Mapping Systems

The vehicles of the conditional, high, and full automation levels have a common unique sensor, the map. The term map has undergone a significant change because the spatial resolution has been increased considerably, the road infrastructure and its neighborhood are represented with higher accuracy in 3D. The development of these vehicles requires enormous efforts, where computer-based techniques, like the simulations, can offer a helping hand. The autonomous simulations will be supported by high-quality map information, which generates interest in the best field data-capturing techniques. The paper provides an overview of the available modern surveying methodologies, then introduces the most preferred data formats – both in physical information storage and in exchanging information content between mapping systems. Some examples are presented to demonstrate the usage of the relevant map-making outputs in automotive simulators.

The Subject

The issue in today’s education is that teachers may be engaged in the role of teaching but not necessarily facilitating the learning process. This study was created to explore tools that will encourage and maximize student learning in mathematics. It highlights the advantages and possible disadvantages of incorporating digital technology into mathematics. Students tend to lose focus in the subject being taught due to a lack of interest. This is why curriculum reform is needed, in order to awaken and develop powers of creativity in teaching. I gathered an assortment of information through online surveys, interviews and field experience. My findings showed that positive math learning experiences were created through engaging students in math activities with the use of digital technology. The development of digital technology in curriculums such as math may just be the road to a successful curriculum reform. One that encourages and engages student curiosity, individuality and their creativity.

This paper considers car driver monitoring systems that measure bodies to infer and react to emotions and other affective states. Situated within social trends in personalisation and automation, developers of driver monitoring systems promise increased safety on the road and comfort for cabin occupants. The impetus is threefold, namely: (1) European road safety policy seeks to vastly reduce road deaths using computational surveillance; (2) interest in the role of safety solutions based on in-cabin sensing of emotion and affective states of drivers and passengers; and 3) autonomous driving trends changing the nature of interactions between vehicle and driver. These systems are of special interest because they are backed by policy and standards initiatives, not least the European Union’s Vision Zero policy that seeks to reduce road death to zero, and industry-oriented safety programmes like the New Car Assessment Programme (NCAP). Informed by 13 expert interviews with interviewees working in and around in-cabin sensing developments, this paper identifies and explores features of emergent in-cabin profiling through emotional AI and biometric measures. It then carries ambivalent insights found into analysis of applicable European regulations, also finding a deep ambivalence in the politics of Emotional AI for interior sensing of cabins and occupants.

Free Interaction

Action anticipation, intent prediction, and proactive behavior are all desirable characteristics for autonomous driving policies in interactive scenarios. Paramount, however, is ensuring safety on the road: a key challenge in doing so is accounting for uncertainty in human driver actions without unduly impacting planner performance. This article introduces a minimally interventional safety controller operating within an autonomous vehicle control stack with the role of ensuring collision-free interaction with an externally controlled (e.g., human-driven) counterpart while respecting static obstacles such as a road boundary wall. We leverage reachability analysis to construct a real-time (100 Hz) controller that serves the dual role of (i) tracking an input trajectory from a higher-level planning algorithm using model predictive control, and (ii) assuring safety by maintaining the availability of a collision-free escape maneuver as a persistent constraint regardless of whatever future actions the other car takes. A full-scale steer-by-wire platform is used to conduct traffic-weaving experiments wherein two cars, initially side-by-side, must swap lanes in a limited amount of time and distance, emulating cars merging onto/off of a highway. We demonstrate that, with our control stack, the autonomous vehicle is able to avoid collision even when the other car defies the planner’s expectations and takes dangerous actions, either carelessly or with the intent to collide, and otherwise deviates minimally from the planned trajectory to the extent required to maintain safety.

Medical students depend on illustration to learn anatomical facts and details that may be too subtle for the written or spoken word. For surgical disciplines, learners rely on tools such as language, 2-dimensional illustrations, and 3-dimensional models to pass on important concepts. Although a photograph can convey factual information, illustration can highlight and educate the pertinent details for understanding surgical procedures, neurovascular structures, and the pathological disease processes. In order to understand the current role of medical illustration in education, one needs to look to the past to see how art has helped solve communication dilemmas when learning medicine. This paper focuses on Max Brodel (1870-1941), a German-trained artist who eventually immigrated to the United States to pursue his career as a medical illustrator. Shortly after his arrival in Baltimore, Brodel made significant contributions to medical illustration in Gynecology at John Hopkins University, and eventually in other fields of medicine such as Urology and Otolaryngology. Brodel is recognized as one of America’s most distinguished medical illustrators for creating innovative artistic techniques and founding the profession of medical illustration. Today, animated computer based art is synergistically used with medical illustration to educate students about anatomy. Some of the changes that have occurred with the advancement of computer technology will be highlighted and compared to a century ago, when illustrations were used for teaching anatomy due to the scarcity of cadavers.

