Typically aerospace components produced using the Resin Transfer Molding (RTM) process are required by specification to use very high final injection pressure. This is believed to be necessary to produce a laminate that is void free and that produces structural equivalence to historical autoclave moldings. However, a low pressure RTM process has been developed, tested, and validated that produc...

Learning latent representations is playing a pivotal role in machine learning and many application areas. Previous work on the relational topic model (RTM) has shown promise on learning latent topical representations for describing relational document networks and predicting pairwise links. However under a probabilistic formulation with normalization constraints, RTM could be ineffective in con...

Reverse time migration produces an image by crosscorrelating the solution of the wave equation solved forward in time with the wave equation solved backwards in time. Solution of the wave equation can be computationally prohibitive for large subsurface regions. Therefore one typically combines a finite difference discretization of the wave equation with a parallel computing paradigm such as dom...

Abstract The Representational Theory of Measurement (RTM) is the best known account kind representation measurement requires. However, RTM has been challenged from various angles, with critics claiming e.g. that fails to for actual practice and it ambiguous about nature measurable attributes. In this paper I use critical literature on formulate Representation Minimalism – a characterization wha...

Precipitable water vapor can be estimated from the Global Navigation Satellite System (GNSS) signal’s zenith wet delay (ZWD) by multiplying a conversion factor, which is function of weighted mean temperature (Tm) over GNSS station. Obtaining Tm an important step in precipitable (PWV) conversion. In this study, aiming at problem that affected space and time, observations seven radiosonde station...

Carbon capture and storage (CCS) is a key technology that directly removes industry driven CO2 to achieve carbon neutrality. In the process of CCS, it necessary monitor whether injected properly stored not leaking. The behavior can be investigated using 4D seismic survey compares data before after injection. We proposed two-step monitoring with diffraction-angle filtering (DAF) effectively loca...

We report here a 47-year-old male with the diagnosis of high-grade B-cell lymphoma and hemophagocytosis accompanying disseminated intravascular coagulation (DIC). Lymphoma-associated hemophagocytic syndrome (LAHS) is a life-threatening disorder, and LAHS secondary to B-cell lymphoma is relatively rare compared to that secondary to T- or NK/T-cell lymphoma in Western countries. T- or NK/T-cell L...

In many circumstances, heritability estimates are subject to two potentially interacting pitfalls: the spatial and the regression to the mean (RTM) fallacies. The spatial fallacy occurs when the set of potential movement options differs among individuals according to where individuals depart. The RTM fallacy occurs when extreme measurements are followed by measurements that are closer to the me...

We studied the mechanism of volatile-induced surface porosity formation during the resin transfer molding (RTM) of aerospace composites using a blended benzoxazine/epoxy resin, and identified reduction strategies based on material and processing parameters. The influence of viscosity and pressure on resin volatilization were determined. Then, in situ data was collected during molding using a la...
