You have an application that reads in configuration data at start-up. Your program consists of multiple threads with similar functionality. Some of the configuration data applies to all threads; the other part of the data applies to individual threads only. The configuration data should be read-only after it has been provided at start-up. This paper introduces the pattern Configuration Provider...

Social psychological research often relies on measures of group identification in assessing levels o f group consciousness. However, for women, the relationship between gender identification and group consciousness may not be a straightforward one. Questionnaire data were used to examine the relationships between measures of group identity and group evaluations with other attitudinal, phenomeno...

We present a method for eecient conversion of diierential (chosen-plaintext) attacks into the more practical known-plaintext and ciphertext-only attacks. Our observation may save up to a factor of 2 20 in data over the known methods, assuming that plaintext is ASCII encoded English (or some other types of highly redundant data). We demonstrate the eeectiveness of our method by practical attacks...

We examine the power of quantum Turing machines (QTM’s) which compute string-valued functions of their inputs using small workspace. A (probabilistic or quantum) Turing machine has three tapes: A read-only input tape, a read/write work tape, and a “1.5-way" write-only output tape. Consider a partial function f : Σ 1 → Σ 2 , where Σ1 and Σ2 are the input and output tape alphabets, respectively. ...
