Frequently, it is convenient to describe a program in terms of the normal situations in which it will be used, even if such a description does not describe the its complete behavior in all circumstances. This paper surveys the issues surrounding the description of program behavior in exceptional

It is difficult to write programs that behave correctly in the presence of run-time errors. Proper behavior in the face of exceptional situations is important to the reliability of long-running programs. Existing programming language features often provide poor support for executing clean-up code

Abstract. Treating exceptional situations in logic-based agents is often an implicit mechanism due to the capabililities of their reasoning engines. We argue in this paper that explicit mechanisms can provide interesting knowledge to the agent and its owner about its execution, thus allowing more

Software flaws in native methods may defeat Java’s guarantees of safety and security. One common kind of flaws in native methods results from the discrepancy on how exceptions are handled in Java and in native methods. Unlike exceptions in Java, exceptions raised in the native code through the Java

proposed. However, since the models treat work process as a target of transaction, it is difficult to adapt to exceptions or dynamic reconfiguration of processes. In this paper, we argue about examples of handling exceptions in an environment involving workflow processes and database transactions

ubiquitous museums, we had proposed Visitor Preference based Museum Viewing Search Algorithm that provides the best path for visitors to reflect their preferences. However, since the Visitor Preference based Museum Viewing Search Algorithm did not consider abnormal situations that occur while visitors look

Postpneumonectomy syndrome is a rare complication occurring after pneumonectomy. It is defined as extrinsic com-pression of a bronchus associated with a significant shift of the mediastinum. A man aged 45 years with history of C7 tetraparesis, presented with a postpneumonectomy-like syndrome 2 months after a right lower lobectomy. We per-formed a right pneumonectomy combined with implantation of 2 intrathoracic inflatable mammary implants. The patient remained asymptomatic after 6 months of follow-up. We believe this is the first reported case of a postpneumonectomy-like syndrome occurring after lobectomy.

in different situations. The results reveal that a new feature selection metric we call ‘Bi-Normal Separation ’ (BNS), outperformed the others by a substantial margin in most situations. This margin widened in tasks with high class skew, which is rampant in text classification problems and is particularly

such methodologies are developed, it will remain impractical to use activation theory in predicting or changing employee reactions to their jobs except in a very gross fashion; e.g., in situations where it is clear that most employees are enormously over-or understimulated by their jobs. A second problem has to do

of the word "most" is made rigorous by isoperimetric-type inequalities that bound the measure of the exceptional sets. The meaning of the work "close" is defined in three main ways, each of them giving rise to related, but different inequalities. The inequalities are all proved through a
