Abstract: This paper presents theoretical analysis of microstructure changes in the material during standard rolling and normalizing rolling of the 35x20 mm flat bars. The analysis was carried out by means of computer software Forge 2007® that is based on finite element method. Two cases of accelerated cooling during rolling process were considered. Numerical results of 35x20 mm flat bars rolling process allowed determining the average recrystallized austenite diameter as well as basis energy and force parameters. Proposed modification of the 35x20 mm flat bar rolling technology with accelerated cooling results in the reduction of average austenite diameter, which could improve the strength of the final product.

Abstract: This paper proposes a new concept for sensor network data processing inspired by the theory of image processing. We draw the analogy between the nature of sensor networks and digital images in data formation, space and time. As sensor technology evolves and advances in the era of pervasive computing and networking, the need for innovative ways to efficiently and effectively digest the overwhelming data collected by these devices is a serious challenge. As we explore the literature in the area of sensor networks, we find previous work has been focused on issues like: deployment, communication protocols, energy efficiency, clustering schemes, security, etc. On the other hand, we see insignificant effort in trying to find innovative ways that exploit already proven theories to make sense of the overall situation perceived by a sensor network. Our effort in this work is to investigate the theory of image processing and propose a methodology on how this theory can be utilized to serve sensor network technology. We provide simulated scenarios in the experimental work section to support the validity of the proposed concept.
