Methodology for complexity and cost comparison between subtractive and additive manufacturing processes
This works presents a methodology, along with its software implementation called “Design 2 Cost”, for evaluating the manufacturing cost and complexity of a part built by a subtractive (e.g. milling) or additiv...

Monitoring of adenovirus load in stool by real-time PCR permits early detection of impending invasive infection in patients after allogeneic stem cell transplantation
Invasive adenovirus (AdV) infections are associated with high morbidity and mortality in allogeneic stem cell transplant recipients. We observed that molecular detection of the virus in stool specimens commonl...

A new approach for toolpath programming in Incremental Sheet Forming
Because of involved means and process implementation, toolpath generation is a key topic linked to incremental sheet forming. Process characteristics ask for specifically dedicated toolpaths. This paper firstl...

Measuring supersymmetry
If new physics is found at the LHC (and the ILC) the reconstruction of the underlying theory should not be biased by assumptions about high-scale models. For the map** of many measurements onto high-dimensio...

The afterglow of GRB 050709 and the nature of the short-hard γ-ray bursts
The final chapter in the long-standing mystery of the γ-ray bursts (GRBs) centres on the origin of the short-hard class of bursts, which are suspected on theoretical grounds to result from the coalescence of n...
