Since, in the same vein as public spaces, urban green spaces play a significant role in establishing social interactions in the Iranian cities, security concerns need to be taken more seriously in such places than other social environments, the insufficiency of which could diminish their functional capacity. This could in turn lead to a source of subsequent difficulties in urban spaces. Therefo...

In this paper, we propose a robust and efficient background subtraction algorithm for a vision-based user interface. We separate a user of interest as precisely as possible from the acquired images in order to convey the user’s intension properly into the system through the vision-based user interface. Although the background subtraction techniques have been adopted in many vision-based interfa...

In this paper the authors introduce PERCEPT-V indoor navigation for the blind system. PERCEPT-V enhances PERCEPT system by enabling visually impaired users to navigate in open indoor spaces that differ in size and lighting conditions. The authors deploy visual tags in the environment at specific landmarks and introduce a visual tag detection algorithm using a sampling probe and cascading approa...

Geographic Information System (GIS) is a computer-based system used to store and manipulate geographic information. In this study, GIS is used to obtain information about "open green space of urban areas" (RTHKP). Office of street lighting and Cemetery Palembang is one agency that regulates the green open spaces but not using media such as websites that support the community to get information ...

This paper suggests a method how to predict electric lighting energy savings for photocell controls in daylit spaces taking manual blind control into account. The method predicts lower but supposedly more “realistic” lighting energy savings than conventional simulation approaches. On the other hand, predicted savings are larger than those predicted by ASHRAE 90.1 power adjustment factors. The m...

BACKGROUND Educational evaluation is a process which deals with data collection and assessment of academic activities' progress. In this research, educational evaluation of Dentistry School of Tehran University of Medical Sciences, which trains students in undergraduate and residency courses, was studied. METHODS This descriptive study was done with a model of educational evaluation in ten st...

To evaluate the performance of buildings in use and to predict performance during design, it is necessary to identify what the appropriate measures of performance should be, when and how measures should be collected, and how results will be interpreted to determine success or failure. As noted in Chap. 1, one of the central barriers to effective daylighting is that daylighting performance is of...
