Opis:
A simple in situ solution process was developed to produce a mechanically and thermally stable ZnO-carbon nanotube fiber composite. ZnO nanoparticles were homogeneously deposited onto the surfaces of and interstices within CNT fibers (between individual CNTs). X-ray photoelectron spectroscopy and Raman analysis revealed that ZnO nanoparticles contained oxygen vacancy defects and CNT fibers included oxygen containing functional group that strongly interacted with Zn. The strong interaction enhanced the mechanical properties of the composite fibers. The Young modulus (20 GPa) and tensile strength (118 MPa) were enhanced compared to the corresponding values of the pristine CNT fibers. The thermal stability was high up to 880°C and light absorption was enhanced across the UV to near IR region in a ZnO-CNT fiber composite. The electrical conductivity of the composite was high up to 954 S/cm despite semiconductor deposition.

Opis:
The problem of vessel collisions or near-collision situations on sea, often caused by human error due to incomplete or overwhelming information, is becoming more and more important with rising maritime traffic. Approaches to supply navigators and Vessel Traffic Services with expert knowledge and suggest trajectories for all vessels to avoid collisions, are often aimed at situations where a single planner guides all vessels with perfect information. In contrast, we suggest a two-part procedure which plans trajectories using a specialised A* and negotiates trajectories until a solution is found, which is acceptable for all vessels. The solution obeys collision avoidance rules, includes a dynamic model of all vessels and negotiates trajectories to optimise globally without a global planner and extensive information disclosure. The procedure combines all components necessary to solve a multi-vessel encounter and is tested currently in simulation and on several test beds. The first results show a fast converging optimisation process which after a few negotiation rounds already produce feasible, collision free trajectories.

Opis:
Small and inexpensive acceleration sensors, cameras, microphones, micro-mirrors, touch-panels and other products of the MNT industry are the core components of almost every new and innovative electronic appliance. Customer-tailored functions and specifications require a deep involvement of the customer throughout the whole value chain. Often the varying stages of the product engineering flow are carried out by diverse companies (or at least different departments) in different locations. With "time to market" being essential, a fast and effective product engineering approach along with comprehensive software support is required. In this paper we introduce a comprehensive methodology and based on that a concept for a distributed environment for customer-oriented product engineering of MEMS products. The development is currently carried out in an international EU research project.

Opis:
Developing new software components for ship bridges is challenging. Mostly due to high costs of testing these components in realistic environments. To reduce these costs the development process is divided into different stages. Whereas, the final test on a real ship bridge is the last step in this process. However, by dividing the development process into different stages new components have to be adapted to each stage individually. To improve the process we propose a mobile ship bridge system to fully support the development process from lab studies to tests in realistic environments. Our system allows developing new software components in the lab and setting it up on a ship bridge without interfering with the vesselʹs navigational systems. Therefore it is linked to a NaviBox to get necessary information such as GPS, AIS, compass, and radar information. Our system is embedded in LABSKAUS, a test bed for the safety assessment of new e‐Navigation systems.

Healthy Worker Effect
Opis:
Objective: The Paducah Gaseous Diffusion Plant (PGDP) became operational in 1952; it is located in the western part of Kentucky. We conducted a mortality study for adverse health effects that workers may have suffered while working at the plant, including exposures to chemicals. Materials and Methods: We studied a cohort of 6820 workers at the PGDP for the period 1953 to 2003; there were a total of 1672 deaths to cohort members. Trichloroethylene (TCE) is a specific concern for this workforce; exposure to TCE occurred primarily in departments that clean the process equipment. The Life Table Analysis System (LTAS) program developed by NIOSH was used to calculate the standardized mortality ratios for the worker cohort and standardized rate ratio relative to exposure to TCE (the U.S. population is the referent for ageadjustment). LTAS calculated a significantly low overall SMR for these workers of 0.76 (95% CI: 0.72–0.79). A further review of three major cancers of interest to Kentucky produced significantly low SMR for trachea, bronchus, lung cancer (0.75, 95% CI: 0.72–0.79) and high SMR for Non-Hodgkin’s lymphoma (NHL) (1.49, 95% CI: 1.02–2.10). Results: No significant SMR was observed for leukemia and no significant SRRs were observed for any disease. Both the leukemia and lung cancer results were examined and determined to reflect regional mortality patterns. However, the Non-Hodgkin’s Lymphoma finding suggests a curious amplification when living cases are included with the mortality experience. Conclusions: Further examination is recommended of this recurrent finding from all three U.S. Gaseous Diffusion plants.
