Sector is a system infrastructure software that provides functionality for distributed data storage, access, and analysis/processing. It automatically manages large volumetric data across servers or clusters, even those over distributed wide area high speed networks. Sector provides simple tools and APIs to access and/or process the data. Data and server locations are transparent to users, as the whole Sector network is a single networked super computer to the users.

sfrmat is a Matlab function that provides a spatial frequency response* (SFR) from a digital image file containing a slanted-edge feature. The specific edge-gradient algorithm follows the intent of the standard ISO 12233, developed by Technical Committee ISI/TC 42, for resolution measurements for electronic still pictorial cameras.

IP地址將不同的物理地址統一起來,從而將物理地址隱藏起來,上層軟件使用IP地址標識結點。但是,兩臺計算機只有在知道彼此的物理地址時才能進行通信。 IP數據包常通過Ethernet發送。Ethernet設備并不識別32位IP地址,它們是以48位MAC地址傳輸Ethernet數據包的。因此,IP驅動器必須把IP目的地址轉換成Ethernet網絡目的地址。這兩種地址之間存在著某種靜態的或動態的映射,通常需要查看一張表來進行這種映射。地址解析協議(Address Resolution Protocol,ARP)就是用來確定這些映象的協議。 ARP工作時,送出一個含有所希望的IP地址的Ethernet廣播數據包。目的地主機(或另一個代表該主機的系統)以一個含有IP和Ethernet地址對的數據包作為應答。發送者將這個地址對高速緩存起來,以節約不必要的ARP通信

After an introduction to the history of mobile communications, this guide considers the basics of mobile radio, the design of cellular and private radio systems, and issues of interworking with the fixed network. It then looks at the role of the mobile radio operator, the design and operation of mobile radio networks, the needs of large user groups, and relevant regulatory and government decisions. A final section focuses on career development through resolution of conflicts, understanding managerial issues, and professional vehicles.

頂點倒塌(Vertex Collapse)算法中,一開始圖中的N個頂點看作N個孤立的超頂點(Super Vertex),算法運行中,有邊連通的超頂點相繼合并,直到形成最后的整個連通分量。每個頂點屬于且僅屬于一個超頂點,超頂點中標號最小者稱為該超頂點的根。

實驗8 繼承與多態 8.1 實驗目的 (1) 理解類的繼承,掌握變量隱藏、方法覆蓋的概念。 (2)理解引用類型的變量的賦值轉換原則。 (3)理解多態概念,掌握方法的匹配調用原則; (4)理解抽象類與接口的使用; (5)理解this和super的含義及使用。 (6)理解訪問控制符的使用 8.2 知識要點 8.2.1 繼承的概念 通過類的繼承,祖先類的所有成員均將成為子類擁有的“財富”。但是能否通過子類對象直接訪問這些成員則取決于訪問權限設置。Object類是所有類的祖先。 8.2.2 構造方法與繼承關系 構造方法不存在繼承關系,子類中是如何給父類繼承的屬性賦初值呢? 子類通過調用父類的構造方法給父類的屬性賦值,在子類的構造方法的第1行可以通過super去調用父類的構造方法,如果沒有super調用,則默認調用父類的無參構造方法。所以,在父類中編寫構造方法通常均要提供無參構造方法。 8.2.3 對象引用變量賦值原則 可以將子類的對象引用賦值給父類引用變量,由于父類能操作訪問屬性和方法的子類已全部繼承。但將父類引用變量的值賦給子類引用變量就受到限制,必須進行強制轉換,編譯總是認可強制轉換,但運行程序時如果不能正確轉換就會報錯。
