Interaction involves people communicating and reacting to each other. This process is key to the study of discourse, but it is not easy to study systematically how interaction takes place in a specific communicative event, or how it is typically performed over a series of repeated communicative events. However, with a written record of the interaction, it becomes possible to study the process in some detail. This thesis investigates interaction through asynchronous written discussion forums in a computer-mediated learning environment. In particular, this study investigates pragmatic aspects of the communicative event which the asynchronous online discussions comprise. The first case study examines response patterns to messages by looking at the content of initial messages and responses, in order to determine the extent to which characteristics of the messages themselves or other situational factors affect the interaction. The second study examines in what ways participants use a range of discourse devices, including formulaic politeness, humour and supportive feedback as community building strategies in the interaction. The third study investigates the role of the subject line of messages in the interaction, for example by examining how participants choose different types of subject lines for different types of messages. The fourth study examines to what extent features serving a deictic function are drawn on in the interaction and then compares the findings to both oral conversation and formal academic discourse. The overall findings show a complex communicative situation shaped by the medium itself, type of activity, the academic discipline and topic of discussion and by the social and cultural aspects of tertiary education in an online learning environment. In addition, the findings may also provide evidence of learning. / The four case studies presented in Language and interaction in online asynchronous communication in university level English courses investigate written discussion forum interaction in a computer-mediated learning environment. These studies deal with different, yet related, aspects of discussion forum communication. Aspects included are the labeling and response patterns of messages, community-building strategies among participants and features of informal conversation and formal academic writing in the messages. Building on discourse analysis combined with content analysis and corpus method, the work systematically examines the linguistic patterns of communication in the discussion forums. The findings show that there are multiple factors at work simultaneously that affect the linguistic choices by the discourse participants. The constraints and opportunities of the communication are not only connected to the fact that it is computer-mediated, but also to the fact that it is written and in a particular academic environment. Knowledge of the choices available and of what factors potentially affect them is useful for anybody involved in research on net-based teaching and learning.

Significant proportion of composite industry is currently produced using prepregs, cured in autoclave which is very expensive and time consuming process. Dry textile preforms in conjunction with liquid molding techniques can lead to significant reductions in material costs, manufacturing costs and cycle times. These dry preforms are typically 2D woven or braided fabrics which also required lay-up and have low interlaminar properties. Through thickness reinforcement provides solution for this problem as it gives better interlaminar properties as well as near net shape performing. Various 3D performing methods are discussed and reviewed in this research where 3D weaving comes out as ideal process to develop near net shape preforms with more efficiency and better material performance. This research highlights the advantages and limitations of conventional 3D weaving processes. A number of approaches for improving the flexibility of 3D weaving process have been presented including changing fiber architecture in different sections of the preform, tapering in the width and thickness directions and finally to change the fiber orientation. It is concluded that multi step and taper fabrics can be produced on conventional weaving by some modifications. Furthermore, a novel 3D weaving machine is designed and developed after reviewing various patents and weaving methods to overcome limitations of conventional weaving machine. Key criterions from limitations of conventional weaving processes are considered and modified such as multiple weft insertion, limited warp stuffer movement, linear take-up to develop 3D weaving machine. In order to achieve isotropic material, two textile technologies are combined to get final requirements. 3D weaving can provide us fibres in 0° and 90° direction with through thickness reinforcement, whereas braiding can satisfy the requirement of bias direction fibres. Near net shape preforms such as taper and multistep are produced and laminated. Preliminary testing is performed on these laminates to evaluate fibre architectures. Further work is required in terms of machine modification which can provide weave design flexibility to explore various multilayer weave architectures. Thorough testing is required to evaluate and define structure performance and effect of fibre damage during weaving process.

In this diploma thesis the author will elaborate on asynchronous and parallel programming in the .NET framework version 4 and version 4.5. The aim of this thesis will be to prove and provide better insight on the task-programming model that Microsoft introduced and compare different applications in terms of speed and lines of code used to write then and the differences between them using simple statistics. Using the literature gathered, the author will explain what would be the best ways to achieve parallelism on applications, write about design patterns used, and provide code snippets that will help the reader get better overall understanding of the Task Parallel Library and the benefits it gives in comparison of older methods and sequential programming.

AN ABSTRACT OF THE THESIS OF Rohit Kadam, for the Master of Science degree in MECHANICAL ENGINEERING, presented on DECEMBER 2, 2011, at Southern Illinois University Carbondale. (Do not use abbreviations.) TITLE: NET ZERO BUILIND ENERGY CONSERVATION MAJOR PROFESSOR: Dr. Emmanuel Nsofor This research deals with energy studies performed as part of a net-zero energy study for buildings. Measured data of actual energy utilization by a building for a continuous period of 33 months was collected and studied. The peak design day on which the building consumes maximum energy was found. The averages of the energy consumption for the peak month were determined. The DOE EnergyPlus software was used to simulate the energy requirements for the building and also obtain peak energy requirements for the peak month. Alternative energy sources such as ground source heat pump, solar photovoltaic (PV) panels and day-lighting modifications were applied to redesign the energy consumption for the building towards meeting net-zero energy requirements. The present energy use by the building, DOE Energy software simulations for the building as well as the net-zero model for the building were studied. The extents of the contributions of the individual energy harvesting measures were studied. For meeting Net Zero Energy requirement, it was found that the total energy load for the building can be distributed between alternative energy methods as 5.4% to daylighting modifications, 58% to geothermal and 36.6% to solar photovoltaic panels for electricity supply and thermal energy. Thus the directions to proceed towards achieving complete net-zero energy status were identified.

