A pre-screening procedure with a number of candidate Human-Machine-Interaction solutions (visual, auditory and haptic) for the concept of Safe Speed and Safe Distance was carried out. Two groups of about 30 test persons participated in the two-phase test procedure. Eleven candidate visual displays for speed information and ten alternatives for distance warning as well as twelve auditory warning so
We show how one can back out implied forward volatility term structures from credit default swap spreads. Such forward stock volatility term structures are useful for instance in forward start option pricing. We find the term structure to be downward-sloping, and the credit market's volatility forecasts tend to vary more across time than across maturities. Long-term volatility expectations, in tur
E-procurement — e-business mechanisms deployed on procurement — offers many recent and innovative methods that can improve procurement in different ways. The key challenge of e-procurement, however, is how to apply the various e-procurement applications in such a way that they improve the procurement practice and sourcing strategy of a company. There is a demand for an investigation that scrutiniz
Design rules for optimal feedforward controllers with lead-lag structure in the presence of measurable disturbances are presented. The design rules are based on stable first-order models with time delays, FOTD, and are optimal in the sense of minimizing the integrated-squared error. The rules are derived for an open-loop setting, considering a step disturbance. This paper also discusses a general
As chips are getting increasingly complex, there is no surprise to find more and more built-in DFX. This built-in DFT is obviously beneficial for chip/silicon DFX engineers; however, board/system level DFX engineers often have limited access to the build in DFX features. There is currently an increasing demand from board/system level DFX engineers to reuse chip/silicon DFX at board/system level. T
Introduction: The objective of this study was to describe the longitudinal cognitive outcome in Alzheimer’s disease (AD) and analyze factors that affect the outcome, including the impact of different cholinesterase inhibitors (ChEI). Methods: In an open, three-year, nonrandomized, prospective, multicenter study, 843 patients were treated with donepezil, rivastigmine, or galantamine in a routine cl
To the extent that increased urinary protein excretion is an indicator of alterations of the glomerular capillary wall (GCW) and appearance of tubulointerstitial damage, proteinuria can be a good marker of the overall severity of the glomerular and tubulointerstitial damage, and therefore, the prognosis of glomerular diseases. Studies I, II, and III show that it is the type of proteinuria, rather
A classical solution for matching two image patches is to use the cross-correlation coefficient. This works well if there is a lot of structure within the patches, but not so well if the patches are close to uniform. This means that some patches are matched with more confidence than others. By estimating this uncertainty more weight can be put on the confident matches than those that are more unce
This paper presents experimental data on investigation of novel flameless combustors in application of gas turbine engines at atmospheric conditions. Flameless combustion is characterized by distributed flame and even temperature distribution under the conditions of high preheat air temperature and sufficient large amount of recirculating low oxygen concentration exhaust gas. Extremely low emissio
The proposed MAX IV facility is meant as a successor to the existing MAX-lab. The accelerator part will consist of three storage rings, two new ones operated at 3 and 1.5 GeV respectively and the existing 700 MeV MAX III ring. The two new rings have identical lattices and are placed on top of each other. Both these rings have a very small emittance, 0.86 and 0.4 nm rad respectively, and offer sync
To manage increasingly complicated 3D city models, a framework based on NoSQL database is proposed in this paper. The framework supports import and export of 3D city model according to international standards such as CityGML, KML/COLLADA and X3D. We also suggest and implement 3D model analysis and visualization in the framework. For city model analysis, 3D geometry data and semantic information (s
We consider distributed model predictive control (DMPC) where a sparse centralized optimization problem without a terminal cost or a terminal constraint set is solved in distributed fashion. Distribution of the optimization algorithm is enabled by dual decomposition. Gradient methods are usually used to solve the dual problem resulting from dual decomposition. However, gradient methods are known f
