text: Application of prognostics and health management (PHM) in the field of Proton
Exchange Membrane (PEM) fuel cells is emerging as an important tool in increasing
the reliability and availability of these systems. Though a lot of work is currently
being conducted to develop PHM systems for fuel cells, various challenges have
been encountered including the self-healing effect after characterization as well
as accelerated degradation due to dynamic loading, all which make RUL predictions
a difficult task. In this study, a prognostic approach based on adaptive particle
filter algorithm is proposed. The novelty of the proposed method lies in the introduction
of a self-healing factor after each characterization and the adaption of the degradation
model parameters to fit to the changing degradation trend. An ensemble of five
different state models based on weighted mean is then developed. The results show
that the method is effective in estimating the remaining useful life of PEM fuel
cells, with majority of the predictions falling within 5\% error. The method was
employed in the IEEE 2014 PHM Data Challenge and led to our team emerging the
winner of the RUL category of the challenge.

text: The accuracy of automatic speech recognition systems in noisy and reverberant
environments can be improved notably by exploiting the uncertainty of the estimated
speech features using so-called uncertainty-of-observation techniques. In this
paper, we introduce a new Bayesian decision rule that can serve as a mathematical
framework from which both known and new uncertainty-of-observation techniques
can be either derived or approximated. The new decision rule in its direct form
leads to the new significance decoding approach for Gaussian mixture models, which
results in better performance compared to standard uncertainty-of-observation
techniques in different additive and convolutive noise scenarios.

text: In this paper we present a speech presence probability (SPP) estimation algorithmwhich
exploits both temporal and spectral correlations of speech. To this end, the SPP
estimation is formulated as the posterior probability estimation of the states
of a two-dimensional (2D) Hidden Markov Model (HMM). We derive an iterative algorithm
to decode the 2D-HMM which is based on the turbo principle. The experimental results
show that indeed the SPP estimates improve from iteration to iteration, and further
clearly outperform another state-of-the-art SPP estimation algorithm.

text: This study shows how venture capital investors can identify potential biases
in multi-year management forecasts before an investment decision and derive significantly
more accurate failure predictions. By advancing a cross-sectional projection method
developed by prior research and using firm-specific information in financial statements
and business plans, we derive benchmarks for management revenue forecasts. With
these benchmarks, we estimate forecast errors as an a priori measure of biased
expectations. Using this measure for our proprietary dataset on venture-backed
start-ups in Germany, we find evidence of substantial upward forecast biases.
We uncover that firms with large forecast errors fail significantly more often
than do less biased entrepreneurs in years following the investment. Overall,
our results highlight the implications of excessive optimism and overconfidence
in entrepreneurial environments and emphasize the relevance of accounting information
and business plans for venture capital investment decisions.

text: Piezoelectric inertia motors use the inertia of a body to drive it by means
of a friction contact in a series of small steps. These motors can operate in
``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
a Coulomb friction model is sufficient in many cases, but numerical simulation
requires microscopic time steps. This contribution proposes a much faster simulation
technique using one evaluation per period of the excitation signal. The proposed
technique produces results very close to those of timestep simulation for ultrasonics
inertia motors and allows direct determination of the steady-state velocity of
an inertia motor from the motion profile of the driving part. Thus it is a useful
simulation technique which can be applied in both analysis and design of inertia
motors, especially for parameter studies and optimisation.

text: 'Employing time series of single-name CDS market spreads from 29 European
banks located in the EU-12 plus Switzerland and the UK over the period from January
2004 through September 2010 this paper analyses the relationship between increasing
sovereign risk and bank-specific CDS pricing. Results from calculating relative
CDS spread deviations (model minus market spreads) initially reveal a price bubble
in the European CDS market until the beginning of the financial crisis in mid-2007.
From this point in time the gap narrows remarkably during the financial crisis
and sovereign debt crisis period. Corresponding to these findings, the empirical
analysis reveals a negative impact of sovereign risk on calculated CDS spread
differentials indicating a spill-over effect between sovereign risk and bank risk
and hence, a positive effect on bank-specific CDS pricing. Further analyses reveal
that the perception of sovereign risk is not crisis- but country-dependent suggesting
that bank-specific CDS market spreads may already include a premium to cover sovereign
risk from PIIGS countries during the pre-crisis period in Europe. '

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: Attended stimuli are perceived as occurring earlier than unattended stimuli.
This phenomenon of prior entry is usually identified by a shift in the point of
subjective simultaneity (PSS) in temporal order judgements (TOJs). According to
its traditional psychophysical interpretation, the PSS coincides with the perception
of simultaneity. This assumption is, however, questionable. Technically, the PSS
represents the temporal interval between two stimuli at which the two alternative
TOJs are equally likely. Thus it also seems possible that observers perceive not
simultaneity, but uncertainty of temporal order. This possibility is supported
by prior-entry studies, which find that perception of simultaneity is not very
likely at the PSS. The present study tested the percept at the PSS in prior entry,
using peripheral cues to orient attention. We found that manipulating attention
caused varying temporal perceptions around the PSS. On some occasions observers
perceived the two stimuli as sim

