Why do People Program? Each person can have his own reason for programming but I can tell you that programming is one of the best ways to gain a deep understanding of computers and computer technology. Learning to program makes you understand why computers and computer programs work the way they do. It also puts some sense into you about how hard it is to create software. 1.2. What is C++ & OOP? C++ is an extended version C. C was developed at Bell Labs. in 1978.

It’s your first day in the lab.Undoubtedly you are experiencing a range of emotions: excitement, curiosity, anxiety. You will be working in this lab and with a group of people, as well as with your supervisor, for several years to come. This is the first day of a long commitment and, for some, a hard road ahead. Which is why it’s important to get off on the right foot.

Computes all eigenvalues and eigenvectors of a real symmetric matrix a, ! which is of size n by n, stored in a physical np by np array. ! On output, elements of a above the diagonal are destroyed. ! d returns the eigenvalues of a in its first n elements. ! v is a matrix with the same logical and physical dimensions as a, ! whose columns contain, on output, the normalized eigenvectors of a. ! nrot returns the number of Jacobi rotations that were required. ! Please notice that the eigenvalues are not ordered on output. ! If the sorting is desired, the addintioal routine "eigsrt" ! can be invoked to reorder the output of jacobi.

利用simulink搭建異步電機(jī)模型； 掌握異步電機(jī)各參數(shù)對(duì)各輸出的影響。 1.搭建異步電機(jī)模型，電機(jī)參數(shù)：定子電阻Rs=1歐姆，轉(zhuǎn)子電阻Rr=1歐姆，定子漏感系數(shù)=1mH，轉(zhuǎn)子漏感系數(shù)=1mH，互感系數(shù)=20mH，轉(zhuǎn)動(dòng)慣量Jm=0.25kgm^2，極對(duì)數(shù)Np=4。 2.用幅值為380V，頻率為50Hz，相位互差120度的三相勵(lì)磁交流電壓供電。先空載啟動(dòng)觀察各輸出變化，然后在空載穩(wěn)定后突加200Nm負(fù)載觀察各輸出變化。 3.分別改變Rs，Rr，Jm值，觀察輸出數(shù)據(jù)變化。

遺傳算法已經(jīng)成為組合優(yōu)化問(wèn)題的近似最優(yōu)解的一把鑰匙。它是一種模擬生物進(jìn)化過(guò)程的計(jì)算模型，作為一種新的全局優(yōu)化搜索算法，它以其簡(jiǎn)單、魯棒性強(qiáng)、適應(yīng)并行處理以及應(yīng)用范圍廣等特點(diǎn)，奠定了作為21世紀(jì)關(guān)鍵智能計(jì)算的地位。 背包問(wèn)題是一個(gè)典型的組合優(yōu)化問(wèn)題，在計(jì)算理論中屬于NP-完全問(wèn)題， 其計(jì)算復(fù)雜度為，傳統(tǒng)上采用動(dòng)態(tài)規(guī)劃來(lái)求解。設(shè)w是經(jīng)營(yíng)活動(dòng) i 所需要的資源消耗，M是所能提供的資源總量，p是人們經(jīng)營(yíng)活動(dòng)i得到的利潤(rùn)或收益，則背包問(wèn)題就是在資源有限的條件下， 追求總的最大收益的資源有效分配問(wèn)題。

《笨辦法學(xué) Python》(Learn Python The Hard Way，簡(jiǎn)稱(chēng) LPTHW)是 Zed Shaw 編寫(xiě)的一本 Python 入門(mén)書(shū)籍。適合對(duì)計(jì)算機(jī)了解不多，沒(méi)有學(xué)過(guò)編程，但對(duì)編程感興趣的朋友學(xué)習(xí)使用。這本書(shū)以 習(xí)題的方式引導(dǎo)讀者一步一步學(xué)習(xí)編程，從簡(jiǎn)單的打印一直講到完整項(xiàng)目的實(shí)現(xiàn)。也許讀完這本書(shū)并不 意味著你已經(jīng)學(xué)會(huì)了編程，但至少你會(huì)對(duì)編程語(yǔ)言以及編程這個(gè)行業(yè)有一個(gè)初步的了解。

The concept of “smart city” is often used implying that the reader has a clear and common notion of what it means. However, in the current literature it is very hard to find a precise definition. What is even more interesting, it is not so easy to find a precise definition of what a city is.
