Illinois-Indiana Sea Grant 2015 Summer Internship Announcement
Illinois-Indiana Sea Grant announces the following positions for the 2015 Summer Student Internship Program. Successful applicants will spend 12 weeks working closely with a Sea Grant specialist on issues affecting the Great Lakes. Internships include research, communications and outreach components. Applicants will also have the opportunity to participate in activities outside of their specific internship duties.
For 2015, internships are available in the following areas:
- Field Sampling
- Human Dimensions
- Website Development
Interns will be paid $12/hour for 37.5 hours per week. Some travel and/or weekend work may be expected. Interns are responsible for the cost of housing plus transportation to and from their work place. Work-related travel will be funded by the Sea Grant host. Applications packets are due on March 16, 2015. Successful applications will be notified of their acceptance by early April 2015. Internships are expected to start May 2015 and end August 2015. Starting dates are flexible.
Smida Wins NSF Career Award
Besma Smida,Ph.D., Purdue University Northest Assistant Professor of Electrical Engineering, has received the prestigious National Science Foundation (NSF) Faculty Early Career Development (CAREER) award.
This five-year $425,000 award will support development of creating reliable full-duplex wireless networks by means of reflected power.
One key limit to spectrum utilization efficiency involves the current practice of half-duplex communication, in which a node cannot transmit and receive on the same frequency at the same time. Some recent studies have provided experimental evidence and methodologies for full-duplex communication. However, to date, all full-duplex demonstrations have been predicated on the principle that the transmitter and the receiver must generate their own radio-carrier waves independently, which in practice results in a high level of self-interference at both nodes. The objective of this CAREER project is to create reliable full-duplex wireless networks by means of reflected power.
Intellectual Merits: We will employ backscatter modulation (BM), where electromagnetic waves are modulated and reflected by the same antenna that receives them. Within this framework, the end-user receives a signal free of self-interference. This research offers a new paradigm for two-way wireless networks: rather than avoiding self-interference as in half-duplex – or combating self-interference as in full-duplex – nodes will re-use the received interfering radio-carrier waves to transfer information. The results of this analysis will advance our knowledge of antenna scattering for a wide range of applications. The proposed implementation in hardware will incite an exchange between algorithm innovation and hardware implementation, pushing the limit of spectrum-efficiency communication.
Broader Impact: We will embed the proposed research into pedagogy by creating a center of wireless communications at Purdue University Northwest. The center will provide varied opportunities for undergraduate and graduate students to gain direct experience in testing, evaluating, and improving BM for full-duplex communications. Given the current pervasiveness of two-way wireless communication, the results of this research can be used to significantly increase the spectral efficiency of future wireless networks.
