text: 'In the context of photoelectron spectroscopy, the GW approach has developed
into the method of choice for computing excitation spectra of weakly correlated
bulk systems and their surfaces. To employ the established computational schemes
that have been developed for three-dimensional crystals, two-dimensional systems
are typically treated in the repeated-slab approach. In this work we critically
examine this approach and identify three important aspects for which the treatment
of long-range screening in two dimensions differs from the bulk: (1) anisotropy
of the macroscopic screening, (2) k-point sampling parallel to the surface, (3)
periodic repetition and slab-slab interaction. For prototypical semiconductor
(silicon) and ionic (NaCl) thin films we quantify the individual contributions
of points (1) to (3) and develop robust and efficient correction schemes derived
from the classic theory of dielectric screening.'

text: "Dieses Buch beschäftigt sich mit Algorithmen und Methoden der Peer-to-Peer-Netzwerke
und gibt einen Einblick in die aktuelle Forschung.\r\n\r\nUrsprünglich waren Peer-to-Peer-Netzwerke
nur für File-Sharing konzipiert. Mittlerweile hat sich Peer-to-Peer zum Paradigma
für Rechnernetzwerke entwickelt. Ziel dieses Buches ist es, dem Leser ein grundlegendes
Verständnis der Techniken hinter den aktuellen Peer-to-Peer-Netzwerken aufzuzeigen
und im nächsten Schritt Algorithmen vorzustellen, die vielleicht erst in einigen
Jahren umgesetzt werden.\r\n\r\nDas Buch richtet sich in erster Linie an Informatiker
(Studenten ab dem 5. Semester). Aber auch interessierte Nichtinformatiker können
von diesem Buch profitieren, wobei grundlegende Kenntnisse aus den Bereichen der
Mathematik und Informatik vorausgesetzt werden. Die Ziele, Kernaussagen und Ergebnisse
sollten jedoch auch ohne akademischen Hintergrund klar werden."

text: 'Current research in Micro, Nano and Swarm Robots as results of the European
projects Miniman, MiCRoN and I-SWARM will be presented. First, the design and
the control of 5 to 10cm3 sized mobile micro robots with five degrees of freedom
will be shown. They can handle miniaturized parts as for example an optical component
or a biological cell with a size in the micrometre-area with an accuracy of 100nm
under a microscope or a raster-electron microscope. Second, the design and the
control of a 1cm3-sized mobile untethered micro robot will be demonstrated. Here,
the robot consists of five parts: the Piezzo locomotion module, the micro control
unit, the communication unit, the navigation system and the micro gripper. The
mobile robot can be guided and positioned in an arena with an accuracy of 5 micrometre
and can be programmed and controlled over the wireless communication unit. Third,
the design and the control of 3 × 3 × 3 mm3 sized micro-/nanorobots with 2 degrees
of freedom will be presented. The transmission of energy and the communication
between the robots is realized via infrared. The robot controller is fully integrated
and has limited functionalities. Via basic sensors communication functions and
elementary rules and behaviours the micro robot can act in a swarm consisting
of hundreds and thousands of robots. Future applications could be monitoring-,
inspection-, exploring-tasks etc. of big areas or objects.'

text: We present a quantitative parameter-free method for calculating defect states
and charge-transition levels of point defects in semiconductors. It combines the
strength of density-functional theory for ground-state total energies with quasiparticle
corrections to the excitation spectrum obtained from many-body perturbation theory.
The latter is implemented within the G0W0 approximation, in which the electronic
self-energy is constructed non-self-consistently from the Green’s function of
the underlying Kohn–Sham system. The method is general and applicable to arbitrary
bulk or surface defects. As an example we consider anion vacancies at the (110)
surfaces of III–V semiconductors. Relative to the Kohn–Sham eigenvalues in the
local-density approximation, the quasiparticle corrections open the fundamental
band gap and raise the position of defect states inside the gap. As a consequence,
the charge-transition levels are also pushed to higher energies, leading to close
agreement with the available experimental data.

text: In the StrSort model [2], the input is given as a stream, e.g. a sequence
of points, and an algorithm can perform (a) streaming and (b) sorting passes to
process the stream. A streaming pass reads the input stream from left to right
and writes an output stream, which is the input of the next pass. A sorting pass
is a black box operation that sorts a stream according to some partial order.
In this paper, we develop algorithms for two basic geometric problems in the StrSort
model. At first, we propose a divide-and-conquer algorithm that computes the convex
hull of a point set in 2D in O(log2 n) passes using O(1) memory. Then we give
a StrSort algorithm to compute a (1+ε)-spanner for a point set in Rd for constant
d and constant epsilon that uses O(logd-1 n) passes and O(log n) space. This result
implies a (1+ε)-approximation of the Euclidean minimum spanning tree in Rd, for
constant d and ε.

