In the case of a many-to-one foreign key-primary key join, it is almost certainly the case that ∣T1∣>∣T2∣, so Sort-Merge is faster even for B2=1. On the other hand, if, owing to an earlier selection process,
For example, just randomly modifying a ciphertext message could turn it into something that decrypts into valid-looking plaintext, in which case the tampering would be undetectable by the receiver. Nor does encryption alone provide authentication. It is not much use to say that a message came ...

Path planning is one of the most critical issues in many related fields including UAVs. Many researchers have addressed this problem according to different conditions and limitations, but modelling the 3-D space and routing with an evolutional algorithm
note 1: Small data velocity is aroughevaluation of algorithm's efficiency on small data. For more detailed analysis, please refer to next paragraph. note 2: some algorithms featurefaster than RAMspeed. In which case, they can only reach their full speed potential when input is already in CPU...
for each defect cluster (bounding box) throughout its lifetime. Figs.2a,b showcase examples of our ground truth annotation of a 1200-frame (2048 × 2048 pixels) TEM video, with each defect cluster labeled and tracked by a uniquely colored bounding box and tracking ID. Fig.2c shows ...
A real case study is presented in section “Case study”, where the energy consumption and PV production data are described in section “Energy consumption data” and “Energy production data”. Section “Results and discussion” presents and discusses the numerical results and discussion, and the...

These distances are described by (xi−xj)2+(yi−yj)2 for any pair of movable components i and j. In the case of fixed components, this expression is adapted to reflect this situation, (xi−xjf)2+(yi−yjf)2, where the subscript f denotes that the j component cannot be ...
In this example, we switch to PCR before the forward reduction has reached a 2-equation system, which enables us to skip the inefficient CR steps where the vector arithmetic unit is not fully utilized. Sign in to download full-size image Figure 11.4. The CR-PCR algorithm for an 8-...
