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 ...

OBJECTIVES To describe the characteristics of randomised controlled trials supported by the main non-commercial sources of funding in the United Kingdom between 1980 and 2002. DESIGN Descriptive survey. SETTING Randomised controlled trials funded by the Medical Research Council, NHS research and development programme, Department of Health, Chief Scientist Office in Scotland, and medical res...

Summary results of the assessment of new tools for the generation of reconfigurable screen media (ShapeShifting media) and of eight experimental ShapeShifting screen media productions covering genres including news, documentary and drama, are presented from the project New Millennium, New Media. The new tools for creating interactive and reconfigurable narratives depend upon a Narrative Structu...

The use of Technology Readiness Levels (TRLs) as a tool in assessing acquisition and development program risk has steadily increased over the past several years. There is considerable evidence to support the utility of using TRLs as part of a risk assessment, but there are some difficulties in using TRLs with software, especially Commercial-Off-The-Shelf (COTS) software technology and products....

As the prevalence of overweight and obesity has been increasing in South Korea, it is critical to better understand possible associations between environmental surroundings and general health status. We characterize key health test readings and basic demographic information from 10,816 South Koreans, obtained from two Ubiquitous Healthcare (U-Healthcare) centers that have distinct surrounding n...
