The combinatorial core of the OVSF code assignment problem that arises in UMTS is to assign some nodes of a complete binary tree of height h (the code tree) to n simultaneous connections, such that no two assigned nodes (codes) are on the same root-to-leaf path. Each connection requires a code on a specified level. The code can change over time as long as it is still on the same level. We consider the one-step code assignment problem: Given an assignment, move the minimum number of codes to serve a new request. Minn and Siu proposed the so-called DCAalgorithm to solve the problem optimally. We show that DCA does not always return an optimal solution, and that the problem is NP-hard. We give an exact nO(h)-time algorithm, and a polynomial time greedy algorithm that achieves approximation ratio Θ(h). Finally, we consider the online code assignment problem for which we derive several results

A heap is a binary tree satisfying the following conditions: This tree is completely balanced. If the height of this binary tree is h, then leaves can be at level h or level h-1. All leaves at level h are as far to the left as possible. The data associated with all descendants of a node are smaller than the datum associated with this node.

All of Java s Input/Output (I/O) facilities are based on streams, which provide simple ways to read and write data of different types. Java provides many different kinds of streams, each with its own application. The universe of streams is divided into four large categories: input streams and output streams, for reading and writing binary data and readers and writers, for reading and writing textual (character) data. You re almost certainly familiar with the basic kinds of streams--but did you know that there s a CipherInputStream for reading encrypted data? And a ZipOutputStream for automatically compressing data? Do you know how to use buffered streams effectively to make your I/O operations more efficient? Java I/O, 2nd Edition has been updated for Java 5.0 APIs and tells you all you ever need to know about streams--and probably more.

Introduction Sometimes you may collide with the following problem: a third-party binary component or control embedded into your application displays windows (usually message boxes) that hang your code until they are closed. If you do not have the source code of this binary and one does not have a good API to change one’s bad behaviour programmatically, it can be a real headache using the one. A famous example of such a binary is the WebBrowser control in .NET.

Heapsort 1.A heap is a binary tree satisfying the followingconditions: -This tree is completely balanced. -If the height of this binary tree is h, then leaves can be at level h or level h-1. -All leaves at level h are as far to the left as possible. -The data associated with all descendants of a node are smaller than the datum associated with this node. Implementation 1.using a linear array not a binary tree. -The sons of A(h) are A(2h) and A(2h+1). 2.time complexity: O(n log n)
