Attachment to a place is a positive emotional relation between a person and a place that leads to the significance of a place for the people staying there. Several studies have been presented about the sense of attachment to one or more locations around the world that each of them has evaluated the subject from a specific view and has achieved different results. This research tries to assess th...

Our view of environment for context-aware applications is a place, which contains devices, digital services and people with their social contexts. Therefore, understanding place will contribute to the successful of applications. In this paper, we introduce two issues: (i) there is a need for sharing context knowledge about place; (ii) using a multiagent framework for modeling place will improve...

Robotic mapping and localization systems typically operate at either one fixed spatial scale, or over two, combining a local metric map and a global topological map. In contrast, recent high profile discoveries in neuroscience have indicated that animals such as rodents navigate the world using multiple parallel maps, with each map encoding the world at a specific spatial scale. While a number ...

Search in a complex design space (e.g. in VLSI design) is only feasible when it is factored into smaller ones. A common and useful factoring is the hierarchy of abstraction. Such problems are then attacked by linking together stochastic search programs. At each point in the design process it is necessary to choose whether to continue looking for a better design at the current level, or working ...

The continued scaling of the CMOS technology has led us into the deep submicron regimes where design is not limited by the functionality on a chip but is constrained with its power consumption. In this paper, we present some widely used techniques for static and dynamic power minimisation in modern VLSI circuits. These techniques are applicable on the different stages of the system design, star...

This paper presents a software system for generation of VLSI layouts. Its main advantages are minimal hardware requirements and its independence of programming languages, hardware platforms and fabrication processes. It is thus designed for use in algorithmdevelopment and universitary backgrounds.

The two-dimensional discrete cosine transform (2D-DCT) is at the core of image encoding and compression applications. We present a new architecture for the 2D-DCT which is based on row-column decomposition. An efficient architecture to compute the one-dimensional fast direct (1D-DCT) and inverse cosine (1D-IDCT) transforms, which is based in reordering the butterflies after their computation, i...
