text: In this paper we present a system for indoor navigation based on received
signal strength index information of Wireless-LAN access points and relative position
estimates. The relative position information is gathered from inertial smartphone
sensors using a step detection and an orientation estimate. Our map data is hosted
on a server employing a map renderer and a SQL database. The database includes
a complete multilevel office building, within which the user can navigate. During
navigation, the client retrieves the position estimate from the server, together
with the corresponding map tiles to visualize the user's position on the smartphone
display.

text: To optimize the ultrasound irradiation for cavitation based ultrasound applications
like sonochemistry or ultrasound cleaning, the correlation between cavitation
intensity and the resulting effect on the process is of interest. Furthermore,
changing conditions like temperature and pressure result in varying acoustic properties
of the liquid. That might necessitate an adaption of the ultrasound irradiation.
To detect such changes during operation, process monitoring is desired. Labor
intensive processes, that might be carried out for several hours, also require
process monitoring to increase their reliability by detection of changes or malfunctions
during operation. In some applications cavitation detection and monitoring can
be achieved by the application of sensors in the sound field. Though the application
of sensors is possible, this necessitates modifications on the system and the
sensor might disturb the sound field. In other applications harsh, process conditions
prohibit the application of sensors in the sound field. Therefore alternative
techniques for cavitation detection and monitoring are desired. The applicability
of an external microphone and a self-sensing ultrasound transducer for cavitation
detection were experimentally investigated. Both methods were found to be suitable
and easily applicable.

text: 'The rapid development of communication and information technology opens up
fascinating perspectives, which go far beyond the state of the art in mechatronics:
mechatronic systems with inherent partial intelligence. These so called self-optimizing
systems adapt their objectives and behavior autonomously and flexibly to changing
operating conditions. On the one hand, securing the dependability of such systems
is challenging due to their complexity and non-deterministic behavior. On the
other hand, self-optimization can be used to increase the dependability of the
system during its operation. However, it has to be ensured, that the self-optimization
works dependable itself. To cope with these challenges, the multi-level dependability
concept was developed. It enables predictive condition monitoring, influences
the objectives of the system and determines suitable means to improve the system''s
dependability during its operation. In this contribution we introduce a procedure
for the conceptual design of an advanced condition monitoring based on the system''s
principle solution. The principle solution describes the principal operation mode
of the system and its desired behavior. It is modeled using the specification
technique for the domain-spanning description of the principle solution of a self-optimizing
system and consists of a coherent system of eight partial models (e.g. requirements,
active structure, system of objectives, behavior, etc.). The partial models are
analyzed separately in order to derive the components of the multi-level dependability
concept. In particular, the reliability analysis of the partial model active structure
is performed to identify the system elements to be monitored and parameters to
be measured. The principle solution is extended accordingly: e.g. with system
elements required for the realization of the dependability concept. The advantages
of the method are shown on the self-optimizing guidance module of a railroad vehicle.'

text: This paper proposes a quality driven, simulation based approach to functional
design verification, which applies mainly to IP-level HDL designs with well specified
test instruction format and is evaluated on a soft microprocessor core MB-LITE
[5]. The approach utilizes mutation analysis as the quality metric to steer an
automated simulation data generation process. It leads to a simulation flow with
two phases towards an enhanced mutation analysis result. First in a random simulation
phase, an in-loop heuristics is deployed and adjusts dynamically the test probability
distribution so as to improve the coverage efficiency. Next, for each remaining
hard-to-kill mutant, a search heuristics on test input space is developed to iteratively
locate a target test, using a specific objective cost function for the goal of
killing HDL mutant. The effectiveness of this integrated two-phase simulation
flow is demonstrated by the results with the MB-LITE microprocessor IP.

text: The paper proposes a modification of the standard maximum a posteriori (MAP)
method for the estimation of the parameters of a Gaussian process for cases where
the process is superposed by additive Gaussian observation errors of known variance.
Simulations on artificially generated data demonstrate the superiority of the
proposed method. While reducing to the ordinary MAP approach in the absence of
observation noise, the improvement becomes the more pronounced the larger the
variance of the observation noise. The method is further extended to track the
parameters in case of non-stationary Gaussian processes.

text: In this paper, we present a novel blocking matrix and fixed beamformer design
for a generalized sidelobe canceler for speech enhancement in a reverberant enclosure.
They are based on a new method for estimating the acoustical transfer function
ratios in the presence of stationary noise. The estimation method relies on solving
a generalized eigenvalue problem in each frequency bin. An adaptive eigenvector
tracking utilizing the power iteration method is employed and shown to achieve
a high convergence speed. Simulation results demonstrate that the proposed beamformer
leads to better noise and interference reduction and reduced speech distortions
compared to other blocking matrix designs from the literature.

