PM techniques to identify the behavior of cyber attackers. In particular, we illustrate, using an application example, how they can be adapted to an environment dominated by automated attackers. We discuss preliminary results and provide guidelines for future work.","PeriodicalId":337257,"journal":{"name":"2021 IEEE URUCON","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127241387","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 acquisition, processing and inference on edge devices add a complexity factor to the task, as they involve a trade-off between hardware efficiency and performance. We present a prototype of a wearable device that identifies a person's activity: walking, running or staying still. The system consists of a Texas Instruments MSP-EXP430G2ET launchpad, connected to a BOOSTXL-SENSORS boosterpack with a BMI160 accelerometer. The designed prototype can take acceleration measurements, process them and either transmit them to a computer or classify the activity in the microcontroller. Additionally, our system has LEDs to display coloured signals according to the inferred activity in real-time.

For this process, the algorithm considers normalized weights and random numbers aiming at a larger search field for a solution. The problem is represented by a nonlinear mathematical model and the solution is constructively obtained in an iterative way. At each iteration, a sensitivity indicator is used to decide which circuit to build. Computational tests were performed to evaluate the algorithm's performance.
