Analysis of residual stresses in laser trimmed alumina microelectronic substrates
… of the substrates while the substrates were trimmed with a 400 watt YAG laser. The substrates were characterized using optical microscopy, scanning electron microscopy / energy dispersive x-ray analysis (SEM/EDAX), electron probe microanalysis (EPMA) and electron spectroscopy for chemical …

Creation of a Trimmed Powered Aerodynamic Database for a Generic Hypersonic Vehicle
… evaluate a methodology for creating an inviscid trimmed powered database for a generic airbreathing hypersonic vehicle. The database was created using the cartesian flow solver Cart3D. Propulsion effects were coupled to the airframe and inlet by using conditions at the inlet of the combustor to …

An optimal approach to geometric trimming of B-spline surfaces
… providing a new mathematical description for the trimmed patch. This entails creating a new geometry for the trimmed patch, which closely approximates the corresponding portion on the original patch. The procedure is shown to involve obtaining data points on the B-spline surface that lie within …

The performance and robustness of confidence intervals for the median of a symmetric distribution constructed assuming sampling from a Cauchy distribution
Trimmed means are robust estimators of location for distributions having heavy tails. Theory and simulation indicate that little efficiency is lost under normality when using appropriately trimmed means and that their use with data from distributions with heavy tails can result in improved …

Cheeseweed (Malva Parviflora L.) Competition with Cabbage and Lettuce on Maui, Hawaii
… in 42 to 49 days. At harvest cabbages were trimmed to two wrapper leaves and weighed. Final weed densities and weed fresh weights were recorded. Curvilinear and linear relationships between trimmed cabbage fresh weight and weed density were defined by regression equations. Regression …

The development of a fixed wing aircraft analysis and design flight dynamic software
… the estimation of aerodynamic characteristics, trimmed flight, stability analysis through linearized approach as well as non-linearized, and finally the control design of the flying behavior by using PID controller method. The estimation of aerodynamic characteristics used the semi-empirical …

The Effects of Beak Trimming and Claw Reduction on Growing and Early Laying Parameters, Fearfulness, and Heterophil to Lymphocyte Ratios
… technique (1-day), one-third were precision trimmed at 7 d of age (7-day), and one-third were not trimmed (IB). Body weight, weight gain, feed intake, feed conversion, mortality, and fearfulness were measured. Rearing followed standard commercial feeding and husbandry procedures. During the …

Geometric trimming of B-spline surfaces
… resemble the original surface which is being trimmed. However, since the entire procedure involves the creation of a new geometry, the resulting surface will not, in general, be identical with the remaining portion of the original one. For this reason, a means to measure the error in …

Medidas de localización robusta para elementos aleatorios con valores imprecisos
… approaches with real/vectorial data: the trimmed means and the M-estimators. To develop or adapt these approaches, two methodologies will be considered, namely: - On one hand, imprecise data can be represented as functional data from (a convex cone within) certain Hilbert space-valued …

Robust Regression Methods For Massively Decayed Intelligence Data
… techniques (ordinary least squares, least-trimmed, and maximum likelihood) were tested against different data decay models presumed to be found in homeland security research studies in order to test whether these techniques will preserve the Type I error rate in the t-test of standardized …

Robust estimation, regression and ranking with applications in portfolio optimization
… problem is often formulated as the least trimmed squares (LTS) regression problem where we want to nd the best subset of observations with the smallest sum of squared residuals. We show the LTS problem is equivalent to a concave minimization problem, which is very hard to solve. We resolve …

Mechanical stress and stress compensation in Hall sensors
… and linear sensing. Although a sensor can be trimmed over temperature before it is shipped to the customer, little can be done about the sensitivity's stability once the sensor has been installed in its final application. The goal of this project is to propose and implement mechanisms to …

A study of factors that influence growth performance and carcass and meat quality of iberian pigs reared under intensive management systems : Estudio de los factores que influyen sobre la productividad y la calidad de la canal y la carne de cerdo Ibérico en intensivo
… carcasses from CF and CM (P<0.001). However, trimmed ham (18.2 vs. 16.8 and 17.2%), trimmed shoulder (11.6 vs. 10.9 and 10.9%) and untrimmed loin (4.0 vs. 3.5 and 3.6%) yield was higher (P<0.001) for IF than for CF and CM. Gender did not affect ham weight losses during ripening, meat chemical …

Benchmarking U.S. beef retail cut composition
… Nutrient Database encompasses only retail cuts trimmed to 1.25 cm, 0.6 cm, 0.3 cm, and 0.0 cm. Cuts from this study consistently had fat thickness measurements between 0.0 cm and 0.3 cm; thus, there is no nutritional information in the Nutrient Database for beef cuts trimmed to these levels.

Sparsity and robustness in modern statistical estimation
… sparse modeling come together by focusing on the trimmed Lasso, a penalization approach to the best subset selection problem. We also contextualize the trimmed Lasso within the broader penalty methods literature by characterizing the relationship with usual separable penalty approaches; as a …

Optimal Geometric Trimming of B-spline Surfaces for Aircraft Design
… is provided to improve the accuracy. The surface trimmed by a closed trimming curve is subdivided into four patches and the trimming curve is converted into two open trimming curves. Two surface patches are created by knot insertion, which match the original surface exactly. The other two surface …

The Effect of Management on Erosion of Civil War Battlefield Earthworks
… burned, mowed, park-forest, forested, or trimmed, best minimized soil erosion. A secondary objective was to determine how several empirical formulas (e.g. Universal Soil Loss Equation) and one field estimate (e.g. erosion pins) compared soil erosion trends for the 5 treatments. A third …

Integrating supplemental lift devices to improve performance in high speed multi rotor UAVs
… a wide angle-of-attack sweep in order to find a trimmed solution. A controller-based approach was used to solve for trimmed conditions, offering flexibility and faster CFD run times. Informed by Latin Hypercube Sampling to explore the design space efficiently, a series of mission-specific design …

Causal Analysis of Disengagement Among Paid and Volunteer City Employees
… but its fit was unsatisfactory. Finally, a trimmed model which included just six outcome variables and 24 paths fit the paid worker data at Q =.77 and the volunteer data at Q =.80. No general conclusions about the validity of the trimmed model can be made prior to cross validation. The …
