In this article we provide a general framework using Ethereum smart contracts to track back the provenance and evolution of deep learning content (DLC) to its original source even if the DLC was edited (e.g. DL models were retrained or/and datasets were updated) by anonymous authors. The main principle behind the solution is that if the DLC can be credibly traced to a trusted or reputable source, the DLC can then be real and authentic. The solution is proposed in the healthcare context and for medical DLC, especially for federated machine learning, but it can be applied to any other form of DLC.
在本文中,我们提供了一个通用框架,使用以太坊智能合约来追溯深度学习内容(DLC)的来源和演变,即使DLC被匿名作者编辑(例如DL模型被重新训练或/和数据集被更新)。解决方案背后的主要原则是,如果DLC可以可信地追溯到可信或有信誉的来源,那么DLC就可以是真实的和真实的。该解决方案是在医疗保健上下文中提出的,适用于医疗DLC,特别是联邦机器学习,但它可以应用于任何其他形式的DLC。

It is a difficult problem in the field of computer science to be able to answer the question of what configuration parameters will be used to generate long bit strings with linear feedback shift register structures, which is a component widely used in many practical applications that require random behavior. Since this difficult challenge is a problem with NP computational complexity, the difficulty of developing solutions in classical ways has been tried to be solved by using optimization algorithms. In this study, all possible configurations that can be used for all linear feedback shift register structures up to eight degrees have been determined using the binary bat optimization algorithm. Statistical properties of random sequences generated using these configurations have been tested using the chi-square test. All the resulting configurations are shared as a public dataset. It is thought that these successful results can be used effectively in various practical applications by many researchers in the future.

The newly detected virus also called coronavirus spreads the disease Covid19. World Health Organization (WHO) confirmed this virus as a worldwide pandemic as it has infected millions of people and has taken away many lives across the globe. An infection caused by Covid19 disease majorly destroys the respiratory tract of human beings that ends with multiple organ failures or death in the worst case. In the present work, chest radiographs were provided as input to various deep learning CNN architectures for the purpose of feature extraction. After extracting the features, the images were provided as the input to various machine learning classifiers that classify the chest radiographs as Covid-19 positive, pneumonia infection, or healthy scans.

The cryptology science has gradually gained importance with our digitalized lives. Ensuring the security of data transmitted, processed and stored across digital channels is a major challenge. One of the frequently used components in cryptographic algorithms to ensure security is substitution-box structures. Random selection-based substitution-box structures have become increasingly important lately, especially because of their advantages to prevent side channel attacks. However, the low nonlinearity value of these designs is a problem. In this study, a dataset consisting of twenty different substitution-box structures have been publicly presented to the researchers. The fact that the proposed dataset has high nonlinearity values will allow it to be used in many practical applications in the future studies. The proposed dataset provides a contribution to the literature as it can be used both as an input dataset for the new post-processing algorithm and as a countermeasure to prevent the success of side-channel analyzes.
随着我们的数字化生活,密码学逐渐变得重要起来。确保跨数字通道传输、处理和存储数据的安全性是一项重大挑战。替换盒结构是加密算法中常用的保证安全性的组件之一。基于随机选择的替换盒结构近年来变得越来越重要,特别是因为它们在防止侧信道攻击方面的优势。然而,这些设计的低非线性值是一个问题。在这项研究中,一个由20种不同的替代盒结构组成的数据集已经公开呈现给研究人员。所提出的数据集具有高非线性值的事实将使其在未来的研究中用于许多实际应用。所提出的数据集为文献提供了贡献,因为它既可以用作新的后处理算法的输入数据集,也可以用作防止侧信道分析成功的对策。

