text: The state of the art industrial manufacturing process to produce shafts as
counter surfaces for radial shaft seal rings is plunge grinding. This process
consists of three major steps. The blank is turned to a slight diameter-oversize
followed by the heat treatment and the hard-finishing by plunge grinding. The
geometric surface structures of the resulting shafts in general exhibit a stochastic
distribution. These surface characteristics contribute to a reliable and stable
sealing functionality. And the surface and subsurface hardness generally leads
to a higher wear resistance of the shaft. Motivated by economic benefits and in
order to achieve a compact production process for at least ten years, turning
is investigated as an alternative manufacturing process. However due to the resulting
lead structure on the shaft surface and the associated risk of leakage it has
not become prevalent yet. In this paper turned shafts of the metastable austenitic
steel AISI 347 (1.4550, X6CrNiNb1810) are investigated as alternative material
for counter surfaces of radial shaft seal rings and compared to turned shafts
of carburized AISI 5115 (1.7131, 16MnCr5). In addition to surfaces dry turned
at room-temperature, cryogenic turned AISI 347 counter surfaces are analyzed.
By applying cryogenic cooling, the formation of deformation-induced α′-martensite
in the surface layer is possible during the turning process. Endurance tests in
radial shaft seal ring test rigs are performed and complemented with detailed
investigations of microstructure, micro-hardness and surface topography. The results
are compared to results of state of the art ground AISI 5115 shafts.

text: "Schulisches Wohlbe nden ist als Indikator von Schulqualität vor allem für
inklusive Schulen bedeutsam. Als mehrdimensionales Konstrukt wurde es bereits
einschlägig operationalisiert (z. B. Hascher 2004), jedoch nicht in Bezug auf
den Einsatz bei Schülerinnen und Schülern mit sonderpädagogischem Förderbedarf
in inklusiven Schulen der Sekundarstufe I systematisch untersucht. In einem interdisziplinären
Team wurde unter Bezug auf eingeführte Instrumente\r\nein Fragebogen entwickelt
und bei einer Vollerhebung der Jahrgänge 6 bis 10 an der Laborschule Bielefeld,
Versuchsschule des Landes Nordrhein-Westfalen, eingesetzt (N = 292, davon N =
26 mit sonderpädagogischem Förderbedarf). Die beste Modellanpassung im Rahmen
einer kon rmatorischen Faktorenanalyse zur Prüfung der Konstruktvalidität erreicht
ein Modell mit sechs korrelierten Faktoren. Der Beitrag berichtet psychometrische
Kennwerte der Skalen und weitere Ergebnisse, z. B. zur konvergenten Validität."

text: Este artículo concibe la ascendencia como un marcador controvertido de “lo
británico” y de “lo alemán”. Tomando en consideración tanto la evolución de las
leyes de nacionalidad como los datos empíricos del Programa Internacional de Encuestas
Sociales (ISSP, 2003), se demuestra que la distinción “clásica” entre naciones
cívicas y naciones étnicas tiende a sobrestimar las diferencias entre naciones,
mientras que subestima las diferencias intra-nacionales. El hecho de que tanto
en Inglaterra como en Alemania los niveles más altos de educación formal estén
fuertemente asociados a nociones étnicamente más incluyentes de “legítima pertenencia
nacional”, enfatiza el potencial de la educación formal en las sociedades multiculturales
contemporáneas.

text: 'Finding information about people in the World Wide Web is one of the most
common activities of Internet users. It is now impossible to manually analyze
all this information and new approaches are needed that are capable of processing
the large-scale heterogeneous data in order to extract the pertinent information.
The Wikipedia community still puts much effort in manually adding structured data
to biographical articles, the so-called {{Persondata}} template. Thanks to this
kind of metadata, semantically-enriched information concerning the biographee
(e.g. name, date of birth, place of birth) can be extracted and processed by search
engines. But it is a rather time-consuming task and users quite often forget to
add this template: some biographies contain persondata, others do not. There is
considerably less work done on developing approaches to automatically enhance
English Wikipedia biographies with persondata and therefore improve the quality
of structured user contributions. Within this paper, we describe our method to
automatically generate persondata from biographical information in Wikipedia articles.'

