text: The link between formal education and national identities is widely acknowledged.
Empirical research on national and supranational identities of teachers, however,
is still relatively rare. Whilst a number of studies consider the special population
of teachers, these contributions do not consistently focus on national and supranational
identities. Based on a case study of 72 trainee teachers from Baden‐Württemberg
(Germany), the present paper looks at the reconcilability of national and European
identities and explores notions of the European Union in terms of cultural and
geographical inclusiveness. Findings on the case study level are considered in
their own right, but also compared to findings on the regional, national and European
level, using relevant Eurobarometer survey data. The article shows that high levels
of attachment to nation and high levels of attachment to Europe do not have to
be mutually exclusive. It also demonstrates that, for most trainee teachers, the
European Union constitutes a culturally and geographically inclusive institution
that is supposed to stand for cultural diversity, peace, freedom and respect of
human rights. Through comparisons that go beyond the case study level, the paper
recognises the importance of regional and national contexts. Nonetheless, it argues
that some of its findings are likely to be relevant for studies of national and
European identities across different European societies.

text: 'The design of piezoelectric transducers is usually based on single-objective
optimization only. In most practical applications of piezoelectric transducers,
however, there exist multiple design objectives that often are contradictory to
each other by their very nature. It is impossible to find a solution at which
each objective function gets its optimal value simultaneously. Our design approach
is to first find a set of Pareto-optimal solutions, which can be considered to
be best compromises among multiple design objectives. Among these Pareto-optimal
solutions, the designer can then select the one solution which he considers to
be the best one. In this paper we investigate the optimal design of a Langevin
transducer. The design problem is formulated mathematically as a constrained multiobjective
optimization problem. The maximum vibration amplitude and the minimum electrical
input power are considered as optimization objectives. Design variables involve
continuous variables (dimensions of the transducer) and discrete variables (the
number of piezoelectric rings and material types). In order to formulate the optimization
problem, the behavior of piezoelectric transducers is modeled using the transfer
matrix method based on analytical models. Multiobjective evolutionary algorithms
are applied in the optimization process and a set of Pareto-optimal designs is
calculated. The optimized results are analyzed and the preferred design is determined. '

text: 'Classically, rotary motors with gears and spindle mechanisms are used to
achieve translatory motion. In means of miniaturization and weight reduction piezoelectric
linear motors are of interest. Several ultrasonic linear motors found in literature
base on the use of two different vibration modes. Most often flexural and longitudinal
modes are combined to achieve an elliptic micro-motion of surface points. This
micro-motion is converted to direct linear (or translatory) motion of a driven
slider. To gain high amplitudes of the micro-motion and thus having a powerful
motor, the ultrasonic vibrator should be driven near the eigenfrequency of its
modes. Additionally, low mechanical and electrical losses lead to increased efficiency
and large amplitude magnification in resonance. This demands a geometrical design
that fits the eigenfrequencies of the two different modes. A frequency-deviation
of only a few percent leads to non-acceptable disturbance of the elliptical motion.
Thus, the mechanical design of the vibrators has to be done very carefully. Within
this contribution we discuss different motor designs based on the coupling of
two the same longitudinal vibrations within one structure to generate an elliptic
motion of surface points. Different concepts based on piezoelectric plates and
Langevin transducers are compared. Benefits and drawbacks against the combination
of longitudinal and bending modes will be discussed. Numerical results of the
stator vibration as well as motor characteristics are validated by measurements
on different prototypes. '

text: Piezoelectric transformers are increasingly getting popular in the electrical
devices owing to several advantages such as small size, high efficiency, no electromagnetic
noise and non-flammable. In addition to the conventional applications such as
ballast for back light inverter in notebook computers, camera flash, and fuel
ignition several new applications have emerged such as AC/DC converter, battery
charger and automobile lighting. These new applications demand high power density
and wide range of voltage gain. Currently, the transformer power density is limited
to $40 W/cm{^3}$ obtained at low voltage gain. The purpose of this study was to
investigate a transformer design that has the potential of providing higher power
density and wider range of voltage gain. The new transformer design utilizes radial
mode both at the input and output port and has the unidirectional polarization
in the ceramics. This design was found to provide 30 W power with an efficiency
of 98\% and 30 $\,^{\circ}$C temperature rise from the room temperature. An electro-mechanical
equivalent circuit model was developed to describe the characteristics of the
piezoelectric transformer. The model was found to successfully predict the characteristics
of the transformer. Excellent matching was found between the computed and experimental
results. The results of this study will allow to deterministically design unipoled
piezoelectric transformers with specified performance. It is expected that in
near future the unipoled transformer will gain significant importance in various
electrical components.

