An Analysis of the Role of Water on the Effective Permittivity of Biological Materials Using Mixing Formulas
2:00 p.m. Friday, June 6, 2008

Abstract
The literature on the permittivity of biological materials shows discrepancies in the values reported by various sources. The effective permittivity of biological materials is dependent on its constituent materials. In this study, mixing formulas are reviewed and used to investigate the role of water content and state on the effective permittivity of biological materials. White matter, gray matter, muscle, skin and liver are used as examples of biological materials and their permittivity values are determined using the Maxwell-Garnet mixing formula for variations in water levels over a physiological range. The results show that the discrepancies found in literature can, to a great extent, be accounted for by the variations in water volume levels. Further, correcting for the presence of bound water, a wider range of permittivity values is achieved due to the low permittivity of bound water. All such changes are also shown to be maintained over a wide frequency range.
This study provides deeper insight into the effect of water content and state on biological materials. Researchers can benefit from this work by accounting for water content and state when modeling biological materials and assessing the effects of electromagnetic fields.

Control of Wind Generator for Oscillations
12:30 p.m. Tuesday, Sept. 23, 2008
in EE 123
by Dr. Lingling Fan
ECE Dept.
NDSU
Fargo
Abstract
Oscillations, especially inter-area oscillations are one of the challenges in power system long distance transmission. Inter-area oscillations limit the line capacity to a value much lower than the thermal capacity. With more and more states requiring renewable energy portfolio standards, large-scale wind power is expected to integrate into the grid. In Minnesota, 25% of the energy is expected to be from renewable energy by 2020. Wind power is the major component of the renewable energy portfolio in Midwest region due to the abundant wind resources. Wind farms are usually located at remote areas from the loads (metropolitan areas). Thus long distance transmission is required for wind power to be delivered to the loads. This situation increases the demand of long distance transmission and inter-area oscillations become an evident challenge in the future power system with large-scale wind power.
In this talk, the impact of wind generation on inter-area oscillation will be analyzed and the principle of oscillation control design will be explored. The alternative options along with future research plans are laid out.

Parallel and Distributed Simulation and Its Applications
12:30 p.m. Tuesday, Oct. 7, 2008
in EE 123
by Dr. Yan Gu
Department of Computer Science
NDSU
Fargo
Abstract
Enormous amounts of memory and computation power are required for simulation of large, complex systems such as telecommunication networks. Multiprocessor computer systems have motivated an extensive amount of research in the execution of discrete event simulation programs on high performance computing facilities.
In this talk, I will first give introductions to the concepts of parallel discrete event simulation and discuss related research problems. Then I will introduce my research work on utilizing parallel discrete event simulation for remote network emulation. Finally I would like to discuss potential research opportunities of large scale simulation in other areas. Top
Electronic Elections
12:30 p.m. Tuesday, Oct. 21, 2008
in EE 123
by Dr. Rajandra Katti
Electrical and Computer Engineering
NDSU
Fargo
Abstract
In this seminar the role of cryptography in electronic elections is explored. The requirements of a fair election such as universal verifiability, privacy, and robustness are described. These requirements are then translated into cryptographic equivalents in order to obtain a simple electronic election scheme.
Privacy of a person's vote is obtained using ElGamal encryption. Verification of the tally is done using homomorphic encryption. To avoid collusion between election officials, secret sharing schemes are introduced. Finally, proofs of knowledge are used to prove that a person's vote was properly cast.
Schemes developed for e-elections are also useful in other applications such as privacy of medical records, and IP protection. Top
Introducing the Center for Protease Research Core Facilities: Capabilities and Services
12:30 p.m. Tuesday, Nov. 4, 2008
in EE 123
by Dr. Jodie Haring
Chemistry, Biochemistry and Molecular Biology
NDSU
Fargo
Abstract
This informational seminar is being presented to introduce the Center for Protease Research Core Facilities, and to provide the opportunity for faculty and students in the ECE department to discuss with Rajesh and Jodie how their Core facilities could help researchers in ECE achieve their research goals. Dr. Rajesh Murthy, manager of the Core Synthesis Facility located on first floor Dunbar Hall, will be discussing the synthetic and analytical capabilities of his facility. Dr. Jodie Haring, manager of the Core Biology Facility located on 3rd floor IACC, will provide information on the equipment located in the molecular biology and tissue culture labs, training opportunities, and the different fee structures in place for the use of the facility. Handouts will be available with details for both Facilities as well as contact information for the two managers.

Optimization of Strategies/Heuristics for Delay Tolerant Ad-Hoc Networks
12:30 p.m. Tuesday, Nov. 18, 2008
in EE 123
by Prof. Pascal Bouvry
Computer Science and Communications
Luxembourg University
Kirchberg Campus
Abstract
Delay tolerant mobile ad-hoc networks (DTN) and hybrid networks require new generations of protocols and middleware in order to enable context-aware services and mobile grid computing. The underlying optimization issues are multi-objective by nature: e.g. optimizing the bandwidth use, the cost and efficiency of such services. We propose an approach based on the use of meta-heuristics for fine-tuning parameters of distributed lightweight strategies/heuristics for local decision-making. The fitness function representing the global behavior of the network relies on network characteristics such as network density and mobility models. We demonstrate the use of this approach for broadcasting and information gathering on DTNs, for trust management for MANETs, and for choosing injection points for hybrid networks. New generations of meta-heuristics such as co-evolutionary and cellular genetic algorithms are used for the optimization process.

Mathworks Tools Presentation
12:30 p.m. Tuesday, Dec. 2, 2008
in EE 123
by Bob Weinmann and Ed Schwind
Appareo Systems
Fargo, ND
Abstract
Due to the ever increasing power of embedded microcontrollers and DSPs, the complexity of embedded software has increased as well. In order to manage this higher level of complexity, higher levels of abstraction are necessary. To this end, model based coding has gained popularity because of the ease of rapidly prototyping code, allowing consistency during all steps of the development cycle, and generating documentation directly from the model.
The Mathworks tool suite including MATLAB, SimuLink, Real-Time Workshop, and Embedded Coder provide a higher level of abstraction and the ability to generate C code directly from a Simulink model, simplifying the development of embedded code, while maintaining consistency at all levels of design and simplifying the documentation process.