text: In this paper, we focus on the acronym representation, the concept of abbreviation
of major terminology. To this end, we try to find the most efficient method to
disambiguate the sense of the acronym. Comparing the various feature types, we
found that using single noun (NN) overwhelmingly outperformed noun phrase (NP)
base. Moreover, the result also showed that collocation information (CL) was not
efficient for enhancing performance considering a huge extra data processing.
We expect to apply the open knowledge base Wikipedia to scholarly service to enhance
the quality of the local knowledge base and to develop value-added services.

text: This paper focuses on the first step in combining prescriptive analytics with
scenario techniques in order to provide strategicdevelopment after the useof InSciTe,
a data prescriptive analytics application. InSciTe supports the improvement of
researchers‘ individual performance by recommending new research directions. Standardized
influential factors are presented as a foundation for automated scenario modelling
such as the prototypical report generation function of InSciTe. Additionally,
a use-case is shown which validatesthe potential of the standardized influential
factors for raw scenario development.

text: 'In this paper, we describe our system developed for the GErman SenTiment
AnaLysis shared Task (GESTALT) for participation in the Maintask 2: Subjective
Phrase and Aspect Extraction from Product Reviews. We present a tool, which identifies
subjective and aspect phrases in German product reviews. For the recognition of
subjective phrases, we pursue a lexicon-based approach. For the extraction of
aspect phrases from the reviews, we consider two possible ways: Besides the subjectivity
and aspect look-up, we also implemented a method to establish which subjective
phrase belongs to which aspect. The system achieves better results for the recognition
of aspect phrases than for the subjective identification.'

text: In this paper, we present a system which makes scientific data available following
the linked open data principle using standards like RDF and URI as well as the
popular D2R server (D2R) and the customizable D2RQ mapping language. Our scientific
data sets include acronym data and expansions, as well as researcher data such
as author name, affiliation, coauthors, and abstracts. The system can easily be
extended to other records. Regarding this, a domain adaptation to patent mining
seems possible. For this reason, obvious similarities and differences are presented
here. The data set is collected from several different providers like publishing
houses and digital libraries, which follow different standards in data format
and structure. Most of them are not supporting semantic web technologies, but
the legacy HTML standard. The integration of these large amounts of scientific
data into the Semantic Web is challenging and it needs flexible data structures
to access this information and interlink them. Based on these data sets, we will
be able to derive a general technology trend as well as the individual research
domain for each researcher. The goal of our Linked Open Data System for scientific
data is to provide access to this data set for other researchers using the Web
of Linked Data. Furthermore we implemented an application for visualization, which
allows usto explorethe relations between single data sets.

text: Joining metals using electrochemical support (ECUF) is a new process for cold
pressure welding sheets and parts. This new process is based on an electrochemical
in-line surface treatment followed by incremental pilger rolling. The ECUF process
intends to cold pressure weld materials under optimized conditions. Oxide layers
on metal surfaces are known to inhibit the formation of cold pressure welds. The
in-line electrochemical treatment will be used to remove these surface oxides
for specific engineering metals and alloys. Hence, an improved pressure weld formation
at lower forces and smaller reduction ratios is expected for the electrochemically
treated surfaces. Using a more flexible pressure welding process, the number of
applications could be greatly improved. First tests with copper were performed
to analyse the efficiency of the proposed electrochemical surface treatments.
Two electrochemical treatments, the cathodic oxide-reduction and cyclovoltammetric
oxide-reduction, were compared with conventional treatments (degreasing and scratch
brushing) regarding their influence on the cold pressure welding process of copper.
The weld strength of lap welds has been investigated as well as the necessary
reduction threshold to form a weld. It was found that the electrochemical oxide
reduction resulted in higher weld strength. The results of scanning electron microscopy
(SEM) and energy dispersive analysis of X-rays (EDX) indicate that surface oxides
were successfully removed by the electrochemical surface treatments. (C) 2014

