We describe the architecture of iPOS (short for iPAQ Positioning System), a fault-tolerant and adaptive self-positioning system with quality-of-service guarantees for resource-limited mobile devices. The architecture is based on a novel sensor modelling technique in combination with a probabilistic data-fusion engine, which is capable of efficiently combining the location information obtained f...

This paper discusses some of the requirements for the control architecture of an intelligent human-like agent with multiple independent dynamically changing motives in a dynamically changing only partly predictable world. The architecture proposed includes a combination of reactive, deliberative and meta-management mechanisms along with one or more global \alarm" systems. The engineering design...

From 60 decade  sustainability issues  and sustainable developing  have opened a way in scientific meetings associated with  environment and urbanization and architecture. Sustainability goals are improving of environment situation , less pollution  and at least interference on  land and interaction of  natural and artificial environment , that most of these cases attracted attention in archite...

This paper discusses the design and development of a FPGA-based chirp generator for high resolution Unmanned Aerial Vehicle (UAV) Synthetic Aperture Radar. The desired bandwidth of the chirp signal is 100MHz (combination of I and Q channels) with a chirp rate of 5MHz/μs. Two algorithms based on the Memory-based architecture and the Direct Digital Synthesizer (DDS) architecture are presented. Th...

We reflect on our experiences using an experimental platform for rapidly prototyping physical control configurations for multiplayer games. We describe how the architecture permits novel forms of collaborative play through the combination and configuration of basic tangible/physical building blocks, the deep integration between physical and virtual objects, and flexibility in how physical and v...

We describe an architecture called WebFINDIT that allows dynamic couplings of Web accessible databases based on their content and interest. We propose an implementation using WWW, Java, JDBC, and CORBA’s ORBs that communicate via the CORBA’s IIOP protocol. The combination of these technologies offers a compelling middleware infrastructure to implement wide-area enterprise applications. In addit...

Mohammad-Karim Pirnia, one of the most prominent scholars of the history of Iranian architecture, has recorded two major achievements: the principles of Iranian architecture and the stylistics of Iranian architecture. In this article we will discuss his suggested principles for Iranian architecture. For this purpose, we will first show how his five principles have evolved and completed th...

abstract man has a social life and during his life he establishes the most important social institution which is known as a family. this social institution, the family, evokes the architecture of a house. the formation of the house as a family behavioral setting is related to the social behavior, also culture and ethics of the members of the family. more than 90% of the buildings in most tradit...

Breadth-First Search (BFS) is widely used in real-world applications including computational biology, social networks, and electronic design automation. The most effective BFS approach has been shown to be a combination of top-down and bottom-up approaches. Such hybrid techniques need to identify a switching point which is conventionally found through expensive trial-and-error and exhaustive se...

a comparative study of the corresponding styles of western and iranian modern architecture has hardly ever been carried out in detail. this paper aims to sketch out an outline for such an investigation and to present a summary of empirical evidence accompanied by field observations to elaborate the ongoing trend of relationship between architectural styles in iran and that of the west. this is ...
