We can use software to do most calculation but not use hardware. The most basic circuit doing calculation in the computer is binary adder. For example, we can use of addition to do subtracting, continuous adding to do multiplication, and continuous subtracting to do division.
在电脑的世界里,可以做任何数字系统且复杂的演算,但是大多数的演算都藉由软体来解决,而非用硬体直接进行各种演算,电脑的硬体或其他数位电路在做算术运算时,最基本的电路往往只有二进位加法器而已,至於减法可藉由补数的加法解决,乘法等於连续的加法,除法则是连续的减法,可见加法器在运算数位系统中的重要性。

In this thesis, we implement a computational procedure to categorize and classify 3-D objects from their contour under a simple environment. First, we use foreground detection, Canny edge detection and speedy GVF snake to obtain the object's contour. The contour is then used to establish the object's features. Two databases are built using methods which compute similarity by modified aspect-combination algorithm proposed by Cyr and Kimia and new proposed aspect-combination algorithm. By using these two databases, we recognize 3-D objects using four recognition methods and compare their performance. Finally, a conclusion is made that our newly proposed algorithm is better than the modified algorithm proposed by Cyr and Kimia.

Ant routing use Swarm-Intelligence for route discovery and also have multi-paths for backup and balance. However, the efficiency of ant routing can more and more go down in large-scale mobile ad hoc networks. For solving such condition, improving the efficiency of ant routing, this research proposes the algorithm that combines both the GRID and ant routing, called grid-based ant routing algorithm. GARA can improve efficiency of ant routing in large-scale mobile ad hoc networks.
对於解决路由上的一些问题,也因此有各种不同类别的路由方法被探讨,蚂蚁路由演算法利用群体智慧(swarm-intelligence)找寻路径,而且同时能够找到多条备援路径,但是,蚂蚁路由演算法会因为行动主机数目愈来愈多情况下,而导致路由演算法效率降低,因此本论文以GRID为概念,融入蚂蚁演算法中,让蚂蚁是采用网格对网格(grid-by-grid)方式传输,改善蚂蚁路由演算法在行动主机数目愈来愈多情况下的效率与效能。

A commutation error is then considered in addition to the conventional residual error to generate the innovative residual error. Such an error is applied into cost functions to derive finite impulse response and infinite impulse response filter-based adaptive algorithms for ANC applications, referred to as FxRLS/CE and FuRLS/FRE+CE algorithms, respectively. Convergence analyses based on Lyapunov stability criteria for time-varying discrete-time systems can be carried out for the FxLMS/CE, FxRLS/CE and FuRLS/ FRE+CE algorithms to ensure stability. Computer simulations and experiments demonstrate that the innovative residual error-based adaptive algorithms can free the restriction of the slow-adaptation assumption in the conventional ANC approaches.

First, the character clustering algorithm regards the character as our features and then it can cluster these sentences of our target words to the correct group without any other resources. The average precision is 66.1%. Second, in the concept clustering algorithm of the aggregate computing, we use HowNet as the knowledge base of our feature words and obtain the concepts of these words. We cluster the sentences which have the same or similar concepts of the feature words into the same group. And then we can complement some lacks of the character clustering algorithm. The average precision is 72.3%. Third, regarding the concept clustering algorithm of the sememe distance, we use the sememe distance to compute its concept similarity. It improved similarity measure of the concept clustering algorithm of the aggregate computing. It achieves 81% average precision and gets better cluster quality.
