Gaussian Process Regression For Virtual Metrology-Enabled Run-To-Run Control In Semiconductor Manufacturing, J Wan, S Mcloone

School of Engineering, Computing and Mathematics

Incorporating virtual metrology (VM) into run-to-run (R2R) control enables the benefits of R2R control to be maintained while avoiding the negative cost and cycle time impacts of actual metrology. Due to the potential for prediction errors from VM models, the prediction as well as the corresponding confidence information on the predictions should be properly considered in VM-enabled R2R control schemes in order to guarantee control performance. This paper proposes the use of Gaussian process regression (GPR) models in VM-enabled R2R control due to their ability to provide this information in an integrated fashion. The mean value of the GPR prediction …

Developing A New Total Sediment Transport Formula, Davut Okeu, Sokol Xhafa, Sevdije Govori, Majlinda Daci

UBT International Conference

Sediment transport is one of the most powerful factor on river hydrology. It has vital importance for water engineering projects. There are many sediment transport formulas in the literature but most of them are derived from small data sets of natural rivers or experimental designs. Each formulation has its own restrictions, which depends on the original dataset of that study. None of them have gained universal acceptance. As a result, investigation towards the development of more accurate and simpler formulae is still necessary and should be continued.

The aim of this study is to derive a new total sediment load …

Towards Secure Data Flow Oriented Multi-Vendor Ict Governance Model, Lars Magnusson, Patrik Elm, Anita Mirijamdotter

UBT International Conference

Today, still, ICT Governance is being regarded as a departmental concern, not an overall organizational concern. History has shown us that implementation strategies, which are based on departments, results in fractional implementations leading to ad hoc solutions with no central control and stagnation for the in-house ICT strategy. Further, this recently has created an opinion trend; many are talking about the ICT department as being redundant, a dying out breed, which should be replaced by on-demand specialized external services. Clearly, the evermore changing surroundings do force organizations to accelerate the pace of new adaptations within their ICT plans, more vivacious …

The Regener-Pfotzer Maxima During A Total Solar Eclipse, Gordon Mcintosh, Liam Taylor, Alaina Swanson, Erick Agrimson, Kaye Smith, Alynie Xiong

2017 Academic High Altitude Conference

The Regener-Pfotzer (RP) maximum is the altitude at which cosmic radiation intensity is the greatest. A reduction of the altitude of the interaction layer, assumed to be measured by the RP maximum, has been suggested to account for a reduction in the secondary cosmic ray flux measured at the surface of the Earth during a total solar eclipse. To investigate this suggestion, high altitude cosmic radiation was measured using Geiger Mueller (GM) counters carried beneath weather balloons both before and during the total solar eclipse on August 21st, 2017. The pre-eclipse omnidirectional RP maxima occurred at an average altitude of …

2017 Academic High Altitude Conference

A thermal wake occurs when a high altitude balloon (HAB) influences and changes the surrounding ambient atmospheric temperature of the air through which it passes. This effect warms the air below the balloon to greater than ambient temperatures during daytime flights, and cooler than ambient temperatures during nighttime flights. The total solar eclipse of August 21^st 2017, provided us with an opportunity to study these balloon induced temperature transitions from daytime, to eclipsed induced night conditions over the time scale of a single flight. To measure these transitions, St. Catherine University and the University of Minnesota, Morris, flew over …

Examining The Learning-By-Teaching Process Through Concept Maps, Lindsey Murry, Michael Hein

River Cities Industrial and Organizational Psychology Conference

While learning-by-teaching has been shown to be effective, research in the area lacks a standardization of measurement and manipulations. Meta-analytic evidence has shown that peer tutoring is an effective learning tool for tutors (Cohen, Kulik, & Kulik, 1982); however, these studies do not provide a way of differentiating the effects of explaining versus interacting with the tutees and answering their questions, thus forcing the tutors to identify their own knowledge gaps. Studies that have experimented with the learning-by-teaching method have found that simply preparing to teach can be more effective than other learning techniques, such as only reading or preparing …

Learning Organization, Its Relationship With Knowledge Performance And Financial Performance, Jeeun Yi

River Cities Industrial and Organizational Psychology Conference

A learning organization has been addressed as a key organizational culture in the current fast-paced global market. However, despite the attention, there was no commonly accepted single model of the learning organization. In this study, recently discussed two alternative models for learning organization and performance were compared in terms of theoretical as well as statistical approaches. One question from the alternatives was related with the dimensionality of learning organization. General one-factor model and two sub-factor models for learning organization were compared. Another question was about financial and knowledge performance which are functioning as a final endogenous variable or a mediator. …
