Conducting research associated with mechanically ventilated patients often requires the recording of several biomedical signals to dispose of multiple sources of information to perform a robust analysis. This is especially important in the analysis of the relationship between pressure, volume and flow, signals available from mechanical ventilators, and other biopotentials such as the electromyogram of respiratory muscles, intrinsically related with the ventilatory process, but not commonly recorded in the clinical practice. Despite the usefulness of recording signals from multiple sources, few medical devices include the possibility of synchronizing its data with other provided by different biomedical equipment and some may use inaccurate sampling frequencies. Even thought a variant or inaccurate sampling rate does not affect the monitoring of critical patients, it restricts the study of simultaneous related events useful in research of respiratory system activity. In this article a device for temporal synchronization of signals recorded from multiple biomedical devices is described as well as its application in the study of patients undergoing mechanical ventilation with research purposes.

The fault detection and isolation problem is studied for a class of nonlinear systems. Under structural conditions, a bank of High-Order Sliding-Mode observers is proposed. The value of the equivalent output injection is used for detecting and isolating particular faults in the system. The proposed method provides finite-time isolation of actuator and plant faults. Simulation results support the proposed approach.

The IEEE RAS Ontologies for Robotics and Automation Working group is dedicated to developing a methodology for knowledge representation and reasoning in robotics and automation. As part of this working group, the Autonomous Robots sub-group is tasked with developing ontology modules for autonomous robots. This paper describes the work in progress on the development of ontologies for autonomous systems. For autonomous systems, the focus is on the cooperation, coordination, and communication of multiple unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), and autonomous underwater vehicles (AUVs). The ontologies serve as a framework for working out concepts of employment with multiple vehicles for a variety of operational scenarios with emphasis on collaborative and cooperative missions. © 2012 IEEE.

The current medical tendency in the rehabilitation field is to try and physically rehabilitate people with cardiovascular illnesses by exercising their injured systems. Because people's heat rate response is distinct at different times according to the demand of physical effort, it is necessary to know the relation between the effort (training device power/resistance) and the patient's heartbeat. This work deals with the study of Artificial Neural Networks to identify the physiologic behavior of a patient during a supervised training session. In this way, the Neural Identifier can be used in an Intelligent control System in order to optimize the patient training therapy. In this paper, we present the first results in the identification of the relationship in time, between the demanded exercise (machine resistance) and the heart rate of the patient. © 2011 Springer-Verlag Berlin Heidelberg.

This paper investigates mechanisms underlying cooperative behaviour in a group of miniature mobile robots around the problem of coordinating a group of robots to push collectively a heavy object. Numerous solutions to this problem have been proposed [5,7,4]. The performance of these however typically deteriorates as the number of robots increases to more than a dozen. The cause of this is often said to be robot interference—there are many robots but insufficient space to manipulate the object effectively. The situation is particular difficult when the object itself occludes the view of robots [3]. In this case, robots can benefit from division of labour (e.g., see [2]). Here, we take inspiration of the division of labour in teams of humans pushing a large object towards a target location: persons who can see the target push the box only when the transporting direction needs to be corrected, while all other persons simply push the box forward. The two roles in this cooperation are indicated in Fig. 1(a). © 2011, Springer-Verlag Berlin Heidelberg.

A dynamical system can exhibit structure on multiple levels. Different system representations can capture different elements of a dynamical system's structure. We consider LTI input-output dynamical systems and present four representations of structure: complete computational structure, subsystem structure, signal structure, and input output sparsity structure. We then explore some of the mathematical relationships that relate these different representations of structure. In particular, we show that signal and subsystem structure are fundamentally different ways of representing system structure. A signal structure does not always specify a unique subsystem structure nor does subsystem structure always specify a unique signal structure. We illustrate these concepts with a numerical example. © 2011 AACC American automatic control Council.

Drift-diffusion analysis of neutrophil migration during inflammation resolution in a zebrafish model

Neutrophils must be removed from inflammatory sites for inflammation to resolve. Recent work in zebrafish has shown neutrophils can migrate away from inflammatory sites, as well as die in situ. The signals regulating the process of reverse migration are of considerable interest, but remain unknown. We wished to study the behaviour of neutrophils during reverse migration, to see whether they moved away from inflamed sites in a directed fashion in the same way as they are recruited or whether the inherent random component of their migration was enough to account for this behaviour. Using neutrophil-driven photoconvertible Kaede protein in transgenic zebrafish larvae, we were able to specifically label neutrophils at an inflammatory site generated by tailfin transection. The locations of these neutrophils over time were observed and fitted using regression methods with two separate models: pure-diffusion and drift-diffusion equations. While a model hypothesis test (the F-test) suggested that the datapoints could be fitted by the drift-diffusion model, implying a fugetaxis process, dynamic simulation of the models suggested that migration of neutrophils away from a wound is better described by a zero-drift, diffusion process. This has implications for understanding the mechanisms of reverse migration and, by extension, neutrophil retention at inflammatory sites. © Copyright 2012 Geoffrey R. Holmes et al.
