—This paper describes a method for the automatic self-calibration of a 3D Laser sensor. We wish to acquire crisp point clouds and so we adopt a measure of crispness to capture point cloud quality. We then pose the calibration problem as the task of maximising point cloud quality. Concretely, we use Rényi Quadratic Entropy to measure the degree of(More)
Research in the emergency setting involving patients with acute clinical conditions is needed if there are to be advances in diagnosis and treatment. But research in these areas poses ethical and practical challenges. One of these is the general inability to obtain informed consent due to the patient's lack of mental capacity and insufficient time to(More)
A recent article from Archives of Disease in Childhood outlined problems with the act of gaining child assent for research participation. However the arguments used in the article are incomplete or misguided. Rather than being harmful, assent should be seen as an ethically-appropriate way in which we can engage with the child about his participation in(More)
The use of charged-particle radiation therapy (CPRT) is an increasingly important development in the treatment of cancer. One of the most pressing controversies about the use of this technology is whether randomised controlled trials are required before this form of treatment can be considered to be the treatment of choice for a wide range of indications.(More)
This paper describes the design, build, automatic self-calibration and evaluation of a 3D Laser sensor using conventional parts. Our goal is to design a system, which is an order of magnitude cheaper than commercial systems , with commensurate performance. In this paper we adopt point cloud " crispness " as the measure of system performance that we wish to(More)
Much has been written in the last decade about how we should understand the value of the sociology of bioethics. Increasingly the value of the sociology of bioethics is interpreted by its advocates directly in terms of its relationship to bioethics. It is claimed that the sociology of bioethics (and related disciplinary approaches) should be seen as an(More)
This issue of the journal contains three sets of papers clustered around three issues: organs, genetic testing and moral enhancement. Michael Hauskeller has written a guest editorial on the issue of moral enhancement (see page 289) and linked to the Author Meets Critics section of the issue (see pages 338–352). In what follows I will make a few remarks on(More)
