The proposed approach relies on the data coming from CO2 concentration sensor, door contact, window con- tact, occupancy labels extracted from video cameras for tuning air flows,

Thus unlike mixed representations as metric-topologic ones, we propose a new unified framework for multi-resolution map building based on wavelets, which we call the wavelet

The subsystem utilized for the occupancy extraction is constituted by a collection of depth image cameras and a multi-sensorial cloud (various types of simple sensors) in order

Abstract. Recent information systems have become large and complex by interacting with each other via networks. This makes assuring de- pendability of systems much more difficult

On s’intéresse à l’étude de ces équations le cas où les coefficients ne vérifient pas la condition de Lipschits ; précisément dans le cas où les coefficients sont

First-principles density functional full potential calcula- tion of absolute position of valence and conduction energy band edges as a function of 共001兲 biaxial strain were carried

In addition to its own portfolio of office buildings, shopping centers, retirement lodges, nursing homes, and hotels, the company also has major equity interests

Parameters such as reaction time and formaldehyde-to-phenol sources (phenol + lignin) mass ratios were optimized to achieve the requirements for industrial wood adhesives
