Data produced by three dimensional MHD calculations are often difficult to visualize. Here we present a technique to view field lines of vector fields and one to display multiple isosurfaces of scalar fields. These methods do not rely on expensive commercial software and are general enough to be applied to other research sectors where visualization of 3D fields is important. Printed copies of t...

Hot forging of an Fe-Ni-Co alloy used for aeronautical purposes has been modeled using the commercial software ABAQUSTM/Explicit in order to obtain all the mechanical and thermal information to proceed with piercing and ring rolling. The material used is a 909 Incoloy type super alloy and it is used for the energy generation industry. Information of the constitutive behaviour of the alloy was i...

MobiHealth and HealthService24 are two major EU projects targeting the development and validation, with extensive medical trials, of innovative systems and services for mobile health care. Biosignals are measured by sensor devices connected to a wireless Body Area Network. These signals are transmitted reliably and securely over public wireless networks (e.g. GPRS, UMTS) to a remote healthcare ...

Software free trial is a common practice that has both positive and negative effects. On the one hand, it helps firms to exploit the positive network externalities by building up the total user base; on the other hand, it cannibalizes partial demand for the commercial software. The objective of my dissertation is to determine the conditions under which the firms should introduce the free trial ...

This study investigated the effect of Rumex Sc (commercial product which includes of Saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. Animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). Additionally, Rumex Sc was included in the experimental d...

Open source software (OSS) has become an increasingly threatening competitor to traditional proprietary software. In this paper, we study the competition between proprietary and OSS by considering consumer’s taste difference using a Hotelling model. In particular, we seek to answer how commercial software vendors should optimally set the price and design its product. Our analysis suggests that ...

Background: Doogh is a popular dairy beverage in Iran which its main ingredient is yogurt. The aim of this study was evaluation of bacterial and fungal contamination of this product marketed in Lorestan province, West of Iran. Methods: A total of 200 doogh samples consisted of 150 commercial samples, including five different brands and also 50 homemade samples were purchased randomly from mark...

In times of reducing product development cycles and greater economical, safety and ecological requirements on aircraft structures innovative aircraft configurations with new materials and new structural design concepts become more and more important. Although their positive impact on the conventional pre-design methods come to their limits and to an appropriate tools for design and evaluation t...
