    This study developed a multiple effective visuo-haptic surgical engine to handle a variety of surgical manipulations in real-time. Soft tissue models are based on biomechanical experiment and continuum mechanics for greater accuracy. Such models will increase the realism of future training systems and the VR/AR/MR implementations for the operating room

    A Collision Detection-Based Wandering Method for Equipment Deploy Scene in Land Reclamation Area of Mining Dump

    No full text
    Part 1: Decision Support Systems, Intelligent Systems and Artificial Intelligence ApplicationsInternational audienceAiming at developing a simple and efficient collision detection method to support the wandering in equipment deploy scene in land reclamation area of mining dump. This paper presents an efficient algorithm for collision detection in the waste dump land reclamation equipment deploy scene using a bounding volume nestification which consists of an oriented bounding boxes (OBBs) enhanced with axially aligned bounding boxes (AABBs). This approach combines the compactness of OBBs and the simplicity of AABBs. The majority of distant objects are separated using the simpler AABB tests. The remaining objects are in close proximity, where OBBs test is needed to detect. Implementation results show that our algorithm achieves considerable speedup in most cases

    """Advances in Raw Material Industries for Sustainable Development Goals"" presents the results of joint scientific research conducted in the context of the Russian-German Raw Materials Forum. Today Russia and Germany are exploring various forms of cooperation in the field of mining, geology, mineralogy, mechanical engineering and energy. Russia and Germany are equally interested in expanding cooperation and modernizing the economy in terms of sustainable development. The main theme of this article collection is connected with existing business ventures and ideas from both Russia and Germany. In this book the authors regard complex processes in mining industry from various points of view, including: - modern technologies in prospecting, exploration and development of mineral resources - progressive methods of natural and industrial mineral raw materials processing - energy technologies and digital technologies for sustainable development - cutting-edge technologies and innovations in the oil and gas industry. Working with young researchers, supporting their individual professional development and creating conditions for their mobility and scientific cooperation are essential parts of Russian-German Raw Materials Forum founded in Dresden 13 years ago. This collection represents both willingness of young researchers to be involved in large-scale international projects like Russian-German Raw Material Forum and the results of their long and thorough work in the promising areas of cooperation between Russia and Germany.

    Proceedings of the Seventh Annual Summer Conference. NASA/USRA: University Advanced Design Program

    Get PDF
    The Advanced Design Program (ADP) is a unique program that brings together students and faculty from U.S. engineering schools with engineers from the NASA centers through integration of current and future NASA space and aeronautics projects into university engineering design curriculum. The Advanced Space Design Program study topics cover a broad range of projects that could be undertaken during a 20-30 year period beginning with the deployment of the Space Station Freedom. The Advanced Aeronautics Design Program study topics typically focus on nearer-term projects of interest to NASA, covering from small, slow-speed vehicles through large, supersonic passenger transports and on through hypersonic research vehicles. Student work accomplished during the 1990-91 academic year and reported at the 7th Annual Summer Conference is presented

    Heidegger and the Ethics of the Earth: Eco-Phenomenology in the Age of Technology

    Get PDF
    Martin Heidegger came to see the history of Western metaphysics as a series of ontotheological epochs. These epochs, he argues, culminate in the age informed by the metaphysics of Friedrich Nietzsche. According to this ontotheological paradigm, entities are nothing more than meaningless resources to be optimized. This paper argues that this is the source of the environmental crises we face. In order to see our way through and beyond this nihilistic ontotheological age, we must recognize the ontological source of all existence, that which Heidegger called being as such. The philosophical tradition of phenomenology offers us an ideal method for cultivating an openness to and an appreciation of the existence of any particular entity as an instantiation of the inexhaustibly meaningful being as such. By being appropriately open, we come to have a more authentic relationship to the world and the entities within it, including ourselves. Since any ethics is built upon ontology, reorienting our ontological perspectives in this way makes possible the development of an environmental ethic that can help us resolve the ethical dilemmas we face on the environmental front

    The Counter-testimony of the Maker

    The chapter begins with the question of critique, mainly how and why does one critique but more importantly why does no one critique effectively anymore. Such is a sentiment echoed by Bruno Latour in the paper Why has Critique Run out of Steam? He states: “It does not seem to me that we have been as quick, in academia, to prepare ourselves for new threats, new dangers, new tasks, new targets. Are we not like those mechanical toys that endlessly make the same gesture when everything else has changed around them?”(Latour, 2004:225). According to Latour, the absence of principles is to blame. As he puts it, critique has battered through all claims to a ground and the lack of a sure ground argument has backfired. The result is that there isn’t even a sure ground for criticism. Without a ground, it’s hard to differentiate a rigorous critical claim from a conspiracy theory. That’s why conspiracy theory books are best sellers. Latour mourns the death of critique. In its remnants lies a whole industry denying the Apollo program. My claim is that the absence of principles transforms critique into an issue around the strength of evidence and the credibility of the testimony. Effective critique is synonymous with a counter-testimony of a reliable witness. A witness is someone who is present at the time of an event, often a crime, and is able to testify before the law. They are able to give direct evidence in relation to the events. However, they often rely on foggy memories and blurred vision. It is not too difficult for the defence or prosecution to put the reliability or credibility of the witness in doubt. Here is where the role of making comes into play. More often than not, in the post-critical age, a testimony, or counter-testimony, is not simply uttered but is rather constructed. Latour is the first to admit that a critique has to be made. As such the eyewitness is no longer a person but a photograph, a video or other forms of surveillance. Juries are more decisive when they are presented with the facts, the evidence, more often submitted as objects as opposed to a fuzzy testimony of a witness. Critique, or counter-testimony, is a material process enabled by infrastructure. Is a practice-based question of physics, chemistry and the material forms of agency. Given all this this chapter explores further the role of critical making as counter-testimony. From aesthetic practices of forensics, counter-forensics to the role of labs in media archaeology and investigative practices, I will tell the story of makers that present their objects as a counter-narrative to pressing socio-political issues. More importantly, however, I will address the issue of how critical making practices can establish credibility in a world of fakes and loss of belief
