BACKGROUND Freeze-drying sperm has been developed as a new preservation method where liquid nitrogen is no longer necessary. An advantage of freeze-drying sperm is that it can be stored at 4 °C and transported at room temperature. Although the successful freeze-drying of sperm has been reported in a number of animals, the possibility of long-term preservation using this method has not yet been ...

Abstract In this paper, cordierite-based porous ceramics with magnetic properties have been firstly in-situ synthesized by using MgO, Al 2 O 3 , and SiO powders as raw materials Fe 4 a functional additive. Combining the foam freeze casting method, near net size fabrication (total linear shrinkage < 2.86%) of was realized adjusting amount . The porosity, compressive strength, saturation magne...

The method devised by Lewis et al. (1993) for calculating the light curve of a microlensed point source is expanded to two dimensions to enable the calculation of light curves of extended sources. This method is significantly faster than the ray shooting method that has been used in the past. The increased efficiency is used to obtain much higher resolution light curves over increased time scal...

This work further elaborates on the steel plant MILP production scheduling method presented in Harjunkoski and Grossmann (2001). The proposed improvements include a more flexible model for the casting step, as well as combining orders from consecutive weeks to improve one of the main targets, which is increasing the number of heats per casting sequence. The paper presents a strategy to obtain o...

In this paper, we propose an automated visual inspection method for casting defects. Automatic inspection systems have the potential to significantly improve quality and increase production rates. In our method, the contour discontinuity of casting product and machine-learning-based defect detection are utilized to detect defects on the surface of products. The peripheral vision and involuntary...
