Dynamic Control of Robotic Arm

In the design of robotic mechanisms, dynamic balancing i.e. force and moment balancing is an important issue. The robotic mechanism’s accuracy and efficiency are affected because of the unbalance. Moreover, the forces and moments cause fatigue, noise and disturbance in its structural base. Previous research done by Prof. Chris Zhang include a force balancing method that is termed as adjusting kinematic parameters (AKP) for robotic mechanisms or real-time controllable (RTC) mechanisms. This research includes dynamic balancing method for planar mechanisms only i.e. two dimensional.

Understanding the social function of pre-trial detention: A comparative study between Canada and France

Understanding the recent frequent use of pre-trial detention in Canada and France is crucial, considering its impact on the lives of individuals that are detained while still being presumed innocent, as well as the significant financial costs for the state. This project aims to compare the institution of pre-trial detention and examine the role that it is currently playing in Canada and France – two countries that share different legal traditions namely common law and civil law. The objectives of this research are threefold.

Extrusion of Metal Matrix Composite material: orientation of reinforcements and transfer of properties

The aim of this project is to develop and characterize metal matrix composite materials for applications in the field of power electronics and automotive. The material under study are constituted by a copper or aluminum matrix, reinforced by carbon (fibers or platelets) and it is known that the composite properties depend on the orientation of the reinforcements. The objective of this research is to study and to evaluate the effect of a deformation (e.g extrusion) of the material on its thermal, electrical and mechanical properties.

In Vivo Reprogramming of Spiral Ganglion Glial Cells into Primary Auditory Neurons

Sensorineural hearing loss involves damage to hair cells, the sensory transducers of the auditory system, and/or the auditory neurons that transmit this information to the brain. Once these cells are lost the body does not naturally regenerate them. Elsewhere it has been shown that cells of one type may be converted into another cell type. This project involves using viral expression of select transcription factors in the spiral ganglion to convert resident cells into new auditory neurons to restore hearing.

Investigating productive uncertainty in technological intelligence practices

This project aims at investigating productive uncertainty as a determinant factor in stimulating the exploration of innovation. Data will be collected through stakeholder interviews and observations of technological intelligence practices at Université de Bordeaux’s Via Inno lab. Via Inno engages with industrial partners to explore future development opportunities, which present an ideal case study to explore conditions of uncertainty.

Investigation of Proteomic Changes Following Chilling Exposure in Resistant and Sensitive Zea Mays

A plants’ ability to withstand chilling and frost damage will dictate the geography in which production can occur. Global warming is predicted to increase chilling and frost injury in crops. It is important to note that frost injury is one of the key factors limiting production. In corn, chilling injury is an ongoing constraint for global production and expansion which affects food, feed and fuel supplies. Corn is an important model system as it is the largest crop, on a tonnage basis, produced in the world.

Proteome analysis of field versus chamber acclimated winter wheat and rye crowns

The most critical region for winter wheat (Triticum aestivum L.) winter survival is the crown. Exposure to different environmental cues during cold acclimation improves the crown’s resistance to freezing. This key fact is not taken into account in the design of controlled environment experiments and may not reflect actual mechanisms of cold hardiness in the field. Acclimation to multiple environmental cues under fall field conditions could explain the improved freezing survival of field as opposed to chamber acclimated plants.

Neuromorphic Computing with Stochastic Binary Weights Based on Magnetic Tunnel Junctions

Many problems which are best solved by neural networks are exhibiting rapid growth in nascent and existing fields, such as natural language processing, and image recognition for self-driving cars. Current limitations in manufacturing technologies impose limits that prevent these performance demands from being met through conventional methods. Neuromorphic computing has been proposed as a potential solution for problems best solved with artificial neural networks.

The Odd Couple: Cancer and the Circadian Clock

Circadian rhythms are processes which allows animals to regulate their physiology based on time of day. These rhythms are controlled by the circadian clock, a group of transcription factors that form a feedback loop. Over 40% of the genome is transcribed rhythmically, implicating the clock in many physiological processes. The cell cycle is another process which takes ~24h to complete in mammals. This is due to several checkpoints which are present to prevent the cell from precocious progression leading to DNA damage.

Crystal Orientation-Wetting Property Relationships for Cerium Oxide

Improving the durability of superhydrophobic surfaces is of significant interest in the surface engineering community. We have recently developed a novel superhydrophobic coating with a hard nanocrystalline nickel matrix and embedded hydrophobic polytetrafluoroethylene (PTFE) particles. To further improve the mechanical robustness of the non-wetting coating, the soft polymeric PTFE particles were replaced with hard, hydrophobic cerium oxide ceramic particles. However, the intrinsic hydrophobic properties of cerium oxide are not well understood.