text: HDL-mutation based fault injection and analysis is considered as an important
coverage metric for measuring the quality of design simulation processes [20,
3, 1, 2]. In this work, we try to solve the problem of automatic simulation data
generation targeting HDL mutation faults. We follow a search based approach and
eliminate the need for symbolic execution and mathematical constraint solving
from existing work. An objective cost function is defined on the test input space
and serves the guidance of search for fault-detecting test data. This is done
by first mapping the simulation traces under a test onto a control and data flow
graph structure which is extracted from the design. Then the progress of fault
detection can be measured quantitatively on this graph to be the cost value. By
minimizing this cost we approach the target test data. The effectiveness of the
cost function is investigated under an example neighborhood search scheme. Case
study with a floating point arithmetic IP design has shown that the cost function
is able to guide effectively the search procedure towards a fault-detecting test.
The cost calculation time as the search overhead was also observed to be minor
compared to the actual design simulation time.

text: In a world, where more and more businesses seem to trade in an online market,
the supply of online services to supply the ever-growing demand could quickly
reach its capacity limits. Online service providers may find themselves maxed
out at peak operation levels during high-traffic timeslots but too little demand
during low-traffic timeslots, although the latter is becoming less frequent. At
this point not only deciding which user is allocated what level of service becomes
essential, but also the magnitude of the service provided, can be controlled by
pricing. Pricing is an important factor when efficient and acceptable allocation
of resources between individuals must be reached. Without prices, transferring
or sharing goods would be impossible. In sharing information, pricing a product
however is not as simple as relatively pricing an apple or a pear. Often the costs,
and hence the prices are simply unknown. Backed by this scenario, the online services
market could be combined with the market design mechanism of diamonds. For this
we propose an ultimatum pricing strategy which effectively allows for valuations
to be accounted for, but no longer a necessity when pricing in grid, cloud or
other online computing environments.

text: Self-optimizing systems are able to adapt their behavior autonomously according
to their current self-determined objectives. Unforeseen influences could lead
to dependability-critical behavior of the system. Methods are required which secure
self-optimizing systems during operation. These methods to increase the dependability
of the system should already be taken into consideration in the design process.
This paper presents a guideline for the dependability-oriented design of self-optimizing
systems, which integrates established classical methods like failure mode and
effects analysis as well as methods based on self-optimization. On the one hand
self-optimization is used to increase the dependability of the system by integrating
objectives like safety, availability, and reliability to the objectives of the
system. On the other hand methods are required to ensure the self-optimization
itself. As basis for this guideline serves the principle solution of the system.
The six phases of the guideline extend the design process and lead to an enhanced
principle solution. Additionally, the guideline illustrates phases to implement
and validate the self-optimizing system. The proposed guideline is applied to
an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
function modules.

text: In this paper, we present a new technique for automatic speech recognition
(ASR) in reverberant environments. Our approach is aimed at the enhancement of
the logarithmic Mel power spectrum, which is computed at an intermediate stage
to obtain the widely used Mel frequency cepstral coefficients (MFCCs). Given the
reverberant logarithmic Mel power spectral coefficients (LMPSCs), a minimum mean
square error estimate of the clean LMPSCs is computed by carrying out Bayesian
inference. We employ switching linear dynamical models as an a priori model for
the dynamics of the clean LMPSCs. Further, we derive a stochastic observation
model which relates the clean to the reverberant LMPSCs through a simplified model
of the room impulse response (RIR). This model requires only two parameters, namely
RIR energy and reverberation time, which can be estimated from the captured microphone
signal. The performance of the proposed enhancement technique is studied on the
AURORA5 database and compared to that of constrained maximum-likelihood linear
regression (CMLLR). It is shown by experimental results that our approach significantly
outperforms CMLLR and that up to 80\% of the errors caused by the reverberation
are recovered. In addition to the fact that the approach is compatible with the
standard MFCC feature vectors, it leaves the ASR back-end unchanged. It is of
moderate computational complexity and suitable for real time applications.

as a cognitive and communicative activity. What has to be taken into account when
developing a methodology for writing research from a cultural-historical and dialogical
perspective? Firstly, writing is not separated from other forms of speech activity
like interpersonal and intrapersonal speech. Thus, inner dialogue and the addressed
character of writing become crucial notions to be methodologically considered.
Secondly, contrary to current writing research traditions such as literacy studies
and studies of the writing process in cognitive psychology, both individual writing
processes and socio-cultural writing practices as well as their relationship must
be considered. These reflections lead towards the conclusion that writing is not
fully accessible to external observation or to introspection. In consequence,
a suggestion of a methodological approach is given, inspired by the activity theoretically
informed method of auto-confrontation. The proposed method consists of two phases:
a) videotaping of a writing episode and b) co-analysis of the videotaped writing
episode in dialogue between writer and researcher. The second phase transfers
the writing activity into a new context where understanding it becomes possible.
The co-analysis makes involved positions audible: positions of the writer and
of the researcher, of real and imagined readers as well as intersubjective and
community-related positions. Finally, implications of the proposed research setting
are discussed and evaluated with regard to the theoretical grounding. An instance
of the methodology to be sketched in this article was developed in the context
of the author’s dissertation project in preparation at Ludwig-Maximilians-Universität
in Munich, Germany with the working title «Writing processes and writing practices.
A conceptualization from a dialogical perspective». The project is funded by scholarships
of Universität Bayern e.V. and Ludwig-Maximilians-Universität.'

