Think about how far telecommunications have come in the past century, from the telegraph, to the wireless telephone, to being able to access the Internet from nearly anywhere on the planet. Along that path are a series of small evolutions that, when viewed from a distance, are revolutionary.
Christian Schlegel is trying to spark the next communications evolution 鈥斅燽ut not through air, as with most telecommunications, but underwater.
Dr. Schlegel, the NSERC/Ultra Electronics Maritime Systems Industrial Research Chair in Wireless Information Transmission and Networking at pilipili漫画, is the lead researcher on one of four Nova Scotia projects to receive funding earlier this month through the Atlantic Canadian Opportunities Agency鈥檚 (ACOA) Atlantic Innovation Fund.
Dr. Schlegel鈥檚 research into new algorithms to support high-speed underwater communications networks received more than $2.3 million in funding.
鈥淧art of the opportunity with this particular grant is to move towards prototyping, making this research more ready for industry to pick up and integrate into their products and development,鈥� explains Dr. Schlegel, part of Dal鈥檚 Department of Electrical and Chemical Engineering and head of the Ultra Maritime Digital Communications Centre (www.umdcc.ca).
Halifax is, of course, a hotbed for work and research in the oceans, and when it comes to communicating underwater, the primary method of high-speed communications uses acoustics 鈥� the propagation of pressure waves.
鈥淭hat presents its own challenges, including that the subsea channel is a very noisy channel; you鈥檙e not the only one making noise down there鈥� says Dr. Schlegel. 鈥淲e鈥檙e looking at bringing in a new generation of computational algorithms, modifying and adapting them to this particular problem. And if we can bring them to a prototype level 鈥� show their superiority over traditional methods, prove they can carry more data 鈥斅爐hen we鈥檒l have accomplished what we set out to do.鈥�
The research could have applications in everything from environmental research, to basic science, to military and commercial uses 鈥斅爎eally, anyone who has an interest in knowing what鈥檚 going on under the ocean鈥檚 surface. Dr. Schlegel adds that students will be a key part of the five-year research project.
鈥淲e have students do a lot of research, understanding the problem in analytical mathematical approaches. Then we model things in the computer, studying certain ways of signaling, see how they work, what issues crop up. And when we have an algorithm that seems to be a good candidate, and we have our bases covered, we move into what this grant is really for: the transition of the algorithm onto a hardware platform using programmable integrated circuits.鈥�
Dr. Schlegel sees this as a great research and development opportunity, given the amount of oceans-related work happening on Canada鈥檚 East Coast, but is conscious that it鈥檚 going to take a lot of hard work and partnerships to bring technology like this to market.
鈥淚t鈥檚 a great opportunity, but a fragile one,鈥� he says. 鈥淲e have to make sure people pull in the same direction and make the best use of the resources we鈥檝e been given.鈥�
More Dal projects awarded
Dr. Schlegel鈥檚 work wasn鈥檛 the only project with a Dal connection to receive funding through the Atlantic Innovation Fund earlier this month: in fact, three of the four Nova Scotia projects are associated with the university.
Dr. Steven Beyea, associate professor in the Department of Diagnostic Radiology at pilipili漫画 Medical School, is the scientific lead of BIOTIC, the Biomedical Translational Imaging Centre. It received $2.9 million from ACOA which, when combined with a $2.9 million contribution from the QEII Foundation, will develop new MRI applications providing clinicians with powerful tools to gain a deeper understanding of what鈥檚 happening in patients鈥� bodies. One technology will improve MRI鈥檚 ability to map brain function before surgery in patients with brain tumors, reducing risk; another is focused on accurately classifying prostate cancer while a third measures fat and iron present in patients with liver disease. The project is in collaboration with clinical scientist Dr. Sharon Clarke, an assistant professor at Dal.
The third AIF grant associated Dal went to ABK Biomedical Incorporated, which counts Dal鈥檚 Daniel Boyd (Division of Radiology and Department of Oral Material Sciences) as its chief scientific officer and founder. The grant of $2.1 million focuses on the development and commercialization of new biomaterials to enhance the delivery of chemotherapy and radiotherapy for patients. Dr. Boyd鈥檚 novel biomaterials were recognized with top prize in BioNova鈥檚 Bioinnovation Challenge in 2011. (Read more about the research.)
