Abstract:
Abstract Mixing is the most important operation in polymer processing. Uniformity of the molecular weight, degree of entanglement, temperature, and composition, is the prerequisite for good performance. Mixing of molten polymers is always within the laminar (as opposed to turbulent) flow regime. This paper presents an overview of the effect of flow type on mixing. The distributive mixing is best modeled considering either laminar or chaotic mixing. Here the system is ”passive“, i.e.the rheological properties are identical and the interface is ”invisible“. Furthermore, the effects of flow and morphology are ”decoupled“. By contrast, the dispersive mixing is best modeled by means of microrheology, complemented by coalescence. Both models – the laminar mixing and the microrheology – show the unambiguous superiority of the extensional flows for dispersive and distributive mixing, in particular, when the viscosity ratio of two principal components is large. However this superiority is balanced by practical difficulties in generating a flow that may ascertain a high level of extension. Results of simulation and model experiments on drop deformabilty in converging and diverging (c-d) flow were used to develop a simple and inexpensive mixer capable of generating a high level of extension that lead to enhanced mixing capability. In consequence, an extensional flow mixer (EFM) was designed. In this device, a liquid mixture is repeatedly exposed to extensional flow fields and semi-quiescent zones. The c-d channels are of progressively increasing intensity. To reduce the pressure drop, and to prevent blockage, slit restrictions are used. The EFM (as well as its newer, dynamic version – DEFM) is fully adjustable, general-purpose mixers. Several its versions have been used for: polymer blending, incorporation of elastomers into resins, and dispersion of high viscosity polymers or ”gel particles“. For most mixing applications a singe-screw extruder equipped with either EFM or DEFM performed at least as well as a co-rotating, inter-meshing twin-screw extruder, with high efficiency screw configuration.

Abstract:
Ultrahigh molecular weight polyethylene (UHMWPE)/organic montmorillonite (OMMT) nanocomposites were prepared via a self-made vane mixer which could supply a synergy of ultrasound and extensional deformation. Structure and working principle of this novel mixer were illustrated in detail. Effects of the OMMT content, mixing time, and ultrasound treat time on composites’ morphology, rheological properties, and thermal properties were reported in terms of transmission electron microscopy (TEM), wide-angle X-ray scattering, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). X-ray diffraction (XRD) and TEM showed that the OMMT lay spacing increased from 2.82 nm to 3.29 nm and OMMT dispersed evenly in the matrix using this novel melt mixing equipment. It certified that the melt mixing procedure synergized by ultrasound and extensional deformation was very effective in the exfoliation of silicate layers and also the filler distribution and dispersion. DSC measurements revealed that the crystallization temperature ( Tc) had no visible change with increasing the OMMT content and the melting temperature ( Tm) and melting enthalpy crystallinity ( Xc) increased with the proper OMMT content. The higher Tm and Xc showed with the proper ultrasound treatment time, however, the Tc had no visible change. TGA showed that the onset temperature at which 20% weight loss of the material increased markedly in the case of UHMWPE/OMMT-1 wt% nanocomposite. The onset temperature slightly decreased with the use of ultrasound. Rheological analyses showed that all the samples exhibited non-Newtonian and shear thinning characteristics. Both the storage modulus and complex viscosity increased with continuous addition of the OMMT layers. It also indicated that the introduction of ultrasound tended to decrease the storage modulus and complex viscosity. Universal tensile test indicated that superior tensile strength occurred in samples containing OMMT layers.

Abstract:
A number of mixing parameters including mixing temperature, rotor speed, fill factor, mixing time, and loading sequence have strong influences on mixing quality. In this work, an in-house developed co-rotating batch mixer equipped with the MX2 rotors, which providing a combination of shear and extensional flows, was used to prepare NR/EPDM blends under various mixing temperatures, rotor speeds, and mixing times. Phase morphology and magnitude of coefficient of dispersive mixing (CDM) were used as qualitative and quantitative determination of mixing quality, respectively. It was found that the lower the mixing temperature, the greater the mixing quality would be obtained. The optimum rotor speed was observed at 60 rpm which was probably caused by the counter-balancing effect of shear stress and shear heating.

