摘要： To detect color motion artifacts in a video frame, a motion-compensated color-distance value is compared against a threshold value. If the motion-compensated color-distance value is greater than or equal to the threshold value, color-motion artifacts are detected. The motion-compensated color-distance value is a sum of absolute values of the differences between corresponding pixel values of the video frame and a reference frame. To detect color motion artifacts in a video frame, in another embodiment, luminance and chrominance components of the intra-frame activity levels are compared against luminance and chrominance components of the inter-frame activity levels. If any of the components of the inter-frame activity levels is greater than the corresponding components of the intra-frame activity levels, color-motion artifacts are detected. To reduce color-motion artifacts, either a smaller quantization scale or intra-frame encoding is used to encode the data.

摘要： A portion of the number of bits initially allocated for encoding some of the frames of a group of pictures (GOP) is accumulated in a bit bank and is subsequently used to encode other frames that may require a larger number of bits to encode than those initially allocated for these frames. Furthermore, when a scene change P frame is detected in a first GOP, a second GOP is formed. The second GOP includes the scene change P frame as well as the remaining unencoded frames of the original GOP. The P frame of the first GOP is changed to an I frame in the second GOP. Furthermore, the frame to be displayed after the I frame of the second GOP is also changed to a duplicate of the I frame of the second GOP.
摘要翻译：最初分配用于编码一组图像（GOP）的一些帧的比特数的一部分被积累在比特组中，并且随后被用于编码可能需要比最初编码的比特数更多的比特的其他帧分配给这些帧。此外，当在第一GOP中检测到场景改变P帧时，形成第二GOP。第二GOP包括场景改变P帧以及原始GOP的剩余未编码帧。第一GOP中的P帧在第二GOP中改变为I帧。此外，在第二GOP的I帧之后要显示的帧也被改变为第二GOP的I帧的副本。

摘要： An exemplary method and system is disclosed that facilitate the integration of multiplexed single-cell impedance cytometry in a high throughput format, which can be deployed upstream from microfluidic sample preparation and/or downstream to microfluidic cell separation. In exemplary method and system may employ impedance-based quantification of cell electrophysiology on the same microfluidic chip (i.e., “on-chip”) to provide distinguishing phenotypic information on the sample, without the need for additional sample handling, preparation or dilution steps as would be needed for other flow cytometry techniques.

摘要： In one example, reclaiming obsolete regions includes a memory organized in aligned memory blocks and storing valid variables in valid regions and obsolete variables in the obsolete regions. A memory includes a buffer region to cache the memory. A controller can search the buffer region for the obsolete regions and pair with respective valid regions and determine if start addresses of the obsolete regions are memory aligned and if not aligned, to write a small portion content of a first valid region to the start address of the aligned memory block, and to write any remaining respective valid region beginning at the start address of the aligned memory block and in multiples of the aligned memory block. Upon completion of a writing, moved respective valid regions begin at the starting address of the obsolete regions and new obsolete regions begin at end addresses of the moved respective valid regions.

摘要： The present disclosure relates to a fire extinguishing composition containing saccharide and a saccharide derivative, comprising a saccharide derivative, a saccharide material and an auxiliary fire extinguishing agent, whose mass percentages are respectively: saccharide derivative 30%-60%, saccharide material 10%-40%, and auxiliary fire extinguishing agent 10%-30%. The fire extinguishing composition uses a pyrotechnic agent as a heat source and a power source, is heated and decomposed or reacts by using the heat of burning of the pyrotechnic agent, to generate a fire extinguishing material to be sprayed together with the fireworks agent, thereby achieving the fire extinguishing purpose. The fire extinguishing composition of the present disclosure uses a saccharide derivative and a saccharide material as primary ingredients, uses a pyrotechnic agent as a heat source and a power source, and is easily decomposed after being heated to generate non-toxic and harmless gas. The environment is not polluted after the ejection, the effective utilization rate of components is high, and the material obtained through decomposition can also extinguish fire, so as to generate a synergistic action on the pyrotechnic agent, thereby improving the fire extinguishing performance of the whole fire extinguishing composition.

摘要： The disclosure discloses a method for traffic limitation by a leaky bucket, including that: during traffic-limitation of a group of packets sharing a same leaky bucket and having separate weighted priorities, the overall leaky bucket is divided into multiple sub-buckets according to priority parameters of the packets including a number of the weighted priorities and ratios between the weighted priorities; after packet information is received, parameters relevant to traffic-limitation by a leaky bucket is acquired; a total number of tokens to be added to the overall leaky bucket is calculated; token-addition is performed on the sub-buckets according to a state of the overall leaky bucket after addition of the total number of tokens and the weighted priorities corresponding to the sub-buckets; a packet is forwarded, or discarded, or marked according to a length of the packet and a number of tokens in a sub-bucket corresponding to a weighted priority, wherein in performing token-addition on the sub-buckets, after token-addition is performed on all the sub-buckets, any overrunning token is allocated to another sub-bucket not overrun with tokens. The disclosure further discloses a device for traffic limitation by a leaky bucket. With the disclosure, it is possible to limit packet traffic flexibly according to weighted priorities and improve resource utilization.
