Login Authentication with Facial Gesture Recognition
Facial recognition has proven to be very useful and versatile, from Facebook photo tagging and Snapchat filters to modeling fluid dynamics and designing for augmented reality. However, facial recognition has only been used for user login services in conjunction with expensive and restrictive hardware technologies, such as in smart phone devices like the iPhone x. This project aims to apply machine learning techniques to reliably distinguish user accounts with only common cameras to make facial recognition logins more accessible to website and software developers. To show the feasibility of this idea, we created a web API that recognizes a users face to log them in to their account, and we will create a simple website to test the reliability of our system. In this paper, we discuss our database-centric architecture model, use cases and activity diagrams, technologies we used for the website, API, and machine learning algorithms. We also provide the screenshots of our system, the user manual, and our future plan
Maritime Silk Road and Cultural Exchange and Dissemination of Chinese and Western Artifacts: From the Perspective of Porcelain Trade
Porcelain is the core competitiveness between China and Western trade and representatives of Chinese artifacts. In 16th century the world’s marine trade from the Portuguese made porcelain  become an important link between the East and West culture, in the five hundred years of the sea Silk Road exchange process, porcelain trade promotes the spread of Chinese culture to the world, to build a porcelain culture circle which affects the world. But with the success of European imitation of Chinese porcelain and the development of the industrial revolution, Chinese porcelain which once led the world’s advanced cultural trend faded out of the world trade stage. China, once the porcelain export country, began to import porcelain from Europe and America. Porcelain, which is the representative of Chinese culture, began to be both a reflection of Chinese culture and economy in the context of globalization. It is also an epitome of the awkward position of Chinese artifacts in the process of modernization. Under the Pre-modernization and modernization contexts, porcelain trade embodied the national identity and cultural identity
Chinese Culture Overseas Exchange and Spread Under the Context of Cross-Cultural Perspective
The rapid development of economy and the rise of international politics caused the “China craze” of the international community, and is also an opportunity to spread Chinese culture overseas. Chinese culture has long been in the passive position of “the other construction”, the communication mode will make China lose the ownership of cultural exchange, and then make the culture in the “edge” status. In cross-cultural communication, how to play the government power, through the artifacts, the media and non-governmental organizations to build a complete system of cultural transmission, cultural communication to realize the rationality and validity, give play to its dominant position in Chinese cultural exchange, get the real “image of China” and “voice of China”, is the main direction of the current Chinese culture propagation. Actively integrating into the world culture system, to realize the combination of Chinese culture and the world civilization, not only is the symbol of country cultural confidence and expression, and contribute to world peace and cultural development

Estudio sobre el análisis de errores de la interlengua en la escritura del inglés comercial
[ES] La interlengua es un sistema del lenguaje Ăşnico producido por alumnos que
aprenden una segunda lengua en el proceso de aprendizaje de la lengua meta. Este sistema del lenguaje se encuentra estructuralmente en un estado
intermedio entre el idioma nativo y la lengua meta. La interlengua constituye asĂ
un sistema del lenguaje en continuo desarrollo donde cada alumno está en un
cierto punto de desarrollo del proceso de la interlengua. Con el desarrollo del
aprendizaje, el nivel del idioma de los alumnos se acerca gradualmente a la
lengua meta. Consecuentemente, y debido a las inevitables diferencias entre el
idioma aprendido y el idioma nativo, los alumnos cometen los errores durante el
proceso de aprendizaje del segundo idioma. Cualquier alumno de idiomas debe
pasar por el proceso de aprendizaje de crear la interlengua, desarrollándola y
corrigiendo los errores. En consecuencia, la teorĂa del análisis de errores
basada en la interlengua requiere que los profesores de idiomas extranjeros
analicen los errores en el lenguaje de los alumnos durante el proceso de
aprendizaje de la segunda lengua. Al mismo tiempo, los profesores deben
observar y analizar los errores en la interlengua y comprender las
caracterĂsticas de las etapas de desarrollo en el ámbito del aprendizaje, para
poder enseñar de acuerdo con los conocimientos lingĂĽĂsticos de los alumnos. La teorĂa del análisis de errores es una rama de la lingĂĽĂstica aplicada que
comenzó en la década de 1960 y se desarrolló completamente en la década de
1970. El análisis de errores consiste en un análisis exhaustivo y sistemático de
los errores cometidos por los alumnos en el proceso de aprender idiomas
extranjeros, con el fin de explorar y estudiar la naturaleza y las causas de los
errores, evitando o, en su defecto, reduciendo esos errores. Los errores forman
parte del proceso de aprendizaje y juegan un papel muy importante en la
enseñanza de lenguas extranjeras. Como consecuencia de las investigaciones centradas en este ámbito en China
y en otros paĂses, muchos acadĂ©micos han realizado estudios sobre la enseñanza de lenguas extranjeras basándose en la teorĂa del análisis de