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: Comments on an article by Jan Theeuwes (see record [rid]2010-20897-002[/rid]).
Theeuwes summarizes an impressive number of studies demonstrating interference
by irrelevant visual singletons in computer experiments with humans. Theeuwes
assumes that this salience-driven capture of attention is fast and occurs within
150 ms since singleton onset, during the feed-forward phase of visual processing.
In contrast to Theeuwes, we think that top–down contingent capture is the rule
and explains initial and fast attention capture effects in the first feed-forward
phase of visual processing. During a later phase and under some conditions exogenous
capture of attention possibly follows. At the same time, we propose that the evidence
presented by Theeuwes fails to support exogenous orienting because it fails to
exclude a top–down contingent capture explanation. We present our arguments in
two sections. One major source of evidence for top–down controlled attentional
capture during the feed-forward

text: Today, mobile and embedded real time systems have to cope with the migration
and allocation of multiple software tasks running on top of a real time operating
system (RTOS) residing on one or several processors. For scaling of each task
set and processor configuration, instruction set simulation and worst case timing
analysis are typically applied. This paper presents a complementary approach for
the verification of RTOS properties based on an abstract RTOS-Model in SystemC.
We apply IEEE P1850 PSL for which we present an approach and first experiences
for the assertion-based verification of RTOS properties.

text: In automatic speech recognition, hidden Markov models (HMMs) are commonly
used for speech decoding, while switching linear dynamic models (SLDMs) can be
employed for a preceding model-based speech feature enhancement. In this paper,
these model types are combined in order to obtain a novel iterative speech feature
enhancement and recognition architecture. It is shown that speech feature enhancement
with SLDMs can be improved by feeding back information from the HMM to the enhancement
stage. Two different feedback structures are derived. In the first, the posteriors
of the HMM states are used to control the model probabilities of the SLDMs, while
in the second they are employed to directly influence the estimate of the speech
feature distribution. Both approaches lead to improvements in recognition accuracy
both on the AURORA2 and AURORA4 databases compared to non-iterative speech feature
enhancement with SLDMs. It is also shown that a combination with uncertainty decoding
further enhances performance.

text: Today, mobile and embedded real-time systems have to cope with the migration
and allocation of multiple software tasks running on top of a real-time operating
system (RTOS) residing on one or multiple system processors. Abstract RTOS simulations
and timing analysis applies for fast and early estimation to configure it towards
the individual needs of the application and environment. In this context, a high
accuracy of the simulation compared to an instruction set simulation (ISS) is
of key importance. In this paper, we investigate the accuracy of abstract RTOS
simulation and compare it to ISS and the behavior of the physical system. We show
that we can reach an increased accuracy of the simulation when we inject noise
into the time model. Our results indicate that it is sufficient to inject uniformly
distributed random time values to the RTOS real-time clock.

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.

text: In this paper, we experimentally evaluate algorithms for velocity estimation
of a GSM 900 mobile terminal which are based on the analysis of the statistical
properties of the fast fading process. It is shown how theses statistics can be
obtained from the training sequences present in downlink transmission bursts without
establishing an active connection. Realistic simulations of a GSM channel according
to the COST 207 channel models have been conducted. These models incorporate effects
like multipath propagation, fading, cochannel interference and additive noise.
It is shown that velocity estimation by searching for the maximum slope of the
power density spectrum of the fast fading performs best.

text: 'The Fehrer-Raab effect (simple reaction time is unaffected by metacontrast
masking of the test stimulus) seems to imply that a stimulus can trigger a voluntary
reaction without reaching a conscious representation. However, it is also possible
that the mask triggers the reaction, and that the masked test stimulus causes
a focussing of attention from which processing of the mask profits, thus reaching
conscious representation earlier. This is predicted by the Weather Station Model
of visual masking. Three experiments tested this explanation. Experiment 1 showed
that the masked test stimulus caused a temporal shift of the mask. Experiment
2 showed that the reaction in the Fehrer-Raab effect was not exclusively triggered
by a conscious representation of the test stimulus: the mask was involved in evoking
the reaction. Experiment 3 again revealed a temporal shift of the mask. However,
the shift was only about half as large as the Fehrer-Raab effect. The psychometric
functions suggested tha'

text: "StateCharts are well accepted for embedded systems\r\nspecification for various
applications. However, for the\r\nspecification of complex systems they have several\r\nlimitations.
In this article, we present a novel approach to\r\nefficiently execute an UML
2.0 subset for embedded real-\r\ntime systems implementation with focus on hardware\r\ninterrupts,
software exceptions, and timeouts. We\r\nintroduce a UML Virtual Machine, which
directly\r\nexecutes sequence diagrams, which are embedded into\r\nhierarchically
structured state transition diagrams.\r\nWhereas state diagrams are directly executed
as\r\nEmbedded State Machines (ESMs), sequence diagrams\r\nare translated into
UVM Bytecode. The final UVM\r\nexecution is performed by the interaction of the
ESM and\r\nthe Bytecode Interpreter. Due to our completely model-\r\nbased approach,
the UVM runtime kernel is easily\r\nadaptable and scalable to different scheduling
and\r\nmemory management strategies."
