The paper deals with a systematic approach to the control system design with a final goal to efficiently control some living conditions in a test chamber. The mathematical model was implemented in MATLAB Simulink environment. The structure is modular, the robust numerical algorithms give accurate results and fast simulation runs. The developed simulator gives an ideal environment for the design...

BACKGROUND Architectural design has the potential to influence the microbiology of the built environment, with implications for human health and well-being, but the impact of design on the microbial biogeography of buildings remains poorly understood. In this study we combined microbiological data with information on the function, form, and organization of spaces from a classroom and office bui...

Nowadays, with the rapid develpopment of wireless network and multimedia service, indoor wireless positioning technology is developing very fast. At this point, many new technology emerges. People's demand and requirement for positioning and navigation gradually improve a lot, particularly for complex indoor environment. Indoor positioning is often limited to time and position precision and com...

In this paper indoor localization system based on the RF power measurements of the Received Signal Strength (RSS) in WLAN environment is presented. Today, the most viable solution for localization is the RSS fingerprinting based approach, where in order to establish a relationship between RSS values and location, different machine learning approaches are used. The advantage of this approach bas...

OBJECTIVES Some plants were placed in indoor locations frequented by asthmatics in order to evaluate the quality of indoor air and examine the health benefits to asthmatics. METHODS The present study classified the participants into two groups: households of continuation and households of withdrawal by a quasi-experimental design. The households of continuation spent the two observation terms...

A simple and successful design for a panoramic stereo system that uses a single camera and multiple mirrors is presented. A wide-baseline stereo enhances the three-dimensional reconstruction accuracy even with a single camera. The feasibility of the system as a practical stereo sensor has been demonstrated with experiments in an indoor environment.
