The Eagle
No full textSeaState5 wants to facilitate the monitoring process for seabed cables of offshore wind farms. The company wants to achieve this by creating an unmanned vessel, named the Eagle, which can be analyzed from a remote location.As students from TU Delft, we have been tasked to create a software framework that allows the Eagle to go to a location by receiving instructions from the user, and to send environmental data back to shore via a long-range connection. In addition, telemetry should be possible using short-range communication.The software framework for the Eagle has been built with the design goals of modularity and stability in mind. The user is able to configure the Eagle by adjusting a configuration file. This way, the Eagle pursues a modular design; sensor can be attached and detached without changing the software, only an alteration of the configuration file is required. The Eagle is capable of collecting environmental data, and storing it into a local database. The Eagle also contains in-memory data storage for each sensor. Periodically, the Eagle will send data to the cloud using long range communication. And at last, he Eagle is also capable of retrieving instructions from the cloud. Those instructions allow the eagle to perform specific tasks

Embodied simulation: Mirror neurons, neurophysiological bases of intersubjectivity, and some implications for psychoanalysis
No full textThe neural circuits activated in the person carrying out actions, expressing emotions, and experiencing sensations are also automatically activated in the observer of these actions, emotions, and sensations. These circuits configure a mirror neuron system. These findings of shared activation suggest a functional mechanism of "embodied simulation" which consists of the automatic, unconscious, and non-inferential simulation in the observer of actions, emotions, and sensations carried out and experienced by the observed. This shared neural activation pattern and the accompanying "embodied simulation" constitutes a fundamental biological basis for understanding another's mind. The implications of this perspective for psychoanalysis are discussed, particularly regarding unconscious communication, projective identification, countertransference, attunement, empathy, autism, and therapeutic action
Investigating the decline of the Martial Eagle (Polemaetus bellicosus) in South Africa
No full textThe Martial Eagle (Polemaetus bellicosus) is an African endemic that occurs over a wide range of habitats but at naturally low densities. There is concern throughout its range that it is declining and it now appears to be strongly reliant on protected areas. It is classified globally as Near Threatened by the IUCN with a current consultation underway to up-list it to Vulnerable or Endangered. In this project I describe and explore the decline of the species across South Africa, using data from two repeated national bird surveys - South African Bird Atlas Projects (SABAP 1: 1987-1993; SABAP 2: 2007-2012). These analyses suggest a relatively uniform decline across South Africa in Martial Eagle reporting rates of 59% over the last 20 years. Alarmingly, these declines also occurred in protected areas, including the traditional strongholds of the Kruger National Park (54% decline) and the Kalahari National Park (44% decline). Independent survey data, undertaken in the Kalahari National Park, confirmed these declines and reinforced the validity of using the two SABAP surveys to examine population change. Within protected areas, the species is still encountered five times more frequently and is six times as abundant as compared to outside protected areas. Between the biomes, the species is encountered the least and has the lowest abundance in the Grassland biome where tree density is low, and has the highest abundance in the Savanna biome where tree density is higher. Examining environmental correlates of these population changes provided some support for two hypotheses on the causes of these declines, with climate change (increases in temperature) and power line densities negatively associated with changes in reporting rates. Although this analysis also suggested support for declines being associated with avian prey declines, this was unlikely to be a major driver nationally, because I found that overall avian prey species actually increased over this time period. Within Kruger National Park changes in reporting rates were negatively associated with Elephant densities, which may be related to a reduction in nesting opportunities (large trees) for the species. These results are an initial attempt to assess the broad drivers of decline and should help focus and prioritize further detailed research to elucidate the mechanisms behind this species decline

Place-based attributes predict community membership in a mobile phone communication network.
No full textSocial networks can be organized into communities of closely connected nodes, a property known as modularity. Because diseases, information, and behaviors spread faster within communities than between communities, understanding modularity has broad implications for public policy, epidemiology and the social sciences. Explanations for community formation in social networks often incorporate the attributes of individual people, such as gender, ethnicity or shared activities. High modularity is also a property of large-scale social networks, where each node represents a population of individuals at a location, such as call flow between mobile phone towers. However, whether or not place-based attributes, including land cover and economic activity, can predict community membership for network nodes in large-scale networks remains unknown. We describe the pattern of modularity in a mobile phone communication network in the Dominican Republic, and use a linear discriminant analysis (LDA) to determine whether geographic context can explain community membership. Our results demonstrate that place-based attributes, including sugar cane production, urbanization, distance to the nearest airport, and wealth, correctly predicted community membership for over 70% of mobile phone towers. We observed a strongly positive correlation (r?=?0.97) between the modularity score and the predictive ability of the LDA, suggesting that place-based attributes can accurately represent the processes driving modularity. In the absence of social network data, the methods we present can be used to predict community membership over large scales using solely place-based attributes
A close eye on the eagle-eyed visual acuity hypothesis of autism
No full textAutism spectrum disorders (ASD) have been associated with sensory hypersensitivity. A recent study reported visual acuity (VA) in ASD in the region reported for birds of prey. The validity of the results was subsequently doubted. This study examined VA in 34 individuals with ASD, 16 with schizophrenia (SCH), and 26 typically developing (TYP). Participants with ASD did not show higher VA than those with SCH and TYP. There were no substantial correlations of VA with clinical severity in ASD or SCH. This study could not confirm the eagle-eyed acuity hypothesis of ASD, or find evidence for a connection of VA and clinical phenotypes. Research needs to further address the origins and circumstances associated with altered sensory or perceptual processing in ASD
