Optimal Block-Based Trimming for Next Generation Sequencing

IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2018
Read trimming is a fundamental first step of the analysis of next generation sequencing (NGS) data. Traditionally, it is performed heuristically, and algorithmic work in this area has been neglected. Here, we address this topic and formulate three optimization problems for block-based trimming (truncating the same low-quality positions at both ends for

Multidisciplinary, Multiobjective Trim Optimization for a Coaxial-Pusher Rotorcraft Configuration

Proceedings of the Vertical Flight Society 75th Annual Forum, 2019
The control redundancy inherent to a coaxial helicopter facilitates multiple achievable configurations for trimmed flight conditions. These redundancies can be exploited to optimize performance across multiple disciplines including the minimization of ...

Predictive Surrogates for Aerodynamic Performance and Independent Sail Trim Optimization of Multiple Wind Propulsion System Configurations

Journal of Sailing Technology
Wind Propulsion Systems (WPS) have gained significant attention as a means of decarbonizing shipping. Limitations in available deck space, emissions reduction targets, and regulatory compliance have led to a wide array of potential WPS configurations,

Optimization of Geometrically Trimmed B-Spline Surfaces

Computers and Information in Engineering, 2005
Unlike the visual trimming of B-spline surfaces, which hides unwanted portions in rendering, the geometric trimming approach provides a mathematically clean representation without redundancy. However, the process may lead to significant deviation from the corresponding portion on the original surface.

Improvement of laser trimmed film resistor stability by selection of optimal trim paths

1991 IEEE International Symposium on Circuits and Systems (ISCAS), 1991
A study comparing post-trim drift performance of laser-trimmed film resistors is presented. The goal was to determine the influence of the following factors on post-trim drift performance: (1) type of trim cuts, (2) initial trim position, (3) laser adjustment parameters, and (4) amount of trim.

Isogeometric shape optimization of trimmed shell structures

Structural and Multidisciplinary Optimization, 2015
In most of structural analyses and optimizations using the conventional isogeometric analysis, handling of trimmed or topologically complex geometries is difficult and awkward. A trimmed or topologically complex geometry is normally modeled with multiple untrimmed patches due to the tensor-product form of a Non-Uniform Rational B-Spline (NURBS) surface,

A Physics-Based Approach to Trim Optimization of Coaxial Helicopters in High-Speed Flight

Proceedings of the Vertical Flight Society 71st Annual Forum, 2015
Optimal trim was investigated for a lift-offset coaxial helicopter in high speed flight. An RCAS model of the XH-59 Advancing Blade Concept demonstrator aircraft was developed for the study and flight test trim conditions at 250 kts were used for ...
