text: On-The-Fly (OTF) Computing constitutes an approach towards highly dynamic
and individualized software markets. Based on service-oriented computing, OTF
Computing is about realizing global markets of services that can be flexibly combined.
We report on our current research activities, the security and privacy implications
thereof, and our approaches to tackle the challenges. Furthermore, we discuss
how the security and privacy challenges are addressed in research projects similar
to OTF Computing.

text: Online social networks are attracting billions of nowadays, both on a global
scale as well as in social enterprise networks. Using distributed hash tables
and peer-to-peer technology allows online social networks to be operated securely
and efficiently only by using the resources of the user devices, thus alleviating
censorship or data misuse by a single network operator. In this paper, we address
the challenges that arise in implementing reliably and conveniently to use distributed
data structures, such as lists or sets, in such a distributed hash-tablebased
online social network. We present a secure, distributed list data structure that
manages the list entries in several buckets in the distributed hash table. The
list entries are authenticated, integrity is maintained and access control for
single users and also groups is integrated. The approach for secure distributed
lists is also applied for prefix trees and sets, and implemented and evaluated
in a peer-to-peer framework for social networks. Evaluation shows that the distributed
data structure is convenient and efficient to use and that the requirements on
security hold.

text: We consider the problem of scheduling a number of jobs on $m$ identical processors
sharing a continuously divisible resource. Each job j comes with a resource requirement
r_j \in {0,1}. The job can be processed at full speed if granted its full resource
requirement. If receiving only an x-portion of r_j, it is processed at an x-fraction
of the full speed. Our goal is to find a resource assignment that minimizes the
makespan (i.e., the latest completion time). Variants of such problems, relating
the resource assignment of jobs to their \emph{processing speeds}, have been studied
under the term discrete-continuous scheduling. Known results are either very pessimistic
or heuristic in nature.In this paper, we suggest and analyze a slightly simplified
model. It focuses on the assignment of shared continuous resources to the processors.
The job assignment to processors and the ordering of the jobs have already been
fixed. It is shown that, even for unit size jobs, finding an optimal solution
is NP-hard if the number of processors is part of the input. Positive results
for unit size jobs include an efficient optimal algorithm for 2 processors. Moreover,
we prove that balanced schedules yield a 2-1/m-approximation for a fixed number
of processors. Such schedules are computed by our GreedyBalance algorithm, for
which the bound is tight.

text: When taxes on capital or wealth are levied, in most countries companies have
to be assessed in terms of their market value (MV). Estimating the MV of private
companies for tax purposes is a challenging task for tax authorities as MVs are
not available. In this study, I empirically analyse to what extent an accounting-based
tax valuation method for private companies, a simplified residual income model,
succeeds in matching the MV. I refer to the mandatory Standardised Combination
Model that is a special case of methods commonly used in several countries. In
the absence of market prices for private companies, I use a sample of small German
public companies as a proxy. I validate this approach using a sensitivity analysis
that involves matching the sample of public companies with that of private companies.
The results imply that the mandatory Standardised Combination Model leads to a
severe unequal treatment not only between public and private companies but also
among private companies across and within industries. Furthermore, I simulate
the effects of variation in the key parameters and highlight their impact on the
approximation quality of the Standardised Combination Method. The findings are
relevant to tax reform discussions as well as to tax policy-makers and practitioners
in many countries.

text: 'Max-min fairness (MMF) is a widely known approach to a fair allocation of
bandwidth to each of the users in a network. This allocation can be computed by
uniformly raising the bandwidths of all users without violating capacity constraints.
We consider an extension of these allocations by raising the bandwidth with arbitrary
and not necessarily uniform time-depending velocities (allocation rates). These
allocations are used in a game-theoretic context for routing choices, which we
formalize in progressive filling games (PFGs).We present a variety of results
for equilibria in PFGs. We show that these games possess pure Nash and strong
equilibria. While computation in general is NP-hard, there are polynomial-time
algorithms for prominent classes of Max-Min-Fair Games (MMFG), including the case
when all users have the same source-destination pair. We characterize prices of
anarchy and stability for pure Nash and strong equilibria in PFGs and MMFGs when
players have different or the same source-destination pairs. In addition, we show
that when a designer can adjust allocation rates, it is possible to design games
with optimal strong equilibria. Some initial results on polynomial-time algorithms
in this direction are also derived. '

text: In this work we present the first distributed storage system that is provably
robust against crash failures issued by an adaptive adversary, i.e., for each
batch of requests the adversary can decide based on the entire system state which
servers will be unavailable for that batch of requests. Despite up to \gamma n^{1/\log\log
n} crashed servers, with \gamma>0 constant and n denoting the number of servers,
our system can correctly process any batch of lookup and write requests (with
at most a polylogarithmic number of requests issued at each non-crashed server)
in at most a polylogarithmic number of communication rounds, with at most polylogarithmic
time and work at each server and only a logarithmic storage overhead. Our system
is based on previous work by Eikel and Scheideler (SPAA 2013), who presented IRIS,
a distributed information system that is provably robust against the same kind
of crash failures. However, IRIS is only able to serve lookup requests. Handling
both lookup and write requests has turned out to require major changes in the
design of IRIS.

abstract:
- lang: eng
text: 'In the near future many more compute resources will be available at different
geographical locations. To minimize the response time of requests, application
servers closer to the user can hence be used to shorten network round trip times.
However, this advantage is neutralized if the used data centre is highly loaded
as the processing time of re- quests is important as well. We model the request
response time as the network round trip time plus the processing time at a data
centre.We present a capacitated facility location problem formal- ization where
the processing time is modelled as the sojourn time of a queueing model. We discuss
the Pareto trade-off between the number of used data centres and the resulting
response time. For example, using fewer data centres could cut expenses but results
in high utilization, high response time, and smaller revenues.Previous work presented
a non-linear cost function. We prove its convexity and exploit this property in
two ways: First, we transform the convex model into a linear model while controlling
the maximum approximation error. Sec- ond, we used a convex solver instead of
a slower non-linear solver. Numerical results on network topologies exemplify
our work.'
