Medical records have been used for a long time with different forms, aims, and usages. This heterogeneity is the result of different professions, ways of working, and needs. It is but prejudicial to querying and sharing data and documents. Moreover, we consider that the system must be as close as possible to a more classical, noncomputerized way of working, such as paper-based medical record, a...

This paper attempts to identify sources of resource use inefficiency for cotton production in Pakistan’s Punjab. The use of a non-parametric method, Data Envelopment Analysis (DEA), is developed to study the relative technical and allocative efficiencies of individual farms which use similar inputs, produce the same product and operate under comparable circumstances. In the ‘cotton–wheat’ syste...

The Inverse Frobenius-Perron problem (IFPP) concerns the creation of discrete chaotic mappings with arbitrary invariant densities. In this note, we present a new and elegant solution to the IFPP, based on positive matrix theory. Our method allows chaotic maps with arbitrary piecewise-constant invariant densities, and with arbitrary mixing properties, to be synthesized.

We introduce a novel approach for separating and segmenting individual facades from streetside images. Our algorithm incorporates prior knowledge about arbitrarily shaped repetitive regions which are detected using intensity profile descriptors and a voting–based matcher. In the experiments we compare our approach to extended state–of–the–art matching approaches using more than 600 challenging ...

Designing hypermedia systems might be a complex task as soon as the number of chunks of information to organize is large. In the task of designing hypermedia systems, interactive dynamic maps can provide designers with a better understanding of the semantics of the underlying set of documents, thus providing assistance in the design process. In this paper we present topic maps and techniques fo...

In this paper we propose an ontological framework for tools facilitating creative writing and story reading. It is based on an ontology implemented as a topic map and employs linguistic analysis methods for discovering conceptual entities in the text.

Given a cyclic group G and a generator g, the Diie-Hellman function (DH) maps two group elements (g a ; g b) to g ab. For many groups G this function is assumed to be hard to compute. We generalize this function to the P-Diie-Hellman function (P-DH) that maps two group elements (g a ; g b) to g P (a;b) for a (non-linear) polynomial P in a and b. In this paper we show that computing DH is comput...

Factorizations of the cyclic permutation (1 2 . . . N) into two permutations with respectively n and m cycles, or, equivalently, unicellular bicolored maps with N edges and n white and m black vertices, have been enumerated independantly by Jackson and Adrianov using evaluations of characters of the symmetric group. In this paper we present a bijection between unicellular partitioned bicolored ...
