Constraint-based Model Predictive Control for holonomic mobile manipulators

In this paper, a controller based on constrained optimization for tracking problems in mobile manipulation is presented. A Model Predictive Control problem is set and solved online, allowing to deal with dynamic scenarios and unforeseen events. Besides acceleration, velocity and position constraints, collision avoidance constraints for the mobile base and the arm and Field-of-View constraints have been enforced and extended over the prediction horizon. Navigation performance has been improved by including an additional goal, derived from the classical vortex field approach, to the MPC problem. An experimental validation on a KUKA youBot mobile manipulator has been carried out, showing the online applicability of the presented approach

An avidin/biotin ELISA for the measurement of serum and secretory IgD.

This paper describes an improved microtiter solid-phase enzyme immunoassay for the determination of serum and secretory IgD. Use of the interaction between biotinylated anti-human IgD and horseradish peroxidase(HRP)-avidin conjugate permits quantitation of human IgD in the range of 1-64 ng/ml. IgD was detected in all samples of serum, saliva and nasal secretions of 28 normal adults. In only one subject both serum and secretory IgD were undetectable. The mean concentration of serum IgD determined by this assay is similar to that reported by other authors using radioimmunoassay. The assay described is not only rapid and inexpensive but at least as sensitive as the radioimmunoassays usually employed for quantitation of IgD

Optimal placement of spots in distributed proximity sensors for safe human-robot interaction

Industrial robots are today separated from human workers by means of safety barriers, that protect humans from the risk of collisions. This separation has a clear negative influence on diffusion of robotic technology in shopfloors. On the other hand the removal of protective barriers gives rise to safety issues, that can be addressed with a combination of approaches, including sensor based reactive control. In this paper a distributed proximity sensor, to be mounted on the links of the manipulator, is presented. The optimal placement of the spots of such sensor is discussed, taking into account detection capabilities and safety enhancement. Experiments developed on an ABB IRB 140 robot using off-the-shelf infrared distance sensors as spots are presented

Role of IgE in the pathogenesis of milk allergy in infancy: reassessment by a new ELISA technique.

An ELISA technique using labelled antigen for the determination of cow's milk specific IgE in serum is described. The use of labelled antigen, rather than labelled antibody as in the RAST, permits avoidance of interference by antibodies other than IgE, such as IgG, at times responsible for a negative RAST. The results obtained with the 2 techniques in 43 infants with a positive cow's milk challenge showed a positive RAST in 28%, a positive ELISA in 35% and a positive RAST or ELISA in 42%. These findings suggest that the use of both ELISA and RAST permits in vitro diagnosis of cow's milk allergy in more patients than either test alone