errores de la interlengua, centrándose muchos de estos estudios únicamente
en la enseñanza del inglés general, por lo que pocos académicos han
analizado especĂficamente la enseñanza del inglĂ©s comercial desde el punto de
vista de la interlengua. Por lo tanto, este estudio describe los conceptos y las
investigaciones relacionadas con la interlengua y el análisis de errores, analizando los errores de la escritura en inglés comercial por parte de alumnos
cuya lengua nativa es el chino. El estudio combina la investigaciĂłn cualitativa y
cuantitativa para clasificar y analizar varios errores en la escritura del inglés
comercial, como los errores léxicos, sintácticos y del discurso con el fin de
proporcionar algunas sugerencias pragmáticas para los profesores y los
alumnos de escritura del inglés comercial, pretendiendo con ello mejorar la
enseñanza del mismo en las universidades chinas.[EN] Interlanguage is a unique language system produced by second language
learners in the target language learning process. This language system is
structurally in an intermediate state between the native language and the target
language. The interlanguage thus constitutes a language system in continuous
development where each student is at a certain point of development of the
interlanguage system. With the development of learning, the language level of
the students gradually approaches the target language. Consequently, and due
to the inevitable differences between the target language and the native
language, students make mistakes during the second language learning
process. Any language learner must go through the learning process of creating
interlanguages, developing them and correcting errors. Consequently, the
interlanguage-based theory of error analysis requires foreign language teachers
to analyze students' language errors during the second language learning
process. At the same time, teachers must observe and analyze inter-language
errors and understand the characteristic stages of development in the interlanguage field in order to teach according to the students' basic English ability. Error analysis theory is a branch of applied linguistics that began in the 1960s
and was fully developed in the 1970s. Error analysis is a comprehensive and
systematic analysis of errors made by students in the process to learn foreign
languages, in order to explore and study the nature and causes of language
errors, avoiding or failing to reduce language errors. Mistakes are a process of
learning progress and play a very important role in teaching foreign languages. Throughout the research focused on this field in China and other countries, many scholars have done a lot of research on the teaching of foreign languages
based on the theory of interlanguage error analysis, many of these studies
focusing only on the teaching of English, so few academics have set their sights
on teaching business English. Therefore, this study describes the concepts and
related research of interlanguage and error analysis, analyzing errors in business English writing by business English learners in a native Chinese
environment. The study combines qualitative and quantitative research to
classify and analyze various errors in business English writing, such as lexical, syntactic, and speech errors, to provide some pragmatic suggestions for
business English writing teachers and students, improving the teaching of it in
Chinese universities.Li, S. (2020). Estudio sobre el análisis de errores de la interlengua en la escritura del inglés comercial. http://hdl.handle.net/10251/149340TFG
An Intelligent Fleet Condition-Based Maintenance Decision Making Method Based on Multi-Agent
According to the demand for condition-based maintenance online decision making among a mission oriented fleet, an intelligent maintenance decision making method based on Multi-agent and heuristic rules is proposed. The process of condition-based maintenance within an aircraft fleet (each containing one or more Line Replaceable Modules) based on multiple maintenance thresholds is analyzed. Then the process is abstracted into a Multi-Agent Model, a 2-layer model structure containing host negotiation and independent negotiation is established, and the heuristic rules applied to global and local maintenance decision making is proposed. Based on Contract Net Protocol and the heuristic rules, the maintenance decision making algorithm is put forward. Finally, a fleet consisting of 10 aircrafts on a 3-wave continuous mission is illustrated to verify this method. Simulation results indicate that this method can improve the availability of the fleet, meet mission demands, rationalize the utilization of support resources and provide support for online maintenance decision making among a mission oriented fleet
Mutual Information-Based Integrated Sensing and Communications: A WMMSE Framework
In this letter, a weighted minimum mean square error (WMMSE) empowered
integrated sensing and communication (ISAC) system is investigated. One
transmitting base station and one receiving wireless access point are
considered to serve multiple users a sensing target. Based on the theory of
mutual-information (MI), communication MI and sensing MI rate are utilized as
the performance metrics under the presence of clutters. In particular, we
propose an novel MI-based WMMSE-ISAC method by developing a unique transceiver
design mechanism to maximize the weighted sensing and communication sum-rate of
this system. Such a maximization process is achieved by utilizing the classical
method -- WMMSE, aiming to better manage the effect of sensing clutters and the
interference among users. Numerical results show the effectiveness of our
proposed method, and the performance trade-off between sensing and
communication is also validated
