Target Pursuit

Aerial pursuit in nature is a complex task that involves interaction with targets in motion. To date, many researchers have analyzed aerial predation strategies used by different flying species for the pursuit and interception of targets such as a prey or a conspecific. In this article, we provide a brief review of these different predation strategies with the focus primarily on insects and bats that rely on different sensory variables (vision and sonar) for navigation. The Knowledge gained from studying these strategies can guide the development of bio-inspired approaches for navigation of engineered systems.

Flow Treatment

Of recent concern is the removal of toxic compounds in wastewaters, soils, and groundwater to concentrations in the low microgram per litre level or less. Threshold limits to bioremediation exist and must be considered in biological treatment schemes to achieve such limits. These limits may be related to reaction kinetics or thermodynamics. Techniques for removing compounds below threshold levels exist that rely on appropriate approaches such as plug flow treatment. Novel biological methods exist for removal of refractory contaminants to low levels. Examples are provided for removal of trace levels of chlorinated solvents, such as tetrachloroethene (PCE) and trichloroethene (TCE), that employ dehalorespiration under anaerobic conditions or cometabolism under aerobic conditions. These approaches are currently being used in engineered systems or through natural attenuation for remediation of soils and groundwater. Successful results offer insights for similar removals of trace chemicals in both aerobic and anaerobic biological systems for treatment of wastewaters and sanitary landfills.

In this paper, various variants of decomposition of tasks in a group of robots using cloud computing technologies are considered. The specifics of the field of application (teams of robots) and solved problems are taken into account. In the process of decomposition, the solution of one large problem is divided into a solution of a series of smaller, simpler problems. Three ways of decomposition based on linear distribution, swarm interaction and synthesis of solutions are proposed. The results of experimental verification of the developed decomposition algorithms are presented, the working capacity of methods for planning trajectories in the cloud is shown. The resulting solution is a component of the complex task of building effective teams of robots.

This chapter provides an overview of biological perceptual systems and their underlying computational principles focusing on the sensory sheets of the retina and cochlea and exploring how complex feature detection emerges by combining simple feature detectors in a hierarchical fashion. We also explore how the microcircuits of the neocortex implement such schemes pointing out similarities to progress in the field of machine vision driven deep learning algorithms. We see signs that engineered systems are catching up with the brain. For example, vision-based pedestrian detection systems are now accurate enough to be installed as safety devices in (for now) human-driven vehicles and the speech recognition systems embedded in smartphones have become increasingly impressive. While not being entirely biologically based, we note that computational neuroscience, as described in this chapter, makes up a considerable portion of such systems’ intellectual pedigree.

Moral Context

Chapter 2 takes up the complex task of formulating a conception of risk that can meet the twin desiderata of practicality and normativity. Though neither an unreconstructed subjective nor objective account of risk can, on its own, play the role we need it to play in a moral context, the accounts can be combined to take advantage of their respective strengths. Much of the chapter is therefore devoted to explaining how to overcome this recalibrated perspective-indifference. The chapter defends the perspective of a particular interpretation of the reasonable person, well-known from tort law, as a way of bringing determinacy to the characterization of risk. Defending this evidence-relative perspective while criticizing competing belief- and fact-relative perspectives, the chapter argues that it has the resources to meet the twin desiderata of practicality and normativity.
