Adults spend 80% of their time indoors every day, so the quality indoor air is closely related to people's health and life.In this project, an environment monitoring system designed for quality. Data interaction between carried out by means wireless transmission, as monitor PM2.5 concentration, temperature humidity in real through mobile phones.Realization function: For collection various param...

This paper asks how rhythmicity is used to manage speaker transition in spontaneous talk and how temporal alignment helps to achieve interactional alignment. 56 Question + Answer (Q+A) pairs were analysed. 44 (79%) Qs ended rhythmically: in their last few accented syllables, f0 prominences were quasi-periodic. Of the As to these rhythmic Qs, 32 (73%) began with the same periodicity as the Q. As...

The literature so far has analyzed the effects of Minimum Quality Standards in oligopoly, using models of pure vertical differentiation, with only two firms, and perfect information. We analyze products that are differentiated horizontally and vertically, with imperfect consumers information, and more than two firms. We show that a MQS changes the consumers’ perception of produced qualities. Th...

This paper proposed an intelligent wireless indoor monitoring system based on STM32F103. The system compromises a master and terminals, which communicates through a CC1101 433M wireless unit. Using ENC28J60 and SIM900A to access Ethernet, the system can intelligent push information to cloud server, therefore we can observe and control terminals remotely. This paper present an algorithm based on...

Traditional university instructional formats and methods are experimenting an increasing lack of effectiveness, mainly because student's lack of motivation. The NUCLEO e-learning system tries to approach the learning scenario to the engaging and immersive formats of the videogames. It provides a futurist scenario in which students (represented by avatars) have to collaborate to solve a learning...
