text: 'In this paper, we introduce the Woolcano reconfigurable processor architecture.
The architecture is based on the Xilinx Virtex-4 FX FPGA and leverages the Auxiliary
Processing Unit (APU) as well as the partial reconfiguration capabilities to provide
dynamically reconfigurable custom instructions. We also present a hardware tool
flow that automatically translates software functions into custom instructions
and a software tool flow that creates binaries using these instructions. While
previous research on processors with reconfigurable functional units has been
performed predominantly with simulation, the Woolcano architecture allows for
exploring dynamic instruction set extension with commercially available hardware.
Finally, we present a case study demonstrating a custom floating-point instruction
generated with our approach, which achieves a 40x speedup over software-emulated
floating-point operations and a 21% speedup over the Xilinx hardware floating-point
unit. '

text: "We present measurements of the effective electron mass in biaxial tensile
strained silicon on insulator (SSOI) material with 1.2 GPa stress and in unstrained
SOI. Hall-bar metal oxide semiconductor field effect transistors on 60 nm SSOI
and SOI were fabricated and Shubnikov–de Haas oscillations in the temperature
range of T=0.4–4 K for magnetic fields of B=0–10 T were measured. The effective
electron mass in SSOI and SOI samples was determined as mt=(0.20±0.01)m0. This
result is in excellent agreement with first-principles calculations of the\r\neffective
electron mass in the presence of strain."

text: A computational method to obtain optical conductivities from first principles
is presented. It exploits a relation between the conductivity and the complex
dielectric function, which is constructed from the full electronic band structure
within the random-phase approximation. In contrast to the Drude model, no empirical
parameters are used. As interband transitions as well as local-field effects are
properly included, the calculated spectra are valid over a wide frequency range.
As an illustration I present quantitative results for selected simple metals,
noble metals, and ferromagnetic transition metals. The implementation is based
on the full-potential linearized augmented-plane-wave method.

text: We derive formulas for the Coulomb matrix within the full-potential linearized
augmented-plane-wave (FLAPW) method. The Coulomb matrix is a central ingredient
in implementations of many-body perturbation theory, such as the Hartree–Fock
and GW approximations for the electronic self-energy or the random-phase approximation
for the dielectric function. It is represented in the mixed product basis, which
combines numerical muffin-tin functions and interstitial plane waves constructed
from products of FLAPW basis functions. The interstitial plane waves are here
expanded with the Rayleigh formula. The resulting algorithm is very efficient
in terms of both computational cost and accuracy and is superior to an implementation
with the Fourier transform of the step function. In order to allow an analytic
treatment of the divergence at k=0 in reciprocal space, we expand the Coulomb
matrix analytically around this point without resorting to a projection onto plane
waves. Without additional approximations, we then apply a basis transformation
that diagonalizes the Coulomb matrix and confines the divergence to a single eigenvalue.
At the same time, response matrices like the dielectric function separate into
head, wings, and body with the same mathematical properties as in a plane-wave
basis. As an illustration we apply the formulas to electron-energy-loss spectra
(EELS) for nickel at different k vectors including k=0. The convergence of the
spectra towards the result at k=0 is clearly seen. Our all-electron treatment
also allows to include transitions from 3s and 3p core states in the EELS spectrum
that give rise to a shallow peak at high energies and lead to good agreement with
experiment.

text: Schooling and school management can play an important part in promoting inclusive
forms of national attachment, intercultural dialogue and reflexive engagements
with the “Unfamiliar”. The (inter) personal benefits of intercultural experiences
and skills are widely acknowledged. But can we really learn to be intercultural?
And what are the prospects of attachment beyond narrow ethno‐national boundaries
for less privileged members of society? These questions lie at the heart of the
present article. Conceptually, the article draws on Bourdieu's notions of habitus
and cultural capital. Within this framework, I regard people's attachments to
country (and beyond) as learned and habituated, yet open to modification and reconstruction
through reflexive agency, educational practices and the acquisition of intercultural
capital.

text: Ce papier présente le contexte linguistique et la modélisation de notre système
iBeCOOL (Informations Biographiques Extraites à l’aide de COntextes Observés Linguistiquement)
dédié à l’extraction d’informations biographiques dans les textes de la presse
financière en langue anglaise. La notion d’événement biographique (tel que la
naissance, le mariage, la carrière professionnelle) est caractérisée formellement
par un schéma prédicatif à plusieurs arguments dont l’un étant une instance de
la classe d’objets . Notre approche consiste à décrire ces types de
relations à l’aide de grammaires locales etde lexiques terminologiques. Nos résultats
montrent que cette approche semble viable et nous poussent à élargir cette étude
par l’analyse de nouveaux genres textuels.

