Positioning is a fundamental issue in mobile robot applications, and it can be achieved in multiple ways. Among these methods, triangulation based on angle measurements is widely used, robust, accurate, and flexible. This paper presents BeAMS, a new active beacon-based angle measurement system used for mobile robot positioning. BeAMS introduces several major innovations. One innovation is the use of a unique unsynchronized channel with On-Off Keying modulated infrared signals to measure angles and to identify the beacons. We also introduce a new mechanism to measure angles: our system detects a beacon when it enters and leaves an angular window. We show that the estimator resulting from the center of this angular window provides an unbiased estimate of the beacon angle. A theoretical framework for a thorough performance analysis of BeAMS is provided. We establish the upper bound of the variance and validate this bound through experiments and simulations; the overall error measure of BeAMS is lower than 0.24 deg for an acquisition rate of 10 Hz. In conclusion, BeAMS is a low power, flexible, and robust solution for angle measurement, and a reliable component for robot positioning. [less ▲]

Introduction: Functional time-varying cardiac elastances (FTVE) contain a rich amount of information about the specific cardiac state of a patient. However, a FTVE waveform is very invasive to directly measure, and is thus currently not used in clinical practice. This paper presents a method for the estimation of a patient specific FTVE, using only metrics that are currently available in a clinical setting. Method: Correlations are defined between invasively measured FTVE waveforms and the aortic and pulmonary artery pressures from 2 cohorts of porcine subjects, 1 induced with pulmonary embolism, the other with septic shock. These correlations are then used to estimate the FTVE waveform based on the individual aortic and pulmonary artery pressure waveforms, using the “other” dysfunction’s correlations as a cross validation. Results: The cross validation resulted in 1.26% and 2.51% median errors for the left and right FTVE respectively on pulmonary embolism, while the septic shock cohort had 2.54% and 2.90% median errors. Conclusions: The presented method accurately and reliably estimated a patient specific FTVE, with no added risk to the patient. The cross validation shows that the method is not dependent on dysfunction and thus has the potential for generalisation beyond pulmonary embolism and septic shock. [less ▲]

Using data from clinical research in applied psychoanalysis concerning lesbian couples undertaking Artificial Insemination by Donor (AID), this article explores the position of the third as it appears in the family project of lesbian couples. The third is explored by analysing fantasised constructions surrounding the image of the anonymous donor, the impact of the medical act of insemination on the women’s psychic economy and the search for other promising bases for triangulation. This article highlights the complexity of the issue of the third in same-sex parenting. It also addresses the debate on the notion of thirdness in contemporary psychoanalytic literature. [less ▲]

When philosophers deal with the issue of the difference between human and animal beings, there is always a double ‘‘we’’ that imposes itself: ‘‘we’’ know that ‘‘we’’ are different. In order to resist these ‘‘we’s’’ the author has explored certain situations in which human and animals work together, and more extensively the everyday practices of cow and pig breeders. Interviewing the breeders, however, highlights an important issue: might the question of ‘‘the’’ difference, as philosophers have outlined it, be of interest to those who work with animals? Letting them construct ‘‘their’’ questions, we learn that these practices are best described in terms of achievement. Therefore, the questions that breeders think should be addressed are not the differences between human and non-human beings but rather the differences between situations, which offer both humans and animals different opportunities to accomplish subjectivities.
