The use of authoring tools has become a valuable trend for the fast development of Augmented Reality (AR) applications in industrial organizations. However, most of current AR authoring tools are actually programming interfaces that are exclusively suitable for programmers, and they do not provide advanced visual effects. In this paper, we propose an easy-to-use AR authoring tool oriented to th...

The problem of assessing occupational exposure using the mean of a lognormal distribution is addressed. The novel concepts of generalized p-values and generalized confidence intervals are applied for testing hypotheses and computing confidence intervals for a lognormal mean. The proposed methods perform well, they are applicable to small sample sizes, and they are easy to implement. Power studi...

Micromagnetic NDT techniques like the measurement of the magnetic Barkhausen noise, the incremental permeability and the harmonic analysis of the tangential magnetic field allow deriving inspection procedures to online monitoring and control machinery parts and components in production processes in order to characterize mechanical properties like hardness, hardening depth, yield and tensile str...

context despite advancements in the science of surgery, minimizing bleeding from parenchymal tissue of the liver continues to be one of the challenges surgeons are facing to protect patients’ lives. however, the number of surgeries needing incisions in the liver tissue, e.g. metastatectomy, is constantly increasing. conclusions the excessive blood loss and the long time needed to control the bl...

The digitalization of real-world objects is of vital importance in various application domains. This method is especially applied in industrial quality assurance to measure the geometric dimension accuracy. Furthermore, geometric models are the very foundation of contemporary three-dimensional computer graphics. In addition to create new models by using a modeling suite, the use of 3D laser sca...

This paper describes a circular economy process based on environmentally and economically sustainable procedures which was applied to the sector of olive oil processing on an industrial scale. Olea europaea L. tissues and by-products represent a renewable and low-cost source of polyphenols, in particular hydroxytyrosol (HTyr), a naturally occurring compound well known for its biological propert...

oral antiplatelet agents, and anticoagulant therapy as appropriate. However, intravenous therapy with glycoprotein IIb/IIIa receptor blockers as well as -blockers, statins and probably ACE inhibitors are underused. Furthermore, the coronary revascularization procedures are not used as often as recommended in recent guidelines. In particular, access to such procedures should be improved for pati...

Project scheduling is the part of project management that deals with determining when intime to start (and finish) which activities and with the allocation of scarce resources to theproject activities. In practice, virtually all project managers are confronted with resourcescarceness. In such cases, the Resource-Constrained Project Scheduling Problem (RCPSP)arises. This optimization problem has...

Software production problems have forced industrial organisations producing embedded systems to assess and change the disciplines used to manage the software process. The development of software configuration management (SCM) is one of the solutions for problems concerning new product features. SCM is also one of the software processes that requires improvements. The importance of SCM is clearl...

conclusion metallic stent placement is a safe and effective procedure for salvage of native hemodialysis fistula after unsuccessful balloon angioplasty. results twenty-one stents were applied. the anatomical and clinical success rate was 100%. seventeen additional interventions were done for 11 (55%) patients due to stent thrombosis or stenosis during follow-up. our 1- and 2-year secondary pate...
