Show morePublic officials’ communication has been explored at length in terms of how such their statements are conveyed in the traditional media, but minimal research has been done to examine their communication via social media. This paper explores the kinds of statements U.S. officials are making on Twitter in terms of the actions they are trying to achieve. We then analyze the correlation between these statements, Congressional communication network structures, and voting behavior. Our analysis leverages over 29,000 tweets by members of Congress in conjunction with existing DW-NOMINATE voting behavior data. We find that pro-social and self-promoting statements correlate with Congressional voting records but that position within the Congressional communication network does not correlate with voting behavior.

Show moreCow’s milk allergy and egg allergy are the two most prevalent food allergies in the United States. Enzyme-linked immunosorbent assay (ELISA), based on antigen-antibody reactions, is the most popular method used by the food industry to detect allergen residues. Thermal treatments are the traditional food processing methods, while high pressure processing (HPP) has increasingly been applied as an alternative food processing technology. This research examined how thermal and high pressure processing may affect the antigenicity and detectability of milk and egg allergens. The first part of this study examined the performance of four ELISA test kits (Veratox for Total Milk Allergen, Biokits BLG Assay Kit, ELISA Systems Casein and BLG Residue Assays) for quantitation of milk residues in packaged foods that have been subjected to different degrees of processing. Whether standard reference materials (SRM) can be used to compare the relative performance of these test kits was also examined. Commercial food products including ice creams, cookies, fried fish sticks, and canned soups were chosen to represent foods that have been pasteurized, baked, fried, and autoclaved, respectively. Calcium caseinate, NIST non-fat dry milk (NFDM) SRM #1549 and USDA certified whey protein were used as reference standards. Veratox and ELISA Systems Casein kits, both of which use NFDM as the calibrator, showed similar readings for ice cream. However, the Casein kit tended to register a lower level of milk residues in other thermal processed products, especially for canned soup where the test kit showed a 50-fold lower level of milk residue than that reported by the Veratox kit. Using whey protein as a reference standard, the two BLG test kits showed a similar level of whey protein equivalent in ice cream, but for fish stick, cookie, and canned soup samples, the x ELISA Systems BLG kit registered values about 4-, 39-, and 17-fold lower than the values obtained by the Biokits BLG test kit, suggesting that the ELISA Systems kit has a greatly reduced sensitivity for foods that have received heat treatments. When using NIST NFDM as the reference standard, the Veratox and Biokits registered the same level of NFDM equivalent in ice cream, but the Biokits gave a higher level for the fish, cookies, and soup samples, indicating that this kit has a better sensitivity for heat processed food. Overall, different test kits registered different levels of milk even for the same commercial sample. The use of common reference materials provides a means for comparison, but the quantitation of milk residues is still complicated by the different heat sensitivity of each test kit. The second part of this study evaluated the impact of thermal processing on the solubility and antigenicity of egg allergens. Solutions (5 mg/ml sample in PBS) of Henningsen dehydrated whole egg, ovalbumin (OVA), and ovomucoid (OVO) were subjected to three different thermal processing conditions (heated in water at 60℃, 100℃, and autoclaved) for 10 minutes. The solubility of the unheated and heat-treated samples was determined by the BCA total protein assay. Changes in the antigenicity (IC50 value) of egg proteins after thermal treatments were determined by inhibition ELISA. Differences in the antigenicity determined as affected by the use of different target protein, coating antigen, and primary antibody were determined. At 60℃, the solubility and antigenicity of heat treated samples showed similar results as those of untreated sample. For sample treated under other conditions, different heat treatments affect the solubility of egg protein samples differently. Different heat processes, different antigen-antibody combinations, and different extraction methods could affect the IC50 values xi differently, which means the antigenicity changed differently due to different influence factors (e.g. IC50 values of OVO always increased after boiling or autoclaving treatment no matter which coating antigen and primary antibody chose, however OVA and whole egg powder showed uncertain changes). The last part of this study evaluated the impact of high pressure processing on the solubility, antigenicity, and the detectability of egg allergens. Solutions of dehydrated whole egg, OVA, OVO, and Egg Beater (ConAgra Foods) were subjected to high pressure treatments for 3 min under 4 conditions (400MPa 20℃, 400MPa 60℃, 600MPa 20℃, and 600MPa 60℃). The amount of protein in the high pressure treated samples was determined by BCA assay and the Veratox egg allergen test kits. Changes in protein antigenicity were determined by inhibition ELISA assay. The results showed that high pressure treatments under all 4 conditions did not affect the solubility and antigenicity of the egg proteins in the treated samples. HPP did not affect the detectability of these proteins by Veratox test either.

