The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control
and data transfer communication between ICs.
Some of the features of the I2C bus are:
• Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A
12V supply line (500mA max.) for powering the peripherals often may be present.
• Each device connected to the bus is software addressable by a unique address and simple
master/ slave relationships exist at all times masters can operate as master-transmitters or as
master-receivers.
• The I2C bus is a true multi-master bus including collision Detection and arbitration to prevent data
corruption if two or more masters simultaneously initiate data transfer systems.
• Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard
mode or up to 400 KBit/s in the fast mode.
The System Management BIOS Reference Specification addresses how motherboard and system vendors present
management information about their products in a standard format by extending the BIOS interface on Intel
architecture systems. The information is intended to allow generic instrumentation to deliver this data to
management applications that use CIM (the WBEM data model) or direct access and eliminates the need for error
prone operations like probing system hardware for presence Detection.

Ultra wideband (UWB) technology, well-known for its use in ground penetrating
radar, has also been of considerable interest in communications and radar applications
demanding low probability of intercept and Detection (LPI/D), multipath immunity, high
data throughput, precision ranging and localization.
It has been suggested1 that an appropriate figure of merit for a low probability of intercept and
Detection (LPI/D) waveform is the quantity “Range x Bandwidth / Joule”. That is, the further the
range, the wider the bandwidth and the less amount of energy used to achieve these values, the
more covert is the resultant communications system.

In this paper, we describe the development of a rapidly reconfigurable system in which the users’ tacit knowledge and requirements are
elicited via a process of Interactive Evolution, finding the image processing parameters to achieve the required goals without any need for
specialised knowledge of the machine vision system. We show that the resulting segmentation can be quickly and easily evolved from
scratch, and achieves Detection rates comparable to those of a hand-tuned system on a hot-rolled steel defect recognition problem.

在網絡安全中經常會遇到rootkit，NSA安全和入侵檢測術語字典( NSA Glossary of Terms Used in Security and Intrusion Detection)對rootkit的定義如下：A hacker security tool that captures passwords and message traffic to and from a computer. A collection of tools that allows a hacker to provide a backdoor into a system, collect information on other systems on the network,mask the fact that the system is compromised, and much more. Rootkit is a classic example of Trojan Horse software. Rootkit is available for a wide range of operating systems.
