The present contribution deals with the design of a monolithic weighing cell for the realization of a further developed mass comparator for 1kg-standards. The monolithic structure with semicircular flexure hinges is approximated by a rigid body model. The resulting equations can be used as design equations...

We present two versions of a compact spectrograph optical scheme based on aberration-corrected concave holographic grating. It is shown that performance of a widely-known flat-field spectrograph scheme can be significantly improved by means of use of a curved detector and introduction of an additional...

Sheet metal products can be found in almost all household-, electrical appliances, vehicles and industrial machines. One of the widely spread methods of sheet metal processing is the shearing process which separates large sheets into smaller sections (stampings) for subsequent operations. Cutting edges...
