Model Calibration and Performance Optimization Using Multiple-Point Geostatistics and Machine Learning Techniques
… integration method, which employs the power of multiple-point geostatistics (MPS), to match production data while being constrained to other reservoir data including prior geological information. Using the PPM, one can systematically perturb a spatial distribution of reservoir properties while …

Secondary Level Screening of Chlamydomonas Reinhardtii Mutants Defective in Circadian Gene Expression
… mutants were selected based on aberrant single-point accumulative arylsulfatase activity. In this study, the arylsulfatase activity over the entire growth cycle was further investigated in these mutants and the reliability of the single-point screen was assessed. Of the 16 strains whose …

The Campfire's Glow
… memos, and other documents found at camp. This multiple point of view approach helps to build the characters and give a sense of the texture of life at camp.

Study of Turbulent Structure Close to a Wall Using Conditional Sampling Techniques
… and at different times in its development. Using multiple-point measurements and conditional sampling methods both the kinematics and the dynamics of the wall eddies could be studied. The axial and spanwise velocity components in the fluid were measured by a hot-film X-probe.

A Multi-Point Measurement Technique for the Enhancement of Force Measurement with Active Magnetic Bearings (AMB)
… for measuring forces with AMBs that utilizes multiple current pairs with no gap measurement to provide accurate and precise force predictions. Previous methods for force measurement with AMBs rely on the controlled environment of a laboratory setting for accurate measurements. The goal of this …

Structural Design of a Crashworthy Energy Absorbing Passenger Seat For a Large Transport Aircraft Using Large Displacement, Nonlinear Material Finite Element Analysis
… algorithm. This algorithm did not converge and multiple-point constraints were used to transfer the dummy's inertia load. This approach was validated with the software SOMTA and then used to predict the response of a high energy absorption seat design subjected to the floor deceleration as …

BUILDING A BETTER TRAINING IMAGE WITH DIGITAL OUTCROP MODELS: THESE GO TO ELEVEN
… facies geometries and fluid flow paths. Multiple-point statistics (MPS) has shown promise in portraying complex geometries realistically; however, realizations are limited by the reliability of the model of heterogeneity upon which MPS relies, that is the Training Image (TI). Attempting …

Low energy consequences of some non-standard Higgs models
… in these models. Another idea considered is the multiple point principle (MPP) applied to the two Higgs doublet extension of the Standard Model. The MPP stipulates that the coupling constants will be tuned to allow the existence of a maximal number of degenerate vacua. This principle is shown to …

Design and characterization of a gel loading mechanism for an ultra-high throughput mutational spectrometer
… parallel channels of CDCE in order to correlate multiple point mutations in DNA with the diseases that they can cause, such as cancer. By separating the DNA in large populations, the underlying causes of such diseases can be identified. To successfully run CDCE, a high viscosity polymer gel must …

IP multicast video with smart network caches
… data throughput, and reliability in a multi-point distribution environment. At the same time, there are the possibilities for more interaction and cooperative sharing of contents amongst hosts on the network. IP multicast addresses the bandwidth scalability issue by providing an efficient …

Air pollution modelling for the greater Cape Town region
… the pollution simulation. The model requires one point meteorological measurements and can accommodate multiple point, line and area sources. Meteorological data used in the study were collected from D. F. Malan airport for the years 1991 and 1992. However, required parameters, such as the mixing …

Design and transformation of three dimensional pupils : diffractive and subwavelength
… to design further, more sophisticated point spread functions which are potentially useful for many imaging purposes. Deformations using multiple point indenters will be investigated in terms of both forward and inverse problems. Bulk transformation is a more general approach for pupil …

Improved robustness formulations and a simulation-based robust concept exploration method
… and introduced to a modified RCEM. The developed Multiple Point Method is based on the Sensitivity Index (SI) and improves the variance estimation in RCEM significantly, especially for nonlinear problems. This approach is applicable to design problems, for which the performance functions are known …

Reinforcement learning based control for arrays of point absorber wave energy converters
… a review of and background material relating to point absorber wave energy converters. These are devices that have small dimensions compared to the incident wavelength, and are axisymmetric in design. In most cases, energy is primarily associated with heave motion. A standard point absorber …

Graded-commutative nonassociative algebras: higher octonions and Krichever-Novikov superalgebras; their structures, combinatorics and non-trivial cocycles.
… a family of Lie algebras with two marked points generalizing the Witt algebra and its central extension called the Virasoro algebra. The K-N Lie (super)algebras for more than two marked points were studied by Schlichenmaier. In particular, he extended the explicit formula of $2$-cocycles …

Multimodal data analysis applied to a medical setting
… the biology of such diseases, joint analysis of multiple data modalities could provide interesting insights. We propose the use of canonical correlation analysis (CCA) as a preliminary discovery tool for identifying connections across modalities, specifically between gene expression and features …

Bug vision : experiments in low resolution vision
Tracking multiple people using cameras is similar to the well-studied problem of tracking multiple radar or sonar echoes. This thesis shows that current camera-based tracking algorithms convert each image in a video sequence to a list of targets through a segmentation step, and pass this target set …