Sentiment analysis is one of the significant tasks in processing natural language by a machine. However, it is difficult for a machine to understand the feelings of a person and opinion about a topic. Many approaches have been introduced for analyzing sentiment from long text in recent past. In contrast, these approaches fail to address the small length text problem like Twitter data efficiently. Recent advances in the pre-trained contextualized embeddings like Bidirectional Encoder Representations from Transformers (BERT) show far greater accuracy than traditional embeddings. In this paper, we develop a novel architecture to tune the BERT using a Bidirectional Long Short-Term Memory (Bi-LSTM) model. A task-specific layer is incorporated along with the BERT in the proposed model. Our model extracts sentiment from short texts, especially Twitter data. The extensive experiments show the superiority of our model over state-of-the-art models in sentiment analysis task across several gold standard datasets.
情感分析是机器处理自然语言的重要任务之一。然而,机器很难理解一个人的感受和对一个话题的看法。近年来,人们提出了许多方法来分析长文本的情感。相比之下,这些方法不能有效地解决像Twitter数据这样的小长度文本问题。最近在预训练情境化嵌入方面的进展,如变形金刚的双向编码器表示(BERT),显示出比传统嵌入更高的准确性。在本文中,我们开发了一种使用双向长短期记忆(Bi-LSTM)模型来调整BERT的新架构。在提议的模型中,与BERT一起合并了一个特定于任务的层。我们的模型从短文本中提取情感,尤其是Twitter数据。广泛的实验表明,我们的模型在多个金标准数据集的情感分析任务中优于最先进的模型。

Local energy trading is a concept that allows trading between distribution grid participants such as consumers, producers, and prosumers on a local level in a transparent and competitive way. This can provide better local demand-supply balancing, decrease voltage deviations, and improve social welfare. However, economic feasibility of implementation of such a concept greatly depends on regulatory framework, as certain regulatory provisions can either lead to barriers and costs that can undermine the potential benefits of local energy trading, or support implementation of such projects. In this paper, feasibility of local energy trading under different variations of regulatory framework are assessed and implications on market participants and energy balance in distribution grids analyzed. It is shown that regulatory provisions have high influence on potential benefits and implementation of local energy trading in wider scope.
本地能源交易是一个概念,它允许配电网络参与者(如消费者、生产者和产消者)在本地以透明和竞争的方式进行交易。这可以提供更好的本地供需平衡,减少电压偏差,提高社会福利。然而,实施这一概念的经济可行性在很大程度上取决于监管框架,因为某些监管规定可能导致障碍和成本,从而破坏当地能源交易的潜在利益,或支持此类项目的实施。本文评估了不同监管框架下地方能源交易的可行性,并分析了对市场参与者和配电网能源平衡的影响。研究表明,在更大范围内,监管规定对地方能源交易的潜在效益和实施有很大影响。

Based on Maxwell’s equations, the dependences of the total and active resistance of the electrical network on the frequency of the flowing current are determined, which allows to determine the additional power losses due to higher harmonics of higher harmonics. The analysis of convergence of the received equations with expressions of the international standard IEC 60287-1-1 is resulted. It is shown that for the high frequency zone the expressions of the IEC 60287-1-1 standard describing the dependence of the active resistance on the frequency give a significant error. A simplified approximation dependence is proposed for the high-frequency zone, which makes it possible to determine the dependence of the active resistance on the frequency without the use of Bessel equations. The obtained equations can be used to determine additional power losses in the active supports of electrical networks, windings of electric machines, high-frequency transformers from higher harmonics of currents at different nonlinear loads. In addition, the obtained expressions can be used to justify the use of filter-compensating devices.
根据麦克斯韦方程组,确定了电网总电阻和有源电阻对流动电流频率的依赖关系,从而可以确定由于高次谐波的高次谐波而造成的额外功率损失。用国际标准iec60287-1-1的表达式分析了接收方程的收敛性。结果表明,在高频区,IEC 60287-1-1标准中描述有源电阻随频率变化关系的表达式存在显著误差。提出了一种简化的高频区近似依赖关系,使得在不使用贝塞尔方程的情况下确定有源电阻对频率的依赖关系成为可能。所得方程可用于确定不同非线性负载下高次谐波电流对电网有源支撑、电机绕组、高频变压器的附加功率损耗。此外,所得到的表达式可以用来证明使用滤波器补偿装置的合理性。
