Adventures in XSC: our six-week countdown to extended service coverage
Authors: Jeffrey Lane, Annette Cutino, Marilyn McMillan
Venue: Proceedings of the 30th annual ACM SIGUCCS conference on User services (2002)

In Summer 2001, Information Technology Services (ITS) - New York University's central IT organization serving some 65,000 students, faculty, and staff - was charged with taking major steps toward meeting our clients' growing requirements for round-the-clock IT services and support. From this, our Extended Services Coverage project (XSC) was begun.ITS had been formed two years earlier when three distinct IT organizations were combined under the leadership of the University's first Chief Information Technology Officer (CITO). XSC's Phase I allotted ITS a mere six weeks' time to gear up and extend integrated, formalized business-hours-type support to all our services during evenings, nights, and weekends. Helpdesk hours alone would be increased by more than 73%; onsite technical system support during "off-hours" would also be significantly increased - for University administrative systems, NYU-NET, e-mail, and instructional systems. We would need to be ramped up by the time students and faculty returned at the end of August.All this raised significant challenges for ITS' 200-member staff. XSC would require changing how we worked together. We would need to devise incident management workflows and operating procedures that cut across previously distinct service groups; formalize notification procedures and mechanisms for our staff, service partners, and clients; develop standard protocols for prioritizing, routing, escalating and resolving problem reports; quickly recruit new staff and train all staff in new procedures; and measure, track and improve our practices systematically.This paper will outline ITS' early experiences with XSC - challenges, implementation issues, and future plans - particularly from the perspectives of the managers of the two helpdesks from which XSC processes are initiated. We will also note how we leveraged on initiatives already underway with respect to our helpdesk procedures and Remedy incident management system, and how, as an unanticipated benefit of XSC, we were better prepared to support the NYU community in dealing with the September 11 WTC tragedy and its aftermath.

Connections in acyclic hypergraphs: extended abstract
Authors: David Maier, Jeffrey D. Ullman
Venue: Proceedings of the 1st ACM SIGACT-SIGMOD symposium on Principles of database systems (1982)

We demonstrate a sense in which the equivalence between blocks (subgraphs without articulation points) and biconnected components (subgraphs in which there are two edge-disjoint paths between any pair of nodes) that holds in ordinary graph theory can be generalized to hypergraphs. The result has an interpretation for relational databases that the universal relations described by acyclic join dependencies are exactly those for which the connections among attributes are defined uniquely. We also exhibit a relationship between the process of Graham reduction [6] of hypergraphs and the process of tableau reduction [1] that holds only for acyclic hypergraphs.

Patterns for web applications
Authors: Diego Bonura, Rosario Culmone, Emanuela Merelli
Venue: Proceedings of the 14th international conference on Software engineering and knowledge engineering (2002)

This paper presents the preliminary results achieved in introducing a new formalism into the Web business logic layer. New useful and consistent patterns have been defined to support the modelling phase of web applications. The innovation in the use of patterns is extremely important when concepts like solidity, stability and reuse are crucial for the application design. The proposed patterns are graphically modelled using the Unified Modelling Language and formalized using the Object Constraints Language introduced by IBM. The new patterns are suitable for use in a CASE tool, to help developers build web solutions and eliminate inconsistences often present in natural languages.

Efficient evaluation of multiple queries on streaming XML data
Authors: Mong Li Lee, Boon Chin Chua, Wynne Hsu, Kian-Lee Tan
Venue: Proceedings of the eleventh international conference on Information and knowledge management (2002)

Traditionally, XML documents are processed at where they are stored. This allows the query processor to exploit pre-computed data structures (e.g., index) to retrieve the desired data efficiently. However, this mode of processing is not suitable for many applications where the documents are frequently updated. In such situations, efficient evaluation of multiple queries over streaming XML documents becomes important. This paper introduces a new operator, mqX-scan, which efficiently evaluates multiple queries with a single pass on streaming XML data. To facilitate matching, mqX-scan utilizes templates containing paths that have been traversed to match regular path expression patterns in a pool of queries. Results of the experiments demonstrate the efficiency and scalability of the mqX-scan operator.

Using GSM to enhance e-commerce security
Authors: Vorapranee Khu-smith, Chris J. Mitchell
Venue: Proceedings of the 2nd international workshop on Mobile commerce (2002)

Today, an e-commerce transaction is typically protected using SSL/TLS@. However, there remain some risks in such use of SSL/TLS@. These include that of information being stored in clear at the end point of the communication link and lack of user authentication. Although SSL/TLS does offer the latter, the security service is optional and usually omitted. This is because of the fact that users typically do not have the necessary asymmetric key pair. Since SSL/TLS protects data only while it is being transmitted, the merchant has access to sensitive information such as the debit/credit card number. The storage of unencrypted debit/credit card information at the merchant server therefore represents a risk that is not currently addressed by the use of SSL/TLS to secure electronic payment transactions.In this paper, we propose a payment protocol in which the risk of having debit/credit card details stored at a merchant server is eliminated. User authentication is also provided. This is achieved by utilising the GSM data confidentiality service to encrypt sensitive information. The GSM security service is also used to provide user identity authentication. The additional security is realised in such a way that no management overhead is imposed on the user.

On the Dimension of the Set of Rim Perturbations for Optimal Partition Invariance
Authors: Harvey J. Greenberg, Allen G. Holder, Kees Roos, Tamás Terlaky
Venue: SIAM Journal on Optimization (1998)

Two new dimension results are presented. For linear programs, it is shown that the sum of the dimension of the optimal set and the dimension of the set of objective perturbations for which the optimal partition is invariant equals the number of variables. A decoupling principle shows that the primal and dual results are additive. The main result is then extended to convex quadratic programs, but the dimension relationships are no longer dependent only on problem size. Furthermore, although the decoupling principle does not extend completely, the dimensions are additive, as in the linear case.
