Capturing psychological changes and aspirations of the young, especially students, is always the essential concerns. However, this is still a big challenge not only for administrators but also for psychologists. Due to the population of sharing inside feeling trends through confessions in student communities, confession pages become a valuable source for identifying the interests and attitudes of communities. In our research, we propose a confession pages mining methodology based on text analysis method. This method is applied to several confession pages of student communities in a year to find out interest issues and their attitude. As a result, the model achieved average accuracy as F-measure = 62.45% for interest issues classification and Fmeasure = 76.43% for sentiment classification. The model have been applied to mining characteristics of community of four universities.

One of the very important activities in underground mining is ventilation, because air has to be supplied in most of the cases that is fresh and clean for the tasks in which they are in operation, taking into account the conditions that the product already has of the previous activities, such as: implementation of alternative methods such as the use of fans, extractors or work for ventilation purposes in order to achieve an adequate, healthy and comfortable environment for all employees who are in the mine;is that constant improvements are made to the "ventilation system." That is why this article aims to simulate a new ventilation system that enhances the current ventilation system of the "Uchucchacua" mine of the Buenaventura company located in the province of OyonLima, taking into account, that sufficient air flow must be guaranteed for persons and equipment authorized to work on a watch.

The nascent field of Public-Private Partnerships (PPPs) in energy has been promoted in recent years as a collective response to the urgent need to shift towards clean and sustainable energy systems. However, the evolution of this domain is limited by the absence of a clear structure and strong connecting elements. By shedding some light on this topic, our research seeks to use intelligent data analytics and computational visualization in co-citation analysis to identify relevant research streams and collaborative networks. The findings reveal current clusters and research strands formed by scholars form based on their co-citation links. The study contributes to the growing body of knowledge in the field via a better understanding of PPPs in energy for its further development.

A gaze based interface was used as the basis for a interaction system supporting a remote operator of a ground reconnaissance robot when classifying objects previously identified by a software. Using the gaze point as a cursor, a pre-selection of the object in the sightline is made, allowing the user to effect the symbol via a haptic interface. An extension of the system enables the user to manually re-adjust the pre-selection if highlights are overlapping. The results from a first exploration were encouraging;the system was easily understood and used but does require further testing with scenarios that are more complex.

A humanoid robot and a virtual human with human-like appearance were developed, and various similar intelligence, functions, autonomy and interaction modalities were developed for them that were deemed necessary for their real-world collaboration. The virtual human was integrated with the robot through a common platform based on some control algorithms so that they were capable of cooperating with each other in a real-world task, which was the task of assisting each other in searching for a hidden object in a homely environment. One important activity for such dynamic collaboration was the virtual human's ability to predict the robot's intention so that the virtual human could plan to collaborate with the robot, and vice versa. To address this problem, three representative robot behaviors such as hand shaking, hand pointing and hand waving were analyzed using supervised learning-based algorithms associated with image processing to help the virtual human learn robot behaviors so that the learned behaviors could help the virtual human predict the robot's intention during their intended social interactions. In the training phase, the robot showed each of the three behaviors separately for 500 times. Images of each type of behaviors were taken separately, and the properties of the images were extracted following the image processing method. Then, each robot behavior extracted through image processing was labeled properly. Then, the supervised learning algorithm was developed that classified three different robot behaviors into three different classes. In the testing phase, the robot showed each of its three behaviors to the virtual human randomly for 100 times, the images were taken in real-time, and sent to the image processing-based machine learning algorithm. It was monitored whether the virtual human was able to recognize the robot behavior properly. The results showed that the virtual human was able to recognize robot behaviors and thus predict the robot's intentio
