Comparison of Scatter Correction Methods for CBCT

Roland E. Suri, Gary Virshup, Wolfgang Kaissl & Luis Zurkirchen
In contrast to the narrow fan of clinical Computed Tomography (CT) scanners, Cone Beam scanners irradiate a much larger proportion of the object, which causes several times more X-rays scattering. If this scatter is not corrected, the reconstructed images exhibit artifacts: The middle area of the object becomes darker than the outer area, as the density in the middle of the object is underestimated. We compared three methods of correcting for scatter artifacts. 1) A...

E-Cast: Elastic Multicast

Philipp Unterbrunner, Gustavo Alonso & Donald Kossmann
This technical report describes E-Cast: a uniform causal-total-order multicast protocol designed to implement fault tolerant, highly elastic, yet strongly consistent database engines in the cloud. In contrast to traditional group communication, the model underlying E-Cast defines multicast as a stateful routing problem. In this document, we provide a rigorous formalization of the routing problem, show how partial replication with strong consistency guarantees can be reduced to said routing problem, and present its efficient algorithmic solution,...

Building Data Flows Using Distributed Key-Value Stores

Martin Hentschel, Maxim Grinev & Donald Kossmann
Social communication features on most of today’s largest websites require propagating the data inside the database/key-value store leading to massive data flows. In this paper we study alternative architectures to build data flows using distributed key-value stores. We compare programming model, execution model, failure model, and scalability highlighting a problem of the state-of-the-art architecture based on an external queue: non-optimal resource utilization. As part of this study, we propose an optimization of this approach by...

Rules vs. targets: Climate treaties under uncertainty

Hans Gersbach & Quirin Oberpriller
We demonstrate the advantages of a climate treaty based solely on rules for international permit markets when there is uncertainty about abatement costs and environmental damages. Such a ‘Rules Treaty’ comprises a scaling factor and a refunding rule. Each signatory can freely choose the number of permits it allocates to domestic firms. For every permit so issued, an international agency is allowed to issue additional permits in accordance with the scaling factor. The agency auctions...

Activity identification and primary location modelling based on smart card payment data for public transport

Artem Chakirov & Alexander Erath
The introduction of electronic payment systems for public transport in many cities all over the world enabled collection of detailed and comprehensive data records of public transport journeys. Processing and mining of these data opens new opportunities in transport modelling and travel behaviour research. In particular its potential for identification and analysis of activities, which cause regular travels, represents a highly interesting research question. In this paper, opportunities for detection of primary activities, as home...