Abstract:
AbstractEffects of unmodified halloysite nanotubes (HNTs) and hexadecyl trimethyl ammonnium bromide treated halloysite nanotubes (CTAB-HNTs) on the morphology as well as the thermal and rheological properties of the HNT-filled polypropylene (PP) composites were investigated. The composites were melt-blended with a novel vane mixer dominated by extensional deformation. Fourier transform infrared spectroscopy well demonstrated that ammonium molecules were successfully interacted with halloysite groups. Compared with unmodified HNTs, the modified HNTs had a better dispersion in the PP matrix. The degree of crystallinity increased with the introduction of HNTs into the PP matrix. Thermal analyses revealed that CTAB-HNTs can improve the composites’ thermal stability compared with unmodified HNTs. As for dynamic shear rheology, the PP/CTAB-HNT composites showed higher viscoelaticity than neat PP in most frequency regimes, and that the raw HNT/PP composites presented the opposite phenomenon. The relaxation time of PP melt and the availability of heterogeneous PP domains increased with the presence of CTAB-HNTs.

Abstract:
This research effort is concerned with a class of mathematical programming problems referred to as Mixed-Integer Bilinear Programming Problems. This class of problems, which arises in production, location-allocation, and distribution-application contexts, may be considered as a discrete version of the well-known Bilinear Programming Problem in that one set of decision variables is restricted to be binary valued. The structure of this problem is studied, and special cases wherein it is readily solvable are identified. For the more general case, a new linearization technique is introduced and demonstrated to lead to a tighter linear programming relaxation than obtained through available linearization methods. Based on this linearization, a composite Lagrangian relaxation-implicit enumeration-cutting plane algorithm is developed. Extensive computational experience is provided to test the efficiency of various algorithmic strategies and the effects of problem data on the computational effort of the proposed algorithm. The solution strategy developed for the Mixed-Integer Bilinear Programming Problem may be applied, with suitable modifications,. to other classes of mathematical programming problems: in particular, to the Zero-One Quadratic Programming Problem. In what may be considered as an extension to the work performed on the Mixed-Integer Bilinear Programming Problem, a solution strategy based on an equivalent linear reformulation is developed for the Zero-One Quadratic Programming Problem. The strategy is essentially an implicit enumeration algorithm which employs Lagrangian relaxation, Benders' cutting planes, and local explorations. Computational experience for this problem class is provided to justify the worth of the proposed linear reformulation and algorithm.

Abstract:
Sorting out data into partitions is increasing becoming complex as the constituents of data is growing outward everyday. Mixed data comprises continuous, categorical, directional functional and other types of variables. Clustering mixed data is based on special dissimilarities of the variables. Some data types may influence the clustering solution. Assigning appropriate weight to the functional data may improve the performance of the clustering algorithm. In this paper we use the extension of the Gower coefficient with judciously chosen weight for the L2 to cluster mixed data.The benefits of weighting are demonstrated both in in applications to the Buoy data set as well simulation studies. Our studies show that clustering algorithms with application of proper weight give superior recovery level when a set of data with mixed continuous, categorical directional and functional attributes is clustered. We discuss open problems for future research in clustering mixed data.

Knowledge Discovery in Databases (KDD) is gaining importance with the rising amount of data being collected lately, despite this analytic software systems often provide only the basic and most used procedures and algorithms. The aim of this thesis is to extend RapidMiner, one of the most frequently used systems, with some new procedures for data preprocessing. To understand and develop the procedures, it is important to be acquainted with the KDD, with emphasis on the data preparation phase. It's also important to describe the analytical procedures themselves. To be able to develop an extention for Rapidminer, its needed to get acquainted with the process of creating the extention and the tools that are used. Finally, the resulting extension is introduced and tested.

Abstract:
A large-scale transition to renewable energy sources will become increasingly appealing as the issues of federal regulation, climate change, and decreased fossil fuel energy return on energy investment become more prevalent. Although renewable resources remain a small portion of the nation’s and Utah’s energy portfolio mix, current power purchase agreements indicate an impending boom. Cooperative Extension should play an integral role in the transition to renewable resources on the national, state, and local levels. The purpose of Extension is to provide objective, research-based, and credible information to improve local communities. There is a great opportunity for Extension agents to be trusted experts in educating and assisting farmers, ranchers, and homeowners in transitioning to renewable energy systems. This thesis identified the benefits, barriers, and opportunities for renewable energy outreach in Extension. Data were collected through a nationwide online survey and focus group interviews, in addition to a Utah-based online survey. The nationwide survey and interviews revealed a need and demand for increased renewable energy programming in Extension. This need became further evident after a nationwide inventory discovered that only twenty-two of fifty states have distinct renewable energy departments, programs, or discipline areas. A Utah-based needs assessment revealed that fifty-nine percent of Utah State University (USU) Extension employees agreed that there was a need for a statewide renewable energy specialist. Additionally, more than fifty-five percent of employees agreed that there was an internal and public demand for USU Extension to provide and receive renewable energy information, programs, education, and outreach. The Utah-based survey also revealed differing perceptions of the environmental harmfulness of common energy sources. Different attitudes toward conventional and renewable energy sources demonstrated the need for unbiased, properly messaged delivery of desired renewable energy programs.

