Description: This project is to show the tree I dreamed when I first met the ternary tree concept. When I came upon the ternary tree, I get awed! It s amazing that an idea so simplistic could be so strong and fast. But it had flaws... the first one is the memory consumption. The hash table implementation consumes far less memory than the ternary tree! The second flaw is the ternary tree can be fragmented and be extremely unbalanced (as the algorithm doesn t do any balancing step) so the tree also needs a way for balancing the nodes. I tried to reduce the memory consumption by grouping three nodes into one new \"int\" node. -This project is to show the tree I dreamed wh en I first met the ternary tree concept.

Description: 红黑树是一种自平衡二叉查找树，是在计算机科学中用到的一种数据结构，典型的用途是实现关联数组。-AVL trees are actually easier to implement than RB trees because there are fewer cases. And AVL trees require O(1) rotations on an insertion, whereas red-black trees require O(lg n).
In practice, the speed of AVL trees versus red-black trees will depend on the data that you re inserting. If your data is well distributed, so that an unbalanced binary tree would generally be acceptable (i.e. roughly in random order), but you want to handle bad cases anyway, then red-black trees will be faster because they do less unnecessary rebalancing of already acceptable data.On the other hand, if a pathological insertion order (e.g. increasing order of key) is common, then AVL trees will be faster, because the stricter balancing rule will reduce the tree s height.
Splay trees might be even faster than either RB or AVL trees,depending on your data access distribution. And if you can use a hash instead of a tree, then that ll be fastest of all.

Description: a transmission line fault location model which is based on an Elman recurrent network
(ERN) has been presented for balanced and unbalanced short circuit faults. All fault situations with
different inception times are implemented on a 380-kV prototype power system. Wavelet transform
(WT) is used for selecting distinctive features about the faulty signals. The system has the advantages of
utilizing single-end measurements, using both voltage and current signals. ERN is able to determine the
fault location occurred on transmission line rapidly and correctly as an important alternative to standard
feedforward back propagation networks (FFNs) and radial basis functions (RBFs) neural networks.

Description: This paper, focus on the study and design of a shunt active power (APF) filter for the compensation of harmonic currents and reactive power in polluted environment and under unbalanced network voltage. In APF design and control, p-q theory was often served as the basis for the calculation of compensation current. In this theory, the mains voltage was assumed to be an ideal source in the calculation process. However, in most of time and most of industry power systems, mains voltage may be unbalanced and/or distorted. For these reasons, we used a new technique with instantaneous power theory (p-q theory) based on Phase Locked Loop (PLL) in order to control APF under unbalanced mains voltage. A pulse width modulation (PWM) technique is used to generate the switching signals to the shunt APF.-This paper, focus on the study and design of a shunt active power (APF) filter for the compensation of harmonic currents and reactive power in polluted environment and under unbalanced network voltage.
