Le Cirque du soleil utilise depuis plusieurs annees des logiciels de previsualisation lors de la phase de conception d’un nouveau spectacle. Ces outils sont puissants pour simuler les decors, les agres et les eclairages prevus. Quand vient le temps de simuler la performance des acrobates, ces logiciels utilisent une representation tres stylisee, sous forme, par […]

A significant fraction of wet organic waste streams within typical municipalities include food wastes (collected by many as source separated organics), and sludges or biosolids. In Canada, such wastes are mostly going to landfill or being land applied to recover some nutrient value. Anaerobic digestion (AD) for disposal of organic waste is an attractive option […]

Bridge bearings are used to support the weight of the bridge superstructure on the bridge piers. These bearings allow for the bridge to expand and contract during thermal cycles and accommodate the varying forces on the bridge throughout its life. Elastomers within the bearing are flexible enough to allow for these rotation and translation demands […]

The COVID-19 pandemic is an on-going health crisis which is having a dramatic impact on how people in Canada and around the world live their lives. In response to the rapid spread of the virus, provincial and federal governments have enacted a number of ‘physical distancing’ measures, including closures of publicly-funded schools and all non-essential […]

Driven by economic, technical and environmental reasons, the energy sector is moving into an era where Distributed Generation (DG) will meet a large segment of increasing electrical energy demand. Local distribution companies are required to accept a given percentage of customer-owned renewable DG units in their system. Generally, DG introduces new possibilities such as shaving […]

Work improvement is critical for performance increase in business environments. It is used to identify bottlenecks and inefficiencies in the manufacturing and other production processes, and to improve work performance by removing non-value-added activities. To conduct work improvement, the Lean Manufacturing concept is often used along with the Value Stream Mapping (VSM), a tool for […]

Unmanned Arial Surveillance is rapidly gaining acceptance for various applications, such as monitoring of long power transmission lines, pipelines and mass transit systems that extend for hundreds of kilometers. Unmanned Aerial Vehicles (UAVs) such as drones provide the flexibility to reduce costs. In the case of natural disaster occurrence such as earthquake, flood or hurricane, […]

The Superplastic Forming process involves gas injection from a variable pressure supply, to form a heated metallic sheet into a complex automotive body panel shape onto the surface of a die. The current process involves excessive forming times which allow residual stresses to relax and avoid cracking and tearing. Research shows that pressure pulsations of […]

High-strength aluminum alloys (AA) are extensively used for landing gears given their low density compared to steel. All AA parts undergo special processes after machining such as shot peening and anodizing. Because the impact of the special processes on the fatigue properties of the material is not very well known, conservative security factors are used […]

This research aims to provide an affordable, clean energy alternative to meet the world’s cooling demands. As global warming, urbanization, and society’s dependency on digital storage increases, the world’s cooling demands continue to rapidly grow with predictions showing that they will outweigh heating demands by 2060. The majority of these demands are currently being met […]

Polytechnique Montréal va développer un simulateur numérique pour recréer la réalité actuelle des stations de pompage en série dont le fonctionnement est basé sur des niveaux, ajouter un contrôle virtuel basé sur le débit et opérer les stations à distance en faisant un diagnostic en temps réel, dans le but d’effectuer une économie d’électricité du […]

Reliable high speed wireless data transmission is the primary goal of future cellular systems. A key impediment towards that goal is interference on receivers from transmitters in adjacent cells. Coordinating transmissions between clusters of transmitters is one way of solving this problem. This coordination is more difficult when the types of transmitters and cell sizes […]
