Zusammenfassung: In den letzten Jahren wird vielfach in Wissenschaft und Praxis unter dem Begriff des Customer Relationship Management (CRM) eine nachhaltig kundenorientierte Ausrichtung von Unternehmen diskutiert. Allerdings scheitern, nach anfänglich großen Erwartungen, zahlreiche CRM-Projekte. Eine überschätzte bzw. schlechte Datenqualität ist dabei sehr häufig als einer der Gründe angeführt...

Most current flow routing algorithms use digital elevation models (DEMs) to construct flow models. In order to successfully use current techniques for flow routing, they flood local minima and then find a way of routing the flow across the flat surfaces. In this paper, we examine an alternative method for computing flow routing on these flooded surfaces that takes into account the original elev...

Geologic variation has important influences on habitat quality for species of concern, but it can be difficult to evaluate due to subtle variations, complex terminology, and inadequate maps. To better understand habitat of the Apache trout (Onchorhynchus apache or O. gilae apache Miller), a threatened endemic species of the White Mountains of eastcentral Arizona, we reviewed existing geologic r...

Zusammenfassung Herzchirurgische Operationen sind mit dem Risiko verbunden, einen relevanten Blutverlust zu erleiden und eine Transfusion von Blutprodukten zu erhalten. Neben dem Blutverlust treten internationalen Studien zufolge schwere Blutungen, die eine Reoperation zur Blutstillung erfordern, bei 3-5% der Patienten auf. Die Morbidität und Mortalität ist signifikant erhöht, so dass eine effe...

In this paper, we present an automatic building extraction method based on an object approach from Digital Elevation Models. First, a rough approximation of the building footprints is realized by a method based on marked point processes: the building footprints are modeled by rectangle layouts. Then, these rectangular footprints are regularized by improving the connection between the neighborin...

It's not surprisingly when entering this site to get the book. One of the popular books now is the digital terrain modeling principles and methodology. You may be confused because you can't find the book in the book store around your city. Commonly, the popular book will be sold quickly. And when you have found the store to buy the book, it will be so hurt when you run out of it. This is why, s...

Three-dimensional mapping products in the form of DEMs (Digital Elevation Models) have become much more accessible in recent years, in part due to the implementation of LIDAR and IFSAR technologies. While there is considerable familiarity with one technology or the other, they are not often examined in terms of their mutually similar characteristics or equally those that are dissimilar. The pur...

background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

Multiresolution models are getting more and more importance for a scale-sensitive modelling of spatial data. In principle, they allow the representation of the data at a variety of scales. Of special importance are adaptive methods, where the resolution does not need to be uniform but may be variable. Then, error indicators are used to control the local resolution of the model. In this paper, w...

BACKGROUND There are poorer outcomes following ST elevation myocardial infarction in blacks compared to white patients despite comparable door-to-reperfusion time. We hypothesized that delays to hospital presentation may be contributory. METHODS AND RESULTS We conducted a retrospective analysis of the 1144 patients admitted for STEMI in our institution from 2008 to 2013. The door-to-balloon t...
