Unlined pressure tunnels in sound rock, combined with pressurized sand traps at the downstream end, allow for low-cost construction of hydropower tunnel systems. This design concept is utilized plants across world. Currently, many such power are being upgraded higher installed capacity, which may result challenges trap efficiency. A physical scale model test, accompanied by 3D CFD simulations a...

Abstract The last decade saw the rise of digitalization and data-supported decision making in manufacturing industry: Fourth Industrial Revolution. This trend, also known as Industry 4.0, allows enterprises to discover uncertainties measure their real capability. One ways which 4.0 trends have been exploited is improvement maintenance, went from following planning-focused paradigms more proacti...

Many constructions are globally built with reinforced or prestressed concrete and a large part of them designed expected to resist earthquake actions in addition gravity loads [...]

As a rapidly growing cyber-physical platform, unmanned aerial vehicles are facing more security threats as their capabilities and applications continue to expand. Adversaries with detailed knowledge about the vehicle could orchestrate sophisticated attacks that are not easily detected or handled by the vehicle’s control system. In this work, we purpose a generic security framework, termed BlueB...

Supply Chain Management involves the material and information management through the entire supply chain (SC), from the initial suppliers to the end users, going through manufacturing and distribution facilities. The main objective is to achieve suitable economic performance taking into account the large amount of constraints featuring this kind of problems. In this work, decisions that have a ...

Environmental data repositories are frequently stored as a collection of packed binary files arranged in an intricate directory structure, rather than in a database. In previous work, we 1) show that environmental data is often logically equipped with a topological grid structure and 2) provide a data model and algebra of gridfields for manipulating such gridded datasets. In this paper, we show...

AUTOBAYES is a fully automatic, schema-based program synthesis system for statistical data analysis applications. Its core component is a schema library. Le., a collection of generic code templates with associated applicability constraints which are instantiated in a problem-specific way during synthesis. Currently, ALTOBAYES is implemented in Prolog; the schemas thus use abstract syntax (Le., ...

The use of fibre reinforced polymer (FRP) for retrofitting and strengthening concrete structures provides an attractive and economical solution to increasing their strength and ductility. This paper reviews some of the Canadian projects which have been completed using this material. The selected projects are sponsored by the Canadian Network of Centres of Excellence on Intelligent Sensing for I...

Several different carbon-capture technologies have been proposed for use in the cement industry. This paper reviews their attributes, the progress that has been made toward their commercialization, and the major challenges facing their retrofitting to existing cement plants. A technology readiness level (TRL) scale for carbon capture in the cement industry is developed. For application at cemen...
