Summary: By simulation and verification experiments, the process parameters were optimized to reduce the tendency of significant shrinkage porosity in the centrifugal cast ring parts of K417 nickel-based superalloy. The centrifuge speed and mold preheating temperature have the greatest influence on the shrinkage porosity ratio, while the pouring temperature and pouring speed have relatively small effects. The optimized parameters effectively reduce the formation of shrinkage porosity in the K417 centrifugal casting rings.

Summary: The present study aims to investigate the drying kinetics and obtain the optimum process parameters of cantaloupe slices using short-and medium-wave infrared radiation (SMIR) drying technology. The results showed that infrared radiation temperature and slice thickness had significant effects on the L value and color difference (△E), while hardness and vitamin C content were significantly affected by infrared radiation temperature, slice thickness, and radiation distance. The optimum drying parameters were determined to maximize vitamin C content and L value, and minimize △E and hardness value. The experimental values under the optimum drying conditions were in accordance with the expected values. This study is of great importance for the development of the cantaloupe food processing industry and the application of SMIR drying technology to improve drying rate and product quality.

Summary: This study examines the influence of process variables, such as curing temperature and relative humidity (RH), on the shrinkage of alkali-activated fly ash (AAF). Analysis shows that the strength and pore structure formed in the AAF are dependent on the sodium alumino-silicate (N-A-S-H) gel content, which is sensitive to moisture availability. Reduction in temperature and RH after initial accelerated curing has a beneficial effect on reducing shrinkage compared to drying at a higher temperature. The shrinkage in AAF is significantly lower than a comparable cement paste, and is primarily influenced by the pore structure formed and the N-A-S-H content.

Summary: This paper proposes a method that can optimize the luminance, contrast, and color difference of remote-sensing images. By processing the chrominance and luminance channels of the image in the YCbCr color space, it reduces the influence of different channels. The proposed method has been tested on challenging datasets and shows better results than state-of-the-art approaches in terms of visuals and quality indicators.

Summary: The objective of this study was to compare the quality of low-acid vegetables conventionally thermal processed with those subjected to modified thermal processing following acidification to pH < 4.6. The acidified thermal processing yielded significantly better retained color and textural properties, almost similar to blanched vegetables, while those subjected to the conventional processing resulted in significant texture loss. The acidified thermal process provided significant energy saving opportunities and had a positive potential for quality retention, energy savings, and process efficiency.

Summary: This study investigated the changes in viscoelastic properties and physical qualities of Chinese yams during multiphase microwave drying (MMD) and analyzed their intrinsic relationship. The results showed that the rehydration ratio (RR), volume ratio (Vr), and porosity increased and then decreased with drying time during MMD. The highest microwave power in sublimation drying resulted in the lowest RR, Vr, and porosity but the highest hardness. The Maxwell model successfully described the viscoelastic behaviors of yams. The enhanced stress relaxation behavior was observed during sublimation drying. Pearson's correlation analysis showed significant relationships between relaxation modulus and RR, porosity, hardness, and brittleness. Principal component regression models explained the relationships between the viscoelastic indexes and physical features well.

Summary: This paper proposes a new microscale microsegregation evaluation method based on the concept of degree centrality in network science, and investigates the impact of different holding times and temperatures on the porosity microsegregation in continuous casting bloom for heavy rail steel. The results show that the holding temperature has the greatest influence on element diffusion, and when the size of the shrinkage cavity is greater than 400 μm, the optimal holding temperature is 1250 °C, and the optimal holding time is 90 min. The new diffusion kinetic model of porosity microsegregation has high accuracy under the optimal conditions of the heating process.

Summary: Shrinkage porosity is a common defect in high-pressure die-casting (HPDC), caused by the solidification and subsequent shrinkage of the metal. This study investigates the effects of process parameters and part geometry on shrinkage defects in HPDC. By examining different casting models under various casting conditions, we identify the influence of molten metal injection temperature and injection speed, as well as the predominant role of casting geometry. Prediction and verification of shrinkage defects are performed using secondary dendrite arm spacing and the Niyama criteria, with a clear correlation between processing parameters and shrinkage in a specific geometry established.

Summary: The research on EHD drying focused on designing multiple-emitter discharge electrodes by optimizing emitter type and arrangement, with emitters made of construction nails and thin pins showing the best performance. Evaluating drying efficiency through drying rate and specific energy consumption (SEC), the nail electrode with a square arrangement demonstrated the highest efficiency. Increasing electric field strength or gap between electrodes led to higher drying rates and SEC, while the chess arrangement reduced drying rate without affecting SEC.
