We report radial velocity (RV) measurements of the G-type subgiants 24 Sextanis (= HD 90043) and HD 200964. Both are massive, evolved stars that exhibit periodic variations due to the presence of a pair of Jovian planets. Photometric monitoring with the T12 0.80 m APT at Fairborn Observatory demonstrates both stars to be constant in brightness to 0.002 mag,(More)
Industrial automation is currently on the cusp to the application of distributed systems based on distributed intelligence enabling distributed decision making within control. As one main technology within this field IEC 61499 based function block systems would be applied. But the usage of function block systems may cause problems which have to be avoided(More)
The paper presents the design and implementation of an innovative Integrated Development Environment, developed within the ongoing European Research Project TORERO, to model and design reusable distributed control systems (DCS). This project proposes an architecture which relies on a development environment based on the Eclipse tool and the emerging(More)
BACKGROUND Quality of life (Qol) is an increasingly used outcome measure in dementia research. The QUALIDEM is a dementia-specific and proxy-rated Qol instrument. We aimed to determine the inter-rater and intra-rater reliability in residents with dementia in German nursing homes. METHODS The QUALIDEM consists of nine subscales that were applied to a(More)
BACKGROUND The QUALIDEM is a dementia-specific Quality of life (Qol) instrument that is recommended for longitudinal studies and advanced stages of dementia. Our study aimed to develop a user guide for the German version of the QUALIDEM and to determine the item distribution, internal consistency and inter-rater reliability (IRR) of the German QUALIDEM.

BACKGROUND Person-centered care (PCC) is a widely recognized concept in dementia research and care. Dementia Care Mapping (DCM) is a method for implementing PCC. Prior studies have yielded heterogeneous results regarding the effectiveness of DCM for people with dementia (PwD). We aimed to investigate the effectiveness of DCM with regard to quality of life(More)
We present an analysis of ∼5 years of Lick Observatory radial velocity measurements targeting a uniform sample of 31 intermediate-mass (IM) subgiants (1.5 M * /M 2.0) with the goal of measuring the occurrence rate of Jovian planets around (evolved) A-type stars and comparing the distributions of their orbital and physical characteristics to those of planets(More)
