Kontrola ciągłości wklejenia kotwi linowych jest, podobnie jak w przypadku wklejanych żerdzi kotwiowych, ważnym elementem zapewniania bezpieczeństwa pracy i ochrony przed zawałem stropu w wyrobiskach korytarzowych w podziemiach zakładów górniczych. Wychodząc naprzeciw tym potrzebom, w Głównym Instytucie Górnictwa opracowano metodę identyfikacji ciągłości wklejenia żerdzi kotwiowych w górotworze, natomiast w niniejszym artykule opisano problem oceny jakości wklejenia kotwi linowych.

The control of continuity of rope anchors cementing, similarly as in case of rod anchors cementing, is an important element of providing the work safety of work and protection against roof falls in roadways of underground mines. Facing these needs the Central Mining Institute elaborated a method of identification of continuity of rod anchors cementing in the strata whereas this artilce describes the problem of assessment of the quality of rope anchors cementing.
The planning of therapeutical interventions and the understanding of pathological processes may be improved by providing tools for biomechanical simulation. This article focuses on computational services providing numerical simulations for analysis, prediction and virtual prototyping to the medical sector ("bio-numerics"). Two example problems are discussed: (1) The simulation of distraction osteogenesis using Finite Element Models (FEM): Simulations use highly resolved meshes in order to represent the complex midface structures with sufficient detail. Meshes with 1 mm resolutions typically have 1+ million nodes, so forward models must be computed on high performance computing (HPC) platforms. Pre-operative planning involves "playing" with different what-if scenarios so fast response times are highly desirable in order to provide tools that are accepted in a clinical environment. (2) Intra-operative planning in neurosurgery using inverse biomechanical models: Surgically induced deformations invalidate pre-operatively acquired information about functionally relevant areas. This problem is addressed by non-linear registration of pre-operative functional Magnetic Resonance Imaging (MRI) data to intra-operative MRI data.
