Provide an outstanding educational program that enables our graduates to become leaders in their professions by imparting fundamental principles, skills, and tools to innovate and excel.Pursue the discovery of fundamental knowledge and its applications to position the department among the leaders in research.Respond to the needs of the State of Iowa and the nation by building a strong outreach program that serves industry and the engineering profession. HONORS and AWARDS ENDOWED CHAIRS AND PROFESSORSHIPSDavid FELLOWS ADVANCED ELECTRONICS AND MATERIALS AEMThe Advanced Electronics and Materials group includes three synergistic engineering areas represented by the Center for Nondestructive Evaluation, the Microelectronics Research Center, and the Analog and Mixed-Signal VLSI Design Center. Many ECpE faculty work at these centers, while others work wholly within the ECpE department.Research includes three-dimensional electromagnetic field simulation and modeling, nondestructive material evaluation instrumentation and research, advanced materials processing, thin film semiconductor devices, photonic bandgap materials and devices, solar energy conversion, magnetics, and mixed-signal VLSI design from low frequencies up through millimeter wavelengths.Robert Weber, Chair NONDESTRUCTIVE EVALUATION AND ELECTROMAGNETICS Primary MembersJohn AEM FAST AND EFFICIENT ALGORITHMS IN COMPUTATIONAL ELECTROMAGNETICSThe goal of this project is to explore and develop fast and efficient algorithms in computational electromagnetics in order to solve scattering and radiation from complex, large-scale objects. As a principal research scientist in the Center for Computational Electromagnetics at the University of Illinois, the PI developed a three-dimensional fast multipole method, a multilevel fast multipole algorithm, and the fast Illinois solver code (FISC) for use in largescale electromagnetic analysis. To date, more than 400 copies of FISC have been distributed to government and industrial users. In addition, higherorder methods for applying the method of moments have been developed for solving integral equations, resulting in faster convergence, less CPU time, and fewer memory requirements. We also developed fast algorithms for lowfrequency applications of EMC/EMI and approaches for broadband simulations of electromagnetic scattering using frequency domain methods. We are developing well-conditioned integral equations, fast and efficient algorithms for electromagnetic scattering and radiation, light scattering from biological cells, and de-embedding algorithms and electromagnetic modeling and simulations for interconnects and RF components over conducting silicon.

They were identified as β-sitosterol (PS1), 31-norcyclolaudenone (PS2) and (24R)-4α, 14α, 14-trimethyl-5α-cholesta-8, 25(27)-dien-3β-ol (PS3). Of these, PS2 exhibited the highest inhibitory activity against α-glucosidase with an IC 50 value of 11.33 μg/mL -1 compared to 283.67 and 43.10 μg/mL -1 for PS1 and PS3, respectively. For α-amylase activity, the order of inhibition (IC 50 ) was 52.55, 76.25 and 532.05 μg/mL -1 for PS1, PS2 and PS3, respectively. PS1 proved to be an uncompetitive inhibitor of α-amylase with a K m value of 5.51 μg/mL -1 compared mixed-type inhibition by PS2 and PS3 with respective K m values of 52.36 and 2.49 K m μg/mL -1 . Using the BSA-fructose model, PSI and PS2 both significantly inhibited the formation of advanced glycation products (AGES). The latter is considered to play a pathogenic role in the progression of oxidative-diseases such as diabetes and its complications. /me Effect of hazelnut roasting on the oil properties and stability under thermal and photooxidation Using response surface methodology (RSM), optimal roasting conditions were determined for two hazelnut cultivars, Delisava and Kara Findik. Similar roasting conditions were observed for both hazelnut cultivars with some minor differences. A slightly higher roasting temperature of 122.43°C over a short period of time (22.12 min) was reported for Kara Findik compared to 114.24°C for 27.21 min. for Desava oil. A greater oxidative stability was observed for Kara Findik oil when stored under Schaal oven conditions at 60°C compared to Desava oil. The opposite was evident for photooxidation in which a lower oxidative stability was reported for Kara Findik oil compared to the Desava oil. Using this information, large scale production of hazelnut oil will require further investigation. /me Ozkan, G. et al., Eur. Food Res. Technol. 2016, 242, 2011-2019 Comparison of microwave and conventional frying on quality attributes and fat content of potatoes This paper compares the quality attributes (moisture, fat, color, and relaxation modulus) of conventionally fried and microwave fried French fries. Real-time pressure and temperature were monitored during frying and related to fat uptake. Frying of French fries was conducted at 177, 185 and 193°C at 60, 90 and 120 sec. French fries with reduced fat was obtained by microwave frying at 185 and 193°C for 120 sec. Compared to conventional frying, higher gage pressures were observed at all temperatures during microwave frying. The microwave produced French fries had higher color values and were yellower at the higher temperatures compared to those produced by conventional frying. Using a consumer test, no significa...
