Let γ be a simple open smooth curve and α be an orientation-preserving diffeomorphism of γ onto itself which has only two fixed points. Criteria for one-sided invertibility of the functional operator
A=aIbW,
where a and b are continuous functions, I is the identity operator, W is the shift operator: (Wf)(t)=f[α(t)], in a reflexive rearrangement-invariant space of fundamental type X(γ) with nontrivial Boyd indices, are obtained.

Freitas, J. A. T., and C. Cismaşiu. "Developments with hybrid-{T}refftz stress and displacement elements." Computer Assisted Mechanics and Engineering Sciences. 8 (2001): 289-311. Abstract

The paper reports on the work on hybrid-{T}refftz finite elements developed by the Structural Analysis Research Group, ICIST, Technical University of Lisbon. A dynamic elastoplastic problem is used to describe the technique used to establish the alternative stress and displacement models of the hybrid-{T}refftz finite element formulations. They are derived using independent time, space and finite element bases, so that the resulting solving systems are symmetric, sparse, naturally $p$-adaptive and particularly well suited to parallel processing. The performance of the hybrid-{T}refftz stress and displacement models is illustrated with a number of representative static and dynamic applications of elastic and elastoplastic structural problems.

A new ornithopod dinosaur is described here under the name of Draconyx loureiroi n. gen., n. sp. on teeth, caudal vertebrae, forelimb, hindlimb, and foot material that were found in association in the Late Jurassic-Tithonian of Lourinhã, Portugal. Draconyx is a Camptosauridae related to Camptosaurus.

Lourenço, João M., and José C. Cunha. "Fiddle: A Flexible Distributed Debugging Architecture." Proceedings of the International Conference on Computational Science-Part II. {ICCS}'01. London, UK: Springer-Verlag, 2001. 821-830. Abstracticcs01.pdf

In the recent past, multiple techniques and tools have been proposed and contributed to improve the distributed debugging functionalities, in several distinct aspects, such as handling the non-determinism, allowing cyclic interactive debugging of parallel programs, and providing more user-friendly interfaces. However, most of these tools are tied to a specific programming language and provide rigid graphical user interfaces. So they cannot easily adapt to support distinct abstraction levels or user interfaces. They also don't provide adequate support for cooperation with other tools in a software engineering environment. In this paper we discuss several dimensions which may contribute to develop more flexible distributed debuggers. We describe Fiddle, a distributed debugging tool which aims at overcoming some of the above limitations.

Karlovich, Alexei Yu., and Lech Maligranda. "On the interpolation constant for Orlicz spaces." Proceedings of the American Mathematical Society. 129 (2001): 2727-2739. AbstractWebsite

In this paper we deal with the interpolation from Lebesgue spaces Lp and Lq, into an Orlicz space Lφ, where 1p<q and φ1(t)=t1/pρ(t1/q1/p) for some concave function ρ, with the special attention to the interpolation constant C. For a bounded linear operator T in Lp and Lq, we prove modular inequalities, which allow us to get the estimate, for both, the Orlicz norm and the Luxemburg norm,

where the interpolation constant C depends only on p and q. We give estimates for C, which imply C<4. Moreover, if either 1 < p < q \le 2 or 2 \le p < q < \infty, then C< 2. If q=\infty, then C\le 2^{1-1/p}, and, in particular, for the case p=1 this gives the classical Orlicz interpolation theorem with the constant C=1.

Camarinha-Matos, Luis M., Hamideh Afsarmanesh, Ersin Cem Kaletas, and Tiago Cardoso. "Service federation in virtual organizations." Digital Enterprise Challenges. Springer, Boston, MA, 2001. 305-324. Abstract

The practical implantation of the concept of dynamic virtual enterprise is still far from expectations due to a number of factors such as the lack of appropriate interoperable infrastructures and tools, lack of common ontology, and the socio-organizational difficulties. However, the creation of industry clusters supported by advanced information and communication tools can meanwhile provide a basis for the rapid creation of dynamic virtual enterprises in response to the market opportunities. A federated service management approach is introduced in this context and its application to the tourism industry is discussed. Finally, the support for the aggregation of simpler services into value-added services, implemented by distributed business processes within different organizations, is presented.

Monitoring systems have traditionally been developed with rigid objectives and functionalities, and tied to specific languages, libraries and run-time environments. There is a need for more flexible monitoring systems which can be easily adapted to distinct requirements. On-line monitoring has been considered as increasingly important for observation and control of a distributed application. In this paper we discuss monitoring interfaces and architectures which support more extensible monitoring and control services. We describe our work on the development of a distributed monitoring infrastructure, and illustrate how it eases the implementation of a complex distributed debugging architecture. We also discuss several issues concerning support for tool interoperability and illustrate how the cooperation among multiple concurrent tools can ease the task of distributed debugging.
