TY - CHAP A1 - Höfig, Kai T1 - FDTA–A Tool Chain for Failure-Dependent Timing Analysis T2 - Proc. of the 11th International Workshop on Worst-Case Execution Time Analysis N2 - Embedded real-time systems are growing in complexity, which goes far beyond simplistic closedloop functionality. Current approaches of worst-case execution time (WCET) analysis are used to verify deadlines of such systems, especially when they are safety critical. These approaches calculate or measure WCET as a single value that is expected as an upper bound for a system's execution time. Overestimations are taken into account to make this upper bound a safe bound, but modern processor architectures with caches, multi-threading, and instruction pipelines often expand those overestimations for safe upper bounds into unrealistic areas. Some approaches try to overcome this problem by calculating multiple upper bounds and argue that each single upper bound will hold for a certain probability (probabilistic worst-case execution time). Even though some of them tackle the problem of obtaining reliable probabilistic values for such upper bounds, more effort is required. Therefore, we present in this paper how probabilities of safety analysis models can be combined with elements of system development models to calculate a probabilistic worst-case execution time. This approach can be applied to systems that use mechanisms belonging to the area of fault tolerance, since such mechanisms are usually quantified in safety analyses to certify the system as being highly reliable or safe.

N2 - The growing complexity of safety-critical embedded systems is leading to an increased complexity of safety analysis models. Often used fault tolerance mechanisms have complex failure behavior and produce overhead compared to systems without such mechanisms. The question arises whether the overhead for fault tolerance is acceptable for the increased safety of a system. Manually modeling the timing behavior is cost intensive and error prone. Current approaches of safety analysis and execution time analysis are not able to reflect the timing behavior of complex mechanisms according to failures. In this paper, we describe an approach that combines safety analysis models with execution times to extract different execution times for different failure conditions. This provides a detailed view on the safety behavior in combination with the produced overhead and allows to find and certify appropriate fault tolerance mechanisms.

A1 - Gibbs, Barry T1 - Point and transfer mobility of point-connected ribbed plates JF - Journal of Sound and Vibration N2 - The work reported in this paper addresses the problem of structure-borne sound transmission between vibrating sources and ribbed-plate receiver structures. Vibrating sources, such as pumps, motors, fans, etc., transmit vibro-acoustic power, causing noise complaints by occupants in cars, trains, aircraft, buildings and/or material fatigue and damage. The transmission process is complicated in that sources transmit power through several contacts and by up to six components of excitation at each contact. The structure-borne sound power is a function of source activity, source mobility and receiver mobility, and all three quantities must be known to some degree. For non-homogeneous receiver structures, such as thin-plate cavity constructions or lightweight framed constructions, the sheathing plates are typically fastened to the framing members using bolts, screws or spot-welded joints. Hence the resulting system is a point-connected ribbed plate structure and the receiver mobility is expected to vary significantly with position. Since measured receiver data seldom is available for prediction purposes, a method of estimating the point and transfer mobility of point connected ribbed plates is required. In this paper, an approximate approach, based on substitution forces, is described. The model uses infinite beam and infinite plate behaviour as input quantities. Estimates of point and transfer mobility are compared with measured results using a timber joist floor construction as an example.

Design: Multi-centre cohort study. Patients: A total of 397 patients (50% female, mean age 63 years) from 5 hospitals in Austria, Switzerland and Germany. Methods: A semi-structured questionnaire was used to assess patient goals and goal achievement. Overall functioning from the patients' and health professionals' perspective was assessed on a numerical rating scale. Improvement in functioning was calculated using a residualized gain score. Association between goal achievement and improvement in overall functioning was assessed with logistic regression. Results: A total of 397 patients reported achievement of at least 1 goal. Eighty-eight percent of the goals were translated into categories of the ICF. Logistic regression analyses revealed significant association between goal achievement and overall functioning. Conclusion: The ICF might be useful to identify and structure patient's goals in acute hospital care. The association between goal achievement and improved functioning underlines that it is essential to involve the patient in the process of planning rehabilitation interventions in acute hospitals.

