In continuous processing, healthcare systems are affected by their constituent elements, themselves modified with each system change. To secure and optimize the system of care, collaboration between levels is necessary. Almost no documented experience to better coordination of levels of care in the Belgian system is available. To improve the quality of care, the system needs collaborative coordination between stakeholders. Good coordination improves the quality of patient care, it makes quality more efficient and optimal care. This coordination between care lines must be collaborative. Interactional communication is the founding element of inter-professional collaboration. A good self-esteem improves the relationship between actors in the health system and supports the initiatives and adaptability. It contributes therefore to an increase of the quality of care. The interactional Local Health System promotes cooperation in the relevant health network. Consultation and coordination between the actors involved and motivated bring care quality and operational solutions. This dynamic modality of exchanges appears fruitful as participants continue to meet and coordinate care, even after the official end of the action-research. The climate became conducive to solving real problems through the skills developed in the LHS.展开更多

It is shown that the time-resolved cooperative vibronic spectroscopy is a very useful technique for the determination of the ligand type and ligand number for different coordination groups. Coordination configuration of arginine with Tb3+ in solutions with different pH values was studied. It demonstrates that the carboxy1 of arginine can replace H2O to coordinate with Tb3+ and the coordination number of carboxyl increases with the increase of pH value of the solutions.展开更多

However, if channel is time-varying, the channel difference would cause codeword mismatch between transmitter and receiver, which leads to performance degradation. In this paper, a linear interpolation method is proposed for TDD-CoMP system to estimate the uplink channel at the receiver, which would reduce the channel difference caused by time delay and decrease the probability of codeword mismatch between both sides. Moreover, to mitigate severe inter-cell interference and increase the coverage and throughput of celledge users in UDN, a two-codebook scheme is used to strengthen cooperation between base stations (BSs), which can outperform the global precoding scheme with less overhead. Simulations show that the proposed scheme can significantly improve the link performance compared to the global precoding scheme.展开更多

On the condition of the coordination game, the enterprises may be stuck on the non-efficient equilibrium status, which becomes an important problem that must be considered on cluster supply chains. A symmetrical coordination game model is constituted to describe the competition and cooperation relationship of the same-quality manufacturers on cluster supply chains. The methods of the non-cooperation game theory and the evolutionary game theory are respectively used to analyze the model, whose parameters' influences under each method are then compared. It can be concluded that the analysis of the evolutionary game theory is more realistic and practical. Finally, three approaches are considered to break away from being path-dependence locked-in non-efficient status during this coordination game evolutionary process, which provide the development of cluster supply chains with an effective forecasting and Pareto optimizing method.展开更多

In this paper, a master slave method is proposed to control the motions of multiple mobile robots that cooperatively transport a common object from a start point to a goal point. A noholonomic kinematic model to constrain the motions of multiple mobile robots is built in order to achieve cooperative motions of them, and a “Dynamic Coordinator” strategy is used to deal with the collision avoidance of the master robot and slave robot individually. Simulation results show the robustness and effectiveness of the method.展开更多

It analyses the reasons for imbalance between the rural credit cooperatives and rural economic relations,including the direct reason (loss of function of the rural credit cooperatives) ,the fundamental reason (restricted economic development of agriculture and countryside and relative pauperization of farmers) ,and the deep-seated reason (sluggish rural economic development) . Corresponding countermeasures and proposals are put forward for promoting balanced development of the rural credit cooperatives and rural economy as follows: first, deepen reform of the rural credit cooperatives,strengthen the function of the rural credit cooperatives in serving the needs of agriculture; second, speed up economic development in rural areas,eliminate the economic constraints for the development of the rural credit cooperatives; third,transform the development pattern and the development strategies,foster the macro-institutional environment for balanced development of rural credit cooperatives and rural economy.展开更多
