7results about How to "Efficient and cost-effective" patented technology

The present invention relates to the purification of immunoglobulins and the problem of providing a method for purifying an immunoglobulin in an efficient and cost-effective manner and with satisfactory purity and yield. In particular, the present invention addresses the aspect of the re-use of the rather cost-intensive chromatography materials, in particular the lifetime of the chromatography materials used in the capture step of the downstream process, and how this can be increased while reducing the technical complexity of the purification process.

This invention provides an integrated method for pruning and controlling large-scale models of unmanned aerial vehicles (UAVs), belonging to the field of model lightweighting technology. The proposed method significantly reduces model size and computational load, greatly improves inference speed and control response performance, and enables the deployment of complex neural network controllers on resource-constrained airborne platforms. Simultaneously, the lightweight model maintains or approaches the control accuracy and stability of the original uncompressed model. This method has wide applicability and strong scalability, covering various scenarios from basic flight control to complex mission control, providing a feasible, efficient, and cost-effective solution for applying large models to airborne controllers of UAVs, and possesses high engineering practical value.

The application discloses a high-surface-quality 980MPa-grade hot-dip galvanizing DH steel and a preparation method thereof. The main chemical component mass content of the hot-dip galvanizing DH steel is as follows: C: 0.17-0.21%, Si: 0.4-0.7%, Mn: 1.8-2.2%, Nb: 0.01-0.02%, Ti: 0.01-0.02%, Cr: 0.4-0.5%, and Als: 0.14-0.9%. The method adopts low-carbon design and high-dew-point annealing process to produce the hot-dip galvanizing steel plate which meets the low-carbon environmental protection requirement and has high surface quality, so as to meet the urgent needs of the market. The high-dew-point annealing process is a new type of annealing technology, the oxygen partial pressure is increased by increasing the dew point, the Si and Mn element internal oxidation is realized, and thus the plating leakage defect is effectively improved, and the surface smoothness and flatness of the steel plate are improved.
