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

In the bank all the activities are being done manually .As the bank widens its services & it finds difficult to manage its operations manually and hence this leads to the automation of some of its operations. Banking Information system is a windows based applications. This project mainly deals with managing there types of account such as Saving Account, Current Account and Recurring Deposits . In this project bank is seeking to manage these account through computer based system. Tasks involved in this project are opening the user accounts , recording the account holders transactions , modify, the user records and generating the reports . This project is having three module: ] 1. Bank Master Module 2. Transaction Module 3. Reports module

Although some FX1-based devices may use the FX1鈥檚 CPU to process USB data directly (Port I/O Mode), most applica- tions use the FX1 simply as a conduit between the USB and external data-processing logic (e.g., an ASIC or DSP, or the IDE controller on a hard disk drive).

The driver supports both the 16F and 18F families. The trick is that the driver carefully emulates the hardware UART found in the PIC18F452 processor. This information has unfortunately misled some into thinking it does not work with the 16F family. During devlopment the driver was tested on a real PIC16F84A (as opposed to software emulation). To make sure nothing has been broken, I have just recompiled the code using SourceBoost 6.0 and it compiled without error.

Fortran has always been the principal language used in the fields of scientific, numerical, and engineering programming, and a series of revisions to the standard defining successive versions of the language has progressively enhanced its power and kept it competitive with several generations of rivals. Beginning in 1978, the technical committee responsible for the development of Fortran standards, X3J3 (now called J3), laboured to produce a new, much- needed modern version of the language, Fortran 90. Its purpose is to "promote portability, reliability, maintainability, and efficient execution... on a variety of computing systems". The standard was published in 1991, and work began in 1993 on a minor revision, known informally as Fortran 95. Now this revised

In the last decade the processing of polygonal meshes has emerged as an active and very productive research area. This can basically be attributed to two developments: Modern geometry acquisition devices, like laser scanners and MRT, easily produce raw polygonal meshes of ever growing complexity Downstream applications like analysis tools (medical imaging), computer aided manufacturing, or numerical simulations all require high quality polygonal meshes as input. The need to bridge the gap between raw triangle soup data and high-quality polygon meshes has driven the research on ecient data structures and algorithms that directly operate on polygonal meshes rather than on a (most often not feasible) intermediate CAD representation.

This application report discusses the design of non-invasive optical plethysmography also called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). The pulsoximeter consists of a peripheral probe combined with the MCU displaying the oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both heart-rate detection and pulsoximetering in this application. The probe is placed on a peripheral point of the body such as a finger tip, ear lobe or the nose. The probe includes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) and the other in the infrared spectrum (940nm). The percentage of oxygen in the body is worked by measuring the intensity from each frequency of light after it transmits through the body and then calculating the ratio between these two intensities.

As I write this foreword, I am collaborating with four leading user interface (UI) component vendors on a presentation for the 2004 JavaOneSM conference. In our presentation, the vendors will show how they leverage JavaServerTM Faces technology in their products. While developing the presentation, I am learning some things about the work we’ve been doing on JavaServer Faces for the past three years. The vendors have their own set of concerns unique to adapting their product for JavaServer Faces, but they all voice one opinion loud and clear: they are very relieved to finally have a standard for web-based user interfaces.

This book covers the fundamental concepts of data mining, to demonstrate the potential of gathering large sets of data, and analyzing these data sets to gain useful business understanding. The book is organized in three parts. Part I introduces concepts. Part II describes and demonstrates basic data mining algorithms. It also contains chapters on a number of different techniques often used in data mining. Part III focusses on business applications of data mining. Methods are presented with simple examples, applications are reviewed, and relativ advantages are evaluated.
