Lazy TRIM: Optimizing the journaling overhead caused by TRIM commands on Ext4 file system
2018 IEEE International Conference on Consumer Electronics (ICCE), 2018Nowadays, NAND flash storage devices have become a standard for secondary storage in consumer electronics devices. Unfortunately, TRIM command for the flash storage causes journaling overhead on the ext4 file system. In this paper, to figure out the root cause of the overhead, we study the relationship between ordered mode journaling and the TRIM ...

Reachability analysis on optimal trim state for aerial docking
Aerospace Science and Technology, 2021Abstract Aerial refueling is an important capability to increase the endurance and flight range of aircraft, but it often suffers from a low success rate. The altitude and speed of the tanker aircraft in the docking phase play a great role in the docking success rate. According to this, the optimal trim state, namely the optimal speed and altitude of

Aerodynamic design optimization trim analysis of canard conventionalconfigurations
Journal of Aircraft, 1984A design study has been conducted to optimize trim cruise flight of high performance general aviation canard aircraft which achieve minimum drag. In order to investigate the advantages and disadvantages of canard configured aircraft, corresponding conventional tail-aft "baseline" aircraft were designed and used for comparison.

Trim mask optimization for hybrid multiple pattering lithography
2016 International Symposium on VLSI Design, Automation and Test (VLSI-DAT), 2016Due to the delay of next generation lithography technologies, multiple patterning lithography technologies are still the most promising solutions for sub-20nm technology nodes. To enhance pattern printability, one-dimensional grid-based layout structure will be adopted, which can be achieved with a self-aligned multiple patterning (SAMP) process ...

Trimmed Data-Driven Evolutionary Optimization Using Selective Surrogate Ensembles
2021Data-driven evolutionary algorithms (DDEAs) have attracted much attention in recent years, due to their effectiveness and advantages in solving expensive and complex optimization problems. In an offline data-driven evolutionary algorithm, no additional information is available to update surrogate models, so we need to ensure the quality of the ...
