These early writers mostly recommended a minimum of 5 ft3 /min of outdoor air per person, but later writers increased that number. The present ASHRAE Standard 62 value is 20 ft3 /min for normal situations.

  • We propose a translation recommendation framework to integrate Statistical Machine Translation (SMT) output with Translation Memory (TM) systems. The framework recommends SMT outputs to a TM user when it predicts that SMT outputs are more suitable for post-editing than the hits provided by the TM. We describe an implementation of this framework using an SVM binary classifier.

  • The need for, and methods to conduct, media sanitization should be identified and developed before arriving at the system disposal phase in the system life cycle. At the start of system development, when the initial system security plan is developed (see NIST SP 800-18, Revision 1, Guide for Developing Security Plans for Information Technology Systems), media sanitization controls are developed, documented, and deployed. One of the key decisions that will affect the ability to conduct sanitization is choosing what media are going to be used with the system.

  • Kristiina JOKINEN University of Helsinki and Kari KANTO This paper describes the user expertise model in AthosMail, a mobile, speech-based e-mail system. The model encodes the system’s assumptions about the user expertise, and gives recommendations on how the system should respond depending on the assumed competence levels of the user. The recommendations are realized as three types of explicitness in the system responses. The system monitors the user’s competence with the help of parameters that describe e.g. the success of the user’s interaction with the system. ...
