We have examined 365 versions of Linux. For every version, we counted the number of instances of common (global) coupling between each of the 17 kernel modules and all the other modules in that version of Linux. We found that the number of instances of common coupling grows exponentially with version number. This result is significant at the 99.99% level,(More)
1 Overview There are many ways of modeling the behavior of systems, and the use of state machines is one of the oldest and best known. State machines allow us to think about the " state " of a system at a particular point in time and characterize the behavior of the system based on that state. The use of this modeling technique is not limited to the(More)
The increase in maintenance of software and the increased amounts of reuse are having major positive impacts on the quality of software, but are also introducing some rather subtle negative impacts on the quality. Instead of talking about existing problems (faults), developers now discuss " potential problems, " that is, aspects of the program that do not(More)
BACKGROUND Dexmedetomidine is a highly selective alpha2-adrenoceptor agonist used for short-term sedation of mechanically ventilated patients. The analgesic profile of dexmedetomidine has not been fully characterized in humans. METHODS This study was designed to compare the analgesic responses of six healthy male volunteers during stepwise(More)
The design and implementation of a software system is the result of many interwoven sequences of decisions. Often, these decisions are made under less than ideal conditions of uncertainty and/or incomplete information. Furthermore, many of these decisions do not have clear " right/wrong " answers — they are value judgments dependent upon the current(More)
We present a case of tongue necrosis due to intraoperative pressure injury. A laryngeal mask airway with adhesive electrodes was inserted into the oropharynx, over an endotracheal tube, to facilitate glossopharyngeal nerve monitoring during craniotomy for a cerebellopontine angle tumor. The case, mechanisms of injury, and modifications to our current(More)
