The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.

The code on this diskette has been organized by chapter. Each subdirectory containing listing has a readme.txt describing program usage and any relevent file formats. The readme will also describe how to compile the target programs under IBM OS/2 (TM) using the using C Set++ compiler (TM). All programs on this diskette have been compiled and tested in this environment. The majority of programs on this diskette should port to other environments with only minor adjustments. The exception to this are those programs which utilize presentation manager for graphical display of program data. In particular, the grid1 programs in \chapt4\backprop\ and \chapt3\ fall into this latter category.

This paper presents a visual based localization mechanism for a legged robot. Our proposal, fundamented on a probabilistic approach, uses a precompiled topological map where natural landmarks like doors or ceiling lights are recognized by the robot using its on-board camera. Experiments have been conducted using the AIBO Sony robotic dog showing that it is able to deal with noisy sensors like vision and to approximate world models representing indoor ofce environments. The two major contributions of this work are the use of this technique in legged robots, and the use of an active camera as the main sensor

This paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active Server Pages environment, but most of the techniques discussed have equivalents in other database environments. It should be viewed as a "follow up", or perhaps an appendix, to the previous paper, "Advanced SQL Injection". The paper covers in more detail some of the points described in its predecessor, providing examples to clarify areas where the previous paper was perhaps unclear. An effective method for privilege escalation is described that makes use of the openrowset function to scan a network. A novel method for extracting information in the absence of helpful error messages is described the use of time delays as a transmission channel. Finally, a number of miscellaneous observations and useful hints are provided, collated from responses to the original paper, and various conversations around the subject of SQL injection in a SQL Server environment.

It can be argued that the current free-software movement is the most important thing happening in computing today. We are in the midst of a major shift from all software being proprietary and closely held by individual companies to a large body of software that can be freely acquired and used by anyone for any purpose. Free software now includes not only programming language compilers and linkers, but numerous utilities, graphical user interface environments, and even entire operating systems.

Java technology is both a programming language and a platform. The Java programming language originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design and architecture decisions drew from a variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network-based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop

Abstract. The main aim of this research is to improve communication between student and teacher by using the developing mobile information technologies. Implementing such technologies in education may help to develop learning environments to share the knowledge among students and increase their motivation to possible highest level. Based on mobile equipments used in daily life an online student announcement system has been developed which aims to provide sharing of documents and communication ways between students and teachers.
