Indoor Navigation System for the Visually Impaired with User-centric Graph Representation and Vision Detection Assistance
Independent navigation through unfamiliar indoor spaces is beset with barriers for the visually impaired. Hence, this issue impairs their independence, self-respect and self-reliance. In this thesis I will introduce a new indoor navigation system for the blind and visually impaired that is affordable for both the user and the building owners.
Outdoor vehicle navigation technical challenges have been solved using location information provided by Global Positioning Systems (GPS) and maps using Geographical Information Systems (GIS). However, GPS and GIS information is not available for indoor environments making indoor navigation, a challenging technical problem. Moreover, the indoor navigation system needs to be developed with the blind user in mind, i.e., special care needs to be given to vision free user interface.
In this project, I design and implement an indoor navigation application for the blind and visually impaired that uses RFID technology and Computer Vision for localization and a navigation map generated automatically based on environmental landmarks by simulating a user’s behavior. The focus of the indoor navigation system is no longer only on the indoor environment itself, but the way the blind users can experience it. This project will try this new idea in solving indoor navigation problems for blind and visually impaired users
Advanced Mobile Robotics: Volume 3
Mobile robotics is a challenging field with great potential. It covers disciplines including electrical engineering, mechanical engineering, computer science, cognitive science, and social science. It is essential to the design of automated robots, in combination with artificial intelligence, vision, and sensor technologies. Mobile robots are widely used for surveillance, guidance, transportation and entertainment tasks, as well as medical applications. This Special Issue intends to concentrate on recent developments concerning mobile robots and the research surrounding them to enhance studies on the fundamental problems observed in the robots. Various multidisciplinary approaches and integrative contributions including navigation, learning and adaptation, networked system, biologically inspired robots and cognitive methods are welcome contributions to this Special Issue, both from a research and an application perspective
A "Social Bitcoin" could sustain a democratic digital world
A multidimensional financial system could provide benefits for individuals,
companies, and states. Instead of top-down control, which is destined to
eventually fail in a hyperconnected world, a bottom-up creation of value can
unleash creative potential and drive innovations. Multiple currency dimensions
can represent different externalities and thus enable the design of incentives
and feedback mechanisms that foster the ability of complex dynamical systems to
self-organize and lead to a more resilient society and sustainable economy.
Modern information and communication technologies play a crucial role in this
process, as Web 2.0 and online social networks promote cooperation and
collaboration on unprecedented scales. Within this contribution, we discuss how
one dimension of a multidimensional currency system could represent
socio-digital capital (Social Bitcoins) that can be generated in a bottom-up
way by individuals who perform search and navigation tasks in a future version
of the digital world. The incentive to mine Social Bitcoins could sustain
digital diversity, which mitigates the risk of totalitarian control by powerful
monopolies of information and can create new business opportunities needed in
times where a large fraction of current jobs is estimated to disappear due to
computerisation.Comment: Contribution to EPJ-ST special issue on 'Can economics be a Physical

05-20-1974 Memorandum to the Conference
On April 24, 1972, after oral argument, we granted Vermont\u27s motion to file a complaint against New York and the International Paper Company which alleged that as a result of discharge of wastes, largely from International\u27s mills, that company and New York are responsible for a sludge bed in Lake Champlain and Ticonderoga Creek that has polluted the water, impeded navigation, and constituted a public nuisance. 406 U.S. 186. Issue was joined and the Honorable R. Ammi Cutter was appointed Special Master. 408 U.S. 917. Later the United States sought leave to intervene stating it had numerous interests in these waters under federal statutes. We referred the motion to the Special Master, 409 U.S. 1103, who granted intervention. During the year 1973, 75 days of testimony were received. Vermont presenting substantially all of her direct case, New York has put in about half of her direct case. Neither International nor the United States up to now has offered any evidence
