Software Quality model is a well-accepted way for assessing high-level quality characteristics (e.g., maintainability) by aggregation from low-level metrics. Aggregation method in a software quality model denotes how to aggregate low-level metrics to high-level quality characteristics. Most of the existing quality models adopt the weighted linear aggregation method. The main drawback of weighted linear...
The solubility of daidzin in different organic solvents and (ethyl alcohol+water) mixed solvents was measured by high performance liquid chromatography (HPLC) analysis method from T=(283.2 to 323.2)K at atmosphere pressure. The results show that at higher temperature more daidzin dissolves, and moreover, the solubility increases with the ethyl alcohol mole fraction increase in the (ethyl alcohol+water)...
In this paper, a improved algorithm based on convex hull vertices is proposed. After extracting feature points by Harris corner detector, for searching the same regions of reference images, correlation method is used to match these points firstly, which gains two initial pairing sets. Then convex hull vertices of the pairing sets are used to establish the transformation parameters that can match most...
Distributed detection mechanism of DDoS (distributed denial of service) attack is often achieved by the corporation between many detection nodes, its final detection result largely depends on the judgements of local nodes. While DDoS attack flows are distributed enough in many links, itpsilas hard to derive exact judgement for every node only by the information collecting from local, consequently...
