BECDS: a secure blockchain-based electricity customer data storagescheme for smart grid

As the power consumption increases year by year, the traditional power network can no longer meet the new demands of power grid development. In this context, smart grid is proposed as the next-generation grid development direction. However, the informationization of power grid will certainly bring the explosive growth of customers' power consumption data, which brings challenges to the security and management of power data. Blockchain, as a distributed cryptographic ledger, is considered as a powerful tool to ensure data security. This paper first analyses the current risks and problems of electricity customers data security in smart grids and proposes to solve them with blockchain. Then, this paper proposes a secure blockchain-based electricity customers data storage scheme (BECDS) and gives its framework. Finally, this paper uses cryptographic vector commitment to construct a distributed and verifiable data storage scheme based on blockchain, and proves that the scheme proposed in this paper is secure in the scheme evaluation.

SELECTION OF THE BEST B-SPLINE REGRESSION MODEL FOR ESTIMATING BITCOIN PRICE INCREASES BASED ON ORDER AND OPTIMAL KNOT POINT

The cryptographic virtual currency, bitcoin, is considered the main originator of cryptocurrencies that emerged due United States financial crisis in 2008. The idea was sparked by Nakamoto by introducing an alternative currency system that really refers to the strength of supply and demand. Based on INDODAX data, the bitcoin exchange rate during October 2020 to February 2021 is a condition of a large increase in a short time with a percentage increase of 450%. The increase in bitcoin prices can be modelled using the b-spline nonparametric regression method based on order and optimal knot points based on the smallest Generalized Cross Validation value. The resulting b-spline 4 degree and the number of knots points 5 as the best model with each bases described recursively.
Determining The Optimal Portfolio Markowitz Model on Moving Stock Prices Using Brown Motion Geometry

Stock price movements that fluctuate and follow a stochastic process will make it difficult for investors to start investing. For that, we need a stochastic mathematical model. The Brownian geometry motion model is one of the stochastic models that can be used to display the condition of a stock's price movement. Investment is related to the rate of return (return) and the risk obtained. The higher the rate of return obtained, the higher the risk obtained. Therefore, a portfolio calculation is needed, one of which is using the Markowitz model. The Markowitz model can be used to determine the optimal portfolio. The purpose of this study is to model stock prices and form an optimal portfolio. The stock price data used are BBRI, TLKM, and ADRO for the period from 1 July 2021 to 31 August 2022. The results obtained from this study are that there are three portfolio preferences. If investors like high risk to get high returns, then the combined allocation of funds for BBRI, TLKM and ADRO shares is 10.51%, 42.05% and 47.44% respectively. If investors do not like high risk but still want to get a return that is balanced with risk, then the combination of fund allocation for shares of BBRI, TLKM and ADRO is 22.62%, 46.63% and 30.75%, respectively. If the investor chooses minimum risk, the combined allocation of BBRI, TLKM and ADRO shares is 34.73%, 51.21% and 14.06%, respectively.
The evaluation of university management performance using the CS-RBM algorithm

Amidst the ongoing higher education reforms in China, the escalated investments in colleges and universities underscore the need for an effective assessment of their performance to ensure sustainable development. However, traditional evaluation methods have proven time-consuming and labor-intensive. In response, a novel approach called CS-RBM (Crow Search Restricted Boltzmann Machine) prediction algorithm has been proposed for the educational management of these institutions. By integrating the CS algorithm and an enhanced RBM algorithm, this method facilitates the scoring of project performance indicators, bolstered by insights from user evaluation form reports. The comprehensive project performance is ultimately derived from this combination. Comparative analysis with the standard particle swarm optimization algorithm on public data sets demonstrates a remarkable 45.6% reduction in prediction errors and an impressive 34.7% increase in iteration speed using the CS-RBM algorithm. The accuracy of the tested data set surpasses 98%, validating the efficacy of the CS-RBM algorithm in achieving precise predictions and effective assessments. Consequently, this innovative approach exhibits promising potential for expediting and enhancing the performance evaluation of colleges and universities, contributing significantly to their sustainable development.

CIRef: A Tool for Visualizing the Historical Data of Software Refactorings in Java Projects

Context: Refactorings are actions developers do not often do in a standard way. One of the reasons is the lack of visualizations in current tools capable of identifying refactorings. Code visualizations can help developers make decisions about analyzing code quality and possible code refactorings. Objective: We present CIRef, a tool for visualizing the historical data of refactorings in Java projects. For a particular project, CIRef provides a wide range of visualizations including customizable rankings of the importance of different refactoring types, duels between developers to understand their profiles, and a timeline of the number of refactorings performed. Method: To validate the acceptance and perceived usefulness of CIRef, we conducted a study with eight developers using the Technology Acceptance Model (TAM). Results: The results indicate that 75% of the participants agreed with using the tool in the future and found it easy to use. Conclusions: Beyond supporting developers in visualizing historical refactoring data, CIRef also has the potential for educational purposes. It can help teachers visualize the history of refactorings performed by students, especially in educational environments focused on programming and maintaining Java projects.
