    Intention-Based Prediction for Pedestrians and Vehicles in Unstructured Environments

    Abstract anzeigen

    Motion prediction for holonomic objects in unstructured environments is an ambitious task due to their high freedom of movement compared with non-holonomic objects. In this paper, we present a method for inferring the future goal of holonomic objects by a heuristic generation of target points (tp) and following discriminating decision making. The target points are generated, in a manner that covers the most common motion hypotheses like following or staying, safety relevant motion hypotheses like crossing future ego trajectories or the movement to special points of interest, e.g. gained from a map. Subsequently, for each considered object a trajectory to the inferred target point will be planned. Finally, the uncertainty of the trajectory is estimated by applying a Kalman Filter with a dynamically adjusted process noise matrix. An additional benefit of this concept is its ability to cope with a different quality of context knowledge, so it can produce sound results even at poor structured environments.

    Perceived Health-Related Quality of Life in Women with Vulvar Neoplasia: A Cross Sectional Study

    International Journal of Gynecological Cancer, vol. 26, no. 7, pp. 1313-1319

    2016

    DOI: 10.1097/IGC.0000000000000770

    Objective The aim of the study was to determine health-related quality of life (HRQoL) of women with surgically treated vulvar intraepithelial neoplasia (VIN) and vulvar cancer (VC) during the first week after hospital discharge. Further objectives were to investigate differences between women with VIN and VC as well as to examine whether correlations exist between women’s symptom experience and HRQoL. Methods This cross-sectional study was conducted in 8 hospitals in Germany and Switzerland. Women with VIN and VC rated HRQoL with the validated German Short-Form 36. Differences between HRQoL in women with VIN and VC were tested with Wilcoxon rank-sum score. The WOMen with vulvAr Neoplasia (WOMAN) - Patient reported Outcome (PRO) self-report instrument was used to measure women’s symptom experience. Correlations between symptoms and HRQoL were calculated using Spearman correlation coefficient. Results Women with VIN and VC (n = 65) reported lower HRQoL in physical aspects (Physical Component Summary [PCS], 34.9) than that in mental aspects (Mental Component Summary, 40.5). Women with VC had lower HRQoL than women with VIN, as manifested by significant differences concerning the dimensions of “physical functioning” and “role-physical.” “Difficulties in daily life” as a distressing symptom correlated with MCS and PCS. Wound-related symptoms correlated with PCS and psychosocial symptoms/issues with MCS. Conclusions Analysis showed that women with vulvar neoplasia reported lower HRQoL in the physical and mental dimensions 1 week after discharge than comparable studies referring to months or years after surgery. Health-related quality of life is influenced by physical impairment because physical symptoms are prevalent 1 week after discharge. Patient education should focus on symptom management in an early postsurgical phase to enhance women’s HRQoL.

    Computed Tomography as a Tool for Tolerance Verification of Industrial Parts

    Procedia CIRP, vol. 10, pp. 125-132

    2013

    DOI: 10.1016/j.procir.2013.08.022

    Abstract anzeigen

    Computed tomography (CT) is becoming an important technology for industrial applications, enabling fast and accurate control of manufactured parts. In only a few minutes, a complete 3D model of a part may be obtained, allowing measurements of external and internal features. This paper presents results of tolerance verification of a plastic housing for an insulin pen manufactured by Novo Nordisk A/S. Calculation of measurement uncertainties was taken into account in decision making regarding the specified tolerance limits. Variables in terms of CT systems, data sets, and evaluation software are considered in this study.

    A study on evaluation strategies in Dimensional X-ray computed tomography by estimation of measurement uncertainties

    International Journal of Metrology and Quality Engineering, vol. 3, no. 2, pp. 107-115

    2012

    DOI: 10.1051/ijmqe/2012011

    Abstract anzeigen

    Computed tomography has entered the industrial world in 1980’s as a technique for non-destructive testing and has nowadays become a revolutionary tool for dimensional metrology, suitable for actual/nominal comparison and verification of geometrical and dimensional tolerances. This paper evaluates measurement results using different measuring strategies applied in different inspection software packages for volume and surface data analysis. The strategy influence is determined by calculating the measurement uncertainty. This investigation includes measurements of two industrial items, an aluminium pipe connector and a plastic toggle, a hearing aid component. These are measured using a commercial CT scanner. Traceability is transferred using tactile and optical coordinate measuring machines, which are used to produce reference measurements. Results show that measurements of diameter for both parts resulted in smaller systematic errors compared to distance and height measurements. It was found that uncertainties of all measurands evaluated on surface data were generally greater compared to measurements performed on volume data.

    An integration of microoptical components to three-dimensional systems is of interest for optical information processing as well as for optical interconnections. Polymethyl methacrylate (PMMA) is a suitable substrate material, because microprisms, beamsplitters and microlenses can be integrated monolithically in the same substrate by deep proton irradiation. The microcomponents can be combined to compact microoptical imaging systems which are easy to align. The fabrication method and the imaging properties of this system are discussed.

    Application of three-dimensional micro-optical components formed by lithography, electroforming, and plastic molding

    Applied Optics, vol. 3232, no. 92, pp. 6464-6469

    Abstract anzeigen

    Micro-optics is usually associated with planar waveguides or integrated optical circuits. In this case the propagation of light is restricted to one or two dimensions, and the three-dimensional nature of light propagation is disregarded. We present a method of fabricating three-dimensional micro-optical components by the so-called LIGA process, a lithography, electroforming, and plastic molding process in which poly(methyl methacrylate) is structured by high-energy synchrotron radiation. We demonstrate an experimental system of image formation that uses microprisms and microlenses for a three-dimensional microintegration of optical components.