Abstract:
Farm to School is a program that connects local and regional foods and other farm products to school meals, develops school gardens, and develops other types of Farm to School experiential learning programs for K-12 students. Since Farm to School began in the mid-1990\'s, Farm to School programs have been developed in all 50 states and Washington D.C. The National Farm to School Network has estimated that almost 12,500 schools are involved with Farm to School, and that during the 2011-2012 school year, 5.7 million students were reached through Farm to School programs and activities. Research to date investigating Farm to School has primarily focused on food system and school system stakeholders including school nutrition directors, food distributors, farmers, school teachers, students, and principals. Not as much research has explored Cooperative Extension\'s role in Farm to School. Farm to School programs are one method for Extension professionals to support community food system development while addressing pressing social concerns related to agricultural viability and public health. Drawing on reasoned action theory and social movement theory, the purpose of this study was to explore food system change through an analysis of Cooperative Extension\'s role in the Farm to School movement. In this two-phase explanatory sequential mixed methods research study, the behavioral intentions/behaviors of Cooperative Extension professionals were analyzed. Additionally, the goals, strategies, and knowledge production of Cooperative Extension professionals participating in the Farm to School movement were explored. Data were collected through an online survey distributed to Extension professionals in eight states. A total of 931 Extension professionals completed the questionnaire resulting in a 48 percent response rate. Data were also collected through a state-based case study that explored Ohio State University (OSU) Extension involvement and leadership in the Ohio Farm to School Program. The case study included 21 interviews with OSU Extension professionals and Farm to School program partners. Regression models were developed to explore which behavioral intentions are statistically significant in explaining Extension participation in the Farm to School movement. Results show that past participation in a Farm to School training program, knowledge about Farm to School, attitude towards Farm to School, perceived social norms towards Farm to School, and perceived behavioral control towards Farm to School are positively associated with participation in the Farm to School movement. Drawing on Stevenson, Ruhf, Lezberg, and Clancy (2007), qualitative analysis found that OSU Extension professional\'s goals for the Farm to School movement were primarily related to food system transformation and inclusion, and their strategies were primarily related to connection. Drawing on Eyerman and Jamison (1991), qualitative analysis also found that OSU Extension professionals were producing primarily organizational knowledge through participation in the Farm to School movement. Additionally, qualitative analysis found that Cooperative Extension Systems are home to several Farm to School movement intellectuals. This study concludes with a discussion of recommendations for Cooperative Extension participation in the Farm to School movement, recommendations for Farm to School program partners, and recommendations for future research in Farm to School.

Abstract:
In chemical processing industries, heating, cooling and other thermal processing of viscous fluids are an integral part of the unit operations. Enhancement of the natural and forced convection heat transfer rates has been the subject of numerous academic and industrial studies. Motionless mixers, also known as static mixers, are often used in continuous mixing, heat transfer, and chemical reactions applications. These mixers have low maintenance and operating costs, low space requirements, and have no moving parts. Heat exchangers equipped with mixing elements are especially well suited for heating or cooling highly viscous fluids. Shell and tube heat exchangers incorporate static mixing elements in the tubes to produce a heat transfer rate significantly higher than that of conventional heat exchangers. The mixing elements continuously create a new interface between the working fluid and tube wall, thereby producing a uniform heat history in the fluid. It is desired to employ motionless mixers in heat transfer applications to provide a high rate of heat transfer from a thermally homogenous fluid with low pressure drop. In the past, laboratory experimentation has been a fundamental part of the design process of a new static mixer for a given application as well as the selection of an existing static mixer. It is possible to use powerful computational fluid dynamics (CFD) tools to study the performance of these mixers without resorting to experimentation. In this paper, which is an extension to the previous work of the authors, the enhancement of performance of shell and tube heat exchangers by inserting motionless mixers (SMX and helical) is studied for creeping, laminar, and low-Re turbulent flows. It is shown that the studied mixers produced similar flow histories for the working fluid considered. Both SMX and helical mixers are able to increase thermal performance of heat exchangers. The SMX mixer manifests a higher performance in temperature blending and in heat transfer enhancement compared to the helical mixer. However, the pressure drop created by SMX elements, and consequently the required energy to maintain the flow in tube, is significantly higher.

