This paper describes an experiment system framework that enables researchers to design and conduct task-based experiments for Interactive Information Retrieval (IIR). The primary focus is on multidimensional logging to obtain rich behavioral data from participants. We summarize initial experiences and highlight the benefits of multidimensional data logging within the system framework.

In this paper the linear fractional representation problem of systems with rational parametric uncertainty is revisited from a multidimensional systems perspective. It is shown how this problem can be solved using the elementary operations approach. The minimality of the linear fractional representations obtained using this approach and other methods will be discussed. An example is presented t...

BACKGROUND This cross validation study examined the reliability of the Multidimensional Pain Inventory (MPI) and the stability of the Multidimensional Pain Inventory Classification System of the empirically derived subgroup classification obtained by cluster analysis in chronic musculoskeletal pain. Reliability of the German Multidimensional Pain Inventory was only examined once in the past in ...

In emerging database applications that deal with large sets of multidimensional data, the performance of the query system significantly depends on the performance of its access methods and the underlying disk system. In recent years, hard disks are manufactured with multiple physical zones, where seek times and data transfer rates vary significantly across the zones. However, there is a marked ...

The purpose of this paper is to show how to combine some new results on internal stabilizability [11, 12, 14, 15] with a result on multidimensional linear systems, independently obtained by ByrnesSpong-Tarn and Kamen-Khargonekar-Tannenbaum in [2, 6], in order to prove a conjecture of Z. Lin [7, 8, 9]. In particular, we shall show that every internal stabilizable multidimensional linear system (...

During the last several years many publications concerning two and multidimensional digital filters have appeared (see [1], [2] and [3]). Having presented six counterexamples E. I. Jury [4] has shown that in extending the theorems developed for the one dimensional case to two and multidimensional systems many difficulties are encountered. It seems to be useful to investigate the relationship am...

Large-scale scientific experiments or simulation programs often generate large amounts of multidimensional data. Data volume may reach hundreds of terabytes (up to petabytes). In the present and the near future, the only practicable way for storing such large volumes of multidimensional data is tertiary storage systems. But commercial (multidimensional) database systems are optimized for perfor...

A multidimensional file is one whose data are characterized by several attributes, each specified in a given domain. A partial match query on a multidimensional file extracts all data whose attributes match the values of one or more attributes specified in the query. The disk allocation problem of a multidimensional file F on a database system with multiple disks accessible in parallel is the p...