text: In order to increase mechanical strength, heat dissipation and ampacity and
to decrease failure through fatigue fracture, wedge copper wire bonding is being
introduced as a standard interconnection method for mass production. To achieve
the same process stability when using copper wire instead of aluminum wire a profound
understanding of the bonding process is needed. Due to the higher hardness of
copper compared to aluminum wire it is more difficult to approach the surfaces
of wire and substrate to a level where van der Waals forces are able to arise
between atoms. Also, enough friction energy referred to the total contact area
has to be generated to activate the surfaces. Therefore, a friction model is used
to simulate the joining process. This model calculates the resulting energy of
partial areas in the contact surface and provides information about the adhesion
process of each area. The focus here is on the arising of micro joints in the
contact area depending on the location in the contact and time. To validate the
model, different touchdown forces are used to vary the initial contact areas of
wire and substrate. Additionally, a piezoelectric tri-axial force sensor is built
up to identify the known phases of pre-deforming, cleaning, adhering and diffusing
for the real bonding process to map with the model. Test substrates as DBC and
copper plate are used to show the different formations of a wedge bond connection
due to hardness and reaction propensity. The experiments were done by using 500
$\mu$m copper wire and a standard V-groove tool.

text: Nowadays wire bonding is a widely-used technology for interconnecting chips
in the packaging industry. Thereby, it is known that the bond quality massively
depends upon the microstructure prevailing in the bond and consequently the materials
used as well as the bonding parameters. However the actually used materials such
as aluminum and gold are either characterized by comparibly poor conductivity
or high costs, respectively. Due to its outstanding properties copper is a more
attractive candidate. Still, a thorough investigation on the interrelationship
between the material combinations, the processing parameters and the resulting
microstructure for copper and aluminum wire bonding was not carried out yet. Depending
on the aforementioned factors the microstructural evolution can be completely
different during the bonding process. Therefore, this study focuses on the microstructural
evolution of heavy copper and heavy aluminum wires bonded on copper substrates.
The evolution of the wire microstructure as well as the wire-substrate-interface
was investigated by scanning electron microscope in combination with electron
backscatter diffraction and microhardness measurements. Various samples were extracted
at different points of the bonding process, namely the as-received condition,
after touchdown and after completed bonding. The results of the aluminum and copper
wires were compared to each other in both longitudinal and transversal direction.
It was found, that the two wire materials were completely different in the as-received
condition regarding the grain size, the grain morphology, the texture and the
microhardness. After touchdown the microstructure did not show significant changes
in both materials, yet a strain-hardening was observed in the copper wire resulting
from the touchdown force. When the bonding process was completed a different microstructure
could be observed in both the wire as well as the layer for the materials investigated.
Furthermore, a destinctive increase in the wire hardness could be found in case
of copper, which was not observed for the aluminum wire. The ramifications between
the two wire materials presented in this work will be discussed with the objective
of optimizing the quality of the bonds.

text: (K,Na)NbO3 ceramics have attracted much attention as lead-free piezoelectric
materials with high piezoelectric properties. High-quality (K,Na)NbO3 ceramics
can be sintered using KNbO3 and NaNbO3 powders synthesized by a hydrothermal method.
In this study, to enhance the quality factor of the ceramics, high-power ultrasonic
irradiation was employed during the hydrothermal method, which led to a reduction
in the particle size of the resultant powders.

text: With the paradigm shift towards prognostic and health management (PHM) of
machinery, there is need for reliable PHM methodologies with narrow error bounds
to allow maintenance engineers take decisive maintenance actions based on the
prognostic results. Prognostics is mainly concerned with the estimation of the
remaining useful life (RUL) or time to failure (TTF). The accuracy of PHM methods
is usually a function of the features extracted from the raw data obtained from
sensors. In cases where the extracted features do not display clear degradation
trends, for instance highly loaded bearings, the accuracy of the state of the
art PHM methods is significantly affected. The data which lacks clear degradation
trend is referred to as non-trending data. This study presents a method for extracting
degradation trends from non-trending condition monitoring data for RUL estimation.
The raw signals are first filtered using a discrete wavelet transform (DWT) denoising
filter to remove noise from the acquired signals. Time domain, frequency domain
and time-frequency domain features are then extracted from the filtered signals.
An autoregressive model is then applied to the extracted features to identify
the degradation trends. Features representing the maximum health information are
then selected based on a performance evaluation criteria using extreme learning
machine (ELM) algorithm. The selected features can then be used as inputs in a
prognostic algorithm. The feasibility of the method is demonstrated using experimental
bearing vibration data. The performance of the method is evaluated on the accuracy
of RUL estimation and the results show that the method can be used to accurately
estimate RUL with a maximum error of 10\%.