Show moreDynamic models of high temperature short time (HTST) pasteurization systems can be developed by using empirical model development paradigms such as transfer functions and times series models. Properly designed experiments that excite all output variables provide good data that enable the development of accurate dynamic models. These models are used in feedback control and statistical process monitoring system design. The methodology for time series model development for HTST pasteurization processes is illustrated by using data collected from a pilot scale HTST pasteurization system.

Show moreNatural gas is becoming rapidly the optimal choice for fueling new generating units in electric power system driven by abundant natural gas supplies and environmental regulations that are expected to cause coal-fired generation retirements. The growing reliance on natural gas as a dominant fuel for electricity generation throughout North America has brought the interaction between the natural gas and power grids into sharp focus. The primary concern and motivation of this research is to address the emerging interdependency issues faced by the electric power and natural gas industry. This thesis provides a comprehensive analysis of the interactions between the two systems regarding the short-term operation and long-term infrastructure planning. Natural gas and renewable energy appear complementary in many respects regarding fuel price and availability, environmental impact, resource distribution and dispatchability. In addition, demand response has also held the promise of making a significant contribution to enhance system operations by providing incentives to customers for a more flat load profile. We investigated the coordination between natural gas-fired generation and prevailing nontraditional resources including renewable energy, demand response so as to provide economical options for optimizing the short-term scheduling with the intense natural gas delivery constraints. As the amount and dispatch of gas-fired generation increases, the long-term interdependency issue is whether there is adequate pipeline capacity to provide sufficient gas to natural gas-fired generation during the entire planning horizon while it is widely used outside the power sector. This thesis developed a co-optimization planning model by incorporating the natural gas transportation system into the multi-year resource and transmission system planning problem.This consideration would provide a more comprehensive decision for the investment and accurate assessment for system adequacy and reliability. With the growing reliance on natural gas and widespread utilization of highly efficient combined heat and power (CHP), it is also questionable that whether the independent design of infrastructures can meet potential challenges of future energy supply. To address this issue, this thesis proposed an optimization framework for a sustainable multiple energy system expansion planning based on an energy hub model while considering the energy efficiency, emission and reliability performance. In addition, we introduced the probabilistic reliability evaluation and flow network analysis into the multiple energy system design in order to obtain an optimal and reliable network topology.

Show moreThis thesis gives a brief outline of how the microscopic representation enters into a good description of the elasticity of a fluid. We first introduce the hydrodynamics by three continuity equations. Due to its macroscopic background, we point out its limitation that it does not fit well with the elastic behavior of the fluid. Therefore we introduce the microscopic description of the system. In order to connect the elasticity which is obviously involved in the non-equilibrium state of a fluid, we discuss how non-equilibrium mechanics could be related to equilibrium mechanics by the assumption that the system is not far away from equilibrium. Under this assumption, an analysis of equilibrium mechanics is necessary, and combining with the microscopic representation, we derive the generalized Langevin equation as an equation of motion of the momentum current, which is endowed with the elastic property, consistent with observations of the fluid.