text: Penetration tests (Magness-Taylor, force/deformation, Kramer multiblade shear)
applied directly over the peel of the fruit are the most acceptable methods for
measuring firmness and turgidity of fruits and vegetables [1, 2]. To replace these
destructive and mechanical penetration methods by non-destructive ultrasonic measurements
implies a great advance in order to obtain fast studies about the state of the
fruit at the time of harvest, during storage, and in the distribution points.
Moreover, there are other advantages since this technique can be fast, non-destructive,
fully automated, and performed on-line [1]. Within this context, the objective
of this study was to examine the relationship between physico-mechanical characteristics
(oil-gland break stress, thickness and dehydration) and ultrasonic characteristics
in the ``Salustiana'' orange peel during the complete dehydration process of the
orange at ambient conditions. After a description of the measurement system [3],
the fruit selection procedure and the measurement protocol, we analyze the results
of the change of physico-mechanical and ultrasonic properties in the orange peel
and their change with storage time.

text: 'Email communication is encumbered with a mass of email messages which their
recipients have neither requested nor require. Even worse, the impacts of these
messages are far from being simply an annoyance, as they also involve economic
damage. This manuscript examines the resource ?email addresses?, which is vital
for any potential bulk mailer and spammer. Both a methodology and a honeypot conceptualization
for implementing an empirical analysis of the usage of email addresses placed
on the Internet are proposed here. Their objective is to assess, on a quantitative
basis, the extent of the current harassment and its development over time. This
?framework? is intended to be extensible to measuring the effectiveness of address-obscuring
techniques. The implementation of a pilot honeypot is described, which led to
key findings, some of them being: (1) Web placements attract more than two-thirds
(70\%) of all honeypot spam emails, followed by newsgroup placements (28.6\%)
and newsletter subscriptions (1.4\%), (2) the proportions of spam relating to
the email addresses? top-level domain can be statistically assumed to be uniformly
distributed, (3) More than 43\% of addresses on the web have been abused, whereas
about 27\% was the case for addresses on newsgroups and only about 4\% was the
case for addresses used for a newsletter subscription, (4) Regarding the development
of email addresses? attractiveness for spammers over time, the service ?web sites?
features a negative linear relationship, whereas the service ?Usenet? hows a negative
exponential relationship. (5) Only 1.54\% of the spam emails showed an interrelation
between the topic of the spam email and that of the location where the recipient?s
address was placed, so that spammers are assumed to send their emails in a ?context
insensitive? manner. The results of the empirical analysis motivate the need for
the protection of email addresses through obscuration. We analyze this need by
formulating requirements for address obscuring techniques and we reveal to which
extent today?s most relevant approaches fulfill these requirements.'

text: 'Continuous and reliable concentration measurement of liquids still is a great
challenge as the sensor systems have to meet high industrial requirements. Apart
from chemical sensors there are a couple of acoustic systems [1] that are well
suited for a lot of industrial applications. Most of them determine the amplitude
ratio of deflected ultrasound bursts at different boundaries as well as the sound
velocity of the liquid in order to calculate its acoustic impedance and therewith
its density. The advantages of acoustic sensors are their robustness and their
fast response. Their disadvantages are sensitivity against variations of the reference
material properties as well as abrasion or soiling of the boundaries. This contribution
is about a new model-based method that uses the whole surface of an acoustic waveguide
as reference boundary: It has turned out that the principal components of a signal
at the end of the waveguide can be assigned to the different propagative acoustic
modes (Fig. 1). Therefore it is necessary to use different simulation tools, e.g.
FEM and modal analysis (Fig. 2). With this it is possible to determine the amplitudes
of each mode by means of one measured signal at the end of the waveguide and Gauss
Algorithm even if the transducer is of very simple kind [2]. Therewith it is possible
to get redundant information -- one amplitude for each mode -- for the liquid
impedance. In addition to that it is possible to generate an acoustic reference
signal without information about the liquid impedance but dissipation if we use
the fundamental mode. The different signal amplitudes and a model of acoustic
wave propagation [2, 3] offer the possibility to distinguish between dissipation
in the liquid and attenuation due to the impedance relations. Moreover, if there
are enough analysable amplitudes available, variations of the reference material
properties can be determined.'

text: In many applications ultrasonic transducers are used for transmitting and
receiving ultrasonic waves. Ultrasonic sensor systems meet the practical requirements
of industrial applications quite well. Typical sensor applications are for example
the measurement of distance and thickness. Especially if only one ultrasonic transceiver
and the well-known pulse-echo-method are used, the sensor electronics has to switch
from transmitting to receiving mode. This is one of the most limiting properties
because the probe can not receive echoes from nearby obstacles or thin material
layers. This contribution deals with the development of an electronic interface
circuit for ultrasonic sensors allowing transmitting and receiving of acoustic
signals simultaneously. There are already several methods to separate the transmitted
from the received signal for instance the well-known circulator in the telephone,
the differential transformer mentioned by Bradfield [1] or a directional coupler
[2]. The directional coupler consists of two broadband transformers linked with
each other in such a way that it equally distributes the input power at port one
to the third and fourth port, while port two is isolated. This circuit is also
known as 3 dB directional coupler and makes it possible to get reference echoes
directly from the interface between the sensor and the medium of interest. Several
reflectors or multiple sound paths such as used in ultrasonic density measurement
systems are unnecessary [3].
