    New Inverse Kinematics Algorithms Combining Closed Form Solutions with Nonlinear Optimization for Highly Redundant Robotic Systems

    No full text
    This paper presents inverse position kinematics algorithms with real time capability for Justin, a robotic system with high redundancy and many degrees of freedom. The combination of closed form solutions for parts of the kinematic chain embedded in a nonlinear equation solver is shown to be advantageous. The algorithms are evaluated with the DLR service robot Justin both in simulation and reality. Calculation times of 1 ms are achieved, including various optimization criteria for redundancy resolution. In case only a single arm with 7 DoF is considered, fast calculation time of 250 s is reached. With inclusion of an iterative step, reachability can be shown in more than 99% of the calculations regardless of the initial guess. The problem of weighting in multi-criteria optimization problems remains, though in the chosen approach the tool tip position is never compromised by other criteria due to the partially closed form solution. The presented algorithm can be applied to inverse position kinematics for all manipulators with serial or tree structure and redundant joints in case closed form solutions are available for parts of the kinematic chain

    Endogenous Fixprices and Sticky Price Adjustment of Risk-averse Firms

    No full text
    A risk-averse price-setting firm which knows the quantity demanded at the status quo price but has imperfect information otherwise may choose not to change it although an otherwise identical risk-neutral firm would do so, provided the variance of the firm's subjective probability distribution over quantities demanded as a function of price displays a kink at the status quo. This is equivalent to risk aversion of order one. When no such endogenous fixprice exists, the size of price adjustment still tends to zero as risk aversion tends to infinity, and to any arbitrarily small menu cost there exists a degree of risk aversion so that the firm will not adjust.fixed prices, price adjustment, risk aversion, menu cost

    Gastro-esophageal reflux disease (GERD) is a common disorder that affects an estimated 5 % to 7 % of the global population. Management of GERD often poses a number of challenges. In this article, the author presents a number of management modalities for this condition.peer-reviewe

    La place de la guerre de 1914-1918 dans l'histoire culturelle de l'Allemagne

    The place of the 1914-1918 war in the cultural history of Germany, Gerd Krumeich. Through his study of war accounts and memories, the author analyses the impact of the war experience on German culture in its individual as well as its collective aspects. That impact brought about the continuation and the diffusion of militarism and nationalism in much of the German society of the 1920s and 1930s.Krumeich Gerd.

    Johannsen, M. and Brunner, G., 1994. Solubilities of the xanthines caffeine, theophylline and theobromine in supercritical carbon dioxide. Fluid Phase Equilibria, 95: 215-226. An apparatus for the experimental determination of the equilibrium solubilities of solids in dense gases is described. Determination of solubilities has been performed by using a static analytical method with direct coupling of an equilibrium cell to a supercritical fluid Chromatographic (SFC) system. The solubilities of caffeine, theophylline and theobromine in supercritical carbon dioxide were measured at different temperatures (313, 333 and 353 K) and over a pressure range of 20-35 MPa. Although the chemical structures of the xanthines are very similar, their solubilities in supercritical carbon dioxide vary substantially. The solubilities of caffeine in CO2 are one order of magnitude higher than those of theophylline and two orders of magnitude higher than those of theobromine. Solubility values obtained in this work are compared with published data. Reasons for observed differences are discussed

    Augmenting a pH Medical Study with Wearable Video for Treatment of GERD

    In this paper we present an augmentation to the wearable computers typically used to determine if a patient is a candidate for surgery to correct problems associated with Gastroesophageal Reflux Disease (GERD). A wearable camera was used by the first author while participating in a 24–hour stomach acid pH study. After the study’s conclusion, an examination of the captured video and pH record revealed some results that allowed the first author to avoid many of the activities that result in symptoms related to GERD. 1 GERD and Medical Testing Gastroesophageal Reflux Disease is a medical condition that affects 2 % of the adult population of the United States. GERD refers to the reflux of stomach acid into the esophagus and can lead to complications such as esophageal cancer and lung damage. The most common symptom of GERD is heartburn. Typical treatments for GERD include diet modification and medication; however, for some patients these treatments may prove ineffective, and the patient may be evaluated for more drastic measures such as surgery. If surgery to correct GERD is considered an option, the patient usually undergoes a 24 – or 48–hour pH study to measure the percentage of time that the patient is in reflux during normal daily activities. In the 24–hour study, a pH probe is inserted into the subject’s nose and lowered through the esophagus to a position above the stomach. Since the probe is attached to a line that is retained in the patient’s nose and throat, several pH sensors can be placed at varying locations along the patient’s esophagus. The probe is attached to a wearable computer which records the patient’s pH levels for 24 hours. The patient typically uses the wearable computer to record times of meals, periods spent in a supine position (e.g. sleeping), and occurrences of symptoms.
