A Mathematical Model for Reduction of Trim Loss in Cutting Reels at a Make-to-Order Paper Mill

open access: yesApplied Sciences, 2020
One of the main issues in a paper mill is the minimization of trim loss when cutting master reels and stocked reels into reels of smaller required widths.

Optimization method and experimental research on attitude adjustment scheme of attitude adaptive rescue robot

open access: yesScientific Reports, 2022
To improve the space attitude adjustment efficiency of the robot designed in this study, the average water level height variation of each ballast tank during the rescue process and the ballast water filling mass before the rescue process are taken as ...

Vessel's trim optimization using IoT data and machine learning models

open access: yes, 2022
The shipping industry is an important source of greenhouse gas emissions, such as carbon dioxide, methane and nitrogen oxides. In the past few years, environmental and policy reasons dictate the immense reduction of greenhouse gas emissions in industries

Trace-Driven Scaling of Microservice Applications

open access: yesIEEE Access, 2023
The containerized microservices architecture is being increasingly used to build complex applications. To minimize operating costs, service providers typically rely on an auto-scaler to “right size” their infrastructure amid fluctuating ...

Experimental and Numerical Trimming Optimizations for a Mainsail in Upwind Conditions [PDF]

open access: yesSNAME 22nd Chesapeake Sailing Yacht Symposium, 2016
This paper investigates the use of meta-models for optimizing sails trimming. A Gaussian process is used to robustly approximate the dependence of the performance with the trimming parameters to be optimized. The Gaussian process construction uses a limited number of performance observations at carefully selected trimming points, potentially enabling ...

Hull Form Optimization Study Based on Multiple Parametric Modification Curves and Free Surface Reynolds-Averaged Navier–Stokes (RANS) Solver

open access: yesApplied Sciences, 2022
In this study, the hull form optimization process to minimize resistance of KCS (KRISO containership) at Fn=0.26 is described. The bow hull form of KCS was modified by varying such design parameters as sectional area curve (SAC), section shape, bulb ...

On choosing an optimally trimmed mean

open access: yesCommunications in Statistics - Simulation and Computation, 1991
In this paper we revisit the problem of choosing an optimally trimmed mean. This problem was originally addressed by Jaeckel (1971). We propose alternatives to Jaeckel's estimator and its modifications discussed in Andrews et al. (1972). Jaeckel's procedure chooses the optimal trimming by minimizing an estimate of the asymptotic variance of the trimmed

Automated Design Optimization of a Mono Tiltrotor in Hovering and Cruising States

open access: yesEnergies, 2020
A mono tiltrotor (MTR) design which combines concepts of a tiltrotor and coaxial rotor is presented. The aerodynamic modeling of the MTR based on blade element momentum theory (BEMT) is conducted, and the method is fully validated with previous ...

Trim Optimizations of an Adaptive Tailless Aircraft with Composite Wing [PDF]

open access: yesAdvanced Materials Research, 2011
This paper investigates aeroelastic tailoring and optimal trailing edge control surface deflection to minimize induced drag for a HALE UAV flying wing configuration. The analysis process is conducted on the Finite Element(FE) model of a composite slender wing. Genetic Algorithm(GA) is employed to aeroelastically tailor the wing by setting the composite

A Grey-box model approach using noon report data for trim optimization

open access: yes, 2023
Trim optimization improves the energy efficiency of ships, thus reducing operational costs and emissions; however, trim tables are only available for a limited number of ships.
