This note argues that, insofar as contemporary mathematics is concerned, there is overwhelming evidence that if mathematical objects are structures, then isomorphism should not be taken as their identity condition. This goes against a common version of structuralism in the philosophical literature. Four areas are presented in which identifying isomorphic structures or objects leads to contradictio

Iran is worried about the contagion effect of the Saudi military intervention in Yemen, that is, Tehran fears the experience, once successful, may be repeated elsewhere in the Middle East, particularly Syria, hence its stiff opposition and harsh reactions to it.

Microalgae is one of the prominent sources for biodiesel production. Cultivation of a specific microalgae strain (chlorella sp.) in wastewater using a pilot-scale open pond raceway was studied. Daily measurement of the raceway parameters such as pH, optical density and dissolved oxygen indicated that growth phase prolonged for 15 days and pH of the culture stayed on 9.4 for the most part of the pe

This paper describes a system that automatically converts narratives into 3D scenes. The texts, written in Swedish, describe road accidents. One of the key features of the program is that it animates the generated scene using temporal relations between the events. We believe that this system is the first text-to-scene converter that is not restricted to invented narratives. The system consists of

The implementation of industrial control applications typically introduces complexities like sampling jitter and control jitter, which have usually not been considered at the design stage. Consequently, the system behaves in a non-periodic manner and the real performance is degraded with regard to the expected response. This paper proposes a hybrid task model to reduce the impact of the scheduling

This paper discusses aspects of technological change and the path towards institutionalization of new innovations, with a focus on how users matter and are part of the co-construction of such change. An empirical example from the security industry is used to illustrate how two distinct phases in the analog-to-digital shift in video surveillance technology have had very different outcomes with resp

The present paper is a study of one impersonator and one of his voice imitations in order to find out how he changes his own voice and speech behaviour in order to get close to the target voice. Preliminary results from the auditory and the acoustic analysis, focusing on speech style and intonation pattern, will be presented.
