In this paper, a mechanism is designed for integration of inertial navigation system information (INS) and global positioning system information (GPS). In this type of system a series of mathematical and filtering algorithms with Tightly Coupled techniques with several objectives such as application of integrated navigation algorithms, precise calculation of flying object position, speed and at...

At present a great deal of research is being done in different aspects of Content-Based Image Retrieval (CBIR). Representation of graphical object location in an image is one of the important tasks that must be dealt with in image DB as an intermediate stage prior to further image retrieval. The issue we address is the principal component analysis (PCA) applied to spatial representation of obje...

Identification of a fixated object in a visual display is facilitated by integrating information from a preview of that object in the periphery with information extracted on the subsequent foveal fixation (Pollatsek, Rayner, & Collins, 1984). These experiments investigated the extent to which this integration is dependent on the spatial location of the information remaining constant. Two previe...

Object-based attention would result if target appearing at an invalid location on the same object is detected more quickly than target on an equidistant location on different object (e.g., Egly, Driver, & Rafal, 1994). Three experiments examined the form of object-based attention typical object-based attention paradigms elicit (object-based benefits from the spread of attention across objects o...

The primate visual system is considered to be segregated into ventral and dorsal streams specialized for processing object identity and location, respectively. We reexamined the dorsal/ventral model using a stimulus-driven approach to object identity and location processing. While looking at repeated presentations of a standard object at a standard location, subjects monitored for any infrequen...

The ability to change the physical location of objects is considered indispensable in today’s highly distributed computing world. As a direct offspring of process migration, object-oriented operating systems now offer object migration as a core mechanism. These systems usually equate migration with a change in physical location. Location is only one attribute whose changes are worth considering...

The project described in this paper has the aim of demonstrating that whisker sensors can be used as a rapid and effective form of robot sensing. Previously a single whisker sensor has been demonstrated mounted on a mobile robot for gathering information about the surface profile of objects close to the robot. This work has now been extended to an array of eight whiskers mounted on a robot that...

The expanding use of location-based services has profound implications on the privacy of personal information. If no adequate protection is adopted, information about movements of specific individuals could be disclosed to unauthorized subjects or organizations, thus resulting in privacy breaches. In this paper, we propose a framework for preserving location privacy in moving-object environment...

In distributed environments, location control of objects among hosts is a crucial concern. This paper proposes a new mechanism of object location control using meta-level programming which provides the following advantages to programmers. First, the description of location control can be separated from the application program by exploiting the meta-level architecture. This separation makes it e...
