Adaptive Embedded Roadmaps for Sensor Networks

In this paper, we propose a new approach to wireless sensor network assisted navigation while avoiding moving dangers. Our approach relies on an embedded roadmap in the sensor network that always contains safe paths. The roadmap is adaptive, i.e., it adapts its topology to changing dangers. The mobile robots in the environment uses the roadmap to reach their destinations. We evaluated the performance of embedded roadmap both in simulations using realistic conditions and with real hardware. Our results show that the proposed navigation algorithm is better suited for sensor networks than traditional navigation field based algorithms. Our observations suggest that there are two drawbacks of traditional navigation field based algorithms, (i) increased power consumption, (ii) message congestion that can prevent important danger avoidance messages to be received by the robots. In contrast, our approach significantly reduces the number of messages on the network (up to 160 times in some scenarios) and power consumption while increasing the navigation performance

The Father Birth

This creative dissertation is a fabulist and satirical novel. The book follows the story of main character and narrator Earleen, an atypical and hyper-intelligent sixteen-year-old who continues to be traumatized by her sociopathic father even after he dies. A self-taught bookworm born in the early 1980s, her formative years were spent trapped inside her parents\u27 rural methamphetamine cookhouse. When her parents blow up inside their house during a drug-manufacturing incident on the eve of Earleen\u27s early adolescence, she finds herself in the arms of an affluent adoptive couple (Dennis Stark, a fertility specialist, and his homemaker wife Beverly) who have been unable to conceive. Her presence is an unwelcome addition to Dennis\u27s mother, who is a mute stroke victim and was formerly the couple\u27s coddled center of attention. Throughout her childhood, Earleen had a tumultuous relationship with her reckless father (known as Pops ), whose drug-addled paranoia often resulted in her abuse and torture. Although Earleen\u27s mother never reappears to haunt her after the explosion, Pops\u27 spirit is determined to find a way to get back to Earth and rejoin the living. He frequently visits Earleen — his ghost can return through the medium of liquid, and he\u27s convinced she\u27s the only one who can help him get back. Though no longer starved and stabbed, Earleen is still invisible and voiceless in her new home. Her adoptive mother Beverly values Earleen only as a path to grandchildren and is disappointed Earleen doesn\u27t share her obsession with outward beauty. Dennis and Beverly live in total ignorance of Earleen\u27s hauntings, although Dennis\u27 mother seems to detect something amiss. Dismayed by the social aspects of school, Earleen graduates early in order to take on secretarial work at Dennis\u27 fertility clinic. Her father\u27s ghost, which is growing weaker but also more desperate and therefore dangerous, decides that this is his ticket back to life: he is convinced he can enter into a donor sample just as he can enter other liquid, and hypothesizes that if Earleen impregnates herself with the sample, he can be reborn. Although Earleen doesn\u27t want to help him or to have him back among the living, she is afraid of him, and he threatens the safety of her new family if she doesn\u27t obey. Earleen chooses a donor and successfully impregnates herself, but weeks later she runs into the unknowing donor at the store and agrees to go on a date with him. A relationship begins, and Earleen finds herself in the precarious situation of carrying the baby of a man who doesn\u27t know she\u27s pregnant, doesn\u27t know it\u27s by his sperm, and has never slept with her. Worse yet, though Huckle soon shows himself to be self-absorbed and misogynistic, Earleen never seems to have a say in how quickly their relationship is moving forward. Inside a barn during a storm, she gives birth to an inky creature that crawls into the rain. Yet once born, her father does not stay away and leave her alone as promised. His development is not going as planned, and each year of his new life seems to make him weaker rather than stronger. When Earleen becomes a young bride and gets pregnant, Pops returns wanting to overtake the fetus and be reborn once more in the hopes that the process will be more successful the second time around. She must find a way to protect herself from Pops and cut him off from the living world

Cognitive modeling of social behaviors

To understand both individual cognition and collective activity, perhaps the greatest opportunity today is to integrate the cognitive modeling approach (which stresses how beliefs are formed and drive behavior) with social studies (which stress how relationships and informal practices drive behavior). The crucial insight is that norms are conceptualized in the individual mind as ways of carrying out activities. This requires for the psychologist a shift from only modeling goals and tasks —why people do what they do—to modeling behavioral patterns—what people do—as they are engaged in purposeful activities. Instead of a model that exclusively deduces actions from goals, behaviors are also, if not primarily, driven by broader patterns of chronological and located activities (akin to scripts). To illustrate these ideas, this article presents an extract from a Brahms simulation of the Flashline Mars Arctic Research Station (FMARS), in which a crew of six people are living and working for a week, physically simulating a Mars surface mission. The example focuses on the simulation of a planning meeting, showing how physiological constraints (e.g., hunger, fatigue), facilities (e.g., the habitat’s layout) and group decision making interact. Methods are described for constructing such a model of practice, from video and first-hand observation, and how this modeling approach changes how one relates goals, knowledge, and cognitive architecture. The resulting simulation model is a powerful complement to task analysis and knowledge-based simulations of reasoning, with many practical applications for work system design, operations management, and training
