Real-time monitoring solution with vibration analysis for industry 4.0 ventilation systems

Integrated active sensor system for real time vibration monitoring

We report a self-powered, lightweight and cost-effective active sensor system for vibration monitoring with multiplexed operation based on contact electrification between sensor and detected objects. The as-fabricated sensor matrix is capable of monitoring and mapping the vibration state of large amounts of units. The monitoring contents include: on-off state, vibration frequency and vibration ...

A CLOSED FORM SOLUTION FOR FREE VIBRATION ANALYSIS OF TUBE-IN-TUBE SYSTEMS IN TALL BUILDINGS

In this paper the dynamic response of tube-in-tube systems for tall building structures is investigated. Inner and outer tubes are modeled using equivalent continuous orthotropic membranes; in which, each tube is individually modeled by a cantilever box beam. By applying the compatibility conditions on deformation of the two tubes, the governing dynamic equations of the tube-in-tube structure a...

Runtime monitoring for open real- time systems

Run-time monitoring of real-time systems

This paper presents a model and an implementation of a run-time environment for specifying and monitoringproperties of real-time systems. Theproposed approach supports annotating real-time programs with events that are recorded and examined at run-time. It provides two general methods for synchronous or asynchronous monitoring o f realtime constraints. In the synchronous case, a system constrai...

Cooperation with Industry in Real-time Systems at Crim

Given the increasing pressures on the private sector to be competitive in the world marketplace , governments , industry, and universities have come to understand the importance of encouraging technology development within the framework of technology transfer. The Computer (science) Research Institute of Montreal (CRIM) or in French, le Centre de recherche informa-tique de Montreal, was created...
