Mimblewimble is a privacy-oriented cryptocurrency technology which provides security and scalability properties that distinguish it from other protocols of its kind. In previous work we have proposed an idealized model that captures the main features of the Mimblewimble protocol with a model-driven verification approach. In this work, we present an extension of our model to enable zero-knowledge proofs in order to prove that the transaction amount is in a certain range without revealing the value. Furthermore, we provide some security properties a range proof scheme should satisfy.

Renewable variable generation incorporation to the national electric system like wind and solar brought the requirement for more flexibility in the grid. 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.

This work presents a novel methodology for measuring gamma radiation doses, based on an OBIST (Oscillation-Based Built In Self-Testing) scheme. The studied circuit has a configuration of a Colpitts oscillator designed with three nMOS transistors. The gamma radiation incidence on the transistors produces a shift in the threshold voltage, which changes the oscillation frequency and makes it possible to measure the value of the radiation dose.

This paper presents a constructive heuristic algorithm in a multi-start structure applied to planning the expansion of medium voltage overhead distribution lines to supply electricity to current and future customers. This algorithm, through its multi-start feature, establishes a set of viable radial topologies, considering the lowest construction costs, lowest electrical losses, and lowest voltage profiles of a system. 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. The results obtained in the simulations showed that the algorithm finds a set of viable and good-quality solutions.

Human activity recognition aims to infer a person's actions from a set of observations captured by several sensors. 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. The classification algorithm is based on the calculation of statistical features (mean, standard deviation, maximum and minimum) for each accelerometer axis, the application of a dimensionality reduction algorithm (LDA, Linear Discriminant Analysis) and an SVM (Support Vector Machines) classification model.
人类活动识别的目的是从几个传感器捕获的一组观察结果中推断出一个人的行为。边缘设备上的数据采集、处理和推断增加了任务的复杂性，因为它们涉及硬件效率和性能之间的权衡。我们展示了一个可穿戴设备的原型，它可以识别一个人的活动:走路、跑步或静止不动。该系统由一个德州仪器MSP-EXP430G2ET发射台组成，连接到一个带有BMI160加速度计的BOOSTXL-SENSORS增压包。所设计的样机可以进行加速度测量，并对其进行处理，然后将其传输到计算机或在微控制器中对活动进行分类。此外，我们的系统有led根据推断的活动实时显示彩色信号。该分类算法基于计算加速度计各轴的统计特征(均值、标准差、最大值和最小值)，应用降维算法(LDA, Linear Discriminant Analysis)和SVM(支持向量机)分类模型。

In this work we address the optimal operation for an active distribution network that is being used as a benchmark test system. The optimal operation of the active distribution network is divided into two different optimization problems: the Unit Commitment and the Economic Dispatch. The Unit Commitment problem determines the start-up and shut-down schedule of all production units to supply the electric demand minimizing the total operating cost. Then, once the commitment of the generating units is decided, the Economic Dispatch determines, for each hour of the planning horizon, the actual power output of each of the committed generating units necessary to supply the demand and comply with the limits imposed by the transmission network. The optimal operation problem here presented is utilized to analyze two configurations: the first does not include energy storage while the second includes energy storage in two nodes. The results reveal the advantage of using energy storage. As future work, further research will be conducted to include the problem of determining the optimal location and size of storage units.

The insertion of Distributed Generation (DG) represents a great challenge for electric energy concessionaires to develop studies on the control, protection, operation and maintenance of their networks. This topic has been the subject of several studies, which aim to mitigate future impacts on the electric power system. DGs in small quantities play an important role in the energy matrix, improving the voltage levels of the system and being able to solve the cases of undervoltage in the buses identified as critical in the system. Although it in excess can affect the radiality, causing several problems to the network. This article will discuss and present the impacts on protection arising from the insertion of Distributed Photovoltaic Generation in the electrical energy distribution system. The simulations are performed using the IEEE 8500 Nodes Test Case system, through the OpenDSS software controlled by python. The results are presented and evaluated.

Reacting adequately to cybersecurity attacks requires observing the attackers' knowledge, skills, and behaviors to examine their influence over the system and understand the characteristics associated with these attacks. 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.

This work presents and validates an intra-day operational solar forecast for the southern cone of South America based on GOES16 satellite images. The forecast is evaluated over 12 photovoltaic (PV) generation sites in the northwest of Uruguay. The irradiance predictions are obtained from the combination of different satellite cloudiness forecasts and a standard satellite-to-irradiance conversion model, both specifically adapted to the region. 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. The performance assessment of the individual sub-forecasts and their combination is presented for each time horizon between 10 minutes and 4 hours, with a 10 minutes time step.
