Numerical and Experimental Evaluation of Springback in Advanced High Strength Steel

The automotive industry is using more and more of Advanced High Strength Steel in order to reduce the weight of the car. Since this will generate more springback, it is of vital importance to be able to predict the amount of springback in the parts. Otherwise, many late changes have to be made in order to fit the parts in their position. In order to increase the ability to understand and test the

Inactivation of TGF beta signaling in neural crest stem cells leads to multiple defects reminiscent of DiGeorge syndrome

Specific inactivation of TGFbeta signaling in neural crest stem cells (NCSCs) results in cardiovascular defects and thymic, parathyroid, and craniofacial anomalies. All these malformations characterize DiGeorge syndrome, the most common microdeletion syndrome in humans. Consistent with a role of TGFbeta in promoting non-neural lineages in NCSCs, mutant neural crest cells migrate into the pharyngea

Reducing Moisture Transients in the Paper-Machine Drying Section with the Mid-ranging Control Technique

A new control strategy using feedback control has been developed for the multi-cylinder paper dryer configuration to reduce moisture transients in the drying section. The air system in the blow boxes was used to control the fast moisture transients in the paper machine. The new control system was combined with a previously developed physical model and was then compared with a conventional moisture

Multiscale detection of transient evoked otoacoustic emissions

This paper presents a unified approach to multiscale detection of transient evoked otoacoustic emissions (TEOAEs). Using statistical detection theory, it is shown that the optimal detector involves a time windowing operation where the window can be estimated from ensemble correlation information. The detector performs adaptive splitting of the signal into different frequency bands using either wav

Diagnostic accuracy of the neurological upper limb examination II: Relation to symptoms of patterns of findings

Background: In a sample of patients in clinical occupational medicine we have demonstrated that an upper limb neurological examination can reliably identify patterns of findings suggesting upper limb focal neuropathies. This further study aimed at approaching the diagnostic accuracy of the examination. Methods: 82 limbs were semi-quantitatively assessed by two blinded examiners ( strength in 14 in

Review of Birgit Stolt, Martin Luthers Rhetorik des Herzens. Tübingen 2000.

Luthers kombination av Guds-ords-mystik och kallelsemedvetande blir så tydlig att den just därför varit svår att förstå. Stolt gör upp med vanföreställningar som att retorik skulle utesluta spontanitet. Hon utgår från språkvetenskapliga iakttagelser: Luthers latinska och tyska språkanvändning står i intensivt beroende av varandra, och hans nyskapande insatser för det tyska språket kan inte isolera

Disentangling genetic variation for resistance and tolerance to infectious diseases in animals

Hosts can in principle employ two different strategies to defend themselves against parasites: resistance and tolerance. Animals typically exhibit considerable genetic variation for resistance (the ability to limit parasite burden). However, little is known about whether animals can evolve tolerance (the ability to limit the damage caused by a given parasite burden). Using rodent malaria in labora

Smart people that make simple heuristics work

In order to evaluate the success of simple heuristics we need to know more about how a relevant heuristic is chosen and how we learn which cues are relevant. These meta-abilities, we believe, are at the core of ecological rationality, rather than the individual heuristics.

Children's needs during hospitalization: an observational study of hospitalized boys.

Twenty-one boys (age range 5 months to 16 years) were followed during their stay at hospital. Total observation time was 120 h. Field notes were made immediately after each observation. These were then transcribed into a narrative text, which was analysed by content analysis. Six categories of needs were identified during non-threatening situations at the hospital: the need for activity, the need

Dynamic response of a constrained axially loaded beam

A dynamic beam system loaded harmonically in the axial direction and constrained in the transverse direction is modelled using different theoretical descriptions. Results from an experimental set-up are compared to calculations using Bernoulli as well as Timoshenko beam theories. Some results from investigations of this beam system unveiling its chaotic nature have earlier been presented, but here
