Users rely increasingly on Location-Based Services (LBS) and automated navigation/guidance systems nowadays. However, while such services are easily implemented in outdoor environments using Global Positioning System (GPS) technology, a requirement still exists for accurate localization and guidance schemes in indoor settings. Accordingly, the present study presents a methodology based on GPS, ...

With the development of localization technologies, researchers solve the indoor localization problems using diverse methods and equipment. Most localization techniques require either specialized devices or fingerprints, which are inconvenient for daily use. Therefore, we propose and implement an accurate, efficient and lightweight system for indoor direction finding using common smartphones and...

Educational ergonomics is defined as that field of human factors/ergonomic science concerned with the interaction of educational performance and educational design. The premise of educational ergonomics is that student performance to a substantial degree is context specific---specialized in relation to specific design factors---and that ergonomic interventions directed at design improvements th...

The early stages of building design include a number of decisions which have a strong influence on the performance of the building throughout the rest of the process. It is therefore important that designers are aware of the consequences of these design decisions. This paper presents a method for making informed decisions in the early stages of building design to fulfil performance requirements...

This paper presents a case study of a Wi-Fi system operating in the frequency of 2.4 GHz. Two certain types of WLAN environments are examined: a home environment (typical residence) and a complex office environment. Experimental acquired data, for both single floor and multiple floor scenarios, are compared with the theoretical values provided by an existing plethora of indoor RF models, which ...

The key to navigate in a 3-D environment or designing autonomous vehicles that can successfully maneuver and manipulate objects in their environment is the ability to create, maintain, and use effectively a 3-D digital model that accurately represents its physical counterpart. Virtual exploring of real places and environments, either for leisure, engineering design, training and simulation, or ...

BACKGROUND Allergenic pollen exposure is mostly seen as an outdoor phenomenon but studies have shown an indoor exposure: different pollen species including birch and grass pollen in houses, schools, and shops are leading to long-lasting symptoms even after the pollen season because pollen settle on surfaces and re-enter the indoor air depending on ventilation. To reduce indoor pollen load, wind...

Most traditional elementary school classrooms here do not have air-conditioners and it often feel stuffy in classrooms located in the top floors. In addition, traditional classrooms widely have noise problem, so do the open educational classrooms. If the windows and doors are closed to reduce noise, it will result in the phenomenon of stuffiness, which largely prevents the external air entering...

a rural environment is reflect of the historical practices over the time, mutually feedback of human settle, activities nature and include aesthetic quality, environmental function, local knowledge, tradition and customs. but rapid growth of consuming economy and emphases only on functional character without linkage to different environmental socio-cultural and economic condition led to model o...

Educational buildings should provide a secure, healthy, and comfortable indoor environment for students since they spend noteworthy part of their time inside. The present study aims to identify assess the key indicators related light air quality campus classroom, which contributes health students. are chosen from an existing green rating tool, WELL Building Standard (WBS). research methodology ...