Several studies have examined the independent effects of single diseases; however, little research has focused on interaction between diseases. The purpose of this study was to assess the impact of six self-reported major conditions and their combinations on HRQL measured by the EQ-5D. Methods The EQ-5D was administered in the population-based KORA-Age study of 4,565 Germans aged 65 years or older. A generalised additive regression model was used to assess the effects of chronic conditions on HRQL and to account for the nonlinear associations with age and body mass index (BMI). Disease interactions were identified by a forward variable selection method. Results The conditions with the greatest negative impact on the EQ-5D index were the history of a stroke (regression coefficient -11.3, p < 0.0001) and chronic bronchitis (regression coefficient -8.1, p < 0.0001). Patients with both diabetes and coronary disorders showed more impaired HRQL than could be expected from their separate effects (coefficient of interaction term -8.1, p < 0.0001). A synergistic effect on HRQL was also found for the combination of coronary disorders and stroke. The effect of BMI on the mean EQ-5D index was inverse U-shaped with a maximum at around 24.8 kg/m2. Conclusions There are important interactions between coronary problems, diabetes mellitus, and the history of a stroke that negatively affect HRQL in the older German population. Not only high but also low BMI is associated with impairments in health status.

Peter Toennies Festschrift N2 - Electronic spectra of molecules doped into superfluid 4He nanodroplets reveal important details of the microsolvation in superfluid helium. The vibrational fine structure in the electronic spectra of phthalocyanine derivatives and pyrromethene dye molecules doped into superfluid helium droplets have been investigated. Together with previous studies on anthracene derivatives [J. Chem. Phys.2010, 133, 114505] and 3-hydroxyflavone [J. Chem. Phys.2009, 131, 194307], the line shapes vary between two limiting cases, namely, sharp Lorentzians and nonresolved vibrational fine structure. All different spectral signatures are initiated by the same effect, namely, the change of the electron density distribution initiated by the electronic excitation. This change can be quantified by the difference of the electrostatic moments of the molecule in the electronic ground state and the corresponding Franck–Condon point in the excited state. According to the experimental data, electronic spectroscopy suffers from drastic line broadening when accompanied by significant changes of the charge distribution, in particular, changes of the dipole moment. Vice versa, the vibrational fine structure in electronic spectra of molecules doped into helium droplets is highly sensitive to changes of the electron density distribution.

T1 - Measuring Functioning in People with Fibromyalgia (FM) Based on the International Classification of Functioning, Disability and Health (ICF)—A Psychometric Analysis JF - Pain Practice N2 - Objectives: Instruments to assess functioning in patients with FM vary considerably in their content and are often symptom‐specific. This study aimed to examine whether it is feasible to construct a psychometric‐sound clinical instrument to measure functioning in FM based on the Brief ICF‐Core‐Set for chronic widespread pain (CWP). Methods: Two hundred and fifty six people with FM completed the Brief ICF‐Core‐Set. The Rasch model was used for analysis. Once ordering of response options of ICF categories was ensured, the following properties were studied: fit of the ICF categories to the Rasch model, the targeting between ICF categories and a person’s abilities, unidimensionality, and reliability. Results: Six ICF categories were rescored due to disordered thresholds. Five ICF categories were removed due to high model‐misfit and differential item functioning (DIF) for gender. Scores from 46 participants were excluded due to extreme scores. The ICF categories included display consistency with an underlying unidimensional construct, are free of DIF for age, disease duration and gender, display excellent overall reliability, and cover a range of functioning difficulties. Conclusions: This study illustrates that it is possible to measure functioning as a unidimensional construct based on selected ICF categories from the components body functions, as well as activities and participation of the Brief ICF‐Core‐Set for CWP in patients with FM.
