Mixed Reality is a very useful and powerful instrument for the visualization of processes, including the assembly process. A Mixed Reality based step-by-step furniture assembly application is introduced. On the one hand context related actions are given to the user to install elements. On the other hand an intuitive way for authors to create new MR based assembly instructions is provided. Our g...

This paper describes how mixed reality (MR) technology is applied in the urban renewal process to help mixed groups of stakeholders collaboratively construct, explore and discuss their vision of a particular urban project on site.

In addition to competing through adjustments of tactical variables such as price or the number of ads a product carries, we allow the incumbent to consider changes in its business model. We consider four alternative business models: a subscription-based model; an ad-sponsored model; a mi...

This paper deals with chain graphs under the classic Lauritzen-Wermuth-Frydenberg interpretation. We prove that the strictly positive discrete probability distributions with the prescribed sample space that factorize according to a chain graph G with dimension d have positive Lebesgue measure wrt R, whereas those that factorize according to G but are not faithful to it have zero Lebesgue measur...

background and aims. one of the most common reasons for the inferior alveolar nerve block anesthesia failure is the variation in mandibular foramen location. the aim of this study was to assess the location of mandibular foramen in children with mandibular retrognathism in comparison to children with normal skeletal occlusion in the mixed dentition. materials and methods. one hundred and twenty...

objectives: proper diagnosis and prevention of malocclusion are superior to treatment. discrepancy between arch length and tooth size in mixed dentition period is a condition requiring timely diagnosis. estimating the mesiodistal width of unerupted teeth according to the size of erupted ones can lead to earlier diagnosis of malocclusion. on the other hand, the best timing for serial extractions...