Abstract:
In this paper, we study reasoning with existential rules in a setting where some of the predicates may be closed (i.e., their content is fully specified by the data instance) and the remaining open predicates are interpreted under active-domain semantics. We show, unsurprisingly, that the main reasoning tasks (satisfiability and certainty / possibility of Boolean queries) are all intractable in data complexity in the general case. However, several positive (PTIME data) results are obtained for the linear fragment, and interestingly, these tractability results hold also for various extensions, e.g., with negated closed atoms and disjunctive rule heads. This motivates us to take a closer look at the linear fragment, exploring its expressivity and defining a fixpoint extension to approximate non-linear rules.

Abstract:
Abstract Laizhouwan sag in Bohai Bay basin is a fault basin controlled by extensional fault depression and strike slip pull apart, which is an important oil and gas exploration area in Bohai Bay. Exploration practice shows that the prediction of high quality reservoir is the core problem of exploration in this area. Based on the analysis of drilling, seismic data and structural physical simulation in Laizhouwan depression, this paper analyzes the structural deformation under the stress field of strike slip extensional superposition, and points out the dynamic source controlled sand model in the strike slip extensional superposition area. Firstly, The structural response of "pressure relief settlement, pressure boosting uplift" under the mechanism of strike slip extension stress superposition stress is the root cause of block uplift drop alternation transformation. As a result, the southern slope zone of Laizhouwan depression shows the structural pattern of early uplift and late uplift in the East and early uplift and late uplift in the west, forming a "seesaw" structural evolution pattern. Secondly, the unique paleogeomorphology controls the orderly distribution of sedimentary system in time and space. In the Paleocene, the east uplifted, forming a local provenance system. In the denudation area above the slope break developed fracture weathering shell type reservoirs, and the subsidence area under the slope break developed fan delta deposits; In the early Eocene, the relatively flat platform palaeogeomorphology was developed, which created favorable conditions for the development of mixed sedimentary body of lacustrine carbonate and delta; At the end of Eocene, the West was pressurized and uplifted, the East was released and subsided, and the braided river delta sediments of Western provenance were developed. Under the guidance of this recognition, the hidden dynamic provenance was successfully identified in the study area.

Abstract:
This field report provides detailed information on the methodological approach as well as on the process of data collection and analysis in EIWO project III – “Mechanisms and Origins of Late Working Life Exclusion”. EIWO project III is part of the qualitative part of the EIWO programme and is – together with EIWO project VI, VII, and VIII from phase II – one of the four projects in which primary data is collected. EIWO uses a mixed-methods approach in its nine sub-projects, so that quantitative and qualitative methods are used in combination to investigate – from a life course perspective – the topic of late working life and the potential of extension of working lives on different levels (micro, meso and macro level). Due to the different methodological approaches, results from some projects provide evidence for further investigations in other sub-projects, whereby, for example, results of the qualitative investigations can be validated using large data sets. In projects in the field of life course research, a mixed-methods approach is widely used because it allows for a detailed investigation of the structural, institutional and individual factors influencing the life course. EIWO project III focuses in particular on the micro level by taking the perspective of individuals and thus provides a basis on which quantitative analyses, e.g. in EIWO project IV, can be built on. “The main aims of project III are to analyse the nature and sources of inequalities in late working life employment/retirement and to identify individual/family responses and coping strategies” (Application EIWO programme). Based on these aims, the following research questions were formulated for EIWO project III: What events and circumstances can be identified over the life course that lead to social inequalities/exclusion in late working life employment from the individual perspective? What are the explanatory mechanisms? How are exclusion risks and inequalities assessed on the individual level in late working life? Do persons experience social inequalities/exclusion? If they experience exclusion/inequalities: What coping strategies are/were used to reduce inequalities/exclusion? What can be learned from individual responses as to how meso-level organisational policies and macro-level social policies help or hinder transitions? In the following, it will be described why a qualitative research approach was chosen for this project and what characterises this approach. Then, the research instruments and the inclusion criteria for the sample will be explained. The third chapter illustrates the field phase, including the recruitment phase, the final composition of the sample and the conduct of the interviews, as well as challenges that arose during the field phase and the chosen approaches. Finally, the data analysis method is discussed and the report is concluded with a short summary.