Dramatic advances in therapy for pulmonary arterial hypertension (PAH) in the last 20 years have improved survival from a median of 2.5 years in the pretreatment era to 7.5 years currently. However, impressive as that may seem, it is important to note that a median survival of 7.5 years is equivalent to that of surgically resected non-small cell lung cancer, thus underscoring the importance of lung transplantation as a treatment option in patients with PAH. In this edition of Advances, Edelman has reviewed the pathway to transplantation for patients with PAH, detailing the recommendations for timing of referral, listing for lung transplantation, the role of the lung allocation score in allocating a donor organ, and the outcome of lung transplantation.

After reviewing some of the recent literature on non-causal and mathematical explanation, this chapter develops an argument as to why renormalization group (RG) methods should be seen as providing non-causal, yet physical, information about certain kinds of systems/phenomena. The argument centres on the structural character of RG explanations and the relationship between RG and probability theory. These features are crucial for the claim that the non-causal status of RG explanations involves something different from simply ignoring or “averaging over” microphysical details—the kind of explanations common to statistical mechanics. The chapter concludes with a discussion of the role of RG in treating dynamical systems and how that role exemplifies the structural aspects of RG explanations which in turn exemplifies the non-causal features.

This chapter explores the role geo-location technologies may play on the road towards achieving jurisdictional interoperability. The relevant technologies involved are introduced briefly, their accuracy examined, and an overview is provided of their use, including the increasingly common use of so-called geo-blocking. Attention is then given to perceived and real concerns stemming from the use of geo-location technologies and how these technologies impact international law, territoriality, and sovereignty, as well as to the role these technologies may play in law reform. The point is made that the current ‘effect-focused’ rules in both private international law and public international law (as those disciplines are traditionally defined), are likely to continue to work as an incentive for the use of geo-location technologies.

The article examines the correlation between the world and the word in two novels which engage with a post-apocalyptic scenario: David Markson’s Wittgenstein’s Mistress (1988) and Cormac McCarthy’s The Road (2006). Shifting the focus from the very event of catastrophe to the notion of survival through memory and storytelling, both novels problematize the strained relationship between language and reality in an increasingly diminished and dehumanized world. My aim is to investigate the limits of language as well as its capacity to withstand the chaos, loss, trauma, and death that follow the apocalypse. The issues to be considered include the influence of external experience on forms of communication, the role of central metaphors (the archive and the museum in Markson’s novel; cinders and the road in McCarthy’s) and their relation to the form of both novels, as well as the word’s (in)capacity to preserve human values and hopes. Both novels will be discussed as deconstructionist projects in which language becomes a habitat at once impossible and life-preserving: in Wittgenstein’s Mistress it plays the role of both home and prison, whereas in The Road it functions as messianic discourse which simultaneously carries, propels and extinguishes the human hope for a transcendental reality beyond the post-apocalyptic emptiness and doubt.

The Relationship

Our spatial mental representations allow us to give refined descriptions of the environment in terms of the relative locations and distances between objects and landmarks. In this study, we investigated the effects of familiarity with the everyday environment, in terms of frequency of exploration and mode of transportation, on categorical and coordinate spatial relations, on young and elderly participants, controlling for socio-demographic factors. Participants were tested with a general anamnesis, a neuropsychological assessment, measures of explorations and the Landmark Positioning on a Map task. The results showed: (a) a modest difference in performance with categorical spatial relations; (b) a larger difference in coordinate spatial relations; (c) a significant moderating effect of age on the relationship between familiarity and spatial relations, with a stronger relation among the elderly than the young. Ceteris paribus, the role of direct experience with exploring their hometown on spatial mental representations appeared to be more important in the elderly than in the young. This advantage appears to make the elderly wiser and likely protects them from the detrimental effects of aging on spatial mental representations.
