Developing effective urban planning approaches is a major challenge for outdoor and indoor environments. Wayfinding in unfamiliar indoor environments is a prime task which everyone would be encountered. The development of assistive technologies to aid wayfinding is hampered by the lack of reliable and cost-efficient methods providing location information in the environment. We have applied RFID...

This paper will introduce a framework for characterizing real environments, using recorded force/displacement data, for use in haptic display. Steps in the framework include data acquisition, identification, model verification, and implementation. Identification and implementation will be developed in detail. After obtaining a conceptual understanding of the roles data acquisition and model ver...

By 2020 it is predicted that chronic diseases will account for almost three quarters of all deaths. According to the World Health Organization the elderly population is expected to become 1.2 billion in 2025. This aging problem contributes greatly to chronic diseases like Alzheimer’s; Elderly are suffering from Alzheimer’s. The major implications of Alzheimer’s are patient safety and care. The ...

For blind and visually impaired people is quite impossible to be autonomous in the contemporary world, in which we are completely surrounded by information, but only visual information... When looking for a product in shops, or ordering at the restaurant, or when they want to listen to the music on a CD, blind persons encounter the visual barrier of the written language, that only the help of a...

In this paper, a real-coded genetic algorithm is proposed for identification of time delay systems from step responses. FOPDT (First-Order Plus Dead-Time) and SOPDT (SecondOrder Plus Dead-Time) systems, which are the most useful processes in this field, but are difficult for system identification because of a long dead-time problem and a model mismatch problem. Genetic algorithms have been succ...

In this paper, tagging techniques are employed to identify monitored inhabitants in smart environments. The aim of the work is to recognize the presence of the tagged inhabitants in different areas of the environment. RSSI based localizing agents are used in separate areas to measure the distance of the tagged persons from the reader agents. Then a clustering method is applied to the readings f...

BACKGROUND Nosocomial infections place a substantial burden on health care systems and represent one of the major issues in current public health, requiring notable efforts for its prevention. Understanding the dynamics of infection transmission in a hospital setting is essential for tailoring interventions and predicting the spread among individuals. Mathematical models need to be informed wit...

This paper describes an augmented reality system with a wearable computer to overlay an annotation relative to the real world. To realize an augmented reality system, a position of user’s viewpoint is needed for acquiring a relationship between the real and virtual coordinate systems. However, it is difficult that the user’s viewpoint is accurately measured in both inand out-door scene. In this...

background: various decisions have been made on technology application at all levels of the health system in different countries around the world. health technology assessment is considered as one of the best scientific tools at the service of policy- makers. this study attempts to investigate the current challenges of iran’s health technology assessment and provide appropriate strategies to es...

NEC’s video identification technology enables instant video content identification by extracting a unique descriptor called a “video signature” from video content. This technology is approved as the MPEG-7 Video Signature Tool; an international standard of interoperable descriptors used for video identification. The video signature is an extremely robust tool for identifying videos with alterna...
