To achieve the most understandable and accurate display of information, a study on the available techniques of data visualization for real-time information must be made. Customizing existing platforms and designing specific boards, are among the important task to perform an accurate visualization of the information. In this paper, we conduct a literature review of data visualization, its techniques and existing dashboard platforms. We implemented a generic and dynamic dashboard based on real-time information with the aim to assess the impact of the available Data Visualization Techniques in the developed dashboard. Therefore, our Dashboard users will be able to interact with the information, based on an initial set of hints, charts, tables and reports, produced by the Dashboard itself. This will allow us to test an existing set of data visualization techniques and create a new tailored dashboard, showing that dashboards can become a unique and powerful means to provide information.
Significant innovation has been made in the development of public-key cryptography that is able to withstand quantum attacks, known as post-quantum cryptography (PQC). This paper focuses on the development of an efficient PQC hardware implementation. Specifically, an implementation of the binary Ring-learning-with-errors (BRLWE)-based encryption scheme, a promising lightweight PQC suitable for resource-constrained applications, is proposed. The paper first develops the mathematical formulation to present the proposed algorithmic process. The corresponding hardware accelerators are then described in detail. Finally, comparisons with previous implementations are provided to demonstrate the superior performance of the proposed design. For instance, the proposed low-complexity accelerator has 34.7% less area-delay product (ADP) than the state-of-the-art design for n ¼ 256 in the field-programmable gate array (FPGA) platform. Apart from the efficiency of the hardware architectures, the proposed design also has a complete input/output processing setup, and thus is feasible for emerging lightweight applications.
In this paper has been evaluated the transient response of Dynamic Voltage Restorer (DVR) against voltage sags and the impact of these electronic devices to maintain the continuity of supply of wind farms against a three-phase voltage sag. The aim of these studies is to verify the influence of the DVR on the ability of wind turbines and wind farms to fulfill the more demanding grid connection requirements of power systems operators. Moreover, the simulations are performed in order to: Analyse the impact of DVR device on the transient response of wind farm. Evaluate the capacity of fixed speed wind farms to maintain the continuity of supply during three-phase voltage sags.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
