Integral Abutment Bridges (IABs) are unique structures in the sense that they are rigid compared to typical bridges that have bearing connections. Bridges are designed to withstand forces sourcing from its own weight and ongoing traffic as well as temperature forces. As the temperature varies (cyclic in nature), the bridge experiences contraction and expansion forces that result in varying internal stresses within the structure that causes the bridge to wear.
This project is motivated by the demands for automation of industrial structure inspection. An autonomous re-configurable robot system is proposed to facilitate the inspection of structures with confined spaces, like airframes or ship hulls. The robot will be able to realize various types of legged locomotion by means of configuration changes. The general objective of this project is to develop a legged robot system that is fully autonomous and adaptable to the structures under operation.
Orange-footed sea cucumber (Cucumaria frondosa) is the most common sea cucumber found in the North Atlantic Ocean. This species is mainly fished for its edible body wall and other remaining body parts are discarded as processing waste. However, all the body parts are rich in protein and production of protein hydrolysates is identified as an efficient method to upgrade the by-products. The protein hydrolysates and peptides so produced exhibit excellent functional and biological properties. These properties show great potential for utilizing as functional ingredients in the cosmetic industry.
Agricultural producers are concerned about producing food, increasing productivity, and making sustainability, while drones along with governments, technology leaders, and industry are playing an important role as a part of solution of this . This drone imagery is for farmers so that, they can fly their fields, and not only pinpoint issues such as, irrigation leaks, leaf color variation or pest, but also highlight where these issues are occurring. But the image processing time is often too late to remedy that solution.
Vertical farming is an innovative urban agricultural practice that can efficiently use resources to supply food for communities, while high energy cost is becoming an economic bottleneck to long-term development and growth of the technology. The potential exists to capture and take advantage of by-products generated from the biological decay of the organics during the composting process, including CO2 gas and heat.
The goal of the proposed research project is to evaluate the usability of a new module for an existing eLearning program for classroom teachers called Teacher Help. The new module is designed to provide training in evidence-based classroom management strategies to decrease disruptive classroom behaviour.
Computer simulations have been widely used by the offshore and marine industry, but they typically use different software to simulate different components of a single operational scenario. For example, the tool can be used for the analysis of wave loads of a moored structure in ice infested areas, eliminating the need for analyzing wave load, mooring tension, and ice loads, separately.
With the advantages of swimming with quiet, compliant, and continuous strokes, soft robot fish have significant potentials to be used in the study of marine life and ocean environment quietly without disturbing marine animals. Our project is to design and build a robot fish that is self-contained and capable of mimicking body kinematics of biological fish in nature. A new actuation mechanism is proposed in this project. It will efficiently transmit the motor power to the continuous oscillation of soft tail to allow the robot fish to maneuver in the water.
A swarm of robots should be available on the board of a vessel or oil rig so they will be deployed when spill occurs. Based on our existing know-how knowledge and technology, the swarm of robots automatically detect the boundary of the oil, then they deploy inflatable booms to contain the oil. After they successfully contain the spill by detecting whether or not the booms achieve a close loop, the swarm continues to expand its searching area until it could not find any new spill.
Imagine a freezingly cold winter day with the strong wind blowing outside your house somewhere in Newfoundland, and you are comfortably sitting in your room with heating and warm water - even during a power outage! This could be realized with a novel device that directly converts the wind energy to heat. This project aims to develop such a technology. The kinetic energy from the rotational motion of a small wind turbine is converted to thermal energy through fluid agitation and friction in a unique heat generator with specially designed rotating blades, baffles, and working fluid.
