A TDD approach to introducing students to embedded programming
Learning embedded programming is a highly demanding exercise. The beginner is bombarded with complexity from the start: embedded production based around a myriad of C++ constructs with low-level elements integrated onto ever more complicated processor architectures. The picture is further compounded by tool support having unfamiliar roles and appearances from previous student experiences. This demanding situation often has the student bewildered; seeking for "a crutch" or the simplest way forward regardless of the overall consequences. To control this potentially chaotic picture, the instructor needs to introduce devices to combat this complexity. We argue that test driven development (TDD) should become the instructor's principal weapon in this fight. Reasons for this belief combined with our, and the students', experiences with this novel approach are discussed.

Cryptographic Information Recovery Using Key Recover
A note to readers: the authors consider that all techniques for key recovery may be viewed as having a position on a broad continuum. The only way to avoid misunderstanding is to identify particular techniques by listing their specific characteristics, rather than using multiply-defined terms. Different characteristics have advantages in different environments, so there is no 'best' key recovery technique. The paper notes some typical advantages and disadvantages of several techniques but should not be construed as an endorsement of any particular technique relative to another. Similarly, the authors recognize that terminology may vary from country to country. Cryptographic information recovery techniques provide for the recovery of plaintext from encrypted data. This (exceptional) need arises when the cryptographic keys involved are not available. For example, data files may have been encrypted using a key derived from a now forgotten or misplaced password. Overlapping and confusing terminology has been applied to the techniques of information recovery, including key escrow, key backup, key recovery, and trusted third party (ttp), all of which refer to methods for retrieving, recovering, or re-constructing keys. Even the underlying concept of 'trust' has broad meaning. Instead of attempting to 'define' these terms precisely, a continuum of functionality is defined. Several generic technologies, together with desirable characteristics of cryptographic information/key recovery techniques, are described.

Performance and Capacity Analysis of UWB Networks over 60GHz WPAN Channel
In this paper we evaluate the system performance and capacity of single carrier ultra-wideband (UWB) networks over 60GHz wireless personal area network (WPAN) channel. Symbol error rate is derived for both single user and multiple access scenario with a general system capacity and performance evaluation approach based on moment generation function. System outage probability and network throughput performance are also studied. Based on the current IEEE 802.15.3 WPAN standard work, different transmission scenarios have been explored and the performances with RAKE reception has been obtained. The channel model is also based on the recent work of IEEE 802.15 WPAN group. Numerical results are given to illustrate the system performance.

The CORC experience: survey of founding libraries. Part I
This survey, conducted in late 1999, found that CORC founding libraries shared a strong interest in controlling Internet resources and finding ways to catalog such resources quickly. Many cataloged in MARC. Although only a small number of them experimented with Dublin Core, many of them wanted to explore its potential for organizing Internet resources. Other metadata schemes were also used by some libraries. Overall, the founding libraries considered their CORC experience positive, but had several concerns. Their experience suggests that more work is needed to make fast, automated cataloging a reality. Since the findings of this study reflect experience with CORC at the developmental stage, the researchers proposed that CORC usage be monitored to identify trends in organizing Internet resources. A survey of CORC subscribers could be conducted to understand usage patterns and guide CORC’s development and improvement.
