Recently, pre-trained language representation models such as BERT and RoBERTa have achieved significant results in a wide range of natural language processing (NLP) tasks, however, it requires extremely high computational cost. Curriculum Learning (C L) is one of the potential solutions to alleviate this problem. CL is a training strategy where training samples are given to models in a meaningful order instead of random sampling. In this work, we propose a new CL method which gradually increases the block-size of input text for training the self-attention mechanism of BERT and its variants using the maximum available batch-size. Experiments in low-resource settings show that our approach outperforms the baseline in terms of convergence speed and final performance on downstream tasks.
This paper is devoted to the analysis of the impact of chaos-based techniques on block encryption ciphers. We present several chaos based ciphers. Using the well-known principles in the cryptanalysis we show that these ciphers do not behave worse than the standard ones, opening in this way a novel approach to the design of block encryption ciphers.
This paper presents a new type of encryption, using a matrix asymmetric and symmetric matrix inverse matrix clear text, which is an internal encryption. As well as asymmetric encryption, where the ciphertext is inversely symmetric matrix. Decryp tion matrix related to any asymmetric encryption keys depends on public and private, and is applied to the coded messages used in the current system ASCII our computers.
Wireless Multimedia Sensor Network (WMSN) consists of a large number of small size, low power, limited sources sensor nodes, deployed in tested field, These nodes have the ability of sensing, processing, storing and sending multimedia data from the t ested field in real time. The security in WMSNs is one of most important issues that should be studied due to the special nature of this network, and of the importance of inquest basic security requirements when sending information in the network. Using cryptography technics are very effective ways to realize basic security requirements in this network. The recently proposed MQQ algorithm is one of public key cryptography (PKC) algorithms, which provides a good performance compared to other PKC algorithms. In this research, we present an analyzing study of MQQ implementation in WMSNs. To achieve our goal, we used real images taken by multimedia wireless sensor nodes. We studied the most important parameters such as the size of generated keys and encrypted images, the execution time and the space occupied in the flash memory of multimedia wireless sensor nodes and complexity degree of this algorithm. Results showed that MQQ has good performance, as well as the execution time of operations is better than RSA algorithm. Results also showed the importance of taking into account a large size of public key of MQQ algorithm when implementation it in WMSNs.
Solar Energy and Hydrogen are possible replacement options for fossil fuel, But a major drawback to the full implementation of solar energy, in particular photovoltaic (PV), is the lowering of conversion efficiency of PV cells due to elevated cell t emperatures while in operation. Also, hydrogen must be produced in gaseous or liquid form before it can be used as fuel; but its‟ present major conversion process produces an abundance of carbon dioxide which is harming the environment through global warming. In search of resolutions to these issues, this research investigated the application of Thermal Management to Photovoltaic (PV) modules in an attempt to reverse the effects of elevated cell temperature. The investigation also examined the effects of the thermally managed PV module to a Electrolyzer (Hydrogen Generator) for the production of hydrogen gas in an environmentally friendly way. The results of the investigation showed that the cooling system stopped the cell temperature from rising, reversed the negative effects on conversion efficiency, and increased the power output of the module by as much as 33%. The results also showed that the thermally managed PV module when coupled to the hydrogen generator impacted positively with an appreciablely increase of up to 26% in hydrogen gas production.
