In these days, the development of positioning technology for realizing ubiquitous environments has become one of the most important issues. The Global Positioning System (GPS) is a well-known positioning scheme, but it is not suitable for positioning in in-door/building environments because it is difficult to maintain line-of-sight condition between satellites and a GPS receiver. To such proble...

Location-based service is one of the most popular buzzwords in the field of U-cities. Positioning a user is an essential ingredient of a location-based system in a U-city. For outdoor positioning, GPS based practical solutions have been introduced. However, the measurement error of GPS is too big for it to be used for U-campus services, because the size of a campus is smaller than that of a cit...

The effectiveness of the work performed during disaster relief efforts is highly dependent on the coordination of activities conducted by the first responders deployed in the affected area. Such coordination, in turn, depends on an appropriate management of geo-referenced information. Therefore, enabling first responders to count on positioning capabilities during these activities is vital to i...

Many ubiquitous computing applications rely upon location information describing the positions of people and devices. To date, location systems for ubiquitous computing have commonly supplied position data which has a single system-wide reference [1]. Examples include 3D coordinates inside a building, or public areas on a campus. In order to provide statically-referenced data, such systems nece...

Positioning of mobile devices is a core requirement in many mobile computing applications. Typically, such applications use external infrastructure installed in the environment to obtain position information. Several different technologies have been investigated such as ultra sound, magnetic fields or inertial systems. In contrast to most of the established location systems, a promising approac...

The nucleus is the largest organelle and is commonly depicted in the center of the cell. Yet during cell division, migration, and differentiation, it frequently moves to an asymmetric position aligned with cell function. We consider the toolbox of proteins that move and anchor the nucleus within the cell and how forces generated by the cytoskeleton are coupled to the nucleus to move it. The sig...

Academic writing is not just about presenting a set of ideas, but through the act of writing, the authors position themselves as individuals having particular identities which mostly reflect the dominant sociocultural values and practices of the discourse communities in which they are living and performing. The present study, using a mixed method approach, attempted to explore the evidences of ...