La modélisation des préférences par le biais de formalismes de représentation compacte fait l'objet de travaux soutenus en intelligence artificielle depuis plus d'une quinzaine d'années. Ces formalismes permettent l'expression de modèles suffisamment flexibles et riches pour décrire des comportements de décision complexes. Pour être intéressants en pratique, ces formalismes doivent de plus permettre l'élicitation des préférences de l'utilisateur, et ce en restant à un niveau admissible d'interaction. La configuration de produits combinatoires dans sa version business to customer et la recherche à base de préférences constituent de bons exemples de ce type de problème de décision où les préférences de l'utilisateur ne sont pas connues a priori. Dans un premier temps, nous nous sommes penchés sur l'apprentissage de GAI-décompositions. Nous verrons qu'il est possible d'apprendre une telle représentation en temps polynomial en passant par un système d'inéquations linéaires. Dans un second temps, nous proposerons une version probabiliste des CP-nets permettant la représentation de préférences multi-utilisateurs afin de réduire le temps nécessaire à l'apprentissage des préférences d'un utilisateur. Nous étudierons les différentes requêtes que l'on peut utiliser avec une telle représentation, puis nous nous pencherons sur la complexité de ces requêtes. Enfin, nous verrons comment apprendre ce nouveau formalisme, soit grâce à un apprentissage hors ligne à partir d'un ensemble d'objets optimaux, soit grâce à un apprentissage en ligne à partir d'un ensemble de questions posées à l'utilisateur. / --

Master of Agribusiness / Department of Agricultural Economics / Allen M. Featherstone / Johnsonville Sausage is a privately held company based in Sheboygan Falls, WI. The company has a growing cooked sausage business and is evaluating options to expand capacity. Investing in either of two existing facilities or outsourcing production to a co-manufacturer is being considered in this make versus buy analysis. Intense competition in the category and uncertain raw material markets are considerations in the evaluation. Data used for the analyses were obtained from Johnsonville sources. Assumptions for the “make” analyses were based on existing data where applicable such as labor and utilities, and in other cases assumptions were made based on company knowledge of the process. Johnsonville engineers worked closely with equipment vendors to develop the building and equipment investment plan. Data for the “buy” alternative were received from a prequalified co-packer with advanced manufacturing technology. A Net Present Value (NPV) model is developed for each alternative and used to determine financial viability of each. The models consider varying investment requirements, freight rates and cost of goods for each alternative. Sensitivity analyses are performed to address key variables such as raw material prices and sales volume. The paper concludes that investment in Sheboygan is a viable option; however, the investment poses risk if raw material prices rise and or volume declines from expected projections. Therefore, the recommendation is to outsource production and initiate the Sheboygan project when the co-packed volume reaches 15 million pounds.

Master of Agribusiness / Department of Agricultural Economics / Kevin Dhuyvetter / Many companies use surveys to establish customer satisfaction metrics. This OEM has been using surveys to analyze customer satisfaction with their products, services, and distribution channel for several decades. Satisfaction metrics are established for the brand, product, and channel partners. The product metric is derived from a question on the survey asking customers how satisfied they are with the product. There are subsequent questions thereafter inquiring about satisfaction with specific functional areas of the product. It is common practice to use Partial Least Squares (PLS) regression analysis to evaluate what impacts the functional area questions have on the overall satisfaction question. The model results are used to understand what areas of the machine should be focused on to improve customers’ experiences with the machine. These results are compared to other data sources such as warranty, field reports, customer focus groups, etc. The results from these models are sometimes questioned based on what common intuition would suggest. Typically the top three drivers to the product metric are understandable, but there are often one or two key areas that do not make logical sense. The objective of this thesis was to understand whether PLS modeling is appropriate given the nature of customer survey data. Models were estimated using existing survey data on a specific model in the tractor product line. PLS models assume data are linear with no bounds. This in itself likely makes this type of model inappropriate for analyzing customer survey data. Responses are bounded on an 11 point scale from 0-10, however, the PLS model being non-bounded assumes there can be a score under 0 or over 10. The model also assumes a linear slope that would indicate each covariate answer 0-10 has the same level of effect on the response variable. This research has found that each covariate answer is in fact non-linear. For example, a customer answering a 2 to quality of manufacturing workmanship has a different impact on the overall satisfaction score than a customer who answers 8. Finally, this research discovered that the PLS models produce negative coefficients of significant value that are not reported to the enterprise. Binary and ordered logistic (logit) models were estimated as an alternative to PLS. Logistic models are non-linear and are commonly used to evaluate bounded data. Response data were separated into two groups based on Net Promoter Score (NPS) Methodology (Reicheld 2006). Using the NPS methodology, 0-6 scores are considered detractors, 7-8 scores are considered passives, and 9-10 scores are considered promoters. The logistic models demonstrate that the top two drivers to customer satisfaction scores are still quality of manufacturing workmanship and reliability/operational availability (similar to results of the PLS model). The unresolved problems question on the survey was included in the models and demonstrated that the predicted probability of a customer being a promoter is much higher in both binary and ordered logit models if no unresolved problems exist. Finally, the model found engine oil consumption remained negative and is statistically significant suggesting that even with the alternative modeling approach there still may be data issues related to the survey. It is recommended that the OEM implement logistic modeling for analyzing customer survey data. It is also recommended that a new survey design be constructed to eliminate issues with correlated data that can lead to spurious and unexplainable results.
