Authors: Amina Ibrahim k. , Bayda Atiya Kalaf
Published: May 2021

Estimation of the parameters is quite important in the numerous fields for the development of mathematical models. Maximum likelihood estimation is a good method, which is usually used to elaborate on the parameter estimation. The likelihood function formed for the parameter estimation of Log-Logistic is very hard to maximize. Therefore, this paper proposes a new hybrid of Maximum Likelihood Estimator (MLE) and Simplex Downhill Algorithm (SDA) called (MLESDA) to estimate parameters of Log-Logistic distribution based on Survival functions. To compare the suggested method (MLESDA) and classical Maximum Likelihood (MLE) method, simulation is used. The results demonstrate that MLESDA is more efficient than the MLE method.

Published: May 2021

In this paper, we study and investigate a simple donor-acceptor model for charge transfer formation using a quantum transition theory. The transfer parameters which enhanced the charge transfer and the rate of the charge transfer have been calculated. Then, we study the net charge transfer through interface of Cu/F8 contact devices and evaluate all transfer coefficients. The charge transfer rate of transfer processes is found to be dominated in the low orientation free energy and increased a little in decreased potential at interface comparison to the high potential at interface. The increased transition energy results in increasing the orientation of Cu to F8. The transfer in the system was more active when the system has large driving force energy and caused fast transfer from the donor to the acceptor and the charge transfer rate dependent on potential and solvents effect.

Authors: An Kun
Published: May 2021

artificial intelligence (AI), abbreviated in English, is the research and development of human body to produce new technologies to simulate and expand the application of human intelligence in machines. The ultimate goal of artificial intelligence is to be able to produce robots that are not different from human beings and only listen to human beings. To achieve this technology, the most important thing is to be able to analyze and study the substantive operation function of human intelligence. The most ideal way of language learning is to be able to personally visit the language environment, feel the atmosphere of the language culture, and have in-depth communication with the language owner. However, in reality, such an idealized state is impossible to exist, so literary works have become more ideal language and cultural materials. Both British and American languages use English to communicate, although both belong to English, the cultural differences lead to their different ways of expression. This paper first makes a simple analysis of the artificial intelligence system, then analyzes the differences between British and American literary works, and then interprets and analyzes the application of artificial intelligence system in British and American literary works in detail.

Authors: Xiao Chengxiao
Published: May 2021

With the improvement of computer processing ability, we have been able to apply a variety of algorithms to deal with problems in life. Traditional translation is a kind of artificial translation or cat translation, which is a simple translation of vocabulary and grammar. With the deepening of international trade, traditional translation can’t meet the needs of people, which needs to improve the level of human-computer translation. With the rapid development of machine learning, neural network algorithm and deep learning algorithm have been gradually applied to machine translation, which has made machines process text, language and other information like human beings. In recent years, neural network algorithm has brought a broader prospect to natural language processing, which can deal with text semantics more naturally. Traditional translation is difficult to process information semantically, which is a way of relying on artificial information. With the implementation of neural network algorithm, human-computer translation system can improve the speed of language translation, which can better improve the ability of autonomous learning. Firstly, this paper analyzes the related concepts. Then, this paper analyzes some neural network algorithms.
