text: 'This article presents analyses of excerpts from a study on writing conducted
in a dialogical perspective. The study’s material was collected by the auto-confrontation
method: writers were videotaped during their work and afterwards confronted with
their writing activities. Microanalysis of the material attends to how inner dialogues
during writing are “refracted” (Voloshinov) in auto-confrontation. Bakhtin’s notion
of the chronotope (time-and-space) as the main tool of analysis helps to discern
the changing contexts and position constellations utterances are valid for. It
thus sheds light on the positioning movements performed by the writing selves
through language. The analyses show various utterance movements traversing the
chronotopes involved, ranging from refractions of movements between the writers’
inner dialogues and their texts to retrospective imperatives with a developmental
potential. This “dialogical volume” of speech activity presenting itself in writing
can contribute to our understanding of the interplay of language and the self.'

text: In this paper, we consider the Maximum Likelihood (ML) estimation of the parameters
of a GAUSSIAN in the presence of censored, i.e., clipped data. We show that the
resulting Expectation Maximization (EM) algorithm delivers virtually biasfree
and efficient estimates, and we discuss its convergence properties. We also discuss
optimal classification in the presence of censored data. Censored data are frequently
encountered in wireless LAN positioning systems based on the fingerprinting method
employing signal strength measurements, due to the limited sensitivity of the
portable devices. Experiments both on simulated and real-world data demonstrate
the effectiveness of the proposed algorithms.

text: In this paper we present a robust location estimation algorithm especially
focused on the accuracy in vertical position. A loosely-coupled error state space
Kalman filter, which fuses sensor data of an Inertial Measurement Unit and the
output of a Global Positioning System device, is augmented by height information
from an altitude measurement unit. This unit consists of a barometric altimeter
whose output is fused with topographic map information by a Kalman filter to provide
robust information about the current vertical user position. These data replace
the less reliable vertical position information provided the GPS device. It is
shown that typical barometric errors like thermal divergences and fluctuations
in the pressure due to changing weather conditions can be compensated by the topographic
map information and the barometric error Kalman filter. The resulting height information
is shown not only to be more reliable than height information provided by GPS.
It also turns out that it leads to better attitude and thus better overall localization
estimation accuracy due to the coupling of spatial orientations via the Direct
Cosine Matrix. Results are presented both for artificially generated and field
test data, where the user is moving by car.

text: In this paper we present a novel vehicle tracking algorithm, which is based
on multi-level sensor fusion of GPS (global positioning system) with Inertial
Measurement Unit sensor data. It is shown that the robustness of the system to
temporary dropouts of the GPS signal, which may occur due to limited visibility
of satellites in narrow street canyons or tunnels, is greatly improved by sensor
fusion. We further demonstrate how the observation and state noise covariances
of the employed Kalman filters can be estimated alongside the filtering by an
application of the Expectation-Maximization algorithm. The proposed time-variant
multi-level Kalman filter is shown to outperform an Interacting Multiple Model
approach while at the same time being computationally less demanding.

text: In this paper we present a novel vehicle tracking method which is based on
multi-stage Kalman filtering of GPS and IMU sensor data. After individual Kalman
filtering of GPS and IMU measurements the estimates of the orientation of the
vehicle are combined in an optimal manner to improve the robustness towards drift
errors. The tracking algorithm incorporates the estimation of time-variant covariance
parameters by using an iterative block Expectation-Maximization algorithm to account
for time-variant driving conditions and measurement quality. The proposed system
is compared to an interacting multiple model approach (IMM) and achieves improved
localization accuracy at lower computational complexity. Furthermore we show how
the joint parameter estimation and localizaiton can be conducted with streaming
input data to be able to track vehicles in a real driving environment.

text: A combination of GPS (global positioning system) and INS (inertial navigation
system) is known to provide high precision and highly robust vehicle localization.
Notably during times when the GPS signal has a poor quality, e.g. due to the lack
of a sufficiently large number of visible satellites, the INS, which may consist
of a gyroscope and an odometer, will lead to improved positioning accuracy. In
this paper we show how velocity information obtained from GSM (global system for
mobile communications) signalling, rather than from a tachometer, can be used
together with a gyroscope sensor to support localization in the presence of temporarily
unavailable GPS data. We propose a sensor fusion system architecture and present
simulation results that show the effectiveness of this approach.

text: In this paper, we propose a novel similarity measure to be used for localizing
mobile terminals by comparing measured signal power levels with a database of
predictions. The proposed measure provides the possibility to incorporate inherent
information about signal power level measurements requested by the serving base
station but not reported by the mobile terminal. Increased positioning accuracy
was observed both in simulations and with real field data

text: "Location-aware services for private use such as GPS-\r\nbased navigation
systems and GSM-based offerings\r\nhave become quite a success for outdoor applications,\r\nwhile
indoor positioning systems are still mainly\r\nemployed for professional use only.
The main reasons\r\nare cost issues and the complexity of setup and\r\nmaintenance
of those systems. In this paper we\r\npresent CaMPTrack (Camera-based Multiple
Person\r\nTracker), a prototype of a webcam-based positioning\r\nsystem and discuss
its application and development\r\nchallenges."

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 controlled to get an optimized drive that is not oversized
and costly.'

text: Current navigation systems like GPS (Global Positioning System) and its Russian
counterpart GLONASS (Global Navigation Satellite System) only evaluate the direct
signal path. The receivers treat the reflected paths also reaching the receiver
antenna as disturbance which has to be suppressed. Multipath affects the tracking
accuracy by resulting in a degeneration of the S-curve of the DLL (delay locked
loop). Nowadays the future European systems GALILEO and GPSIIF/III with two new
signals are on the way to the market and it is time to think about new receiver
structures. Therefore we investigated if it is possible to use multipath for navigation
constructively.
