Mitacs intern gains useful insight into industry

Over the course of his Accelerate internship Zaifman, a postdoctoral fellow at the Chemistry department of the University of British Columbia, partnered with AlCana, a Vancouver biotechnology company developing lipid nanoparticles, which show great potential as a new means for the targeted delivery of therapeutics.

Transport Layer Protocol Design for Cognitive Radio Systems

Recent studies have shown that many licensed spectrum bands are under-utilized, which form
spectrum holes [1]. The concept of cognitive radio was introduced in order to increase the
usage of the spectrum [2]. In cognitive radio systems [3], unlicensed users (which are also
called secondary users) can perform sensing over a wide range of spectrum bands. The
secondary users can opportunistically access the unused licensed bands from the legacy
spectrum holders (which are also called primary users). In order words, the secondary users

Understanding Scenes using Vision and Range Sensing

The Curious George project aims to construct a spatial-semantic modeling system featuring automated learning of object appearance and object-place relations from online annotated database, and the application of these relations to a variety of real-world tasks. The physical system currently developed at UBC, a visually guided mobile robot, can recognize objects in an environment based on imagery collected from the World Wide web, as demonstrated in an international contest known as the Semantic Robot Vision Challenge.

Examining Human Standing Balance Response with Independent Ankle Control

Standing balance is controlled by several inputs, including vision, vestibular sense, and ankle proprioception
Research studies in this field actively engage and manipulate these input mechanisms to examine their
effects on the balance output, mainly muscle actuation in the lower limbs. While significant progress has
been made, it is often difficult to isolate a single input and test its results on the output. The unique Robot
for Interactive Sensor Engagement and Rehabilitation (RISER) has been developed in the UBC CARIS

Wireless body area sensor network for biomedical applications

This project involves the design, implementation and testing of a short range wireless communication network employing technologies such as Bluetooth or ZigBee.

Photosynthetic protein based solar cells

In photosynthesis a protein complex absorbs photons and converts them to charge.  This process is achieved with extremely high quantum efficiency.  We are investigating several means of incorporating these protein reaction centres into photovoltaic devices.  The key is to efficiently extract charge from the reaction centres.  We are doing this using direct tunneling to electrodes or by passing charge to a mediator molecule that carries it to a selective electrode.  Ultimately we hope to demonstrate a very low cost method for converting solar to electrical energy.