Show moreOne of the most influential parameters in structural design of tall buildings, in addition to gravity loads, is the lateral load resulting from wind and to some extend earthquakes. Tall buildings have to be designed for a larger base shear, resulting from wind forces rather than from seismic forces; however, ductile detailing is used when needed to account for seismic demands. The wind effect occurs primarily in two main modes of action: across wind and along wind. Wind also produces three different types of effects on tall buildings: static, dynamic, and aerodynamic. Structurally, static effect is measured independent of time, while dynamic analysis takes into account the system responses to the changes through the period of time. When the building is flexible, it interacts with the wind load and affects its response, which is called aerodynamic effect. To reduce the static and dynamic impact, there are two main solutions: Architectural and Structural. Architects can mitigate wind effect on tall buildings by designing the form aerodynamically or at least by utilizing aerodynamic modifications, which are categorized in macro and micro modifications such as tapering and setback. Structural engineers can reduce wind effect by choosing and designing efficient structural systems regarding the form of the buildings such as tube systems and diagrid system. This thesis, by utilizing the architectural and structural strategies to reduce wind effect, introduces a new design method in the realm of tall buildings. An innovative design method of tall buildings calls for an integrated approach with considerations for both architectural and structural design requirements and concepts. This design method which considers integrated architectural and structural concepts to reduce the along wind effect, for this particular research, is an effort to achieve the minimum weight of the structure. This method creates an innovative computational workbench to design efficient tall buildings, regarding the along wind effect. This can be achieved by connecting an architectural parametric design procedure in AutoLisp (AutoCAD) to generate the models with different forms of modifications, a Computational Fluid Dynamics program (ANSYS) to do the CFD simulations, a structural analysis program (SAP2000) and the ParaGen visualization interface to consider and compare the results to evaluate the models regarding the criteria such as weight of the structure (ParaGen has also a Genetic Algorithm based optimization procedure that is not used in this research). In this research, the most important architectural and structural parameters of seventy-three of the tallest buildings are also studied. Based on the information gathered, the future trend in the geometry and form and also the structural design used for tall buildings can be predicted. It is necessary to mention, based on the past and current trends in architectural features and structural design of tall buildings, and also the future prediction, the required architectural and structural parameters for an innovative proposed design method can be helped. However, it is not clear whether this trend is in a right way or not, it has to be improved based on the architectural and structural efficient parameters. The research shows that a careful study of core design concepts in architectural features and structural design of tall buildings, along with an integrated approach considering various design requirements, can be an effective method in design of new generation of tall buildings.

Show moreInformal observations of a practical and creative approach piloting Blended Library Instruction for undergraduate Civil Architecture and Engineering students, in collaboration with faculty. At Illinois Institute of Technology students don’t receive library instruction as a required class or in tandem with a composition class. Faculty will schedule one-time sessions, which ideally should be planned with a class assignment in mind, but students are rarely engaged with a one time instruction. Many have IKIA syndrome or I Know It Already syndrome. The Millennials are a group that has integrated technology into every aspect of their lives and they assume that retrieving useful or necessary information will be easy. When they discover this isn’t the case lack of time, heightened anxiety, and increased frustration can prevent them from doing their best work. By intentionally creating a similar crisis prior to library instruction, students were more interested in what they stood to gain during pending library instruction. In this presentation we will discuss: 1) A creative means of delivering library instruction to a traditionally challenging population: engineering undergraduate students 2) Qualitative information collected via multiple assignments and interpreted in a quantitative fashion, as well as our observations. 3) A method for preparing students for library instruction that can be applied in almost any discipline without asking the instructor to sacrifice class time.

Since there are limits of reducing variation through process in traditional industrial management and it is hard to monitor the process when the engineering domain knowledge is insufficient. We investigated statistical methods based on piecewise tree regression model including: CART, Bayesian CART, Bayesian treed linear model and Bayesian treed Gaussian process to multistage manufacturing process. The difference performances between models were discussed in a wafer manufacturing process case as a result comparison.