text: An improved concept for ultrasonic hyperthermia of tumors is presented. This
concept is based on past experience of a German government supported project [1],
which ended in 1984. It offers a low cost alternative to common RF- and microwave
methods for hyperthermia of tumors with volumes between 1 and 40 ml at treatment
times between 30 and 60 min. Our new version of the system considerably improves
the temperature suppression in the healthy tissue around the target area and enables
the adjustment of the beam width to the actual tumor size and the field geometry
to the depth and shape of the tumor. The applicator can be used for moderate hyperthermia
with tissue overheating up to 10 K or for ablation therapy with short high temperature
pulses. Its central area is free for the integration of a commercial ultrasonic
diagnostic sector scanner or a Doppler flow sensor in order to support the adjustment
of the transducer and to monitor the whole area during the therapy.

text: Rotary ultrasonic motors have found broad industrial application in camera
lens drives and other systems. Linear ultrasonic motors in contrast have only
found limited applications. The main reason for the limited range of application
of these very attractive devices seems to be their small force and power range.
Attempts to build linear ultrasonic motors for high forces and high power applications
have not been truly successful yet. To achieve larger force and higher power,
multiple miniaturized motors can be combined. This approach, however, is not as
simple as it appears at first glance. The electromechanical behaviour of the individual
motors differs slightly due to manufacturing and assembly tolerances. The individual
motor characteristics are strongly dependent on the driving parameters (frequency,
voltage, temperature, pre-stress, etc.) and the driven load and the collective
behaviour of the swarm of motors is not just the linear superposition of the individual
drive's forces. Thus, the bundle of motors has to be synchronized and controlled
appropriately in order to obtain an optimized drive that is not oversized and
costly. We have investigated driving and control strategies of a set of linear
ultrasonic motors. Our contribution will be divided into three main parts. In
part I ultrasonic linear motors will be introduced. In part II driving strategies
for a single motor as well as for a bundle of motors will be presented. These
concepts will be verified by simulation results and experimental data. In part
III a simplified model for the motor's electromechanical behaviour will be given.

text: This paper presents a general model based on the electromechanical circuit
theory. The model is set up as a mechanical equivalent model for base excited
systems and describes the behaviour of a piezoelectric element around one resonance
frequency which is sufficient for most practical applications. The model is extended
to obtain the influence of geometrical and material properties. The derivated
properties are used to describe the parameters of the general model which is easy
to handle. Using this model either the calculation of the output power on a specific
electric load or the determination of the design of the used piezoelectric element
for a needed electric output power is possible. The paper focuses on the design
of the ratio of length and width of a piezoelectric bimorph. The validity of the
model is shown by the comparison of computed and experimental results.

text: We propose a new method for calculating optical defect levels and thermodynamic
charge-transition levels of point defects in semiconductors, which includes quasiparticle
corrections to the Kohn-Sham eigenvalues of density-functional theory. Its applicability
is demonstrated for anion vacancies at the (110) surfaces of III–V semiconductors.
We find the (+/0) charge-transition level to be 0.49 eV above the surface valence-band
maximum for GaAs(110) and 0.82 eV for InP(110). The results show a clear improvement
over the local-density approximation and agree closely with an experimental analysis.

text: This paper investigates the influence of the basis set on the GW self-energy
correction in the full-potential linearized augmented-plane-wave (LAPW) approach
and similar linearized all-electron methods. A systematic improvement is achieved
by including local orbitals that are defined as second and higher energy derivatives
of solutions to the radial scalar-relativistic Dirac equation and thus constitute
a natural extension of the LAPW basis set. Within this approach linearization
errors can be eliminated, and the basis set becomes complete. While the exchange
contribution to the self-energy is little affected by the increased basis-set
flexibility, the correlation contribution benefits from the better description
of the unoccupied states, as do the quasiparticle energies. The resulting band
gaps remain relatively unaffected, however; for Si we find an increase of 0.03
eV.
