- The here presented combination of stereo imaging and elemental mapping with soft X-ray microscopy reveals the spatial arrangement of naturally aqueous colloidal systems, e.g. iron oxides in soil colloid clusters. Changes in the spatial arrangement can be induced by manipulating the sample in-situ and thus be investigated directly and as a function of time.

Tidskriftsartikel (refereegranskat)abstract
- We present a study of multiple sclerosis segmentation algorithms conducted at the international MICCAI 2016 challenge. This challenge was operated using a new open-science computing infrastructure. This allowed for the automatic and independent evaluation of a large range of algorithms in a fair and completely automatic manner. This computing infrastructure was used to evaluate thirteen methods of MS lesions segmentation, exploring a broad range of state-of-theart algorithms, against a high-quality database of 53 MS cases coming from four centers following a common definition of the acquisition protocol. Each case was annotated manually by an unprecedented number of seven different experts. Results of the challenge highlighted that automatic algorithms, including the recent machine learning methods (random forests, deep learning,.), are still trailing human expertise on both detection and delineation criteria. In addition, we demonstrate that computing a statistically robust consensus of the algorithms performs closer to human expertise on one score (segmentation) although still trailing on detection scores.

Tidskriftsartikel (refereegranskat)abstract
- We present a laser plasma based x-ray microscope for the water window employing a high-average power laser system for plasma generation. At 90 W laser power a brightness of 7.4 x 10(11) photons/(s x sr x mu m(2)) was measured for the nitrogen Ly alpha line emission at 2.478 nm. Using a multilayer condenser mirror with 0.3 % reflectivity 10(6) photons/(mu m(2) x s) were obtained in the object plane. Microscopy performed at a laser power of 60 W resolves 40 nm lines with an exposure time of 60 s. The exposure time can be further reduced to 20 s by the use of new multilayer condenser optics and operating the laser at its full power of 130 W.

Agent-based intelligent collaborative care management

Konferensbidrag (refereegranskat)abstract
- The aim of our research is to provide a unified model for the composition and management of consumer care services. We identify design, composition, distribution and management as key stages of this model and propose an Intelligent Collaborative Care Management (ICCM) System as its realisation. The distribution and management stages are implemented as multi-agent systems. Agents in the distribution stage carry out domain-specific negotiation and distribution processes for the assignment of tasks in the care plan. Through the agents in the management stage, we introduce the notion of 'failure prevention' and 'adherence support' in contrast to 'failure recovery' in planning. The key to failure prevention is to identify what has to be carried out to prevent care plan failures. The healthcare domain is used to demonstrate the ICCM system.

Goal-Directed Approach for Process Specification and Service Selection in Customer Life Cycle Management

Bokkapitel (refereegranskat)abstract
- Service selection is the first step in customer life cycle management where services are selected to meet a customer's goals or objectives, personalised to the circumstances of the customer. The aim of this paper is twofold: (1) to develop concepts and algorithms for goal-directed service selection; and (2) to compare and reconcile our goal-directed approach with a service-oriented approach. The proposed goal-directed service selection algorithm is based on a goal-directed domain description that represents the customer objectives and the business processes. We use service component architectures with formalised contractual service process definitions as a software engineering approach to architectural design and realisation of service-oriented architectures (SOA). The comparison aims to understand the relationship between and benefits of a goal-directed approach and a service oriented approach . We use case studies from two complex customer care management domains to demonstrate the concepts. The implemented algorithms are tested in a health care case study.