text: Ultrasonic hyperthermia and thermo-ablation are two promising alternatives
for local overheating of deep-seated human tumours. After a short characterisation
of the two techniques and the identification of the main parameters, results of
an analytical theory of local heat up, cooling, and heat diffusion are presented.
The theory is based on a spherical model for hyperthermia with a critical thermal
dose and on a cylinder-symmetrical model for thermo-ablation with a critical temperature
threshold for thermal toxicity and cell death through coagulative necrosis. Two
representative hard ware concepts are discussed. The hyperthermia applicator consists
of a MHz transducer, which rotates concentrically in a water filled capsule with
acoustically transparent window, and radiates collimated or focussed ultrasound
under 45$\,^{\circ}$ into a concentric target area of nearly spherical symmetry.
The applicator for thermo-ablation is a MHz transducer which radiates high intensity
focussed ultrasound (HIFU) into "cigar shaped" target areas at the focal zone.
Typical therapy diagrams for both techniques are presented. They show therapeutic
target volumes as functions of the therapy time with the peak temperature or the
radiated acoustic power as parameters. These diagrams are discussed under consideration
of power requirement, maximal sound intensity, and power efficiency at close to
optimized frequency conditions.

text: 'Several positioning tasks demand translatory drive instead of rotary motion.
To achieve drives that are capable, e.g., to drive the sunroof of a car or to
lift a car''s window, multiple miniaturized motors can be combined. But in this
case many other questions arise: The electromechanical behavior of the individual
motors differs slightly, the motor characteristics are strongly dependent on the
driving parameters and the driven load, many applications need some extra power
for special cases like overcoming higher forces periodically. Thus, the bundle
of motors has to act well-organized and at last controlled to get an optimized
drive that is not oversized and costly.'

text: For devices having non-linear contact, load plays a fundamental role. Variations
in the characteristics of the load cause change in eigenfrequency and amplitude
of the vibration. In most technical applications, this unwanted behaviour is cancelled
by the use of control algorithms. However, multiple applications, like bond quality
monitoring or chemical and pressure sensors, have found that the load may be characterised
by interpreting the change in characteristics of a resonant vibrating device used
as a sensor. Surgical resection of tumours is a very difficult task. After localising
the tumour by the use of imaging techniques, the resection demands the surgeon
to decide where and what to resect based on visual and tactile differentiation
of tumour and healthy tissue. Exactness of this process could be enhanced if we
can provide the surgeon with a device capable of evaluating mechanical characteristics
of the tissue much more accurately than the surgeon himself can do. As the mechanical
characteristics of tumour and healthy tissue differ but slightly, the task is
to design a system with high sensitivity. Therefore, we have developed a resonant
actuator-sensor that allows the differentiation among distinct media that have
similar mechanical characteristics to tumour and healthy tissue using a piezoelectric
bimorph. The design is based on the detection and evaluation of frequency shift
and amplitude variation of the fundamental and higher harmonics using one layer
for the resonant excitation of vibration and the other one as the sensing element.

text: Many ultrasonic processes are based on the mechanical contact of oscillating
parts. Within ultrasonic machining (drilling, milling, grinding) micro impacts
lead to abrasion at the processed workpiece and hopefully do not damage the tool.
In ultrasonic motors ideally neither part gets worn. Thus the appropriate design
of contact partners as well as their kinematics is a substantial task during the
development of such devices. A first step to optimize contact mechanics is to
understand their behavior and dependencies on parameter variations, such as vibration
amplitude and pre-stress of the impacting parts. For a detailed understanding
models validated with convincing experimental data from measurements are absolutely
essential. This paper focuses on simple vibro-impact experiments which can be
used as benchmark data for future models. The setup of the experiment and first
experimental investigations are described in detail.

text: The standard approach of job search engines disregards the structural aspect
of job announcements in the Web. Bag-of-words indexing leads to a high amount
of noise. In this paper we describe a method that uses local grammars to transform
unstructured Web pages into structured forms. Evaluation experiments show high
efficiency of information access to the generated documents.
