The performance of an augmentor wing has been examined with a simplified model that consists of a thin airfoil with a jet-augmented flap and a sink located at the hinge of the flap. The analysis is based on a small disturbance theory. The results for the basic configuration, namely the airfoil with a jet-augmented flap, agree very well with those obtained by other authors. It shows that the lift on the airfoil can be increased appreciably with a jet-augmented flap. Suction on the upper surface of the airfoil can also induce additional lift on the system. This induced lift becomes more efficient as the suction slot moves towards the trailing edge. However, the lift decreases slightly as the jet momentum flux increases and the jet becomes more "stiff".

Synchrony is claimed by psychology as a crucial parameter of any social interaction: to give to human a feeling of natural interaction, a feeling of agency [17], an agent must be able to synchronise with this human on appropriate time [29] [11] [15] [16] [27]. In the following experiment, we show that synchrony can be more than a state to reach during interaction, it can be a useable cue of the human’s satisfaction and level of engagement concerning the ongoing interaction: the better is the interaction, the more synchronous with the agent is the human. We built an architecture that can acquire a human partner’s level of synchrony and use this parameter to adapt the agent behavior. This architecture detects temporal relation [1] existing between the actions of the agent and the actions of the human. We used this detected level of synchrony as reinforcement for learning [6]: the more constant the temporal relation between agent and human remains, the more positive is the reinforcement, conversely if the temporal relation varies above a threshold the reinforcement is negative. In a teaching task, this architecture enables naive humans to make the agent learn left-right associations just by the mean of intuitive interactions. The convergence of this learning reinforced by synchrony shows that synchrony conveys current information concerning human satisfaction and that we are able to extract and reuse this information to adapt the agent behavior appropriately.

The purpose of this study is to describe patients' experiences of the quality of care received at a radiotherapy centre. The data were collected using the Good Nursing Care Scale For Patients (GNCS/P), which was modified for this study. Structured questionnaires were handed out in March-May 2004 to 150 adult curative cancer patients attending outpatient radiotherapy at a university hospital in Finland. A total of 135 completed questionnaires were returned. The patients were generally satisfied with the quality of care they received. Among the four quality categories, the highest ratings were given to staff characteristics, and the lowest to the environment. Younger patients, employed patients and those with a higher level of education gave the lowest quality ratings. Improvements are needed primarily in the counselling and education of patients and their relatives. The results of this study provide valuable clues for improving the quality of care in radiotherapy based on patients' expectations.
