Abstract: A controller design for a dual input single output (DISO) system is applied to a robot for printing layouts at construction sites. The differential drive robot has a separately controlled linear actuator that moves the print head perpendicularly to the fore-aft axis of the robot. The output is the lateral position of the print head; the sum of the position of the linear actuator (faster stage) relative to a reference point on the front of the robot, which is determined by the steering of the robot (slower stage). Both are measurable. The controller coordinates the action of the separately controlled linear actuator and the differential steering to achieve fast convergence and sub-millimeter tracking. Simulations and experimental results demonstrate the effectiveness of the approach.

Abstract: The invention relates to a method for correcting a misalignment of at least one shafting of a powertrain on a test bench, where at least one piezoelectric force sensor is arranged in a path of force via which a force flow can be transmitted between a load unit of the test bench and a drive unit of the powertrain or the test bench during a transmission of power via the shafting, comprising: performing a force measurement in at least one plane and/or perpendicular to the at least one plane which is intersected by a rotational axis of the shafting and may be substantially perpendicular to the rotational axis; analyzing a measured value or a measured value progression of the force measurement for detecting a misalignment of the shafting; determining target values for a position correction of the load unit or the drive unit in order to minimize the misalignment; and outputting the target values.

Abstract: A mobile learning system having (1) a web site which allows a user, typically, a teacher, to gather or import and organize digital educational contents and (2) a software application for use with a tablet, notebook or other portable electronic device associated with a remote user, e.g., a student, which functions to download selected materials from the website. The web site permits a teachers to bundle material for viewing by students on a tablet or notebook device. The web site will allow teachers to locate educational content or upload their own content e.g. e-books, study guides, worksheets and combine them to create units. Units are comparable to chapters of a textbook. These units will be combined to create courses. Through the mobile application, courses containing the individual units will be downloaded to a student's tablet or notebook device. The student will download the application to his device and be able to access the units for his particular course.

Abstract: Silicone resin emulsions especially suitable for hydrophobing gypsum compositions together with H-siloxanes are prepared by hydrolysis and subsequent distillation to an alcohol content of less than 0.1 weight percent. Use of the emulsion with H-siloxanes provides plaster products such as plasterboard of increased hydrophobicity.

Abstract: Aqueous solutions or dispersions of organooligosiloxanes or organopolysiloxanes that include one or more nitrogen-containing side chains and in which a radical containing a polyoxyalkylene unit is bonded to the second Si atom of the chain are suitable for treating fiber materials. A pleasantly soft handle is hereby imparted to the fiber materials, in particular textiles. The novel siloxanes can be obtained by reacting dialkoxysilanes containing substituents having amino groups with cyclic trisiloxanes or tetrasiloxanes, followed by reaction with silanes that contain substituents having polyoxyalkylene units.

Abstract: Organopolysiloxanes in which two polysiloxane chains are bonded via a divalent radical can be obtained by reaction of cyanuric halides with organopolysiloxanes which contain primary amino groups in substituents. The divalent radical contains 1,3,5-triazine rings, to which a halogen atom is still bonded. The organopolysiloxanes thus obtained are suitable for soft handle treatment of fiber materials. In particular, textile sheet-like structures which comprise cellulose fibers can thereby be given a soft handle and improved permanence of the treatment effects with respect to washing processes.
