Wireless communications support a new form of data delivery in which servers broadcast data to a number of clients that listen to the broadcast channel and retrieve data of interest as they arrive on the channel. In this paper, we address the problem of ensuring the consistency and currency of read-only transactions when the values of broadcast data change. We identify a set of criteria that me...

We present PermiSTM, a single-version STM that satisfies a practical notion of permissiveness, usually associated with keeping many versions: it never aborts read-only transactions, and it aborts other transactions only due to a conflicting transaction (which writes to a common item), thereby avoiding spurious aborts. It avoids unnecessary contention on the memory, being strictly disjoint-

The WWW makes learning materials widely accessible and provides an environment where people can learn across time and space. However, the simple read-only information structure on the Web provides little or very limited guidance to learners, especially when they want to learn how to do something through interaction with computers and other people. We suggest overcoming the problem by introducin...

VoID (Vocabulary of Interlinked Datasets) has been proposed by W3C as the vocabulary for expressing metadata about RDF datasets. Despite its important contributions, VoID cannot express metadata that concern the connectivity of semantic warehouses. We use the term semantic warehouse to refer to a read-only set of RDF triples fetched (and transformed) from different sources that aims at serving ...

I was very much interested in the article by Rom and Ansbacher entitled "An Adlerian Case or a Character by Sartre?" (4) not only because of its intrinsic value but also because I had myself analyzed the hero of Sartre's story "Erostratus" (5, pp. 41-58) and others of this author's characters from the angle of Adler's Individual Psychology some I 5 years ago (6, 7). Before quoting from this ana...

Process mining enables multiple types of process analysis based on event data. In many scenarios, there are interesting subsets of cases that have deviations or that are delayed. Identifying such subsets and comparing process mining results is a key step in any process mining project. We aim to find the statistically most interesting patterns of a subset of cases. These subsets can be created b...