text: The paper presents a framework to optimise the design of work roll based on
the cooling performance. The framework develops meta-models from a set of finite
element analyses (FEA) of the roll cooling. A design of experiment technique is
used to identify the FEA runs. The research also identifies sources of uncertainties
in the design process. A robust evolutionary multi-objective evaluation technique
is applied to the design optimisation in constrained problems with real life uncertainty.
The approach handles uncertainties associated both with design variables and fitness
functions. Constraints violation within the neighbourhood of a design is considered
as part of a measurement for degree of feasibility and robustness of a solution.

text: Refinement of untimed TLM models into a timed HW/SW platform is a step by
step design process which is a trade-off between timing accuracy of the used models
and correct estimation of the final timing performance. The use of an RTOS on
the target platform is mandatory in the case real-time properties must be guaranteed.
Thus, the question is when the RTOS must be introduced in this step by step refinement
process. This paper proposes a four-level RTOS-aware refinement methodology that,
starting from an untimed TLM SystemC description of the whole system, progressively
introduce HW/SW partitioning, timing, device driver and RTOS functionalities,
till to obtain an accurate model of the final platform, where SW tasks run upon
an RTOS hosted by QEMU and HW components are modeled by cycle accurate TLM descriptions.
Each refinement level allows the designer to estimate more and more accurate timing
properties, thus anticipating design decisions without being constrained to leave
timing analysis to the final step of the refinement. The effectiveness of the
methodology has been evaluated in the design of two complex platforms.

text: In this article, we present a flexible simulation environment for embedded
real-time software refinement by a mixed level cosimulation. For this, we combine
the native speed of an abstract real-time operating system (RTOS) model in SystemC
with dynamic binary translation for fast Instruction Set Simulation (ISS) by QEMU.
In order to support stepwise RTOS software refinement from system level to the
target software, each task can be separately migrated between the native execution
and the ISS. By adapting the dynamic binary translation approach to an efficient
but yet very accurate synchronization scheme the overhead of QEMU user mode execution
is only factor two compared to native SystemC. Furthermore, the simulation speed
increases almost linearly according to the utilization of the task set abstracted
by the native execution. Hereby, the simulation time can be considerably reduced
by cosimulating just a subset of tasks on QEMU.

text: In developmental research, tutoring behavior has been identified as scaffolding
infants' learning processes. It has been defined in terms of child-directed speech
(Motherese), child-directed motion (Motionese), and contingency. In the field
of developmental robotics, research often assumes that in human-robot interaction
(HRI), robots are treated similar to infants, because their immature cognitive
capabilities benefit from this behavior. However, according to our knowledge,
it has barely been studied whether this is true and how exactly humans alter their
behavior towards a robotic interaction partner. In this paper, we present results
concerning the acceptance of a robotic agent in a social learning scenario obtained
via comparison to adults and 8-11 months old infants in equal conditions. These
results constitute an important empirical basis for making use of tutoring behavior
in social robotics. In our study, we performed a detailed multimodal analysis
of HRI in a tutoring situation using the example of a robot simulation equipped
with a bottom-up saliency-based attention model. Our results reveal significant
differences in hand movement velocity, motion pauses, range of motion, and eye
gaze suggesting that for example adults decrease their hand movement velocity
in an Adult-Child Interaction (ACI), opposed to an Adult-Adult Interaction (AAI)
and this decrease is even higher in the Adult-Robot Interaction (ARI). We also
found important differences between ACI and ARI in how the behavior is modified
over time as the interaction unfolds. These findings indicate the necessity of
integrating top-down feedback structures into a bottom-up system for robots to
be fully accepted as interaction partners.

text: In this paper, we derive an uncertainty decoding rule for automatic speech
recognition (ASR), which accounts for both corrupted observations and inter-frame
correlation. The conditional independence assumption, prevalent in hidden Markov
model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned
on the complete observed feature vector sequence. This is a more informative posterior
than one conditioned only on the current observation. The novel decoding is used
to obtain a transmission-error robust remote ASR system, where the speech capturing
unit is connected to the decoder via an error-prone communication network. We
show how the clean speech posterior can be computed for communication links being
characterized by either bit errors or packet loss. Recognition results are presented
for both distributed and network speech recognition, where in the latter case
common voice-over-IP codecs are employed.
