On the other hand, as proved in this paper, the problem is NP -complete even if we restrict it to graphs which are bipartite, planar and of maximum degree at most 3 and to functions f , g where the permitted values are 1 and 2, only. We also show that the analogous problem, ...

indeed, subject-specific, we estimated weights using three of every subject’s four resting state scans, and used those weights to predict the activity of the held-out scan (as
Use the mutual coupling impedance equation to analyze the deterioration degree of amplitude and phase for phase weighting arrays antennas. 采用分段正弦基函数Galerk in法计算了阵列天线的阻抗矩阵,利用互耦阻抗方程分析了相位加权阵列的幅相恶化程度,且用矩量法分析了互耦对两种相对加权阵列天线性能的影响。
Once the noisy pixels are detected, a weighted mean of noise free pixels, based on the sum of degree of compatibility [84] between the center pixel and its neighbors in the selected window, is calculated and later used to replace the corrupted pixels. The authors of SAWMF also use the ...

We denote corresponding average degree of each user and each item, respectively, as 𝑑𝑢̂ and 𝑑𝑖̂ . It is noted that 𝑑𝑢 , 𝑑𝑖 , 𝑑𝑢̂ and 𝑑𝑖̂ are generally smaller than m or n. Thus, the overall complexity of the recommendation stage is low. ...
VWAP's incorporation of volume is valuable to traders for what it can indicate about the degree of trading activity during short periods of time—whether the competition is taking or exiting positions. VWAP vs. Simple Moving Average On a chart, VWAP and asimple moving average (SMA)may look ...

In this paper, the impact factors of in-degree and out-degree are introduced into community detection, and the directed weighted degree is used to measure the importance of the node. Based on the core nodes, a community detecting algorithm for directed and weighted networks is proposed. Then ...
