Flexible Application-Layer Multicast in Heterogeneous Networks

This work develops a set of peer-to-peer-based protocols and extensions in order to provide Internet-wide group communication. The focus is put to the question how different access technologies can be integrated in order to face the growing traffic load problem. Thereby, protocols are developed that allow autonomous adaptation to the current network situation on the one hand and the integration of WiFi domains where applicable on the other hand

Supporting Behavior Change After AECOPD – Development of a Hospital-Initiated Intervention Using the Behavior Change Wheel

After hospitalization due to acute COPD exacerbations, patient-manageable behaviors influence rehospitalization frequency. This study’s aim was to develop a hospital-ward-initiated Behaviour-Change-Wheel (BCW)-based intervention targeting patients’ key health behaviors, with the aim to increase quality of life and reduce rehospitalization frequency. Intervention development was performed by University Hospital Zurich working groups and followed the three BCW stages for each of the three key literature-identified problems: insufficient exacerbation management, lack of physical activity and ongoing smoking. In stage one, by analyzing published evidence – including but not limited to patients’ perspective – and health professionals’ perspectives regarding these problems, we identified six target behaviors. In stage two, we identified six corresponding intervention functions. As our policy category, we chose developing guidelines and service provision. For stage three, we defined eighteen basic intervention packages using 46 Behaviour Change Techniques in our basic intervention. The delivery modes will be face-to-face and telephone contact. In the inpatient setting, this behavioral intervention will be delivered by a multi-professional team. For at least 3 months following discharge, an advanced nursing practice team will continue and coordinate the necessary care package via telephone. The intervention is embedded in a broader self-management intervention complemented by integrated care components. The BCW is a promising foundation upon which to develop our COPD intervention. In future, the interaction between the therapeutic care team-patient relationships and the delivery of the behavioral intervention will also be evaluated.

Blister tests on thin-walled composite structures at different temperatures

Blister tests are widely used to characterize adhesives on substrates. In this paper, pressurized blister tests are performed at different temperatures between −40 C and 180 C with two different glass fiber-reinforced plastic laminates. The paper examines the influence of surface pretreatment and geometric features of the substrate. The resulting burst pressures vary between 1 bar and 150 bar. Our studies show that the main influences on burst pressures at high temperatures are glass-transition temperature and storage modulus, and at low temperatures brittleness of the epoxy. Surface pretreatment of corundum blasting results in the highest burst pressures. While the gap width has a big impact on burst pressures, gap spacings show little influence
