In this paper, we look at a database of tweets sorted by various keywords that could indicate the users’ sentiment towards covid vaccines. With social media becoming such a prevalent source of opinion, sorting and ranking tweets that hold important information such as opinions on covid vaccines is of utmost importance. Two different ranking scales were used, and ranking a tweet in this way could represent the difference between an opinion being lost and an opinion being featured on the site, which affects the decisions and behavior of people, and why researchers were interested in it. Using natural language processing techniques, our aim is to determine and categorize opinions about covid vaccines with the highest accuracy possible.

This paper examines the performance of a specific Long-Short Term Memory Recurrent Neural Network for cursive handwriting generation when training with small datasets. The RNN can generate complex structure sequences by predicting one data point at a time. Then, by predicting the overall writing structure, the handwriting can be synthesized. The resulting network can generate different handwriting style parameters.

The interactive experience of virtual scenes is a computer-generated virtual scene. This virtual scene allows users to temporarily detach from reality, immerse themselves in it and interact with the objects in the scene. This is conducive to mobilizing the user's enthusiasm to use, while adding a touch of comfort to the traveler in the tired journey, will experience a different fun from the real life. At the same times, this scenario will also allow the user to experience it in a way that will also inspire or connect with the mind. The two scenes selected for this project are "porthole" and "listening, moving in the sky". The first scene does not change the interaction between the user and the screen, and enables the user to experience the scenic spots of chinese distinctive cultural heritage and traditional culture, and in the age of the internet, it reflects chinese friendliness to people all over the world, and at the same time better spreads and protects chinese traditional culture. The second landscape allows children to experience the feeling of stepping into the sky in the game, reducing the anxiety brought to children by long waiting time, and the interaction of the connection between the speaker and the horn can effectively promote the communication between children.

"The Belt and Road Initiative " (B&R) is the abbreviation of the "Silk Road Economic Belt" and the "twenty-first Century Maritime Silk Road". In September and October of 2013, which is proposed by Chinese President Xi Jinping when he visiting Central Asia and Southeast Asia. With the acceleration of social development, people's demand for fast-paced affairs is higher and higher. The traditional way of presentation has been unable to full the needs of users, while the use of mobile phones, computers and other electronic terminals is rising, which promotes the rapid development of virtual reality technology and the possibility of transmission. This system takes “The Belt and Road Initiative” as the background, and takes the "road trip" as the theme. Through the planning and design of virtual technology exhibition hall and the reduction of scenes, the platform is built using C4D, 3Dsmax and other platforms. Using PS, PR and other platforms to complete the production of material mapping and display video; Using the UE4 as the main technology development platform, it will show one's "The Belt and Road Initiative " style to the experiencer.

In a web-based Augmented Reality (AR) application, to achieve an immersive experience we require precise object detection, realistic model rendering, smooth occlusion, and accurate augmentation in real-time. To achieve these objectives on a device requires heavy computation capabilities unavailable on most mobile devices, this can be solved by using cloud computing but it introduces network latency issues. In this work, we propose a new network protocol named DLDAR (Dynamic Load Distribution in web-based AR) that facilitates and standardizes methods for dynamic division of compute between client and server for achieving real-time performance in a comprehensive AR web application. The protocol will manage computation and network latency by dynamically provisioning compute between client and server based on device and network condition to min-max latency and quality. We demonstrate our approach by developing a web application that enables users to celebrate the regional festival “Raksha Bandan” by sharing wristbands “rakhis” that can be augmented on your wrist. This protocol can be used to create complex web AR applications with more realistic rendering, animations, and interactive environments.

Since the ability of convolution Neural Networks (CNN) on image classification has been discovered by research workers. Many studies revealed using CNN on image classification can make a breakthrough continuously. The CNN can be used for many different researches. However, there is less study using CNN to classify or recognize the sweetness of the fruit. Therefore, this paper will use CNN model to develop a non-invasive classifier for the sweetness levels of the apples that are sweet, normal and not sweet. The researchers of this paper collected a total of 130 apples to generate the dataset. There are 130 average sweetness data of the apples and 1506 apples appearance images in the dataset. Also, five different parameter settings were used to train AlexNet. The results of training were compared and validated between each setting. The best experience result of training and validation accuracy comes to 99.86% and 81.00% separately in this paper. As a consequence, the result revealed CNN has ability on fruit sweetness classification.

The failure of machines at oil and gas platforms that will temporarily stop oil production commonly happens. The failure may refer to the machine that has stopped working, is not working properly, or does not meet target expectations. In this research, we are assessing the state of the condition of a turbine generator. A turbine generator is a connection of a shaft of a steam turbine or gas turbine engine connected to a high-speed electric generator to generate electricity in the process of drilling and digging. Machine failure will cause loss to the oil and gas industry due to the interruption of oil production. Hence, the purpose of this study is to predict machine failure using linear regression on KNIME platform. By predicting machine time-to-failure using machine learning, maintenance can be scheduled and performed before failure occurs. Upon measuring the accuracy of the predicted model, the result will be visualized through a dashboard for user monitoring.
