This paper is about algorithms that schedule tasks to be performed in a distributed failure-prone environment, when processors communicate by message-passing, and when tasks are independent and of unit length. The processors work under synchrony and may fail by crashing. Failure patterns are imposed by adversaries. The question how the power of adversaries affects the optimality of randomized a...

The marked shift in writing instruction from a focus on writing as a set of separate, sequential tasks to a focus on writing as a holistic gestalt prompted the empirical study reported in this paper. We sought to determine whether any prerequisite relationships existed between five analytical components of ESL composition, namely content, organization, vocabulary, language use, and mechanics. O...

The aim of this study was to quantify stability of nondominant handwriting kinematics and legibility in participants with functional loss of the previously dominant hand. Twelve adult volunteers provided two handwriting samples 6 weeks apart. Handwriting tasks (Compose a Sentence, Copy Alphabet, Copy Date, Copy Sentence, and Draw Circles) were performed in cursive writing on standard white, lin...

Software in general is thoroughly analyzed before it is released to its users. Business processes often are not – at least not as thoroughly as it could be – before they are released to their users, e.g., employees or software agents. This paper ascribes this practice to the lack of suitable instruments for business process analysts, who design the processes, their processes. We use the spreads...
