MOTIVATION Side-chain positioning is a central component of homology modeling and protein design. In a common formulation of the problem, the backbone is fixed, side-chain conformations come from a rotamer library, and a pairwise energy function is optimized. It is NP-complete to find even a reasonable approximate solution to this problem. We seek to put this hardness result into practical cont...

This paper proposes a way to achieve positioning tasks by visual servoing, for any orientation of the camera, when the desired image of the observed object cannot be precisely described. The object is assumed to be planar and motionless but no knowledge about its shape or pose is required. To simplify the problem, first, we treat the case of a threadlike object and then we show how our approach...

A novel controi method for positioning operations of deformable objects will be presented. In many manipulative operations of deformable objects, it is required to guide multiple points on an object simultaneously. Moreover, the points often cannot be manipulated directly. A model of the manipulated deformable object is essential to perform these operations. It is, however, dificult to build a ...

BACKGROUND A recent multicenter trial demonstrated decreased mortality when patients with acute respiratory distress syndrome were treated with prone positioning (PP). However, the optimal duration of this treatment has not been established. METHODS From May 2010 to August 2013, 15 patients with respiratory failure underwent extended-duration prone positioning (more than 40 h) in the medical-...

Consumer preferences change through time and rms have to adjust their product positioning for their products to continue to be appealing to consumers. These changes in product positioning require xed investments such that rms engage in these repositionings only once in a while. We construct a model that can include both predictable and unpredictable consumer preference changes, and where a rm o...

WiFi positioning plays an increasingly important role in improving performance because good positioning can improve performance in indoor environments without additional devices. It will make use of existing WiFi infrastructure, although this was never designed to do so. Methods that were used for other positioning technologies can be adopted for WiFi. Whether or not these other methods work wi...

The number of casualties and fatalities brought on by road accidents is one the most significant concerns in modern world. Instead dispatching ambulances only at time demand, pre-positioning them can reduce response provide prompt medical attention. Deep learning techniques hold great potential have proven to be essential for problem-solving decision-making field healthcare services. This study...
